Answer:
26m
Step-by-step explanation:
The diagonals of a parallelogram bisects each other. Hence the length of UV is equal to the length of VS
UV = VS
x+3 = 2x-7
x-2x = -7-3
-x = -10
x = 10
Get SU
SU = UV+VS
SU = x+3+2x-7
SU = 3x-4
Substitute x=10 into the expression
SU = 3(10)-4
SU = 30-4
SU = 26m
Length of SU is 26m

Constance can decorate 2 ornaments in 4 hour.
Part A: How many ornaments, per hour, can Constance decorate? Explain your
answer and show your work.
Your answer
This is a required question
Answer:
1/2 ornament in an hour
Step-by-step explanation:
Given
[tex]Orna\ ments = 2[/tex]
[tex]Time = 4[/tex]
Required
Determine the ornaments per hour
This question implies that we calculate the unit rate.
[tex]Unit\ Rate = \frac{Orna\ ments}{Time}[/tex]
Substitute values for Time and number of ornaments
[tex]Unit\ Rate = \frac{2}{4}[/tex]
[tex]Unit\ Rate = \frac{1}{2}[/tex]

A light bulb consumes 11700 watt-hours in 3 days and 6 hours. How many watt hours does it consume per day?
Answer:
3600 watt-hours consumed per day.
Step-by-step explanation:
First we'll want to find how many hours are in 3 days and 6 hours.
3 x 24 = 72 + 6 = 78
78 hours is 3 days and 6 hours.
We then divide 11700 by 78 to find out how many watt-hours it will consume per hour.
11700 / 78 = 150
Now that we know how many watt-hours it will consume per hour, we can multiply it by 24 to find out how many it will consume in a day.
150 x 24 = 3600

Given:
The figure of a triangle.
To find:
The value of x.
Solution:
According to the triangle proportionality theorem, if a line segment divides the two sides of a triangle and parallel to the third side of the triangle, the it divides the two inclined sides proportionally.
Using triangle proportionality theorem, we get
[tex]\dfrac{2x}{80}=\dfrac{27}{60}[/tex]
[tex]\dfrac{x}{40}=\dfrac{9}{20}[/tex]
Multiply both sides by 40.
[tex]x=\dfrac{9}{20}\times 40[/tex]
[tex]x=9\times 2[/tex]
[tex]x=18[/tex]
Therefore, the value of x is 18.

Answer:
The first one is 3x-2=-20. So the - 2 will cross the equal sign making it positive so it will be 3x = -20+2 given you 3x = - 18. You will divide it by 3 given u - 6. So all of them x= - 6

10. A line with a negative slope and a negative
y-intercept is graphed on a coordinate
plane. Which quadrant will the line not pass
through? Justify your response.
Answer:
The line will not pass through the first quadrant.
Step-by-step explanation:
Since the y-intercept is negative, and the slope is negative, the line will start in the second quadrant, pass through the third quadrant to intercept the y-axis, then pass through the fourth quadrant. It will never touch the first quadrant.

1. How much water should be added to 8 mL of 6% saline solution to reduce the concentration to 4%?
Answer:
Amount of active ingredient is 0.04(8+x)= 0.32+0.4x
---------------
EQUATION:
active ingre. + active ingre. = active ingre
0.48 + 0 = 0.32 + 0.04x
0.16 = 0.04x
x=4ML (amount of water that must be added)
The amount of water that must be added is 4 ml to 8 mL of 6% saline solution to reduce the concentration to 4%.
What is the percentage?It's the ratio of two integers stated as a fraction of a hundred parts. It is a metric for comparing two sets of data, and it is expressed as a percentage using the percent symbol.
It is given that:
8 mL of 6% saline solution to reduce the concentration to 4%.
Let x be the amount that should be added to 8 mL of 6% saline solution to reduce the concentration to 4%.
The amount of active ingredients is
0.04(8 + x) = 0.32 + 0.4x
Active ingredients + active ingredients = active ingredients
0.48 + 0 = 0.32 + 0.04x
0.16 = 0.04x
x=4 ml; the amount of water that must be added
Thus, the amount of water that must be added is 4 ml to 8 mL of 6% saline solution to reduce the concentration to 4%.

In quadrilateral PQRS below, sides PS and QR are parallel for what value of x ?
158
132

70
Answer:
ps and qr is parellel so the 70°and x is co interior angles.
so, our equation will be look like .
70°+x=180°
x=180°-70°
x=110°
The sides PS and QR are parallel for x = 110°
Option 4 is correct.
What are consecutive-interior angles?The pair of non-adjacent interior angles that are on the same side of the transversal are referred to as consecutive internal angles.The term "consecutive" describes events that take place side by side.
As per the given data:
PQRS is a quadrilateral with sides PS and QR parallel.
∠P = 70°
∠Q = x°
∠S = 112°
For sides PS and QR to be parallel:
∠Q + ∠P = 180° {Co-interior angles on the same side of the transversal}
x° + 70° = 180°
x = 110°
Hence, sides PS and QR are parallel for x = 110°

Last year, Maya opened an investment account with 8,800. At the end of the year, the amount in the account had decreased by 26.5%. How much is this decrease in dollars? How much money was in her account at the end of last year?
Answer:
Results are below.
Step-by-step explanation:
Giving the following information:
Initial investment= $8,800
Percentage decrease= 26.5%
To calculate the money Maya lost, we need to use the following formula:
Decrease on dollars= 8,800*0.265
Decrease in dollars= $2,332
At the end of the years she has:
Money left= 8,800 - 2,332

At the beginning of the year, the number of books owned by a library was 10,000. Since then, it has grown by 1% each month.
Which expressions represent the number of books, in thousands, owned by the library 5 years later if it continues to grow at that rate?
Answer:
y = 10(1.01)^60
Step-by-step explanation:
The general equation of exponential growth is
y = ab^x
b has to do with the rate of growth.
b = 1 + r, so in this case, b = 1 + 1% = 1 + 0.01 = 1.01.
Now we have
y = a(1.01)^x
a is the initial value, so now we have
y = 10000(1.01)^x
where y is the number of books after x months
Since you need the number of books after 5 years, we must convert 5 years into months.
5 years * (12 months)/year = 60 months
The problem wants the expression in thousands of books, so we divide the initial value by 1000.
Answer: y = 10(1.01)^60
Expression representing the number of books after 5 years,
[tex]A(60)=10000(1.01)^{60}[/tex]
Exponential growth: Exponential growth function is given by,[tex]A(t)=A_0(1+r)^t[/tex]
Here, [tex]A(t)=[/tex] Final amount
[tex]A_0=[/tex] Initial amount
[tex]r=[/tex] Growth rate
[tex]t=[/tex] Duration or time
Given in the question,
Initial number of books = 10000 Growth rate = 1% Duration = 5 years ≈ 60 monthsSubstitute these values in the expression,
[tex]A(t)=A_0(1+r)^t[/tex]
[tex]A(60)=10000(1+0.01)^{60}[/tex]
Therefore, expression representing the number of books after 5 years will be → [tex]A(60)=10000(1.01)^{60}[/tex]

Step-by-step explanation:
So first of all you want to start by finding what P, r and t would be.
P = Principal amount ($$)
r = interest rate (%)
t = time (years)
