Answer:
57.75
Step-by-step explanation:
Doug did clean 1 3/4 hour.
Doug did paperwork for 2 1/3 hour
Doug did serving for 1 5/12
Add 1 3/4+ 2 1/3+1 5/12=16/12 or 5.5 hrs
In one hour Doug earns $ 10.50 .
Therefore in 5.5 hour Doug earns 5.5 $ 10.50 = $ 57.75
Hence the total which Doug earned is $ 57.75
A train travels 90 3/5 miles in 3/4 of an hour. What is the average speed, in miles per hour, of the train? I also have to show my work please help
Answer:
[tex]120 \frac{4}{5}[/tex] or 120.8 miles per hour
Step-by-step explanation:
We first convert the distance into an improper fraction to facilitate calculation.
[tex]90 \frac{3}{5} = \frac{90\times 5 + 3}{5} = \frac{453}{5}[/tex]
Average speed
= distance/time
= [tex]\frac{\frac{453}{5}}{\frac{3}{4}}[/tex]miles per hour
= [tex]\frac{453}{5} \times \frac{4}{3}[/tex] miles per hour
= [tex]\frac{604}{5}[/tex] miles per hour
= [tex]120 \frac{4}{5}[/tex] miles per hour or 120.8 miles per hour

Find the area of the Composite Shape.
PLEASE HELP!
Answer:
[tex]\large\boxed{41.14 inches^2(2 d.p)}[/tex]
[tex]\large\boxed{41.1inches^2 (1 d.p)}[/tex]
Step-by-step explanation:
Important Information:
Area of a circle= [tex]\pi r^2[/tex]
Area of a triangle= [tex]\frac{base*height}{2}[/tex]
Diameter of a cirlce= [tex]2*radius[/tex]
Method:
The first step is to divide the shape into smaller shapes. In this case, we have a right -angled triangle and a semi-circle.
The next step is to work out the area of the triangle. Since we know the radius of the semi-circle is 3 inches, to work out the diameter we would simply multiply the radius of 3 by 2, this gives us 6 inches. This is because the radius is half of the diameter.
Now that we know the diameter of the semi-cirlce, we can begin to work out the area of the triangle. We can do this by first multiplying the base of 6 inches by the height of 9 inches, this gives us 54 inches squared. This however gives us the area of 2 of those triangles. To work out the area of that triangle, we would need to divide the value of 54 by 2, this gives us 27 inches squared.
The next step is to work out the area of the semi-circle. We can do this by multiplying pi by the radius of 3, squared, this gives us 28.27 inches squared (2 d.p). However, this is for a full circle and we need to work out the area of the semi-circle. We can do this by dividing the area of the circle, which is 28.27, by 2, this gives us 14.14 inches squared (2 d.p). This is because a semi-cirlce is half of a circle.
The final step is to add the Areas of the two shapes together. You can do this by adding the area of the triangle, which is 27 inches squared, to the area of the semi circle, which is 14.14 inches squared (2 d.p), this gives us 41.14 inches squared (2 d.p).
Step by Step:
1) Multiply 3 by 2.
[tex]3*2=6[/tex]
2) Multiply 6 by 9.
[tex]6*9=54 inches^2[/tex]
3) Divide 54 by 2.
[tex]54/2=27inches^2[/tex]
4) Multiply pi by 3 squared.
[tex]\pi*3^2=28.27 inches^2 (2 d.p)[/tex]
5) Divide 28.27 by 2.
[tex]28.27/2=14.14inches^2 (2 d.p)[/tex]
6) Add 27 to 14.14.
[tex]27+14.14=41.14inches^2 (2 d.p)[/tex]

A bicycle wheel has a diameter of 62cm. The wheel makes 80 complete
revolutions.
How far has the bicycle travelled?
Give your answer in metres
Answer:
The bicycle traveled 77.9 m
Step-by-step explanation:
Circumference of a Circle
Given a circle of radius r, the circumference or perimeter is calculated as follows:
[tex]C =2\pi r[/tex]
The radius of the bicycle wheel has a radius of r=62 cm. Converting to meters r=62/100=0.62 m.
Calculate the circumference:
[tex]C =2\pi \ 0.62[/tex]
[tex]C=3.8956\ m[/tex]
Given the wheel makes 80 complete revolutions, the total distance covered by the bicycle is:
[tex]D=20*3.8956\ m[/tex]
D = 77.9 m
The bicycle traveled 77.9 m

Answer:
y<-1/3x+3
Step-by-step explanation:
The slope of this graph is -1/3 (If I read the graph correctly), from points (-3,4) and (0,3).
The graph is a y-intercept of 3, because it crosses the y-axis at 3, (0,3).
To find whether this statement is true or not, you can plug in a random point from the shaded area and test that point. (I like to use the origin, (0,0))
(0)>-1/3(0)+3 (0)<-1/3(0)+3
0>0+3 (0)<+3
0>3 0<3
The one to the right, 0<3, is true so the sign is a less than sign.
Also make sure that the line either makes a less than/ less than or equal to sign. Because the line is dashed, it makes a less than sign.

Given the following information about events A, B and C determine which pairs of events, if any, are independent and which are mutually exclusive.
P(A) = 0.26, P(A|B) = 0.26, P(B) = 0.5, P(B|C) = 0, P(C)=0.45, P(C|A) =0.26.
Select all that apply:
a. Are B and C independent?
b. Are A and C mutually exclusive?
c. Are A and B independent?
d. Are A and B mutually exclusive?
Answer:
a. Are B and C independent? NO
b. Are A and C mutually exclusive? NO
c. Are A and B independent? YES
d. Are A and B mutually exclusive? NO
Step-by-step explanation:
Given the data in the question;
P(A|B) = 0.26 P(A) [ A and B are independent ]
P(B|C) = 0 [ B and C are mutually exclusive ]
P(C/A) = 0.26 ≠ P(C)
hence, [A and C are neither independent nor mutually Exclusive]
Therefore;
a. Are B and C independent? NO
b. Are A and C mutually exclusive? NO
c. Are A and B independent? YES
d. Are A and B mutually exclusive? NO

Find the measure if two complementary angles if the measure of the larger angle is 10 more than the measure of the smaller angle.
Answer: 50° and 40°
Step-by-step explanation:
Complementary angles add up to 90°
Smaller angle - x
Larger angle - 10 + x
10 + x + x = 90
10 + 2x = 90
Subtract 10 from both sides
2x = 80
Divide both sides by 2
x = 40
Larger angle - 10 + x
10 + 40 = 50
The measure of the smaller angle is 40° and the measure of the larger angle is 50°

The measure of the trigonometric relation cos 60° = 1/2
What are trigonometric relations?Trigonometry is the study of the relationships between the angles and the lengths of the sides of triangles
The six trigonometric functions are sin , cos , tan , cosec , sec and cot
Let the angle be θ , such that
sin θ = opposite / hypotenuse
cos θ = adjacent / hypotenuse
tan θ = opposite / adjacent
tan θ = sin θ / cos θ
cosec θ = 1/sin θ
sec θ = 1/cos θ
cot θ = 1/tan θ
Given data ,
Let the trigonometric relation be represented as A
Now , the value of A is
A = cos 60°
And , cos θ = adjacent / hypotenuse
So , cos 60° = 1/2
Hence , the measure of cos 60° = 1/2

Given ΔPQR and ΔSTU, what is m∠Q?
Given that ΔPQR and ΔSTU are similar triangles, m∠Q = 64°.
Similar TrianglesThe ratios of the corresponding sides of similar triangles are always equal to each other, that is, the corresponding sides are proportional.Also, corresponding angles of two similar triangles are congruent.Thus:
ΔPQR and ΔSTU are similar because:
PQ/ST = PR/SU = QR/TU = 3.5
Therefore,
m∠Q = 180 - 70 - 46
m∠Q = 64°
Thus, given that ΔPQR and ΔSTU are similar triangles, m∠Q = 64°.

Step-by-step explanation:
Answer:
122,850 sq. ft.
Step-by-step explanation:
The area of a circle is A = πr²; since these are semi-circles, the area would be given by A = 1/2πr². Using 1/2x in place of r, we have
A = 1/2π(1/2x)² = 1/2π(1/4x²) = 1/8πx²
Using 22/7 for π, we have
A = 1/8(22/7)x² = 22/56x²
Since there are 2 semi-circles, this gives us
2(22/56x²) = 44/56x²
Simplifying this, we have
A = 22/28x² = 11/14x²
This gives us the expression
2x²+11/14x² for our expression for the area.
(Without using 22/7 for pi, we have
2x²+2(1/8πx²) = 2x²+2/8πx² = 2x²+1/4πx²
Using 210 for x and 22/7 for π, we have
A = 2(210²)+1/4(22/7)(210²) = 88200+34650= 122,850

A group of students recycled 7 2/3 pounds of glass and 9 3/4 pounds of paper. How many pounds of glass and paper did the students recycle alltogether?
Answer:
17 5/12 is the final answer
Step-by-step explanation:
First change the fractions so they have the same denominator so that would make 7 2/3 ---- 7 8/12 and 9 3/4 would become 9 9/12 then you add to get 16 17/12 which is an improper fraction so change that to 17 5/12.
