The diameter of a circle is 35.7 yards. The circle's circumference is about ___ yards.
Use 3.14 for .
Answers
Answer:
I think the answer is 112.098 yards
Answer:
112 yards
It's 112.098, but the question says "about _____ yards", so I'd round it.
Step-by-step explanation:
Circumference is calculated by (2)(pi)(radius) or (pi)(diameter). We'll use the second one, since they gave you the diameter.
C = (pi)(diameter)
C = (3.14)(35.7)
C =112.098

Given:
The height of the triangular prism is 15 cm.
The side lengths of the base are 3 cm, 4 cm and 5 cm.
To find:
The lateral surface area of the prism.
Solution:
The lateral surface area of the prism is:
[tex]LSA=Ph[/tex]
Where, P is the perimeter of base and h is the height of the prism.
We know that the perimeter of base is the sum of all sides of the base.
The perimeter of the prism is (3+4+5) cm and the height of the prism is 15 cm.
So, the lateral surface area of the prism is:
[tex]LSA=(3+4+5)\times 15[/tex]
[tex]LSA=(12)\times 15[/tex]
[tex]LSA=180[/tex]
Therefore, the lateral surface area of the prism is 180 square cm.

Resh's gross pay is $1300 per fortnight. Fortnightly deductions from her gross pay are: PAYE: $31.85 FNPF: 5% HEALTH INSURANCE: $20.50 calculate her fortnightly net pay??
Answers
Answer:
$1182.65
Step-by-step explanation:
Given :
Fortnight gross pay = $1300
Given :
PAYE: $31.85 FNPF: 5% HEALTH INSURANCE: $20.50 calculate her fortnightly net pay
FNPF = 5% = 0.05 * $1300 = $65
PAYE = $31.85 ; HEALTH INSURANCE = $20.50
Total deduction = $(65 + 31.85 + 20.50) = $117.35
Net pay :
Gross pay - deduction
$1300 - $117.35 = $1182.65

Answers
Answer:
x=2
Step-by-step explanation:
Hi there!
Whenever we're solving an algebraic equation, our goal is always to isolate the variable, which in this case is x. We would do this by performing inverse operations on both sides of the equal sign to cancel values out.
[tex]10-2x + 3 = 5x-9 + 4x[/tex]
Combine like terms on both sides of the equal sign
[tex]10+ 3-2x = 5x+ 4x-9 \\13-2x = 9x-9[/tex]
Add 2x to both sides to cancel out -2x (addition is the inverse of subtraction)
[tex]13-2x +2x = 9x-9 +2x\\13 = 11x-9[/tex]
Add 9 to both sides to cancel out -9 and isolate 11x (addition is the inverse of subtraction)
[tex]13+9 = 11x-9+9\\22=11x[/tex]
Divide both sides by 11 to isolate x (division is the inverse of multiplication)[tex]\frac{22}{11} =\frac{11x}{11} \\2=x[/tex]
Therefore, x=2.

Answer:
RS = 19
Step-by-step explanation:
Given a segment joining the midpoints of 2 sides of a triangle then it is half the length of the third side, that is
- 5x + 44 = [tex]\frac{1}{2}[/tex] (18 + 4x) ( multiply both sides by 2 to clear the fraction )
- 10x + 88 = 18 + 4x ( add 10x to both sides )
88 = 18 + 14x ( subtract 18 from both sides )
70 = 14x ( divide both sides by 14 )
5 = x
Then
RS = - 5x + 44 = - 5(5) + 44 = - 25 + 44 = 19

Answer:
$318
Step-by-step explanation:
Calculation to determine the predicted end-of-year value of a portfolio
Given expression 1.08s + 1.02b
Now let determine the Predicted end-of-year value
Predicted end-of-year value=1.08(200) +1.02(100)

I used Pythagoras Theorem to find the diagonal distance as placement of objects is right angles triangle.
[tex] {c}^{2} = {a}^{2} + {b}^{2} [/tex]
a : Elm street

c : Diagonal distance
c^2 = a^2 + b^2
c^2 = 15^2 + 8^2
c^2 = 225 + 64
c = √289
c = 17 blocks
I added the total distance of the original route Joline took

How much less distance does she have to walk if she took the diagonal route

The figure has been decomposed into 3 rectangles as shown in the attachment. Therefore:
Area of the figure = area of rectangle 1 + area of rectangle 2 + area of rectangle 3
✔️Area of rectangle 1:
Area = L*W
L = 2 m
W = 4 m
Area = 2*4 = 8 m²
✔️Area of rectangle 2:
Area = L*W
L = 4 m
W = 6 - 4 = 2 m
Area = 4*2 = 8 m²
✔️Area of rectangle 3:
Area = L*W
L = 10 m
W = 6 m
Area = 10*6 = 60 m²
✅Area of the figure = 8 + 8 + 60
