Answer:

6 to 8

Step-by-step explanation:

3 and 8 multiplied by two will give an equivalent ratio

The ratio shows how many times one value is contained in another value.

The ratios that are equivalent to 3 to 8 are:

9/24, 12/32, and 15/40.

The ratio shows how many times one value is contained in another value.

Example:

There are 3 apples and 2 oranges in a basket.

The ratio of apples to oranges is 3:2 or 3/2.

We have,

3:8

= 3/8

We can have many ratios that is equivalent to 3:8

9/24 = (3 x 3) / (3 x 8) = 3/8

12/32 = (4 x 3) / (4 x 8) = 3/8

15/40 = (5 x 3) / (5 x 8) = 3/8

Thus,

The ratios that are equivalent to 3 to 8 are:

9/24, 12/32, and 15/40.

Answer:

6 is b, 7 is c

Step-by-step explanation:

Answer:

#6 wants you to find out what answer from the 4 expressions gives you the least or smallest number. For #7, you need to follow PEMDAS in order to get the right answer.

Step-by-step explanation:

#6, the answers you get are 8, -9, -3, and 9. You need to choose the smallest number. Negative numbers are smaller than positive numbers, so you can immediately eliminate 8 and 9. You have to be careful when comparing negative numbers because the larger negative number is actually smaller than the smaller negative number since it is further away from the zero. So, negative -9 would be smaller than -3 in this case.

#7, I would divide the -720/12 first. This results in -60. Then, divide the -60 by -10. This gives you an answer of positive 6.

ANSWERS:

#6 : B

#7 : C

Answer:

There are 32 students.

Step-by-step explanation:

If there are six 8-slice pizzas, that means that there is 48 slices total. If each student ate 1 1/2 slices, you can divide 48 and 1.5, and you will get 32. That is the number of students in the class. Hope this helps!

Answer:

They did not run at the same speed. Calculation of their speed shows that Jada was running at a higher speed.

Step-by-step explanation:

Let's first calculate the speed of each person using the units provided so that we  do not complicate the question.

speed =  distance covered/time taken

Andre's speed = 2 km/15 min = 0.133 km/min

Jada's speed = 3km/20 min = 0.15 km/min

Clearly we can see that Jada was running at a higher speed than Andre. The question says they were running at constant speed not equal speed. That just means each person maintained their speed, they did not get faster or slower.

Answer:

44°

Step-by-step explanation:

103+33+x=180

136+x=180

x=180-136

x=44°

[tex]y = \frac{9}{2}(x) + \frac{1}{2}[/tex]

Step-by-step explanation:

Linear equations can be written as

m is [tex]\frac{y_2 - y_1}{x_2 - x_1}[/tex]

b is the y intercept

[tex]\frac{9.5 - 0.5}{2-0}\\ =\frac{9}{2} \\y = \frac{9}{2}x+b\\\frac{1}{2}= \frac{9}{2}(0) + b\\ b = 1/2[/tex]

Answer: The number of books in 6 boxes =  48

The number of books in 10 boxes = 80

The number of books in n boxes = 8n

Step-by-step explanation:

Given : Each box has contains about 8 books.

Total books : (Number of books in each box) x (Numbers of boxes).

Then, the number of books in 6 boxes = 8 x 6 = 48

Similarly,

The number of books in 10 boxes = 8 x 10 = 80

The number of books in n boxes = 8n

Hence, The number of books in 6 boxes =  48

The number of books in 10 boxes = 80

The number of books in n boxes = 8n

Answer:

yes, (1,6) is a solution to the inequality y<4x+2.

Step-by-step explanation:

Looking at the equation we can see that the slope is 4 and the y intercept is 2.

Now we will use the slope that is comprised of the rise over the run which is [tex]\frac{rise}{run}[/tex]

The slope is 4 this means that [tex]\frac{rise}{run}[/tex] = [tex]\frac{4}{1}[/tex] and this shows us that the rise is 4 and the run is 1, so starting at (0,2) you go up 4 and over 1 so our next coordinate would be (1,6)

so the answer is yes, (1,6) is a solution to the inequality y<4x+2.

Answer:

Step-by-step explanation:

The maximum height of the water balloon : 450 m

Quadratic function is a function that has the term x²  

The quadratic function forms a parabolic curve  

The general formula is  

f (x) = ax² + bx + c  

where a, b, and c are real numbers and a ≠ 0.  

The parabolic curve can be opened up or down determined from the value of a. If a is positive, the parabolic curve opens up and has a minimum value. If a is negative, the parabolic curve opens down and has a maximum value  

So the maximum is if a <0 and the minimum if a> 0.  

The formula for finding the coordinates of the maximum and minimum points of the quadratic function is the same.  

The maximum / minimum point of the quadratic function is  

[tex]\rm -\dfrac{b}{2a},-\dfrac{D}{4a}[/tex]

Where  

D = b²-4ac  

The function h (t) = -16x²+160x+50

so the value of a <0, then it has a maximum value  

Because we are looking for maximum height, then we find the value of the y coordinate, with the formula  

[tex]\rm -\dfrac{D}{4a}[/tex]

Questions we might add :

What was the maximum height of the water balloon after it was thrown?

We can also use the first derivative of the above function to find the maximum value

[tex]\tt h'=0=-32x+160\\\\-32x=-160\\\\x=5[/tex]

input to function :

[tex]\tt h=-16x^2+160x+50\\\\h=-16(5^2)+160(5)+50\\\\h=-400+800+50=\boxed{\bold{450~m}}[/tex]
