Isaiah and his children went into a grocery store and where they sell apples for $0.50 each and peaches for $1.50 each. Isaiah has $15 to spend and must buy no less than 14 apples and peaches altogether. If Isaiah decided to buy 8 apples, determine the maximum number of peaches that he could buy. If there are no possible solutions, submit an empty answer.

Answers

Answer:

8x0.50=4

15-4=9

9/1.50= 6

6 peaches

Answer:

Maximum of 6 peaches, and 8 apples

Explanation:

Given that the quantity of apples and peaches must total to 14, a total cost of $15, with a cost of $0.50 each for apples and a cost of $1.50 each for peaches, we can create a system of equations to solve for each variable.

0.5a + 1.50p = 15.

a + p = 14.

There are many methods that can be used but the easiest one that works for this problem is elimination.

Start by multiplying the top equation by 2 to get rid of the decimals.

0.5 a × 2 + 1.5 p × 2 = 15 × 2.

Answer:

Rate of change/slope: 35

Miles at 10 hours: 350

Step-by-step explanation:

We can find the rate of change or the slope by using the slope formula below:

m = (y2-y1)/(x2-x1) where m is the slope

To find the slope, we can choose any two points from the table. I will choose (2,70) and (4,140)

m = (140-70)/(4-2)

m = 70/2

m = 35

The rate of change is 35 miles per hour

To find the miles at 10 hours, we can use the equation y = mx + b which is the equation of the line in slope intercept form. However, we will need to find the value of b. To do that, we can plug in any point from the table to find the value of b. I'll choose (2,70).

y = mx + b

70 = 35(2) + b

70 = 70 + b

b = 0

So the equation of the line would be y = 35x. Using this equation, we can find the number of miles at 10 hours:

y = 35(10)

y = 350

The number of miles at 10 hours is 350 miles

Im so confused, how do i get the variance with just the standard deviation

Answers

Answer:

To figure out the variance, divide the sum, 82.5, by N-1, which is the sample size (in this case 10) minus 1. The result is a variance of 82.5/9 = 9.17. Standard deviation is the square root of the variance so that the standard deviation would be about 3.03.

Answer:

The midpoint of XY is point

M(�12, 5). If the coordinates

of X are (3, �3), what are the

coordinates of Y ?

----

Each coordinate of the midpoint is the average

of the corresponding endpoint coordinate.

----

Solve:

Let the coordinates of Y be (x,y)

---

(3+x)/2 = -12

3+x = -24

x = -27

(-3+y)/2= 5

-3+y=10

y = 13

4 times 1/3 (fraction form) will give brainlest

Answers

Answer:

4/3

Step-by-step explanation:

I used a site and my calculator

4 times 1/3 in fraction form is 4/3.

To multiply a whole number by a fraction, we multiply the whole number by the numerator of the fraction and keep the denominator the same.

In this case, we want to multiply 4 by 1/3:

4 × (1/3)

= (4 × 1) / 3

= 4/3

Therefore, 4 times 1/3 in fraction form is 4/3.

i need to find the value of x

Answers

Answer:

x = [tex]\sqrt{21}[/tex]

Step-by-step explanation:

AC² = AB² + BC²

BC² = 3² + x² = 9 + x²

AB² = 7² + x² = 49 + x²

But AC² = (7 + 3)² = 100

∴ 100 = 49 + x² + 9 + x²

2x² + 58 = 100

x² = 50 - 29 = 21

x = [tex]\sqrt{21}[/tex]

Answer: the answer is the square root of 21.

Step-by-step explanation:

What I did was I just multiplied 7 times 3 and got 21 and that was the answer.
