A section in a stained glass window is shaped like a trapezoid. The top base is 2 centimeters and the bottom base is 2.5 centimeters long. If the area of the section of glass is 9.9 square centimeters, how tall is the section?
Answers
Answer:
\(4.4cm\)
Step-by-step explanation:
\(area \\ 9.9 = \frac{1}{2} \times (a + b) \times h \\ 9.9 = \frac{1}{2} \times (2 + 2.5) \times h \\ 9.9 = \frac{1}{2} \times 4.5 \times h \\ 9.9 = \frac{4.5h}{2} \\ 9.9 = 2.25h \\ \frac{9.9}{2.25} = \frac{2.25h}{2.25} \\ h = 4.4 \: \: cm\)

Answers
Answer:
A
Step-by-step explanation:
We can solve for H by isolating it on one side of the equation, as follows:
J/H - I/H = G
Taking H as the common denominator:
(J - I)/H = G
Multiplying both sides by H:
J - I = GH
Adding I to both sides:
J = GH + I
Dividing both sides by G:
H = (J - I)/G
So the answer is
(A)
H = (J - I)/G.
Answer: A
Step-by-step explanation:
\(\frac{J}{H} = G + \frac{I}{H}\) >Since you are solving for H bring I/H to the other side
by subtracting I/H from both sides
\(\frac{J}{H}- \frac{I}{H} = G\) >There is a common denominator so you can
combine the fractions
\(\frac{J-I}{H} = G\) >Multiply both sides by H or cross multiply whichever
way your mind things about how to get H on top
\(J-I = G(H)\) >Divide both sides by G
\(\frac{J-I}{G} = H\) >Answer is A

Answers
Answer:
D is the right choice and no you cannot fit the pizza inside the box.
Step-by-step explanation:
D is the answer because to turn 2/3 into a decimal you would divide 2 by 3 and the answer you would get would be 0.66666666666...You would then add 12 to the answer and get 12.6666... Once you get this answer you would round it to the hundredths to get 12.67 but since that is not an option you could use D, 12.66 inches.

William is a very busy professional DJ. Last year, he worked at 10-anniversary parties and 26 other events.
What is the probability that one of the events William worked on last year, selected at random, was an anniversary party?
Write your answer as a fraction or whole number.
Answers
Answer:
hello
Step-by-step explanation:
The required probability that William worked on last year was an anniversary party is 1/ 36.
As mentioned in the quesiton,
William is a very busy professional DJ. Last year, he worked at 10-anniversary parties and 26 other events.
Probability can be defined as the ratio of favorable outcomes to the total number of events.
Here,
Total sample space = 26 + 10 = 36
Number of favorable outcomes = 1
the probability that William worked on last year is was an anniversary party,
= Favorable outcome/sample space
= 1 / 36
Thus, the required probability that William worked last year is 1/ 36.

angles A and B are complementary angles. if the measure of Angle A= (7x+25), and the measure of Angle B is (x+9), then find the measure of Angle A
Answers
X = 6.5
To find the measure of an angle line the protractor and read what the number says
Answer:
74 degrees
Step-by-step explanation:
We first need to know what complementary angles are. Complementary angles are 2 angles that the sum is 90 degrees. We can write an equation:
(7x+25)+(x+9)=90
combine like terms
8x+34=90
subtract 34 from both sides
8x=56
divide both sides by 8
x=7
The next step, now that we have x=7, we need to find the measure of Angle A.
7x+25
substitute
7(7)+25
=74
So, Angle A is 74 degrees.

The two plots below show the heights of some sixth graders and some seventh graders:
Two dot plots are shown one below the other. The title for the top dot plot is Sixth Graders and the title for the bottom plot is Seventh Graders.

(solve, show work) Jennifer earns $1,920 in interest after making a deposit 6 months ago at a rate of 12.5%. What was the initial deposit 6 months ago? PLS answer this seriously its really important tysm!
Answers
Answer:
P = $1807.058
Step-by-step explanation:
Given
A=$1, 920
R=12.5% =12.5/100
T= 6month = 6/12 .... to change to year
Required
p=?
Solution
A= I + P ......... I= PRT
A = PRT + P
A= P(RT+1)
$1920 = P( 12.5/100 ( 6/12) + 1 )
$1920= P(1.0625)
P = $ 1920 / 1.0625
P = $1807.058
We can use the simple interest formula to solve this problem. The formula is:
I = P*r*t
where I is the interest earned, P is the principal (initial deposit), r is the annual interest rate, and t is the time in years.
First, we need to convert the annual interest rate of 12.5% to a monthly rate. We can do this by dividing the annual rate by 12 (the number of months in a year):
r = 12.5%/12 = 0.01041667
Next, we need to convert the time of 6 months to a fraction of a year. We can do this by dividing 6 by 12:
t = 6/12 = 0.5
Now we can plug in the given values and solve for P:
I = P*r*t
$1,920 = P*0.01041667*0.5
$1,920 = P*0.00520833
P = $1,920/0.00520833
P = $368,640
Therefore, the initial deposit 6 months ago was $368,640.

so Y = 1/3x + 2

Now, we shall use points (3,2) as the substitutes for the solution for b, which 3 would be the input and 2 would be y.
Therefore, 2 = 1/3(3) + b
2 = 1 + b, therefore, one would be subtracted from 2 which would give us the answer of b equaling to one. Thus, y = 1/3x + 1

the ratio of the number of oranges to apples to bananas is 8:5:2. if there are 120 fruits in total, how many bananas are there
Answers
Answer:
Step-by-step explanation:
To find the number of bananas, we need to determine the proportion of bananas in the total number of fruits based on the given ratio.
Let's assume that the ratio of oranges, apples, and bananas can be represented by 8x, 5x, and 2x, respectively, where x is a common multiplier.
The sum of the parts in the ratio is 8x + 5x + 2x = 15x.
We know that the total number of fruits is 120. Therefore, we can set up the following equation:
15x = 120
To solve for x, we divide both sides of the equation by 15:
x = 120 / 15
x = 8
Now that we know the value of x, we can find the number of bananas by multiplying it by the corresponding part of the ratio:
Number of bananas = 2x = 2 * 8 = 16
So, there are 16 bananas in total.
We can add all the parts to the ratio and get 15. Out of 15 parts, 2 are bananas. Now we can calculate how many fruits are in one part. One fifteenth of 120 is 8, so there are 8 fruits in one part. 2 parts are bananas, so multiplying 8 with 2 gives us our answer, 16.

y= 1/2x + 1
Step-by-step explanation:
Refer to y=mx+b, m=slope and b= y-intercept
First, you find the slope: you can find the slope by finding the rise over run between two points. Rise= 1, Run=2. The slope is rise/run (rise over run), so the slope would be 1/2 (one half).
Next, find the y-intercept. It is where the line touches the y-axis. Here, it would be 1.
Finally, put these in y=mx+b form:
y=(slope)x+(y-intercept) ---> y= 1/2x + 1
