What is the value of n? Write your answer as a number only

### Answers

**Hey there!**

**The value of "n" is 10.**

Since the lines on the sides represent congruency of those 2 sides, we also know that angle T is equal to angle S. Since a triangle's angles add up to 180°, we can use the following equation, and solve:

**180 = 3.5n + 3.5n + 11n Add the "n"s**

**180 = 18n Divide both sides by 18**

**10 = n**

Fernando’s birthday is on March 21st. On March 9th, Fernando’s father said that he will give Fernando $5 on each date that is divisible by 4 until his birthday. On Fernando’s birthday, his father will give him $10 more than his new age. In all, Fernando will receive $40 from his father. How old will Fernando turn on his birthday?

### Answers

Answer:

15 years

Step-by-step explanation:

Days divisible by 4 between 9th and 21st (12, 16,20). = 3

Assume, New age = x

(3 * 5) + (10 + x) = 40

15 + 10 + x = 40

25 + x = 40

x = 40 - 25

x = 15 years

Hence, Fernando will be 15 years

Lin has a work of art that is 14 inches by 20 inches. She wants to frame it with large paper clips laid end to end.

1. if each paper clip is 1 3/4 inch long, how many paper clips would she need?

2. How many paper clips are needed if the paper clips are spaced 1/4 inch apart.

### Answers

Answer: See explanation

Step-by-step explanation:

First we have to calculate the perimeter of the work of art. This will be:

= 2(14 inches + 20 inches)

= 2 × 34 inches

= 68 inches

1. If each paper clip is 1 3/4 inch long, how many paper clips would she need?

This will be:

= 68 ÷ 1 3/4

= 68 ÷ 7/4

= 68 × 4/7

= 272/7

= 38 6/7

= 39 paper clip approximately.

2. How many paper clips are needed if the paper clips are spaced 1/4 inch?

This will be:

= 68 ÷ (1 3/4 + 1/4)

= 68 ÷ 2

= 34 paper clips

Write the expanded form of the expression. − 1/8(y+x)

### Answers

**Answer:**

(-1/8 * y) + (-1/8 * x)

**Answer:**

Solution:

the expanded form of the expression. − 1/8(y+x)

=-y/8 +-x/8

8x+6x=112+1x+7x=89

solve this

### Answers

First thing I would do is combine like terms to get 14x=112+8x=89

Then subtract 8x from 14x to get 6x=112=89

Then (I don't think this is right) subtract 112 from 89 to get -23 so it looks like this 6x=-23 then devide 6from both sides to get x=-23/6 or x=-3.83 3will be repeating

E-4 - 5 - 6 - → The perimeter of a rectangle is 425 yards. The length and width of the rectangle are each multiplied by 6. What is the perimeter of the new rectangle? yd.

### Answers

**Answer:**

** 2550yards**

**Step-by-step explanation:**

Perimeter of a rectangle = 2L + 2W

L is the length

W is the width

If perimeter of a rectangle is 425 yards, then;

425 = 2L + 2W

425 = 2(L+W)

L+W = 425/2 .... 1

If the length and width of the rectangle are each multiplied by 6

P = 6(2L) + 2(2W)

P = 12L + 12W

P = 12(L+W) .... 2

Substitute 1 into 2

P = 12(425/2)

P = 6*425

P = 2550yd

**Hence the perimeter of new triangle is 2550yards**

What is the surface area of a sphere with a circumference of 100T? Leave

your answer in terms of pie

### Answers

Answer:

10000π units²

Step-by-step explanation:

From the question given above, the following data were obtained:

Circumference (C) = 100π

Surface Area of sphere (SA) =?

Next, we shall determine the radius. This can be obtained as follow:

Circumference (C) = 100π

Radius (r) =?

C = 2πr

100π = 2πr

Divide both side by 2π

r = 100π / 2π

r = 50 units

Finally, we shall determine the surface area of the sphere. This can be obtained as follow:

Radius (r) = 50 units

Surface Area of sphere (SA) =?

SA = 4πr²

SA = 4 × π × 50²

SA = 4 × π × 2500

SA = 10000π units²

Therefore, the surface area of the sphere is 10000π units²
