Answer:

$12.25

Step-by-step explanation:

We can solve this by first finding 75% of $7. To do this, we can do $7.00 x 0.75. The product of those is 5.25. Knowing that $5.25 is 75% of $7, we are able to add up $7 and $5.25, which gives us $12.25.

Hope this helped!

Earl invested 6,000 in a money market account that pays 5% interest quarterly. How much money will he have in his account after

Sedbober [7]

Answer:

The amount becomes $6964.53 after 3 years .

Step-by-step explanation:

Formula

$Amount = P (1+\frac{r}{4})^{4t}$

Where P is the principle , r is the rate of interest in the decimal form and t is the time in the years .

As given

Earl invested 6,000 in a money market account that pays 5% interest quarterly for 3 years .

P = $6000

5% is written in the decimal form.

$= \frac{5}{100}$

= 0.05

r = 0.05

t = 3 years

Putting all the values in the formula

$Amount = 6000(1+\frac{0.05}{4})^{4\times 3}$

$Amount = 6000(1+0.0125)^{12}$

$Amount = 6000\times 1.16075452$

$Amount =\$ 6964.53\ (Approx)$

Therefore the amount becomes $6964.53 after 3 years .

The minute hand of a clock is 9 inches long. how far does the tip of the minute hand move in 40 minutes

GarryVolchara [31]

$\text{The minute hand of a clock is 9 inches long.}\\
\text{we need to find the distance traveled by the tip of the minute }\\
\text{hand moved in 40 minutes.}$

$\text{That is we need to find the length of the arc formed by the minute}\\
\text{hand in 40 minutes. We know that in one complete revolution of the}\\
\text{minute hand there are 60 minutes. so the central angle formed by the }\\
\text{minute hand in 40 minutes is}=\frac{40}{60}*2\pi =\frac{4\pi}{3} \text{ radians}\\
\\
\text{hence using the arc length formula, }s=r\theta, \text{ we get}\\
\\
\text{distance traveled by the tip}=9\times \frac{4\pi}{3}=12\pi\approx 37.7 \text{ inches}$

Hence the tip of the minute hand moved approximately 37.7 inches in 40 minutes.

Calculate the distance between (4,9) and (-2,6) using the distance formula.

MAVERICK [17]

Answer:

$\large\boxed{d=3\sqrt5}$

Step-by-step explanation:

$\text{the formula of a distance between two points}\ A(x_1,\ y_1)\ \text{and}\ B(x_2,\ y_2):\\\\|AB|=\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}\\=========================\\\\\text{We have}\ (4,\ 9)\ \text{and}\ (-2,\ 6).\ \text{Substitute:}\\\\d=\sqrt{(-2-4)^2+(6-9)^2}=\sqrt{(-6)^2+(-3)^2}=\sqrt{36+9}=\sqrt{45}\\\\\sqrt{45}=\sqrt{9\cdot5}=\sqrt9\cdot\sqrt5=3\sqrt5$
