For each problem, identify any important quantities. If it's a known quantity, write the
Tema [17]

Answer:

We have the problem:

"Clare is in charge of getting snacks for a road trip with her friends and her dog. She has

$35 to go to the store to get some supplies. The snacks for herself and her friends cost

$3.25 each, and her dog's snacks costs $9 each."

In this situation we have two variables:

X =  number of snacks for herself and her friends that she buys. Each one of these costs $3.50

Y = number of snacks for her dog that she buys. Each one of these costs $9.

The total cost, in this case, can be written as:

X*$3.50 + Y*$9

And we know that she has $35 to spend, so she can spend $35 or less in the store, then we have the inequality:

X*$3.50 + Y*$9  ≤ $35

Where we defined all the quantities in the inequality.

6x+7y=4x+4y<br> (where y is -4 and the value of x is unknown)<br> find the value of x
faltersainse [42]

Answer:

x = 6

Step-by-step explanation:

Substitute y = - 4 into the equation and solve for x

6x + 7(- 4) = 4x + 4(- 4) ← evaluate

6x - 28 = 4x - 16 ( subtract 4x from both sides )

2x - 28 = - 16 ( add 28 to both sides )

2x = 12 ( divide both sides by 2 )

x = 6

If a large cylinder has a volume of 28260 cubic cm, how many cylinders can be filled out of the large cylinder if the small cyli
inysia [295]
Hi,

To find the number of small cylinders that fit inside the big cylinder. You need to divide volume of small cylinder with the volume of big cylinder. We do this by using formula to calculate volume of cylinder:


v = \pi \times  {r}^{2}  \times h


To find radius just divide diameter with 2.

v = \pi \times   {2}^{2}  \times 6 \\ v = \pi \times 4 \times 6 \\ v = \pi \times 24 \\ v = 3.14 \times 24 \\ v = 75.4 {cm}^{3}


Now just division:

28260 \div 75.4 = 374.8

Answer: You could fit 374.8 smaller cylinders inside a big cylinder.

Hope this helps.

ch4aika [34]

Answer: $205.33

Step-by-step explanation:

We know the original price was $234, during the sale there was a 35% discount, let's found out what that is...

234 * (100% - 35%)

234 * (65%)

234 * (0.65)

= 152.1

After the sale, the price was increased by 35%, remember percentages are out of 100...

100% + 35% = 135%

135% = 1.35

152.1 * 1.35

= $205.33

The price of the camera after the increase is $205.33, I hope this helps!
