Answer:
3 degrees F
Step-by-step explanation:
-4 + 7 = 3
The temperature at 5:00pm was -4°F. The temperature rose (it means adding) 7°F once the sun came up at 8:00am.
Write an addition expression.
(-4)+(+7)
-4+7
+3
(The answer is positive because it matches the sign of 7, the numerically larger number)
Therefore, the temperature was 3°F.
Calculate Mechanical Advantage To lift a crate, a pulley system exerts a force of 2,750 N. Find the mechanical advantage of the pulley system if the input force is 250 N
Answer:
2750/250= 11. Therefore, your mechanical advantage would be 11.

What is the difference between a photon and a molecule?
Answer:
See Explanation
Step-by-step explanation:
An atom is the smallest particle of matter holding the basic properties and characterstic of the matter. An atom consist of positive charged protons and chargeless neutrons at its centre and the negatively charged electrons are revolving around the nucleus. An atom do consist of energy levels corresponding to which the electrons revolve around the nuclues in the respective energy level.
Now a photon is an energy packet, or we can say a particle of light carring energy with it.
An atom is a particle of a matter and a photon is a particle of light.

paul is going to a college where tuition for one year is $14,200. He has a scholarship worth $1,500 and a grant worth $200. He earns $125 a week at this job how many weeks does paul need to work to pay 50% of the remaining tuition.
hurry pl ill make brainliest
Answer: 50 weeks
First, since he has a scholarship and a grant, those are used to pay off college debt. So $1,500 + $200 = $1,700
Now we subtract that from the total debt.
$14,200 - $1,700 = $12,500
Now since we're only seeing how much can pay for HALF of his debt, we divide $12,500 by 2.
$12,500 ÷ 2 = $6,250
Finally, we have to divide by the amount of money he earns in a week to find the total weeks.
$6,250 ÷ $125 = 50
50 weeks!
Hey, read the image...
I, flameflam, have read the image ;)
The sum of the residuals should always be 0 because the predicted values should be that close to the actual values.
True or false
Answer: True
Step-by-step explanation:
The sum of the residuals is always 0 so the plot will always be centered around the x-axis. An outlier is a value that is well separated from the rest of the data set. An outlier will have a large absolute residual value.
z divided by 6 + 15 = 24
Answer:
z/6+15=24
We move all terms to the left:
z/6+15-(24)=0
We add all the numbers together, and all the variables
z/6-9=0
We multiply all the terms by the denominator
z-9*6=0
We add all the numbers together, and all the variables
z-54=0
We move all terms containing z to the left, all other terms to the right
z=54
Step-by-step explanation: hope it helps
Answer:
z = 54
Step-by-step explanation:
[tex]\frac{z}{6}+15=24[/tex]
[tex]6(\frac{z}{6})+15=24[/tex]
z + 15 = 24
z + 15 - 15 = 24 - 15
z = 54
-5 = 1/3(-1-w)
pls help! i will give brainly
Answer:
w=14
Step-by-step explanation:
Let's solve your equation step-by-step.
−5= 1/ 3 (−1−w)
Step 1: Simplify both sides of the equation.
−5= 1/ 3 (−1−w) −5=( 1/ 3 )(−1)+( 1/ 3 )(−w) (Distribute)
−5= −1/ 3 + −1/ 3 w
−5= −1/ 3 w+ −1/ 3
Step 2: Flip the equation.
−1/ 3 w+ −1/ 3 =−5
Step 3: Add 1/3 to both sides.
−1/ 3 w+ −1/ 3 +1/ 3 =−5+ 1/ 3
−1/ 3 w= −14/ 3
Step 4: Multiply both sides by 3/(-1).
( 3 −1 )*( −1/ 3 w)=( 3/ −1 )*( −14/ 3 )
w=14
Answer:
w=14

576
Step-by-step explanation:
36 times 16 is 576
that probably didn't answer the question tho
Answer:
a = 3
b and c = 144
Step-by-step explanation:
since vertical angles congruent
12a = 36
a = 3
A line is 180 degrees so 12a = 36
180-36 = b and c
since vertical angles are congruent
b and c = 144

Answer:
62
Step-by-step explanation:
Answer:
The median is 62 beause it falls between the 60 and is no where near 20 or 30 70 is higher on your can find the median by looking at the lines the two ones or if the numbers are line up it would be the one one in the middle if there are two number is the middle in would be between those to numbers example 28 and 29 it would 28.5 hope this helpsStep-by-step explanation:
