What’s the answers and now would I work this out ?
Answer:
15 cm²
Step-by-step explanation:
To find the volume of a prism you multiply the area of the end face (pentagon in this example) by the length (9 cm). Here you would reverse that and divide the volume by the length to find the area. 135/9 is 15 so the area of the pentagon is 15 cm².
In equation form would be:
V=A×L [V=volume A=area L=length]
So if you do inverse operations you would divide the volume by the length to get the area.
V/L=A
Find the measures of each numbered angles
Answer:
∠ 1 = 109° , ∠ 2 = 29° , ∠ 3 = 71°
Step-by-step explanation:
The sum of the 3 angles in a triangle = 180° , then
∠ 1 + 35° + 36° = 180°
∠ 1 + 71° = 180° ( subtract 71° from both sides )
∠ 1 = 109°
-------------------
∠ RVU and ∠ 1 are adjacent angles on a straight line and sum to 180° , then
∠ RVU + ∠ 1 = 180°
∠ RVU + 109° = 180° ( subtract 109° from both sides )
∠ RVU = 71°
In Δ RVU
∠ 2 + 80° + 71° = 180° ( sum of angles in triangle )
∠ 2 + 151° = 180° ( subtract 151° from both sides )
∠ 2 = 29°
-------------------------
∠ 3 and ∠ RVU are vertically opposite angles and are congruent , then
∠ 3 = 71°
Δ UVT has: ∠V₁ = 180⁰ - ∠TUV - ∠VTU = 180⁰ - 35⁰ - 36⁰ = 109⁰
We have: ∠RVU = ∠V₃ = 180⁰ - ∠V₁ = 180⁰ - 109⁰ = 71⁰
ΔRVU has: ∠U₂ = 180⁰ - ∠URV - ∠ RVU = 180⁰ - 80⁰ - 71⁰ = 29⁰
Answer:
∠V₁ = 109⁰∠U₂ = 29⁰∠V₃ = 71⁰Ok done. Thank to me :>

In right triangle ABC below, CD is the altitude to hypotenuse AB. If CD=6 and the ratio of AD to AB is 1:5, determine and state the length of BD.
Step-by-step explanation:
the altitude makes a right angle at hypotenuse
cd^2+ ad^2 = ac^2
36+ (h/5)^2 = ac^2
ad/ab = 1/5; ad/h = 1/5; ad=h/5
similarly
bd^2+cd^2 = bc^2
(4/5)^2+ 36 = bc^2
ac^2+bc^2 = ab^2
36+h^2/25+ 16/25h^2+36 = h^2
h= 15
bd/ab = 4/5
bd= .8*15=12

Answer:

Scores on an exam follow an approximately normal distribution with a mean of 76. 4 and a standard deviation of 6. 1 points. What percent of students scored above 75 points?.
Using the normal distribution, it is found that 59.09% of students scored above 75 points.
Normal Probability DistributionIn a normal distribution 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]
It 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, which is the percentile of X.In this problem:
The mean is [tex]\mu = 76.4[/tex].The standard deviation is [tex]\sigma = 6.1[/tex].The proportion of students who scored above 75 points is 1 subtracted by the p-value of Z when X = 75, hence:
[tex]Z = \frac{X - \mu}{\sigma}[/tex]
[tex]Z = \frac{75 - 76.4}{6.1}[/tex]
[tex]Z = -0.23[/tex]
[tex]Z = -0.23[/tex] has a p-value of 0.4091.
1 - 0.4091 = 0.5909
0.5909 = 59.09% of students scored above 75 points.

The sum of the measures of three adjacent angles is 150∘. The measures of the angles are in the ratio of 1:2:3. What is the measure, in degrees, of the largest angle?
Answer:
75°
Step-by-step explanation:
1:2:3
so there are a total of 6 parts. Then, each part would be:
=) 150÷6= 25
The largest angle is 3 parts. so, if 1 part is 25, 3 parts is 25×3= 75
The largest angle is is 75°

The graph is a line.
The graph intersects
the x-axis.
The input x-1 has
many outputs.
The graph is a
vertical line.
Answer:
The input x = 1 has many outputs.
The graph is a vertical line.
Step-by-step explanation:
Hi there!
A function is defined as a relation that only gives one output for every given input. For every x-value, there is only one y-value.
Because the x-value of 1 gives us an infinite number of y-values, this is therefore not a function.
More generally, no vertical line is a function for this reason.

You already have the answer. It is "One type of proof is a two-column proof. It contains statements and reasons in columns.

Nora rings up an item that costs $86.25. After sales tax, the total is $91.08. What is the sales tax percentage?
Write your answer as a decimal using a percent sign (%). For example, 0.5% or 12.7%
Answer:
The sales tax is equal to 5.6%
Step-by-step explanation:
To solve first we have to subtract the item's cost before sales tax from the total due. 91.08 - 86.25 = 4.83.
Next we take the amount we payed as tax and divide it by the pre-tax price. 4.83/86.25 = 0.056
Lastly we take 0.056 and convert it to a percentage. This can be accomplished by moving the decimal sign to 2 times to the left or multiplying the tax rate by 100.
The sales tax percentage is equal to 5.6%
Hope this helps you out :)
