Answer:
17. b. y -3 = 2/3(x +6)
18. b. y -720 = 50(x -12)
19. d. y -237,000 = 5000(x -8)
Step-by-step explanation:
The given equation is the "point-slope" equation for a line. In order to use it, you need to know a point on the line and the slope of the line. You do this math by identifying those numbers in the problem statement, then filling them into the equation.
__
17. You are given the point (x1, y1) = (-6, 3) and the slope m = 2/3. Put those in the given form:
y -y1 = m(x -x1)
y -3 = 2/3(x -(-6))
y -3 = 2/3(x +6) . . . . . . matches choice B
__
18. The intended relation is one that relate fees to months. That is, x represents months of membership and y represents fees paid. You are given a monthly rate (slope) of $50 per month, and a point (x, y) = (12, 720) -- the fee after 12 months is $720.
Putting those into the form, you have m = 50, x1 = 12, y1 = 720, so ...
y -y1 = m(x -x1)
y -720 = 50(x -12) . . . . . . . matches choice B
__
18. The table gives you several points. The x-value being used is the difference between the year number and 2005. The y-value is the profit. The point that shows up in the answer choices is the last one, (x1, y1) = (8, 237000). You have to figure the slope, but the answer choices all show its magnitude is 5000. You can tell it has positive sign because the profit increases over the years. Using this point and slope in the equation form, you get ...
y -y1 = m(x -x1)
y -237000 = 5000(x -8) . . . . . matches choice D
The slope is ...
(difference in profit)/(difference in years) = (237000 -197000)/(2013 -2005)
= 40000/8 = 5000 . . . . with a positive sign

Answer:
1330.5 cm³
Step-by-step explanation:
To find the volume you want to find the area of the circle and then times this by 14 which is the length of the shape
Area of circle = πr²
11 = the diameter so 5.5 = radius
5.5² x π = 121/4 π
times this by 14 to get 1330.464489 cm³
to 1dp = 1330.5 cm³
Answer:
1330cm³ (rounded to 3 s.f.)
Step-by-step explanation:
The formula of finding the volume of a cylinder is: [tex]\pi[/tex] × r² × h
r is the radius of the cylinder, which is also half of the diameter.
You know the diameter is 11cm and the height (h) is 14cm.
Volume of cylinder = [tex]\pi[/tex] × (11÷2)² × 14
= [tex]\pi[/tex] × 5.5² × 14
= [tex]\pi[/tex] × 30.25 × 14
= 423.5[tex]\pi[/tex]
= 1330cm³ (rounded to 3 s.f.)

I'm a bit confused because they're kinda the same thing but one of them is spaced out. I don't know if that space means anything.
Anyway if he's scores 3 more than 2 times the points ray scores, that means that he scores twice the amount that ray scores plus 3.
A cylindrical can holds 355 ml when full. The can is 12 cm tall. Work out the radius of the can to 2 decimal places.
Answers
Answer:
Radius, r = 3.06 cm
Step-by-step explanation:
Given that,
The volume of a cylinder, V = 355 mL = 355 cm³
The height of the can, h = 12 cm
We need to find the radius of the can.
The formula for the volume of a cylinder is given by :
[tex]V=\pi r^2 h[/tex]
Where
r is the radius of the can
So,
[tex]r=\sqrt{\dfrac{V}{\pi h}} \\\\r=\sqrt{\dfrac{355}{\pi \times 12}} \\\\r=3.06\ cm[/tex]
So, the radius of the can is 3.06 cm.

Answers
Complete question :
Aaron, Mathew and Sara share some money. Aaron gets 30% of the money. Mathew gets 3/8 of the money. Sara gets the rest. If Mathew gets £24 , how much do Aaron and Sara get?
Answer:
Sara = £20.8
Aaron = £19.2
Step-by-step explanation:
Let the amount of money = x
Mathew = (3/8) of x
Aaron = 30% of x = 0.3x
If (3/8)x = 24
3x / 8 = 24
3x = 192
x = £64
Aaron gets 30% = 0.3 * £64 = £19.2
Sara = £64 - (19.2 + 24)
Sara = £64 - £43.2
Sara = £20.8

In ∆ABC,

∠A = 60°∠B = 60°So, By angle sum property of triangle :
∠A + ∠B + ∠C = 180°
[tex] \tt : \implies 60\degree + 60\degree + \angle C = 180\degree[/tex]
[tex] \tt : \implies 120\degree + \angle C = 180\degree[/tex]
[tex] \tt : \implies \angle C = 180\degree - 120\degree[/tex]
[tex] \tt : \implies \angle C = 60\degree[/tex]
Now, we have :
∠A = 60°∠B = 60°∠C = 60°As, all angles are of same length, therefore it is a equilateral triangle.
We know that sides of equilateral triangle are equal.
[tex] \tt : \implies AB = BC = AC[/tex]
Now, we have BC = 12 units.
Hence, all sides are of 12 units.
Now, we know that area of equilateral triangle is :
[tex] \large \underline{\boxed{\bf{Area_{(equilateral \: triangle)} = \dfrac{\sqrt{3}}{4} side^{2}}}}[/tex]
[tex] \tt : \implies Area = \dfrac{\sqrt{3}}{4} \times (12 \: units)^{2}[/tex]
[tex] \tt : \implies Area = \dfrac{\sqrt{3}}{\cancel{4}} \times \cancel{144} \: units^{2}[/tex]
[tex] \tt : \implies Area = \sqrt{3} \times 36 \: units^{2}[/tex]
[tex] \tt : \implies Area = 36\sqrt{3} units^{2}[/tex]
So, Area of given triangle is 36√3 units².

3.86 weeks/three weeks
Step-by-step explanation:
x time it takes for thier vocab to be the same in days
so the boy lerns 360 words of spanish in a year
or 360/365 words of spanish per day which is 72/73 words per day
so,
100+4x=180+72x/73
80=288x/73-72x/73
80=216x/73
80*73=5,840
5,840=216x

What is Unitary Method?A technique to find the value of one single unit and then finding the necessary value by multiplying the single unit value
we already have $45
Need to save 175 -45 = $130
our equation will be
Let us consider , it takes x weeks to save $ 175 and we are saving $ 5 per week
45 + 5x = 175
5x = 130
x = 26
It will take 26 weeks to save a total of $ 175
Now calculating for your friend
slope of line ( observe the graph ) = y2 - y1/ x2 - x1 = 39 - 15 / 3-0 = 8
Friend already have $ 15
Money remaining = 175 - 15 = $160
let Number of weeks friend need to save be = y
per week saving =8
Using Unitary Method
8 * y = 160
y = 160 / 8 = 20weeks

bag boy for $8 per hour. Due to his class and study schedule, Nick is only able to work
up to 20 hours per week but must earn at least $150 per week. If t represents the
number of hours Nick tutors and b represents the number of hours he works as a bag
boy, which system of inequalities represents this scenario?
A. t+b = 20
15t + 8b < 150
B. t+b 20
15t + 8b = 150
C. None of the systems shown represent this scenario.
D. t+b = 20
15t + 8b > 150
Answers
Answer:The answer is B.
He can't work more than 20 hours so t+b must be less than or equal to 20.
He has to earn $150 so it cannot be less than 150. Theoretically he could earn more, e.g doing 10 hours of each job which equals $230
Therefore t + b less than or equal to 20 15t + 8b greater than or equal to 150

Te diagonals of Quadrilateral JKLM intersect at A. If KL ≅ J M , JK≅ L M and KA ≅ M A , which additional statement shows that JKLM is a rhombus?
Group of answer choices
JA = LA
JL ⊥ K M
m
KA = KJ
Answers
Answer:
JL ⊥ KM
Step-by-step explanation:
JL ⊥ KM would make the quad a rhombus because JKLM is a parallelogram since opposite sides are congruent. If the diagonals of a parallelogram are perpendicular, then the quad must be a rhombus.
JL must be perpendicular to KM because in a parallelogram if diagonals are perpendicular then the quadrilateral JKLM is a rhombus.
Given :
Quadrilateral JKLM diagonals intersect at A. KL ≅ J M , JK≅ L M and KA ≅ M AThe following steps can be used in order to determine the correct statement that shows that JKLM is a rhombus:
Step 1 - Remember a quadrilateral has four sides and the sum of the interior angles of a quadrilateral is 360 degrees.
Step 2 - According to the given data, KL ≅ JM, JK ≅ LM, and KA ≅ MA.
Step 3 - So, to make JKLM a rhombus, JL must be perpendicular to KM because in a parallelogram if diagonals are perpendicular then the quadrilateral JKLM is a rhombus.
Therefore, the correct option is B).

Find the sum of the first 33 terms of the following series, to the nearest
integer.
2,8, 14, ...
Answers
Answer:
3234
Step-by-step explanation:
The series is arithmetic with a common difference = d = 6
First we need to find the 33rd term. Use the formula [tex]a_{n} = a_{1} + (n - 1)d[/tex] where n = 33 and [tex]a_{1} = 2[/tex]
[tex]a_{33} = 2 + (33 - 1)6 = 2 + 32(6) = 194[/tex]
Now the formula for the sum of an arithmetic series is [tex]S_{n} = \frac{n(a_{1} + a_{n} )}{2}[/tex]
So, [tex]S_{33} = \frac{33(2 + 194)}{2}[/tex]
= [tex]\frac{33(196)}{2}[/tex]
= 3234
