3 pizzas for $24.99_______________ cost of each pizza
Answer:
$8.33
Step-by-step explanation:
24.99 ÷ 3 = 8.33
Answer:
$ 8.33
Step-by-step explanation:
If 3 pizzas cost $24.991 pizza will now cost [tex] \frac{24.99}{3} [/tex] 1 pizza costs $8.33Steven needed to mail a holiday envelope to his Aunt Linda. He used $0.02 stamps and $0.10 stamps to mail the gift. If he used 15 stamps worth $0.78, how many of each type of stamp did he use?
Answer:Steven used 9 $0.02 stamps and 6 $0.10 stamps
Step-by-step explanation:
let number of $0.02 stamp be =x
let number of $0.10 stamp be =y
so that the number of stamps used can be expressed as
x+y=15
and the total price of stamps used equaling $0.78 be expressed as
0.02x + 0.10y =0.78
Solving
x+y=15----1
0.02x + 0.10y =0.78---2
from equation 1 , x =15-y, putting the value of x into equation 2
0.02(15-y) + 0.10y =0.78
0.3 -0.02y + 0.10y = 0.78
0.3 + 0.08y=0.78
0.08y=0.78-0.3
y=0.48/0.08 =6
y =6 stamps
Putting bthe value of y =6 into equation 1
x+6=15
x=15-6 =9
Steven used 9 $0.02 stamps and 6 $0.10 stamps
For the equation W = -175t + 8,750, how much water is left after 6 hours?
Answer:
7,700
Step-by-step explanation:
-175 x 6 = -1,050
-1,050 + 8,750 = 7,700
write the division expression and in words and as a fraction: ( g + 12) ÷ h
Answer:
The sum of g and 12 divided by h. As a fraction it would be: [tex]\frac{g+12}{h}[/tex]

Here is a different function modeling the height of a
potato, in feet, seconds after being fired from a different
device:
-161? + 80t +64
How could you determine the time at which the potato
hits the ground? You do not need to determine the
answer. Just explain HOW you would go about
doing so.
Submit
Answer:
An object is thrown straight up from the top of a building h feet tall with an initial velocity of v feet per second. The height of the object as a function of time can be modeled by the function h(t) = –16t2 + vt + h, where h(t) is the height of the object (in feet) t seconds after it is thrown.
Step-by-step explanation:
A ball is thrown straight up from the top of a 128 foot tall building with an initial speed of 32 feet per second. The height of the ball as a function of time can be modeled by the function h(t) = –16t2 + 32t + 128. How long will it take for the ball to hit the ground?

Which of the following is a factor of 21?
Answer:
The factors of 21 are 1, 3, 7 and 21. A factor is a number that can divide evenly into a given number. Because 21 can be divided by numbers other than itself and 1, it is called a composite number. Every number has 1 and itself as a factor. Numbers that have no other factors are called prime numbers.
Step-by-step explanation:
What is the surface area of this design?
PLEASE HELP ASAP!!
SO you would have to first have the surface area of the cube which is 25 for each side so 25 x 6 = 150
Then you find the surface area for the other sides and It is 4 x 5 divided by two for each triangle on the side, so that would be 20 and you multiply then 6.4 x 5 to equal 32 for the rectangle. The last part is the bottom and it is 4 x 5 again which is 20 so then you add them all up but im not sure.

A marble is selected at random from a jar containing 30 red marbles, 10 yellow marbles, and 60 green marbles. Find the theoretical probability that it is either red or green.
there is a 90% chance its a red or green or a 90/100 chance
Step-by-step explanation:
first you need to count your whole which would be the sum of adding all the marbles which is 100 then add the red and green that's 90 lastly you make a fraction 90/100 (simple the fraction if asked )
Michelle and Natasha each had to repair their new iPhones. The initial cost of each repair is $100. Michelle and Natasha each have two discount coupons. Each of them uses both coupons toward the cost of the repair. One coupon is for $25 off the repair cost and the other coupon is for 20% off the repair cost. Michelle and Natasha use their coupons in a different order, as shown below.
Michelle uses the 20% off the repair cost coupon first. She then uses the $25 off the repair cost coupon on the remaining balance.
Natasha uses the $25 off the repair cost coupon first. She then uses the 20% off the repair cost coupon on the remaining balance.
Who paid the least amount of money for the iPhone repair?
Answer:
natasha paid the least amount

is 628/1300 the same as 628 divided by 1300?
Answer:
Step-by-step explanation:
Yes
Answer:
yes
Step-by-step explanation:
here 628/1300 means
[tex] \frac{628}{1300} [/tex]
where
[tex] \frac{628}{1300} means 628 \div 1300[/tex]
where the sign ÷ shows divide
so we can say 628/1300=628 divided by 1300
hope it helps you

Dairy cows provide 90% of the world's milk supply. The
table shows the amount of milk produced by a cow over
time. If the pattern in the table continues, how much milk
can a farmer get from a cow in 1 year (365 days)?
Answer:
9,125 L
Step-by-step explanation:
The computation of the milk that can a farmer would get from a cow in one year is shown below:
As in the table it is shown that
In 2 days, the amount of milk is 50 L
In 7 days, the amount of milk is 175
and so on
So if we can see that the number of days should be multiplied by 25 to get the liters
So for 365 days, the milk would be
= 365 days × 25
= 9,125 L
Alex is conducting a survey for a car company. She decides to start by interviewing some people in her neighborhood. She prepares a questionnaire and emails it to 50 neighbors who own cars. Of those neighbors, 24 respond. Why is this sample likely to be biased?
A.
Alex sent a questionnaire by email instead of going door to door.
B.
Alex sent the questionnaire only to those who live near her.
C.
Not everyone who got the questionnaire responded.
D.
Those who got the questionnaire may not have responded on time.
Answer:
The answer is B
This is because if we know that Alex sent the questionnaire only to those who live near her, we can infer that this is biased.
Answer:
B: Alex sent the questionnaire only to those who live near her

Consider a car rental for $42, plus $0.22 per mile driven. Which statements are correct?
A) This situation is modeled by a linear function.
B) If the car is driven 200 miles, the rental will cost $86.
C) If the car is driven 500 miles, the rental will cost $142.
D) This situation can be modeled by the function f(x) = 0.22x + 42.
E) This situation can be modeled by the function f(x) = (0.22)X + 42.
Answer:
a, b and d
Step-by-step explanation:
200 miles x 0.22 = 44$ + 42$= 86$
the equation would be f(x)= 0.22x + 42.
and its linear.
