Answer 1

Answer:

1.) Triangle ABC is congruent to triangle DCB

Step-by-step explanation:

For the first one, the first 3 steps proved that all 3 sides in the 2 triangles formed by the diagonal are congruent to each other, meaning triangle ABC is congruent to triangle DCB (I named it like that specifically because the way you name the triangles has to be the exact same way you named the other triangle).

For the second one, the congruency statement should be GL ≅ AD, because the HL congruence theorem states that if a hypotenuse and leg of one right triangle is congruent to the hypotenuse and leg of another right triangle, those triangles are congruent.

Answer 2

Answer:

choice 4) Triangle ABC is congruent to triangle DCB because of the Side-Side-Side theorem

Elise had a credit card balance of -$120. She
made a payment of $70 this month. Write and
then evaluate a SUBTRACTION expression to
find her new credit card balance.

Answers

Answer:

15.50+n=325.00

Step-by-step explanation:

15.50+what she had in the bank already = what she has now

Step-by-step explanation:

Elise's new credit card balance is $-50.

Elise's credit card balance is negative. This means that she has withdrawn more money than she has deposited. Elsie thus owes the bank $-120. If she paid $70, the amount she owes would be reduced by $70.

Elise's new credit card balance = credit card balance + payment made

$-120 + $70 = $-50

The cylinder and the sphere below have the same radius and the same volume. What is the
height of the cylinder?

A.8m
B.6 m
C.4m
D.9m

Answers

The answer would be 8 or A

Step by Step Explanation:

First you have to find the volume of the Sphere.

Set the problem up like this: V = Volume
V= 4/3 • pi (3.14) • 6(3)
= 904.32

Now you have to volume and as stated the volume and radius is the same for both the cylinder and sphere. So now you plug in the answers for the letters.
Formula for (V) Volume of Cylinder is:
V= Pi (3.14) • R (radius) (2) • H (height)
So plug in for what you know
904.32 = 3.14 • 6(2) • H
904.32 = 3.14 • 36 • H
113.04/904.32 = 113.04 • H/113.04
8 = H

The answer is A

Im dying bro help The vertices of a quadrilateral are (2, 3), (3, 8), (7, 5), and (6, 2). Draw the quadrilateral in the coordinate plane.

Answers

Okay to the first number in the ordered pair is the x and the second is the y. So (x,y) when you put a dot on the coordinate plane such as (2,3), you have to go the the horizontal line which is x and go over right 2 spaces(depending on how many numbers is one space) then go up 3. Do that same thing for each of the order pairs. Eventually you will have 4 dots. Connect those dots then you will have the quadrilateral. I hope this helps you!

Answers

Answer:

because 3 spheres is inside the cylinder and they are placed close together

=> The height of the cylinder is 3 times the diameter

=> the height is 18cm

the volume of the cylinder is 3,14.18.(6/2)² = 508,68

because 3 spheres have the same diameter

=> the volume of 3 spheres is 4.3,14.3³ = 339,12

=> the volume of the cylinder that is left empty is 508,68 - 339,12 = 169,56

Step-by-step explanation:

Answer:

The answer is 508,68

Step-by-step explanation:

Since the volume of the cylinder is equal to the area of the permanent base multiplied in the height

Since the radius of the base is equal to 3 and since the area of its cylinder is equal to

[tex]314 \times 3 \times 3 = 28.26[/tex]

When the height equal to 18

Then the volume equal to

[tex]28.26 \times 18 = 508.68[/tex]

Brad has $75 in his savings account and adds $25 every month he doesn't make any withdrawals from the account which inequality shows the number of months it would take Brad to save at least $200

Answers

It would take Brad five months with adding $25 every month with a starting value of $75 in his bank account to save at least $200

The inequality representing the problem will be x+3 ≥ 8

What is inequality?

A relationship between two expressions or values that are not equal to each other is called inequality.

Given that, Brad has $75 in his savings account and adds $25 every month he doesn't make any withdrawals from the account, and saves at least $200.

Let the number of months be x,

75 + 25x ≥ 200

25(3+x) ≥ 200

x+3 ≥ 8

Hence, The inequality is x+3 ≥ 8

Answer:

m=-6

Step-by-step explanation:

-m + 8 = -4m -10

+m. +m.

8= -3m -10

+10. +10

18 = -3m

/-3m /-3m

-6=m

Answer:

m=-6

Step-by-step explanation:

–m + 8 = –4m − 10

Subtract 8 from both sides

-m+8-8=-4m-10-8

Simplify:

-m=-4m-18

Add 4m to both sides

-m+4m=-4m-18+4m

Simplify:

3m=-18

Divide both sides by 3

3m/3=-18/3

-18/3=-6

m=-6

How did labor unions and African Americans intersect during the era? What role did black people play in strikes? Points to consider:Although the Knights of Labor allowed black membership, by the 1890s the organization had lost influence to the American Federation of Labor. Founded in 1886, the AFL was ostensibly open to all skilled workers, but most of its local craft unions barred women and black tradesmen. In contrast, the United Mine Workers (UMW), formed in 1890, encouraged black coal miners to join the union rather than serve as strikebreakers. By 1900 approximately 20,000 of the 91,000 members of the UMW were black men. The Industrial Workers of the World, a revolutionary labor organization founded in 1905, brought black laborers and white laborers together. In 1869 a Baltimore ship caulker, Isaac Myers, organized the National Colored Labor Union, which lasted for seven years. Black stevedores periodically went on strike in Charleston, Savannah, and New Orleans. The Longshoremens Protective Union in Charleston won several strikes in the 1870s. In Nashville in 1871 black dockyard workers went on strike, demanding 20 cents an hour.2. What was the educational debate between Booker T. Washington and W. E. B. Du Bois?
