\boxed{h=7cm}

<h2>Explanation:</h2>

The formula for finding the area of any triangle is given by:

A=\frac{bh}{2} \\ \\ \\ Where: \\ \\ b:base \\ \\ h:height

Let's assume a value for the area, we know that:

b=5\frac{1}{4}cm=(5+\frac{1}{4})cm=\frac{21}{4}cm=5.25cm \\ \\ A=\frac{147}{8}cm^2=18.375cm^2 \\ \\ h=?

Finding h:

A=\frac{bh}{2}  \\ \\ \\ Isolating \ h: \\ \\ h=\frac{2A}{b} \\ \\ h=\frac{2(18.375)}{5,25} \\ \\ h=7cm

24 is 31.25% of what number? Prove your answer in the show your workbox.
FinnZ [79.3K]

Answer:

76.8

Step-by-step explanation:

1. We assume, that the number 31.25 is 100% - because it's the output value of the task.

2. We assume, that x is the value we are looking for.

3. If 100% equals 31.25, so we can write it down as 100%=31.25.

4. We know, that x% equals 24 of the output value, so we can write it down as x%=24.

5. Now we have two simple equations:

1) 100%=31.25

2) x%=24

where left sides of both of them have the same units, and both right sides have the same units, so we can do something like that:

100%/x%=31.25/24

6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 24 is what percent of 31.25

100%/x%=31.25/24

(100/x)*x=(31.25/24)*x       - we multiply both sides of the equation by x

100=1.3020833333333*x       - we divide both sides of the equation by (1.3020833333333) to get x

100/1.3020833333333=x

76.8=x

x=76.8

now we have:

24 is 76.8% of 31.25

A store is holding a grand opening promotion. Every 3rd customer receives a free key chain and every 4th customer receives a fre
Archy [21]

Answer:

12th Customer

Step-by-step explanation:

We have to find the lcm (lowest common multiple) of the number.

We do that by taking their multiples. Watch down below

3 x 1 = 3                4 x 1 = 4

3 x 2 = 6               4 x 2 = 8

3 x 3 = 9               4 x 3 = 12

3 x 4 = 12

See how they both have a 12 as their first lcm.

So the 12th customer gets both items.

Glad to help!

An old movie theater charges $4 for an adult and $2 for a child's ticket. One night, 380 tickets were sold for a total of $1320.
insens350 [35]

Answer: 0

Step-by-step explanation:

Let statements :

Let x be the number of tickets sold for an adult

Let y be the number of tickets sold for a child

Equations :

x + y = 280  OR  y = 280 - x

4x + 2y = 1320

Substitution (sub the 2 equations in together) :

4x + 2(280 - x) = 1320

4x + 560 - 2x = 1320

2x = 1320 - 560

x = 760/2

x = 380

x is the number of tickets sold for the adults. meaning that 380 adults went.

Find the # of children :

x + y = 380

we know that x = 380

380 + y = 380

y = 380 - 380

y = 0

Conclusion :

No children went because the movie was rated R. Only adults attended.
