Answer:

It is A

Step-by-step explanation:

Because in general, 'to bisect' something means to cut it into two equal parts. The 'bisector' is the thing doing the cutting. With a perpendicular bisector, the bisector always crosses the line segment at right angles.

Troy is buying a car that costs $15,000. He plans to get a 5-year loan to pay for it. He can get a loan for $15,000 or he can pa

Answer:

a) $300

b) $75

Step-by-step explanation:

Cost of the Car = $15,000

a) Rate of interest received on savings(r) = 2%

Amount in savings account(p) =$3000

Time period(t) = 5 years

Simple interest = $\frac{P \times R \times t}{100}$

= $\frac{3000 \times 2 \times 5}{100}$

= $300

Interest received on savings account = $300

b) Rate of interest on loan = 0.5%

IF P= 15000

Interest = $\frac{15000 \times 0.5 \times 5}{100}$

= $375

If P= $12000

Interest = $\frac{12000 \times 0.5 \times 5}{100}$

= $300

Difference between the interest = $75

c) Taking loan of the whole amount that is of $15,000 is more reasonable because though the interest is more but Troy will receive interest($300) from his savings account as well. But if he withdraws $3000 from savings and takes the loan for the rest of the amount, he would have no earnings.

Meryl needs to add enough water to 11 gallons of an 18% detergent solution to make a 12% detergent solution. Which equation can

notka56 [123]

We're measuring a quantity of pure detergent.

We start with 11 gallons of an 18% solution. 18% of that, or 1.98 gallons, is pure detergent, and the rest of these 11 gal. is water: 9.02 gal. We will add x gallons of water to this solution to obtain (11+x) gallons of a 12% solution.

We need to find x to satisfy this equation:

(11 gallons + x)(0.12) = (11 gallons)(0.18)

Div. both sides by 0.12, we get (11 gallons + x) = (11 gallons)(1.5)

Mult. both sides by 10, we get 110 gallons + 10x = (11 gallons)(15)

Then 10x = 165 gallons - 110 gallons, or 55 gallons.

Div. both sides by 10, we get x = 5.5 gallons (answer)
