Answer:
WZ = 30
Step-by-step explanation:
set up equation based on WZ = W'Z'
3/4[6x + 10] = 13x - 35
multiply each side of equation by 4 to eliminate fractions:
18x + 30 = 52x - 140
-34x = -170
x = 5
substitute 5 for 'x' in either expression:
13(5) - 35
65 - 35 = 30
Answer:
[tex] \frac{3}{4} (6x + 10) = 13x - 35 \\ [/tex]

Step-by-step explanation:
A chemist has a mixture with a temperature of 3.5°C. Then the chemist cools the mixture. The temperature changes by -14.2°C. What is the temperature of the mixture after it cools? Show your work.
Answer:
-10.7°C
Step-by-step explanation:
The change in the temperature is the difference between the initial temperature and the final temperature. Let the initial temperature be T1 and the final be T2 then the change in temperature will be
= T2 - T1
Hence
-14.2 = T2 - 3.5
T2 = -14.2 + 3.5
= - 10.7°C
The temperature of the mixture after it cools is -10.7°C

Answer:
x = 4
Step-by-step explanation:
Using the sine ratio in right Δ JKL and exact value
sin30° = [tex]\frac{1}{2}[/tex] , then
sin30° = [tex]\frac{opposite}{hypotenuse}[/tex] = [tex]\frac{JL}{KL}[/tex] = [tex]\frac{JL}{8\sqrt{2} }[/tex] = [tex]\frac{1}{2}[/tex] ( cross- multiply )
2JL = 8[tex]\sqrt{2}[/tex] ( divide both sides by 2 )
JL = 4[tex]\sqrt{2}[/tex]
---------------------------------------------------------------
Using the sine ratio in Δ JLM and exact value
sin45° = [tex]\frac{1}{\sqrt{2} }[/tex] , then
sin45° = [tex]\frac{ML}{JL}[/tex] = [tex]\frac{x}{4\sqrt{2} }[/tex] = [tex]\frac{1}{\sqrt{2} }[/tex] ( cross- multiply )
x × [tex]\sqrt{2}[/tex] = 4[tex]\sqrt{2}[/tex] ( divide both sides by [tex]\sqrt{2}[/tex] )
x = 4
Answer:
4
Step-by-step explanation:
When explaining my solution I will assume that you know SOH CAH TOA. If you don't leave a comment below and I will explain it
We know the line KL and angle K which is enough to get the rest of the lenghts of this triangle
Using CAH we have
Cos30=x/8sqrt2
solve for x and get
8sqrt2Cos30=x
Put this into your calculator and get that line KJ= 9.7979
With this we can solve for the rest of the trinagle using a^2+b^2=c^2
So we have
9.7979^2+LJ^2=(8sqrt2)^2
Compute what you can and get x by itself to get
LJ^2=32
LJ=sqrt32 which is 5.6568
Now that we know the length of line LJ we can solve the second part of the triange.
Knowing that the hypotonous is equal to 5.6568 and angle j=45 we can use SOH
we have
sin45=x/5.6568
Solve this and get
5.6568sin45=4

Find the value of 5^-3 x 2^-1
Answer:
1/250
Step-by-step explanation:
5^-3 × 2^-1
5^-3 = 1/5^3 = 1/125
2^-1 = 1/2^1 = 1/2
so 5^-3 × 2^-1 means 1/125 × 1/2
= 1/125 × 1/2
= 1/250

Indicate in standard form the equation of the line passing through the given points, writing the answer in the equation box below
R(3,3) S(-6,-6)
Answer:
[tex] \frac{(y - 3)}{(x - 3)} = \frac{( - 6 - 3)}{( - 6 - 3)} = \frac{( - 9)}{( - 9)} = 1 \\ \frac{(y - 3)}{(x - 3)} = 1 \\ y - 3 = x - 3 \\ \boxed{y = x}[/tex]
Slope of the equation is 1 and intercept of the equation is 0.
Coffee café mix 90 pounds of coffee that cost six dollars per pound the types of coffee used to make this makes you cost seven dollars and four dollars per pound how many pounds of the seven dollar per pound coffee should be used in this mixture
Answer:
y = 60
Step-by-step explanation:
From the information we get:
x quantity of 4 dollars coffee used in the mix
y quantity of 7 dollars coffee used in the mix
For the quantity of coffee to be sold a 7 $/pound ( 90 pounds)
Then 6*90 = 540 $
Therefore
x + y = 90 and
4*x + 7*y = 540
A two equations system we solve for x and y
y = 90 - x
4*x + 7* ( 90 - x ) = 540
4*x + 630 - 7*x = 540
- 3*x = - 90
x = 30 pounds and
y = 90 - 30
y = 60
We should use 60 pounds of the seven $ coffee
If this pattern continues how many squares will be in the 10th figure

A triangle has side lengths of (3a – 7),
(a + 14), and (2a + 1). What simplified
expression represents the perimeter of the
triangle?
Answer:
6a+8
Step-by-step explanation:
To find the perimeter of a shape add all the sides up
To do this just add everything together
this means we have
3a-7+a+14+2a+1
Add like terms and get
6a+8

Find the area of the
regular figure below:
A) 466 mm2
B) 430 mm2
C) 404 mm2
D) 495 mm2
E) 512 mm2
explain pls
Answer:
Option A
Step-by-step explanation:
Central angle of the pentagon = [tex]\frac{360}{\text{Number of sides of the regular polygon}}[/tex]
= [tex]\frac{360}{5}[/tex]
= 72°
Measure of ∠BAC = 72°
Therefore, measure of ∠BAD = [tex]\frac{72}{2}[/tex]
= 36°
By sine rule in ΔABD,
sin(36°) = [tex]\frac{\text{Opposite side}}{\text{Hypotenuse}}[/tex]
= [tex]\frac{BD}{AB}[/tex]
= [tex]\frac{BD}{14}[/tex]
BD = 14(sin36°)
= 8.23 mm
Similarly, by cosine rule,
cos(36°) = [tex]\frac{\text{Adjacent side}}{\text{Hypotenuse}}[/tex]
= [tex]\frac{AD}{AB}[/tex]
= [tex]\frac{AD}{14}[/tex]
AD = 14(cos36°)
= 11.33 mm
Area of ΔABC = 2(Area of ΔABD)
= [tex]2(\frac{1}{2}(\text{Base})(\text{Height})[/tex]
= AD × BD
= 11.33 × 8.23
= 93.21 mm²
Since, area of regular pentagon given in the picture = 5(area of ΔABC)
= 5(93.21)
= 466 mm²
Therefore, Option A will be the answer.

Shelby's total earnings will be the sum of the amount she has earned and the amount she can earn working h hours. That latter amount is 25h, since she makes $25 per hour. She wants that total to be at least $2000.
75 + 25h ≥ 2000
Dividing by 25 gives ...
3 +h ≥ 80
subtracting 3, we have ...
h ≥ 77
