Step-by-step explanation:

Each sandwich will be divided into 6 pieces. 1 sandwich equals 6 pieces, 2 sandwiches equals 12 pieces, so 3 sandwiches equals 18 pieces.

Answer:

It will be 18

Step-by-step explanation:

All you have to do is simple multiplication, 6 times 3 and you get 18

3 sandwiches and 6 pieces each.

Answer:

3200π mm³

Step-by-step explanation:

The volume (V) of the cylindrical tower is calculated as

V = πr²h ( r is the radius and h the height ) , then

V = π × 8² × 50 = π × 64 × 50 = 3200π mm³

Step-by-step explanation:

Answer:

Check explanation

Step-by-step explanation:

There are two ways to solve this, I'm not sure which way is the correct one:

1. Solving with 3.14

V=πr²h

V=(3.14)(13)²(17)

V=(3.14)(169)(17)

V=(3.14)(2873)

V=9021.22

9021.22 rounded to the nearest hundredth is 9021.22

2. Solving with π (I used a calculator to solve with π)

V=πr²h

V=π(13)²(17)

V=π(169)(17)

V=π(2873)

V=9025.79569376

9025.79569376 rounded to the nearest hundredth is 9025.8

The question says to use 3.14 so it can be method 1, but the question also asks to round to the nearest hundredth and method 2 leads me to actually being able to round so it can be suspected that method 2 is the correct way. Whichever you think is best can be chosen and sorry if this isn't a clear answer! I hope it does help.

Answer:

V=9021.22

Step-by-step explanation:

The formula for a cylinder is πr(r)(h)

r=13

h=17

π13(13)(17)

π169(17)

π2873

π=3.14

3.14(2873)

9021.22

V=9021.22

Answer:

y = 114

Step-by-step explanation:

n + x = y

n - 20 = 85

n = 105

x=9

105 + 9 = 114

Answer:

original ammount is 1/3 since tripled it is 1 cup

the improper fraction is 4/3 since you find a improper fraction by using these steps- Convert the mixed number 113 1 1 3 into an improper fraction first by multiplying the denominator (3) by the whole number part (1) and add the numerator (1) to get the new numerator. Place the new numerator (4) over the old denominator

Answer:

5/28

Step-by-step explanation:

-5/8 ÷ -7/2

Answer:

5 over 28

Step-by-step explanation:

Answer:

A. both coordinates are positive.

Step-by-step explanation:

I'm attaching a picture. The lower right quadrant/quarter is where x is positive and y is negative. When you "reflect over the y axis" it's mirroring the position by flipping it above the y axis.

In my picture, I used the example of a filled in dot in the lower right quadrant at +2 x, and -2 y. Right above that, in the upper right quadrant, there's an unfilled circle at +2 x, and +2 y. The second point is the first after being "reflected over the y axis." X stays the same, but the y goes from negative to positive.

I hope this helps. Please ask me if it's still confusing.

Step-by-step explanation:

the radius of a circle is half of the diameter

= 24.4/2 = 12.2 m

the area of a circle is

pi × r²

r being the radius.

so, in our case that is

3.14 × 12.2² = 3.14 × 148.84 = 467.3576 ≈ 467.36 m²

Answer:

Fish A and Fish B

Step-by-step explanation:

Fish A: 752 mm = 75.2cm

Fish B: 0.00063 km = 63cm

Fish C: 0.29 m = 29cm

They can only keep Fish A and Fish B.

Answer:

105.12 squared cm.

Step-by-step explanation:

Square:

8*8 = 64

Semi Circle:

A = pi * 4^2/2

50.24/2

25.12

Triangle:

(4*8)/2 = 16

64 + 25.12 + 16 = 105.12

Answer:4/5

Step-by-step explanation:

I think it's 4/5 because the number 3 is only one number of 5. And if you subtract 5-1, you'll get 4.

Answer:

D

Step-by-step explanation:

Everytime your X goes up by 1, your Y goes up by 4

making the space between 6 and 14 = 10

the exponential factor equation would look something like this

g(x)=3^x

meaning every time x goes up by 1, your exponential factor gets multiplied by 3, making 14y have an exponential factor of 1.

Answer:

25 un²

Step-by-step explanation:

Area of trapezoid =

1/2(4+6)*2 = 10 un²

Area Parallelogram =

1 x 6= 6 un²

Area triangle =

1/2(6x3) = 9 un²

Total area = 10 un² + 9 un² + 6 un² = 25 un²
