Answer: 2521.91 ft^3

Step-by-step explanation:

Answer:

Step-by-step explanation:

Using the cylinder volume formula, V = (pi)r^2h

Since the radius and the height have already been given, no further calculations are necessary.

V= (pi)(6.5)^2(19)

V=(3.14)(42.25)(19)

2520.635 ft^3

Answer: Velocity

=

Displacement

Time

Explanation:

75 km = 75000 m

1.5 hours = 5400 sec

Applying the formula

Velocity

=

75000 m

5400 s

=

13.89 m/s

Step-by-step explanation:

Answer:

Speed= 50 km/h

Step-by-step explanation:

S=d/t

s=75km/1.5h

s=50km/h

To find these out you have to use the strategy of P (parenthesis) E (exponents) M (multiplication) D (division) A (addition) S (subtraction)

3 - 4 x 2 The first thing you need to do is do the multiplication part first, since subtraction is the last thing you need to do. You multiply 4 and 2 and get the answer of 8, then subtract 3 which is 5

5 x 3 - 4 The first thing you need to do is multiplication 5 x 3 which equals 15 and then do 15 - 4 = 11

15 ÷ (3 x 5) x 2 The first thing you do is you do the P (parenthesis) which is (3x5) which equals 15. Then you multiply 15 with 2 which is 30 and then divide 30 with 15 which is 2

5 + 3 x 2 ÷ 6 First you need to do the Multiplication which is 3 x 2 which equals 6, and then you do the division, which is 6 ÷ 6 which is 1. Then add 5 to the 1 which is 6.

Answer:

a>1/2

Step-by-step explanation:

1/3a>(2/3)-(1/2)=

1/3a>(1/6)=

a>1/2

Answer:

x>9

Step-by-step explanation:

Answer:

x > 9

Step-by-step explanation:

Simply solve for x.

What we have to do is subtract 3 from both sides, then divide by 5 to both sides.

5x > 45

x > 9

x is greater than 9.

Answer: 12s+27j≤450

Step-by-step explanation:

From the question, we are informed that Jackie has a maximum of $450 to spend on shirts and jeans and that the shirts she wants to buy are $12 each, including tax while the jeans she wants to buy are $27 each, including tax.

The inequality that represents all possible combinations of s, the number of shirts, and j, pairs of jeans, Jackie can buy will be:

= 12s+27j≤450

Answer: $750

Step-by-step explanation:

We can solve this using direct proportion.

Let the number of minutes used be x

Let the cost be y

For direct proportion,y = kx

where, y = 250, x = 30

y = kx

250 = 30k

k = 250/30

k = 8.33

The cost to make a 90 minute movie will be:

y = kx

where,

y = unknown

k = 8.33

x = 90

y = 90 × 8.33

y = $750

The cost to make a 90 minute movie is $750.

Answer:

The y intercept it 0 hours and 44

In this model y intercept represnts the lowest possible score obtainable due to lowest study.

The slope shows there is a direct correlation as x increases so does the value of y so it has a positive slope. All it represents is the more they studied the higher they score

Answer:

  yes

Step-by-step explanation:

The width of the rectangle is given by ...

  W = A/L

  W = (20 cm²)/(8 cm) = 2.5 cm

__

The modified rectangle has a length of (8 cm +2 cm) = 10 cm, and an area of (20 cm² +4 cm²) = 24 cm². Its width will be ...

  W = (24 cm²)/(10 cm) = 2.4 cm

The percentage change in size is ...

  ((2.4 cm)/(2.5 cm) -1) × 100% = -4%

The width of the rectangle decreased less than 5%. Noah is correct.

Answer:

That is literally still the same formula for mean.

Answer:

The equation in point-slope form of the line is:

[tex]y-\left(-5\right)=\frac{7}{4}\left(x-\left(-1\right)\right)[/tex]

Step-by-step explanation:

Given the points

[tex]\mathrm{Slope\:between\:two\:points}:\quad \mathrm{Slope}=\frac{y_2-y_1}{x_2-x_1}[/tex]

[tex]\left(x_1,\:y_1\right)=\left(-1,\:-5\right),\:\left(x_2,\:y_2\right)=\left(3,\:2\right)[/tex]

[tex]m=\frac{2-\left(-5\right)}{3-\left(-1\right)}[/tex]

[tex]m=\frac{7}{4}[/tex]

As the point-slope form is defined as

[tex]y-y_1=m\left(x-x_1\right)[/tex]

where m is the slope.

substituting the values m=7/4 and the first point (-1, -5)

[tex]y-\left(-5\right)=\frac{7}{4}\left(x-\left(-1\right)\right)[/tex]

Therefore, the equation in point-slope form of the line is:

[tex]y-\left(-5\right)=\frac{7}{4}\left(x-\left(-1\right)\right)[/tex]

Answer:

Find the LCM of 2 and 3:

LCM = 2 x 3 = 6

Multiply the ratio by 6:

Ratio = 1/2 x 6 : 1/3 x 6

Ratio = 3 : 2

Answer: all the -2's are the least and then it's all the postive 2's. After that it should be the 3's then the 4's for the greatest
