The radius of a basketball is about 13 centimeters.<br> What is the volume of the basketball?

Yesterday, teddy played a game repeatedly on his computer and won exactly 85% of the games he played. today, teddy played the sa

The equation we use here is:
$(0.85)x +(1.00)y = (0.94)(x + y)$
x is for the number of games he played on first day, y is the games on second day. The coefficients are the decimal form of percentages.

Simplify:
$0.85x + y = 0.94x + 0.94y \\ \\ 0.06y = 0.09x \\ \\ \frac{6y}{100} = \frac{9x}{100} \\ \\ 6y = 9x \\ \\ 2y = 3x$

To find x we need to use the ratio. We have 85/100 as the first day's ratio and because the games needs to be whole, we can simplify this as 17/20. So in first day, he played at least 20 games and won 17 of them.

When we plug the 20 into the equation as x:
$2y = 3 \times 20 \\ \\ 2y = 60 \\ \\ y = 30$
So he needs to play at least 30 games in order to get his score to 94%.

vivado [14]

Answer:

The value of Nick's consumer surplus for the milkshakes he buys is $3.

Step-by-step explanation:

Given : Nick can purchase each milkshake for $2. For the first milkshake purchased Nick is willing to pay $4, for the second milkshake $3, for the third milkshake $2 and for the fourth milkshake $1.

To find : What is the value of Nick's consumer surplus for the milkshakes he buys?

Solution :

Nick can purchase each milkshake for $2.

For 1st milkshake purchased Nick is willing to pay $4

Consume surplus $4-$2=$2

For 2nd milkshake purchased Nick is willing to pay $3

Consume surplus $3-$2=$1

For 3rd milkshake purchased Nick is willing to pay $2

Consume surplus $2-$2=$0

For 4th milkshake purchased Nick is willing to pay $1

Consume surplus $1-$2=$-1 cannot be consider.

We add together the surplus from the 1st, 2nd, 3rd, and 4th milkshake

i.e. $2+$1+$0=$3

Therefore, the value of Nick's consumer surplus for the milkshakes he buys is $3.

A businessman bought a fairly used radio set for 950 dollars and spent 250 dollars for repairing it before selling it for 1500 d

horrorfan [7]

I believe it's a 25% profit.

950+250= 1200

1500-1200= 300

300/1200= 0.25

0.25 x 100= 25%

Bianca reads 3/4 of a page of a book each minute. She has 25 pages left to read. How many pages will she read in 5 1/2 minutes?

Viktor [21]

Answer:

Bianca reads a page of a book in 1 ÷ (3/4) = 1 x (3/4) = 4/3 minutes;

We have 5 1/2 = 11/2 minutes;

She reads (11/2) ÷ (4/3) = (11/2) x (3/4) = 33 /8 = 4 1/8 pages;
