Point Q
Step-by-step explanation:
Find the perfect squares that are either side of 10.
Perfect squares: 1, 4, 9, 16, 25, ....
Therefore, 10 is between 9 and 16.
[tex]\implies \sqrt{9} < \sqrt{10} < \sqrt{16}[/tex]
[tex]\implies 3 < \sqrt{10} < 4[/tex]
So √10 is between 3 and 4.
As 10 is closer to 9 than it is to 16, √10 is closer to √9 than √16, which means that √10 is closer to 3.
Therefore, point Q best represents √10

An acute triangle has two sides measuring 8 cm and 10 cm. What is the best representation of the possible range of values for the third side, s? 2 < s < 18 6 < s < 12. 8 s < 2 or s > 18 s < 6 or s > 12. 8.
Answers
Answer:
Step-by-step explanation:
Method
The smallest the third side can be is something just larger than 2
You get 2 by subtracting10 and 8. The third side is just a bit larger. 8 and 2 will make up the length of 10 so you cannot use 2 itself
The largest value possible is just under 18. You get 18 by adding 8 and 10 together. So to get a triangle, you need just under 18.

A right-angled triangle has an area of
45 cm².
The width of the triangle is n + 3 cm.
The height is 9 cm less than the width.
45 cm²
n + 3
Find the value of n.
n =
Answers
Answer:
A = 1/2 width × height
width = n + 3 cm
height = width - 9 cm
height = n + 3cm - 9cm
height = n - 6cm
A = 1/2 width × height
= 1/2 (n + 3cm) × (n - 6cm)
45cm^2 ×2 = n^2 - 3ncm - 18cm^2
n^2 - 3ncm - 18cm^2 - 90cm^2 = 0
n^2 - 3ncm - 108cm^2 = 0
Find two numbers that their sum is -3 and their product is 108. Therefore, the numbers could be -12 and 9
n^2 - 3ncm - 108cm^2 = 0
n^2 - 12ncm + 9ncm - 108cm^2 = 0
n(n - 12cm) + 9cm(n - 12cm) = 0
(n - 12cm) (n + 9cm) = 0
Either (n - 12cm) = 0 or (n + 9cm) = 0
n = 12cm or n = -9cm
but n = -9cm is invalid because there is no negative distance.
n = 12cm is the answer

The shape is parallelogram.
In parallelogram, alternate interior angles are equal.
9x and 45 are alternate interior angles.
So,
9x = 45
Divide 9 on both sides,
x = 45 / 9
x = 5
In square, opposite side lengths are equal.
2y = 18
Divide 2 on both sides,
y = 18 / 2
y = 9
2 )
The shape is parallelogram.
In parallelogram, the sum of adjacent angles are 180.
In parallelogram, opposite angles are equal.
5y and 55 are adjacent angles,
5y + 55 = 180
5y = 180 - 55
5y = 125
Divide 5 on both sides,
y = 125 / 5
y = 25
11x and 55 are opposite angles,
11x = 55
Divide 11 on both sides,
x = 55 / 11
x = 5
3 )
The shape is parallelogram.
In parallelogram, alternate interior angles are equal.
2x and 30 are alternate interior angles,
2x = 30
Divide 2 on both sides,
x = 30 / 2
x = 15
x + y and 24 are also alternate interior angles,
x + y = 24
15 + y = 24
y = 24 - 15
y = 9
4 )
The shape is a square.
Square is also a parallelogram.
All the four angles in a square are 90 and are equal.
So,
3x = 90
Divide, 3 on both sides,
x = 90 / 3
x = 60
6y = 90
Divide 6 on both sides,
y = 90 / 6
y = 15

$140,000
$150,000
$160,000
$170,000
Answers
Answer:
James invested $160,000
Step-by-step explanation:
- In total, they needed $480,000 to start the business
- 1:2 ratio means one of them payed double the amount than the other
so the expression would be,
2x + x = 480,000
Let x represent how much they each need to invest
the expression can be simplified to,
3x = 480,000
now you need to get x alone, this would be done be dividing both sides by 3
[tex]\frac{3x}{3} = \frac{480,000}{3}\\x = 160,000[/tex]
James invest $160,000
Michael invest $160,000 x 2 = $320,000
and if you add them together, you get the total amount
$320,000 + $160,000 = $480,000

When one event's occurrence or non-occurrence doesn't affect the occurrence or non-occurrence of another event, then such events are called independent events. The correct option is B.
Which pair of events are called independent events?When one event's occurrence or non-occurrence doesn't affect the occurrence or non-occurrence of another event, then such events are called independent events.
Symbolically, we have:
Two events A and B are said to be independent if we have:
[tex]P(A \cap B) = P(A)P(B)[/tex]
Comparing it with the chain rule will give
[tex]P(A|B) = P(A)\\P(B|A) = P(B)[/tex]
Thus, showing that whether one occurred or not, the other one doesn't care about it (independence).
The top shelf of a bookcase holds 6 fiction and 4 nonfiction books. On the bottom shelves, there are 3 fiction and 5 nonfiction books.
When Choosing 2 books that describe a pair of dependent events, one of the fiction books should be chosen from the top shelf, and another one should be a nonfiction book from the top shelf itself.
Hence, the correct option is B.

There are 1,217 students and 75 teachers eating lunch in a cafeteria. Of those people, 562 are drinking chocolate milk. The rest are drinking skim milk. How many people are drinking skim milk?
Answers
Answer: When Rebecca Hodges sent her son to Pre-K in Brooklyn, she was excited for the year to come—full of learning adventures and making new friends. While his education got off to a strong start, Hodges quickly realized something was wrong.
Her son, just five years old, was gaining an alarming amount of weight. Within 6 months, he had gained 11 pounds and his body mass index went from the 60th to the 98th percentile. He began having trouble breathing and sleeping at night. “His diet at home, which was low in sugar, did not change,” she said. “When I brought him to the pediatrician and we started asking him questions about what he was drinking and eating, we realized this was happening because of school.”
Hodges discovered her son was drinking two boxes of chocolate milk a day, each with 20 grams of total sugar, 12 grams of natural sugar from lactose and 8 grams of added sugar. Those 8 grams of added sugar add up to almost one third of a child’s daily sugar allowance according to the American Heart Association and the World Health Organization, which both recommend that children limit sugar to 5 percent of their daily intake —about 6 teaspoons or 25 grams — of added sugar per day.
Hodges’s son is far from a unicorn in the classroom. He is just one of thousands of children growing sick from sugar in a country where the obesity epidemic has reached epic rates and shows no signs of slowing down. Health-care costs related to obesity in this country topped $1.72 trillion dollars in 2018.
In the state of New York, childhood obesity has tripled over the past three decades. In New York City, 40 percent of NYC public school students aged 6 to 12 are overweight or obese. While NYC’s overweight and obesity numbers have been relatively constant over the last 5 years, in communities with underserved populations obesity is on the rise.
Childhood obesity disproportionately affects low-income communities and communities of color. In New York City, children living in the Bronx have the highest prevalence of overweight (43 percent vs. 4 percent in Brooklyn, 40 percent in Staten Island, 39 percent in Queens, 38 percent in Manhattan).
According to the Youth Risk Behavior Survey by the CDC, compared to New York City students, a higher proportion of East and Central Harlem students are overweight and obese. Thirty-five percent of East and Central Harlem students in grades 9-12 are overweight and obese compared to 28 percent in NYC. Obesity rates in low income East Harlem are higher than what they are on the wealthier Upper East Side, just a few short blocks away.
Additionally, according to research reported in Obesity Reviews, obese children and adolescents were approximately “five times more likely to be obese in adulthood than those who were not obese.”
Research also suggests that consuming sweetened beverages such as chocolate milk every day can train a child’s palate to prefer sugar-sweetened foods.
In response, more and more school districts have been removing chocolate milk from their menus. Chocolate milk is banned in Boulder, Minneapolis, Washington D.C., Montgomery County, Maryland, and most recently, San Francisco.
Even New York City’s Department of Corrections (DOC) has phased out sugar-sweetened beverages because of their ties to costly obesity-related diseases. Ten years ago DOC Commissioner Martin Horn told Gothamist, “the move will save money in the long run because healthier inmates will be less prone to strokes, heart attacks or diabetic shock on the city’s watch.” Today, the DOC bans both chocolate milk and juice. And yet, NYC’s Department of Education (DOE) continues to serve chocolate milk (and juice) to 1.1 million children a day. In fact, out of the 1,866 schools within the DOE, only 198 schools opted out of serving chocolate milk in FY 2019.
Rumors have been circulating that DOE may remove chocolate milk from public schools, but it’s deputy press secretary Avery Cohen, would not confirm. She offered this statement: “Our priority is the health and well-being of our students, and every day, we offer a variety of healthy food options that exceed USDA standards. We’ll continue to work with the Department of Education and Department of Health to ensure our meals are nutritious.”
Instead of eliminating chocolate milk as a public health policy, the DOE has outsourced chocolate milk decisions to principals, who may choose to stop serving it in their individual schools. This shifts a huge burden to educators, who want to keep peace with parents of differing views, and who are presumably not health professionals.

Since there are 10 bacteria, the amount of bacteria after 2 minutes is 2560 bacteria
To answer the question, we need to know what rate is
What is rate?A rate is the amount per unit time of a quantity.
Let A₀ = initial amount of bacteria.
Given that the amount of bacteria doubles every 15 seconds, we have that the amount of bacteria left is
A = 2ⁿA₀ where
n = number of 15 seconds that have passed = t/15 where t = time passed.Given that
A₀ = 10 and t = 2 min = 2 × 60 s = 120 s. So, n = t/15 = 120/15 = 8Amount of bacteria after 2 minutesSo, substituting the values of the variables into the equation, we have

A = 2⁸ × 10
A = 256 × 10
A = 2560 bacteria

Answer:
a cone with a circumference of about 63 mm
Step-by-step explanation:
By imagining the triangle rotating around the line in the middle, we can see that the triangle will create a cone, not a cylinder.
If one side of the triangle measures 20 mm, then the radius at the base of our cone will be 10 mm. (20 mm is the diameter and the radius is half of that.)
Use 2πr to solve for the circumference and it comes out to 63.
Thus, the rotated triangle will created a cone with a base circumference of about 63 mm.
