Answer:

28.56

Step-by-step explanation:

First we need to calculate the mean average of the numbers

Average = 112+89+95+77+103/5

Average = 476/5

Average = 95.2

If Sam made 30% of goals in his last 6 games, then on average, amount made is expressed as;

Average of the last six games = 30% of 95.3

Average of the last six games  = 0.3 * 95.2

Average of the last six games = 28.56

Hence the required point average is 28.56

A car advertisement states that a certain car can accelerate from rest to 70 km/h in 7 seconds. Find the cars average accelerati
Ray Of Light [21]

Answer:

v_0(initial velocity)           v_f(final velocity)     a(acceleration)

v_0=70 km/h    v_f= 0 km/h( rest)

Kinematics equation is a=(v_f-v-0)/time

a=(0-70)/(7/3600)  which means it decelerates at -36000 km/h

This number is humongous; I would advise you to re-check the problem and see if the the time it takes is 7 hours rather than 7 seconds. Notice that I put the time as 7/3600 because it is 7 seconds which should be converted to hours.

Marina had 24,500 to invest. She divided the money into three different accounts. At the end of the year, she had made RM1,300 i
galben [10]

Answer:

See below

Bold parts are important parts. They are the equations.

Marina had RM24,500 to invest.

If the amount of money in the 4% account was four times the amount of money in the 5.5% account.

" At the end of the year, she had made RM1,300 in interest. The annual yield on each of the three accounts was 4%, 5.5%, and 6%."

"If the amount of money in the 4% account was four times the amount of money in the 5.5% account,"

a = 4b

Down is the equations.

let a = amt in the 4% acct

let b = amt in the 5.5% acct

let c = amt in the 6%

"Marina had RM 24,500 to invest."

a + b + c = 24500

Replace a with 4b in both equations, simplify

b = $2000 in the 5.5% investment

a = $8000 in the 4% acct

Ok, so
Length = L
Width = L + 7

Since area = length x width, then

30 = L × (L + 7)

Remember that L + 7 Is width so...

L + 7 = 30/L

So the expression for the width in terms of length would be...
w = 30/L - 7

Hello! Please help thanks
kogti [31]

Answer:

A. \frac{5}{13}

Step-by-step explanation:

Hi there!

We are given right triangle PQR, with PR=5, RQ=12, and PQ=13

We want to find the value of sin(Q)

Let's first recall that sine is \frac{opposite}{hypotenuse}

In reference to angle Q, PR is the opposite side, RQ is the adjacent side, and PQ is the hypotenuse

So that means that sin(Q) would be \frac{PR}{PQ}

Substituting the values of PR and PQ gives sin(Q) as \frac{5}{13}, which is A

Hope this helps!

Two friends board an airliner just before departure time. There are only 11 seats left, 4 of which are aisle seats. How many way
Vadim26 [7]

Using the Fundamental Counting Theorem, it is found that:

The 2 people can arrange themselves in 40 ways.

<h3>What is the Fundamental Counting Theorem?</h3>

It is a theorem that states that if there are n things, each with n_1, n_2, \cdots, n_n ways to be done, each thing independent of the other, the number of ways they can be done is:

N = n_1 \times n_2 \times \cdots \times n_n

With one people in the aisle and one in the normal seats, the parameters are:

n1 = 4, n2 = 7

With both in the aisle, the parameters is:

n1 = 4, n2 = 3

Hence the number of ways is:

N = 4 x 7 + 4 x 3 = 28 + 12 = 40.
