Answer:

She spends $\frac{4}{5}$ hours total.

Step-by-step explanation:

Janice spends $\frac{1}{10}$ hour making the bed , $\frac{1}{5}$ hour getting dressed and and half hour eating breakfast.

We have to find the total time she spends for all these activities and that too in simplest form. The main concept here is that when we are adding fractions, the denominators should be common for all the fractions.For that we make 10 as the common denominator here .

Then the fractions are $\frac{1}{10} ,\frac{2}{10} ,\frac{5}{10}$ .

Now we can simply add these fractions.

Sum = $\frac{1}{10} +\frac{2}{10} +\frac{5}{10}$

sum = $\frac{8}{10}$

Sum = $\frac{4}{5}$

Yakvenalex [24]

Answer:

Each of them spent $9.35 on meal.

Step-by-step explanation:

Jacob and his three friends ordered an individual pizza and a drink for $6.19.

Total cost of pizza and drink = 6.19 × 4

= $24.76

They also ordered bread sticks for $4.25

Tax on the bill was = $2.39

Tip amount was = $1.50×4 = $6.0

So the total billed amount will be = 24.76 + 4.25 + 2.39 + 6

= $37.4

Since there were four persons including Jacob.

Therefore, each person spend on meal = $\frac{37.40}{4}$

= $9.35

A zookeeper weighed an African elephant to be 9x10^3 pounds and an African lion to be 4x10^2 pounds. How many times greater is t

maria [59]

Answer: 22.5 . The weight of the elephant is "22.5 times greater" than the weight of the lion.
_________________________________________________________
Explanation:
_________________________________________________________

(weight of lion) * (x) = (eight of the elephant) ; Solve for "x" .
_____________________________________________________
→ Divide each side of the equation by "(weight of lion)" ;
to isolate "x" on one side of the equation ; and to solve for "x" ;
_________________________________________________________

→ (weight of lion)*(x) / (weight of lion) = (weight of the elephant) /
(weight of lion) ;
________________________________________________________
→ x = (weight of the elephant) / (weight of lion) ;
__________________________________________________________
→ Plug in our "given values" ; and solve for "x" ;
__________________________________________________________
→ x = (<span>9*10</span>³) / (4*10²) = (9*10⁽³⁻²⁾) / 4 = (9*10¹) / 4 ;
__________________________________________________________
→ x = 90 /4 = 25/2 = 22.5 ; which is our answer.

Moby sold half his toy car collection, and then bought 12 more cars the next day. He now has 48 toy cars. How many cars did he h

castortr0y [4]

Answer: 72 cars.

Step-by-step explanation:

Let be "x" the number of toys that Moby had to start with.

According to the information given in the exercise, Moby sold half his toy car collection. This can be represented with the following expression:

$\frac{1}{2}x$

Then he bought 12 more cars, giving a total amount of 48 toy cars.

Therefore, the equation that represents this situation is the equation shown below:

$x-\frac{1}{2}x+12=48$

Now you must solve for "x" in order to find its value.

You get that this is:

$\frac{1}{2}x+12=48\\\\\frac{1}{2}x=48-12\\\\\frac{1}{2}x=36\\\\x=(36)(2)\\\\x=72$
