What type of number is this?
Answer: c rational
Step-by-step explanation: if it can be a fraction its rational
Answer:
irrational
Step-by-step explanation:
We need to tell which kind of number is π/2 .
Now here π is a Irrational Number. Since it has non terminating and non repeating decimals.
Also when we divide π by 2 , it be irrational only since the multiplication or division of a rational and a Irrational Number is Irrational .Hence π/2 is a Irrational Number.The Frederick county fair cost $15.00 to get in and $2.50 per ride, while the Montgomery county fair cost $10.00 to get in and $3.00 per ride.

In circle D, angle ADC measures (7x + 2)°. Arc AC
measures (8x - 8)º.
What is the measure of angel ABC
Answer:
The measure of angle ABC is 36° ⇒ 1st answer
Step-by-step explanation:
Let us revise some important facts in the circle
The measure of the center angle is equal to the measure of its subtended arc
The measure of the inscribed angle is equal to half the measure of the central angle subtended by the same arc
The vertex of a central angle is the center of the circle and its sides are radii in the circle
The vertex of an inscribed angle is a point on the circle, and its sides are chords in the circle
In circle D
∵ D is the center of the circle
∵ A and C lie on the circle
- DA and DC are radii
∴ ∠ADC is a central angle subtended by arc AC
∴ m∠ADC = m of arc AC
∵ m∠ADC = (7x + 2)°
∵ m of arc AC = (8x - 8)°
- Equate them to find x
∴ 8x - 8 = 7x + 2
- subtract 7x from both sides
∴ x - 8 = 2
- Add 8 to both sides
∴ x = 10
Substitute the value of x in the measure of ∠ADC
∵ m∠ADC = 7(10) + 2 = 70 + 2
∴ m∠ADC = 72°
∵ AB and BC are two chords in circle D
∴ ∠ABC is an inscribed angle subtended by arc AC
∵ ∠ADC is a central angle subtended by arc AC
- By using the 2nd fact above
∴ m∠ABC = m∠ADC
∴ m∠ABC = × 72
∴ m∠ABC = 36°
The measure of angle ABC is 36 degrees
Circle geometry
To get the required measure of m<ABC, we will use the theorem that states that the measure of the central angle is equal to the measure of its subtended arc and;
The vertex of a central angle is the center of the circle and its sides are radii in the circle
According to the given circle D
∠ADC is a central angle subtended by arc AC
m∠ADC = m of arc AC
m∠ADC = (7x + 2)°
m of arc AC = (8x - 8)°
Equate to find the value of x
8x - 8 = 7x + 2
x - 8 = 2
x = 10
Substitute the value of x in the measure of ∠ADC
m∠ADC = 7(10) + 2 = 70 + 2
m∠ADC = 72°
∠ADC is a central angle subtended by arc AC
m∠ABC = 0.5 × 72
m∠ABC = 36°
Hence the measure of angle ABC is 36 degrees

Find the value of y.
Answer:
61 degrees
Step-by-step explanation:
Since one of the sides is 102, the opposite one will be the same.
so,
102+102+95
= 299
The total is 360 degrees
360-299
= 61 degrees

Step-by-step explanation:
The volume of the prism with dimensions 7 in, 11 in and 9 in is 693 cubic inch.
What is a prism ?A polyhedron with two polygonal faces lying in parallel planes and with the other faces parallelograms
It is given that Volume of Prism V = Bh
The variable B stands for the Area of the base and it is given = 11* 9= 99 sq.in
In this prism , h stands for height h = 7 in.
Therefore the volume of the prism is = 7*99=693 cu.in

The manager of the shelter wants the kittens distributed equally among the crates. How might that be done? How many kittens will end up in each crate? Need help fast!!!
Answer:
2 kittens per crate
Step-by-step explanation:
The kittens in a room at an animal shelter are arranged in five crates, as shown.
The manager of the shelter wants the kittens distributed equally among the crates. How might that be done? How many kittens will end up in each crate?
Crate 1 = 2 kittens
Crate 2 = 1 kitten
Crate 3 = 4 kittens
Crate 4 = 3 kittens
Crate 5 = 0 kitten
Total kittens = 2 + 1 + 4 + 3 + 0
= 10 kittens
To distribute them equally among the crates, divide the number of kittens by the number of crates
Kitten per crate = number of kittens / number of crates
= 10 kittens / 5 crates
= 2 kittens per crate
Kitten per crate = 2 kittens per crate

Suppose that 20% of all students in a school make the Honor Roll. Which simulation best models a way to show how
students can be randomly selected and identified as being on the Honor Roll? WHY is that the best simulation?
A) Put 10 marbles in a bag, 8 red and 2 yellow. Draw out a marble at random 100 times, replacing the marble each
time.
B) Divide a spinner into 4 equal parts, labeled 1-4. Spin it 100 times. Let an even number represent Honor Roll and
an odd number represent not on the Honor Roll.
PLEASE REMEMBER TO STATE WHY
Answer:
A)
Step-by-step explanation:
The problem stated that 20 percent got in honor roll.
The key word in the problem is randomly selected.
Out of a and b, it's simply crossing out one of them.
B doesn't make sense, since if you spun a spinner 100 times, each side would have a probability of 25 percent. And that's if you only used one of the parts as an odd number.
Another way to think of it is that there are 2/10 yellow marbles, and 8/10 red.
2/10=20 percent.
8/10=80

Maria is making a fruit punch. There are 15.75 ounces of orange juice in a container. Maria pours 2.25 ounces of cranberry juice into the container each second. How many ounces of fruit punch are in the container after 9 seconds?
Answer:
20.25 ounces
Step-by-step explanation:
We are given 2.25 ounces of cranberry poured into the container per second. We need to find is how much that is after 9 seconds. (Note: This is different from the 15.75 ounces of orange.) There are many ways to solve this question (e.g If 2.25 is 1, then multiply 2.25 and 9 = 20.25) Now to solve this let's set up fractions; let "x" be the variable;
[tex]\frac{1}{2.25}=\frac{9}{x}[/tex]
Apply fraction: if [tex]\frac{a}{b}=\frac{c}{d}\mathrm[/tex] then [tex]a\cdot \:d=b\cdot \:c[/tex] (meaning cross multiply)
[tex]1\cdot \:x=2.25\cdot \:9[/tex]
Simplify
Multiply by 1[tex]1 x = 2 . 2 5 \cdot 9 \\\\ x = 2 . 2 5 \cdot 9[/tex]
Multiply the numbers[tex]x = 2 . 2 5 \cdot 9\\\\x=20.25[/tex]
Therefore, there are 20.25 ounces of fruit pouch in the container after 9 seconds.

Jordon missed 49 on his multiple choice math final and earned a grade of 65%. How many total questions were on the final exam?
Answer:
The exam was out of 75.
Step-by-step explanation:
You know that he earned 65% so more than half his answers were correct.
Then, you would guess and check try 49/60, 49/70, and go up by 10s or 5s. You will then realize that 49÷75 equals 65.333. This rounds up to 65.
What is the perimeter, to the NEAREST INCH, of the kite?
Answer:
18 units
Step-by-step explanation:
a+a=6
a=3
all the a lengths are the same
so the top two triangles have legs equal to a
we use a^2 + b^2 =c^2
a and b are the legs, c is the slant
9+9=18
c= sqrt. 18
we times that by 2 since there are two
so
8.485
then the bottom two triangles
a+b=7
3+b=7
b=4
a^2 + b^2 =c^2 (use again)
c=5
times by two
10
then add all the sides
10+8.485=18.485
