The perimeter of a rectangle is 92 cm. If the length is 22 cm, how wide is the rectangle?
A) First write an equation you can use to answer this question. Use w as your variable in the equation.
Answer:
W = 24cm
Step-by-step explanation:
p of a rectangle = 92
L = 22cm and W = ?
p = 2(L+W)
92 = 2(22+W)
92 = 44 + 2W
2W = 92 - 44
2W = 48
W = 48/2
W = 24cm
what is the equivalent of 3/8
Answer:
6/16 is equivalent to 3/8 because after dividing the numerator (6) and denominator (16) we get 3/8.
If two functions are inverses of each other, which 2 statements are true?
A The graph of an inverse of a function is a reflection of the function across the line y=x. B f(g(x)) = x and g(f(x)) = x
C The graph of an inverse of a function is a reflection of the function across the line y=0. D f(g(x)) =1 and g(f(x)) = 1
Answer:
A and B
Step-by-step explanation:
To be inverses, the inverse composite functions must equal x, since the input and output must be equal as how much you used as your input, which is x. B proves that. Also, the graph must reflect over y = x, which is the line that runs through the origin

DONT SOLVE
Answer:
I won't solve it, because you asked me to.
Step-by-step explanation:
The first question we should ask ourselves is "what are we looking to solve?"
We are looking for some sort of value that satisfies that equation. We'll call it x
Reading from left to right:
The sum of twice a number and 13 is 75
+ 2 x 13 = 75
2x + 13 = 75
Rewrite 0.580 80 repeating decimal
Step-by-step explanation:
first off, we'll move the non-repeating part in the decimal to the left-side, by doing a division by a power of 10.
then we'll equate the value to some variable, and move the repeating part over to the left as well.
anyhow, the idea being, we can just use that variable, say "x" for the repeating bit, let's proceed,
\begin{gathered}\bf 0.580\overline{80}\implies \boxed{\cfrac{5.80\overline{80}}{10}}\qquad \textit{now, let's say }x= 5.80\overline{80}\\\\ -------------------------------\end{gathered}
0.580

now, let’s say x=5.80

−−−−−−−−−−−−−−−−−−−−−−−−−−−−−−−
\begin{gathered}\bf thus\qquad \begin{array}{llll} 100\cdot x&=&580.80\overline{80}\\ &&575+5.80\overline{80}\\ &&575+x \end{array}\qquad \implies 100x=575+x \\\\\\ 99x=575\implies x=\cfrac{575}{99}\qquad therefore\qquad \boxed{\cfrac{5.80\overline{80}}{10}}\implies \cfrac{\quad \frac{575}{99}\quad }{10} \\\\\\ \cfrac{\quad \frac{575}{99}\quad }{\frac{10}{1}}\implies \cfrac{575}{99}\cdot \cfrac{1}{10}\implies \cfrac{575}{990}\implies \stackrel{simplified}{\cfrac{115}{198}}\end{gathered}
thus
100⋅x

h(t) = 3t2 + 4t
g(t) = t - 1
Find h(g(t))
3t2 - 2t - 1
4+3 - 12t + 1
3t2 + 4t - 1
3t2 - 4t - 1
Answer:
first we need to substitute g(t) value in h(t) value and then evaluate the expression as follows :
h(g(t))=3(t-1)²+4(t-1).
by solving
h(g(t))=3(t²+1-2t)+4t-4
h(g(t))=3t²-2t-1 will.be the final answer

If there are 95 male students for every 100 female students at Northwest Vista College, to the nearest
0.1%, what percent of the students are female?
Answer:
51.3%
Step-by-step explanation:
You must divide 100 by 195. In order to find the equivalent ratio you must multiply the number you are dividing by, by 100. So it will become 100/195.

In the diagram, what is mAngleVSR?
2 lines intersect. A horizontal line has points R, S, U and intersects a line with points V, S, T at point S. Angle V S U is 100 degrees.
mVSR =
The measure of m∠VSR if the horizontal line has points R, S, U and intersects a line with points V, S, T at point S is 80degrees
The point where two lines intersect is known as an angle.
Find the diagram to the question attached below.
From the diagram shown, we can see that the angle m∠VSR and m∠VSU lie on the line RSU which shows that the sum of these angles is supplementary. Hence:
m∠VSU + ∠VSR = 180
Given that m∠VSU = 100 degrees
∠VSR = 180 - ∠VSU
∠VSR = 180 - 100
∠VSR = 80degrees
Hence the measure of m∠VSR if the horizontal line has points R, S, U and intersects a line with points V, S, T at point S is 80degrees

A business uses straight-line depreciation to determine the value y of a piece of machinery over a 10-year period. Suppose the original value (when t=0) is equal to $34,000 and its value is reduced by $3400 each year. Write the linear equation that models the value y of this machinery at the end of year t.
The linear equation that models the value y of this machinery at the end of year t is y = $34,000 - $3,400t
A linear equation is an algebraic equation in the form :
y = mx + b
where y = intercept
m = slope
x and y are variables
Depreciation is used in expensing the cost of the asset
The value of the asset reduces by $3400 every year
The equation is :
y = $34,000 - $3,400t
At the end of one year, y = $34,000 - $3,400(1) = $30,600
At the end of two years, y = $34,000 - $3,400(2) = $27,200
At the end of ten years, y = $34,000 - $3,400(10) = 0

Given the complex number z=6(cos120+isin120), find z3
Answer:
B
Step-by-step explanation:
We are given the complex number:
[tex]\displaystyle z = 6(\cos 120^\circ + i\sin 120^\circ)[/tex]
And we want to find z³.
Recall that:
[tex]\displaystyle z^n = r^n(\cos(n\theta) + i\sin (n\theta))[/tex]
In this case, n = 3. Hence:
[tex]\displaystyle z ^3 = (6)^3 (\cos (3(120^\circ)) + i\sin (3(120^\circ))[/tex]
Simplify:
[tex]\displaystyle z^3 = 216(\cos 360^\circ + i\sin 360^\circ)[/tex]
Evaluate:
[tex]\displaysyle z^3 = 216( 1 + i(0)) = 216[/tex]
In conclusion, our answer is B.
