Answer:

1. 10

2. 10

3. 12

4. [tex]3\sqrt{14}[/tex] or 11.22497216

Step-by-step explanation:

1. [tex]a^{2}+b^{2} =c^{2}\\\\a^{2} = 8^{2} = 64\\b^{2} = 6^{2} = 36\\c^{2} = a^{2} + b^{2} = 64 + 36 = 100\\c = \sqrt{100} = 10[/tex]

2. [tex]c^{2}-a^{2} =b^{2}\\\\a^{2} = 24^{2} = 576\\c^{2} = 26^{2} = 676\\b^{2} = c^{2} - a^{2} = 676 - 576 = 100\\b = \sqrt{100} = 10[/tex]

3.[tex]c^{2}-a^{2} =b^{2}\\\\a^{2} = 5^{2} = 25\\c^{2} = 13^{2} = 169\\b^{2} = c^{2} - a^{2} = 169 - 25 = 144\\b = \sqrt{144} = 12[/tex]

4. [tex]c^{2}-b^{2}=a^{2}\\\\b^{2} = 11^{2} = 121\\c^{2} = \sqrt{137}^{2} = 137\\a^{2} = c^{2} - b^{2} = 137 - 11 = 126\\a = \sqrt{126} = 3\sqrt{14} = 11.22497216[/tex]

Jamal spends $63.50 on supplies to make some woodworking items. If he sells his items for $7.25 each, how many items does he have to sell to make back his investment and make $50 profit?

Answers

Answer:

16 items

Step-by-step explanation:

He spent $63.50 so he has to earn that back by selling items and also make a $50 profit. So you add $63.50+$50 which is 113.50 and then divide that by $7.25 because that is how much each item he sells costs. Once you do that you get 15.6551 but you can’t sell 15.6551 items so you round up to a whole number which gives you the answer that he has to sell 16 items.

Jamal will have to sell 15.65 items to make back his investment and make profit of $50.

What is ratio?

Ratio basically compares quantities, that means it show value of one quantity with respect to other quantity.

If a and b are two values, their ratio will be a:b,

Given that,

Amount spends by Jamal on woodworking items = $63.50

Also,

Jamal sells each item for $7.25.

Let Jamal sells n items,

To make profit of $50,

Total selling price of woodworking items = 63.50 + 50 = 113.50

To find the number of items, use ratio property,

n x 7.25 = 113.50

n = 113.50/7.25

n = 15.65

Hence, Jamal will sell 15.65 items to make profit of $50.

Each bowling ball weighs 7.3*10^3 grams. The bowling alley has 2.0*10^2 bowling balls. How much do they all weigh, combined? Express your answer in scientific notation.

Answers

Answer:

1.46 x 10⁶g

Step-by-step explanation:

Given parameters:

Weight of each bowling ball = 7.3 x 10³g

Number of balls in the bowling alley = 2.0 x 10²bowling balls

Unknown

The weight of the balls in the alley = ?

Solution:

To find the weight of the balls in the alley, multiply the mass of each balls with the total number of balls;

Weight of the balls = 7.3 x 10³ x 2.0 x 10²

Weight of the balls = (7.3 x 2.0) x 10³⁺²

Weight of the balls = 14.6 x 10⁵g

Therefore, the weight of the balls = 1.46 x 10⁶g

Step-by-step explanation:

Distribute the 2

(2 × x) + (2 × 1)

2x + 2 - 3(x + 5) ≥ 0

Distribute the -3

(-3 × x) + (-3 × 5)

2x + 2 - 3x + (-15) ≥ 0

2x + 2 - 3x - 15 ≥ 0

Combine like terms

2x - 3x + 2 - 15 ≥ 0

-x + (-13) ≥ 0

-x - 13 ≥ 0

+13 +13

-x ≥ 13

Divide both sides by -1 and flip the sign

If n/8 has a remainder of 5, then which of the following has a remainder of 7?

B) n+2/8

C) n+5/8

D) n+7/8

Answers

Answer:

[tex]\frac{n+2}{8}[/tex] has a remainder of 7 ⇒ B

Step-by-step explanation:

In m ÷ n = c + [tex]\frac{r}{n}[/tex] ,

m is the dividendn is the divisorc is the quotientr is the remainderm = (n × c) + r

Let us use the facts above to solve the question

∵ [tex]\frac{n}{8}[/tex] has a remainder of 5

→ Let us find the first number divided by 8 and give a reminder of 5

that means let the quotient = 1

∵ n = (8 × 1) + 5 = 8 + 5

∴ n = 13

∵ [tex]\frac{n+x}{8}[/tex] has a remainder of 7

→ Let us find the first number divided by 8 and give a reminder of 7

that means let the quotient = 1

∵ n + x = (8 × 1) + 7 = 8 + 7

∴ n + x = 15

∵ n = 13

∴ 13 + x = 15

→ Subtract 13 from both sides

∴ 13 -13 + x = 15 - 13

∴ x = 2

∴ [tex]\frac{n+2}{8}[/tex] has a remainder of 7
