Answers

Answer:

( I am assuming that these are all fractions)

1. 14 [tex]\frac{4}{7}[/tex]

2.  8

3. [tex]\frac{4}{15}[/tex]

4. 5 [tex]\frac{8}{11}[/tex]

Step-by-step explanation:

1. First you have to convert 15 into a fraction but it must have the same denominator causing the equation to look like 105/7 - 3/7= 102/7. But you cannot just leave the fraction like that it must be simplified 14 [tex]\frac{4}{7}[/tex]

2. Three-fifths of an hour is 36 minutes. You would next multiply 5 by 60 which would the hours into minutes 5 x 60 = 300. You would then divide 300 by 36 which would give you 8.3333333333, which I just simplified it to 8

3. In order for you to multiply a fraction you would first multiply the top then the bottom. 12 x 6= 72, 15 x 18= 270. The fraction would look like 72/270 which is simplified to [tex]\frac{4}{15}[/tex] .

4. First I changed the fractions into improper fractions causing the fraction to look like 36/8 x 14/11 (I got these answers by 8 by 4 then adding 4, then for the next fraction I multiplied 11 by 1 then added 3.) 36 x 14= 1224, 11 x 8= 88 the fraction would look like 1,224/88 you would simplify to 5 [tex]\frac{8}{11}[/tex]

Hope this helps

If the diameter of a circle is 12, what is the area and circumference?

Answers

Answer:

circumference: 37.7

area: 113.1

Step-by-step explanation:

for the future look up '___ of a circle'

and enter the radius (if u are given the diameter divide it by 2)

Answer:

circumference = 37.68 (37.7 if you're rounding it)

Area = 113.04 (113.1 if you're rounding it)

Step-by-step explanation:

The formula for circumference is C=2πr (2 times pi times radius)

If the diameter is 12, the radius is 6.

2 x 3.14 x 6 = 37.7

The formula for area is A=πr2 (pi x radius to the second power)

The radius is 6. Six to the second power is 36.

36 x 3.14 = 113.04

Answer:

  A. -1360 Dead Sea; -509 Lake Assal; -344 Laguna del Carbon; -282 Death Valley

  B. Death Valley is farther

Step-by-step explanation:

A. We have the following information:

  Dead Sea is lowest

  Laguna del Carbon is lower than Death Valley

  Lake Assal is lower than Laguna del Carbon

So, the match between elevations and locations is ...

-1360 Dead Sea-509 Lake Assal-344 Laguna del Carbon-282 Death Valley

__

B. Lake Champlain is 95 feet from sea level; Death Valley is 282 feet from sea level. Death Valley is farther from sea level.

Answers

9514 1404 393

Answer:

  2463.01 mm²

  2461.76 mm² if you use 3.14 for π

Step-by-step explanation:

The formula for the area of a circle is ...

  A = πr²

where r is the radius, half the diameter.

For a diameter of 56 mm, the radius is 28 mm. Using that in the formula gives an area of ...

  A = π(28 mm)² = 784π mm²

For an appropriate value of π, the area is ...

  784π mm² = 2463.00864... mm² ≈ 2463.01 mm²

For 3.14 as the value of π, the area is ...

  784(3.14) mm² = 2461.76 mm²

_____

Comment on pi

Quite often these problems expect you to use 3.14 for pi. The required answer has 6 significant digits, so the use of a 3-digit value for pi is not appropriate. Rather, the value used should be 3.141493 or even more accurate.

If Santa has an 8 ft ladder and it reaches the top while being set 2 ft from the base of the chimney, how tall is this chimney

Answers

Answer:

Step-by-step explanation:

Well if its a 8ft ladder and its being set 2ft off from the base i think the chimney is 6 ft tall cause 8-2 is 6...

The chimney measures approximately 7.75 feet tall.

What is the right triangle?

A right triangle is defined as a triangle in which one angle is a right angle or two sides are perpendicular.

To find the height of the chimney, you can use the formula for the length of the hypotenuse of a right triangle, which is:

c² = a² + b²

Where c is the length of the hypotenuse (in this case, the length of the ladder), a is the length of one of the legs (in this case, the distance the ladder is set from the base of the chimney), and b is the length of the other leg (in this case, the height of the chimney).

Plugging in the values given in the question, we get:

8² = 2² + b²

64 = 4 + b²

b² = 64 - 4

b² = 60

b = √60

b = 7.745 ≈ 7.75  

Thus, the height of the chimney is approximately 7.75 feet.

Answers

D, because two negative signs next to each other means to add so its pretty much 7/8+1/8 which equals 8/8 which also equals 1

Subtracting a negative is the same as adding a positive, since the negatives cancel each other out.

So, 7/8 - (-1/8) is the same as 7/8 + 1/8. Adding 1/8 to 7/8 gives you 8/8, or one whole, so your answer is D. 1!
