Answer:

The mean will reduce

Step-by-step explanation:

The total amount of money for the ten days divided by number of days will give mean 1, M₁

Removing the value for day seven will reduce the sum of money as it will be for 9 days only.In finding the mean, you will divide by 9 days to get mean M₂

Mean M₂ < M₁

Express 30p as a fraction of £3.00
neonofarm [45]

Answer:

\frac{1}{10} \£

Step-by-step explanation:

We know that £1 equals 100p.

Knowing this relation, we can use the rule of three

30p \times \frac{ \£1}{100p} =0.3 \£

Then, we form the fraction

\frac{0.3 \£}{\£ 3.00} =\frac{3}{30} =\frac{1}{10} \£

Therefore, the fraction of of £3.00 is

\frac{1}{10} \£

Nakita rode her skateboard at an average speed of 8.8 feet per second for 0.2 miles. She wants to calculate how long it took her
timama [110]

Answer: 2\ minutes

Step-by-step explanation:

We know that:

d=rt

Where "d" is distance, "r" is rate and "t" is time.

Solved for the time "t":

t=\frac{d}{r}

The first step is to convert the distance from miles to feet.

Since 1\ mile=5,280\ feet, we get:

d=(0.2\ mi)(\frac{5,280\ ft}{1\ mi})\\\\d=1,056\ ft

Knowing that:

r=8.8\ \frac{ft}{s}

We can substitute values into t=\frac{d}{r} in order to find the time in seconds:

t=\frac{1,056\ ft}{8.8\ \frac{ft}{s}}\\\\t=120\ s

Since:

1\ minute = 60\ seconds

The time in minutes is:

t=(120\ s)(\frac{1\ min}{60\ s})\\\\t=2\ min

brilliants [131]

Question:

After a storm damages the community center, Shanika and her friends hold fundraising events to help pay for repairs. After the first event, they raise $240, which is 10% of the total amount that they want to raise. What is the total amount of money that Shanika and her friends want to raise?

Answer:

The total amount of money that Shanika and her friends want to raise is $2400

Step-by-step explanation:

Here we have the amount raised = $240

Also we are told that the amount raised is only 10% of the amount they want to raise

Therefore if we put the amount they want to raise as D we have

10% of D = $240

That is;

\frac{10}{100} \times D = \$240

That means

D = \$240 \times  \frac{100}{10}  = 10 \times  \$240 = \$2400

Therefore, the total amount of money that Shanika and her friends want to raise = $2400.
