Answer:

The surface area of a cylinder with the given dimensions is 571.48 [tex]cm^2[/tex].

Step-by-step explanation:

To find the surface area, you need to use the formula [tex]2\pi r^2 + h * 2\pi r[/tex] where [tex]r[/tex] represents the radius and [tex]h[/tex] represents the height. In this problem, the expression would be [tex]7^2 * 3.14 * 2 + 3.14*14*6[/tex] = [tex]49 * 6.28 + 3.14 * 84[/tex] = [tex]307.72+263.76[/tex] = 571.48 [tex]cm^2[/tex].

Answer:

145

Step-by-step explanation:

angles in a pentagon add up to equal 540

Hence, 110 + 90 + 80 + 115 + v = 540

( note that we just created an equation that we can use to solve for v )

We now solve for v using the equation created

110 + 90 + 80 + 115 + v = 540

step 1 combine like terms

110 + 90 + 80 + 115 = 395

we now have 395 + v = 540

step 2 subtract 395 from each side

540 - 395 = 145

395 - 395 cancels out

we're left with v = 145

Answer:

254/324 which is about 78.4%

Step-by-step explanation:

found area of entire square to be 18² or 324

found area of 4-quarter circles - which equals one circle with radius of 9

A = 81π which is about 70

subtracted 324 and 70 to get 254

ratio of shaded to unshaded is 254 : 324

The Probability of point to lie is in the shaded region= [tex]\frac{254.34}{324}[/tex]

Probability is simply how likely something is to happen. Whenever we're unsure about the outcome of an event, we can talk about the probabilities of certain outcomes—how likely they are.

Area of square=  side x side

                        = 18 x 18

                        = 324 sq. cm.

Area of 4 quadrant =4 x  [tex]\frac{\pi r^{2} }{4}[/tex]

                                = [tex]3.14 * 9 * 9}[/tex]

                                = 254.34 sq. cm.

So, probability that it is in the shaded region= [tex]\frac{254.34}{324}[/tex]

Answer:

Time taken to elapse the remaining $861  = 10.25 days

Step-by-step explanation:

Assuming that I am spending at a rate of -x dollars per day

Let initial amount be A

The rate of expenditure = 1281-861/5 = 84 dollars per day

Time taken to elapse the remaining $861 = $861/$84 per day

5u + 11 = 56

Step 2: Solve for u

Answer:

u = 9

Step-by-step explanation:

5u + 11 = 56

Subtract 11 from each side.

5u + 11 - 11 = 56 - 11

Simplify.

5u = 45

Divide each side by 5.

5u ÷ 5 = 45 ÷ 5

Simplify.

Hope this helps

Step-by-step explanation:

Remember math is a language

f(x) : A function of x where x can be any number including a number you choose

when you see f(-1), this tells you what the function is at this given x value. So you substitute - 1 wherever you see x

Answer:

the blue paints of 1.76 pints is used to paint her bedroom walls

Step-by-step explanation:

Given that

Tara uses 8.8 pints of white paint

And, the 4 by 5 of this amount represent the white paint

We need to find out the number of paint used by the blue paint

So,

= 8.8 - (8.8 × 4 ÷ 5)

= 8.8 - 7.04

= 1.76 pints

Hence, the blue paints of 1.76 pints is used to paint her bedroom walls

Add 1.50 to each time the price goes up

Step-by-step explanation: Multiply by two each time and you will have your answer 1 hot dog is 1.50 two are 3.00 use that method and you will have the correct answer

Answer: 5.5 inches, 3.5 inches

Step-by-step explanation:

Given

Barry wants to make a drawing i.e. half the size of original

The length and width of the original drawing are  11 inches and 7 inches respectively.

So, the intended drawing is obtained by multiplying the original dimensions by [tex]\frac{1}{2}[/tex]

The length of barry's drawing is

[tex]\Rightarrow 11\times \frac{1}{2}\\\\\Rightarrow 5.5\ \text{inches}[/tex]

The breadth of barry's drawing

[tex]\Rightarrow 7\times \frac{1}{2}\\\\\Rightarrow 3.5\ \text{inches}[/tex]

Answer: 20 boxes of chocolates

Step-by-step explanation:

First find out the total number of chocolates he has:

= 25 boxes * 24 chocolates per box

= 600 pieces of chocolate

The number of boxes needed if the chocolates are packed 30 in a box is:

= Total number of chocolates / Number of chocolates per box

= 600 / 30

= 20 boxes of chocolates
