If ∠C and ∠D are complementary angles, m∠C = (4x + 3)°, and m∠D = (15x – 8)°, find m∠D
Answers
Answer:
52
Step-by-step explanation:
complementary angles meaning sum of both angles is 90
so equations is
(4x + 3) + (15x – 8) = 90
x=5
insert x into angle d equation
d=15(5)-8
d=60-8
d=52
Answer:
<D = 67 degrees

a bottle contains 24.5 oz of water. a leak in the bottle causes it to lose 0.3 oz of water every minute. how many minutes does it take for the bottle to lose 33% of the water?
Answers
Answer 54.7 Minutes
Step-by-step explanation:
33% × 24.5 =
(33 ÷ 100) × 24.5 =
(33 × 24.5) ÷ 100 =
808.5 ÷ 100 =
8.085 ≈
8.09;
so then 8.09 - 24.5 = 16.41
16.41 divided by 0.3 = 54.7
54.7 minutes it take for the bottle to lose 33% of the water.
What is Percentage?The percentage formula is used to calculate the amount or percentage of anything in terms of 100. Percentage indicates "per hundred" in its most basic form. The percentage formula is used to express a number between zero and one. It is a number that is expressed as a fraction of 100. It is represented by the sign% and is mostly used to compare and find ratios.
We have a bottle contains 24.5 oz of water.
A leak in the bottle causes it to lose 0.3 oz of water every minute.
So, 33% × 24.5
= (33 ÷ 100) × 24.5
= (33 × 24.5) ÷ 100
= 808.5 ÷ 100
= 8.085
= 8.09
So, the amount water loses
= 24.5 - 8.09
= 16.41 oz
Now, the amount of time for bottle to loose 33% of water
= 16.41 / 0.3
= 54.7 minutes

A rectangle has its diagonal length increased from 5 cm to 25 cm. The new rectangle is similar to the original one. The original perimeter was 14 cm. What is the measure of the new perimeter?
Answers
Answer:
The measure of the new perimeter is 70cm.
Step-by-step explanation:
I thought putting up a picture would be easier than explaining it all. The picture is how you would write out the problem.
The original rectangle's measures were 5cm and 14cm. The new rectangles measures are 25 cm and X (We don't know yet.) So write it out. 5cm is to 14cm as 25cm is to X.
5cm/14cm = 25cm/X
Cross multiply. (The arrows I drew. Multiply diagonally.)
You should get
350 = 5X
We need to get X by itself, so divide both sides by 5.
5X/5 leaves X left
350/5 leaves 70
70 = X

CFMS has contacted a band to play at an upcoming event. The band will charge a travel fee of $525 plus $12.50 per ticket sold.The school decides to turn the event into a fundraiser by increasing the cost of the tickets. If they want to make a profit of $875, how much will they need to charge per ticket?
Answers
Answer:
x=28 so they need to charge 28 tickets
Step-by-step explanation:
525 + 12.50x=875
First, take the 525 and drag it to the other side which will become into negative so the equation will be 12.50x=875-525 now just subtract it and u will get the answer of 12.50x=350 now all you need to do is divide [tex]\frac{350}{12.5}[/tex] and now the answer will be x=28 to double check we can just multiply 12.5 times 28 = 350 now plus 525 is = to 875 hope this helped :>

A fraction is a way to describe a part of a whole. The given fractions can be arranged as shown below.
What is a Fraction?A fraction is a way to describe a part of a whole. such as the fraction ¼ can be described as 0.25.
In order to put the following fractions in order from least to greatest, we need to take the LCM of the fraction so that all the fractions have the same denominator.
1/8, 2/5, 3/5, 1/6, 1/4, 2/3, 1/3
Since the LCM of 3, 4, 5, 6, and 8 is 120. Therefore, the fractions can be written as,
1/8 = (1/8) × (15/15) = 15/120
2/5 = (2/5) × (24/24) = 48/120
3/5 = (3/5) × (24/24) = 72/120
1/4 = (1/4) × (30/30) = 30/120
2/3 = (2/3) × (40/40) = 80/120
1/3 = (1/3) × (40/40) = 40/120
Now, the fractions can be arranged as,
15/120 < 30/120 < 40/120 < 48/120 < 72/120 < 80/120
Rewriting the fraction in there original form,
