Answer:
surface area: 62.5π
explanation:
total surface area of cylinder: 2πr(h+r)
Given:
radius = 2.5 inchheight = 10 inchSolve:
2π(2.5)(10+2.5)
5π(12.5)
62.5π
Solution:
Given:
Radius of cylinder: 2.5 inHeight of cylinder: 10 inSurface area of cylinder: 2πrh + 2πr²
Using the formula:
[tex]2\pi rh + 2\pi r^{2} = \text{Surface area of cylinder}[/tex]
[tex]\rightarrow 2(3.14)(2.5)(10) + 2(3.14)(2.5)^{2} = \text{Surface area of cylinder}[/tex]
Simplifying the LHS:
[tex]\rightarrow (3.14)(50) + 2(3.14)(6.25) = \text{Surface area of cylinder}[/tex]
[tex]\rightarrow (31.4)(5) + (6.28)(6.25) = \text{Surface area of cylinder}[/tex]
[tex]\rightarrow \boxed{\bold{196.25 \ in^{2} = \text{Surface area of cylinder}}}[/tex]
An experiment involves rolling a die and drawing a card from a standard deck of 52 cards.
What is the probability that the die lands on 4 and the card is a heart?
Answer:
1/24
Step-by-step explanation:
chance of rolling 4 - 1/6
Chance of pulling a heart - 13/52, or 1/4
To find P(roll a 4, and pull a heart) you must multiply the 2 answers to find your final answer. So, 1/4 x 1/6 = 1/24
Hope this helps, if this is wrong, i am sorry, i recently started this unit.

Write -9/22 as a decimal.
Answer:
-0.40909090909
Step-by-step explanation:
it is not not terminating or repeating so, it is not a rational number.
The solution shown for the equation is incorrect. What is the correct solution? What is the error?
(CHECK IMAGE BELOW FOR EQUATION)
What is the error?
A. The right side of the equation should be 6 after dividing each side by -4.
B. The right side of the equation should be 8 after subtracting -8 from each side.
C. The left side of the equation should be - r after dividing each side by -4.
D. The left side of the equation should be - 8+4r after distributing.
Answer:
The answer is D
Step-by-step explanation:
- x - equals positive so it would be -8+4r
Answer:
D
Step-by-step explanation:
Honestly I can't giv a detailed explanation, apologies. Negatives multiplied result in positives. Since -4 is negative and -r is also negative, expanded form should be +4r. Also the answer is r=6 in case you need it.

indirect measures and diagram?
Answer:
9. The man is 6 feet tall
10. Ms. Dydek's shadow would be 4 ft 6.3 inches
Step-by-step explanation:
Problem 9:
The 136 feet tall Ferris wheel casts a shadow of 34 feet so the shadow:object ratio is 34:136.
The man's shadow is 1.5 feet so this is what we're solving for:
1.5:x
34: 136
First, we need to find what 1.5 was multiplied by to get 34:
34/1.5 = 22 2/3 or 68/3
This means that 68/3x = 136:
68/3x = 136
x = 6
The man is 6 feet tall
Problem 10:
A 6 foot 4 inch or 76 inch tall person casts a shadow of 4 feet or 48 inches. This makes the shadow:object ratio 48:76.
We are trying to find the length of the shadow of a 7 foot 2 inch or 86 inch tall person:
48:76
x:86
First, determine what 76 was multiplied by to get 86:
86/76 = 43/38
This means that x = 48*(43/38).
x = 2064/38
x = 54 6/19 or 54.3in
Margo Dydek's shadow would be 54.3 inches or 4 feet and 6.3 inches long.
i need help with this
Answer:
Its the third one
Step-by-step explanation:
A perfect square is a number that is generated by multiplying two equal integers by each other. For example, the number 9 is a perfect square because it can be expressed as a product of two equal integers: 9 = 3 x 3.

d x 54 = 324,
What does d equal?
who ever answers first gets brainlest
Answer:
d = 6
Step-by-step explanation:
d × 54 = 324
Divide both sides by 54.
d × 54/54 = 324/54
d = 6
Answer:
D=6
Step-by-step explanation:
54 x 6=324
Here is how i know.
I times the tens 6 times so 50 x 6=300
50 x 1=50
50 x 2=100
50 x 3=150
50 x 4=200
50 x 5=250
50 x 6=300
Then I did ones(4)
4 x 1=4
4 x 2=8
4 x 3=12
4 x 4=16
4 x 5=20
4 x 6=24.
Then I added it 50 x 6=300 + 4 x6=24=324 so 54 x 6=324.
Hope it helps have a great day:)

Step-by-step explanation:
You want the simplified form of the rational expression difference ...

Common denominatorBoth terms can be expressed using the same denominator, then summed.
[tex]\dfrac{6}{x^2+4x-32}-\dfrac{x-5}{x-4}=\dfrac{6}{(x-4)(x+8)}-\dfrac{(x-5)(x+8)}{(x-4)(x+8)}\\\\\\=\dfrac{6-(x-5)(x+8)}{(x-4)(x+8)}=\dfrac{6-(x^2+3x-40)}{(x-4)(x+8)}=\boxed{\dfrac{-x^2-3x+46}{x^2+4x-32}}[/tex]

Additional comment
The process is fundamentally identical to finding the difference of numerical fractions. The least common denominator is found by considering factors of the denominators, just as it would be if they were pure numbers.

Match each table of information to its constant of proportionality.
Answer:
Table 1: 2
Table 2: 10
Step-by-step explanation:
Constant of proportionality - the ratio between two proportional quantities.
We see that the ratio between the two rows of numbers in the first table is 2 because (4 / 2 = 2), (6 / 3 = 2), (8 / 4 = 2) and so on and so forth.
We see that the ratio between the two rows of numbers in the second table is 10 because (20 / 2 = 10), (30 / 3 = 10), (40 / 4 = 10) and so on and so forth.
Answer:
Table 1 is 2, Table 2 is 10.
Step-by-step explanation:
Table 1: The constant of proportionality is 2 because 4/2 is 2, 6/3 is 2, etc.
Table 2: The constant of proportionality is 10 because 20/2 is 10, 30/3 is 10, etc.

A car can travel 476 miles on 14 gallons of gas. How far can the car travel on 20 gallons of gas?
Answer:
680 Miles
Step-by-step explanation:
You divide 14 into 476 so you can get the answer for one gallon of gas is however many miles. In this case 1g=34ml. Then you multiply 34 and 20 and you get 680 miles.
