BAC ~ DEC
x = ___ units
Given:
[tex]\Delta BAC\sim \Delta DEC[/tex]
To find:
The value of x.
Solution:
We have,
[tex]\Delta BAC\sim \Delta DEC[/tex]
The corresponding parts of similar triangles are proportional.
[tex]\dfrac{AB}{ED}=\dfrac{AC}{EC}[/tex]
On substituting the values, we get
[tex]\dfrac{24}{56}=\dfrac{2x}{3x+5}[/tex]
[tex]\dfrac{3}{7}=\dfrac{2x}{3x+5}[/tex]
[tex]3(3x+5)=2x(7)[/tex]
[tex]9x+15=14x[/tex]
Subtract [tex]9x[/tex] from both sides.
[tex]15=14x-9x[/tex]
[tex]15=5x[/tex]
[tex]\dfrac{15}{5}=x[/tex]
[tex]3=x[/tex]
Therefore, the value of x is 3 units.

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.

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
Kerel wants to buy a Points card for his X-box live account. He can buy a 200-point
card for $10.00 or a 300-point card for $15.00. Which card is the better value?
Answer:
equal. i think
Step-by-step explanation:
well if 10$ 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

Give me a hand please! Triangle VZX is similar to RPQ where ZX corresponds to PQ. If VZ = 8 cm, ZX = 6.4 cm, VX = 11.2 cm, and PQ = 5.12 cm, what is the measure of RQ?
A) 4.096 cm
B) 10 cm
C) 8.96 cm
D) 6.4 cm
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

Don’t know what the answer is, help
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
The American Water Works Association reports that the per capita water use in a single-family home is 76 gallons per day. Legacy Ranch is a relatively new housing development. The builders installed more efficient water fixtures, such as low-flush toilets, and subsequently conducted a survey of the residences. Twenty-seven owners responded, and the sample mean water use per day was 71 gallons with a standard deviation of 9.5 gallons per day. At the 0.01 level of significance, is that enough evidence to conclude that residents of Legacy Ranch use less water on average
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.

Joann decides to paint one wall in her room with blackboard paint. The wall has the dimensions shown. A can of paint covers 25 square feet. How many cans of blackboard paint does Joann need for the wall.
*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.

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

The mean of this data is 31.17. [Answer]Use the net to find the surface area of the regular pyramid.
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:
40

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
