Two triangles have the same height. The base of one
triangle is twice that of the other. Find the difference in
their areas.
[tex]\huge\underline{\overline{\mid{\bold{\red{ANSWER}}\mid}}}[/tex]
They both have same height,
let the height of both triangles be = x
let the base one triangle = y
then the base of another trainlgle = 2y
Area of triangle = 1/2 X B X H
Area of Triangle 1
[tex] \frac{1}{2} \times y \times x \\ = > \frac{xy}{2} [/tex]
Area of Triangle 2
[tex] \frac{1}{2} \times 2y \times x \\ = > \frac{2xy}{2} \\ = > xy[/tex]
Difference in the area =
[tex]xy - \frac{xy}{2} \\ = > \frac{2xy - xy}{2} \\ = > \frac{xy}{2} [/tex]
Hence Area of Triangle 1 is half the area of Triangle 2
Difference of 1/2 area.

15% tip on a bill of $51.03
Answer:
7.6545
Step-by-step explanation:
Alana makes and sells homemade bracelets. She made a profit of $65 last week. This week, she donated some bracelets to charity. Her profit at the end of this week can be represented by -$25. Write a subtraction expression and an addition expression to represent Alana’s total profit for two weeks combined.
Answer:
$65 + $(-25) = $40
$65 - $25 = $40
Step-by-step explanation:
Profit made last week = $65
Profit made this week = - $25
Addition expression for her profit over the two weeks
Last week profit + this week's profit:
$65 + $(-25) = $40
Subtraction expression for her profit over the two weeks :
$65 - $25 = $40
Zach needs a new pair of running shoes.The pair that he wants regularly sells for $129.If they are on sale for 24% off,how much will he pay in total if sales tax is 6.4%?
Answer:
$104.31
Step-by-step explanation:
First let's calculate the sale price of the shoes. If they are 24% off, that means they will be worth 76% of the initial price. So, we can multiply 76% by 129 to find the sale price:
129 * 0.76 = 98.04
The sale price is $98.04. To find the value of the sales tax, multiply the sale price by the percentage of the sales tax:
98.04 * 0.064 = 6.27456
The sales tax rounds to 6.27. Finally, to find the total price, add the value of the sales tax to the sale price:
98.04 + 6.27 = 104.31
The total price Zach will pay is $104.31.

Answer: [tex]\frac{6}{2}[/tex]
Step-by-step explanation:
1. Use this [tex]\frac{f(b)-f(a)}{b-a}[/tex] to find the average rate of change
2. Average rate of change = [tex]\frac{f(8)-f(6)}{8-6}[/tex]
3. [tex]f(8) = - 4[/tex] and [tex]f(6) = -10[/tex] (To find these you will need to look at the points on the graph. So the points (8,-4) and (6,-10))
4. Replace -4 to f(8) and -10 to f(6)
5. So it will look like[tex]\frac{-4-(-10)}{8-6}[/tex]
6. Solve [tex]\frac{6}{2}[/tex]

Sophie buys x packages of graph paper for $2.55 each (tax included). She pays with a $20 bill.
Write an algebraic expression to represent the amount of change the cashier should give back to Sophie.
Answer:
x=$20/$2.55.
Step-by-step explanation:
if each package is $2.55 then and it cost $20 then you will have to divide the numbers wich will give u x
Answer:
20 - 2.55x
Step-by-step explanation:
20 is the dollar bill Sophie bought the packages with, x represents the number of packages bought and 2.55 is the price for each, so by subtracting 20 by the cost of the total packages results in the amount of change the cashier should give back to Sophie.
For example, if Sophie bought 3 packages of graph paper with a $20 bill the cashier should give back to Sophie $12.35.
20 - 2.55 (3)
20 - 7.65
12.35

12. The probability a basketball player making a free-throw
is .84, what are the odds against making a free-throw?
Answer:
The odds against making a free throw are: 0.1905 or 0.16:0.84
Step-by-step explanation:
The odds can be categorized into two categories
Odds-againstOdds-in favourThe odds against is the ratio of probability of failure to probability of success.
Given
Probability of making a free throw = P = 0.84
Probability of not making a free throw = Q = 1-P = 1-0.84 = 0.16
The formula for odds-against is:
[tex]Odds-against = \frac{0.16}{0.84}\\= 0.19047..\\=0.1905[/tex]
Hence,
The odds against making a free throw are: 0.1905 or 0.16:0.84
Sandra worked 6 hours on Wednesday, 5 hours on Thursday, and 4 hours on Friday. What is the mean number of hours she worked over the three-day period? A 2 h B 3 h C 4 h D 5 h
Answer:
The mean should be D. 5
Step-by-step explanation:
The mean means the average which in this order (4, 5, 6) The direct middle is 5, making it the average since there are only 3 numbers in the first place.
You can mark out A (2) and B (3) instantly because they are lower than any of beginning numbers, and it's not C (4) as 'mean' doesn not mean the lowest, which leaves you with D (5)

Answer:
bottom right is correct
Step-by-step explanation:
You decide to join a tennis class. The initial entrance fee is
$100, and a $10 fee every month you want to take the class.
How much will it cost for five months?
Given :
Initial entrance fee of tennis class, E = $100 .
Fee of every month, F = $10 .
To Find :
How much will it cost for five months.
Solution :
Let, number of months are n and cost of class is y.
So, linear equation is given by :
y = 10n + 100 ...1)
To know the cost of 5 month, putting value of n = 5 in equation 1) we get :
y = ( 10×5) + 100
y = 50 + 100
y = $150
Therefore, the cost of five month fee in tennis class is $150.
Hence, this is the required solution.
100 middle school students take a survey that asked them About there fruit Preferences 37 out of 100 students said they prefer pineapple to peaches how would you write this amount as a percentage
Answer:
37%
Step-by-step explanation:
First, we need to know that 1 student equals 1 percent.
If 37 students chose pineapple, than it would be 37%
(Some times, you have lets say... 75 students, so you would do 75, subtracted from 74 (Or one less), to get how much one student is.)
