Solve f(x)= x2 when x = 5.
Answer:
10
Step-by-step explanation:
Answer:
f = 2Step-by-step explanation:
f(x) = x2 ... when 'x' is equal to 5
So...
1.) Plug in 5 for the variable 'x'
f(5) = (5) * (2)
2.) Simplify both sides of the equation
5f = 10
3.) Divide both sides by 5
5f /5 = 10/5
f = 2

A large pizza at Palanzio's Pizza starts at $6.80 with a $0.90 charge per extra topping. A large pizza a Guido's Pizza starts at $7.30 with a $0.65 charge per extra topping. How many toppings will need to be added for the price of the pizzas to be the same?
Answer:
Palanzio's Pizza: Y= .90x+6.80
Giudo's Pizza: Y= .65x+7.30
.90x + 6.80= .65x + 7.30
.25x + 6.80= 7.30
.25x = .50
x = 2
At a school cafeteria a cold lunch costs $1.80, and a hot lunch costs $3.00. During one school year a teacher spent

than twice the number of hot lunches the teacher bought.
Which system of equations can be used to find c, the number of cold lunches, and h, the number of hot lunches, the
teacher bought during the school year?
(16/25)-3/2 help me solve
Answer:
-43/50
(decimal) = -0.86
Step-by-step explanation:
Find the LCD which is 50.
16/25 will be multiplied by 2 (because 25 x 2 = 50) so it will then equal 32/50
3/2 will be multiplied by 25 (2 x 25 = 50) = 75/50
subtract them which will give you -43/50

Answer:
(4²πx2) + (8π x 4) = 201.061... OR 64π
Answer:
Step-by-step explanation:
5) r = 8/2 = 4 cm
Top and bottom = 2*πr²
= 2 * 3.14 * 4 * 4
= 100.48 cm²
Middle part = h * πd
= 4 * 3.14 * 8
= 75.36 cm²
Total = 100.38 + 75.36 = 175 .84 cm²
NEED HELP ASAP GIVING 33 POINTS AND PLZ SHOW WORK DONT DO 7-8
Answer:
1) 1924m²
2) a = (b x h) / 2
(5 x 12) = 60
60 / 2 = 30in²
30in² x 2 = 60in²
area of upper rectangle =
a = l x w
13 x 8 = 104in
area of backer rectangle =
a = l x w
12 x 8 = 96in
60in² + 104 + 96 = 260in²

What are m∠1 and m∠2?
A.m∠1 = 30°, m∠2 = 35°
B.m∠1 = 35°, m∠2 = 30°
C.m∠1 = 65°, m∠2 = 60°
D.m∠1 = 85°, m∠2 = 80°
Answer:
B
Step-by-step explanation:
First find the third angle straight linear make 180° so
180°-115°=65°
So 80°+65°+X=180°..triangle measure 180°
145°+X=180
X=180-145
X=35°
The second one. Again straight linear measure 180° so
180°-115°=65°
65°+85°+ Y=180°
150°+ Y=180°
X=180°-150°
Y=30°

Mary wants to do a cheesecake. She needs 4 1/2 cups of sweet cream. She knows that 1
cup = 8 ounces How many ounces does she need?
Plsss 50 points!?
Answer:
36 ounces
Step-by-step explanation:
If 1 cup equals 8 ounces, you would multiply 4 1/2 by 8. 8 x 4 is 32 (ounces), and half of 8 is 4, so 4 ounces. You would then add 32 and 4 together to get your answer. Hope this helps!!
Answer:
She needs 36 ounces.
Step-by-step explanation:
4 1/2=9/2
1/8=(9/2)/x
cross product
8(9/2)=1*x
72/2=x
x=36

How would I do this?
Answer:
Refer to explanation..
Step-by-step explanation:
Since x represent same number when if it is used multiple times..
40 - 3 - 3 = 34 (Find out how many is 4 x)
4x = 34
X = 34 ÷ 4 = 8.5
I don't know what the question is finding for, if it's breadth then it's 8.5, if it is finding length..
Length = 8.5 + 3 = 11.5

Answer:
3.6 hours
Step-by-step explanation:
The computation of the number of hours will the battery last is given below:
Given that
The capacity of her battery is 2 by 5
And, it declines 1 by 9 for every hour
So,
[tex]= \frac{2}{5}\times \frac{9}{1}\\\\= \frac{18}{5}\\\\= 3\frac{3}{5}[/tex]

Find the mean and median travel times for these students.
If necessary, round your answers to the nearest tenth
Mean: _ minutes
Median: __ minutes
Answer:
mean: 65
median: 9
Step-by-step explanation:
You take all the numbers you have and add them up. Make it simple by adding smaller numbers together. Then once you have the total which is 65 you divide it by the total of numbers you have and then round because after dividing you get 8.125 and the safest way to round is to 9.

During a test flight, Jeri's rocket reached a height of 18 yards. This was 7 yards less than the height of Devon's rocket. Write and solve a subtraction equation to find the height of Devon's rocket.
Answer:
23 yards
Step-by-step explanation:
During a test flight, Jeri's rocket reached a height of 18 yards. This was 7 yards less than the height of Devon's rocket. Write and solve a subtraction equation to find the height of Devon's rocket.
Let us represent the height of Devon's rocket = x
18 yards = x - 7 yards
x = 18 yards + 7 yards
x = 23 yards
The height of Devon's rocket = 23 yards
