dezoksy [38]

Answer:

The age of Mr. Collins is 30 years and

The model which represent the problem is, The age of Mr. Collins is 3 × 10

Step-by-step explanation:

Given as :

The age of Adam = 10 years

The age of Mr. Collins = x years

The age of Mr. Collins = 3 times the age of Adam

Or, x = 3 × The age of Adam

Or, x = 3 × 10

∴ x = 30

So, The age of Mr. Collins = x years = 30 years

The model which represent the problem is, The age of Mr. Collins = 3 × 10

Hence The age of Mr. Collins is 30 years and

The model which represent the problem is, The age of Mr. Collins = 3 × 10

Joe's Ice Cream Shop has 7/8 of a gallon of vanilla ice cream left. They use 1/12 of a gallon of ice cream to make one milkshake

Vadim26 [7]

Answer:

Ten and a Half milkshakes can be prepared from the available amount of ice cream.

Step-by-step explanation:

The total vanilla ice cream = 7/8 gallons

Ice cream used for 1 milkshake = 1/12 gallon

Now, total number of milkshakes possible = $\frac{\textrm{Total availibility of ice cream}}{\textrm{Ice cream used for each milkshake}}$

= $\frac{\frac{7}{8} }{\frac{1}{12} } = \frac{7}{8} \times \frac{12}{1} = 10.5$

Hence ten and a half milkshakes can be prepared from the available amount of ice cream.

Julie has 5 cherry lollipops,1 lime lollipops, and 2 grape lollipops in a bag. She is going to select one lollipop, replace the

Georgia [21]

Answer: $\dfrac{15}{32}$

Step-by-step explanation:

Given : The number of cherry lollipop = 5

The total number of lollipop = 8

the number of lollipops other than grape =6

The probability of selecting a cherry lollipop is given by :_

$\text{P(Cherry)}=\dfrac{5}{8}$

The probability of selecting a lollipop other than grape is given by :_

$\text{P(Other than grape)}=\dfrac{6}{8}$

Since, there is replacement , then the events are independent of each other.

Now, the probability that Julie will select a cherry lollipop and then a lollipop other than grape is given by :-

$\text{P(Cherry and other than grape)}=\dfrac{5}{8}\times\dfrac{6}{8}=\dfrac{15}{32}$

Hence, the required probability = $\dfrac{15}{32}$
