I- GUESS WHO NEEDS HELP AGAIN...
I don't wanna fail math aaaa
Answer:
C
Step-by-step explanation:
Follow Pythagorean Theorem. a^2 + b^2 = c^2
We know b and c:
a^2 + 12^2 = 13^2
a^2 + 144 = 169
a^2 = 25
a = √25
a = 5
The answer is C because we know side a = 5

Can someone help me with my math work
Answer:
Step-by-step explanation:
So its difficult to show
Y= X-6 so what ever x is, y is six less than that so
X= -4 Y= -10
X= 0 Y=-4
X=4 Y=0
X=8 Y= 4
Then plot these on a graph like co-ordinates (x,y) and draw a straight line through them
Y= 4/3x -2 so whatever x is y is 4/3 and 2 less then that
X=-4 Y= -5
X=0 Y= -2
X=4 Y=1
X= 8 Y= 4
Then plot these on a graph like co-ordinates (x,y) and draw a straight line through them
Y= -2
Find minus 2 on the y axis and draw a horizontal line through it all the way across the grid.
Y= 2+ 1/4x so whatever x is y is 1/4 of x add 2
X=-8 Y= 0
X= -4 Y = 1
X=0 Y=2
X=4 Y=3
X=8 Y=4
Then plot these on a graph like co-ordinates (x,y) and draw a straight line through them
Do this method for 9
y = 2x -3 so whatever x is, y is 2 times that -3
y=2x +1 so whatever x is y is 2 times that +1
y= 2x so whatever x is y is 2 times that
Then plot the answers on a graph like co-ordinates (x,y) and draw a straight line through them
Make sure to label each line

Answer: 2^5
Step-by-step explanation: Diego should have added the exponents instead of multiplying them. I know it sounds weird but because both of the numbers are 2's you are able to combine them. When multiplying them together you should keep the base the same and add the exponents. In this case, 2^2 x 2^3 would be 2^5. Hope this helps.

Tomas is planning out a rail trail using a map with a marked grid. The head of the trail, which has an information kiosk, is located at (3, 0). He moves 1 unit east and 3 units north and places a pin at (4, 3) to represent the location of another information kiosk. He continues placing pins so that each pin is 1 unit east and 3 units north in relation to the previous pin. Which of the following points will have pins? Select all that apply.
A coordinate plane has an x-axis labeled East from 0 to 10 in increments of 1 and a y-axis labeled North from 0 to 10 in increments of 1.

Hypothetically. Relli’s in DeWitt had 30 workers in their restaurant in the year 2010. In 2011 they let go 20% of their workers due to budget cuts. In 2012, they are letting go another 10%. How many workers will they have at the beginning of 2013? Round to the nearest whole worker.
At the beginning of 2013, they would have 22 (21,6) workers.
30-20%(6)=24
24-10%(2,4)=21,6

cent
3 cents
20 cents
$5
Answer:
a. 40%
b. 8%
c. 135%
Step-by-step explanation:
4 dimes is 40 cents out of 100 cents, so that's 40%. 1 nickel is 5 cents and 3 pennies are 3 cents, which adds up to 8 cents out of 100 potential cents, so 8%. 5 quarters is 1.25 dollars and a dime is 10 cents, together it makes 1.35 dollars. Multiply that by 100 since there are 100 cents in a dollar and you get 135%

Solve the equation for x. Check the solution.
2. -5(x + 3) = 20
Answer:
x = -7
Step-by-step explanation:
-5( x + 3 ) = 20
Distributive property ( multiply whatever is in the parenthesis by -5)
-5 * x + -5 * 3 = 20
-5x - 15 = 20
Add 15 on both sides
-5x - 15 + 15 = 20 + 15
-5x = 35
Divide by -5 on both sides to isolate the variable
-5x/-5 = 35/-5
x = -7
Check...
Substitute the "x" with -7 since we already got that as our solution
-5( x + 3 ) = 20
-5( -7 + 3 ) = 20
Distributive property
-5 * -7 + -5 * 3 = 20
35 - 15 = 20
20 = 20 CORRECT
Hope this helped!

OH MY GOD PLZ HELP IM CLUELESS AND ITS DUE IN 30 MINS JSHDJDJCBDHJS
For question 1 the answer is b)
- Congruent angles have the same angle measure, and in a transversal, angles that are opposite around an intersection are congruent. For example ∠ 1 and ∠ 3 are congruent. Because the 2 lines are parallel (and intersected by the same line) the corresponding angles on the other intersection are also congruent. For example if ∠ 1 and ∠ 3 are congruent, then ∠ 5 and ∠ 7 are also congruent.
For question 2 the answer is b) 45°
- ∠ 3 and ∠ 4 are supplementary, meaning they equal 180° together. To solve you just need to subtract, 180° - 135° = 45°
For question 3 the answer is d) 145°
- This combines the previous 2 concepts. ∠ 1 and ∠ 5 are congruent (equal), ∠ 1 and ∠ 2 are supplementary. If ∠ 1 is 180° - 35° = 145°, and ∠ 1 and ∠ 5 are congruent, then ∠ 5 is also 145°.
For question 4 the answer is a) ∠ 1, ∠ 4, ∠ 5, and ∠ 8
- First, ∠ 4 is supplementary because it falls along the same straight line (line m), similarly ∠ 1 is supplementary because it falls along a different straight line (the transversal). Because lines n and m are parallel and both intersected by the transversal, the corresponding angles, ∠ 5 and ∠ 8, are also supplementary.
For question 5, the answer is b) m∠ 3 = 70°
- ∠ 7 is supplementary to the 110° angle, so m∠ 7 = 180°-110° = 70°, ∠ 7 and ∠ 3 are congruent, so m∠ 3 also equals 70°
Mark is making a scale model of his favorite truck. The actual truck is 12 feet long and 5 feet wide. He wants the model to be 30 inches in length. Using a proportion, find the model truck’s width.
Answer:
the model trucks width would be 12.5 inches.
Step-by-step explanation:
set up a proportion.
12/5=30/?
cross multiply.(this makes sense when the fraction is written out correctly)
5x30=150
now divide this by your remaining number in the fraction.
150/12=12.5

What is 35% of 80?
Please answer this within half an hour, Thanks!! :D
Answer:
28
Step-by-step explanation:
35÷100×80 which will give you 28 as the answer.
Answer:
the answer is 28
Step-by-step explanation:
to get this, you would change 35% to a decimal.
to do this you would move the decimal to the right 2 times ( 35.0-----> 0.35)
then, you would multiply 0.35 by 80, and you would get 28
