Buckets of cement needed is 5 and sand needed is 20
Solution:
Given that Concrete tiles are made using buckets of cement, sand and gravel mixed in the ratio 1 : 4 : 6
cement : sand : gravel = 1 : 4 : 6
Let the cement needed be "1x"
Let the sand needed be "4x"
Let the gravel needed be "6x"
Given that 20 buckets of sand used
4x = 20
x = 5
Thus buckets of cement needed = 1x = 1(5) = 5
Buckets of sand needed = 4x = 4(5) = 20
5 buckets of cement and 20 buckets of sand are needed

A bike tire has a diameter of 35 inches. If the tire rotates 10 revolutions, how far did the bike travel?
Answer:
Distance travelled = 91.61 feet
Step-by-step explanation:
Given the following data;
Diameter, d = 35 inches
Number of revolutions = 10 Rev
To find the distance travelled by the bike;
First of all, we would determine the circumference of the bike's tire, which is circular in shape.
Circumference of circle = πd
Circumference of circle = 35π
Next, we multiply by the number of revolutions to get the distance travelled.
Distance travelled = 35π * 10
Distance travelled = 350π inches
But pie, π = 3.142
Distance travelled = 350 * 3.142
Distance travelled = 1099.7 inches.
In feet;
1 inches = 0.0833 feet
1099.7 inches = x feet
Cross-multiplying, we have;
x feet = 1099.7 * 0.0833
x feet = 91.61 feet
Distance travelled = 91.61 feet

To find the height of a pole, a surveyor moves 121 feet away from the base of the pole and then, with a transit 3.6 feet tall, measures the angle of elevation to the top of the pole to be 39. To the nearest foot, what is the height of the pole? Round your final answer to the nearest tenth of a foot.
Answer: 139 feet
Step-by-step explanation:I used tan. Tan(44) = x/140
x = 140(Tan 44)
x = 135.196
The transit is 4, so we add that to 135.
This makes 139 feet.

4x + 33 / 9 = -9
Answer:
4x + 33 / 9 = -9
multiply both side by 9;
9x(4x + 33 / 9 )= -9 x(9)
36x + 33 =-81
36x = -81-33
36x = -114
x = (-114)/36
Step-by-step explanation:
Answer:
4x+33/9= -9 (reduce the fraction)
4x+11/9= -9 (move the constant to the.
right)
4x = -9- 11/9
4x = -38/3 (divide both sides by 4)
x = -19/6

Which equation represents a line which is parallel to x=0?
y=5
x=4
x=1/4y
x=−4y
Answer:Answer is A
Step-by-step explanation:
Correct option is
A
6x+2y=15
Given line is y=−3x+4
This is slope intercept form of a line where slope of line is −3.
Since, two lines are parallel When their slopes are equal.
Slope of line is 6x+2y=15
⇒2y=−6x+15
⇒y=−3x+

15
is equal to −3

What is Mortgage Rate?A mortgage rate is the interest rate on a mortgage. Mortgage rates are set by the lender and might be fixed, remaining constant during the length of the loan, or variable, varying with a benchmark interest rate. Borrowers' mortgage rates differ depending on their credit profile.
We have,
P = $105, 000
T = 40 year
R = 5.2%
Using
Monthly payment, P = C[i(1+i[tex])^n[/tex]]/[(1+i[tex])^n[/tex]-1]
P = 105,000 [ 0.052/12(1+0.052/12[tex])^{480[/tex]]/[(1+0.052/12[tex])^{480\\[/tex]-1]
P = 105,000 [ 0.00433 (7.8426)] / [7.8426 -1]
P = 105,000 [ 0.03372318] / (6.8426)
P = $249,739

What is the percent of change from 800,000 to 80,000?
Solution for 80000 is what percent of 800000:
80000:800000*100 =
(80000*100):800000 =
8000000:800000 = 10

At a certain fire station, false alarms are received at a mean rate of .2 per day. In a year, what is the probability that fewer than 60 false alarms are received?
Answer:
0.064
Step-by-step explanation:
Number of days in a year = 365
Mean rate of false alarm in a year = λ = 365 * 0.2 = 73
Standard deviation, σ = sqrt(λ) = sqrt(73) = 8.54 (for large λ value)
Using the relation :
P(x < 60): (60 - 73) / 8.54
P(x < 60) = - 1.52
P(Z < - 1.52) = 0.06426 (Z probability calculator

In the example, what is the relationship between the perimeter and the side length of an equilateral triangle
Answer:
P = 3s
Step-by-step explanation:
To start with, let's assume that
The perimeter of a triangle is called P
The side of a triangle is called s
Now, by formulae, the perimeter of an equilateral triangle is given as P = 3s. Which is the same as adding up the 3 sides together.
Succinctly put, we can then conclude that if P = 3s, then the perimeter of an equilateral triangle is equal to the lengths of its 3 sides.
