beks73 [17]

Answer:

$12.99

Step-by-step explanation:

This is because 15.75+17.5= 33.25. 46.24-33.25= 12.99 and therefore, a small pizza should cost 12.99.

If 3 cot theta= 2, find the value of 2sin theta -3cos theta /2sin theta +3cos theta

sergeinik [125]

Answer:

Step-by-step explanation:

Using the trigonometric identity

cotx = $\frac{cosx}{sinx}$

Given

3cotθ = 2 , then

3 $\frac{coso}{sino}$ = 2 ( multiply both sides by sinθ )

3cosθ = 2sinθ ( subtract 3cosθ from both sides )

2sinθ - 3cosθ = 0

Thus

$\frac{2sin0-3cos0}{2sin0+3cos0}$

= $\frac{0}{2sin0+3cos0}$

= 0

Luis bought a pair of pants and a shirt He spent $15 on the pants. He bought five shirts that each cost d dollars less than the

Natali5045456 [20]

15=pants
d less than pants means
15-d

5 of them
5(15-d)=cost of shirts

so total cost=15+5(15-d)

A student rides his bike 6 1/4 miles in 1/3 <br> hour. What is his rate in miles per hour?

Vladimir79 [104]

6 1/4 = 25/4

(25/4)*3 = 75/4

(72+3)/4 = 72/4 + 3/4 = 18 3/4 miles per hour

5. MAPPING Ben and Kate are making a

Rainbow [258]

Answer:

a. 1,000 yards

b. (2, -1)

Step-by-step explanation:

Coordinates of Ben's House = (6, 2)

Coordinates of Kate's House = (-2, -4)

a. Number of yards between Kate and Ben's House using instance formula, $d = \sqrt{(x_2 - x_1)^2 + (y_2 - y_1)^2}$ .

$d = \sqrt{(6 -(-2))^2 + (2 -(-4))^2}$

$d = \sqrt{(8)^2 + (6)^2}$

$d = \sqrt{64 + 36}$

$d = \sqrt{100}$

$d = 10 units$

1 unit = 100 yards

Therefore, 10 units = 1,000 yards.

Kate and Ben's House are 1,000 yards apart.

b. Since Jason's home is halfway between Ben and Kate's House, therefore, Jason's location is the midpoint between Ben and Kate's House. Use the midpoint formula to calculate the coordinates of Jason's location on the map, using (6, 2) and (-2, -4).

$M(\frac{x_1 + x_2}{2}, \frac{y_1 + y_2}{2})$

Plug in the values

$M(\frac{6 +(-2)}{2}, \frac{2 +(-4)}{2})$

$M(\frac{4}{2}, \frac{-2}{2})$

$M(2, -1)$
