4. Brett is fencing in a circular patio. The radius of the patio is 70 feet. How many linear feet of
fencing does he need to enclose the patio?
Answer:
The number of feet of fencing that he needs will be equal to the perimeter of the circular patio.
We know that the perimeter of a circle of radius R is equal to:
P = 2*pi*R
where pi = 3.14
Then if the radius of the patio is 70ft, the perimeter of the patio will be:
P = 2*3.14*70ft = 439.6 ft
Then he needs 439.6 ft of fencing to enclose the patio.

Mrs. Smith has a total of 25 kids in her class. There are 3 more boys than there are girls. Write a system of equations to model this. Use b to represents the boys and g to represent the girls.
Answer:
b + g = 25
b = g + 3
Step-by-step explanation:
Let b = number of boys.
Let g = number of girls.
"Mrs. Smith has a total of 25 kids in her class."
b + g = 25
"There are 3 more boys than there are girls."
b = g + 3
The system of equations is:
b + g = 25
b = g + 3

Helen has to buy all the butter she needs to make 60 biscuits.
She buys the butter in 250 g packs.
b) (i) What is the exact amount of butter she needs?
g
(ii) How many packs of butter will she have to buy?
Answer:
1 pack of butter, and 360 grams flour.
Step-by-step explanation:
it just mental math, and i kinda forget how i even got the answer, but its 1 because she only needs 240 grams. and also 360 flour.
Answer:
I'll give you the correct answer:
a) You need to times 60 by 3: 60*3. This will get you 180g, which gets your first mark.
Next, you must times 180 by 4: 180*4. This gets you 720g, and there's your final answer + the last marks.
b) (i) 420g
(ii) 2 packs, because there is 240 g in one pack so you times it by two.
Hope this helps!

With reference angle A
perpendicular (p) = 6
hypotenuse (h) = 10
Then
Sin A
= p/h
= 6 / 10
= 0.6
Answer:
Option B
Step-by-step explanation:
We know that
[tex] \sin( \alpha ) = \frac{side \: opposite \: to \: \alpha }{hypotenuse \: of \: triangle} [/tex]
where [tex] \ alpha [/tex] is an angle of a triangle.
In the triangle given above , [tex] \ alpha = angle A [/tex]. So,
[tex] \sin(a) = \frac{6}{10} = 0.60[/tex]

A rectangle has a length that is 4 meters more than the width. The area of the rectangle is 117 square meters. Find the dimensions of the rectangle.
Answer choices are on picture.
Answer:
Its the first choice. Width:9 Length:13
Step-by-step explanation:
If the length is 4 meter more than the width than that means whatever the width is you must add 4 to it, in this case the width is 9 so add 4 to it which equals 13. If the length matches your answer it is the correct choice.
The area of a rectangle is the product of its dimensions. The dimension of the rectangle is: [tex]Length = 13m[/tex] and [tex]Width = 9m[/tex]
Given that:
[tex]L =4 + W[/tex]
[tex]Area = 117[/tex]
The area of a rectangle is:
[tex]Area = L \times W[/tex]
So, we have:
[tex]L \times W= 117[/tex]
Substitute [tex]L =4 + W[/tex]
[tex](4 + W) \times W = 117[/tex]
Expand
[tex]4W + W^2 = 117[/tex]
Rewrite as:
[tex]W^2 + 4W- 117 = 0[/tex]
Expand
[tex]W^2 + 13W - 9W - 117 = 0[/tex]
Factorize
[tex]W(W + 13) - 9(W + 13) = 0[/tex]
Factor out W + 13
[tex](W - 9)(W + 13) = 0[/tex]
Solve for W
[tex]W = 9[/tex] or [tex]W = -13[/tex]
The dimension cannot be negative.
So:
[tex]W = 9[/tex]
Recall that:
[tex]L =4 + W[/tex]
[tex]L = 4 + 9[/tex]
[tex]L = 13[/tex]
So, the dimension of the rectangle is:
[tex]Length = 13m[/tex]
[tex]Width = 9m[/tex]

Amirah is 4 years older than Priya and Shirley is
2 years younger than Priya. If the sum of their ages
is 47, find their respective ages.
Answer:
Priyah = 15
Amirah = 19
Shirley = 13
Step-by-step explanation:
Let A represents Amirah, P Priyah and S, Shirley.
So, we have:
[tex]A = 4 + P[/tex] --- 4 years older
[tex]S = P - 2[/tex] --- 2 years younger
[tex]A + P + S = 47[/tex]
Required
Find their ages
Substitute 4 + P for A and P - 2 for S in [tex]A + P + S = 47[/tex]
[tex]4 + P + P + P - 2 = 47[/tex]
[tex]4 + 3P - 2 = 47[/tex]
Collect Like Terms
[tex]3P = 47 - 4+ 2[/tex]
[tex]3P = 45[/tex]
Divide both sides by 3
[tex]P = \frac{45}{3}[/tex]
[tex]P = 15[/tex]
Substitute 15 for P in [tex]A = 4 + P[/tex] and [tex]S = P - 2[/tex]
[tex]A = 4 + 15[/tex]
[tex]A = 19[/tex]
[tex]S = 15 - 2[/tex]

12 inches
if the length = x,
P = 150 inches
=2 { ( 5x + 3 ) + x }
=10x + 6 + 2x
=12x + 6
Therefore 12x + 6 = 150
12x = 150 - 6
12x = 144
