Answer:
h=8
Step-by-step explanation:
a²+b²=c²
a=A
b=12
c=13
therefore substitute
A²+(12)²=(13)²
A²=13²-12²
A²=25
A=5
h=3+A
h=3+5
h=8
Answer:
8 ft
Step-by-step explanation:
since it is a right angled triangle and you have 2 side lengths, we use the pythagoras theorem here.
a² + b² = c²
the c² is always your hypotenuse (longest side of the triangle, also opposite to the right angles)
*the b and a doesnt matter which order you put it in*
so; (sub in the numbers to the formula)
a² + 12² = 13²
(rearrange - like terms together)
a² = 13² - 12²
(calculate it)
a² = 25
(simplify it - get rid of the ² on the a)
a = √25
(solve)
a = 5
so, we know that a = 5 and we know that we have an additional 3
5 + 3 = 8

When benny's sister is 24, Benny's age will be 125% of her age. How old will Benny be then, and is Benny is 12 years old now, how old is penny now?
Answers
Answer:
A. 30
B. 6
Step-by-step explanation:
We'll use P for Penny's age and B for Benny's age. When Penny is 24, Benny will be 1.25 her age. Thus:
B = 1.25 * 24
(benny is 25% older than her)
So Benny's age then will be 1.25 * 24 = 30.
When Benny is 30, Penny will be 24. This means that he is older than her by 6 years. Think about it for a second: Benny will always be 6 years older than her. You can write that as:
B = P + 6
If Benny is 12 years old now,
12 = P + 6
Subtract 6 from both sides and you get
6 = P
or P = 6
Penny is 6 years old when Benny is 12.

2(x+8)^(2)+9=29
Answer format: (__,__)
Answers
Answer:
x = {-8 - √10, -8 + √10} exact answer
x = {-11.16, -4.84} decimal approximation
Step-by-step explanation:
2(x + 8)²+ 9 = 29
Subtract 9 from both sides
2(x + 8)² = 20
Divide both sides by 2
(x + 8)² = 10
Take the square root of both sides
x + 8 = ±√10
Subtract 8 from both sides
x = -8 ± √10
x = {-8 - √10, -8 + √10} exact answer
x = {-11.16, -4.84} decimal approximation
x^2- 4x- 12 = 0

The water content of a certain fruit, by weight, is 80%. Therefore, 20% of the
fruit, by weight, is other material.
When left in the sun to dry, the fruit loses 75% of its water content, and the
amount of other material remains the same.
What percent of the dried fruit is water?
Your solution includes the percent water in the dried fruit and an explanation that supports your answer. in other words, how did you find that percent value?
Answers
Answer:
50% is water
Step-by-step explanation:
1. 80% is water and 20% is from other material
2. Lets say a fruit has 100g, to make it easier to understand
2. if the fruit loses 75% of its water, it will lose 75% of 80%, which is 60% of the total weight or 60g lost. The fruit is now 40g
3. If 20% was other material (20g), now other material is 50% (the same 20g)
4. Water is now only 20g, which is 50% of the total weight
Answer:
50% is water I think I am really sorry I I is wrong

Answer:
4: No
5: A
Step-by-step explanation:
4: The mapping does now represent a function. In a function each x value can only have 1 corresponding y value ( meaning that the x values can not repeat.) In the mapping the x value 3 corresponds with 2 y values therefore the mapping is not a function.
5.
Formula for volume of a cylinder = [tex]V=\pi r^2h[/tex]
Where r = radius and h = height
The cylinder shown has a given diameter of 22ft and a given height of 10ft
In order to use the formula we must convert the diameter to radius.
To do this we divide the diameter by 2 ( this is because the radius is equal to half the diameter )
so radius = 22/2 = 11
Now we plug in the dimensions into the formula
[tex]V=\pi 11^210\\11^2=121\\121*10=1210\\1210\pi[/tex]
Remember, it says " Leave your answer in terms of pi," therefore we do not apply pi and leave it as 1210π
We can conclude that the answer is A

An isosceles triangle has an angle that measures 110°. Which other angles could be in that isosceles triangle? Choose all that apply: 110 55 35 15
Answers
Answer:
35 degrees
Step-by-step explanation:
An isosceles triangle has two opposite sides. If the two angles are equal , it means the triangle is an isosceles. Because 90 degrees is greater than 45 degrees, the two sides with the same length, would have a smaller length than the third side
sum of angles in a triangle = 180
180 - 110 = 70
since 2 angles would be equal
70 / 2 = 35
