Answer:
40ft^2
Step-by-step explanation:
Hello There!
In this problem since we know that these are similar triangles we can set up a ratio in order to solve for the missing leg lenght, and then the areas.
This can be done by using the ratios and solving for x:
[tex]\frac{8ft}{12ft}[/tex] x [tex]\frac{4ft}{x}[/tex]
After this is done we find that the missing leg on the larger triangle is equal to roughly 6. With this in mind we find the area of the two triangles by multiplying the legs and dividing by 2, respectively.
The larger triangle will have an area of 72ft^2
the smaller triangle will have an area of 32ft^2
in order to find the difference in area we will simply subtract the two and find that the difference is equal to 40ft^2
Hope this helps

30% of x = 12
Answers
30% = 0.30
0.30x = 12
Divide both sides by 0.30
X = 12/0.30
X = 40
Answer:
x=40
Step-by-step explanation:
30% is the same as 3/10.
-So now you have 3/10 of x = 12.
The term “of” in the equation is the same as multiplication.
-So now you have 3/10 · x = 12 (the dot is multiplication)
Multiply both sides by the reciprocal of 3/10, which is 10/3
-So now you have x=120/3, which is equal to x=40 (that’s you answer)
You can check your answer by plugging in 40 for x.
30% of 40 is indeed equal to 12.
Hope this helps and answers your question :)

Given:
The figure.
To find:
The theorems that proves triangles SRP and QRP are congruent.
Solution:
From the given figure, it is clear that in triangle SRP and QRP,
Hypotenuse of triangles : [tex]PS=PQ[/tex] (Given)
Legs of triangles : [tex]SR=QR[/tex] (Given)
Since, hypotenuse and one leg of first triangle is equal to the hypotenuse and corresponding leg of another triangle, therefore, both triangles are congruent by HL postulate of congruence.
[tex]\Delta SRP\cong \Delta QRP[/tex] (HL postulate of congruence)
Therefore, the correct option is E .

Monthly gross pay = $7650.68
Annual gross pay = $91808.16
Explanation:
To get the monthly gross pay, you double the semi-monthly gross pay. In other words, you multiply by 2.
Once you know how much you earn per month, you multiply that by 12 to get your annual pay.
The term "gross" in financial terms means the amount of money before taxes and other fees apply. The net pay is after taxes and other fees are deducted from your paycheck. This means the net pay is going to be smaller than the gross pay.

y=-2x-6
y=2x+6
y=-2x+2
y=2x+2
Plz answer quick!!!!
Answers
Answer:
y = 2x + 2
Step-by-step explanation:
The formula is y = mx + b, and to find the slope it's y2-y1 / x2-x1, so you do 4-16 = -12 and 1-7 = -6, and -12/-6 = , so your slope is 2.
Then you use one point and put it into your equation ex: 4 = 2(1) + b and simplify to find the y-intercept (b).
Then that's your answer!

1. In a supermarket, each orange costs $3, and each apple costs $2. If you want to spend
exactly $45, write an equation in standard form modeling this situation. Let o represent
the number of oranges you buy, and a represent the number of apples you buy.
Answers
Answer:
3o + 2a = $45 ( you can buy 9 oranges and 9 apples)
Step-by-step explanation:
First I divided 45 by 3 and I got 15 so now I know that 15 is the highest amount of oranges I can buy without going over $45. I also know that 15 cannot be an answer because I also have to buy apples.
Then I divided 45 by 2 and 22 was the highest whole number.
Now I would play trial and error BUT i know that the number for oranges have to be less that 15 and the number for apples has to be less than 22.
3 times 9 equals 27 (oranges)
45 - 27 = 18
2 times 9 equals 18 (apples)
3o+2a =$45 is the equation in standard form modeling this situation.
What is Equation?Two or more expressions with an Equal sign is called as Equation.
Given that in a supermarket, each orange costs $3, and each apple costs $2.

Answers
We have been given that adult male heights are normally distributed with a mean of 70 inches and a standard deviation of 3 inches. The average basketball player is 79 inches tall.
We need to find the area of normal curve above the raw score 79.
First of all let us find the z-score corresponding to our given raw score.
, where,
,
,
,
.
Upon substituting our given values in z-score formula we will get,
Now we will find the P(z>3) using formula:
Using normal distribution table we will get,
Let us convert our answer into percentage by multiplying 0.00135 by 100.
Therefore, approximately 0.135% of the adult male population is taller than the average basketball player and option A is the correct choice.

Answers
I will do number 1 only. You can then use my solution steps to do the rest.
Solve 4x + 5 > 5x − 2 for x.
4x + 5 > 5x − 2
4x - 5x > - 2 - 5
-x > -7
Dividing both sides by a negative number reverses the inequality sign. In other words, the sign > becomes < in the reply.
-x/-1 < -7/-1
x < 7
Answer: x < 7
The answer here means that whatever the value of x is for question 1, it must be less than 7.
You finish.
