Is quadrilateral UVWX a parallelogram? Why or why not?
Answer:
C
Step-by-step explanation:
Slope of UV = 0 = Slope of XW
So UV is parallel to XW.
Slope of UX = [6-(-4)]/[-7-(-3)] = -5/2
Slope of VW = [6-(-4)]/(0-4) = -5/2
Slope of UX = Slope of VW i.e. UX is parallel to VW.
It is a parallelogram because opposite sides are parallel.
Answer:
Yes, because opposite sides are parallel.

Rob and Matt made 55 cups of lemonade
for their lemonade stall. Rob made 7 more
lemonades than Matt.
How many lemonades did Matt make?
Answer:
Rob made 31, and Matt made 24
Step-by-step explanation:
55 in total
Rob made 7 more do 55 - 7 = 48
48 / 2 = 24
24 for Matt
24 +7 = 31
31 for rob
Answer:
24 cups of lemonade
Step-by-step explanation:
Rob made 7 more then Matt. You could say that Matt made 24 and Rob made 31 and it would be correct.
-10 = -0.2k
k = ?
solve for k
Answer:
-10 = -0.2k
we multiply both sides by 5
-50 = -k
k = 50

Jane works at The Bottling Company. She needs to put 8,500 bottles of water into cases. So far she has put 2,136 in cases. How many cases can Jane fill with the remaining bottles? How many bottles will be left?
Answer:
6364 cases
6364 bottles are left
Step-by-step explanation:
From the question, we are given the following
Total bottles of water = 8500bottles
Total cases filled = 2136cases
Required
Number of cases Jane can film with the remaining bottle.
Number of cases Jane can fill = 8500-2136
Number of cases Jane can fill with the remaining bottle= 6364 cases
Number of bottles left = number of cases Jane have left to fill.
Hence;
Number of bottles left = 6364 bottles

Answer:
7. x = 5
8. x = 2, y = 6
9. x = 21, y = 39
Step-by-step explanation:
For a parallelogram, the lengths across intersection are equal.
7. For a parallelogram, the lengths across intersection are equal.
So that,
3x = 4x - 5
4x - 3x = 5
x = 5
8. For a parallelogram, the lengths across intersection are equal.
So that,
2x = 4
x = [tex]\frac{4}{2}[/tex]
x = 2
and
y - 1 = 2y -7
7 - 1 = 2y - y
y = 6
x = 2, y = 6
9. For a parallelogram, opposite angles have equal value.
Thus,
3x = (4x - 21)
3x = 4x - 21
x = 21
and
3y = (y + 78)
3y = y + 78
3y - y = 78
2y = 78
y = [tex]\frac{78}{2}[/tex]
= 39
y = 39
x = 21, y = 39
Please help i have no idea what this is :(
Answer: y - 3= -1/2 * (x - 8)
Answer:
y=-1/2x+3
Step-by-step explanation:
Slope intercept form is written: y=mx+b...
y=doesn't change, but you need it by itself
m=slope
x=the variable right next to the slope
b=y-intercept
Also, don't worry! This is super simple ^^
The question gives us -1/2 as the slope, so it needs to be plugged into the equation as m (next to x). Now our equation looks like this:
y=-1/2x+b
Next, we can figure out b. B is the y-intercept and we can figure this out by looking at the ordered pair (8, 3). The y is the second number, which is 3, so that is the y-intercept! We can now plug in 3 into b. Our final equation looks like this:
y=-1/2x+3
Hope this helps!! Have an awesome day ❤
Lehana and Marty each opened a savings account with a deposit of $100.
● Lehana earned 2.5% simple interest per year.
● Marty earned 2% simple interest per year.
● Neither of them made additional deposits or withdrawals.
How much more did Lehana receive in interest than Marty after three years?
Answer:
100*.025*3=7.5 100+7.5=107.5
100*.02*3=6 100+6=106

Annie buys a surfboard online for $ 44. If shipping and handling are an additional 20% of the price, how much shipping and handling will Annie pay?
PLSSSSSSSSSSSSSSSSSSSSSSSSSS HELP BRAINLEST
Answer:
Annie buys a surfboard online for $ 44. The shipping and handling are an additional 20% of the original price.
Amount of money she will pay for shipping and handling is
[tex]20\% \: of \: \$44 \\ \frac{20}{100} \times 44 = \frac{1}{5} \times 44 = \boxed{\$8.8}[/tex]
She should pay $8.8 for the shipping and handling.
Find the missing length marked with a question mark.
UVW-USR
Given:
[tex]\Delta UVW\sim \Delta USR[/tex]
To find:
The missing length marked with a question mark.
Solution:
Let x be the missing value.
We have,
[tex]\Delta UVW\sim \Delta USR[/tex]
Corresponding sides of similar triangles are proportional, so
[tex]\dfrac{UV}{US}=\dfrac{VW}{SR}=\dfrac{UW}{UR}[/tex]
Using this, we get
[tex]\dfrac{UV}{US}=\dfrac{UW}{UR}[/tex]
On substituting the values, we get
[tex]\dfrac{70}{x}=\dfrac{55}{44}[/tex]
[tex]\dfrac{70}{x}=\dfrac{5}{4}[/tex]
On cross multiplication, we get
[tex]70\times 4=5\times x[/tex]
[tex]280=5x[/tex]
[tex]\dfrac{280}{5}=x[/tex]
[tex]56=x[/tex]
Therefore, the missing length is 56 units.

Kieran, Jermaine and Chris play football.
Kieran has scored 8 more goals than Chris.
Jermaine has scored 5 more goals than Kieran.
Altogether they have scored 72 goals.
How many goals did they each score?
Step-by-step explanation:
Find an equation that explains the problem. We can see how many goals the players have scored in comparison to each other. The person with the fewest goals is Chris. Let us say he score x goals. Then we can see that Kieran has scored 8 more than Chris, i.e. x + 8. Jermaine scored 5 more goals than Kieran, therefore x + 8 + 5 = x + 13. Now we have the amount of goals each person scored relative to each other. The total number of goals scored was 72, thus all of these amounts must equal 72.
x + (x + 8) + (x + 13) = 72
Now we can rearrange and solve for x.
3x + 21 = 72
3x = 51
x = 17

QS bisects <PQR. If m<PQS = 5x and m<RQS = 2x + 6, then what is m<PQR?
Answer:
20 degrees
Step-by-step explanation:
If QS bisects Angle PQR, it would mean that Angle PQS and Angle RQS are equal
2x+6=5x
Subtract 2x on both sides
6=3x
Divide by 3 on both sides
x=2
Plug the value of x into either one of the angle measures equation
5x
5(2)=10
If they are equal to one another it would mean that the other angle would be the same measure and you would multiply it by 2
10(2)=20
Therefore 20 degrees is the answer for the measure of Angle PQR
Hope it helped :))
11. Sara borrowed *60,000 from a money lender at 15% rate of interest per annum. What is
the interest she paid after 4 years?
Answer:
36000
Step-by-step explanation:
Given the following
Principal = 60,000
Rate = 15%
Time = 4years
Using the simple interest formula
SI = PRT/100
SI = 60000*15*4/100
SI = 600 * 60
SI = 36,000
Hence the interest paid after 4 years is 36000
