les diviseurs de 25 sont des diviseurs de 15. Vrai ou faux?
Answer:
c'est faux parce que 3 n'est pas un diviseur de 25 et c'est pour 15 so not all divisor of 25 sommes diviseur de 15

Answer:2 2/5
Step-by-step explanation:
answer
2 2/5
Explanation
Divide using long division. The whole number portion will be the number of times the denominator of the original fraction divides evenly into the numerator of the original fraction, and the fraction portion of the mixed number will be the remainder of the original fraction division over the denominator of the original fraction.

A backpack is on sale for 15% off the original price of $39.99. What is the sale price?
Answer:
33.99
Step-by-step explanation:
multiply the original by 100-the sale percentage
(100-15 = 85
.85x39.99
Answer:
$33.99
Step-by-step explanation:
We are given that we have 15%.
What this means is that we subtract 15% from 100%.
Doing that we get 1.00 - 0.15 = 0.85
Therefore the price equals $39.99 * 0.85
The final price is $33.99

After winning a soccer game, the coach took the team out for ice cream cones. He spent $21 on 12 single-scoop ice cream cones. If all the ice cream cones cost the same amount, what was the cost of one ice cream cone?
Answer:
Unitary cost= $1.75
Step-by-step explanation:
Giving the following information:
He spent $21 on 12 single-scoop ice cream cones.
To calculate the unitary cost, we need to use the following formula:
Total cost= number of units*unitary cost
Unitary cost= total cost / number of units
Unitary cost= 21 / 12
Unitary cost= $1.75

Given a polynomial f(x), if (x − 3) is a factor, what else must be true?
f(3) = 0
f(−3) = 0
f(0) = 3
f(0) = −3
Answer:
A
Step-by-step explanation:
Recall that according to the Polynomial Remainder Theorem, if we divide a polynomial f(x) by a binomial in the form (x - a), then the remainder will be f(a).
And by the Factor Theorem, in order for a binomial (x - a) to be a factor of a polynomial f(x), the remainder must be 0. In other words, f(a) = 0.
We are given a polynomial f(x) and that (x - 3) is a factor.
Therefore, a = 3.
And since it is a factor, by the Factor Theorem, the remainder must be 0.
Therefore:
[tex]f(3)=0[/tex]
The answer is A.
Answer:f(−3) = 0

Which color's observed frequency is closest to its expected frequency?
red
blue
green
O yellow
Answer:
Blue
Step-by-step explanation:
Expected frequency is:
red 10/40 = 1/4 = 0.25 = 25%
blue 10/40 = 1/4 = 0.25 = 25%
yellow 10/40 = 1/4 = 0.25 = 25%
green 10/40 = 1/4 = 0.25 = 25%
Observed Frequency is:
red 1/7 = 0.14 = 14%
blue 2/7 = 0.28 = 28% √
yellow 4/7 = 0.57 = 57%
green 0/7 = 0.00 = 0%
Triangle GHK has an area of m square units. If the height of the triangle is increased to five times the current height, and the length of the base increased to four times the current length, what will be the area of the larger triangle?
Answer:
20m square units
Step-by-step explanation:
The area of a traingle = bh/2............... Equation 1
Where b = lenght of the base, h = heigt of the triangle.
From the question,
The area of triangle GHK = m square units., let the base and the heigth of the triangle be x and y respectively
Therefore,
b = x, h = y
Substitute these values into equation 1
m = xy/2................... Equation 2
If the height of the triangle increase to five times the current height, and the length of the base increase to four times the current length.
Therefore,
height of the larger triangle = 5y, base of the larger triangle = 4x
Substitute these values into equation 1
Area of the larger triangle = (5y×4x)/2
Area of the larger triangle = 20xy/2................. Equation 3
Substitute equation 2 into equation 3
Area of the new triangle = 20m square units.

Peter says that 3/4 of a pizza is always the same as 6/8 of a pizza. Nadia says that while they are equivalent fractions, 3/4 and 6/8 of a pizza could represent different amounts. Use a counter example to explain who is correct. Please I need your help. If you help you are nice and god will protect you forever.
Answer:
Nadia
Step-by-step explanation:
6/8 is 3/4 and both are 75% of a pizza but, the eighths of a pizza is a smaller slice of pizza.
4/4 is four slices of pizza
8/8 is eight slices of pizza
They are different amounts.
Mrs. Hooper teaches piano lessons 5 days a week. She teaches for a total of 3 hours per day. How many minutes does she teach each week?
Answer:
900 minutes a week
Step-by-step explanation:
60 minutes makes one hour
3 hours multiplied by 60 minutes is 180 minutes
180 minutes multiplied by 5 days is 900 minutes
Step-by-step explanation:
3 hours *60 minutes= 180 minutes
And if he teaches for 180 mins a day, then in 5 days he will teach:
180 mins*5 days= 900 mins

A paper container in the shape of a right circular cone has a radius of 3 inches and a height of 8 inches. Determine and state thr number of cubic inches in the volume of the cone, in terms of π.
Given:
Radius of the cone = 3 inches
Height of the cone = 8 inches
To find:
The volume of the cone, in terms of π.
Solution:
We know that, the volume of a cone is:
[tex]V=\dfrac{1}{3}\pi r^2h[/tex]
Putting [tex]r=3,h=8[/tex], we get
[tex]V=\dfrac{1}{3}\pi (3)^2(8)[/tex]
[tex]V=\dfrac{1}{3}\pi (9)(8)[/tex]
[tex]V=\dfrac{72}{3}\pi [/tex]
[tex]V=24\pi [/tex]
Therefore, the volume of the cone is [tex]24\pi[/tex].
