Answer: D

Step-by-step explanation:

1.88 in the equation is the rate of change.

rate of change means, "the speed at which a variable changes over a specific period of time."

L = the length of his femur. every time the femur grows an inch, the height also increases according to the equation.

an example is when the femur is 19 inches.

H = 1.88(19) + 32.01

H = 67.73

The height of the man is 67.72 inches if his femur was 19 inches.

Keith_Richards [23]

The number of hot dogs, x is 36 and hamburgers, y is 5 were sold

Step-by-step explanation:

Carlos ran a concession stand last Saturday and made $63.90 from

a total of 41 hot dogs and hamburgers. Each hot dog sold for $1.40

and each hamburger sold for $2.70

1. The number of hot dogs is x, and hamburgers is y

2. He made $63.90 from a total of 41 hot dogs and hamburgers

3. Each hot dog sold for $1.40 and each hamburger sold for $2.70

We need to find the number of hot dogs and hamburgers, that were sold

∵ The number of hot dogs is x, and hamburgers is y

∵ He sold 41 hot dogs and hamburgers

∴ x + y = 41 ⇒ (1)

∵ Each hot dog sold for $1.40 and each hamburger sold for $2.70

∵ He sold x hot dogs and y hamburgers

∵ He made $63.90 from sold them

∴ 1.4 x + 2.7 y = 63.9 ⇒ (2)

Let Us solve the system of equations to find x and y

Multiply equation (1) by -2.7 to eliminate y

∵ (-2.7)x + (-2.7)y = (-2.7)(41)

∴ -2.7 x - 2.7 y = -110.7 ⇒ (3)

- Add equations (2) and (3)

∴ -1.3 x = -46.8

- Divide both sides by -1.3

∴ x = 36

Substitute the value of x in equation (1) to find y

∵ x + y = 41 ⇒ (1)

∴ 36 + y = 41

- Subtract 36 from both sides

∴ y = 5

The number of hot dogs, x is 36 and hamburgers, y is 5 were sold

A tabletop in the shape of a trapezoid has an area of 5,658 square centimeters. Its longer base measures 119 centimeters, and th
Sedaia [141]
The formula for finding the area of a trapezoid is: sum of bases*height*1/2
By plugging in the information that we already have, we know: (119+65)*height*1/2=5658
184*1/2*height=5658
92*height=5658
height=61.5cm.

Check:
119+65=184
184*61.5=11316
11316*1/2=5658

MAXImum [283]

Answer:

1. A (85)(0.08)=6.90 then (85)(0.18)=15.30 then 85 + 6.90 + 15.30 =107.10

2. 82.68

Solving;

She was charged $65 before tax. She had to pay a 6% tax (65)(0.06)=3.90 then 65+3.90=68.90

After this she added 20% of the amount after tax rather 20% of 68.90

68.90(0.20)=13.78 then 68.90+13.78=82.68

Samantha is going to run in a 5K race. To prepare, she wants
user100 [1]

The number of minutes Samantha needs to run on Friday to reach her goal is 45 minutes.

<h3>Average</h3>

  • Monday = 45 minutes
  • Tuesday = 30 minutes
  • Wednesday = 55 minutes
  • Thursday = 25 minutes
  • Friday = x minutes

Average = (Monday + Tuesday + Wednesday + Thursday + Friday) / 5

40 = (45 + 30 + 55 + 25 + x) / 5

40 × 5 = 155 + x

200 = 155 + x

200 - 155 = x

45 = x

x = 45 minutes
