Answer:
$36 (see below)
Step-by-step explanation:
First, you have to find how much they paid for one ticket.
If they paid $12 for 3, then they paid $4 for 1.
You could've also use a ratio:
$12 $x
-------- = --------
3 1
Cross multiply:
$12 (1) = $3x
$12 = $3x
$4 = x
So $4 for 1 ticket.
To find the cost of 9 tickets, just multiply the price by the number of tickets, which is:
$4 (9) = $36

What is the equation of the line
The school sells 240 cookies. ¼ of the cookies had chocolate chips, ½ of the remaining cookies had raisins, and the rest were peanut butter. How many cookies were peanut butter?
Answer:
90 peanut butter
Step-by-step explanation:
Total number of cookies [tex]=240[/tex]
Number of chocolate cookies [tex]=\frac{1}{4}(240)=60[/tex]
Therefore,
Number of remaining cookies [tex]=240-60=180[/tex]
Number of raisins [tex]=\frac{1}{2}(180)=90[/tex]
So,
Number of peanut butter [tex]=180-90=90[/tex]

In this diagram, circle A had a radius = 11.3 and BC = 13.3. BC is a tangent line, calculate the distance of CD.
Answer:
24.6 is the distance of CDConvert 27 ounces into grams.
Hint: 1 ounce=28.35 grams
Answer:
765.437 grams
Step-by-step explanation:
as 1 ounce =28.35g
so
27ounce=28.35×27
=765.437
Converting 27 ounces into grams is: 765.437grams.
Here, we have,
given that,
we have to Convert 27 ounces into grams.
we know that,
Since 1 ounce is equal to 28.35 grams.
so, we get,
1 ounce=28.35 grams
all we need to do is to multiply 27 by 28.35 grams.
i.e. 28.35×27 =765.437
The answer will be 765.437grams.
so, we get,
as 1 ounce =28.35g
so, 27ounce=28.35×27 =765.437g

Answer:
[tex]\frac{22}{30} = \frac{11}{15}[/tex]
and
[tex]\frac{176}{7} = 25 \frac{1}{7}[/tex]
Step-by-step explanation:
First make all the fractions into improper fractions
[tex]1\frac{5}{6} = \frac{11}{6} \\\\2\frac{1}{2} = \frac{5}{2} \\\\3\frac{1}{7} = \frac{22}{7}[/tex]
After doing that put them back into the problems
Problem 1)
[tex]1\frac{5}{6}[/tex] ÷ [tex]2\frac{1}{2}[/tex] , plug in the improper fractions
[tex]\frac{11}{6}[/tex] ÷ [tex]\frac{5}{2}[/tex]
to divide, you need to flip the second fraction and multiply
[tex]\frac{11}{6}[/tex]· [tex]\frac{2}{5}[/tex] = [tex]\frac{22}{30}[/tex]
then reduce
[tex]\frac{22}{30} = \frac{11}{15}[/tex]
Problem 2)
[tex]3\frac{1}{7}[/tex]÷ [tex]\frac{1}{8}\\[/tex]
Plug in improper fraction
[tex]\frac{22}{7}[/tex] ÷ [tex]\frac{1}{8}\\[/tex]
Then flip second fraction and multiply
[tex]\frac{22}{7}[/tex] · [tex]\frac{8}{1}[/tex]
Multiply
[tex]\frac{176}{7}[/tex]
Reduce, or make it a mixed number
[tex]\frac{176}{7} = 25 \frac{1}{7}[/tex]

Answer:
angle 2 = 133
angle 3 = 47
Step-by-step explanation:
angle 2 and angle 1 are supplementary, so they equal 180. 180- 47=133
angle 3 and angle 4 are supplementary, so they equal 180. 180- 133=47
7 + x/5 = - 4 x=___ help
Answer:
x = -55
Step-by-step explanation:
7 + x/5 = -4
Combine the constants.
x/5 = -11
Multiply both sides by 5 to simplify the denominator.
x = -55
Check.
7 + (-55)/5 = -4
7 + (-11) = -4
7 - 11 = -4
-4 = -4
Your answer is correct.
Hope this helps!
Answer:
[tex]7 + \frac{x}{5} = - 4 \\ \frac{x}{5} = - 4 - 7 \\ = - 11 \\ x = - 11 \times 5 \\ = - 55[/tex]
Given that cos θ = –12∕13 and θ is in quadrant III, find csc θ.
Question 20 options:
A)
–13∕5
B)
13∕5
C)
5∕13
D)
–5∕13
Answer:
A
Step-by-step explanation:
We are given:
[tex]\displaystyle \cos(\theta)=-\frac{12}{13},\,\theta\in\text{QIII}[/tex]
Since cosine is the ratio of the adjacent side over the hypotenuse, this means that the opposite side is (we can ignore negatives for now):
[tex]o=\sqrt{13^2-12^2}=\sqrt{25}=5[/tex]
So, the opposite side is 5, the adjacent side is 12, and the hypotenuse is 13.
And since θ is in QIII, sine/cosecant is negative, cosine/secant is negative, and tangent/cotangent is positive.
Cosecant is given by the hypotenuse over the opposite side. Thus:
[tex]\displaystyle \csc(\theta)=\frac{13}{5}[/tex]
Since θ is in QIII, cosecant must be negative:
[tex]\displaystyle \csc(\theta)=-\frac{13}{5}[/tex]
Our answer is A.
Answer:
A

write the slope intercept form of the equation with the given slope and y-intercept.
1. Slope= -10, y- intercept = -5 2. Slope= - 9/5, y- intercept = -4
3.Slope= -5/4, y- intercept = 5 4. Slope= 7, y- intercept = 5
Answer:
1. y = -10x - 5
2. [tex]y = \frac{9}{5}x - 4[/tex]
3. [tex]y = -\frac{5}{4}x + 5[/tex]
4. y = 7x + 5
Step-by-step explanation:
use y = mx + b
m = slope
b = y-intercept
1. Slope= -10, y- intercept = -5
y = -10x - 5
2. Slope= - 9/5, y- intercept = -4
[tex]y = \frac{9}{5}x - 4[/tex]
3. Slope= -5/4, y- intercept = 5
[tex]y = -\frac{5}{4}x + 5[/tex]
4. Slope= 7, y- intercept = 5
y = 7x + 5
38. A football pitch measuring 120m by
80m is surrounded by a running track
measuring 15m wide all round. Find
area covered by the running track
Answer:
Area of the running track = 6900 m²
Step-by-step explanation:
Length of a football pitch = 120 m
Width of the football pitch = 80 m
Area of the football pitch (Inner rectangle) = Length × Width
= 120 × 80
= 9600 m²
If a running track (width = 15 m) is built around the football pitch,
Length of the outer rectangle = 120 + 2×(15)
= 120 + 30
= 150 m
Width of the outer rectangle = 80 + 2×(15)
= 110 m
Area of the outer rectangle = 150 × 110
= 16500 m²
Therefore, area of the track around the football pitch = Outer rectangle - Inner rectangle
= 16500 - 9600
= 6900 m²
Area of the running track = 6900 m²

A rectangular cake pan is 13 inches by 9 inches by 2 inches. A round cake pan has a
diameter of 8 inches and a height of 2 inches. Which will hold more batter, one
rectangular pan or two round pans?
Answer:
The rectangular pan will hold more batter
Step-by-step explanation:
To find the volume of a rectangular prism, such as the first cake pan, you need to multiply all of the dimensions. The equation looks like this: "V = l * w * h" substituting the variables with the numbers would make it say "13 * 9 * 2" which would be 234 [tex]in^{3}[/tex]
To find the volume of a cylinder, the equation is "V=π[tex]r^{2}[/tex]h". The radius is half the diameter, so "r" would be 4, being half of 8. The substituted equation would read "π[tex]4^{2}[/tex]2", making the cylinder's volume roughly 100.53 [tex]in^{3}[/tex]
When you take those two numbers, you are able to see that 234 is bigger than 100.53, therefore making the rectangular pan larger.

Solve the system of linear equations by substitution. 3x-4y=12 x=-2y+4
Answer:
x=4, y=0. (4, 0).
Step-by-step explanation:
3x-4y=12
x=-2y+4
-----------
3(-2y+4)-4y=12
-6y+12-4y=12
-10y=12-12
-10y=0
y=0/-10=0
x=-2(0)+4=0+4=4
Answer:
Step-by-step explanation:
if x=-2y+4
3x-4y=12 becomes
3(-2y+4)-4y=12
-6y+12-4y=12
-10y+12=12
-10y=0
y=0
since x=-2y+4
x=-2(0)+4
x=4
so the solution is the point (4,0)

*Complete Question:
A and B are two similar cylindrical containers.
Surface area of container A: surface area of container B = 4:25
Warda fills container A with oil.
She then pours all the oil into container B.
Warda repeats this and stops when container B is full of oil.
Work out the number of times that Warda fills container A with oil.
Answer/Step-by-step explanation:
We are given that the ratio of surface area of cylinder A to cylinder B = 4:25
To find out the number of times Warda fills cylinder A with oil, we need to find the ratio of the volume of cylinder A to cylinder B.
✔️First, find the linear measurement using the ratio of their surface area by taking their square root:
4:25 = √4/√25 = 2/5
Linear measurement of A to B = 2:5
The ratio of their volume = the cube of the ratio of their linear measurement
Thus, the ratio of the volume of A to B = 2³:5³ = 8:125
For Cylinder B to be filled, it would require 125/8 = 15.625 of cylinder A filled with oil. That means Warda would have to fill Cylinder A with oil for approximately 15 times, then an extra fraction of cylinder A to completely fill cylinder B with oil.
