Answer:
x = 17
Step-by-step explanation:
The angles 3x + 1 and 4 + 2x MUST total 90 degrees:
5x + 5 = 90 degrees
or: 5x = 85 degrees
therefore: x = 17
Answer:
x=17
Step-by-step explanation:
(3x+1)+(4+2x)=90
3x+1+4+2x=90
5x+5=90
5x + 5 - 5 = 90 - 5
5x = 85
5x/5 = 85/5
x = 17

The actual gallery comes to be 84 feet long.
What is a scale factor?A scale factor is a factor by which the dimension of an object is enlarged or diminished.
Scale of 2 inches = 7feet.
So, a scale of 1 inch = 7/2 feet
So, scale factor =7/2
So, a scale of 24 inches = 24*scale factor= 24*7/2 = 84 feet
So, the actual length of the gallery = 84 feet

Answer:
To determine its end behavior, look at the leading term of the polynomial function. Because the power of the leading term is the highest, that term will grow significantly faster than the other terms as x gets very large or very small, so its behavior will dominate the graph.

An investor has an account with stock from two different companies. Last year, his stock in Company A was worth $3800 and his stock in Company B was worth $3400. The stock in Company A has decreased 22% since last year and the stock in Company B has decreased 12%. What was the total percentage decrease in the investor's stock account? Round your answer to the nearest tenth (if necessary).
Answers
Answer: The total percentage decrease in the investor's stock account is 34%
Step-by-step explanation:
The investor's stock in Company A= $3800
The investor's stock in Company B= $3400
Percentage decline in stock of company A= 22%
Decline in value of stock of company A= 3800× 22/100
= 38×22
= $836
Percentage decline in stock of company B= 3400×12/100
= 34×12
=$408
Total decline in wealth of investor= 836+ 408
= $1244
Total percentage decline in wealth= 1244×100/7200
= 124400/7200
= 17.27%
The percentage decrease in investor's stock is 17.27%

Today, after 10 days, the bean plant is 27 inches tall. How tall was it yesterday?
Answers
Answer:
23.48 inches
Step-by-step explanation:
Knowing that the plant grows 15% of its height every day, 27 inches would represent 115% of its height from the day before.

Answers
Answer:
see explanation
Step-by-step explanation:
Sum their ages , 11 + 19 + 20 = 50
Divide £500 by 50 to find the value of one part of the ratio
£500 ÷ 50 = £10, thus
11 × £10 = £110 ← Pete's share
19 × £10 = £190 ← Fred's share
20 × £10 = £200 ← Sarah's share
Answer:
Pete's share: £110
Fred's share: £190
Sarah's share: £200
Step-by-step explanation:
Add their ages:
11 + 19 + 20 = 50
500 ÷ 50 = £10
Then you times their age with £10 to get how much they all get.
10 x 11 = £110
19 x 10 = £190
20 x 10 = £200

x = 1.5 ft.
Step-by-step explanation:
This is a right triangle, of course, so the Pythagorean Theorem applies.
Looking at this figure, I can see that the hypotenuse is 3.9 feet and one of the legs is 3.6 and feet.
The only side length missing is the second leg.
Here, I am solving for the second leg.
\(a^2+b^2=c^2\)
\(3.6^2+x^2=3.9^2\)
\(12.96 + x^2=15.21\)
\(15.21-12.96=2.25\)
\(x^2=2.25\)
\(x=1.5\)
Therefore, the length of the missing side is 1.5 ft.

The histogram shows the number of points scored by a basketball team for one season. A histogram titled points scored in one season shows the number of games in which a certain number of points were scored. The data is as follows. 69 to 76 points: 3 games. 77 to 84 points: 6 games. 85 to 92 points: 8 games. 93 to 100 points: 1 game. According to the histogram, in what percentage of games did the team score between 77 and 92 points? Enter your answer in the box. Round your answer to the nearest percent.
Answers
Find the total number of games with points scored between 77 & 92 pts - 14
To find the percentage divide 14/18 - .777
Multiply .777*100 - 77.7
Round to 78%
Percentage of games the team scored between 77 and 92 is 77.7% .
Given data from the histogram shows the number of games that are played in the range of 77 - 92.
Total number of games played = 18
Number of games played in the range 77 - 92 = 14
Percentage of games played in the range 77-92 = (Number of games played in the range 77 - 92) / (Total number of games played) × 100
Percentage = (14)/(18) × 100
= 77.7% .
Hence the number of games played in the given range is 77.7%.
