Calculate the height of a right circular cylinder with a surface area of 300 square inches and a radius of 5 inches. a. 2.45 inches c. 8.25 inches b. 4.55 inches d. 3.65 inches

Answers

Answer:

The height of the right circular cylinder is 4.55 inches ⇒ b

Step-by-step explanation:

The formula of the surface area of a right circular cylinder is

S.A = 2πrh + 2πr², where

r is its radiush is its height

∵ The surface area of a right circular cylinder is 300 square inches

S.A = 300 in.²

∵ Its radius is 5 inches

r = 5 in.

∵ π = 3.14

→ Substitute them in the rule above

300 = 2(3.14)(5)(h) + 2(3.14)(5)²

∴ 300 = 31.4h + 157

→ Subtract 157 from both sides

∵ 300 - 157 = 31.4h + 157 - 157

∴ 143 = 31.4h

→ Divide both sides by 31.4

∵ 4.554140127 = h

4.55 = h

The height of the right circular cylinder is 4.55 inches

The equation x+3y=2 can be rewritten in the equivalent form y=___x+____ which revels a slope equals to ___


-3,-2,-1,-2/3,-1/3,1/3,2/3,1,2,3

Answers

Hello!

[tex]\large\boxed{Slope = -\frac{1}{3}}[/tex]

x + 3y = 2

Rewritten into slope form: y = mx + b

Find the slope when rewritten:

Move x to the right hand side of the equation. (Subtract)

x - x + 3y = 2 - x

3y = 2 - x

Divide both sides by 3:

y = 2/3 - 1/3x

Rearrange:

y = -1/3x + 2/3.

The slope is equivalent to -1/3.

Your job is to sort and sack marbles for sale a bag contains 55 marbles some red and some green if there are 11 red marbles what is the ratio of red to green marbles?

Answers

Answer:

1:4

Step-by-step explanation:

There are only two colours available, red and green.  We know that there are 11 red marbles and 55 marbles altogether, so the number of green marbles must be 55 - 11, or 44.  That means that the ratio of red to green marbles is 11:44, or 1:4.

x= 6, y=7

solve for the first variable in one of the equations, then substitute the result into the other equations.

The value of x is 0.05 and y is 4.8 for given system of equations.

What is Equation?

Two or more expressions with an Equal sign is called as Equation.

The given  system of equations are

y=2+56x...(1)

4x−3y=3...(2)

Substitute (1) in equation (2)

4x-3(2+56x)=3

4x-6+168x=3

172x-6=3

Add 6 on both sides

172x=9

Divide both sides by 172

x=9/172

x=0.05

Now plug in x value in equation 1

y=2+56(0.05)

=2+2.8

y=4.8

Hence, the value of x is 0.05 and y is 4.8 for given system of equations.

Ob babysits the kids next door every day after school for 1.5 hours. He earns $3.50 an hour. How much money will he earn in 6 weeks if school is in session 5 days a week the whole time? Show your work.

Answers

Answer:

$157.5

Step-by-step explanation:

Given that:

Number of hours worked after the school = 1.5 hours

Earnings per hour = $3.50

Earnings for one day or 1.5 hours = 1.5 \times 3.50 = $5.25

Earnings for 5 days or a week = Number of days [tex]\times[/tex] Earnings for 1.5 hours = 5 [tex]\times[/tex] 5.25 = $26.25

Number of weeks for which Ob works = 6

Total earnings in 6 weeks = Number of weeks [tex]\times[/tex] Earnings in one week = Number of weeks [tex]\times[/tex] Earnings in 5 days

Total earnings in 6 weeks = 6 [tex]\times[/tex] $26.25 = $157.5

C: 42x - 8y - 5.3
D: 84x - 16y - 5.3

Answers

Answer:the answer is a

Step-by-step explanation:

The expression 2(14x - 3y + 28x + 12.2 - 5y - 17.5) is equivalent to the expression 84x - 16y -10.6 option (A) is correct.

What is an expression?

It is defined as the combination of constants and variables with mathematical operators.

We have an expression:

= 2(14x - 3y + 28x + 12.2 - 5y - 17.5)

= 28x - 6y + 56x + 24.4 - 10y - 35

Adding like terms

= 84x - 16y -10.6

Thus, the expression 2(14x - 3y + 28x + 12.2 - 5y - 17.5) is equivalent to the expression 84x - 16y -10.6 option (A) is correct.

the sum of three angles of a triangle adds up to 180 degrees. In this problem, you are given two angles.

x+(2x+15)+the measure of angle Q should equal 180.

Since everything is addition, the parenthesis can be removed.

x+2x+15+Q=180. This can then be simplified to 2x+15+Q=180. Subtract 15 from both sides to get 2x+Q=165. Divide both sides by two to get the x by itself. x+Q=82.5.

Write the formula for the volume V of a cube with sides of length t. is V a function of t?

Answers

Answer:

The volume of a cube with the side length 't' will be:

V = t³

Yes! the volume of the cube is a function of the side length as the volume is a dependent quantity and depends on the value of side length.

Step-by-step explanation:

We have to determine the volume of a cube

We know that volume is the measurement of how much space a 3-d object takes up.

Given that the cube with the side length 't'.

As every edge of the cube is the same length.

Thus, the volume of a cube with the side length 't' will be:

V = t³

For example, if the side length t = 2 cm

Then,

V = 2³ = 8 cm³

Yes, the volume of the cube is a function of the side length as the volume is a dependent quantity and depends on the value of side length.
