Answer:

here you go

Step-by-step explanation:

The converse of the Pythagorean Theorem tells us that by comparing the sum of the squares of two sides of a triangle to the square of its third side, we can determine whether that triangle is an acute, right, or obtuse.

To determine from the side lengths if a triangle is a right triangle. Therefore, the correct answer is option C.

The Pythagoras theorem which is also referred to as the Pythagorean theorem explains the relationship between the three sides of a right-angled triangle. According to the Pythagoras theorem, the square of the hypotenuse is equal to the sum of the squares of the other two sides of a triangle.

The converse of Pythagoras theorem states that “If the square of a side is equal to the sum of the square of the other two sides, then triangle must be right angle triangle”.

By comparing the sum of the squares of two sides of a triangle to the square of its third side, we can determine whether that triangle is an acute, right, or obtuse.

Therefore, option C is the correct answer.

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

1 hours → 75 miles

? hours → (1125/75)

It takes her 15 hours to drive 1125 miles.

Answer:

15 hours

Step-by-step explanation:

Finding how much distance in 1 hour

⇒ Ceci = 225 miles = 3 hours

⇒ 225 miles = 3 hours

⇒ 225/3 miles = 3/3 hours

⇒ (25 x 9)/3 miles = 1 hour

⇒ (25 x 3) miles = 1 hour

⇒ 75 miles = 1 hour

Finding how much hours in 1125 miles

⇒ 75 miles = 1 hour

⇒ 75x miles = 1125 miles = x hours

⇒ 75x/75 = 1125/75

⇒ x = 15

⇒ 75(15) miles = 1125 miles = (15) hours

⇒ 1125 miles = (15) hours

Answer:

A. 1 : 36

B. 1 : 54

Step-by-step explanation:

1 feet = 12 inches

A.

rasio = scaled length : actual length

        = 6 inches : 18 feet

        = 6 inches : (12 × 18) inches

        = 6 : 216 ⇒ omit the units when both units are the same

        = 1 : 36

B.

rasio = scaled length : actual length

        = 4 inches : 18 feet

        = 4 inches : (12 × 18) inches

        = 4 : 216 ⇒ omit the units when both units are the same

        = 1 : 54

Answer:

4:7

Step-by-step explanation:

Answer:

Radius: about 1.42 mm

Step-by-step explanation:

First, you divide the circumference (8.9) by 3.14, or π.

Cirucmference(8.9) divided by π(3.14) = the diameter (2.83439490446)

Diameter (2.83439490446) divided by 2 = radius (1.41719745223)

Now, you have to round to the nearest hundredth.

1.41719745223 rounded to the nearest hundredth is 1.42 because the second number after the decimal is your hundredths place. If the number after the decimal is 4 or less, just remove all of the digits to the right. If it's five or more, like this case where it is 7, you add 1 to the hundredths place, then you remove all of the digits to the right.

supplementary angles are when two angles sum up to 180 degrees.

∠x and ∠y are supplementary angles

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

Answer:

64°

Step-by-step explanation:

Supplementary angles are two angles that add up to 180°.

∠x + ∠y = 180° <== substitute 116° for ∠y

∠x + 116° = 180° <== subtract 116 from both sides

     - 116    - 116

∠x = 64° <== measure of ∠x

Therefore, the measure of ∠x is 64°

→ [tex]x=-8[/tex]

Step-by-step explanation:

Given: [tex]\frac{-72}{x} = 9[/tex]

[tex]\frac{-72}{x} = 9[/tex]

Step 1: Multiply all terms by the same value to eliminate fraction denominators.

[tex]\frac{-72}{x} = 9[/tex]

⇒ [tex]x * \frac{-72}{x} = x * 9[/tex]

Step 2: Cancel multiplied terms that are in the denominator.

[tex]x * \frac{-72}{x} = x * 9[/tex]

⇒ [tex]-72 = x * 9[/tex]

Step 3: Re-order terms so constants are on the left.

[tex]-72 = x * 9[/tex]

⇒ [tex]-72 = 9x[/tex]

Step 4: Divide both sides by the same factor.

[tex]-72 = 9x[/tex]

⇒ [tex]\frac{-72}{9} = \frac{9x}{9}[/tex]

Step 5: Simplify.

[tex]\frac{-72}{9} = \frac{9x}{9}[/tex]

⇒ [tex]-8 = \frac{9x}{9}[/tex]

[tex]-8 = \frac{9x}{9}[/tex]

⇒ [tex]-8 = x[/tex]

[tex]-8x = x[/tex]

⇒ [tex]x = -8[/tex]

Hence, [tex]x = -8[/tex] is your answer.

How to solve:

     By finding the perimeter of the fence in feet, we can check that value against the 4 proportion options listed in the problem. Whichever is true will be the correct answer.

Perimeter - in feet

Where P is perimeter in miles, x is perimeter in feet, w is width in miles, and L is length in miles.

Set up equation                                                     P = 2w + 2L

Substitute                                                               P = 2(1/8) + 2(1/4)

Simplify                                                                   P = 2/8 + 2/4

Common denominator                                          P = 1/4 + 2/4

Simplify                                                                   P = 3/4 mi.

Translate                                                                x = (3/4)*5280

Simplify                                                                   x = 3960 ft.

For the following: Where m represents the mile unit, f represents the foot unit, and x represents the number of feet of fencing.

First option

Set up equation                                            (3/4)m/x = m/5280f        

Equal variables                                         16[(3/4)m/x) = 12[m/5280f]

Simplify                                                             12m/16x = 12m/63360f

Remove miles                                                          16x = 63360f

Isolate x variable                                                    /16     /16

Solution                                                                       x = 3960 ft.

Second Option

Set up equation                                             (3/8)m/x = m/5280f

Equal variables                                         64[(3/8)m/x] = 24[m/5280f]

Simplify                                                              24m/64x = 24m/126720f

Remove miles                                                            64x = 126720f

Isolate x variable                                                      /64     /64

Solution                                                                          x = 1980 ft.

Third Option

Set up equation                                               x/(3/4)f = m/5280f

Equal variables                                      7040[x/(3/4)f] = m/5280f

Simplify                                                   7040x/5280f = m/5280f

Remove feet                                           7040x = m

Translate                                                 7040x = 5280f

Isolate x variable                                   /7040     /7040

Solution                                                           x = (3/4)f

Fourth Option

Set up equation                                             x/(3/8)f = m/5280f

Equal variables                                  14080[x/(3/8)f] = m/5280f

Simplify                                               14080x/5280f = m/5280f

Remove feet                                        14080x = m

Translate                                              14080x = 5280f

Isolate x variable                                /14080     /14080

Solution                                                         x = 3/8f

Check:

If the perimeter of the fence, in feet, is the first option, then when

x = 3960, the number of miles and feet should be equal. Let's test this.

(3/4)m/x = 1

(3/4)m/3960f = 1

(3/4)(5280f)/3960f = 1

3960f/3960f = 1

1 = 1

Therefore, option 1 is correct.

$0.50/muffin

Step-by-step explanation:

To find the unit rate we have to find out how much 1 muffin costs:

To do this we can divide both sides by 7:

7÷7 for 3.50÷7

1 muffin for 0.50

Therefore our answer is $0.50/muffin

Answer:

$0.50 / muffin

Step-by-step explanation:

7 muffins for $3.50

To find the unit rate, we need to find what 1 muffin costs.

so

1 muffin = 3.5/7 = 0.5

$0.50 per muffin.

By definition of vertically opposite angle, the value of x is,

⇒ x = 42

An angle is a combination of two rays (half-lines) with a common endpoint. The latter is known as the vertex of the angle and the rays as the sides, sometimes as the legs and sometimes the arms of the angle.

We have to given that;

Angles S and T are vertical angles.

And, The angle S has a measure of (x - 2)°, and angle T has a measure of 40°.

Now, We know that;

Vertically opposite angles are equal to each other.

Hence, We get;

⇒ ∠ S = ∠ T

⇒ (x - 2)° = 40°

⇒ x - 2 = 40

⇒ x = 40 + 2

⇒ x = 42

Thus, By definition of vertically opposite angle, the value of x is,

⇒ x = 42

Answer:

A is 1 in 100 and b is 1 in 25

Step-by-step explanation:

there are 10 digits (1, 2, 3, 4, 5 ,6 ,7 ,8 ,9, 0).

that gives you a 1 in 10 chance but there are 2 and to get both of them, you do 1 in 10 x 1 in 10 which is 1 in 100. if you know that they are both even, this limits it to a 1 in 5 twice, 1 in 5 x 1 in 5 is 1 in 25.
