17. 10 · 6 = 4w 18. 180° - S = 65°
Answer:
17. w = 15 18. S = 115°
Step-by-step explanation:
17. 10 · 6 = 4w
combine like terms:
=> 60 = 4w
divided by 4 on both sides:
=> w = 15
18. 180° - S = 65°
subtract 180° on both sides:
=> -S = -115° => S = 115°

What is the height of a cone that has a volume of 90m³ and has a radius of 3.5 m?
The answer is 7.02.
This is because pi×r^2×h/3
h=3 90/3.14×3.5^2=7.01581m
Answer:
h = 7.02 m
Step-by-step explanation:
Volume of a cone = ⅓ × πr²h
h = 3 × V/πr²
= 3 × 90/3.14×(3.5)²
≈ 7.015.. m
≈ 7.02 m
A peanut butter cookie recipe calls for 3 1/2 cups of flour to make 6 dozen cookies. How many cups of flour must be used to make 20
Complete Question
A peanut butter cookie recipe calls for 3 1/2 cups of flour to make 6 dozen cookies. How many cups of flour must be used to make 20 dozen?
Answer:
11 2/3 cups of flour
Step-by-step explanation:
From the above question:
6 dozen = 3 1/2 cups of flour
20 dozen = x
Cross Multiply
6 dozen × x = 20 dozen × 3 1/2 cups of flour
x = 20 dozen × 3 1/2 cups of flour/6 dozen
x = 20 × 7/2 /6
x = 140/2 ÷ 6
x = 140/2 × 1/6
x = 140/12 cups of flour
x = 11 8/12
= 11 2/3 cups of flour
Therefore, 11 2/3 cups of flour must be used to make 20 dozen.

The graph of the quadratic parent function was transformed to create the graph g(x) = f(x) - 9. Which statement about the graphs is true?
Answers Choices
A The graph of g is a reflection of the graph of f across the x-axis.
B. The vertex of the graph is 9 units to the right of the vertex of the graph of f
C. The graph of g is a reflection of the graph of f across the y-axis.
D. The y-intercept of the graph of g is 9 units below the y-intercept of the graph of f.
9514 1404 393
Answer:
D. The y-intercept of the graph of g is 9 units below the y-intercept of the graph of f.
Step-by-step explanation:
Subtracting 9 from the function value moves every point on the graph down 9 units. That includes the y-intercept.
D. The y-intercept of the graph of g is 9 units below the y-intercept of the graph of f.

Samuel ate
1/2 of the oatmeal cookies and 2/3 of the
sugar cookies for a total of 18 cookies. The number
of oatmeal cookies he ate was six more than the
number of sugar cookies he ate. How many sugar
cookies did he eat?
Answer:
9 sugar cookies
Step-by-step explanation:
Let the number of sugar cookies be x.
If the number of oatmeal cookies was six more than the number of sugar cookies, then oatmeal cookies can be represented by x + 6.
So, we know that Samuel ate half of the oatmeal cookies and 2/3 of the sugar cookies, for a total of 18 cookies. Let's represent this with an equation.
x + x + 6 = 18
2x + 6 = 18
2x = 12
x = 6
So x represents 6. Recall that he ate 2/3 of the sugar cookies, so 2 parts of sugar cookies is 6.
Therefore, we can do this:
(3/2) x 6 = 9 cookies
This is essentially saying, "I want to find 3 parts if 2 parts is 6 cookies."
He ate 9 sugar cookies.

_2. You have a part-time job 4 days per week, 5 hours per day. How many hours will you work in two weeks?
A) 10
B) 20
C) 40
D) 80
Answer:
C) 40
Step-by-step explanation:
For every one day your work is 5 hours.
1 day = 5 hours
Set up a proportion so it would be:
[tex]\frac{1 day}{5 hours} = \frac{4 days}{x hours}[/tex]
4 days x 5 hours = 20 hours/week
So now you know you know you work 20 hours/week, then multiply by 2 since they're asking how many hours will you work in two weeks:
20 hours x 2 weeks = 40 hours in two weeks

Simon wants to earn as many points as possible in one turn in a game. Two number cubes whose sides are numbered 1 through 6 are rolled. He is given two options for the manner in which points are awarded in the turn. OPTION A: If the sum of the rolls is a prime number, Simon receives 15 points. OPTION B: If the sum of the rolls is a multiple of 3, Simon receives 12 points. Which statement best explains the option he should choose?
Answer:
The answer is "Option A"
Step-by-step explanation:
In point A:
Rolling an indivisible prime number:
The 2 can be moved just 1 way (1,1)
The 3 can be moved two different ways (1,2) or (2,1)
The 5 can be moved four different ways (1,4) or (2,3) or (3,2) or (4,1)
The 7 can be moved six different ways (1,6) or (2,5) or (3,4) or (4,3) or (5,2) or (6,1)
The 11 can be moved two different ways (5,6) or (6,5)
There are 26 approaches to move two dice at a time.
The likelihood of rolling an indivisible number is: [tex]=\frac{(1 + 2 + 4 + 6 + 2)}{36} =\frac{15}{36}[/tex]
Because rolling an indivisible number is worth 15 focuses, the normal worth is [tex](\frac{15}{36}) \times 15 = 6.25[/tex]
In point B:
When the rolling is a numerous of 3:
The 3 can be moved two different ways (1,2) or (2,10
The 6 can be moved five different ways (1,5) or (2,4) or (3,3) or (4,2) or (5,1)
The 9 can be moved four different ways (3,6) or (4,5) or (5,4) or (6,3)
The 12 can be moved just 1 way (6,6)
The likelihood of rolling a numerous of 3 will be:[tex]= \frac{(3 + 6 + 9 + 12)}{36} = \frac{12}{36}[/tex]
because the rolling in the various of 3 is worth 12 focuses, the normal worth is[tex](\frac{12}{36}) \times 12 = 4[/tex]

Those who have taken the Algebra EOC please answer.
Was it easy? What were the hardest parts? What should i study more to pass it?
Step-by-step explanation:
To me yes.
Algebra is mostly memorization. If you know the formulas and know how to apply it, you should do good.
I say use this. Algebra topics are like building on top each other.
Heart of Algebra:
Review what the purpose of x in algebra.Then learn things like combining like terms, and solving for x.Since you know the basics of x, you can then review linear equations( imo, a big content of algebra). Stuff like slope, different linear forms, graphs of linear equations, and mostly linear equation word problemsThen you can review system of equations. since you know how to manipulate linear equations, etc.Then move on to other algebra topics dealing with algebra like
functions, and different types of themexponents, and radicals rulesinequalities.sequences.These aren't the heart of algebra but study them they are useful and it important to know them.Since you learned different function rules, we can move on to learning exponetial functions, graphs, and word problems.
Then finally, learn most hard thing in Algebra: Quadratics.
Pratice,practice, and practice and you will pass.
Try to memorize the formulas and know when to apply it.
Good Luck

Dans un magasin de sport, une paire de chaussures coûte 69,30 €, après une remise de 30 %. Quel était le prix initial (avant la remise) de cette paire de chaussures ?
Answer:
€99
Step-by-step explanation:
The computation of the original price (before the rebate) of this pair of shoes is shown below:
Given that
The cost of pair of shoes is € 69.30 i.e. after 30% discount
So, the original price would be
= € 69.30 × 100 ÷ 0.70
= €99
The € 69.30 shows the 70% value according to this we determine 100% value
