Step-by-step explanation:

because when April stops exercise the calories burnt will reduce

Answer:

it's Time spent exercising.

Step-by-step explanation:

Time spent exercising does not rely on calories burned for its value to change. However, the time spent exercising will determine how many calories are burned. This shows that calories burned is dependent on time spent exercising while time spent exercising is an independent variable.

Answer:

a diagram is necessary. please provide a diagram.

The value of measure of angle R is,

⇒ m ∠R ≈ 22.62°

An angle is a combination of two rays with a common endpoint. The latter is known as the vertex of the angle and the rays as the sides, sometimes as the legs and sometimes the arms of the angle.

Given that;

Reference angle = R

Side opposite to R = 5 cm

Adjacent side length = 12 cm

Thus, applying TOA, we have:

Tan R = opposite/adjacent

Tan R = 5/12

R = tan⁻¹ (5/12)

R ≈ 22.62°

Thus, The value of measure of angle R is,

⇒ m ∠R ≈ 22.62°

Answer:

C(n) = pn

Step-by-step explanation:

Given :

n = time in hours for service call

C = total cost

Total cost = unit cost per hour * time in hours

If unit cost per hour = p

Hence,

C(n) = p * n

C(n) = pn

Answer:

for #1: the new price is $37.80 and the amount discounted was $7.20

Step-by-step explanation:

convert 16% to a decimal and multiply to find how much discounted then subtract that from the initial value

0.16*45= 7.20

45-7.20= 37.80

did u need the others too?

Answer:

$7.20

$0.636

$27.50

$53.3333333333

Step-by-step explanation:

16% × $45 = $7.20

8% × $7.95 = $0.636

$5.50 = 20%

20% × 5 = 100%

$5.50 × 5 = $27.50

$16 = 30%

30% × 3 and 1/3 = 100%

Answer:

You may not recognize this...but the base forms a "Pythagorean"  right triangle  with legs  of  6 and 8  cm

The area of a right triangle is  (1/2)  ( product of leg lengths)

So...the area of the base   = (1/2) (6 * 8 ) = (1/2) 48  = 24 cm^2

And the volume of the prism is just the   base area  x  height =   24  x  7  =   192 cm^2

Answer:

140.6 feet

Step-by-step explanation:

In ΔMNO, the measure of ∠O=90°, the measure of ∠N=62°, and NO = 66 feet. Find the length of MN to the nearest tenth of a foot.

Step 1

We have to find Angle M

Sum of angles in a triangle = 180°

M + N + O = 180°

M = 180° - ( N + O)

M = 180° - ( 90° + 62°)

M = 28°

Step 2

We find the length of MN

We solve using Sine rule

MN/sin O = NO/sin M

MN/sin 90 = 66/sin 28

Cross Multiply

MN = sin 90 × 66/sin 28

MN = 140.58 feet

Approximately = 140.6 feet

Answer:

Answer:

[tex]c(t) =-18t +212[/tex]

Step-by-step explanation:

Given

[tex](t_1,c_1) = (4,140)[/tex]

[tex](t_2,c_2) = (9,50)[/tex]

Required

Determine the equation

First, we calculate the slope (m)

[tex]m = \frac{c_2 - c_1}{t_2 - t_1}[/tex]

[tex]m = \frac{50 - 140}{9-4}[/tex]

[tex]m = \frac{-90}{5}[/tex]

[tex]m = -18[/tex]

The equation is then calculated as:

[tex]c =m(t - t_1) + c_1[/tex]

[tex]c =-18*(t - 4) + 140[/tex]

[tex]c =-18t +72 + 140[/tex]

[tex]c =-18t +212[/tex]

Hence, the function is:

[tex]c(t) =-18t +212[/tex]
