1: 15 - 3/7 =
2: Hayden has 5 hours to practice his oboe. It takes him 3/5 of an hour to practice one song. How many songs can he practice in 5 hours?
3: 12/15 x 6/18 =
4: 4 4/8 x 1 3/11 =
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 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
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.

Plz help will Mark Brainly A. Geographic elevation is the distance of a location above or below Earth's sea level. Laguna del Carbon has a lower
elevation than Death Valley. The Dead Sea is the lowest point of elevation on Earth. Lake Assal is higher in elevation than
the Dead Sea but lower than Laguna del Carbon. The table below shows the four elevations without the location names
Location
Elevation (feet)
-1360
-509
-344
-282
Use the given information to determine the locations which match the elevations in the table.
List the location names along with the corresponding elevation levels.
B. The lowest point of elevation in the state of Vermont is Lake Champlain at 95 feet above sea level.
Which is further from sea level, Lake Champlain or Death Valley? Explain.
C. New Orleans, Louisiana, is at an elevation of -8 feet relative to sea level.
9514 1404 393
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.

R = 18П/2П = 9 сm
Find the area of a circle with a diameter of 56 millimeters. Round your answer to the nearest hundredth.
area: about ???
mm2
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.

Answer:
The car will travel 29 1/3 miles in 44 minutes, 40 miles in an hour.
Step-by-step explanation:
First, find how far the car can travel in one minute.
(1 1/2)/(2 1/4)=(2/3)
Then multiply the amount of time in minutes.
(2/3)*44= 29 1/3
(2/3)*60=40

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

Which set of ordered pairs represents y as a function of x?
9514 1404 393
Answer:
A. {(2, -1), (4, -2), (6, -3), (8, -4)}
Step-by-step explanation:
A set of ordered pairs that is a function will have no repeated x-values.
Here, the x-values are ...
a) {2, 4, 6, 8} . . . no repeats, a function
b) (0, 1, 1, 2} . . . 1 is repeated; not a function
c) {3, 3, 4, 4} . . . 3 and 4 are repeated; not a function
d) {1, 1, 2, 2} . . . 1 and 2 are repeated; not a function
The first of the listed choices represents y as a function of x.
Solve:
7/8 - (-1/8)
A. -1
B. -1/8
C. 1/8
D.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!
