Answer:
D. 4
Step-by-step explanation:
∆VWZ ~ ∆VXY, therefore:
[tex] \frac{VW}{VX} = \frac{VZ}{VY} [/tex]
VW = 8
VX = 8 + WX
VZ = 18
VY = 27
Plug in the values
[tex] \frac{8}{8 + WX} = \frac{18}{27} [/tex]
Cross multiply
[tex] 8 * 27 = (8 + WX)*18 [/tex]
[tex] 216 = 144 + 18WX [/tex]
Subtract 144 from each side
[tex] 72 = 18WX [/tex]
Divide both sides by 18
[tex] 4 = WX [/tex]
WX = 4
Mr. Logan spent 14 cents at the hardware store buying nails and screws. Nails cost 2 cents, and screws cost 1 cent. If Mr. Logan bought exactly 9 items, how many of each did he buy?
Please help me fast !!!
Answer:
5 nails and 4 screws
Step-by-step explanation:
Make it into an expression where N= amount of nails bought and S= amount of screws bought. Then set it equal to the amount he paid.
ie: 2n+1s=14
Now make another equation for how many he bought.\
ie: n+s=9
Now subtract one of the letter variables from the second equation to get one on alone.
ie: n=9-s
Now, since you have a value for N, substitute it for the value in the original equation so that there's only one variable.
ie: 2(9-s)+1s=14
Now solve for S.
ie: 18-2s+s=14
ie: -s=-4
ie: s=4
Now you have a number value for S that you can plug in the original equation to find the value of N.
ie: 2n+4=14
ie: 2n=10
ie: n=5
Now plug in your values for N and S into the original equation to check it. Your answer is 5 nails and 4 screws.

I tried to answer this one and got it wrong the question is “find the measure of each angle indicates”
Answer:
∠F = 80
Step-by-step explanation:
Let's find inner ∠D first, as you can see, it's a straight line but a line is in between, the outer angle is 120, and a straight line is 180, so 180 - 120 = 60. The inner ∠D is 60, now we can find ∠F, a triangle is 180:
40 + 60 + ∠F = 180
100 +∠D = 180
subtract 100 from both sides
∠F = 80

A carpenter is making a rectangular form for a concrete pad she wants the length of the path to be 11 feet more than the width of the bed the area of the concrete pad must be 80 ft.² write the quadratic equation that will be used to find the dimensions of the pad
Answer:
Length = 16 or -5 feet.
Width = 5 or -16 feet.
Step-by-step explanation:
Let the length of the concrete pad = l
Let the width of the concrete pad = w
Given the following data;
Area of concrete pad, a = 80ft²
Translating the word problem into an algebraic equation, we have;
[tex] l = 11 + w[/tex]
We know that, the area of rectangle, A = length * width
[tex] A = l*w[/tex]
Substituting the values into the equation, we have;
[tex] 80 = (11 + w)w[/tex]
Expanding the bracket, we have;
[tex] 80 = 11w + w^{2}[/tex]
[tex] w^{2} + 11w - 80 = 0[/tex]
*Solving the quadratic equation by using factorization method*
[tex] w^{2} + 16w - 5w - 80 = 0[/tex]
[tex] w(w + 16) - 5(w + 16) = 0[/tex]
[tex] (w - 5)(w + 16) = 0 [/tex]
Width, w = 5 feet or w = -16 feet.
Therefore, the width of the concrete pad is 5 feet or -16 feet.
To find its length, l;
[tex] l = 11 + w[/tex]
When w = 5 feet
[tex] l = 11 + 5[/tex]
Length, l = 16 feet
When w = - 16 feet
[tex] l = 11 + (-16)[/tex]
[tex] l = 11 - 16[/tex]
Length, l = -5 feet.
Hence, the dimensions of the concrete pad is 16 by 5 feet or -5 by -16 feet.
If f(x)= x^2-2x+3, find the value of f (-2) and f(3)
Step-by-step explanation:
Given
f(x) = x² - 2x + 3
Now
f(-2) = (-2)² - 2 * ( -2 ) + 3
= 4 + 4 + 3
= 11
f(3) = 3² - 2 * 3 + 3
= 9 - 6 + 3
= 12 - 6
= 6

the uniform distribution over the interval 8.5 to 11.5 gallons per minute. Find the probability that between 9.0 gallons and 10.0 gallons are pumped during a randomly selected minute.
Answer: 1/3
Step-by-step explanation:
Here is the complete question:
machine is set to pump cleanser into a process at the rate of 9 gallons per minute. Upon inspection, it is learned that the machine actually pumps cleanser at a rate described by the uniform distribution over the interval 8.5 to 11.5 gallons per minute. Find the probability that between 9.0 gallons and 10.0 gallons are pumped during a randomly selected minute.
The Probability of the above question will be calculated as:
= (10-9) / (11.5 - 8.5)
= 1/3
The above is the easier way to solve this

A bag contains 70 coins consisting of quarters and dimes. The total value of coins is $11.50. Which system of equations can be used to determine
the number of quarters, q, and the number of dimes, d, in the bag?
A. d+9= 70
0.100 +0.25q = 11.50
B. d + 9 = 70
0.25d + 0.107 = 11.50
C. d+q = 11.50
0.25d + 0.10g = 70
D. d +9 = 11.50
0.100 +0.25= 70

what is the equation of the line that has a slope of 5 and passes through the point (2,7)?
Answer:
[tex]y = 5x - 3[/tex]
Step-by-step explanation:
Given
[tex]Slope, m = 5[/tex]
[tex](x_1,y_1) = (2,7)[/tex]
Required
Determine the line equation
Using slope intercept form, the line equation can be calculated using:
[tex]y - y_1 = m(x - x_1)[/tex]
Substitute values for m, x1 and y1. The equation becomes
[tex]y - 7=5(x - 2)[/tex]
Open Bracket
[tex]y-7 = 5x - 10[/tex]
Add 7 to both sides
[tex]y-7+7 = 5x - 10+7[/tex]
[tex]y = 5x - 3[/tex]
Hence, the line equation is: [tex]y = 5x - 3[/tex]
