worty [1.4K]

Answer:

For 4 years the money was in the account .

Step-by-step explanation:

Formula

$Simple\ interest = \frac{Principle\times Rate\times Time}{100}$

As given

Bonita deposited 1300 into a bank account that earned 5.75% simple interest each year.

She earned $299 in interest before closing the account.

Principle = $1300

Rate = 5.75%

Simple interest = $299

Putting all the values in the formula

$299 = \frac{1300\times 5.75\times Time}{100}$

$Time= \frac{299\times 100}{1300\times 5.75}$

$Time= \frac{29900\times 100}{1300\times 575}$

$Time= \frac{2990000}{747500}$

Time = 4 years

Therefore for 4 years the money was in the account .

Alejandro has gone to school StartFraction 5 Over 7 EndFraction of the last 35 days. Which expression can be used to determine t

Arte-miy333 [17]

Answer:

Expression B

Step-by-step explanation:

Let us find the information in the question

Alejandro has gon to school $\frac{5}{7}$ of the last 35 days
We need to find the expression that represents the number of days Alejandro has gone to school.

We must write the given information in an expression then look for it in the choices.

∵ He has gone $\frac{5}{7}$ of 35 days

→ "of" means times (×)

∴ The days that he has gon = 35 × $\frac{5}{7}$

The expression that can be used to determine the number of days he has gone to school is 35 × $\frac{5}{7}$

The choices are:

A) $\frac{35}{7}=\frac{5}{7}$

B) 35 × $\frac{5}{7}$

C) $\frac{5}{7}$ ÷ 35

D) $\frac{7}{5}$ ÷ 35

The answer is B

The weight of a rock sample is measured to be 2.5 pounds. What is the percent of error in the measurement? 2% 5% 10%

elixir [45]

Answer:

The percent of error in the measurement is 2%

Step-by-step explanation:

The percent of error associated with a reported measurement is calculate using the formula;

$percenterror=\frac{error}{measurement}*100$

The error associated with a measurement is defined as half of the smallest unit of measurement used. The measurement reported was 2.5. The smallest unit of measurement for this reading is 0.1. The error is thus;

error = 0.1/2 = 0.05

The percent of error is thus;

$\frac{0.05}{2.5}*100=2$
