Answer:

4.9 units

Step-by-step explanation:

We are dealing with a Right angle triangle, and the c is actually the hypotenuse. We are given the measures of a and b.

a being 4, and b being 3.

We need to use the Pythagorean Theorem to solve this.

a^2 + b^2 = c^2

we can rewrite this as;

4^2 + 3^2 = c^2\\

Calculation time

15 + 9 = c

c = 24

Now we find the square root of each equation to determine what c^2 is.

\sqrt{15}+\sqrt{9}=\sqrt{24}

4 + 3 = 4.89897948557

Let's round that to the nearest tenth.

4.9 units

Hope this helped :)

anna owes home antiques Whose value is 160000 today assuming normal growth. however anna believes the value will grow at 16% per
Ray Of Light [21]
The formula is
A=p (1+r)^t
A future value?
P present value 160000
R interest rate 0.16
T time 3years
A=160,000×(1+0.16)^(3)
A=249,743.36

Use that future value to find the present value at a rate 8% compounded annually
To find p (present value) solve the formula for p
P=A÷ (1+r)^t
Where r is 0.08
P=249,743.36÷(1+0.08)^(3)
p=198,254.33

Find the height of a triangle with area = 110 ft squared and base = 10ft
maria [59]
Well to find the are of a triangle is like finding the are of a rectangle but in half so multiply 110 by 2 to get the original answer before it was divided by 2:

110×2=220

now we need to find out how many 10 are in 220:

220÷10=22

so the height of the triangle would be 22 ft

hope this helped

Answer:

Blanks top to bottom: 6^2, 36, 9, 108, 101

Step-by-step explanation:

Use PEMDAS which stands for parentheses, exponents, multiplication, division, addition, and subtraction. Listed in this specific order, you must look and solve for each one first, starting with parentheses.

4.

12 × ((4+2)^2/4) - 7

Solve for inside of parentheses first:

12 × ((6)^2/4) - 7

12 × (36/4) - 7

12 × 9 - 7

108 - 7

101
