Give the coordinates of the unknown vertex of rectangle JKLM. The vertices are A(3,1), B(3,-1), and C(-2,-1). What are the coordinates of vertex D?
Answer:
(-2,1) Plz give me brainliest!
Step-by-step explanation:
Use the distributive property to write an expression that is equivalent to 10a - 15b + 25 in factored form.
Using the distributive property:
10a - 15b + 25
(10a - 10b) - 5b + 25
10(a - b) - 5b + 25
(10(a - b) - 5)b + 25
((10a - 10b) - 5)b + 25

The units and tens digits of one-two digit integer are the tens and units digits of another two- digit integer, respectively. If the product of the two integers is 4930, what is their sum?
Answer:
(10t + u)(10u + t) = 4,930
100tu + 10t^2 + 10u^2 + tu = 4,930
101tu + 10t^2 + 10u^2 = 4,930
10t^2 + (101u)t + (10u^2 - 4,930) = 0
(101u)^2 - 4(10)(10u^2 - 4,930)
= 10,201u^2 - 400u^2 + 197,200
= 9,801u^2 + 197,200
We see that u = 5 gives 442,225.
√442,225 = 665
(10t + 5)(50 + t) = 4,930
500t + 10t^2 + 250 + 5t = 4,930
10t^2 + 505t - 4,680 = 0
2t^2 + 101t - 936 = 0
t = (-101 + √(101^2 - 4(2)(-936)))/(2×2)
= (-101 + √17,689)/4
= (-101 + 133)/4 = 32/4 = 8
So the numbers are 58 and 85.
58 + 85 = 143

Choose 1 answer:
A) Vertical angles
B) Complementary angles
C) Supplementary angles
D) None of the above
Answer:
D) None of the above
Step-by-step explanation:
Let's use process of elimination!
A) Vertical angles are opposite angles formed by two intersecting lines. These two are adjacent, therefore rendering this statement false.
B) Complementary angles are two adjacent angles that add up to 90 degrees. There is no proof that m∠a+∠b=90°, therefore this statement is false.
C) Supplementary angles are two adjacent angles that add up to 180 degrees. Assuming A∈ED, this statement is false as well.
D) None of the answers above are correct.
Hope this helps! :D

What is the area of the trapezoid?
A trapezoid resting on a base. The top side is labeled 14 in. The bottom side is labeled 30 in. The left side is labeled 15 in. The right side is labeled 20 in. Where the left side and the bottom side meet there is a right angle box.
Answer:
29.5 inches squared
Step-by-step explanation:
The formula for the area of a trapezoid is \(\frac{base1 + base2 * height}{2}\),
so base1 = 14 inches and base2 = 30 inches
since there is a right angle, you know that the height must equal the length of the left side, so the height = 15 inches
then, 14+30+15=59 and 59/2=29.5
therefore, your answer would be 29.5 inches squared
Jeff buys two pairs of shoes for $50 each. He can use the following coupons:
Coupon 1: Buy one get one 40% off
Coupon 2: 25% off the entire purchase
Which coupon should Jeff use for the better deal? How much will he save from the original price with this coupon?
Answer:
Jeff should use coupon #2 for a better deal, as he will save $25 with this coupon.
Step-by-step explanation:
First, we need to apply each respective coupon to the same purchase.
Coupon 1:
⭐How do you take 40% off of a number?
let x = the numberx - 0.4xSo if Jeff buys 1 pair of shoes for $50, the 2nd pair of shoes will only cost him 40% off of $50.
Let's calculate what 40% off of $50 is:
\(x - 0.4x =\)
\(50 - 0.4(50) =\)
\(50 - 20 =\)
\(= 30\)
Now, add the cost of 1 pair of shoes ($50) to the cost of 40% off of 1 pair of shoes ($30) to see how much Jeff will have to pay using coupon #1:
50 + 30 = $80
∴ Jeff will pay only $80 when purchasing with Coupon #1.
Coupon #2:
⭐How do you take 25% off of a number?
let y = the numbery - 0.25ySo if Jeff buys 2 pair of shoes for $100 (50*2), the total cost will only be 25% off of $100.
Let's calculate what 25% off of $100 is:
\(y - 0.25y =\)
\(100 - 0.25(100) =\)
\(100 - 25 =\)
\(= 75\)
∴ Jeff will pay only $75 when purchasing with Coupon #2.
75 is less than (<) 80.
Therefore, Coupon #2 gives Jeff a better deal.
If Jeff had bought the two pairs of shoes without any coupons, it would cost him $100.
To find how much Jeff is saving using Coupon #2, subtract how much Jeff spends using Coupon #2 from $100, the original price.
\(savings = 100 - 75\)
\(savings = 25\)
∴ Jeff saves $25 when purchasing with Coupon #2.
Answer: Jeff should use coupon #2 ($25 off)
Step-by-step explanation:
Coupon #1: The first step in figuring out how much money Jeff would save with coupon #1 is by multiplying $50 by 0.40 in order to find out the discount, which is $20. The next step is to subtract the discount from the original price to find out the discounted price, which is $30. However, this is only the price for one of the pairs of shoes. The final step is to add the $30 discounted pair with the $50 undiscounted pair.
This totals to $80.
\((50)(0.40)=20\)
\(50-20=30\)
\(30+50=80\)
Coupon #2: The second coupon follows a very similar process. The first step is to add the two coupons together to find the price of the entire purchase, which is $100. The next step is to multiply the price by 0.25 to find the discount, which is $25. Next, subtract the discount of $25 from the original price to find the discounted price, which is $75.
This totals to $75.
\(50+50=100\)
\((100) (0.25)=25\)
\(100-25=75\)
So, as you can see, the coupon that saves more money is coupon #2.
The amount of money that he will save from the original price is $25
Hope that this helps and is thorough enough!

Please give me a right answer I will give 100 pt and brainliest
Answer:
m = 111.5
j = 35.5
I really hope this is right ;(
Step-by-step explanation:
m = 3j + 5
j + 3j + 5 = 147
4j + 5 = 147
4j = 142
142 ÷ 4 = 35.5
So j = 35.5
3(35.5) + 5 = 111.5
What is the radius of a cylinder if it has a volume of 769.3 cubic meters and a height of 5 meters? (Use 3.14 for π.) 49 m 14 m 7 m 21 m
Answer:
7m
Step-by-step explanation:
v=πr^2h
769.3=3.14*r^2*5
769.3=15.7r^2
769.3/15.7=15.7r^2/15.7
49=r^2
√49=√r^2
√49=r
r=7m
Jun bought 5 gallons of paint. She used 1 gallons for her living room,
1 gallons for her kitchen, and some paint for her dining room. If Jun
hadgallons of paint left over, about how much paint did she use for the
dining room?
Answer:
hope this helps
Step-by-step explanation:
If Jun used 1 gallon for her living room and 1 for kitchen that would be 2/5 gallons. Since you said “gallons” left over after painting the dining room, I would assume used 1 in the dining room (1/5)and had 2 left over.
