A toy manufacturer uses 90 pints of plastic to make 600 action figures. If they use 810 pints of plastic in an 8 hour shift, how

lutik1710 [3]

Answer:

The number per hour = 5400 ÷ 8 = 675 action figures

Step-by-step explanation:

* Lets explain how to solve the problem

- A toy manufacturer uses 90 pints of plastic to make 600 action figures

- they use 810 pints of plastic in an 8 hour shift

- To find how many action figures are made per hour we must to find

how many action figures in an 8 hour shift and then find the number

of the action figures per hour

∵ The toy manufacture uses 90 pints of plastic to make 600 action

figures

∵ They use 810 pints

- Lets find how many action figures are made by this numbers of pints

∴ 90/600 = 810/x ⇒ x is the number of action figures

- Use the cross multiplication to find x

∴ 90 x = 810 × 600

∴ 90 x = 486000 ⇒ divide both sides by 90

∴ x = 5400

∴ They will use 810 pints to make 5400 action figures

∵ They use 810 pints in an 8 hour shift

∴ They make 5400 action figures in 8 hours

- To find the number of the action figures per hour divide the number

of them in 8 hours by 8

∴ The number per hour = 5400 ÷ 8 = 675 action figures

GuDViN [60]

Total number of puppies = 12
Where;
Poodles = 3
Terriers = 5
Retrievers = 4

After Rebecca selects a poodle, total number of puppies remaining = 12 -1 =11
Then,
Probability of Aaron selecting a retriever:

P(R) = Number of retrievers/New total = 4/11

Find the measure of the largest angle in the triangle

tester [92]

Answer:

72°

Step-by-step explanation:

Find the image of the question attached

The sum of angle in a triangle is 180°

Hence:

15x+24x+21x = 180°

60x =180

x =180/60

x= 3

Get the largest angle

The largest angle out of the angles is 24x

24x =24(3)

24(3) =72°

Hence the measure of the largest angle is 72°

The sides of an oblong are in the ratio of 4:3. The oblong has a length of 12 cm and is increased by a scale factor of 2.5. What

Aleksandr [31]

Answer:

If the scale factor is increased in 2.5, the increased width will be:

22.5 cm

Step-by-step explanation:

Remember that an oblong is longer than it is wide, by this reason, the ratio of 4:3 could mean, if we give a number, by each 4 cm in the length, there is 3 cm in the width, in this form, if the oblong has a length of 12 cm, the width is:

4 cm ⇒ 3 cm
12 cm ⇒ x

So:

$x=\frac{12 *3}{4}$
$x=\frac{36}{4}$
$x=9$

Then, the original width is 9 cm, as the scale factor must be increased 2.5, we can multiply the found width to obtain the increased width:

Increased width = 9 cm * 2.5
Increased width = 22.5 cm

As you can see, the increased widt will be 22.5 cm.
