(7 - 1) to the 2 power plus 2 and to the 4 power - 8

Answers

Answer 1

The answer is 56. work is shown below.

Step 1: apply 2nd power to everything inside parentheses

(7 - 1)² = 7² - 1²

Step 2: apply exponents (remember, exponents are a shorter way to express a number multiplied by itself a number of times).

1 x 1 = 1

7 x 7 = 49

Step 3: subtract

49 - 1 = 48

Step 4: apply exponent

2 x 2 x 2 x 2 = (2 x 2) x (2 x 2)

2 x 2 = 4

4 x 4 = 16

2⁴ = 16

Step 5: add

48 + 16 = 64

Step 6 (final step): subtract

64 - 8 = 56

final answer: 56

Answer:

total: 2.85 hours = 2 17/20 hours

Step-by-step explanation:

Strategy: convert all fractions to decimals, determine weeding and mowing times, and add the three times to find the total.

3/4 = 0.75

1/5 = 0.2

Solution:

raking time: 0.75 hours

weeding time: 0.75 +0.2 = 0.95 hours

mowing time: 0.95 +0.2 = 1.15 hours

Total time: 0.75 +0.95 +1.15 = 2.85 hours = 2 17/20 hours

_____

Additional comment

You may recognize that 0.95 is the middle of three equally-spaced values. Then the total will be 3×0.95 = 2.85 hours.

2. The subsets of {a,b,c} are

{ } (emptyset}, {a}, {b}, {c}, {a,b}, {a,c}, {b,c}, {a,b,c}

A student's cost for last semester at her community college was $2800. She spent $308 of that on books. What percent of last semester's college costs was spent on
books?
% of last semester's college costs was spent on books.

Answers

You want to divide the cost of the books by the total costs.

308/2800 = 0.11

You then need to convert 0.11 to a percent: 0.11 = 11%

Therefore, 11% of her costs last semester were spent on books.

Solve for x and find the value of the unknown angle measures.
1. x=
2. m=
3. n=
4. p=

Answers

Answer:

x=20°

m=50°

n=68°

p=50°

Step-by-step explanation:

Here,we know that,

i)n=68°[being vertically opposite angle]

ii)p+62°+n=180°[being straight angle]

or, p+62°+68°=180°

or, p+130°=180°

or, p=180°-130°

thus, p=50°

iii) m=p[being vertically opposite angle]

thus, m=50°

iv)(2+3x)°=62°[being vertically opposite angle]

or, 3x°=62°-2°

or, 3x°=60°

or, x=60°÷3°

thus, x=20°

Hence, the value of x=20°, m=50°, n=68° and p=50°.

Step-by-step explanation:

7(x+1)=1-2(5-x)

7x+7=1-10+2x

7x-2x=1-10-7

5x = -16

x = -16/5

Answer: [tex]\huge {x = -\frac{16}{5} }[/tex]

Step-by-step explanation:

Given equation

7 (x + 1) = 1 - 2 (5 - x)

Expand parentheses and apply the distributive property

7x + 7 = 1 - 10 + 2x

Combine like terms

7x + 7 = -9 + 2x

Subtract 2x on both sides

7x + 7 - 2x = -9 + 2x - 2x

5x + 7 = -9

Subtract 7 on both sides

5x + 7 - 7 = -9 - 7

5x = -16

Divide 5 on both sides

5x / 5 = -16 / 5

[tex]\boxed{x=-\frac{16}{5} }[/tex]
