Answer:
These are similar triangles.
By changing the length of the base of the corresponding triangle, the 3 interior angles of this triangle remain equal to the original
Therefore, if these triangles are similar, their corresponding sides must give equal ratios to each other:
This means that BF/FE = BC/CD=FC/ED
The total length of line segment BD=BC+CD; BC=6, CD=42; BD=6+42, BD=48
BE=BF+FE; BE=9+?
if BF/FE=BC/CD then 9/BE=6/42; 6/42=3/21 or 1/7. 9/BE=1/7; 1/7=9/BE
1x9=9, 7x9=63
63=BE
Step-by-step explanation:
Answer:BE is equal to 72.
Step-by-step explanation: They are similar triangles. We know CD and BC. So we can find the comparison between the two. And we see that BC x 7 = CD. So the same will be said for BF and FE. We have BF is equal to 9. So 9 x 7 = 63. However, now we need to add the two together in order to get BE. Because BF + FE = BE. So 9 + 63 = 72

2. A solar lease customer built up an excess of 6,500 kilowatt hours (kwh) during the summer using his solar

per day.
(a) If E represents the excess left and d represents (b) How much of the excess will be left after one
the number of days since the heat has been month (use a month length of 30 days)?
turned on, write an equation for E in terms of d.
(c) If the heat will need to be turned on for 5 months, will the excess be enough to last through this time
period? Justify your answer.
Answers
9514 1404 393
Answer:
a) E = 6500 -50d
b) 5000 kWh
c) the excess will last only 130 days, not enough for 5 months
Step-by-step explanation:
Given:
starting excess (E): 6500 kWh
usage: 50 kWh/day (d)
Find:
a) E(d)
b) E(30)
c) E(150)
Solution:
a) The exces is linearly decreasing with the number of days, so we have ...
E(d) = 6500 -50d
__
b) After 30 days, the excess remaining is ...
E(30) = 6500 -50(30) = 5000 . . . . kWh after 30 days
__
c) After 150 days, the excess remaining would be ...
E(150) = 6500 -50(150) = 6500 -7500 = -1000 . . . . 150 days is beyond the capacity of the system
The supply is not enough to last for 5 months.

What is 116.52 plus 8% as tax
Answers
Answer:
125.84
Step-by-step explanation:
116.52(0.08)=9.32
116.52+9.32=125.84
Answer:
The total is $125.84.
Step-by-step explanation:
The total is equal to the original value (100%) + the tax amount (8%) which equals 108%. To multiply it, we move the decimal two to the left to get our figure (1.08) then multiply that times 116.52. So, 116.52x1.08=125.8416; for dollars I rounded to the nearest cent: $125.84.

In ΔWXY, the measure of ∠Y=90°, XW = 89, WY = 80, and YX = 39. What ratio represents the cosine of ∠X?
Answers
Answer:
It's 39/89
Step-by-step explanation:
cos X = adjacent/ hypotenuse = 39/89
[tex]\frac{39}{89}[/tex] represents cosine of ∠X.
What is cosine?
'In a right-triangle, cos is defined as the ratio of the length of the adjacent side to that of the longest side which is the hypotenuse.'
According to the given problem,
In the right angle triangle ΔWXY,
Hypotenuse = XW = 89
Perpendicular = WY = 80
Base = YX = 39
We know,
cos∅ = [tex]\frac{Base}{Hypotenuse}[/tex]
⇒ cosX = [tex]\frac{39}{89}[/tex]
Hence, we can conclude that the ratio [tex]\frac{39}{89}[/tex] represents the cosine of ∠X

Answers
Answer:
8.314, 8.356, 8.36, 8.43, 8.475, 8.5
^ This is the numbers from least to greatest, 8.314 being the least and 8.5 being the greatest.
Step-by-step explanation:
First, start off with the lowest number. You will see that each number starts with 8, so we go to the next number. You will now see three numbers having the number 3 in the second place. Now, we go to the next digit after that.
1 is less than 5 and 6, and 5 is less than 6.
This means that the 1 will go first, followed by the 5, then the 6.
Now we see that there are two numbers with a 4 in the second decimal place. The next number after that will now determine where it goes.
3 is less than 7, so that means 3 will come before 7.
The digit 5 is the greatest, so it will be at the end of the list.

Which equation matches the graph?
In the xy graph, the range of the x axis is zero to four by increment of one. The range of y axis is zero to eight by increment of one. On both axes every alternate tick mark is labeled. On the graph, there is a line passing through the points (2, 2) and (0, 8).
Answers
Answer:
[tex]y = -3x +8[/tex]
Step-by-step explanation:
The graph diagram is not given; however, the equation can be solved from the given points
(2,2) and (0,8)
This is represented as:
[tex](x_1,y_1) = (2,2)[/tex]
[tex](x_2,y_2) = (0,8)[/tex]
Calculate slope (m)
[tex]m = \frac{y_2 - y_1}{x_2 - x_1}[/tex]
[tex]m = \frac{8 - 2}{0 - 2}[/tex]
[tex]m = \frac{6}{- 2}[/tex]
[tex]m =-3[/tex]
The equation is calculated using:
[tex]y - y_1 = m(x - x_1)[/tex]
[tex]y - 2 = -3(x - 2)[/tex]
[tex]y - 2 = -3x + 6[/tex]
Add 2 to both sides
[tex]y - 2 +2= -3x + 6+2[/tex]
[tex]y = -3x + 6+2[/tex]
[tex]y = -3x +8[/tex]

You bought 5 chocolate bars and 8 blow pops for $23.25. Your sister bought 2 chocolate bars and 13 blow pops for $21.55. How much did each chocolate
bar cost? Each chocolate bar cost?
Answers
Answer:
Cost of each chocolate bar = $2.65
Cost of each blow pop = $1.25
Step-by-step explanation:
Let x = Cost of chocolate bar
y= Cost of blow pops
We can make system of equations and find value of x and y
You bought 5 chocolate bars and 8 blow pops for $23.25.[tex]5x+8y=23.25[/tex]
Your sister bought 2 chocolate bars and 13 blow pops for $21.55. [tex]2x+13y=21.55[/tex]
Let:
[tex]5x+8y=23.25--eq(1)\\2x+13y=--eq(2)[/tex]
Multiply eq(1) with 2 and eq(2) with 5 and subtract
[tex]10x+16y=46.5\\10x+65y=107.75\\- \ \ \ - \ \ \ \ \ \ - \\------\\-49y=-61.25\\y=\frac{-61.25}{-49} \\y=1.25[/tex]
So, value of y = 1.25
Putting value of y in eq(1) to find value of x
[tex]5x+8y=23.25\\5x+8(1.25)=23.25\\5x+10=23.25\\5x=23.25-10\\5x=13.25\\x=13.25/5\\x=2.65[/tex]
Value of x = 2.65
So, Cost of each chocolate bar = x = $2.65
Cost of each blow pop = y = $1.25

Use parentheses to show two ways of grouping the numbers in 12 • 8 • 25. Tell which expression you think would be easier to simplify, and why. Then simplify the expression.
Answers
Step-by-step explanation:
First no. is 12
Second no. is 8
Third no. of 25
Way 1 of grouping the numbers,
(12×8)×25
We can use associative law of multiplication as follows :
(a×b)×c = a×(b×c)
(12×8)×25 = (96) × 25
= 2400
Way 2,
12×(8×25) = 12 × 200
= 2400
Way 2 is easier to simplify because when we multiply 8 and 25, we get 200. It is very easy to multiply any number with a number that have zeroes. As a result we easily get the answer i.e. 2400.
