Answer:

hj = 11

Step-by-step explanation:

  • (h+j)^2=73,\:\: and\:\: h^2+j^2 =51 (Given)

  • (h+j)^2 = h^2+j^2 +2hj

  • \implies 73= 51 +2hj

  • \implies 73- 51 =2hj

  • \implies 22 =2hj

  • \implies hj = \frac{22}{2}

  • \implies hj = 11

Choose all that state the correct unit rate for each situation. 100 POINTS ASAP K12
Lorico [155]

Answer:

Please see the answers below:

Step-by-step explanation:

The wrong answers are deleted only the correct answers are listed below:

  • Ryan earns $45 for 5 hours of work. The unit rate is $9 for 1 hour.
  • Jenna can drive her car 110 miles on 5 gallons of gasoline. The unit rate is 22 miles per gallon.
  • Claire saves $320 in 16 weeks. The unit rate is $20 per week.

  • % increase in price of gas = [(New Price - Original Price) / Original Price] x 100

% increase in price of gas = [($2.48 - $2.18) / $2.18] x 100

% increase in price of gas = [$0.3 / $2.18] x 100

% increase in price of gas = 13.76%

Aysha has 40 cubes in a bag.
marissa [1.9K]

Given:

Total number of cubes = 40

Red cubes = 18

Blue cubes = 13

Yellow cubes = 9

Aysha adds some more red cubes into the bag.

The probability now that she will take a red cube is 0.5.

To find:

The probability that she will take a yellow cube.

Solution:

Let Aysha adds x red cubes into the bag. Then,

Number of total cubes = 40+x

Number of red cubes = 18+x

Probability of getting a red cube is:

P(Red)=\dfrac{18+x}{40+x}

The probability now that she will take a red cube is 0.5. So,

\dfrac{18+x}{40+x}=0.5

18+x=0.5(40+x)

18+x=20+0.5x

x-0.5x=20-18

0.5x=2

Divide both sides by 0.5.

x=\dfrac{2}{0.5}

x=4

It means Aysha adds 4 more red cubes into the bag.

Now, the total number of cubes int he bag is:

40+4=44

Probability of getting a yellow cube is:

P(Yellow)=\dfrac{\text{Number of yellow cubes}}{\text{Total number of cubes}}

P(Yellow)=\dfrac{9}{44}

Therefore, the required probability is P(Yellow)=\dfrac{9}{44}.
