This figure consists of a rectangle and semicircle.
What is the area of this figure?
Use 3.14 for π.
Enter your answer as a decimal in the box.
___ ft²
Answer:
Radius of semicircle = 2 ft
Area of semicircle = 0.5πr² = 0.5π2² = 6.28 sq ft
Area of rectangle = 10 × 4 = 40 sq ft
Total area = 46.28 sq ft
Johnny printed two maps of a walking trail near his home. The length of the walking trail on the first map is 8 cm. (THIS QUESTION HAS 3 PARTS)
Part A.) Choose a length between 5cm and 15cm for the walking trail on the second map: ________cm.
Part B.) Determine the scale factor from the first map to the second map. Show your work. It may help you to “draw” out the two maps and label the trails and their corresponding lengths. (2 points)
Scale factor =
Part C.) A landmark on the first map is a triangle with side lengths of 3 mm, 4 mm, and 5 mm. What are the side lengths of the triangle landmark on the second map? Show your work. It may help you to “draw” out the two maps and label the trails. (3 points)
Answer:
Scales are used on maps in the same way that they are used in plans.
A scale of 1 : 50 000 is used on many Ordnance Survey maps.
This means that 1 cm on the map represents an actual distance of 50 000 cm (or 500 m or 0.5 km).
Converting measurements on a map
We saw above that if a map has a scale of 1 : 50000, then 1 cm on the map is 50000 cm in real life.
(a) Imagine we have measured a distance as 3 cm on this map, and we want to find out how far this is in real life.
To work out the distance in real life, we need to multiply this length by 50000.
This gives 3 cm × 50000 = 150000 cm which is 1500 m or 1.5 km.
Alternatively, we could have just remembered that each 1 cm on the map is 0.5 km in real life.
Hence, 3 cm on the map must be 3 × 0.5 km = 1.5 km in real life.
(b) Now imagine we want to walk 4.5 km in real life, and we need to find out how far this is on the map.
To work out the distance on the map, we need to divide this length by 50000.
4.5 km = 4500 m = 450000 cm. Dividing 450000 cm by 50000 gives a distance on the map of 9 cm.
Alternatively, we could have just remembered that each 0.5 km in real life is 1 cm on the map.
If we divide 4.5 km by 0.5 km we get 9, so the distance on the map must be 9 cm.

Answer:
H (20) = E
380
Step-by-step explanation:
So, Rana is trying to multiply her hours with her earnings to get the product, that's where the variable E is. H stands for hours, and so you will multiply it by 20 because that's how much she gets per hour.

The grid below is in the shape of a rectangle.
What is the area, in square units, of the shaded part of the rectangle?
A. 14
B. 24
C. 28
D. 48
Answer:
B. 24
Step-by-step explanation:
The shaded area of the rectangle is 24 square units. Therefore, option B is the correct answer.
What is the area of a triangle?The area of a triangle is defined as the total space occupied by the three sides of a triangle in a 2-dimensional plane. The basic formula for the area of a triangle is equal to half the product of its base and height, i.e., A = 1/2 × b × h.
From the given figure,
Height of a triangle is 8 units and the base of the triangle is 6 units.
Here, area = 1/2 ×6×8
= 24 square units
Therefore, option B is the correct answer.

i don't understand this one plz help before sunday.(Thank may God bless you and back the blue)
Answer:
2/3(3/4x-3/2) = 1/2x-1
(2x+1) - (x+3/2) = x - 1/2
Step-by-step explanation:
1) Distribute 2/3 to both 3/4x and -3/2
2/3(3/4x) = 6/12x which can be simplified as 1/2x
2/3(-3/2) = -6/6 which simplifies to -1
2/3(3/4x-3/2) = 1/2x-1
2) (2x+1) - (x+3/2) combine like terms
2x-x = x
1 - 3/2= 1- 1 1/2 ( change 3/2 into an improper fraction. 2 goes into 3 one time with one left over. Place the “leftover” back on top of the original denominator of 2)
1- 1 1/2 = -1/2, so
(2x+1) - (x+3/2) = x - 1/2
Write a linear expression in the simplest form to represent the perimeter of the triangle at the right. Then find the perimeter if the value of x is 10 millimeters
Answer:
P= 22x+10 7x+9x+6x+8+6-4 = 22x+10
when x=10, 22(10)+10=230mm

The formula to find the surface area (S) of a rectangular prism with a length (l), a width (w) and a height (h) is:
S = 2lw + 2wh + 2lh
What is the surface area, in inches, of a rectangular prism with a length of 5, a width of 4, and a height of 6?
Answer:
148 in^3
Step-by-step explanation:
S= 2lw + 2wh + 2lh
S = (2 x 5 x 4) + (2 x 4 x 6) + (2 x 5 x 6)
S = 40 + 48 + 60
S = 148

Oscar spent two thirds hour each night doing homework for five nights this week. How many hours of homework did Oscar complete this week?
seven and one half hours
three and one third hours
two and one third hours
one and one fifth hours
Answer:
The answer is 7.5 hours.
Step-by-step explanation: This is because if he spent 2/3 of every night doing homework for five days then he would spend a lot more than 3 hours and the other answers are even below 3 so thats gotta be incorrect.
Hope this helps.
Answer:
The answer is three and one third hours
Step-by-step explanation:
If Oscar spent two thirds an hour for five nights doing homework, then we would have night one is two thirds, the next night he spent one and one third, the next night would be 2 hours total, then the next night would add another 2/3 making it 2 2/3, finally the last night is two thirds of an hour making it a total of 3 and 1/3 hours spent on homework that week.

Answer:
65°
Step-by-step explanation:
the angle of a straight line has to add up to 180°
if it doesn't, it's not a straight line
115° and x are supplementary angles
meaning we know they have to add up to 180°
so simply subtract
180- 115 =
65°
you can check work by adding
115+65= 180
Answer: 65
180-115=65
Step-by-step explanation:
A straight line is always 180 so I subtracted 115 from 180.
