Answer:

2 Teaspoons

___________________________________________

So, we know that the original amount for salt is 1/2.

So, we do 1/2 x 4

1/2 x 4 = 2

So, the answer is 2

Bernie played 3 rounds of golf, and the mean of his score was 78. If his lowest score was 74, what is the greatest possible valu

zmey [24]

Answer:

85.

Step-by-step explanation:

Let x represent Bernie's highest score.

We have been given that Bernie played 3 rounds of golf, and the mean of his score was 78. His lowest score was 74.

Since Bernie's lowest score is 74, so we can assume that his score on 2nd round would be 75.

Now, we will use mean or average formula to solve our given problem.

$\text{Mean}=\frac{\text{Sum of all data points}}{\text{Number of data points}}$

$78=\frac{74+75+x}{3}$

Let us solve for x.

$78\cdot 3=\frac{74+75+x}{3}\cdot 3$

$234=74+75+x$

$234=149+x$

$x=234-149$

$x=85$

Therefore, the greatest possible value of his highest score would be 85.

The number is 3947

It should be noted that 36 hundreds will be equal to:

= 36 × 100

= 3600

It should be noted that 34 tens will be:

= 34 × 10

= 340

7 ones will be:

= 7 × 1

= 7.

Therefore, the sum will be:

= 3600 + 340 + 7 = 3947

Can someone help me out? This is really hard! (brainliest if it's correct!)

Andrews [41]

Step-by-step explanation:

Lets convert the time she spend working into a improper fraction.

$4 \frac{1}{2} = \frac{4 \times 2 + 1}{2} \\ = \frac{9}{2} hours$

Since she spend 2/5 of the above time mowing lawns,

Time Spend mowing lawns =

$\frac{2}{5} \times \frac{9}{2} \\ = \frac{2 \times 9}{5 \times 2} \\ = \frac{18}{10} hours \\ = \frac{18 \div 2}{10 \div 2} \\ = \frac{9}{5} hours \\ = 1 \frac{4}{5} hours \: or \: 1.8 \: hours$
