Answer:

$370

Step-by-step explanation:

You already have 90 dollars so we can put that to the side for right now

If you're charged $35 at an hourly rate for 8 hours then you have to multiply the two together

30 x 8 = 240

5 x 8=40

240 + 40=280

Now is when your $90 dollars comes in. Now just add the two together and you'll end up with your final answer

280+90=370

Jessica decided to use 15% of her gross income for her down payment for a house. She makes 48,960.00 per year. How much money di
babymother [125]

Answer:

Down\ payment = 7,344

Step-by-step explanation:

Let x be the amount of 15% of gross income.

Given:

Jessica gross income = 48,960.00

She decided to use 15% amount as down payment.

We need to find the amount of 15% of gross income.

Solution:

Using percentage formula.

percentage = (\frac{Value}{Total\ value})\times 100

Now we substitute 15 in the place of percentage and 48,960 in the place of Total value.

15=(\frac{x}{48960})\times 100

Now, we apply cross multiplication rule.

x= \frac{48960\times 15}{100}

x=48960\times 0.15

x =7,344

Therefore: Down payment is 7,344.

vovangra [49]
You need 4 days to get the 44 grams of protein you need. This is because 44 divided by 12 is about 3.6666 which would round up to 4 because you can't don't less than a full day

Please help me solve this !!
mixas84 [53]

Answer:

B) 6.68

Step-by-step explanation:

Use Cosine.

Cosine= Adjacent ÷ Hypotenuse

In this case the base you want to find is adjacent to the angle, 42°. Hence,

Cos (42)= adjacent ÷ hypotenuse

Cos (42) = x ÷ 9

x = Cos (42) × 9. Input that into your calculator.

x= 6.68

To remember the trigonometric ratios/formulas

Use the acronym, SOHCAHTOA

Hope this helps!!!!
