Answer: Each friend got 3 cookies.
Step-by-step explanation:
Johann gets three cookies so 24-3=21. Divide it by the seven friends that came. 21/7=3 cookies.
Answer:
Step-by-step explanation:
So 7 of his friends came to the party and 3 cookies were left for himself. To find how many cookies each friend got, first subtract the 3 cookies Johann has from the total.
24-3=21
Then divide 21 by the number of friends.
21÷7=3
So each friend got 3 cookies.
Jessica decides to mix grades of gasoline in her truck. She puts in 8 gallons of regular and 8 gallons of premium for a total cost of $41.04. If premium gasoline costs $0.21 more per gallon than regular, what was the price of each grade of gasoline?
Answer:
The price of the regular gasoline is $2.46, while the premium is $2.67.
Step-by-step explanation:
Let the price of regular gasoline be "x", while the price for the premium be "y", The sum of the amount of each type of gas multiplied by its cost should be equal to the total paid, therefore:
[tex]8*x + 8*y = 41.04[/tex]
We also know that the premium gas costs 0.21 more than the regular one, therefore:
[tex]y = x + 0.21[/tex]
We can apply the second expression on the first, in order to solve for "x".
[tex]8*x + 8*(x + 0.21) = 41.04\\8*x + 8*x + 1.68 = 41.04\\16*x = 41.04 - 1.68\\16*x = 39.36\\x = \frac{39.36}{16} = 2.46[/tex]
[tex]y = 2.46 + 0.21 = 2.67[/tex]
The price of the regular gasoline is $2.46, while the premium is $2.67.

I NEED AN ANWSER ASAP,, PLS AND THANK YOUU When finding a pattern for the sum of two times a number, n, and four less than three times the same number, Cole does the following calculation and decides the pattern is 3n. Show why he is wrong. and write the correct pattern to coles work
n=2
2(2)+3(2)-4=6
Answer: find the answer in the explanation
Step-by-step explanation:
Two times a number, n that is, 2n
and four less than three times the same number, that is, 3n - 4
Cole is wrong for not interpreting the two statement differently into two separate expression.
Finding the sum of the two expression will be
2n + 3n - 4 = 5n - 4
So, if n = 2
Substitute 2 for n in the expression 5n -4
5(2) - 4
10 - 4 = 6
An animal shelter houses dogs, cats, and ferrets. There are 144 animals at the shelter. Of the animals, one fourth are dogs. Eight ninths of the remaining animals are cats. How many of the animals are ferrets?
Answer:
12
Step-by-step explanation:
1 - 1/4 = 3/4 (remaining animals which are cats and ferrets)
1 - 8/9 = 1/9 (means 1/9 of the remaining animals are ferrets)
1/9 x 3/4 = 1/12 (means 1/12 of the animals are ferrets)
1/12 x 144 = 12 ferrets

What is the image of (9,-5) after a dilation with the scale factor of 2.5?
O (23, 12)
O (22.5, -12.5)
O (-22.5, 12.5)
O (18, 12)
Answer:
(B) (22.5, -12.5)
Step-by-step explanation:
When the point [tex](9,-5)[/tex] is dilated by with a scale factor of 2.5
In a dilation, when its scale factor is less than 1, the pre-image will be lesser than the image.
However, when the scale factor is greater than 1, the pre-image will be greater than the image.
The Image of the dilation of [tex](9,-5)[/tex] with a scale factor of 2.5 is therefore:
[tex](9*2.5,-5*2,5)\\=(22.5, -12.5)[/tex]

StartFraction x + 5 Over x + 2 EndFraction minus StartFraction x + 1 Over x squared + 2 x EndFraction
Answer:
[tex]\frac{x^2+4x-1}{x(x+2)}[/tex]
Step-by-step explanation:
Given
[tex]\frac{x+5}{x+2}[/tex] - [tex]\frac{x+1}{x^2+2x}[/tex] ← factor denominator
= [tex]\frac{x+5}{x+2}[/tex] - [tex]\frac{x+1}{x(x+2)}[/tex]
We require the fractions to have a common denominator.
Multiply numerator/denominator of first fraction by x
= [tex]\frac{x(x+5)}{x(x+2)}[/tex] - [tex]\frac{x+1}{x(x+2)}[/tex]
Subtract terms on numerator leaving the common denominator
= [tex]\frac{x^2+5x-x-1}{x(x+2)}[/tex]
= [tex]\frac{x^2+4x-1}{x(x+2)}[/tex]

The radius of a circle is 12 in. What is the circle's diameter?
Answer:
24 in
Step-by-step explanation:
The diameter of a circle is twice its radius which is 12 * 2 = 24.
Answer:
The diameter is 24 inches
Step-by-step explanation:
The radius of a circle is 1/2 of the circles diameter
r = d/2
d = 2r
d = 2*12
d = 24
The diameter is 24 inches

−→− bisects ∠DGF, m∠DGE=53∘. Find m∠DGF.
1. what is the measure of angle DBF? (image included below)
Answer:
Measure of angle DBF = 106°.
Step-by-step explanation:
Given in the question,
m∠DGE = 53°
and line segment GE is the angle bisector of ∠DGF.
Since segment GE is the angle bisector of ∠DGF that means it divides the angle DGF into two equal parts.
Therefore, m∠DGE ≅ m∠FGE
m∠DBF = m∠DGE + m∠FGE
m∠DBF = 2(m∠DGE)
= 2(53)°
= 106°
Therefore, measure of angle DBF = 106°.

Point A is the incenter of ΔDEF. Point A is the incenter of triangle D E F. Lines are drawn from the points of the triangle to point A. Lines are drawn from point A to the sides of the triangle to form right angles and line segments A X, A Y, and A Z. Angle L D A is 27 degrees. Angle A D M is (3 n minus 6) degrees. What is the value of n? 7 11 14 15
Answer:
The correct option is;
11
Step-by-step explanation:
The incenter is the point where the interior angle bisectors of the triangle meet, hence the interior angles are each bisected into two by the segments DA, EA, and FA respectively
Given that point A is the incenter of ΔDEF, we have;
∠FDE = ∠XDY is bisected by DA which gives ∠XDA = ∠YDA
∠LDA = ∠XDA = 27
∠MDA = ∠YDA = 3··n - 6
Therefore, 27 = 3·n - 6
3·n = 27 + 6 = 33
n = 33/3 = 11°

Answer:
Answer B (proportional)
Step-by-step explanation:
The variable y and x are related by the constant of proportionality "6" in the expression
y = 6 x
Such means that if x adopts whatever value, y is always proportional to that x-value, by the multiplicative factor 6.
y is proportional to x via the proportionality constant (it has to be always a multiplicative constant) "6"

Which of the following best represents the relationship between angles x and y?
A) x = y
B) x = 180°-y
C) y = 180°-6
D) x = 2y
