Answer:

V = 75 pi

Step-by-step explanation:

We know the volume of a cylinder is given by

V = pi r^2 h where r is the radius and h is the height

V = pi ( 5)^2 (3)

V = pi (25)(3)

V = 75 pi

===============================================

Work Shown:

r = 5 is the radius

h = 3 is the height

V = pi*r^2*h .... volume of a cylinder

V = pi*5^2*3

V = pi*25*3

V = pi*75

V = 75pi ..... exact volume in terms of pi

V = 75*3.14

V = 235.5

If you used the approximation pi = 3.14, then the approximate volume is about 235.5 cubic units. Use more decimal digits of pi to get a more accurate answer.

Note how the pi*r^2 portion represents the area of the circular base. So we can say

volume = (area of base)*(height)

Answer:

Scientific Notation: 3754 × [tex]10^{-4}[/tex]

Step-by-step explanation:

Have a great summer :)

Answer:

3.754 • 10^-4

Step-by-step explanation:

Put decimal point back until in front of a whole number( not zero ;D). So it would be 3.754 and since it was going left or backwards the exponent would be negative. Therefore, giving our answer!

Hope this helped, good luck! :)

Answer:

Around 376.99

Step-by-step explanation:

the formula is 2πrh+2πr²

so if we plug in everything we get 2π(4)(11)+2π(4)²

When we simplify that, we would get 376.99

Given:

Area of a rectangle = [tex]x^3-5x^2+3x-15[/tex]

Width of rectangle = [tex]x^2+3[/tex]

To find:

The length of the rectangle.

Solution:

The area of a rectangle is:

[tex]A=l\times w[/tex]

Where, l is length and w is the width.

It is can be written as:

[tex]\dfrac{A}{w}=l[/tex]

[tex]l=\dfrac{A}{w}[/tex]

Putting [tex]A=x^3-5x^2+3x-15[/tex] and [tex]w=x^2+3[/tex], we get

[tex]l=\dfrac{x^3-5x^2+3x-15}{x^2+3}[/tex]

[tex]l=\dfrac{x^2(x-5)+3(x-5)}{x^2+3}[/tex]

[tex]l=\dfrac{(x^2+3)(x-5)}{x^2+3}[/tex]

[tex]l=x-5[/tex]

Therefore, the length of the rectangle is [tex]x-5[/tex].

Answer:

$669

Step-by-step explanation:

Given data

Principal= $500

Rate= 6%

Time= 5 years

The compound interest formula is given as

A= P(1+r)^t

A=500(1+0.06)^5

A=500(1.06)^5

A=500*1.338

A=$669

Answer:

The degree of the polynomial ≈ 4

Step-by-step explanation:

The degree of a polynomial, is given by the highest value of the sum of the exponents (powers) of the of the variables (monomials) that are present in the polynomial expression

The given polynomial expression is x²·y² + y³ + 4

The sum of the exponents; 2 + 2 = 4, and 3

The sum of exponents 4 > 3

Therefore, the degree of the polynomial = 4.

Answer: $9,240

Step-by-step explanation:

If the car was sold at 40% off,

That is 40/100=0.4

selling price=$6600

So, 40% of $6600= 0.4*$6600=$2640

this means that the seller deducted this amount from his cost price to sell it to you.

Therefore,original price he bought will be a sum of both,that is

the amount he sold to you + the amount he deducted =$6600+$2640=$9,240.

Therefore the original price is $9,240

hope it’s correct !

Answer:

(40/100) × X = 6600

X = (6600×100)/40

Equations

(1)

[tex]x - y = 25[/tex]

[tex]2x + 3y = 180[/tex]  

(2)

[tex]2x - 3y = -5[/tex]

[tex]11x + y = 550[/tex]  

(3)

[tex]x - y = 19[/tex]

[tex]-12x + y = 168[/tex]

Solutions

[tex](-17,-36)[/tex]

[tex](47, 33)[/tex]

[tex](51, 26)[/tex]

Required

Match equations with solutions

(1) [tex]x - y = 25[/tex] and [tex]2x + 3y = 180[/tex]

Make x the subject in: [tex]x - y = 25[/tex]

[tex]x = 25 + y[/tex]

Substitute [tex]x = 25 + y[/tex] in [tex]2x + 3y = 180[/tex]

[tex]2(25 + y) + 3y = 180[/tex]

[tex]50 + 2y + 3y = 180[/tex]

[tex]50 + 5y = 180[/tex]

Collect like terms

[tex]5y = 180-50[/tex]

[tex]5y = 130[/tex]

Solve for y

[tex]y =26[/tex]

Recall that: [tex]x = 25 + y[/tex]

[tex]x = 25 + 26[/tex]

[tex]x = 51[/tex]

So:

[tex](x,y) = (51,26)[/tex]

(2)  [tex]2x - 3y = -5[/tex] and [tex]11x + y = 550[/tex]

Make y the subject in [tex]11x + y = 550[/tex]

[tex]y = 550 - 11x[/tex]

Substitute [tex]y = 550 - 11x[/tex] in [tex]2x - 3y = -5[/tex]

[tex]2x - 3(550 - 11x) = -5[/tex]

[tex]2x - 1650 + 33x = -5[/tex]

Collect like terms

[tex]2x + 33x = -5+1650[/tex]

[tex]35x = 1645[/tex]

Solve for x

[tex]x = 47[/tex]

Solve for y in [tex]y = 550 - 11x[/tex]

[tex]y = 550 - 11 * 47[/tex]

[tex]y = 550 - 517[/tex]

[tex]y = 33[/tex]

So:

[tex](x,y) = (47,33)[/tex]

(3)

[tex]x - y = 19[/tex]  and [tex]-12x + y = 168[/tex]

Make y the subject in [tex]-12x + y = 168[/tex]

[tex]y = 168 + 12x[/tex]

Substitute [tex]y = 168 + 12x[/tex] in [tex]x - y = 19[/tex]

[tex]x - 168 - 12x = 19[/tex]

Collect like terms

[tex]x -12x = 168 + 19[/tex]

[tex]-11x = 187[/tex]

Solve for x

[tex]x = -17[/tex]

Solve for y in [tex]y = 168 + 12x[/tex]

[tex]y =168-12 *17[/tex]

[tex]y =-36[/tex]

So:

[tex](x,y) = (-17,-36)[/tex]

Answer:

There are 24 girls in the class.

Step-by-step explanation:

Write out the problem like this:

40 = (g-8)+(g)

40 is the total amount of students. (g) is the unknown number of girls in the class, and (g-8) is the amount of boys since there are 8 fewer boys than girls.

First, eliminate the parentheses.

40 = g - 8 + g

Next, combine like terms. Both g's are positive, to we get 2g

40 = g - 8 + g

40 = 2g - 8

Then, add 8 to both sides of the equation, because the 8 that was already present is negative and needs to be canceled out.

40 + 8 = 2g - 8 + 8

48 = 2g

Lastly, divide both sides by 2, so that the (g) is by itself.

40/2 = 24, 2g/2 = g

g=24

This can be tested as the correct answer by subtracting 8 from 24 to count the boys...

24 - 8 = 16

...and adding the two amounts together to get the total amount of students.

24 + 16 = 40

There are 24 girls in the class.

Answer:

7.5 bag

Step-by-step explanation:

Carton #1: 19 berries

Carton #2: 26 berries

^^add them up together to get hte total amount of berries! 19 + 26 = 45

She has 45 berries in total, then you divid it by 6 aka the amount of berries she wants in each bag 45 ÷ 6 = 7.5

When she divids them up she has 7 bags with 6 berries in each and 1 bag with 3 berries.

Try it.

Answer: 1st: No, 2nd: No, 3rd: Yes, 4th: Yes

Step-by-step explanation: You only flip the inequality when you divide a negative number on both sides. The only reason why you would divide would be to get the variable by itself -  in this case the coefficient would need to be negative. That only applies to the third and 4th equations.

Answer:

Quinn's Taxi Service

Step-by-step explanation:

a) Yesterday, 37% of the drivers for Quinn's Taxi Service worked.

Hence, the percentage for Quinn's Taxi Service drivers that are working is 37%

b) At Bella's Taxi Express, 3 out of 10 drivers worked.

The percentage for Bella's Taxi drivers that are working is calculated as:

3/10 × 100

= 30%

Therefore, the taxi service that had a greater percentage of its drivers working is Quinn's Taxi Service with a high percentage of 37%
