O LINEAR The length of a rectangle is 6 cm longer than its width.
If the perimeter of the rectangle is 56 cm, find its length and width.
cm
Х
length: 0
width: Ich
?
cm
Answers
Answer:
I. L = 17 cm.
II. W = 11 cm.
Step-by-step explanation:
Let the length of the rectangle be L.
Let the width of the rectangle be W.
Given the following data;
Perimeter of rectangle = 56cm
Translating the word problem into an algebraic expression, we have;
L = W + 6 .....equation 1
The perimeter of a rectangle is given by the formula;
P = 2(L + W)
56 = 2(L + W) ......equation 2
Substituting eqn 1 into eqn 2, we have;
56 = 2(W + 6 + W)
56 = 2(6 + 2W)
Opening the bracket, we have;
56 = 12 + 4W
4W = 56 - 12
4W = 44
W = 44/4
W = 11 cm
Next, we would find the length of the rectangle;
From eqn 1;
L = W + 6
L = 11 + 6
L = 17 cm
Use trigonometric identities to simplify the expression.
cot(β+π)sin(β
Answers
Answer:
cosβ
Step-by-step explanation:
cot(β+π)sinβ
cot(x)=cos(x)/sin(x), so we can rewrite our expression as:
(cos(β+π)/sin(β+π)) * sinβ
sin(a+b)=sin(a)cos(b)+cos(a)sin(b), so we can rewrite our expression as:
(cos(β+π)/(sinβcosπ+cosβsinπ)) * sin(β)
cos(a+b)=cos(a)cos(b)-sin(a)sin(b), so we can rewrite our expression as:
(cosβcosπ-sinβsinπ)/(sinβcosπ+cosβsinπ)) * sin(β)
cosπ=-1 and sinπ=0, so we can rewrite our expression as:
(-cosβ)/(-sinβ) * sin(β)
(-cosβ)/(-sinβ) * sin(β)
=(cosβ/sinβ)(sinβ)
=cosβ

A circular wheel has a diameter of 42 cm. How far will it roll in 5
revolutions?
Answers
Answer:
3.142
Step-by-step explanation:
Answer:
659.75 cm
Step-by-step explanation:
First, find the circumference with the formula C = 2[tex]\pi[/tex]r
The diameter is 42 cm, so the radius will be 21 cm
Plug in the radius into the equation and solve for C
C = 2[tex]\pi[/tex]r
C = 2[tex]\pi[/tex](21)
C = 131.95
Find how far it will roll by multiplying this by 5
131.95(5)
= 659.75
So, in 5 revolutions, it will roll 659.75 cm
Estimate the perimeter and the area of the shaded figure
Show how u got it please.
Answers
Answer:
8(1 +√2)
Step-by-step explanation:
The perimeter is the sum of the sides of the figure
Taking 1 square box as 1 unit
Get the slant side using the pythagoras theorem;
l² = 2² + 2²
l² = 4 + 4
l² = 8
l =√8
Perimeter = 4(√8) + 4 + 4
Perimeter = 8 + 4√8
Perimeter = 8 + 4*2√2
Perimeter = 8 + 8√2
Perimeter = 8(1 +√2)
hence the perimeter of the shape is 8(1 +√2)

Find the circumferences of both circles to the nearest tenth.
Two circles lying one inside the other. The inner circle is shaded orange and the outer circle is shaded blue. The radius of the inner circle is labeled 5 centimeters. The distance between the outer and the inner circle is circle is labeled 5 centimeters.
The circumference of the blue circle is about
cm.
The circumference of the orange circle is about
cm
Answers
Answer:
The circumference of the blue circle is about
62.8 cm.
The circumference of the orange circle is about
31.4 cm.
Step-by-step explanation:
First the blue circle, it shows that there are 5 cm on the outside of the orange circle so the would be 5+5=10, then you add the orange circle to the 10 cm, that would give you 20 cm. Then you multiply 20 cm by pi (3.14) which will give you your answer 62.8. Do the same thing for the orange circle, 5+5=10 so 10 multiplied by pi (3.14) is 31.4

Ellie and three of her friends each bought two hamburgers and a drink at the soccer game. If the drink cost $1.25 and the total cost for all four girls was $18.20, what was the cost of a hamburger?
Answers
explanation: you have to multiply 1.25 with 4 for the drink which is 5 dollars they spent. subtract the total amount( 18.20) with the 5 dollars giving you 13.2. divide 13.2 with how many burgers they got. it says they each bought two so 4 times 2. so they got 8 burgers together. ( 13.2\ 8 = 1.65)
