Raul is performing an experiment. He pours water into a glass and measures the temperature of the water at 72.3°F. Then he adds a few ice cubes to the glass of water. He measures the temperature of the water again and finds that it has changed by -39.1°F.
Simplify the expression in (-30) + 70 + (-9) + 2 +(-0.1) + 0.3 = 2 + (-9) + 70 + (-0.1) + 0.3 + 70
Answer:
When you add the left side of the equation, you get 33.2 because 70-30 is 40, 40+2 is 42, 42-9 is 33, 33+0.3 is 33.03, 33.3-0.1 is 33.2.
Step-by-step explanation:
Answer:
[70 + (-30)] + [2 +(-9)] + [0.3 + (-0.1)]
=
40 + (-7) + 0.2
=
33 + 0.2
=
33.2°F
The temperature of the water dropped to 33.2°F after Raul added the ice cubes.

Which panda will weigh more at 5 weeks?
Write the equation for each panda.
Answer:
they will weigh the same they will both weigh 25 pounds
mochi is 5 pounds at one week and so is the other panda so at 5 weeks they will both be 25 pounds
What does the point (0, 35) represent?
Answer:
the students read 35 pages in class to start the book
Step-by-step explanation:
that would only make sence, because 35 starts at 0, not 1, so your starting at 35, in class

The arrows should point in the negative direction.
The small arrows should end in the same place as the large one.
The arrows should end on negative 15.
The arrows should start at zero.
There should be 5 small arrows.
Answer:. The arrows should point in the negative direction.
The arrows should end on negative 15.

Isabelle takes the bus to work. The bus ride to work costs her $2.50 each time. She could buy a bus pass for a one-time fee of $15.00 and would then only pay $1.00 each time to ride the bus. How many times would she have to take the bus for the cost to be the same?
y = total cost
x = amount of times she takes the bus
Let's create two equations to model the data in the problem above.
y = $2.50x
y = $1x + $15
Now, let's set them equal to each other and solve for x.
$2.50x = $1x + $15
Subtract $1x from both sides.
$1.50x = $15
Divide both sides by $1.50
x = 10
She would have to ride the bus 10 times for the cost to be equal.
Answer:
10 Trips
Step-by-step explanation:
Create 2 algebraic Equations, X is the number of trips and y is the total cost. y=2.5x, and y=x+15. Set them equal to eachother and solve for X. 2.5X=X+15. Subtract X from both sides to get 1.5X=15. Divide by 1.5 to get 10. X=10, 10 Trips!

A pair of parallel lines is cut by a transversal. What are the measures of the two marked angles?
CHOICES
40 degrees and 40 degrees
40 degrees and 140 degrees
65 degrees and 115 degrees
75 degrees and 105 degrees
Answer:
Let us mark the points R and S on line p, T and U on line q, A and B on line l and C and D on line m.
Suppose the lines p and q intersect the line l at K and L respectively and line m at N and M respectively.
Since, AB is a straight line and ray KN stands on it, then
∠NKL + ∠NKA = 180∘ (Angles in a linear pair)
⇒110∘ + a = 180∘
⇒a = 180∘ − 110∘ = 70∘
Since, line p || line q and line l is a transversal intersecting them at K and L, then
∠TLB = ∠NKA (Alternate exterior angles)
⇒b = a
⇒b = 70∘
Since, line p || line q and line m is a transversal intersecting them at N and M, then
∠CNK = ∠NML (Corresponding angles)
⇒c = 115∘
Since, CD is a straight line and ray ML stands on it, then
∠NML + ∠LMD = 180∘ (Angles in a linear pair)
⇒115∘ + d = 180∘
⇒d = 180∘ − 115∘ = 65∘
Amira needs 24 and StartFraction 3 over 10 EndFraction feet of fencing material to make a fence for her small garden. Which number represents the additive inverse of this number?
Negative 24 and StartFraction 3 over 10 EndFraction
Negative 24
StartFraction 3 over 10 EndFraction
24 and StartFraction 3 over 10 EndFraction
Answer:-24 3/10
Step-by-step explanation:We have been given that Amira needs feet of fencing material to make a fence for her small garden. We are asked to find the additive inverse of our given number.
We know that additive inverse of a number is that number, which we add to a number to create the sum of zero.
george's continer was partially full. then he added 177 millters more liquid to the container. now the container has a total of 266 millitera of liquid was in the container before george added more? answers A) 79 mL B) 89 mL C) 111 mL D) 443 mL Whoever answers first gets a giftcard i buy it private message you and give you the code i have to buy it the picture shows the container
Answer:
B) 89mL
Step-by-step eplanation:
Answer:
I believe the answer is 89
Step-by-step explanation:
If he now has 266 millitera of liquid in the container that means he first had 89. You take 89 and add the 177 that you added to the container and you get your total of 266.
