A health insurance payment of $34.55 was deducted from ms. Donaldson's earnings for the week. After the insurance deduction, payroll taxes equal to 28% of the balance were deducted. What was the amount that Ms. Donaldson received?

Answers

I think that this quesion is missing some background, that is that Ms. Donaldson earned 907.10

So the 34.55 were deduced from this number, and the remaining amount was:

907.10-34.55=872.65

After this, further 28% were deduced, which means that 100-28=72% were left.

And this is:72%*872.55= 628.236 (which we round to 628.24!)

Answer: the answer would be 628.24!

You are building a scale model of a fishing boat. The boat is 62 ft long and 23 ft wide. Themodel will be 14 in long How wide should it be?

Answers

The wide of the model should be approximately 5.194 inches

Step-by-step explanation:

You are building a scale model of a fishing boat

The boat is 62 ft long
The boat is 23 ft wide
The model will be 14 in long

We need to find how wide should it be

∵ The boat is 62 feet long

∵ The model of the boat is 14 inches long

- That means 14 inches represents 62 feet

By using the ratio method

→ Actual (ft) : Model (in)

→ 62 : 14

→ 23 : x

By using cross multiplication

∵ 62 × x = 23 × 14

∴ 62 x = 322

- Divide both sides by 62 to find x

∴ x ≅ 5.194

∵ x represents the wide of the model

∴ The wide of the model is approximately 5.194 inches

The wide of the model should be approximately 5.194 inches

What are the solutions of the equation x4+6x^2+5=0? Use substitution to solve

Answers

Answer:

+ or - square root of 5, and + or - i

Step-by-step explanation:

(x^2 + 5)(x^2 + 1)= 0

Set each set of parentheses equal to zero:

x^2 + 5 = 0; x^2 = -5, so x will equal plus or minus i times the square root of 5.

X^2 +1 = 0; x^2 = -1, so x will equal plus or minus i times the square root of one, which is just i

Answer: The solutions are i and 5i.

Step-by-step explanation:

Since we have given that

$x^4+6x^2+5=0$

By using Substitution, we use

$y=x^2$ in the above equation:

$y^2+6y+5=0\n\ny^2+5y+y+5=0\n\ny(y+5)+1(y+5)=0\n\n(y+1)(y+5)=0\n\ny=-1,-5$

Now, put the value of y in the equation $y=x^2$ .

Put y = -1,

$-1=x^2\n\nx=√(-1)=i$

Similarly, put y = -5

$-5=x^2\n\nx=√(-5)=5i$

Hence, the solutions are i and 5i.

10) 1 gallon of water for every inch of the fish's body length.
a) 2 1/2 inches long fish needs 2 1/2 gallon of water.
b) tank: l = 7 inches ; w = 5 inches; h = 7 ; volume = 7in * 5in * 7in = 245 in³
c) no. her fish tank is not large enough for the fish.
volume of 1 gallon of water is 231 in³, water needed is 2 1/2 gallon, so 5/2 * 231 in³ = 577.50 in³ volume.

11) volume = 7in * 3.5in * 1.75 in = 42.875 in³
weight of the brick = 0.1 pound per cubic inch ⇒ 42.875 in³ * 0.1 lb = 4.2875 pounds
weight of the gold bar = 0.7 pound per cubic inch ⇒ 42.875 in³ * 0.7 lb = 30.0125 pounds

12) l = 55cm ; w = 40cm ; h = 30 cm
volume = 55cm * 40cm * 30cm = 66,000 cm³
