Answer:
15
Step-by-step explanation:
cancel out from the sides till you have 1 number in the middle but in this case we have 2 numbers.
in a case like that you add both numbers and divide by 2 to get your answer
so 16+14÷2= 15

Answer:
104 degrees
Step-by-step explanation:
The whole shape will come to 360 degrees, so if you add 126 degrees and 26 degrees it will come to 152 degrees. You then subtract 152 degrees fro. 360 degrees, this will give you 208 degrees. Then you divide 208 degrees by 2 that results in 104 degrees. So 104 degrees is the answer.

Answer:
options C -x^2/3z
Step-by-step explanation:
this is the correct answer after we cancelled them
Answer:
C
Step-by-step explanation:
This requires you to know the law of quotient for exponents. For this I recommend separating everything with the same variable into its own fraction to make it easier so you have (-2x^4/6x^2), (y^2/y^2), (z/z^2). Then to simplify you divide the coefficients and signs like normal but for the exponents, you subtract the exponent of the numerator from the denominator. This gives
(-x^2 / 3), (1), and ( 1/z), which you can multiple together to get c.
Hope this helps. Ask if you need me to clarify something.

was 6 times the number of plates. He made
90 bowls during the week. Write an equation that
could be used to find the number of plates p that
the potter made.
Answer:
Step-by-step explanation:
the number of bowls was 6 times the number of plates.
b = 6p
He made 90 bowls during the week.
90 = 6p
p = 15
He made 15 plates during the week.
What are the ordered pairs of the
solutions for this system of equations?
f(x)=x^2 – 2x + 3; f(x) = -2x + 19
(4, [?]); ([ ], [])
Answer:
(4, 11) is one ordered pair and (-4, 27) is the other ordered pair
Step-by-step explanation:
(1) f(x) = x^2 - 2x + 3 (2) f(x) = -2x + 19
-2x + 19 = x^2 - 2x + 3
x^2 - 16 = 0
(x - 4)(x + 4) = 0
x = 4 or x = -4 -2(4) + 19 = 11
-2(-4) + 19 = 27
So, when x = 4, y = 11 and when x = -4, y = 27
(4, 11) is one ordered pair and (-4, 27) is the other ordered pair

Market researchers were interested in the relationship between the number of pieces in a brick-building set and the
cost of a set. Information was collected from a survey and was used to obtain the regression equation ý = 0.08x +
1.20, where x represents the number of pieces in a set and is the predicted price (in dollars) of a set. Which
statement best describes the meaning of the y-intercept of the regression line?
Answer: c. When the number of pieces is 0, the predicted price is $1.20. This interpretation is not meaningful because a set cannot have 0 pieces
Step-by-step explanation:
The y-intercept in a regression equation shows the value of y when x is 0. For this scenario therefore, the y-intercept is the predicted price of a set when the number of pieces in the set is 0. As the y-intercept is 1.20, this means that when there are no pieces in the set, the predicted price is $1.20.
This however is not logical or meaningful because a set cannot have 0 pieces and if it did, it wouldn't make sense for somebody to pay $1.20 for it.
When the number of pieces is 0, the predicted price is $1.20.
This interpretation is not meaningful because a set cannot have 0 pieces.
We have given that,
Market researchers were interested in the relationship between the number of pieces in a brick-building set and the cost of a set.
What is the regression equation?
regression analysis is a set of statistical processes for estimating the relationships between a dependent variable and one or more independent variables.
The y-intercept in a regression equation shows the value of y when x is 0. For this scenario, therefore, the y-intercept is the predicted price of a set when the number of pieces in the set is 0.

So a slope of 1/4 means that for every 4 steps you take forward, you would go up 1.
With this, beginning at the point (6,3), lets take 4 steps back and go down 1. This is instead of going forward, as that value would be outside of your graph We would end up at (2,2). By using these two points, you can graph your line.

Cornelius is building a solar system model. He plans on making a circular ring around one of the planets out of wire. He wants to know how long he should make the wire to position around the planet. Select all the formulas that coulr be used to determine the length of the circular ring.
Answer:
[tex]C = 2\pi r[/tex]
[tex]C = \pi d[/tex]
Step-by-step explanation:
Given
A circular ring
Required
The length
Let
[tex]r \to[/tex] the radius of the ring
The length is calculated by calculating the circumference of the ring.
This is calculated using:
[tex]C = 2\pi r[/tex]
or
[tex]C = \pi d[/tex]
Where
[tex]d \to[/tex] diameter
and [tex]d = 2r[/tex]

[tex]V_2 = \frac{\pi}{4} [ \frac{(2r)^2h}{3}][/tex] or [tex]V_2 = \frac{1}{3}\pi r^2h[/tex]
Step-by-step explanation:
Given
[tex]Ratio = \frac{\pi}{4}[/tex]
See attachment for complete question
Required
Determine the volume of the cone
The volume of a square pyramid is:
[tex]V = \frac{a^2h}{3}[/tex]
Where
a = base dimension
From the attachment, the base dimension of the square pyramid is 2r.
So:
[tex]a = 2r[/tex]
The volume becomes;
[tex]V = \frac{(2r)^2h}{3}[/tex]
To calculate the volume of the cone, we simply multiply the given ratio and the volume of the prism.
So, we have:
[tex]V_2 = Ratio * V[/tex]
[tex]V_2 = \frac{\pi}{4} [ \frac{(2r)^2h}{3}][/tex]
[tex]V_2 = \frac{\pi}{4} * \frac{(2r)^2h}{3}[/tex]
Open bracket;
[tex]V_2 = \frac{\pi}{4} * \frac{4r^2h}{3}[/tex]
Cancel out 4
[tex]V_2 = \pi * \frac{r^2h}{3}[/tex]
The above can be written as:
[tex]V_2 = \frac{1}{3} * \pi r^2h[/tex]
[tex]V_2 = \frac{1}{3}\pi r^2h[/tex]
So, we have:
[tex]V_2 = \frac{\pi}{4} [ \frac{(2r)^2h}{3}][/tex]
or
[tex]V_2 = \frac{1}{3}\pi r^2h[/tex]
Michelle invested $10,000 in an account that earns 8.5% interest that is compounded monthly. Determine the amount of money in the account in 15 years
Given:
The principal value = $10,000
Rate of interest = 8.5% compounded monthly.
To find:
The amount of money in the account in 15 years.
Solution:
The formula for amount is:
[tex]A=P\left(1+\dfrac{r}{n}\right)^{nt}[/tex]
Where, P is principal, r is the rate of interest in decimal, n is the number of times interest compounded in an year, t is the number of years.
Number of months in an year is 12. So, n=12.
Substitute [tex]P=10000, r=0.085, n=12, t=15[/tex] in the above formula.
[tex]A=10000\left(1+\dfrac{0.085}{12}\right)^{12(15)}[/tex]
[tex]A=10000\left(\dfrac{12.085}{12}\right)^{180}[/tex]
[tex]A=35626.53335[/tex]
[tex]A\approx 35626.53[/tex]
Therefore, the amount of money in the account in 15 years is $35626.53.

Answer:
D. 30 Ft.
Step-by-step explanation:
Split the trapezoid into two shapes for an easier process .
The ideal split shall result in two shapes: A rectangle and a right triangle .
Rectangle Formula: L · W = A
Substitution: 6 · 4 = 24 Ft.
Right Triangle Formula: ( B · H ) ÷ 2 = A
Substitution: ( 3 · 4 ) ÷ 2 = 6 Ft.
Add the separate areas together to get the final result .
24 + 6 = 30 Ft.
