Answer:

2.5, 5/2, 25/10

Step-by-step explanation:

it is in the the middle of both 2 and 3, which 2.5, 5/2, and 25/10 all equals to 2.5.

5/2 = 2.5

25/10 = 2.5

How to do the problem

Veronika [31]

Ill work it out w/ the steps so you can do it later on. STEP 1) multiply 95 by .10 to get 9.5 STEP 2) subtract 9.5 from 95 to get 85.5, your new price STEP 3) multiply 85.5 by 1.045 *mini step to get 1.045: add 4.5 to 100, get 104.5, divide by 100, get 1.045* then you get $89.35

What is the volume of the oblique cylinder rounded to the nearest cm^3?

SVETLANKA909090 [29]

Answer: $32009355.90cm^3$

Step-by-step explanation:

Formula: $V=Bh\\$

Since the base is a circumference, we can replace B for the area of a circumference formula.

$V=\pi r^2h$

What we have here is 12 ft as the diameter of the circumference. A diameter is twice the radius, therefore we can conclude that if we take the diameter and divide it by 2, it will give us the radius.

$12/2=6ft$ this is the radius.

Now plug all this information into your formula.

$V=(3.14)(6ft)^2(10ft)\\V=(3.14)(36ft^2)(10ft)\\V=1130.40ft^3$

Our values are in feet but the question requires cm. Let's convert from $ft^3$ to $cm^3$ .

Normally, our conversion factors are raised to the power of 1, but in this case it's raised to the power of 3. So, first let's see how many cm are 1 ft.

$1ft=30.48cm$

Here is where magic comes. We can raise both to the power of 3, in order to find the cubic ft and cm that we need as our conversion factors.

$(1ft)^3=(30.48cm)^3\\1ft^3=28316.8cm^3$

Now we have our conversion factors.

$1130.40ft^3(\frac{28316.84cm^3}{1ft^3})=32009355.90cm^3$

Find all the natural numbers, which when divided by 7, leave the same number for the quotient and the remainder.

Anna11 [10]

Answer:

8,16,24,32,48

Step-by-step explanation:

When dividing a number by 7, only 7 different remainders are possible.

The remainders when dividing by 7 can not exceed 6, so the numbers in which we are interested can be represented as 7k+k or just 8k, where k=1, 2, ... , 6.
