Need help on this question

Answer:

392

Step-by-step explanation:

V= length x width x height.

V= 14cm×14cm×2cm

V= 392cm^3

Find the volume of the rectangular prism.

Length = 14 cm

Width = 14 cm

Height = 2 cm

Volume = ?

Substituting the values given, in the formula, We get,

⇒ Volume of rectangular prism = 14 × 14 × 2

⇒ Volume of rectangular prism = 392 cm³

The Volume of the rectangular prism is 392 cm³

Answer: $8.91

Step-by-step explanation:

Answer: 12 cm = x

Answer:

5/13

Step-by-step explanation:

Sin = Opposite/hypotenuse

SinA = 5/13

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:

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:

I think i gave u answer for 21 and 23 but ill give ya again :)

21.) x = 0

22.) x = 8

23.) x = 0

24.) x = 12

Step-by-step explanation:

21.) x + 12 = 12

=> x = 0

22.) x - 1 = 7

=> x = 8

23.) 12 + 2x = x + 12

=> 12 + x = 12

=> x = 0

24.) 2x - 14 = 10

=> 2x = 24

=> x = 12

(All of these equations are set equal to their opposite side on the same figure since both the sides are parallel and congruent)

Hope this helps!

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:

Forth term of the sequence is 61

Step-by-step explanation:

Let's just go from a1 to a4:

a1 = 5

a2 = 2x5+3 = 13

a3 = 2x13+3 = 29

a4 = 2x29+3 = 61

Answer: 56.57

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

Answer:

48 oz

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:

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

Answer:

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

Yes

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:

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

it's twelve you're welcome

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
