Answer:
x=6
Step-by-step explanation:
Simplifying
x + 15 = 21
Reorder the terms:
15 + x = 21
Solving
15 + x = 21
Solving for variable 'x'.
Move all terms containing x to the left, all other terms to the right.
Add '-15' to each side of the equation.
15 + -15 + x = 21 + -15
Combine like terms: 15 + -15 = 0
0 + x = 21 + -15
x = 21 + -15
Combine like terms: 21 + -15 = 6
x = 6
Simplifying
x = 6

1.2675 * 10^37 =
help pls its like 3am and for some reason my brain doesn't work :)
Answer:
the answer of the given equation is 1.2675E+37
Step-by-step explanation:
The computation is shown below:
Given that
= 1.2675 × 10^37
The above equation we need to solve
So,
= 1.2675 × 1E+37
= 1.2675E+37
So the answer after solving the equation is 1.2675E+37
The same would be considered and relevant
Hence, the answer of the given equation is 1.2675E+37

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
Skylar has a collection of 60 comic books. She gave away some of her comic books to her friend. After she gave them away, she had 48 still. What percent of her comic books did Skylar give away?
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%
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

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

You ask learners to select their course section number for your survey. For example, (1) 101, (2) 102, (3) 103. What type of variable is course section in this example?
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:
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:
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

Step-by-step explanation:
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.

2. What is the product of column B?
What is the product of column C?
Answer:
1. -5
2. -24
3. 0

Sum means addition.
Product means multiplication.
A negative times a negative will give you a positive.
Anything times zero is zero.
1. -2 + 5 + (-8) = -5
2. -1 * -4 * -6 = -24
3. 10 * 0 *-9 = 0

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

The equation of a circle is x2 + y2 - 12y + 20 = 0
What are the coordinates of the center and the length of the radius of the circle?
Answer:
Center: (0, 6); radius = 4
Step-by-step explanation:
x^2 + y^2 - 12y + 20 = 0
We must complete the square in y.
x^2 + y^2 - 12y = -20
x^2 + y^2 - 12y + 36 = -20 + 36
x^2 + (y - 6)^2 = 16
(x - 0)^2 + (y - 6)^2 = 4^2
Center: (0, 6); radius = 4
