Answer:

x=29

∠C=93°

Step-by-step explanation:

180°-52°-35°=3(x+2)°

180°-87°=(3x)°+6°

93°=(3x)°+6°

(3x)°=87°

x=[tex]\frac{87}{3}[/tex]

x=29

∠C=3(x+2)°

=3(29+2)°

=3(31)°

=93°

Answer:

33,333 ft^3

Step-by-step explanation:

A pyramids volume can be defined by V=lwh/3. We know the base is 1000 ft^2, so we multiply that by an additional 100 for the height. We then have 100,000 ft^3. After that, we simply divide it by three, which is 33,333.3 repeating, and round it to 33,333 ft^3

Answer:

Yes, that is enough statistical evidence to suggest to conclude that residents of Legacy Ranch use less water on average

Step-by-step explanation:

The data given by the American Water Works Association are;

The per capita water use in a single-family home, μ = 76 gallons per day

The number of responders in the sample, n = 27

The sample mean water used by the sample, [tex]\overline x[/tex] = 71 gallons

The standard deviation, s = 9.5 gallons per day

The level of significance, α = 0.01

The test statistics is given as follows;

The null hypothesis, H₀; μ ≥ 76 gallons

The alternative hypothesis, Hₐ; μ < 76 gallons

[tex]t=\dfrac{\bar{x}-\mu }{\dfrac{s}{\sqrt{n}}}[/tex]

Therefore, we have;

[tex]t=\dfrac{71-76 }{\dfrac{9.5}{\sqrt{27}}} \approx -2.734817[/tex]

At n - 1 = 27 - 1 = 26 degrees of freedom, the critical-t = 2.5

From the test statistic, of t ≈ -2.734817, the p-value < 0.01, and from a graphing calculator, the p-value is given as Prob = 0.005544418

Therefore, given that the p-value is less the significant level, and less than 0.01, is therefore statistically significant, and therefore, there is sufficient statistical evidence against the null hypothesis, therefore we reject the null hypothesis, and there is enough statistical evidence to suggest to conclude that residents of Legacy Ranch use less water on average.

Answer:

The variable is a nominal categorical variable

Step-by-step explanation:

As the 3 options are available and the survey taker is required to select from these options, this indicates that the variable is of categorical nature, where only a fixed number of options are available. As the order is not important thus the variable is a nominal categorical variable.

Answer: i think its alternate interior

Step-by-step explanation:

Mean= Sumof all the numbers/ number of data

So,

23+37+11+58+13+45=187

Now...

187/6=31.166666667 Answer

hope it helps....

What is the mean of this data: 23, 37, 11, 58, 13, 45.

To find the mean of this data, first of all we should add up all the given numbers and then divide by how many numbers there are.

So, [tex] \bf Mean \: = \frac{23 \: + \: 37 \: + \: 11 \: + \: 58 \: + \: 13 \: + \: 45}{6} [/tex]

[tex] \bf Mean \: = \frac{187}{6} [/tex]

[tex] \bf Mean \: = \: 31.17 [/tex]

Answer:

the percent of her comic books did Skylar give away is 20%

Step-by-step explanation:

Given that

Skylar has a collection of 60 comic books

She gave away some of her books

And she left by 48 books

we need to find out the percent of the skylar give away books

= (60 - 48) ÷ 60

= 12 books ÷ 60 books

= 20%

Hence, the percent of her comic books did Skylar give away is 20%

Answer:

Answer:

C: 8.96

Step-by-step explanation:

We know taht ZX is similar to PQ. We can now set up the ratio of 6.4: 5.12

This ratio gives us .8:1

Multiply VX by the ratio to find its corresponding similar side of RQ

(11.2) * .8 = 8.96

Answer:

40 in²

Step-by-step explanation:

There are four triangles for each side of the pyramid, and the height is three inches. The area of a triangle is base times height divided by 2, so each triangle is 6 in².

4(base) x 3(height) ÷ 2 = 6

Multiply 6 by 4 because there are four triangles, which is 24.

Once you have that, the only surface left is the bottom of the pyramid. You can find this by multiplying 4 by 4, since it's a square.

4 x 4 = 16

If you add 16 and 24 together, that's your answer.

answer BD is 108

Step-by-step explanation:

60^2+x^2=85^2

3600+x^2=7225

×^2=7225-3600

×^2=3625

Sq root both sides

x= 60

60+48=108

BD=108

Answer:4

Step-by-step explanation:

Answer:

126

AS:

If these cubes are to to be placed so that their respective faces are parallel

or perpendicular, as the case may be, to the respective orientations of the

dimensions of the box, without tilting any cubes in any directions,

then choice B) can be justified. This leaves spaces (some volume) in the box

not filled by the cubes.

How many whole number of edges of the cubes fit into 4 cm?  

4 / 3 √ 2   must be rounded down to 3.

How many whole number of edges of the cubes fit into 8 cm?  

8 / 3 √ 2   must be rounded down to 6.

How many whole number of edges of the cubes fit into 10 cm?  

10 / 3 √ 2   must be rounded down to 7.

Then (3)(6)(7) = 126

Answer:

equal. i think

Step-by-step explanation:

well if 10$ is worth 200 and 15 is worth 300 for me its adding half of the orginal number (200) and get 100 so 200+100=300

Both the cards are having the same value

What is an Equation?

Equations are mathematical statements with two algebraic expressions flanking the equals (=) sign on either side.

It demonstrates the equality of the relationship between the expressions printed on the left and right sides.

Coefficients, variables, operators, constants, terms, expressions, and the equal to sign are some of the components of an equation. The "=" sign and terms on both sides must always be present when writing an equation.

Given data ,

Let the first card be = A

Let the second card be = B

Now ,

The value of first card = $ 10.00

The value of second card = $ 20.00

And ,

The total value for 200 point cards = value of first card

The total value for 300 point cards = value of second card

So , the equation will be

200 = 10 A   be equation (1)

300 = 15 B   be equation (2)

Divide equation (1) by 10 on both sides , we get

A = 20

Divide equation (2) by 15 on both sides , we get

B = 20

Therefore , A = B

Hence , Both the cards are having the same value

yung 70

Step-by-step explanation:

i hope its help

carry on learning

Answer:

A

Step-by-step explanation:

143.6° and x are adjacent angles and sum to 180° , then

x + 143.6° = 180° ( subtract 143.6° from both sides )

x = 36.4° → A

Answer:

B.

Step-by-step explanation:

So, lets remember a few things first.

#1: The formula for finding the answer is A^2+B^2=C^2

#2: A is the opposite side, B is the adjacent side, and C is the hypotenouse side.

Now lets plug in what we already know, and see if we canf igure out the annswer:

A^2+12^2=13^2

Now I am going to stop us here. This is your equation that will find the answer. In your question, they use x^2, A^2 is a variable you can use instead. But looking at this, answer B and my equation I wrote above are exactly the same.

If you want, here is how I further solved it, this might give you a better grasp on what to do for future problems:

Ok, not  too bad, the A is the unkown value, which is the opposite side.

Now, how do we figure this out? Well, we just need to sovle for A.

To do this, lets clean up our equation by first sqauring all the values(except for the unkown):

A^2+144=169

Ok, that looks better, now lets just subtract the adjeacent side(b), which is 144, from the hypotenouse side(c), which is 169.

This will now look like:

A^2=25(169-144=25)

Ok, just one more step to go. Just square root both sides of the equation, this way, we will get ride of the ^2 on A(opposite side), and get A alone.

([tex]\sqrt{A^2}=A[/tex])=([tex]\sqrt{25}=5[/tex])

A=5

This is your answer.

*see attachment for the diagram of the wall

Answer:

6 cans

Step-by-step explanation:

First, let's calculate the area of the wall to be painted = area of a rectangle

Area of the rectangle = length*width

From the diagram,

Length = 13 ft

Width = 10 ft

Area = 13*10 = 130 ft²

Given that 1 can of paint covers 25 ft²,

Number of can of paints that will cover 130 ft² = 130/25 = 5.2

This means we will need more than 5 cans. So Joan will need to get roughly 6 cams of blackboard paint.
