A = (-1, 7) and B = (-5, 2)

Answers

Answer 1

Answer:

[tex]midpoint = \frac{-1 + -5}{2} , \frac{7+ 2}{2}[/tex]

(-3,[tex]\frac{9}{2\\}[/tex]) is the center of the circle

Step-by-step explanation:

You use the midpoint of the two point given to us.

Hope this helped

find surface area of the square pyramid!!! pls i need help with explaining!!!!!

Answers

Answer:

39 square yards

Step-by-step explanation:

The base is a square, so the area is 3 x 3 = 9.

Each side is a triangle, and the formula for that is (1/2)(base)(height)

The base of each side is 3 and the height of each is 5. There are 4 of those, so it's 4 x (1/2)(3)(5) = (2)(3)(5) = 30

Add the base and sides

30 + 9 = 39

Answer:

39 yards

Step-by-step explanation:

surface area = A + [tex]\frac{1}{2}[/tex] ps

A = area of the base

p = perimeter of the base

s = slant height

the base of the pyramid is a square, all sides and angles are equal

; 3 yards

; area of a square = l x w

; area of the base = 9 yd (A)

perimeter of the base ; 3 + 3 + 3 + 3 = 12 yd (p)

slant height = 5 yd (s)

; sub it into the formula

surface area = 9 + [tex]\frac{1}{2}[/tex] x 12 x 5

surface area = 39 yd

Answer:

4.5 cm

Step-by-step explanation:

The volume of a sphere is given by

V = 4/3 pi r^3

121.5 pi = 4/3 pi r^3

Divide each side by pi

121.5 = 4/3 r^3

Multiply each side by 3/4

3/4 *121.5 = 3/4 * 4/3 r^3

91.125 = r^3

Take the cube root of each side

(91.125)^ (1/3) = r^3 ^(1/3)

4.5 = r

Which of the following situations combine to make zero?

A- A friend opens a checking account with $30. His first purchase made with his debit card totals $28

B- The temperature falls 10 degrees below zero and then rises 20 degrees to be 10º F

C- A friend borrows $20 and promises to return double the amount.

D- A start up business has income equal to its expenses.

Answers

Answer:

Step-by-step explanation:

Why A is wrong:

If a friend has $30 in his checking account and he made a purchase of $28, the equation would be:

30-28 = $2, which does not equal zero.

Why B is wrong:

The temperature was zero and went down to negative ten. It went up to 10, not zero. So this is also wrong.

Why C is wrong:

A friend borrowed $20 dollars and promised to return double the amount, $40. The equation for this is:

20 - 40 = -20, which also does not equal zero

Why D is correct:

Income is how much you earn

Expenses is how much you pay.

If both of them are equal, then your income is zero, which is the correct answer.

Hope this helps :)

which angles are complementary to each other ? select all that apply

Answers

Answer: ∠1 and ∠5

Step-by-step explanation:

You can see that all of the other angles are exactly 90 degrees. The remaining two are angles 1 and 5 which means that they have to be 90 degrees. Since they are together, they also look perfectly like a 90 degree angle.

Hope this helps :)

Angle 1 and Angle 5 are complementary because the sum of both of those angles equals 90 degrees and the other 3 angles cannot be complementary to each other because they are already 90 degree angles by themself

1.45 degrees

2.45 dehrees

3.135 degrees

4.135 degrees

5.45 degrees

6.135 deegres

please give brainliest

Answer:

Step-by-step explanation:

for first fox

let it be x

x + 135 degree = 180 degree (being straight line)

x = 180 - 135

x = 45 degree

therefore figure upper box is 45 degree

for box that is just below 135 degree

first fox = box just just below 135 degree

45 degree = box just below 135 degree

for box that is just below 45 degree

box that is just below 45 degree = 135 degreee (being vertically opposite angles)

for the box that lies on the left side of the transversal

let the fourth box that les on the left side be x

135 + x = 180 degree (being co interior angle)

x = 180 - 135

x = 45 degree

for the box that lies on the right side of the transversal .Let it be y

45 + y = 180 degree

y = 180 - 45

x = 135 degree

y = last box that lies on the left side of 45 degreeing vetically opposite angles)y

last box = 135 degree

Solve the following equation.
U + 2 = 4

Answers

Answer:

U=2

Step-by-step explanation:

This is a simple one-step algebraic equation. In algebra to solve equations, you should use the properties of equality. The properties say that an equation remains true as long as the same thing happens on both sides. For this equation, the property of subtracting should be used; this property states that the same number can be subtracted from both sides. To find U, isolate the variable by subtracting 2 from both sides. This leaves U=2.

U +2= 4
-2 -2
U = 2
2 + 2= 4
