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:its either 7:20 or 8:00 i think

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:

[tex]\frac{100}{130321}[/tex]

Step-by-step explanation:

10² ÷ [tex]19^{4}[/tex]

100 ÷ [tex]19^{4}[/tex]

100 ÷ 130321

[tex]\frac{100}{130321}[/tex]

Answer: $8.91

Step-by-step explanation:

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:

1: 18.75

Step-by-step explanation:

We multiply both sides by 5.

Answer: 12 cm = x

Step-by-step explanation:

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:

Step-by-step explanation:

c = πd

75 = 3.14d

Divide both sides by 3.14

23.89 = d

24 inches

Answer:

[tex]\boxed {\boxed {\sf 24 \ inches}}}[/tex]

Step-by-step explanation:

We want to find the diameter of the tire given the distance traveled in 1 full rotation.

The circumference of a circle is the distance all the way around. If a wheel or tire makes 1 full rotation, the distance traveled is equal to the circumference.

The circumference is the product of pi and the diameter.

[tex]c=\pi \times d[/tex]

We know the circumference (distance traveled in 1 full rotation) is 75 inches. We can substitute this value for c.

[tex]75 \ in =\pi \times d[/tex]

We want to find the diameter, so the variable must be isolated. It is being multiplied by pi. The inverse of multiplication is division, so we divide both sides by pi.

[tex]\frac {75 \ in}{\pi}= \frac{\pi \times d}{\pi}[/tex]

[tex]\frac {75 \ in}{\pi}=d[/tex]

[tex]23.8732415 \ in=d[/tex]

Round to the nearest inch. The 8 in the tenths place tells us to round the 3 up to a 4.

[tex]24 \ in \approx d[/tex]

The diameter of the tire is approximately 24 inches.

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

Answer: 56.57

HOPE THIS HELPS

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:

Step-by-step explanation:

The identity element for addition of rational numbers

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

because it is correct

Answer:

Step-by-step explanation:

maybe a ?

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
