Find the value of x.
2x
80
27
60
X =
Answer:
x = 18
Step-by-step explanation:
The inner and outer triangles are similar, thus the ratios of corresponding sides are equal, that is
[tex]\frac{80}{80+2x}[/tex] = [tex]\frac{60}{60+27}[/tex] = [tex]\frac{60}{87}[/tex] ( cross- multiply )
60(80 + 2x) = 6960 ← divide both sides by 60
80 + 2x = 116 ( subtract 80 from both sides )
2x = 36 ( divide both sides by 2 )
x = 18

The number of students in a chess club decreased from 45 to 17. What is the percent decrease? Round
your answer to the nearest percent.
The percent decrease is
1%.
Answer:
original price =45
change in price=45-17= 28
precentage decrease = original price/change in price x 100
= 28 /45x 100
= 62.22%
Right triangle ABC is similar to right triangle DEF. If the side lengths for triangle ABC are 15, 20, 25, respectively, which values could represent the side lengths of triangle DEF
Answer:
[tex]A = 15[/tex] [tex]B = 20[/tex] [tex]C = 25[/tex]
[tex]D = 30[/tex] [tex]E = 40[/tex] [tex]F = 50[/tex]
[tex]D = 3[/tex] [tex]E = 4[/tex] [tex]F = 5[/tex]
Step-by-step explanation:
Given
Similar Triangles: ABC and DEF
[tex]A = 15[/tex]
[tex]B = 20[/tex]
[tex]C = 25[/tex]
Required
Determine the sides of DEF
No options were given, so I will solve on a general terms.
Since both triangles are similar, then the following relationship exists.
DEF = ABC * n
i.e.
[tex]D = A * n[/tex] [tex]E = B * n[/tex] [tex]F = C * n[/tex]
Where
[tex]n = Scale\ Factor[/tex]
Assume n = 2.
So, we have:
[tex]D = A * n[/tex]
[tex]D =15 *2[/tex]
[tex]D = 30[/tex]
[tex]E = B * n[/tex]
[tex]E = 20 * 2[/tex]
[tex]E = 40[/tex]
[tex]F = C * n[/tex]
[tex]F = 25 * 2[/tex]
[tex]F = 50[/tex]
Assume [tex]n = \frac{1}{5}.[/tex]
So, we have:
[tex]D = A * n[/tex]
[tex]D =15 *\frac{1}{5}[/tex]
[tex]D = 3[/tex]
[tex]E = B * n[/tex]
[tex]E = 20 * \frac{1}{5}[/tex]
[tex]E = 4[/tex]
[tex]F = C * n[/tex]
[tex]F = 25 * \frac{1}{5}[/tex]
[tex]F = 5[/tex]
So, the possible sides are:
[tex]A = 15[/tex] [tex]B = 20[/tex] [tex]C = 25[/tex]
[tex]D = 30[/tex] [tex]E = 40[/tex] [tex]F = 50[/tex]
[tex]D = 3[/tex] [tex]E = 4[/tex] [tex]F = 5[/tex]

tire rim has a diameter of 15 in. What is the circumference of the tire rim? Use 3.14 for Pi.
23.55 in.
46.10 in.
47.1 in.
94.2 in.
Answer:
The correct option is C. 47.10 inches
Step-by-step explanation:
Diameter of the tire rim is given to be 15 inches
So, The radius of the tire rim will be 7.5 inches
Now, we need to find the circumference of the tire rim
And, The circumference of the tire rim is given by the formula :
Circumference = 2·π × radius
⇒ Circumference of the tire rim = 2 × 3.14 × 7.5
⇒ Circumference of the tire rim = 47.1 inches
Therefore, The correct option is C. 47.10 inches
Students voted for a new class president and the results are shown in the table.
A 2-column table with 3 rows. Column 1 is labeled Candidate with entries Rosalia, Jocelyn, Danny. Column 2 is labeled Votes with entries 124, 109, 111.
Frank wrote these ratios to describe the number of votes each candidate received compared to the total. Which one is wrong, and why?
124:344 344 to 111 StartFraction 109 Over 344 EndFraction
The denominator of the fraction is incorrect.
The numbers in the ratio 344 to 111 are written in the wrong order.
A colon cannot be used in a ratio.
The word "to" cannot be used to show a ratio.

Emma bought a sweater that was 20% off. She paid $36 for the sweater, What was the original cost of the sweater?
Please hurry!
Answer:
$45
Step-by-step explanation:
let's work backwards. We know that it was 20% off, or otherwise 80% of the original cost. Let's represent the original cost with x:
0.8x = 36
Now we solve for x by dividing both sides by 0.8:
x = 45
Thus, the sweater was originally $45

Solve for h.
h/10 + 5 = 25
so what’s h ??
Answer:
h=200
Step-by-step explanation:
h/10+5=25
h/10=20
h=200
h/10 + 5 = 25
Subtract 5 from each side to get h/10 alone.
h/10 + 5 - 5 = 25 - 5
h/10 = 20
Multiply both sides by 10 to get h alone.
h/10 • 10 = 20 • 10
h = 200
h = 200. I hope this helps!

Solve for y:-4x+2y=6
Step-by-step explanation:
just going tell u to use math
way
Answer: B
Step-by-step explanation:
-4x + 2y = 6 add 4x to both sides
+4x +4x
2y = 4x + 6 Divide both sides by 2
y = 2x + 3
Solve the system using substitution.
2x = 5y + 14
x = 5y
Answer:
y = 2.8x = 14Step-by-step explanation:
To solve an equation, we can only have one variable. In this case, we are given the system 2x = 5y + 14. However, we are given the value of x in terms of y. We can substitute 10y in for 2x and solve.
10y = 5y + 14
First, we need to get all the variables on one side of the equation, so we subtract 5y.
5y = 14
Divide by 5
y = 14/5 or 2 4/5 or 2.8
Now for the x part.
2x = x + 14
Subtract 1x
x = 14
Now we check our answer.
2(14) = 5(2.8) + 14
28 = 14 + 14
28 = 28
Because 28 equals 28, our solutions are correct.
Whats the equation and slope Brainlyest to whoever gets right + 20 PTS
Answer:
Equation: y = 1/5x - 2
Slope (m): 1/5
The graph of the line equation y = 1/5x - 2 is also attached below.
Step-by-step explanation:
The slope-intercept form of the line equation
[tex]y = mx+b[/tex]
where
m is the slopeb is the y-interceptGiven the ordered pairs
(5, -1)(-5, -3)Finding the slope between the points (5, -1) and (-5, -3)
[tex]\mathrm{Slope}=\frac{y_2-y_1}{x_2-x_1}[/tex]
[tex]\left(x_1,\:y_1\right)=\left(5,\:-1\right),\:\left(x_2,\:y_2\right)=\left(-5,\:-3\right)[/tex]
[tex]m=\frac{-3-\left(-1\right)}{-5-5}[/tex]
Refine
[tex]m=\frac{1}{5}[/tex]
Thus, the slope (m) = 1/5
Also given that the y-intercept b = -2
Now, substituting m = 1/5 and y-intercept b = -2 in the slope-intercept form
y = mx+b
y = 1/5x + (-2)
y = 1/5x - 2
Therefore, the equation of the line is:
y = 1/5x - 2The graph of the line equation y = 1/5x - 2 is also attached below.
