Hello from MrBillDoesMath!

Answer:

11.1

Discussion:

cos(42) = x / 15 => multiply both sides by 15

x = 15 * cos(42) => as cos(42) = .743 approx

x = 15 * (.743)

x = 11.15

Thank you,

MrB

Use substitution to solve each system of equations X=y-2 4x+y=2

Mariulka [41]

Answer:

Step-by-step explanation:

x = y - 2.........(1)

4x + y = 2......(2)

Substituting x in (1) in (2)

4(y - 2) + y = 2

4y - 8 + y = 2

5y = 2 + 8

5y = 10

y = 10/5

y = 2

Putting x in (1)

x = y - 2

x = 2 - 2

x = 0

For every 24meals Momoka prepared for customers last night, she prepared 2 meals for employees. Momoka prepared 156 meals.

Olenka [21]

Answer:

144 meals for customers and 12 meals for employees.

Step-by-step explanation:

156/24=6.5

6 x 24 =144

156-144=12

It adds up to be simple numbers, if it didn't it would make sense. For example, she wouldn't serve 6 and a half people. She would serve either 6 people or 7 people. She wouldn't serve 11.3973043 meals. She would serve either 11 meals or 12 meals.

Curtis threw 15 darts at a dartboard.40% of his darts hit the bull’s eye.how many darts not hit the bulls eye?

Harlamova29_29 [7]

Answer:

Step-by-step explanation:

The number of darts that failed to hit the bulls eye is 40% of 15 subtracted from 15

Since 40% of the darts hit the bulls eye .

Therefore

40% of 15

40/100 x 15

0.4 x 15

This means that 6 darts hit the bulls eye.

Therefore,number of darts that did not hit the bulls eye is

15 - 6 = 9

9 darts failed to hit the bulls eye
