Answer:
[tex]x = 27[/tex]
Step-by-step explanation:
Given
The attached figure
Required
Solve for x
3x and 45 are supplementary angles
So:
[tex]3x + 45 = 180[/tex]
[tex]3x =- 45 + 180[/tex]
[tex]3x =135[/tex]
Solve for x
[tex]x = 135/5[/tex]

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.

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

Raul is making chocolate chip pancakes. The number of chocolate chips he uses is proportional to how many ounces of mix he makes. The recipe said that for ever 2 1/2 ounces of mix, 12 chocolate chips be added. What equation represents the relationship between c the number of chocolate chips and m the number of ounces
Answers
Answer:
12 = 5k/2
24 = 5k
Step-by-step explanation:
Raul is making chocolate chip pancakes.
The number of chocolate chips he uses is proportional to how many ounces of mix he makes.
Hence,
Chocolate chips ∝ Number of Ounces
Chocolate chips = c
Number of Ounces = m
= cm
c = km
Where k = Constant of Proportionality
The recipe said that for every 2 1/2 ounces of the mix, 12 chocolate chips be added.
Hence
12 = 21/2 × k
12 = 5/2 × k
12 = 5k/2
Cross multiply
12 × 2 = 5k
24 = 5k
The equation that represents the relationship between c the number of chocolate chips and m the number of ounces is
12 = 5k/2
24 = 5k

Answer:
A) He used 2/3 yard of wire
B) He had 4/15 yard of wire left
Step-by-step explanation:
An electrician had 14/15 yard of wire
He used 5/7 of the wire
A) How many many parts of wire did the Electrician use?
This is calculated as:
5/7 of 14/15 yard of wire
= 5/7 × 14/15 yard
= 2/3 yard of wire
He used 2/3 yard of wire
B) How many yards of wire does the Electrician have left?
This is calculated as
14/15 yard - 2/3 yard
Lowest common denominator is 15
Hence:
14 - 10/15
= 4/15 yard of wire left
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

Please I really need help!
Answers
Answer:
1. $85
Step-by-step explanation:
multiply 17 by 5
The original price of the computer was $340 and in the second segment, the amount Peter borrows will be $5962.32.
What is the percentage?The percentage is defined as a given amount in every hundred. It is a fraction with 100 as the denominator percentage is represented by the one symbol %.
The percentage is also called the indicating hundredths. Thus, 9% is two-hundredth, which means 9%=9/100=0.09.
The percentage is just like the amount of that value but in between 1 to 100 and it is very useful to predict for example if you say 541 then we have to know about the full number also but if you say70% then it becomes clear.
The price of the computer let's say x than[( change in price)/(original price)] × 100 = 5%
[( $17 )/(original price)] × 100 = 5%
Original price = $340. hence, it will correct the answer
Principle amount $5000Rate of interest 9.2%
Time period 2 years
Interest after 1 year = $460
Principle amount after one year become $5000+$460 = $5460
Interest after 2 years will become = $502.32
Principle amount after the second year become
$5460 + $503.32 = $5962.32 will be correct answer.

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.
