Dahasolnce [82]

Answer:

The total number of students in the gymnastics are <u>70</u>.

Step-by-step explanation:

Given:

Fifty-six students in a gymnastics club participated in the last fundraiser.

In the gymnastics club 80% of the students in the club participated in the fundraiser.

Now, to find the total number of students in the gymnastics.

Let the total number of students be $x.$

Number of students participated in the club = 56.

Percent of students participated in the club = 80%.

According to question:

$80\%\ of\ x=56$

$\frac{80}{100} \times x=56$

$0.8\times x=56$

<em>Dividing both sides by 0.8 we get:</em>

$x=70.$

Therefore, the total number of students in the gymnastics are 70.

Kendra invested twice as much money at an annual rate of 7% as she did at an annual rate of 5.5%. How much did she invest at the

Lady bird [3.3K]

Answer:

$1,679.42

Step-by-step explanation:

Let $x$ be the amount Kendra invested at 5.5%. Since the amount invested at 7% is twice the amount she invested at 5.5%, she invested $2x$ at 7%.

Remember that $I=Prt$ , where:

$I$ is the interest earned

$P$ is the principal or initial investment

$r$ is the interest rate in decimal form

$t$ is the time in years

- For the 5.5% investment:

$P=x$

$r=\frac{5.5}{100} =0.055$

$t=1$

Let's replace the values in our formula, $I=x(0.055)(1)$ , which simplified is $I=0.055x$

- For the 7% investment:

$P=2x$

$r=\frac{7.7}{100} =0.077$

$t=1$

$I=2x(0.077)(1)$

$I=0.154x$

Now, we that the the amount of interest earned combining the two investment is $175.50, so:

$0.055x+0.154x=175.50$

$0.209x=175.50$

$x=\frac{175.50}{0.209}$

$x=839.71$

She invested $839.71 at 5.5%, and since she invested twice that amount at 7%, she invested 2*($839.71 ) = $1,679.42 at 7% (the higher rate).

Hayley and Tyler are on the cross-country team. Tyler can run 1 mile (at a

ANTONII [103]

The person who ran farther is Hayley.

<h3>Who ran farther?</h3>

Average speed is the total distance travelled per time.

Average speed = total distance / total time

Tyler's average speed = 1 / 8.30 seconds = 0.12 miles per minute

The distance covered by Tyler in 10 minutes = 0.12 x 10 = 1.2 miles

Distance covered by Hayley in 10 minutes : 10 = 8x

x = 10 / 8 = 1.25 miles
