Answer:

(t,50-t) = \{(10,40),(20,30),(25,25)\}

Step-by-step explanation:

Given

Expression: 50 - t

Required

Evaluate when:

t = \{10,20,25\}

When t =10.

The expression is:

50 - t = 50 - 10

50 - t = 40

When t = 20

The expression is:

50 - t = 50 - 20

50 - t =30

When t = 25

The expression is:

50 - t = 50 - 25

50 - t =25

The result is:

(t,50-t) = \{(10,40),(20,30),(25,25)\}

The original price of a pair of shoes is $42. The sale price is 20% off the original price. What is the amount off the original
GREYUIT [131]

Answer:

a) What is the amount off the original price?

= $8.4

b) What is the new price for the pair of shoes?

= $33.6

Step-by-step explanation:

a) What is the amount off the original price?

We are told that:

The sale price is 20% off the original price.

Original price = $42

Hence:

$42 × 20%

$42 × 20/100

= $8.4

b) What is the new price for the pair of shoes?

The new price =

0riginal price - Amount off the original price

= $42 - $8.4

= $33.6

The original price = $33.6

Which explanation can be used to derive the formula for the circumference of a circle?
MrRa [10]
First, find the relationship of the circumference to its diameter by finding that the length of the diameter wraps around the length of the circumference approximately π times. Use this relationship to writing an equation showing the ratio of circumference to diameter equaling π. Then rearrange the equation to solve for the circumference. Substitute the diameter for 2 times the radius

HELP!!
WITCHER [35]

The sum of all interior angles of a triangle is 180° thus the measure of the exterior angle m∠K is 102° so option (B) is correct.

<h3>What is a triangle?</h3>

A triangle is a 3-sided shape that is occasionally referred to as a triangle. There are 3 sides and three angles in every triangle, some of which may be the same.

Triangle is a very common figure to deal with in our daily life.

It is known that the sum of all three angles inside a triangle will be 180°.

So,   m∠A +  m∠B +  m∠C = 180°

m∠C = 180° - 58° -  44°

m∠C = 78°.

The exterior angle of C = 180- 78 = 102°.

Hence "The sum of all interior angles of a triangle is 180° thus the measure of the exterior angle to m∠K is 102°".
