Water / 2
If there are 245 seventh-graders in the school, how many can be expected to prefer chocolate milk?
A: 45
B: 84
C: 90
D: 105
Answer:
D
Look at the picture. :)
105 can be expected to prefer chocolate milk
How to Solve the Problem?The problem can be solved in following steps.Survey of seventh-grade students in the lunch-line is given in chart.We need to calculate the expected students to prefer chocolate milk
Let the expected students be x
Calculate the total students = 15+12+6+2 = 35
The expected students prefer milk is
15/35 = x/245
245*15=35x
3675 = 35x
x = 3675 / 35
x = 105
Hence 105 students are expected to prefer chocolate milk .

solve for h in the literal equation g(h+3/2)=5
Answer: h= 5/g−3/2
Step-by-step explanation:
h= 5 over g minus 3 over 2
Answer:
[tex]h\neq -3/2[/tex]
Step-by-step explanation:
Divide both sides by h+3/2;
g(h+3/2)/h+3/2=5/h+3/2

Solve for x:
5x - 3y = 22
10x - 4y = 46
Answer:
x=5, y=1
Step-by-step explanation:
Isolate x for 5x-3y=22
5x-3y=22
Add 3y to both sides
5x-3y+3y=22+3y
Simplify
5x=22+3y
Divide both sides by 5
5x/5=22/5+3y/5
Simplify
x=22+3y/5
Substitute x=22+3y/5
10*22+3y/5-4y=46
Simplify 10*22+3y/5-4y
10*22+3y/5=2(3y+22)
=2(3y+22)-4y
Expand 2(3y+22)
=6y+44-4y
Simplify 6y+44-4y
=2y+44
Isolate y for 2y+44=46
2y+44=46
Subtract 44 from both sides:
2y+44-44=46-44
Simplify
2y=2
Divide both sides by 2;
2y/2=2/2
Simplify;
y=1
For x=22+3*1/5 substitute y=1
y=22+3*1/5
22+3*1=25
=25/5
Divide the numbers;25/5=5
=5
x=5
The solutions to the system of equations are;
x=5, y=1

Step-by-step explanation:
It costs $32 per day to rent a medium-sized car, plus $0.25 for each mile driven over 150 miles. The equation that represents this situation is y = 0.25x + 32, where y represents the total cost of renting a car, and x represents the number of miles driven over 150 miles.
a.) What is the slope and what does it represent in the context of this problem?
b.) What is the y- intercept and what does it represent in the context of this problem?
Answer:
Read explanation
Step-by-step explanation:
A)The slope is the number before the X so 0.25, this represents the amount of money people have to pay for each mile driven over 150 miles.
B) The y-intercept is the number after the X so 32, this number represents the amount people have to pay rent the car before actually using it.

Solve the system of equations.
-3x +y = 2
70 – 8y = 1
Solution:
y =
Answer:
x = -1, y = -1.
Step-by-step explanation:
-3x +y = 2
7x – 8y = 1
We can use the elimination method to solve these:
Multiply the first equation by 8:
-24x + 8y = 16
Now add this to the second equation:
-17x -8y + 8y = 17
-17x = 17
x = -1.
Plug x = -1 into the first equation:
-3(-1) + y = 2
3 + y = 2
y = -1.

Mr. Lisa wants to hang a triangular banner at the entrance of the school. He performs an unknown dilation to include the banner labeled ∆A'B'C' on a sketch. If side A'B' is 8 units, what will be the measure of B'C' if the measure of AB is 24 feet and BC is 6 feet?
Answer:
B'C' = 2 units
Step-by-step explanation:
The dilation performed makes ∆A'B'C' (sketched flag) similar to ∆ABC (actual flag).
Given that, A'B' = 8 units, AB = 24 ft, and BC = 6 ft, therefore:
A'B'/AB = B'C'/BC
Substitute
8/24 = B'C'/6
Cross multiply
24*B'C' = 8*6
24*B'C' = 48
B'C' = 48/24
B'C' = 2 units

please show calculations steps plus this should be solved as a system
Answer:
Boys= 12
Girls= 6
Step-by-step explanation:
Let no: of girls be 'x'
No: of boys= 2x
boys after= 2x-6
girls after = x+6
according to the question,
2(2x-6)=x+6
4x-12=x+6
3x=18
x=6
No: of girls at first= 6
No: of boys at first=2*6=12

Step-by-step explanation:
A diameter spans from one end of (in this case, a circle) to the direct opposite end, going through the center-point. The radius, on the other hand, is half of a diameter, and spans only from the center-point to a point on the circle.
In this case:
1) Diameter = 18 km (given)
Radius = 18/2 = 9 km
2) Diameter = 1 x 2 = 2 m
Radius = 1 m (given)
3) Diameter = 17 x 2 = 34 cm
Radius = 17 cm (given)
4) Diameter = 50 mm (given)
Radius = 50/2 = 25 mm

Answer:
Step-by-step explanation:
Rate of decrease = 3% = 0.03
Number of decreased employees = Current number of employees * rate of decrease * number of years
