Question

The stack on the left is made up of 15 pennies, and the stack on the right is also made up of 15 pennies. If the volume of the stack of pennies on the left is 390 mm3, what is the volume of the stack of pennies on the right in cubic millimeters?

Solution 1

**Answer:**

390 would be the answer

**Step-by-step explanation:**

they are literally the same thing.

Solution 2

I was told the answer was 375mm3

Question

The stack on the left is made up of 15 pennies, and the stack on the right is also made up of 15 pennies. If the volume of the stack of pennies on the left is 390 mm3, what is the volume of the stack of pennies on the right in cubic millimeters?

Solution 1

**Answer: The required volume is 390 mm³.**

**Step-by-step explanation: ** Given that the stack on the left is made up of 15 pennies, and the stack on the right is also made up of 15 pennies. The volume of the stack of pennies on the left is 390 mm³.

we are to **find the volume of the stack of pennies on the right in cubic millimeters.**

The number of pennies on the left and right are same, **equal to 15.**

Also, the **volume of the stack of pennies on the left is 390 mm³.**

Since the **number of pennies on the right and left are equal**, so the** volume of the stack on the right and left are also equal.**

**Therefore, the volume of the stack of pennies on the right is 390 mm³.**

**Thus, the required volume is 390 mm³.**

Solution 2

**Answer:**

The answer is 390 mm³

Question

Use Cavalieri’s Principle to calculate the exact volume of an oblique cylinder with a radius of 5 inches and a height of 16 inches.

Solution 1

**Answer:**

**Step-by-step explanation:**

**Cavalieri’s Principle:** If in two solids of equal altitude, the sections made by planes parallel to and at the same distance from their respective bases are always equal, then the volumes of the two solids are equal.

Thus, we are given that the radius of the cylinder is 5 inches and height is 16 inches, therefore volume of oblique cylinder is given as:

Substituting the given values,, we have

**Thus, the volume of the oblique cylinder is 400π cubic inches.**

Solution 2

V= (pi)r^29(h)

V= (pi) 25(16)

V= 400(pi) in^3

V= (pi) 25(16)

V= 400(pi) in^3

Question

Question

Alan is giving a basic math test in his class. One of the questions in the test is about finding two factors of the number 221. Which are the two factors of the given number? The two factors of the number 221 are ___ and ____.

Solution 1

The two factors of the number 221 are 13 and 17.

A factor refers to a whole number, which fits evenly into another whole number. Thus, factors are the numbers, which we multiply together to get another number. The two numbers that can be multiply together to get 221 are 13 and 17.

A factor refers to a whole number, which fits evenly into another whole number. Thus, factors are the numbers, which we multiply together to get another number. The two numbers that can be multiply together to get 221 are 13 and 17.

Solution 2

1,13,17 are three of them

Question

What is 4.6 repeating as a fraction???
please help!! :'(

Solution 1

Your answer would be 4 2/3.

Let

Let

x=4.66¯6

Then 10x=46.66¯6

So 10x−x=46.66¯6

4.66¯6.−−−−−−−− subtract

9x=42

Divide both sides by 9

x=429=423

Question

What is the approximate volume of a cylinder with a radius of 8 cm and height of 5 cm? A. 62.8
B. 251.2
C. 25.1
D. 502.4
E. 1004.8

Solution 1

V(cylinder)=πr² *h

r=8 cm

h=5 cm

V(cylinder)=πr² *h =3.14*8²*5= 1004.8 cm³

Answer : E.

r=8 cm

h=5 cm

V(cylinder)=πr² *h =3.14*8²*5= 1004.8 cm³

Answer : E.

Question

What is the y-intercept of x^2+2x+6

Solution 1

The y-intercept occurs when x = 0.

y = x^2 + 2x + 6

Let x = 0

y = 0^2 + 2 * 0 + 6

y = 6

Answer: 6

y = x^2 + 2x + 6

Let x = 0

y = 0^2 + 2 * 0 + 6

y = 6

Answer: 6

Solution 2

Y-intercept is a point when x=0,

so

y=x²+2x+6=0²+2*0+6=6

y=6

So y-intercept is (0,6)

so

y=x²+2x+6=0²+2*0+6=6

y=6

So y-intercept is (0,6)
