A shirt cost $21 last month. This month the price decreased by 30%. What is the new price?

Answers

Answer 1

Answer:

$14.70

Step-by-step explanation:

Find the 30% decrease:

21*0.3 = 6.3

Find new price:

21-6.3 = 14.7

Answer 2

Answer:

$14.7

Step-by-step explanation:

First, we need to convert the percentage to a decimal. 30% = .30

Now we multiply the price times the decimal, 21 x .30 = 6.3

We subtract this amount from the previous cost. 21 - 6.3= $14.7

Answers

Answer:

76.14 m

Step-by-step explanation:

create a proportion of height/shadow equals height/shadow

3.2/1.66 = h/39.5

cross-multiply:

1.66h = 39.5(3.2)

1.66h = 126.4

h = 76.14

Answers

Answer:

Solution given:

perpendicular distance =height [p]=40m

base or horizontal distance [b]=198m

Hypotenuse or zip line [h]=?

Now

By using Pythagoras law

h²=p²+b²

h²=40²+198²

h=√40804

h=202m

So the Zip line is 202m long.

the diagram shows a parallelogram. work out the value of x​

Answers

Answer:

x = 39

Step-by-step explanation:

The opposite angles of a parallelogram are congruent, so

3x - 15 = 2x + 24 ( subtract 2x from both sides )

x - 15 = 24 ( add 15 to both sides )

x = 39

The value of x from the parallelogram is given by the equation x = 39°

What is a Parallelogram?

A parallelogram is a simple quadrilateral with two pairs of parallel sides. The opposite or facing sides of a parallelogram are of equal length and the opposite angles of a parallelogram are of equal measure

The four types are parallelograms, squares, rectangles, and rhombuses

Properties of Parallelogram

Opposite sides are parallel

Opposite sides are congruent

Opposite angles are congruent.

Same-Side interior angles (consecutive angles) are supplementary

Each diagonal of a parallelogram separates it into two congruent triangles

The diagonals of a parallelogram bisect each other

Given data ,

Let the parallelogram be represented as ABCD

Now , the total internal angle of a parallelogram is 360°

Now , the equation will be

∠A + ∠B + ∠C + ∠D = 360°

Substituting the values in the equation , we get

3x - 15 + 2x + 2x + 2x + 24 = 360°   be equation (1)

On simplifying the equation , we get

9x + 9 = 360

Subtracting 9 on both sides of the equation , we get

9x = 351

Divide by 9 on both sides of the equation , we get

x = 39°

Therefore , the value of x is 39°

Hence , the equation is x = 39°

if a cheetah jumps 7 meters how many centimeters did the animal jump
help pls and explain

Answers

Answer: 700 cm

=============================================

Explanation:

To convert from meters to cm, you multiply by 100. This is because there are 100 cm in one meter.

You can write it out like this

1 m = 100 cm

7*(1 m) = 7*(100 cm) .... multiplying both sides by 7

7 m = 700 cm

Note: 7 meters = 22.97 feet approximately

If a cheetah jumps 7 meters then the animal will jump 700 centimeters.

How do you convert meters into centimeters?

One meter is equal to 100 times centimeters. To convert meters into centimeters multiply the factor by 100 centimeters.

To convert meters into cm, we will multiply by 100. This is because there is 100 cm in one meter.

We know that,

1 m = 100 cm

For 7 m

= 7 x (100 cm)

= 700 cm
