If triangle ABC is similar to triangle PQR, find the value of x and y.
Answer:
x = 9
y = 6
Step-by-step explanation:
ΔABC ~ ΔPQR
Therefore, corresponding sides of these similar triangles will be in the proportional.
[tex]\frac{AB}{PQ}=\frac{BC}{QR}= \frac{AC}{PR}[/tex]
[tex]\frac{6}{x}= \frac{4}{y}= \frac{8}{12}[/tex]
[tex]\frac{6}{x}= \frac{8}{12}[/tex]
x = [tex]\frac{12\times 6}{8}[/tex]
x = 9
Similarly, [tex]\frac{4}{y}= \frac{8}{12}[/tex]
y = [tex]\frac{12\times 4}{8}[/tex]
y = 6

Answer:
C. 3⁶
Step-by-step explanation:
Exponents with the same base follow this exponential rule for division:
xᵃ/xᵇ = xᵃ⁻ᵇWhen the bases are the same, we can subtract the exponents.
The bases are the same in this problem: 3. Therefore, we can subtract the exponents from each other:
3⁸/3² 3⁸⁻² 3⁶The final and correct answer is C. 3⁶.

A blackboard has an area of 28 ft2 and a perimeter of 22 ft. What are the dimensions of the board?
2 ft by 11 ft
2 ft by 14 ft
4 ft by 7 ft
7 ft by 7 ft
Answer:
Step-by-step explanation:
A=LW, L=A/W
P=2(L+W), using L=A/W we get
P=2(A/W+W)
P=2(A+W^2)/W
PW=2A+2W^2
2W^2-PW+2A=0, given A=28 and P=22 we have
2W^2-22W+56=0
2(W^2-11W+28)=0
2(W-7)(W-4)=0
So the dimensions are 4ft by 7ft

Write an equation of the line that passes through point (2, -1) and is perpendicular to y = 2/3 x - 4.
Answer:
y=-3x/2+2
Step-by-step explanation:
slope of original line : 2/3
slope of line perpendicular:
(m)(2/3)=-1
m=-3/2
point slope form:
(y+1)/(x-2)=-3/2
2y+2=-3x+6
y=-3x/2+2

In order to graph a line from an equation that is written in slope intercept form, what do you plot first, then next.
O plot (b) first, then plot 9mo to rise and run to find other points.
O just plot the (b) on the y-axis only.
O plot (b) on the X-axis, then (m) on the y-axis.
Oplot (m) first to rise and run to find other points, then plot (b)
Answer:
first answer - you plot 'b' [on the y-axis] first, then use the slope m = c/d to go d units right and then c units up (positive 'c') or down (negative 'c')
Step-by-step explanation:
plot 'b' [on the y-axis] first, then use the slope m = c/d to go d units right and c units up (positive 'a') or down (negative 'a')
It has to be the first answer (in spite of the typo here), because all the others are wrong

[tex]y=3\frac{3}{5}[/tex]
Answer: The answer would be 3.6
You first want to add 4 to both sides to get y on one side by itself. So it would look something like this: -2/5+4=y. Then you can add which gives you y=3.6

Which equation shows a slope of 2/3 and a y-intercept of (0,-2) ?
Answer:
Y=2/3x -2
Step-by-step explanation:
Slope 2/3
Y intercept -2
The equation which has a slope of 2/3 and a y-intercept of (0, -2) is; 2x -3y = 6
Slope and y-intercept of straight line equationsFrom line geometry, it follows that the slope of a given straight line is the rate of change in variable y due to a change in variable x.
Hence, the resulting equation is;
2/3 = (y -(-2))/(x-0)By cross-multiplication;
3y + 6 = 2x.Read more on equation of a line;

12% of students of a class of 50 like blue
colour. How many children like blue colour?
Answer:
6 children
Step-by-step explanation:
(12*50)/100
If 12% of students of a class of 50 like blue colour, the number of children that like blue is 6
The number of students in the class = 50
12% of the total number of students like blue
Number of students that like blue colour = 12% of 50
Number of students that like blue colour = (12/100) x 50
Number of students that like blue colour = 0.12 x 50
Number of students that like blue colour = 6
Therefore, if 12% of students of a class of 50 like blue colour, the number of children that like blue is 6
