Help. What Is The Length Of EF In The Right Triangle Below.

Answers

Answer 1

Answer:

A

Step-by-step explanation:

Since the triangle is right use Pythagoras' identity to find EF

The square on the hypotenuse is equal to the sum of the squares on the other two sides, that is

EF² + DF² = DE² ← substitute values

EF² + 12² = 18², that is

EF² + 144 = 324 ( subtract 144 from both sides )

EF² = 180 ( take the square root of both sides )

EF =  → A

Answer 2
Wish you luck on that

Solve the equation for m. Show your work on the canvas. Move -n by using opposite operation. Then just write the equation as is. This is a one step equation. 4=m−n

Answers

Answer:

m = 4+n

Step-by-step explanation:

Given the expression 4 = m-n, we are to make m the subject of the formula

From the equation

4 = m-n

Rearrange

m-n = 4

Add n both sides of the equation

m-n+n = 4+n

m+0 =4+n

m = 4+n

Hence the expression for m is given as m = 4+n

Answers

Answer:

Total area ≈ 0.082 ​

Step-by-step explanation:

Round answers to three decimal places.

Area of 1st rectangle = 0.032

Area of 2nd rectangle =25 x 0.000863

= 0.022

Area of 3rd rectangle = 0.014

Area of 4th rectangle = 0.008

Area of 5th rectangle = 0.004

Area of 6th rectangle = 0.002

Total area = 0.082 ​

Rounding up to 3 decimal places: this means 3 numbers after the decimal point

Area of 1st rectangle ≈ 0.032

Area of 2nd rectangle ≈ 0.022

Area of 3rd rectangle ≈ 0.014

Area of 4th rectangle ≈ 0.008

Area of 5th rectangle ≈ 0.004

Area of 6th rectangle ≈ 0.002

Total area = 0.032 + 0.022 + 0.014 + 0.008 + 0.004 + 0.002

= 0.082

Total area ≈ 0.082 ​

Answer:

Round answers to three decimal places.

Area of 1st rectangle =0.022

Area of 2nd rectangle =  

⇒ 0.014

Area of 3rd rectangle =

Find the values of x and y.

Answers

Answer:

x=30° y=5

Step-by-step explanation:

All sides of the top triangle are equal. And all angles are equal Since it's an equilateral triangle.

so

8y=40

y=40/8

y=5

Since it's an equilateral triangle. All angles are equal And each angle has dimensions

=180°/3=60°

The angle of the straight line = 180°

so The obtuse angle of the lower isosceles triangle is 180°-60°=120°

The angles at the base of the isosceles triangle are equal

so 2x° = 180°-120°

2x°=60°

x°=60°/2

x°=30°

Answers

Answer:

612

Step-by-step explanation:

To find this answer, you can invert the equation:

452.88 = 0.74x

x = 452.88 / 0.74

x = 612

The number 452.88 is 74% percentage of the number 612.

What is Percentage?

percentage, a relative value indicating hundredth parts of any quantity.

We have to find the number of 452.88 is 74%

Let x be the number

74/100×x=452.88

74x/100 = 452.88

Multiply both sides by 100

74x=45288

Divide both sides by 74

x=45288/74

x=612

Hence, 452.88 is 74% of the number 612.

Your factory installed tires have a comfort that 95 inches if the odometer reading reading is 32,000 miles on your car you have tires with a conference have 103 inches how many miles have you actually traveled

Answers

Answer:

The correct solution is "35440.8".

Step-by-step explanation:

The given values are:

Bigger tire's circumference,

= 103 inches

Factor installed tire's circumference,

= 95 inches

Odometer reading,

= 32,000 miles

As we know,

⇒ [tex]Actual \ distance = K\times odometer \ reading[/tex]

Where,

⇒ [tex]K = \frac{Bigger \ tier \ circumference}{Factor \ installed \ tier \ circumference}[/tex]

i.e.,

⇒ [tex]K=\frac{103}{95}[/tex]

On applying the formula,

⇒ [tex]Actual \ distance \ travelled=\frac{103}{93}\times 32,000[/tex]
