6 3/4 yards of fabric per 3 costumes. how many yards do i need for 7 costumes
Finds how much is needed for 1 costume by dividing 6 3/4 by 3
6 3/4 /3 = 2 1/4 yards per costume.
Multiply yards per costume by 7:
2 1/4 x 7 = 15 3/4 yards total needed.
[tex]\\ \rm\hookrightarrow 6\dfrac{3}{4}yards=3costumes[/tex]

An exponent is added to a term when the term is multiplied by itself. The exponent s value is the number of times the term is multiplied by its self.
There are 2 a’s so a x a = a^2
There are 3 b’s so you have b^3
There are 2 c’s so it is c^2
The equation becomes: a^2 x b^3 x c^2
Answer:
[tex]a \times a \times b \times b \times b \times c \times c = {a}^{2} \times {b}^{3} \times {c}^{2} \\ thank \: you[/tex]

does this form a right triangle 8,10,6
Answer:
Yes, it does. We can check by using the Pythagorean theorem (P.t.).
P.t.: a^2 + b^2 = c^2
a = 6, b = 8, c = 10
6^2 + 8^2 = 10^2
36 + 64 = 100
100 = 100
Brainliest, please!
Answer:
Step by step answer.
Yes
a^2 + b^2 = c^2
8^2 + 6^2 = 10^2
64 + 36 = 100
100 = 100
The Pythagorean Theorem works. C is always assumed to be the hypotenuse because it is the longest line It's position does not matter. If you did the problem like this
6^2 + 10^2 = 8^2
Of course this would not work, but it would also disobey the convention that c is the longest side.
Tyron made 60 cakes. He gave 20% of his cakes to Ana . And 1/6 of his cakes to Dora. What fraction of the 60 cakes does he have left?
Answer:
19/30
Step-by-step explanation:
Total cakes made by Tyron = 60
Cakes given to Ana = 20% of 60
[tex]=\dfrac{20}{100}*60\\\\= 2*6\\\\= 12 \ cakes[/tex]
Number of cakes given to Dora= [tex]\dfrac{1}{6}*60=10[/tex]
Remaining cakes = 60 - ( 12 +10)
= 60 - 22
= 38 cakes
Fraction of left cakes = [tex]\dfrac{38}{60}=\dfrac{19}{30}[/tex]

Write a function C(t) to represent the cost of
renting a canoe for t hours. The rental charge
is $25 plus $2 for every 20 minutes of rental.
Find C(1.5) and describe its meaning.
Answer:
C(t)=25+2t
C(1.5)=25+2(1.5)=28
$28 for 1.5 minutes rent
A function C(t) represents the cost of renting a canoe for t hours is C(t)=25+2t and the cost for 1.5 minutes will be $28.
What is a function?
A function is defined as the expression that set up the relationship between the dependent variable and independent variable. A function in mathematics from a set X to a set Y allocates exactly one element of Y to each element of X. The sets X and Y are collectively referred to as the function's domain and codomain, respectively.
Given that the rental charge is $25 plus $2 for every 20 minutes of rental.
The function formed for the given data will be:-
C(t)=25+2t
At 1.5 minutes the rent will be calculated as below:-
C(1.5)=25+2(1.5)=28
Therefore, the function C(t) represents the cost of renting a canoe for t hours is C(t)=25+2t, and the cost for 1.5 minutes will be $28.

You plan to cut a board into 3 pieces to repair part of a railing. You are going to cut the two ends of the board off into two equal pieces that are 1.1 feet long, if the remaining piece needs to be 2.30 times longer than the each of the first two cuts what length board should you buy? Round to the nearest tenth.
Answer:
The board should be 4.7 feet long.
Step-by-step explanation:
To find the remaining piece, you just multiply 1.1 by 2.3 which is 2.53. That's the length of the remaining piece.
Then you add all the pieces together.
1.1+1.1+2.53 =
4.73
Round and add label.

Using a Table to find the Constant of Proportionality
his table represents a proportional relationship. Use the table to identify the constant of proportionality between the
atio of the number of laps to the number of swimmers,
Answer:
k = 12
Step-by-step explanation:
The constant of proportionality k is the ratio
k = [tex]\frac{laps}{swimmers}[/tex]
Use any ordered pair from the table to find k
Using number of laps = 240, number of swimmers = 20 , then
k = [tex]\frac{240}{20}[/tex] = 12
V=1/3πr²(h-1) find h
Answer:
[tex]h=\displaystyle \frac{3V}{\pi r^2}+1[/tex]
Step-by-step explanation:
Hi there!
[tex]V=\displaystyle\frac{1}{3} \pi r^2(h-1)[/tex]
Divide both sides by [tex]\displaystyle\frac{1}{3} \pi r^2[/tex]:
[tex]\displaystyle \frac{V}{\displaystyle\frac{1}{3} \pi r^2}=(h-1)[/tex]
[tex]\displaystyle \frac{3V}{\pi r^2}=h-1[/tex]
Add 1 to both sides:
[tex]\displaystyle \frac{3V}{\pi r^2}+1=h[/tex]

Hey there! I'm happy to help!
Our goal here is to write the function (equation) that represents what Carlos has graphed. This is a line, so we can use the slope-intercept equation to represent it.
Our slope-intercept equation is y=mx+b, where m is the slope and b is the y-intercept.
If we look at the graph, we see that the the line intersects the y-axis at the point (0,0), also known as the origin, so our y-intercept is 0.
To find our slope, we need to first find two points on the line. Well, we already have (0,0). The next point on the line that seems to have integers is (7,5). This means that from (0,0) our rise is 5 and our run is 7, and since slope is rise over run, that means that our slope is 5/7 (for every one unit we go over, the line goes up 5/7).
Now, we just throw these numbers into the equation.
y=5/7x
or
f(x)=5/7x (if it needs to be in that function format)

(x+1)(x−5)
Answer:
see below
Step-by-step explanation:
f(x) = -2/3 (x+1) (x-5)
First find the zeros
0 = -2/3 (x+1) (x-5)
Using the zero product property
x+1 =0 x-5=0
x= -1 x = 5
Then find the y intercept
y = -2/3 (0+1)(0-5)
- 2/3 (1)(-5)
+10/3
We know that this is a parabola that opens downward
Simplify
y=-2/3(x+1)(x-5)y=-2/3(x(x-5)+x-5)y=-2/3(x²-5x+x-5)y=-2/3(x²-4x-5)Graph attached
