Answer:
95%
Step-by-step explanation:
So, we can see on the chart that 78 out of 82 people from ages 18 to 22 use Face.book. So we're trying to find what percentage 78 is of 82:
The first step is to write 78 as a fraction of 82, which is:
78/82
In order to find the simplest form of 78/82 we cancel out the greatest common divisor of 78 and 82, which is 2 :
78/82 = 37/41
Now we just need to convert this fraction to a percentage :
37/41 = 95% (rounded)
So we have the final answer :
78 is 95% of 82
Which means that:
Approximately 95% of people from ages 18 to 22 use Face.book
hope this helps:)

Step-by-step explanation:
Now we have to,
→ Find the equivalent expression.
The property we use,
→ Distributive property.
The expression is,
→ 8(a + 4)
Let's simplify the expression,
→ 8(a + 4)
→ 8(a) + 8(4)
→ (8 × a) + (8 × 4)
→ 8a + 32
Hence, the answer is 8a + 32.

PLS ANSWER
Answer:
I believe that the answer is 21x+14 and 7(3x+2).
Step-by-step explanation:
I hope this helps, have a blessed day.
Answer:
A. 21x + 14 and 7(3x + 2).
Step-by-step explanation:
23x - 14 + 2x = 21x + 14
25x - 14 ≠ 21x + 14
x + x + 5 = x² + 5
2x + 5 ≠ x² + 5
9x² + 9x + 5 ≠ 18x² + 5
21x + 14 = 7(3x + 2)
21x + 14 = 21x + 14.
Your answer is A, 21x + 14 and 7(3x + 2).
cone A and cone B are similar. The radius of cone a is 5.4 feet and the radius of cone b is 16.2 feet. if the surface area of cone a is 43 square feet, find the surface of cone b
The surface area of cone B is 387 square feet.
What is a cone?It is a shape of a christmas tree where there is a base of radius r and a top point called the apex.
We have,
Since the cones are similar, their corresponding dimensions are proportional.
In particular, the ratio of their radii is equal to the ratio of their surface areas.
Now,
Let S be the surface area of cone B, then we have:
ratio of radii = 16.2/5.4 = 3
ratio of surface areas = S/43
Since the ratio of surface areas is equal to the ratio of radii squared,
We have:
3² = S/43
9 = S/43
S = 9 x 43
S = 387
Therefore,
The surface area of cone B is 387 square feet.

Answer:d
Step-by-step explanation:
Answer:
D) 472
Step-by-step explanation:
Surface Area formula:
SA = 2(wl + hl + hw)
Given:
w = 7
l = 12
h = 8
Work:
SA = 2(wl + hl + hw)
SA = 2(7 x 12 + 8 x 12 + 8 x 7)
SA = 2(84 + 96 + 56)
SA = 2(236)
SA = 472

Many games involve chance and they usually involved either dice or cards. For this activity, we will look at a common game called 7‐11 where two dice are rolled. If the roll adds up to 7 or 11, the player wins. If the roll adds up to 2, 3, or 12, the player loses. If there is any other sum, it is a draw (no winner or loser). Use this two‐dice roll scenario to complete the problems below.
1. Create a tree diagram to determine all the possible outcomes of rolling two dice.
