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]

EASY WORK!!! Please look at the picture and yes it’s easy for other people but not for me .
Answer:
#8 ---> 1/4 2/5 1/2 3/5
#9 ---> 6 3/8 6 1/2 6 3/4 6 5/6
#10 ---> 1.75 feet is the longest
the other lengths are 1.58 ft. and 1.67 ft.
Step-by-step explanation:
good luck!
it's easy if you turn them into decimals.
to do that, you just divide the numerator (top number) by the denominator (bottom number).
e.i. 1/4= .25 (25%)
1/2= .5 (50%)
3/5= .6 (60%)
Answer:
8. 1/4, 2/5, 1/2, 3/5
9. 6 3/8, 6 1/2, 6 3/4, 6 5/6
10. the length of the longest bar is 1.75 feet
Step-by-step explanation:
(just convert all the fractions to decimal, it will be easier for you to do!)
8.
3/5 = 0.6
1/4 = 0.25
1/2 = 0.5
2/5 = 0.4
9.
6 3/4 = 6.75
6 1/2 = 6.5
6 5/6 = 6.83
6 3/8 = 6.375
10.
1 7/12 = 1.583
1 2/3 = 1.6 or 1.7

FIND THE MEASURE OF ANGLE F PLS HELP ASAP!
Answer:
We know that the sum of the the interior angles of a quadrilateral is 360°.
In the figure, angle H = angle F
angle H+ angle F+ angle E+ angle G =360°
[tex]x + x + 87 + 31 = 360 \\ 2x + 118 = 360 \\ 2x = 242 \\ x = \frac{242}{2} \\ \boxed{x = 121}[/tex]
Therefore, Angle F = 121°.
Determine whether a triangle can be formed with the given side lengths. If the side lengths
can form a triangle, determine if they will form an isosceles triangle, equilateral triangle, or
neither.
2 mi, 4 mi, 9 mi
Answer:
it can't form isosceles triangle cause any two sides of the triangle are not equal ,it can't form equalateral triangle cause 3 sides of the triangle are not equal and neither right angle triangle so triangle can't be formed
PLZ HALP!!!!! the length of a rectange is 1 7/9 inches, and its width is 3/4 of its length. find the area of this rectangle.
9514 1404 393
Answer:
2 10/27 square inches
Step-by-step explanation:
The length is 1 7/9 = 16/9 inches. The width is 3/4 of that, so is ...
(3/4)(16/9) = 4/3 inches
The area is the product of length and width, so is ...
A = (16/9 in)(4/3 in) = 64/27 in²
The area of the rectangle is 2 10/27 square inches.
Which product shows the decimal placed correctly?
1.4 x 1.5
A) 210
B) 21
C) 2.1
D) 0.21

Evaluate w divided by z if w= 6/7 and z= 3
Answer:
[tex]\dfrac{w}{z}=\dfrac{2}{7}[/tex]
Step-by-step explanation:
Given that,
[tex]w=\dfrac{6}{7}[/tex]
z = 3
We need to find [tex]\dfrac{w}{z}[/tex].
Put w = 6/7 and z = 3 in the w/z
[tex]\dfrac{w}{z}=\dfrac{\dfrac{6}{7}}{3}\\\\=\dfrac{6}{7}\cdot\dfrac{1}{3}\\\\=\dfrac{2}{7}[/tex]
So, [tex]\dfrac{w}{z}=\dfrac{2}{7}[/tex]. Hence, the correct answer is 2/7.
How many bows can you make from 3 2/3 meters of ribbon if one bow takes 1/4 meter of ribbon?
Answer:
14 bows can be made from [tex]3\frac{2}{3}[/tex] meters of ribbon.
Step-by-step explanation:
Given that:
Length of ribbon available to make bows = [tex]3\frac{2}{3}[/tex] meters = [tex]\frac{11}{3}[/tex] meters
Ribbon used to make 1 bow = 1/4 meter
Let,
x be the number of bows made.
[tex]\frac{1}{4}x=\frac{11}{3}[/tex]
Multiplying both sides by 4
[tex]4*\frac{1}{4}x=\frac{11}{3}*4[/tex]
x = [tex]\frac{44}{3}[/tex]
x = 14.66
As the number of bows cannot be in decimal.
Hence,
14 bows can be made from [tex]3\frac{2}{3}[/tex] meters of ribbon.

Deanna is having a party she estimates for that she will need 3 slices of pizza for each guest and 8 extra slices for unexpected guest.
Write an equation that relates the total slices of pizza, T, to the number of guest, g.
Thanks
Answer:
3g + 8 = T
Step-by-step explanation:
3g + 8 = T because since Deanna estimates 3 slices for each guest, you would times the # of guests by 3, which is 3g. Then you would add 8 because Deanna will need extra 8 slices for the unexpected guests. This equation would tell you how many slices Deanna needs in total.
Hope this helps :D

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.
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.

what represents the quantitative forecast
Answer:
Quantitative forecasting relies on data that can be measured and manipulated. The data is usually from the past. This type of analysis is best for short-term forecasting as making assumptions about the future based on past performance is much more likely to be accurate in the near future.
