​math tests?
​​

Answers

Answer 1
Answer:

Final answer:

To calculate Juan's average math test score, add all the scores together (85, 83, and 93) and then divide by the total number of tests, which is 3. The average score is 87.

Explanation:

The question given is a mathematics problem related to calculating an average. In particular, it is about finding the average test score of Juan's math tests. To find the average of a set of numbers, you add up all the numbers and then divide by the quantity of numbers. In this case, we add the test scores 85, 83, and 93 which gives us a total of 261. Since there are 3 tests, we divide this total by 3. So, Juan's average test score is 261 divided by 3, which equals 87.

the length of a garden is 4 m longer than the width. if the area of the garden is 196m^2, find the width of the garden.

Answers

l = 4 + w 
w = w 
A = 196 m^2

A = lw
A= (4+w)w
196 = w^2 +4w

w^2 + 4w - 196 = 0

The quadratic roots (or zeros) of the function are 12 and -16. 

Since -16 does not make sense as a measure of width, then 12 is the answer. 

A photographer is printing a photograph for a client. The ratio of the photograph’s width to its length is 8:10. The client wants a smaller version of the photograph printed, but the ratio of the width to the length needs to stay the same. If the length of the printed photograph is 5 inches, what should the width be?
3 inches 4 inches 6 inches 7 inches 8 inches

Answers

The ratio is 4:5

because 8 divided by 2 is 4

and 10 divided by 2 is 5

so the answer as said before is 4:5

Find the intercepts for the graph of the equation 8x-4y=24. type an ordered pair for y and x

Answers

X - Intercept: 8x - 4y = 24
                   8x - 4(0) = 24
                       8x - 0 = 24
                            8x = 24
                             8      8
                              x = 3
                        (x, y) = (3, 0)

Y - Intercept: 8x - 4y = 24
                   8(0) - 4y = 24
                       0 - 4y = 24
                           -4y = 24
                            -4     -4
                              y = -6
                       (x, y) = (0, -6)

Final answer:

The intercepts for the graph of the equation 8x-4y=24 are (0, -6) for the y-intercept and (3, 0) for the x-intercept.

Explanation:

To find the intercepts for the graph of the equation 8x-4y=24, we need to substitute 0 for x to find the y-intercept and substitute 0 for y to find the x-intercept.

For y-intercept:

8(0) - 4y = 24

-4y = 24

y = -6

So the y-intercept is (0, -6).

For x-intercept:

8x - 4(0) = 24

8x = 24

x = 3

So the x-intercept is (3, 0).

Thus, the graph has x & y intercepts as (3, 0) and (0, -6) respectively.
