Answer:

12 ft

Step-by-step explanation:

Since the doors are similar then the ratios of corresponding dimensions are equal.

let x be the height of the bigger door, then

[tex]\frac{small}{big}[/tex] : [tex]\frac{3}{x}[/tex] = [tex]\frac{2}{8}[/tex] ( cross- multiply )

2x = 24 ( divide both sides by 2 )

x = 12

Height of the bigger door is 12 ft

no

Step-by-step explanation:

A right triangle has a formula a^2+b^2=c^2 with c being the longest side (hyponotuse). 10 squared is 100, 11 squared is 121, so add those and get 221. 14 squared is only 196 which is not equal to 221 so it is not a right triangle

Answer:

Yes

Answer:

$42.14

Step-by-step explanation:

Given data

Cost of meal= $98

tax= 9%

Tip= 20%

Let us find the amount of the tax and the tip

Tax

=9/100*98

=0.09*98

=$8.82

Tip

=20/100*98

=0.2*98

=$19.6

Hence the total amount paid is

=98+8.82+19.6

=126.42

The amount paid by Pryia

=126.42/3

=$42.14

Answer:

80

Step-by-step explanation:

f(3)=4(3)^3-3(3)^2+5(3)-16

f(3)=4(3*3*3)-3(3*3)+15-16

f(3)=4(27)-3(9)+15-16

f(3)=108-27+15-16

f(3)=81+15-16

f(3)=96-16

f(3)=80

Step-by-step explanation:

subtract the areas of a circle from the area of a square and divide by 4

A_square = L x W

A_circle = pi x r^2

L, W= 12cm

r= 12/2cm

(A_square - A_circle) / 4

divide by 4 since the remaining portions are symmetrical

Answer:

I'm sorry I don't know the answer to it

Answer:

Step-by-step explanation:

How many questions are on the exam?  Represent this by n.

Then 40% of n comes out to 12 questions, or more symbolically,

               0.40n = 12, after which we get n = 12/0.40 = 30

Answers:

(1)  0.40n = 12 is the desired equation.

(2) n = 30 is the number of questions on the exam.

(3) See above for explanations.

Answer:

4.118 * 10^6

Step-by-step explanation:

When you multiply exponents, you just add the exponents together, so 10^2 * 10^3 is 10^5. Then you just multiply the 7.1 and the 5.8, which is 41.18. However, scientific notation should have only 1 digit above the decimal spot, so you make the number smaller from 41.18 to 4.118, so you add 1 exponent to the 10^5.

41.18*10^5 = 4,118*10^6

(EDIT, THE GUY WHO COMMENTED IS CORRECT, SCIENTIFIC NOTATION IS WHEN THE DIGIT IS GREATER THAN 1 OR LESS THAN 10, SO IT WOULD BE 4.118*10^6)

Answer:

411.8 · [tex]10^{4}[/tex]

Step-by-step explanation:

7.1 · 10³ × 5.8 · 10²

7.1 × 5.8 = 41.18

10³ + 10² = [tex]10^{5}[/tex]

41.18 · [tex]10^{5}[/tex]

Scientific notation can only have one digit after the decimal.

411.8 · [tex]10^{4}[/tex]

Answer: $8.91

Step-by-step explanation:

Answer:

the answer is 48 your welcome

(2^2)^4 = 256

3^4 = 81

256 × 81 = 20735

27 × 16 = 432

20735÷432 = 47.99

round to 47.99 to the nearest 10th and you will get 48.

Lol

Final answer : 48

120.

Trust me.  It is correct using a formula.

Answer:

The cost of admission

Step-by-step explanation:

Noelle only has to pay once for admission and buy multiple tickets for each ride.

Answer:

Ratio = 3:2:1

Let the Values be 3x:2x:x

3x+2x+x=180

=> 6x=180

=> x =180/6

=> x = 30

3×30=90

2×30=60

1×30=30

Answer:

x = 3±√5

Step-by-step explanation:

Given the quadratic equation;

0 = x² – 6x + 4

Swap sides

x² – 6x + 4=  0

Subtract 4 from both sides

x² – 6x + 4 - 4=  0 - 4

x² – 6x = -4

Complete the square;

Add the square of half of coefficient of x to both sides

Coefficient of x = -6

Half of Coefficient  of x = -6/2 = -3

square of the half of Coefficient of x = (-3)²

Add (-3)² to both sides

x² – 6x + (-3)² = -4 + (-3)²

(x-3)² = -4 + 9

(x-3)² = 5

Take the square root of both sides

x - 3 = ±√5

x = 3±√5

This gives the solution to the equation

Answer: Quadrant c

So the anwser is C. III

Answer:

the quadrant in which the terminal side of each angle lies

-250 lies is B II quadrant.

Answer:

b = -6

Step-by-step explanation:

14.4 = -2.4b (swap the sides of the equation)

-2.4b = 14.4 (divide both sides of the equation by -2.4)

b = -6

Answer:

2 and a half hours

Step-by-step explanation:

since it takes 30 min to calibrate, and she did it 5 times, that is 5x30 which is 150 minutes, 150 minutes is 2 and a half hours

Answer:

Step-by-step explanation:

6 - 3x = -15

Move all terms not containing x to the right side:

-3x = -15-6

-3x = -21

Solve for x by dividing -21 by -3

You got this!

Answer:

x = 2

Step-by-step explanation:

7x−5=2x+5

step 1 add 5 to each side

-5 + 5 = cancels out

5 + 5 = 10

we now have 7x = 2x + 10

step 2 subtract 2x from each side

2x - 2x cancels out

7x - 2x = 5x

we now have 10 = 5x

step 3 divide each side by 5

5x / 5 = x

10 / 5 = 2

we' re left with x = 2
