Find the total surface area of the 3D figure: ft2 9 ft 8 ft 6 ft 8 ft 8 ft

N76 [4]

Answer:

a = 132 ft^2

Step-by-step explanation:

Area of triangle

a = (1/2)bh

---------------------------

Base

a = (1/2)(8)(6)

a = 24 ft^2

----------------------

Each side

a= (1/2)*(8)(9)

a = 36

All three sides

a = 36 * 3

a = 108 ft^2

-----------------------

Total area

a = 24 + 108

a = 132 ft^2

(7y 3 −2y 2 +5) + (4y 3 −3y)

alexira [117]

Answer:

26 y + 5

Step-by-step explanation:

Simplify the following:

7 3 y + 4 3 y - 3 y - 2 2 y + 5

7×3 = 21:

21 y + 4 3 y - 3 y - 2 2 y + 5

-2×2 = -4:

21 y + 4 3 y - 3 y + -4 y + 5

4×3 = 12:

21 y + 12 y - 3 y - 4 y + 5

Grouping like terms, 21 y + 12 y - 3 y - 4 y + 5 = (21 y - 4 y + 12 y - 3 y) + 5:

(21 y - 4 y + 12 y - 3 y) + 5

21 y - 4 y + 12 y - 3 y = 26 y:

Answer: 26 y + 5

Morton made 36 out of 48 free throws last season. What percent of his free throws did Morton make. Help!!! T-T

blondinia [14]

75 % free throws are made by Morton

Solution:

Given that Morton made 36 out of 48 free throws last season

To find: Percent of free throws made by Morton

From given statement,

total number of throws = 48

throws made by morton = 36

Thus the percent of free throws made by Morton is given as:

$percent = \frac{\text{number of throws made}}{\text{total number of throws}} \times 100$

Substituting the values, we get

$percent = \frac{36}{48} \times 100\\\\percent = 0.75 \times 100 = 75 %$

Thus 75 % of his free throws are made by Morton

Simplify the square root (Picture provided)

Elodia [21]

For this case we must find the value of the following expression:

$\sqrt {8 ^ {17}}$

We have to:

$8 ^ {17} = 8 ^ 1 * 8 ^ {16}$

Substituting:

$\sqrt {8 * 8 ^ {16}}$

By definition of properties of powers and roots we have:

$\sqrt [n] {a ^ m} = a ^ {\frac {m} {n}}$

So:

$8 ^ {\frac {16} {2}} * \sqrt {8}\\8 ^ 8 * \sqrt {8}$

So we have to:

$\sqrt {8 ^ {17}} = 8 ^ 8 * \sqrt {8}$

Answer:

$8 ^ 8 * \sqrt {8}$

Option A
