What is 1 7/8 Times 2 1\3

Answers

Answer 1

Answer: We need to convert the mixed fractions into improper fractions.

1*8 = 8
8+7 = 15

15/8

2*3 = 6
6+1 = 7

7/3

Now we can finish and multiply

$(15*7)/(8*3)$

15*7 = 105
8*3 = 24

Simplify 105/24

105/24

24*4 = 96

105 - 96 = 9

4 is the whole number, and 9 is the numerator.

4 9/24

Simplify that,

9/3 = 3
24/3 = 8

4 3/8

Answer: $4(3)/(8)$

Answer 2

Answer: 1 7/8* 2 1/3
= 15/8* 7/3
= 35/8
= 4 3/8

The final answer is 4 3/8~

The sum of 3 consecutive odd integers is 18 less than five times the middle number. Find the three integers

Answers

n, n + 2, n + 4 - three consecutive odd ntegers

n + (n + 2) + (n + 4) = 5(n + 2) - 18 |use distributive property

n + n + 2 + n + 4 = (5)(n) + (5)(2) - 18

3n + 6 = 5n + 10 - 18

3n + 6 = 5n - 8 |subtract 6 from both sides

3n = 5n - 14 |subtract 5n from both sides

-2n = -14 |divide both sides by (-2)

n = 7

n + 2 = 7 + 2 = 9

n + 4 = 7 + 4 = 11

at 9am the outside temperature was -3 degree by the noon the temperature was 12 degree a news reporter said it was getting warmer outside.why is this incorrect?

Answers

Because of wind chill, they may say that the way it feels is -3, but it was probably much warmer, but later (at 12 degrees) they were probably reporting actually temp.
This is my best guess.

Please help with this problem!!! Asap thank u so much!!!

a.
volume of a sphere is 4/3*pi*r^3
4/3*3.14*1.6^3 = 17.1486 cm^3
because it is a half sphere, divide that by 2:
8.5743 cm^3

b.
volume of a cylinder is base area (pi * r^2) multiplied by the height
The cylinder shares a radius with the half sphere, so this gives us:
3.14*1.6^2*6.2 = 49.8381 cm^3

c.
this is simply the combined volume
8.5743 + 49.8381 = 58.4124 cm^3
