Joan has a piece of material for making a costume. She needs to cut it as shown. What is the angle measure of the piece left over?
Answer:
50 degrees
Step-by-step explanation:

90 - 40 = 50
we have 50 degrees.

Apple and cranberry juice are mixed in a ratio of 5 to 3. What amount of each juice would be needed to make a 64-fluid ounce pitcher of apple-cranberry juice?
Answer:
32
Step-by-step explanation:
64/2=32
Answer:
[tex]\text{Apple juice needed: }40\:\mathrm{oz},\\\text{Cranberry juice needed: }24\:\mathrm{oz}[/tex]
Step-by-step explanation:
Let [tex]a[/tex] be the amount of apple juice needed, in ounces. Let [tex]c[/tex] be the amount of cranberry juice needed, in ounces. We can set up the following system of equations:
[tex]\begin{cases}a=\frac{5}{3}c, \\a+c=64\end{cases}[/tex]
Solving, we get:
[tex]\frac{5}{3}c+c=64,\\\\\frac{8}{3}c=64,\\\\c=\frac{64\cdot 3}{8}=\boxed{24\:\mathrm{oz}}[/tex]
[tex]a=\frac{5}{3}c,\\\\a=\frac{5}{3}(24),\\\\a=\boxed{40\:\mathrm{oz}}[/tex]
How do you multiply a fraction by a whole number?
Multiply the top number of the fraction by the whole number and then place that over the lower number of the fraction. Then you can see if the new fraction can be reduced or rewritten as a proper fraction.
Example:
1/2 x 3 would be (1 x3) / 2 = 3/2 which can be rewritten as 1 1/2
Example: [tex]\frac{2}{5}*10=\frac{2}{5}*\frac{10}{1}=\frac{20}{5}=4[/tex]

Step-by-step explanation:
All numbers belong to the set of numbers known as the real number system. The real number system consists of
every number you have ever dealt with since you were old enough to count. The numbers in the real number system
are divided into two main groups. One group is called the rational numbers and the other is called the irrational
numbers. The set of irrational numbers consists of all numbers that are not rational. This set of irrational numbers
includes those numbers that cannot be written as the ratio of two integers, non-remediate numbers.
and decimals that do not have a repeating pattern of digits. For example, pi(π),
√
2,−2.345876921... are irrational
numbers.
The set of rational numbers includes natural numbers, whole numbers, integers, numbers that can be expressed as
the ratio of two integers, a decimal number that terminates, and decimal numbers that have a repeating pattern of digits.
The natural numbers are the set of positive integers. For example, 1, 2, 3. . . are all natural numbers. The whole
numbers are the natural numbers and zero. For example, 0, 1, 2, 3. . . are all whole numbers. The integers are
the whole numbers and their opposites. For example, -2, -1, 0, 1, 2. . . are all integers. A rational number is any
number that can be expressed in the form of a
b where b 6= 0. When a rational number is expressed as a decimal, it
decimal will terminate (end) or For example, 1
2
,
√
81,−7.456 545 654 are
all rational numbers.
When you classify numbers remember that they can often belong to more than one set of numbers. If you think of
the number 3, you can call it a natural number, a whole number, an integer and a rational number.
The following table may help you to better understand the real number system.
A. -9 1/2
B. 1 1/2
C. 2 1/2
D. 10 1/2

2(2.5x + 8) = 11
Step-by-step explanation:
2×2.5x+2×8=11
5x+16=11
5x=11-16
5x=-5
x=-1
Answer:
x = -1
Step-by-step explanation:
2(2.5x + 8) = 11
Divide both sides by
2.5x + 8 = 5.5
Subtract 8 from both sides
2.5x = -2.5
Divide both sides by 2.5
x = -1

Sofia is a helper for the kindergarten class and is in charge of picking a video for their end-of-year party. To choose which type of movie they would like best, she decided to survey every other child entering a matinee for a cartoon called, “Three Pretty Princesses.” The total number of children surveyed was 40. What is wrong with the way she selected her sample? Check all that apply.
The sample of 40 children is too small to represent all kindergartners.
The sample was taken at a specific movie, which will skew data towards that type of movie.
The sample is likely to include a lot more girls than boys, since the movie title is “Three Pretty Princesses.”
The sample should include the adults with the children instead of only children.
The sample should include the other peer helpers in her grade to include a greater age range.
Answer:The sample was taken at a specific movie, which will skew the data towards that type of movie.
Step-by-step explanation:
Jason has sport cards in his pocket. He has three football cards, one wrestling card and two baseball cards. If Jason reaches into his pocket and selects one card, what is the probability he will get a baseball card? Show your answer in lowest terms.
Answer:
In lowest terms, there is a 1/3 probability of Jason pulling out a baseball card.
Step-by-step explanation:
There are a total of 6 cards. 4/6 of them are football and wrestling which results in 2 baseball cards. So the probability is 2/6 but since the question wants it in lowest terms, you would have to simplfy 2/6. Divide the top by 2 and the bottom by 2 which gets you 1/3.

Step-by-step explanation:
To divide up whole numbers by fractions, you simply need to just multiply the whole number by the reciprocal of the fraction. in other words, flip the fraction.
Ex.
12 ÷ 1/4
=
12 x 4
Ex. 2
12 ÷ 1/2

Answer: 12?????? i dont know what the question is saying bc ur took a picture of something too close maybe get the whole question?
Step-by-step explanation:
Part A
y varies directly with x, so we know that y = kx for some constant k. Why the letter 'c' isn't used as a constant, instead of k, I'm not entirely sure.
We're told that x = 0.5 and y = 36. Let's use those values to find k
y = kx
36 = k*0.5
36/0.5 = k
72 = k
k = 72
The equation y = kx updates to y = 72x
As a check, plug x = 0.5 in to get,
y = 72x
y = 72*0.5
y = 36
which helps show that we have the correct equation.
Answer: y = 72x===============================================================
Part B
If y = 1/3, then,
y = 72x
1/3 = 72x
72x = 1/3
x = (1/3)*(1/72)
x = (1*1)/(3*72)
x = 1/216
Note how I multiplied both sides by 1/72, which is the same as dividing both sides by 72.
Answer: x = 1/216Please answer question below
