3. PLEASE HELP! Jenna just opened a checking account at the bank. Within the first month, she deposited three checks for $34.98, $51.02, and $51.22. She withdrew $5.23 for new pencils, $5.22 for cards, and $7.89 for movies from her account in the same month.
(a) Write Jenna's withdrawals as negative rational numbers and her deposits as positive rational numbers.
(b) Order the rational numbers from least to greatest and explain your reasoning.
(c) What is the greatest deposit within Jenna's account so far?
Answers
Answer:C) She would have $216.88.
Step-by-step explanation:
A) Deposits: +34.98; +51.02; +51.22
Withdrawals: -5.23; -5.22; -7.89
B) -7.89, -5.23, -5.22, +34.98, +51.02, +51.22
The smallest amount will be the largest withdrawal, as it takes away from the account; the largest amount will be the largest deposit, as it adds to the account.
98 + 34.98 = 132.98 + 51.02 = 184.00 + 51.22 = 235.22 - 7.89 = 227.33 - 5.23 = 222.10 - 5.22 = 216.88
Select all expressions that are equivalent to 5% of 200.

Answers
D.10
To figure out what 5% of 200 is, you would multiply 200 by .05.
To figure out if 1/20 of 200 is 10, simply divide 200 by 20.

Answers
Answer:
Area: [tex]9 cm^{2}[/tex]
Step-by-step explanation:
Since all sides of a square have equal lengths, the area of the square is [tex]a^{2}[/tex] (a = length of a side).
Since the length of the side of the square is given (is 3cm), the area of the square is [tex](3cm)^{2}[/tex] = [tex]9cm^{2}[/tex]

The measures of the angles of a triangle are shown in the figure below. Find the

112°
Answer:
Submit Answer
Answers
4x +(18+x)+112=5x+19.9548
0.333333(5x+19.9548)
9514 1404 393
Answer:
28°
Step-by-step explanation:
The sum of angles in a triangle is 180°, so we have ...
(4x) +(x +18) +112 = 180
5x = 50 . . . . . . . subtract 130
x = 10
Then the two acute angles are ...
(4x)° = (4·10)° = 40°
(x+18)° = (10+18)° = 28°
The measure of the smallest angle is 28°.

A plane flies at a steady rate of 40 mph while a second plane flies at a steady rate of 100 mph. The planes are 200 miles apart and fly directly toward each other. In how many hours will they meet?
Answers
Answer:
1.43 hours
Step-by-step explanation:
Given that:
Speed of plane A = 40 mph
Speed of plane B = 100 mph
Distance between plane A and B = 200 m
In how many hours will they meet?
Recall :
Distance = speed * time
Let the time traveled by each plane = t
Since the total distance apart = 200m
Hence,
Plane A distance + Plane B distance = total distance
40t + 100t = 200
140t = 200
Divide both sides by 140
140t / 140 = 200 / 140
t = 1.4285 hours
t = 10/7 hours or 1.43 hours

The scale factor of a room for a scale drawing is 2.3. The actual length of a wall in the room is 46 feet and the actual width of the room is 69 feet. What is the area of the scale drawing?
Answers
600 square feet.
Step-by-step explanation:
The actual length of a wall in the room is 46 feet and the actual width of the room is 69 feet.
It is given that:
The scale factor of a room for a scale drawing is 2.3.
The length of the room according to the scale drawing will be:
46÷2.3=20 feet
and the width of the room according to scale drawing will be:
69÷2.3=30 feet
We know that the wall is in the shape of a rectangle.
This means that the area of scale drawing will be:
Length×Width
= 20×30
= 600 square feet.

The teacher sets up 7 work stations in each of the 2 classrooms.
Step-by-step explanation:
1. Find the number of work stations in all. We can find the number of work stations by dividing the amount of clay by the amount of clay that will be in each work station. 7/8 is the amount she has and 1/16 is how many that will be in each work station. 7/8 divided by 1/16 is equal to 7/8 * 16/1, and if you cross cancel, you would get 14.
2. Find how many are in each classroom. Since we know that we have 14 workstations in all, and that there are two classrooms, to find the amount in each, you have to divide 14/2. 14/2 = 7
Answer: The teacher sets up 7 work stations in each of the 2 classrooms.
