The height of an object is directly proportional to the length of its shadow a tree that is 2.5 meters tall cast a shadow 5 meters long how tall is a building that cast a shadow 78 meters long

Answers

Answer 1

Answer:

The height of the building that casts a shadow of 78m meters is 39m

Step-by-step explanation:

Let height be represented by H and the shadow is S

as they are directly proportional

H [tex]\alpha[/tex] s

H=KS   ( where K is a proportionality constant)

H=2.5m , S= 5m

On substituting in the equation

2.5 = K*5

K= 0.5

Now the equation becomes

H = 0.5*S

Height when shadow is 78m

H= 0.5*78

H= 39m

How many candy bars must be sold to make a profit of $700?

Answers

Answer:800

Step-by-step explanation:

I'm assuming (P) represents profit

Apply out 700 in the equation

700=1.50n-500

Add 500 to each side

1200=1.50n

Divide each side by 1.50

800=n.

800 bars must be sold

800 candy bars must be sold to make a profit of $700.

What is an equation?

An equation is written in the form of variables and constants separated by the operation of multiplication and division,

An equation states that terms in different forms on both sides of the equality sign are equal.

Multiplication and division do not separate the terms of an equation.

Given, p = 1.50n - 500, assuming no. of candy bars to be n and we had a profit of $700.

∴ No. of candy bars sold to make a profit of $700 is,

700 = 1.50n - 500.

700 + 500 = 1.50n.

1.50n = 1200.

n = 1200/1.50.

n = 800 candy bars.

Divide both sides by 55.

Take the square root of both sides.

A sales agent makes 40 calls a day. About 15% he calls result in a sale. How many days
will it take for the sales agent to meet a quota of 120 sales?

Answers

Answer: 20 days

Step-by-step explanation:

Since the sale agent makes 40 calls a day and about 15% he calls result in a sale. This means the number of sales will be:

= 15% × 40

= 0.15 × 40

= 6

6 sales out of every 40 calls per day.

The number of calls to make 120 sales will be:

= 15% of x = 120

0.15 × x = 120

0.15x = 120

x = 120/0.15

x = 800 calls

Since he needs 800 calls and he makes 40 calls per day, the number of days needed will be:

= 800/40

= 20 days
