My answer is 86%.

You take the number you got correct and divide by the number of questions on test.
26 divided by 30 = 0.86666667
Then take that number and multiply it by 100.
0.86666667 times 100 = 86.6666667.
So 86%.

Chris made hamburgers for his family and they each had a diameter of 3 in. If he made 16 hamburgers.
Alenkasestr [34]

Answer:

The total area for all 16 hamburgers is <u>113.04 in²</u>.

Step-by-step explanation:

Given:

Chris made hamburgers for his family and they each had a diameter of 3 in.

If he made 16 hamburgers.

Now, to find the total area for all 16 hamburgers.

So, the diameter 3 in is given and we need first to find the radius:

Radius\ (r)=\frac{Diameter}{2} =\frac{3}{2} =1.5\ in.

Now, to get the area of a hamburger we put formula:

<u><em>(Taking the value of π = 3.14.)</em></u>

Area=\pi r^2\\\\Area=3.14\times (1.5)^2\\\\Area=3.14\times 2.25\\\\Area=7.065\ in^2.

Now. to get the total area of 16 hamburgers by multiplying 16 by the area of a hamburger:

7.065\times 16\\\\=113.04\ in^2.

Therefore, the total area for all 16 hamburgers is 113.04 in².

3/4×-18=1/4×-4 help me slove
WINSTONCH [101]

3/4 x -18 = 1/4 x -4

subtract 1/4 x from each side

3/4 x -1/4 x -18 = 1/4 x- 1/4 x -4

2/4 x - 18 = -4

add 18 to each side

1/2 x -18 + 18 = -4 + 18

1/2 x =14

multiply by 2 on each side

2* 1/2 x = 14 * 2

x =28
