Answer:
Step-by-step explanation:
Let number be "n".
Half a number added to the number = 240
This means
0.5n + n = 240
1.5n = 240
Divide both sides by 1.5
n = 240/1.5 = 160

In an obstacle course, participants climb to the top of a tower and use a zip line to travel across a mud pit. The zip line extends from the top of a tower to a point on the ground 60 feet away from the base of the tower. The angle of elevation of the zip line is 20°. Estimate the length of the zip line to the nearest tenth of a foot.
about 63.9 ft
about 21.8 ft
about 175.4 ft
about 164.8 ft
Using relations in a right triangle, it is found that the length of the zip line is of about 63.9 ft.
What are the relations in a right triangle?The relations in a right triangle are given as follows:
The sine of an angle is given by the length of the opposite side to the angle divided by the length of the hypotenuse.The cosine of an angle is given by the length of the adjacent side to the angle divided by the length of the hypotenuse.The tangent of an angle is given by the length of the opposite side to the angle divided by the length of the adjacent side to the angle.In this problem, the hypotenuse is the length of the line, considering that the base of 60 ft is adjacent to the angle of 20º, hence:
[tex]\cos{20^\circ} = \frac{60}{l}[/tex]
[tex]l = \frac{60}{\cos{20^\circ}}[/tex]
[tex]l = 63.9[/tex]
The length of the zip line is of about 63.9 ft.

cylinder has a base diameter of 6m and a height of 12m. What is its volume in cubic m, to the nearest tenths place
Answer:
339.3m²
Step-by-step explanation:
Formula is volume= X radius² X height
First find radius, which is 1/2 of the diameter. 6/2= 3 is the radius
Then set up the equation: ()(3²)(12)
Put into calculator to get 339.3 (rounded to the tenths)
The volume of the cylinder will be 339.12 cubic meters.
What is the volume of a right circular cylinder?Let r be the radius and h be the height of the cylinder. Then the volume of the cylinder will be given as,
V = π r²h cubic units
The cylinder has a base diameter of 6 m and a height of 12 m. Then the radius of the cylinder is calculated as,
r = d / 2
r = 6 / 2
r = 3 m
Then the volume of the cylinder is calculated as,
V = 3.14 x 3² x 12
V = 339.12 cubic meters

Answer:
32 Black grapes
Step-by-step explanation:
The ratio is 3:4 meaning that for every 3 green grapes, there are 4 black grapes
If there were 6 green grapes there would be (4/3)*6 black grapes, thus, 8 grapes
In this case, we have 24 green grapes, simply apply this ratio to find the black grapes;
(4/3)*24 = 32

Given that,
The equation is (1/3-6m)-(1/4n-8)
We have to find the difference of the equation.
What is difference?
Difference in mathematics is produced by one of the most important mathematical operations, which is obtained by deleting two numbers. It displays the difference between two numbers. To determine how many numbers are between the two supplied numbers is the goal of finding the difference in math.
The difference in mathematical notation is minus (-).
To difference between whole numbers and natural numbers, take the following steps:
The values are initially arranged vertically according to their place values. Additionally, make sure that the larger number is on top and the smaller one is at the bottom.
Starting at the ones place, begin removing the numerals.
Take the equation,
(1/3-6m)-(1/4n-8)
Taking least common multiple.
(1-6×3m)/3-(1n-8×4)/4
By multiplication
(1-18m)/3-(n-32)/4
Taking the least common multiple.
4(1-18m)-3(n-32)/3×4
By multiplication
(4-72m-3n+96)/12
Now by adding
(-72m-3n+100)/12
By dividing
-6m-1/4n+25/3
Therefore, The difference of the equation is -6m-1/4n+25/3.

At the same rate, how long would it take him to drive 325 miles?
Answer:
5 hours
Step-by-step explanation:
time per mile = number of hours ÷ number of miles
= 13 ÷ 845
= 1/65 hours per mile
time to drive 325 miles = 325 × time per mile
= 325 × 1/65

The basketball team earned $215 by washing cars. They want to buy basketballs that cost $39 each. How many can the team buy?
Answer:
The team can buy 5 basketballs
Step-by-step explanation:
215 / 39 = 5.51
or
5 with a remainder of 20 dollars.
We simply cannot buy 0.51 of a basketball, unless you bring a saw...
Answer:
they can buy 5 balls, and they will have 20 dollars left over.
Step-by-step explanation:
to solve, divide 215 by 39, so 215/39 which gives us 5.512. and since we cant have half of a ball, and we do not have enough capital to buy another ball, we settle for the 5. it isnt important, but to get the leftover money, just multiply 5 by 39, or 5x39 to get 195. then subtract the original value to get 20 dollars.
