Use the right triangular prism to find the total surface area of the prism. Leave label off answer.

9966 [12]

Step-by-step explanation:

the total surface area is the sum of the 5 individual areas in the surface :

2 triangle sides (left and right).

1 back rectangle side

1 rectangle floor

1 inclined rectangle front side

to get the length of the baseline (Hypotenuse) of the right-angled triangles on the side. we use Pythagoras

c² = a² + b²

where c is the Hypotenuse (the side opposite of the 90° angle).

c² = 3² + 4² = 9 + 16 = 25

c = 5

so, now, we have everything we need.

the area of a triangle side (since it is right-angled) :

4×3/2 = 6

2 sides, that makes 12

the area of the back side

6×3 = 18

the area of the floor

6×4 = 24

the area of the inclined front side

6×5 = 30

so, the total surface area is

12+18+24+30 = 84

jenny charges $9.15 an hour to babysit toddlers and $7.45 an hour to babysit school-aged children, if jenny babysat toddlers for

choli [55]

The total money earned by Jenny is $\boxed{\bf \$\ 127.05}$ .

Further explanation

Multiplication is a arithmetic operation such that two real numbers are performed in such a way that they derive a third number called product.

Procedure used:

The following steps are involved to find the value of $y\text{ unit}$ where $y$ is any real number.

1) If one unit is equal to $x$ then multiply $y$ with $x$ .

2) The resultant number would be $xy$ is the value of $y\text{ unit}$ .

Given:

Jenny charges $\$\ 9.15$ an hour to babysit toddlers and $\$\ 7.45$ an hour to babysit school-aged children. She babysat toddlers for $9\text{ hours}$ and school aged children for $6\text{ hours}$ .

Calculation:

Step 1: Jenny earns through babysit toddlers.

If jenny charges $\$\ 9.15$ an hour to babysit toddlers and she does this job for $9\text{ hours}$ .

The earning money from babysit toddlers using above procedure can be calculated as follows:

$\begin{aligned}a&=9.15\cdot 9\\&=82.35\end{aligned}$

Therefore, jenny earns $\$\ 82.35$ by babysit toddlers.

Step 2: Jenny earns through school aged children.

If jenny charges $\$\ 7.45$ an hour to babysit school aged children and she does this job for $6\text{ hours}$ .

The earning money from babysit school aged children using above procedure can be calculated as follows:

$\begin{aligned}b&=7.45\cdot 6\\&=44.7\end{aligned}$

Therefore, Jenny earns $\$\ 44.7$ by babysit school aged children.

Step 3: Total amount earn by Jenny.

The total earning is the sum of earning through babysit toddlers and babysit school aged children.

The total earning is calculated as follows:

$\begin{aligned}\text{Total money}&=82.35+44.7\\&=127.05\end{aligned}$

Thus, total money earned by jenny is $\boxed{\bf \$\ 127.05}$ .
