Write an equivalent expression to
3² x 15 x 54
Equivalent Expression: 9x + 15x = 54
Step-by-step explanation:
First, yo would do 3^2 which is 3 times 3 equals 9.
So, it would be 9x + 15x = 54
Then, you combine like terms, 9x + 15x
So 9+15= 24x
Last, would be 54 = 24x
divide by 24 onto both sides and then x will be by itself and then it will give you an answer.

Plssss help! Find the perimeter of each polygon. Assume that lines which appear to be tangent.
Answer:
11) 75.2
12) 44.2
Step-by-step explanation:
angles formed by intersecting lines tangent to a circle are the same length.
11)
Perimeter = 2(5) + 2(12) + 2(11.4) + 2(9.2) = 75.2
12)
Perimeter = 2(4) + 2(8) + 2(5.3) + 2(4.8) = 44.2
Write a function rule for "The output is 12 more than four times the input." Use x for the independent variable and y for the dependent variable. y=
Answer:
f(y) = 12 + 4x
Step-by-step explanation:
Output is 12 more than 4 timea the input
The dependent variable = y
The dependent variable = x
The input is the independent variable, x
Output is the dependent variable, y
Output = 12 + (4 * input)
Hence, the function rule can be written has :
f(y) = 12 + 4x

Step-by-step explanation:
Hello There!
The first step in solving this problem is to find the formula for volume of a cylinder
To find the volume of a cylinder we use this formula
[tex]V=\pi r^2h[/tex]
Where r = radius and h = hypotenuse
we are given the height and the diameter
To convert the diameter to radius we divide the diameter by 2
5/2=2.5
so the radius is 2.5
now we plug in the values
[tex]V=\pi 2.5^28\\2.5^2=6.25\\6.25\pi =19.63495408\\19.63495408*8=157.0796327[/tex]
So the volume of the cylinder is 157.0796327
now we just round to the nearest hundredth and get that the volume of the cylinder is 157.08

Answer:
[tex]\sqrt{0.5}[/tex]
Step-by-step explanation:
cosx=adj/hyp
adj= [tex]\sqrt{2}[/tex]/2
hyp= r
cos(45)= ([tex]\sqrt{2}[/tex]/2)/r
[tex]\sqrt{2}[/tex]/2 = ([tex]\sqrt{2}[/tex]/2)/r
multiply both sides by r
([tex]\sqrt{2}[/tex]/2)r = [tex]\sqrt{2}[/tex]/2
divide both sides by [tex]\sqrt{2}[/tex]/2
r = 1
pythagorean theorem: [tex]a^{2}[/tex] + [tex]b^{2}[/tex] = [tex]c^{2}[/tex]
a = [tex]\sqrt{2}[/tex]/2
b = y
c = r = 1
[tex](\sqrt{2}/2)^{2}[/tex] + [tex]y^{2}[/tex] = [tex]1^{2}[/tex]
[tex](\sqrt{2}/2)^{2}[/tex] = 2/4 = 0.5
0.5 + [tex]y^{2}[/tex] = 1
subtract 0.5 from 1
[tex]y^{2}[/tex] = 0.5
[tex]\sqrt{y^{2}}[/tex] = [tex]\sqrt{0.5}[/tex]
y = [tex]\sqrt{0.5}[/tex]

A cyclist rides her bike at a rate of 10 meters per second. What is this rate in kilometers per hour? How many kilometers will the cyclist travel in 4 hours? Do not round your answers.
Answer:
This rate in kilometers per hour is: 36 kilometers per hour. Also, the cyclist will travel 144 km in 4 hours.
Step-by-step explanation:
In order to find the rate in kilometers per hour, you have to consider that 1 meter per second is equal to 3.6 kilometers per hour and you can use a rule of three with this information:
1 meter per second → 3.6 kilometers per hour
10 meters per second → x
x=(10*3.6)/1=36 kilometers per hour
Now, you can use the formula to calculate speed and solve for the distance:
speed=distance/time
36=distance/4
distance=36*4
distance=144 km
According to this, the answer is that this rate in kilometers per hour is: 36 kilometers per hour. Also, the cyclist will travel 144 km in 4 hours.
What must be true about segment MN?
Answer:
The true properties of segment MN are;
1) MN is parallel to CB
2) MN = 2
Step-by-step explanation:
From the figure, we have;
The length of segment AN = 1
The length of segment NC = 2 = 2 × The length of segment AN
The length of segment AM = 1.8
The length of segment MB = 3.6 = 2 × The length of segment AM
The length of segment AC = 1 + 2 = 3
The length of segment AB = 1.8 + 3.6 = 5.4
Therefore, the length of transversal segments AC and AB are proportionally cut by the two lines, MN and CB
By the triangle proportionality theorem, two transversals are proportionally divided when they are crossed by two or more parallel lines
1) Therefore, lines MN and CB are parallel lines
Whereby we have that MN CB, we get;
ΔAMN ~ ΔABC
Therefore;
AN/AC = MN/CB
Plugging in the values, we get;
1/3 = MN/6
NM = 6 × 1/3 = 2
2) MN = 2
The length of segment CB = 6
Therefore, what must about segment MN are;
MN is parallel to CB and MN = 2.
By applying properties of similar triangles we got that MN is equal to 2 units.
What are similar triangles ?Triangles whose shape are same are known as similar triangle .
In the given figure we can see that
in triangle ABC and AMN
AN=1
NC=2
So AC= AN+NC=1+2=3
AM=1.8
MB=3.6
So AB=AM+MB=5.4
[tex]\frac{AN}{NC}=\frac{1}{3} \\\\[/tex]
and
[tex]\frac{AM}{AB} =\frac{1.8}{5.4}=\frac{1}{3}[/tex]
And angle A is common in both triangles
Hence by SAS property triangle ABC and AMN are similar .
So
[tex]\frac{MN}{CB}=\frac{1}{3} \\\\\\\\\frac{MN}{6}=\frac{1}{3} \\\\\\\\MN=2[/tex]
By applying properties of similar triangles we got that MN is equal to 2 units.

Carran is building a fence around his rectangular yard. The fence will cover the front and the 2 sides of the yard. The
front of the yard is 4 feet more than twice the length of one side of the yard. The sides of the yard are the same length. If
the perimeter of the yard is 80 feet, what are the dimensions of the fence?
9514 1404 393
Answer:
sides: 12 feetfront: 28 feetStep-by-step explanation:
Let x represent the length of one side of the yard. Then the width of the yard is 2x+4, and the perimeter is ...
P = 2(L +W) . . . . . . . . . . formula for perimeter of a rectangle
80 = 2(x + (2x+4)) . . . . . with values from the problem filled in
40 = 3x +4 . . . . . . . . divide by 2, collect terms
36 = 3x . . . . . . . . . subtract 4
12 = x . . . . . . . . . divide by 3. This is the length of the side fence.
2x +4 = 2(12) +4 = 28
The fence is 12 feet on the sides and 28 feet on the front. (Its total length is 52 feet.)

Three cards are selected one after the other from a standard deck of 52 cards.
What is the probability that all three cards are spades if none of the first two cards is replaced?
Answer:
[tex]\frac{11}{850}[/tex]
Step-by-step explanation:
Let's see
The probability of the first card being a spade is 13/52 (as there's 13 spades in the deck.
The probability for the second card is 12/51 (because there's 12 spades left in 51 cards total).
The probability for the third is - you guessed it! - 11/50
so the total probability is:
[tex]\frac{13}{52} \cdot \frac{12}{51} \cdot \frac{11}{50} = \frac{1}{4} \cdot \frac{4}{17} \cdot \frac{11}{50} = \frac{1}{17} \cdot \frac{11}{50} = \frac{11}{850}[/tex]
A more generic solution:
Let's use the binomials to find the solution with combinations:
We need to pick 3 cards out of 13. This can be done in
[tex]\binom{13}{3} = \frac{13!}{3!\cdot10!}[/tex] ways.
And the total number of ways to pick 3 cards out of 52 is:
[tex]\binom{52}{3} = \frac{52!}{3!\cdot 49!}[/tex]
So the probability is:
[tex]\frac{ \binom{13}{3} }{ \binom{52}{3} } = \frac{ \frac{13!}{3!\cdot 10!} }{ \frac{52!}{3!\cdot 49!} } = \frac{ \frac{13!}{10!} }{ \frac{52!}{49!} } = \frac{13 \cdot 12 \cdot 11}{52 \cdot 51 \cdot 50}[/tex]

Josephine was asked to make a one-fiftieth scale model of the new water tower for her town. She constructed the model that is shown below. A water tower has a height of 2.25 feet and diameter of 1.25 feet. Not drawn to scale What is the height of the town's new water tower in feet? Round to the nearest whole number.
Answer:
11.25 feet
Step-by-step explanation:
The model is 1/5 or 0.2 smaller than the original water tower
0.2 x water tower height = 2.25
water tower height = 2.25 / 0.2 = 11.25

1) Which of the following lines has an undefined slope?
A. y = 6x - 2
B. y = 3
C. y = -4x + 7
D. x = -5
Answer:
D
Step-by-step explanation:
An undefined slope (or an infinitely large slope) is the slope of a vertical line! The x-coordinate never changes no matter what the y-coordinate is! There is no run!
it cannot be written in slope-intercept form,
--So we can rule out A and B, since they are in Slope Intercept Form--
but it can be written in the form: x=a , where a is a constant.
B is not in the form x=a so we can rule that out.
D is in the correct form!
