Answers

Answer:

b=61

a=14

Step-by-step explanation:

The two lines are parallel, so

b= a+47

180- (47*2)=180-94= 86

33+86=119

b=180-119=61

a=b-47

a=61-47=14

x = 26°

Step-by-step explanation:

for these triangles to be congruent m∡B must equal m∡E

m∡B = 180 - (114+23) = 43°

to find 'x':  x + 17 = 43

                 x = 43 - 17 = 26

A rectangular fish tank is shown above. The base of the tank has an area of 58.4 feet2. What is the volume of water in the tank?

Answers

Answer:

525.6 ft^3 based on a Height of 9 ft

Step-by-step explanation:

Given data

Area of Base= 58.4 ft^2

The expression for the volume of a rectangular tank is given as

Volume= L*W*H

Volume= Area*Height

Although the question was not specific about the height, it is important that we have the height to get the volume

Say the height is 9 ft

Hence the volume is

V= 6*58.4*9

V= 525.6 ft^3

Can someone solve this ?plzz!!

Answers

Answer:

25/m^3

Step-by-step explanation:

(5m^2)^3 is just an expanded way of saying 125m^6. 125m^6/5m^9 is going to get you 25/m^3, as the 6 and the 9 cancel to get you 3 on the denominator, and 125/5 gets you 25.

Step-by-step explanation:

The slope of a line can be found with any two points from the line. Formally, slope, m, is defined as

m=(y2-y1)/(x2-x1), I’ll use points (1,4) and (4,-4) so

m=(-4-4)/(4-1)

What do you do if a variable does not cancel out?

Answers

It always cancels out lol
In general, if you have an equation in which all your variables cancel out, then it tells you that your equation is either true or false, independently of the vaues your variables take. In your example, you arrive at the equation 0=1, which is false. No matter what values you take for x and y, it will never be true.

What is the measure of each angle in a pentagon if the lengths of all five sides are equal?
A. 180
B. 120
C. 108
D. 60

Answers

Answer:

C (108)

Step-by-step explanation:

Angles in a pentagon must add up to 540 degrees.

All sides equal mean all angles are equal

so all you must do is divide 540 by 5, which gets you to 108.

You can use inverse operations to check the work

108 x 5 = 540

Find the missing length indicated?

Answers

Answer:

D. 15

Step-by-step explanation:

Let the missing length be represented as x.

Thus:

(24 - x)/12 = x/20 => angle bisector theorem

Cross multiply

20(24 - x) = x(12)

480 - 20x = 12x

480 - 20x + 20x = 12x + 20x

480 = 32x

480/32 = 32x/32

15 = x

Missing length = x = 15

ill mark brainlist plss help

Answers

We will want to solve for x
We will start by multiply both sides by 24 so we can cancel out the 24 on the left and get x by itself
Now we have
x = (9/72)*24
we can first multiply 24 by 9 to get 216
Now we have
x = 216/72
216 divided by 72 will get us 3
x = 3

1) Alexa won 80 super bouncy balls playing horseshoes at her school's game night. Later, she gave two to each of her friends.
She only has 8 remaining. How many friends does she have? 2) Jane spent half of her weekly allowance playing mini-golf. To earn more money her parents let her wash the car for $20. What is
her weekly allowance if she ended with $32? 3) 229 students went on a field trip. Six buses were filled and 5 students traveled in cars. How many students were in each bus?

Answers

Answer:1 is 36 friends. 2 is $24 as her weekly allowance. 3 is 37 students on each bus

Step-by-step explanation:1. 80-8 because 8 is the amount she has left. You would get 76 which is the amount she gave away. Then you divide 76 by 2 because she gave 2 balls to 1 friend. Then you get the amount of friends she has.

2. When we read the problem it says she spent half of her allowance on mini golf. The half is very important. She earns $20 from cleaning her parent’s car and ends up with $32 all you do is subtract the $20 from $32 because it’ll leave you with 1/2 the money she began with (32-20=12). Then she she already spent half of the money you can either add 12 or multiply the 12 by 2 to get your answer (12+12=24 or 12•2=24).

3.(229-5) you’re subtracting 5 from the 229 students because 5 of them traveled in car. Then you do 224 students divided by 6 buses and you should get 37 students per bus.
