Mary had $25,000 to invest. She invested part of that amount at 3% annual interest and part at 5% annual interest for one year.

emmasim [6.3K]

(25000-f)(.03)+.05f=1100

750-.03f+.05f=1100

750+.02f=1100

.02f=350

f=$17500

So Mary invested $17500 @ 5% and 7500 at 3% to earn $1100 in interest.

If ethans monthly expenses are 1160 and his debt to income ratio is 0.8 what is his monthly salary

lukranit [14]

Answer:

$1450$

Step-by-step explanation:

Based on the given conditions, formulate: $\frac{1160}{0.8}$

Convert decimal to fraction: $\dfrac{1160} {\dfrac{8}{10}}$

Divide a fraction by multiplying its reciprocal: $1160 \times \dfrac{10}{8}$

Cross out the common factor: $145 \times 10$

Calculate the product or quotient: $1450$

get the result: $1450$

Answer: $1450$

Simplified radical form of 4800 feet how many seconds was the diver in a free fall? Using functions (t)=16t^2 models the distanc

amm1812

Answer:

The diver will be in free fall for $10\sqrt{3}$ seconds.

Step-by-step explanation:

The distance in feet, that an object falls in t seconds is given by the function $h(t) = 16t^{2}$ .

Now, given that the height is 4800 feet and we have to calculate the number of seconds the diver was in a free fall.

Therefore, $4800 = 16t^{2}$

⇒ $t^{2} = \frac{4800}{16} = 300$

⇒ $t = \sqrt{300} = \sqrt{100 \times 3} = 10\sqrt{3}$ seconds.

Therefore, the diver will be in free fall for $10\sqrt{3}$ seconds. (Answer)

I have one more Brainliest

Tresset [83]

Okay, so we need to find the price of the original shirt and the discounted shirt with the 5% tax.

5% (into a real number) is .05

Multiply 20.98 and 15.48 by .05

20.98*.05= 1.049 I am going to round to 1.05

15.48*.05= 0.774 I am going to round to .75

Now we know the prices of both, so we subtract them by each other.

20.98+1.05= 22.03
15.48+.75= 16.23

22.03-16.23= 5.80

But since we rounded the numbers, I would go with choice D.

Hope this helps!
