What is the measure of angle PQR?
Answer:
40
Step-by-step explanation:
It tells you what Q, R is for the opening. That means that it is 40
The measure of angle PQR is 70 degrees
We have a right triangle - r is 90 degrees
based on geometric rules: angle RPQ = 20
40 : 2
90 + 20 = 110
110 + x = 180
What is the perimeter of the triangle?
The perimeter of the triangle is 180 degrees
The triangle has 180 degrees.
This means that 180 - 110 =70 degrees.
The measure of angle PQR is 70 degrees.

Write the equation in standard form, then identify center and radius of circle.
Answer:
Step-by-step explanation:
Given
x^2 + y^2 - 16y - 36 = 0
x^2 + y^2 - 16y = 36
x^2 + y^2 - 16y + (16/2)^2 = 36 + 8^2
x^2 + (y - 8)^2 = 64 + 36
x^2 + (y - 8)^2 = 100
The center is at (0,8) and the radius is 10

A circle has a circumference of 113.04113.04113, point, 04 units.
What is the diameter of the circle?
Answer:
around 36 is the diameter
Step-by-step explanation:
C=2Pir or pi*d
113.04=pi*d
113.04/pi=d
d≈36
give me brainliest[tex]≈[/tex]
36 units is the diameter of the circle.
What is Perimeter?The perimeter of a two-dimensional form is the space surrounding it. It represents the total length of the shape's sides. The units used to measure the sides of the form, such as meters, centimeters, inches, or feet, determine the units used to measure the perimeter.
We can use the formula for the circumference of a circle, C = πd,
where C is the circumference and d is the diameter.
Substituting the given value, we have:
113.04 = πd
To solve for d, we can divide both sides by π:
d = 113.04/π
Using a calculator to evaluate this expression, we get:
d ≈ 36
Therefore, the diameter of the circle is approximately 36 units.

Answer:
SA = 376.8 in²
Step-by-step explanation:
area of top:

50.24 x 2 = 100.48 in² (for both ends)
area of side:
circumference = 2 x 4 x π = 25.12 in

Step-by-step explanation:
Please help photos for my math
Answer:
1. Surface Area = 122 Volume = 84
2. Surface Area = 1632 Volume = 2880
3. Surface area = 168 Volume = 144
4. Volume = 1350[tex]\pi[/tex]
Step-by-step explanation:
1. This is a rectangular prism. To find the surface area it is the same thing. Find the area of all sides and add them together. Because this is a rectangular prism most of the sides are equal so we will only need to find the area of three sides. To find the area of the right side, just do 4*3=12. That would be the same for the opposite side. Then to find the front side, do 7*4= 28. That would also be the same for the opposite side. Then to find the top side, do 7*3= 21. That is the same for the bottom side. Add them all together and you will get your answer. 28+28+21+21+12+12 = 122.
To find the volume of a rectangular prism the formula is V = l*w*h.
Plug in: V = 7*3*4 and then you will get 84.
2. This is a triangular prism. First find the area of the the triangular surface by multiplying the base x height and dividing by 2. (16*12)/2 = 96. That is the same for the opposite side. Then find the area of the bottom rectangular surface. 12*30 = 360. Then find the area of the back rectangular surface. 16*30 = 480. Then find the area of the final base rectangle. 30*20 = 600. Add them together and you will get 1632. Basically, find the area of all sides and then add them together.
To find volume the formula is, V = (1/2)a*c*h
Fill that in: V = (1/2)16*12*30 and then you will get 2880.
3. This is a trapezoidal prism. To find the surface area you would find the area of all sides then add them together. To find the are of a trapezoid, the formula is: A = [tex]\frac{a+b}{2}[/tex]h
Fill that in: A = [tex]\frac{4+12}{2}[/tex](6) and then you will get 48.
That is the same for the opposite side. Then you need to find the area of the rectangular side of the trapezoidal prism. 3*4= 12. This is also the same as the opposite side. The bottom side is 12*3= 36. The top side is 3*4= 12.
Add all of them together and you get 168.
1/2(4+12)*6
To find volume, V = [tex]\frac{1}{2}[/tex]h(b₁+b₂)h.
Fill in: V = [tex]\frac{1}{2}[/tex]6(12+4)3 and then you will get 144.
4. This is a cylinder. The formula to find the volume is A=[tex]\pi[/tex]r²h. Because you are leaving the answer in terms of pi, do not multiply pi into the equation.
So you would do r²h. 15² = 225. 225*6= 1350. So your answer would be 1350[tex]\pi[/tex].

Genies is making cookies. She needs 1 2/3 cups of flour for one batch, but she wants to make 2 1/3 batches. Write an equation that can be used to find how many cups of flour genies will need
Equation: (1 2/3)(2 1/3) = x
Answer: 3 8/9 cups
Step-by-step explanation:
x represents the amount of flour she will need in cups.
To solve, convert the mixed numbers to improper fractions and multiply...
1 2/3 becomes 5/3
2 1/3 becomes 7/3
Now we have
(5/3)(7/3) = x
35/9 = x
35/9 is 3 8/9 as a mixed number

Seventy million pounds of trout are grown in the U.S. every year. Farm-raised trout contain an average of 32 grams of fat per pound, with a standard deviation of 7.5 grams of fat per pound. A random sample of 34 farm-raised trout is selected. The mean fat content for the sample is 30.5 grams per pound. Find the probability of observing a sample mean of 30.5 grams of fat per pound or less in a random sample of 34 farm-raised trout.
Answer:
0.121 = 12.1% probability of observing a sample mean of 30.5 grams of fat per pound or less in a random sample of 34 farm-raised trout.
Step-by-step explanation:
To solve this question, we need to understand the normal probability distribution and the central limit theorem.
Normal Probability Distribution:
Problems of normal distributions can be solved using the z-score formula.
In a set with mean [tex]\mu[/tex] and standard deviation [tex]\sigma[/tex], the z-score of a measure X is given by:
[tex]Z = \frac{X - \mu}{\sigma}[/tex]
The Z-score measures how many standard deviations the measure is from the mean. After finding the Z-score, we look at the z-score table and find the p-value associated with this z-score. This p-value is the probability that the value of the measure is smaller than X, that is, the percentile of X. Subtracting 1 by the p-value, we get the probability that the value of the measure is greater than X.
Central Limit Theorem
The Central Limit Theorem estabilishes that, for a normally distributed random variable X, with mean [tex]\mu[/tex] and standard deviation [tex]\sigma[/tex], the sampling distribution of the sample means with size n can be approximated to a normal distribution with mean [tex]\mu[/tex] and standard deviation [tex]s = \frac{\sigma}{\sqrt{n}}[/tex].
For a skewed variable, the Central Limit Theorem can also be applied, as long as n is at least 30.
Farm-raised trout contain an average of 32 grams of fat per pound, with a standard deviation of 7.5 grams of fat per pound.
This means that [tex]\mu = 32, \sigma = 7.5[/tex]
Sample of 34:
This means that [tex]n = 34, s = \frac{7.5}{\sqrt{34}} = 1.2862[/tex]
Find the probability of observing a sample mean of 30.5 grams of fat per pound or less in a random sample of 34 farm-raised trout.
This is the pvalue of Z when X = 30.5. So
[tex]Z = \frac{X - \mu}{\sigma}[/tex]
By the Central Limit Theorem
[tex]Z = \frac{X - \mu}{s}[/tex]
[tex]Z = \frac{30.5 - 32}{1.2862}[/tex]
[tex]Z = -1.17[/tex]
[tex]Z = -1.17[/tex] has a pvalue of 0.121
0.121 = 12.1% probability of observing a sample mean of 30.5 grams of fat per pound or less in a random sample of 34 farm-raised trout.

Let tan theta= 5/12, where sin theta> 0.
Find the exact value of sec theta
Answer:
5/13
Step-by-step explanation:
1. We are given tan(x)=5/12 .....(2)
2. On comparing the quantities we get that p=5 and b=12
3. We require the value of hypotenuse(h),
for this we apply the Pythagoreum theorum: p^2+b^2=h^2
⇒h^2=5^2+12^2
⇒h^2=25+144
⇒h^2=169
⇒ h=√169
⇒ h=13
Sin=p/h
p=5
h=13
Sin=5/13

3.

Raymond bought wrapping paper that cost
$0.04 per square inch. How much did it cost to
wrap this box.
Answer: $46.08
Step-by-step explanation:
Find the surface Area of the box
the bases are 12*12= 144 times 2 bases 144*2= 288
The area of each side is 12*18=216 times 4 sides 216*4=864
add the totals together to find the total surface area 288+864=1152
total surface area is 1152 inches. Multiply by the cost per square inch
1152*.04= 46.08
