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

A) x = 15

steps:

90 = 5x + 15

-15 -15

75 = 5x

÷5 ÷5

15 = x

explanation:

< P is 90°

so you have the equation of < P equal 90 to find the x

B) < RQP = 33

steps:

2x + 3

2(15) + 3

30 + 3

33

explanation:

now that you know what x equals you just plug in 15 for the x and solve

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

Answer:

x=-13

Step-by-step explanation:

-4+4x=-56

add 4 on both sides

4x=-52

divide 4 on both sides

x=-13

Answer:

x=-13

Step-by-step explanation:

-4 + 4x = -56

+4. +4

4x = -52

÷4. ÷4

x = -13

Step-by-step explanation:

Answer:

90 degrees

Step-by-step explanation:

Answer:

x = 12

Step-by-step explanation:

This is a supplementary angle so the right side is equal to 90°. This means the other side must also equal 90°

So subtract 20° from 90° and you get 70°

Next you can just (6(12)-2) or continuously substitute until you get the right answer.

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°

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°

Answer:

[tex]\sqrt{10}[/tex]/10

Step-by-step explanation:

cos is adjacent side/hypotenuse

you need to find the hypotenuse

Let h = length of hypotenuse

[tex]6^{2} + 18^{2} = h^{2}[/tex]

[tex]h^{2}[/tex] = 36 + 324 = 360

h = [tex]\sqrt{360}[/tex] = 6[tex]\sqrt{10}[/tex]

cos (theta) = 6/6[tex]\sqrt{10}[/tex] = 1/[tex]\sqrt{10}[/tex] = [tex]\sqrt{10}[/tex]/10

Step-by-step explanation:

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.

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

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.

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
