Answer:
20 Counters
Step-by-step explanation:
Total number of counter in a bag= 200 Counters
If 50 Counters out of the total have white paint, the value is then represented as
= 50/200
=1/4
The initial 50 Counters taken out is then put in the bag again and mixed thoroughly to get an even distribution.
If 80 Counters are taken out of the bag, the value is represented as
= 1/4×80
=80/4
=20
Therefore, 20 Counters are expected to be marked with a dab of white paint.
When you add fractions is the sum always greater than 1?
Answer:
Not always
Step-by-step explanation:
Some fractions, like 1/2, if you add it with 1/2, it equals one.
Halves will always equal one, and they are fractions too, so technically not all addition of fractions are greater than 1.

F(x)=x^2 what is g(x)
Answer:
10
Step-by-step explanation:
You have to get 10 because g(x) means 5 so you multiply it by two.
Answer
The answer is (1/3x)^2
Step-by-step explanation:
g of x would equal (1/3x)^2 because if x was 6 y, g(x), would be 4
How do I calculate this parent function of a linear function? The parent function of a linear function is y=x. When the parent function is changed to y=x+5, how does the graph transform?
Step-by-step explanation:
This only moves the linear function up 5 units. So, before the y-intercept and the x-intercept both was (0,0). Now, the y-intercept is (0,5) because the graph was shifted up 5 units.

-9x+3y=-30 in slope intercept form
Answer:
y = 3x - 10
Step-by-step explanation:
Answer:
y = 3x -10
Step-by-step explanation:
Slope intercept form is y = mx+b where m is the slope and b is the y intercept
-9x +3y =-30
Add 9x from each side
-9x+9x +3y =9x-30
3y = 9x-30
Divide each side by 3
3y/3 = 9x/3 -30/3
y = 3x -10

Answer:
Q1: 48ft
Q2: 14.6
Step-by-step explanation:
Question 1:
Since the two triangles are similar (Angle - Side - Angle):
30/x = 50/80
x= 30(80/50)
=48
Question 2:
sin(55deg) = 12/x
12/sin(55) = x
x=14.6 (3 s.f.)
How do u find the unknown angle measure in a triangle
Answer:
Use the sum of angle measures rule.
Step-by-step explanation:
If you are given two angles and one missing angle, it's good to remember that all angles add up to 180°.
You can add the the given angles measurements, and subtract them by 180. You should then get the missing angle measure.

To the nearest cent, how much will he have in 2 years?
Use the formula B = p(1 + r)t, where B is the balance (final amount), p is the principal (starting amount), r is the interest rate expressed as a decimal, and t is the time in years.
Answer: $44.10
Step-by-step explanation:
We are given our p, r, t in the problem.
p=40 (starting amount)
r=0.05 (5%)
t=2 (years)
With the given information, we can plug this into our equation.
B=p(1+r)^t
B=40(1+0.05)^2
B=44.1

3(K-2)=15
How do I solve for K
Answer:
7
Step-by-step explanation:
step 1. divide 15 by 3
(K-2)=5
step 2. add the 2 to the 5
K=7
Answer: k = 7
Step-by-step explanation: Start by distributing the 3 through the parentheses on the left side of the equation.
3(k) is 3k and 3(-2) is -6.
So we have 3k - 6 = 15.
Next, isolate the k term by adding 6 to both
sides of the equation and we get 3k = 21.
Now divide both sides by 3 and k = 7.
If you want, you can check your answer by plugging a 7
back into the original equation to see if it works.

The amount of money that Li spends on video games depends on how
many games he purchases. If Li has at most $90 to spend on games for his
Xbox 360 and the games cost $22.50 each, what is the domain of this
function?
Answer:
x < 4
Step-by-step explanation:
The function is represented by this equation:
22.5x = y
Where x is the number of games he buys and y is the amount of money that he spends. We know that y cannot be greater than 90, because Li only has 90 dollars. So, if y is less than 90, 22.5x must be less than 90 as well.
22.5x < 90
x < 90/22.5
x < 4

Examine the equation. –3x + 18 = 7x What could you do to isolate the variable term to one side of the equation? Add 3x to both sides. Subtract 3x from both sides. Add 18 to both sides. Subtract 18 from both sides.
Answer:
You would add 3x to both sides. Then divide by 10 on both sides.
What to do to isolate the variable term to one side of the equation is to add 3x to both side
Given the equation, -3x + 18 = 7x, we need to isolate the variable term. To do that, we will follow the steps below;
Add 3x to both sides of the equation to have;
-3x + 18 + 3x = 7x + 3x
18 = 7x + 3x
Swap sides
7x + 3x = 18
10x = 18
Divide both sides by 10
10x/10 = 18/10
x = 1.8
From the steps above, what to do to isolate the variable term to one side of the equation is to add 3x to both side

The price of a cup of coffee was $2.35 yesterday. Today, the price fell to $2.10. Find the percentage decrease. Round your answer to the nearest tenth of a percent.
Answer:
10.6% decrease
Step-by-step explanation:
The percentage change in a quantity is computed using ...
percentage change = ((new value)/(old value) -1) × 100%
= (2.10/2.35 -1) × 100%
= (0.8936 -1) × 100%
= -.1064 × 100%
= -10.64%
The percentage decrease was about 10.6%.

Complete the point-slope equation of the line through (-9,6)(−9,6)left parenthesis, minus, 9, comma, 6, right parenthesis and (-7,-8)(−7,−8)?
Answer:
Step-by-step explanation:
hello : here is an solution
The equation of the line in point-slope form is y - 6 = -7(x+9)
The equation of a line in point-slope form is expressed as:
y-y0 = m(x-x0)
m is the slope of the line
(x0, y0) is any point on the line
Given the coordinate points (-9, 6) and (-7, -8)
Get the slope of the line:
slope = -8-6/-7+9
Slope = -14/2
Slope = -7
Using the point (-9, 6), the required slope is expressed as:
y - 6 = -7(x-(-9))
y - 6 = -7(x+9)
Hence the equation of the line in point-slope form is y - 6 = -7(x+9)

Can adjacent angles be complementary?
Give a brief explanation as to why or why not.
Answer:
Yes, adjacent angles can be complementary. Complementary angles are defined as two acute angles with a sum that is equal to 90°. if they add up to 90°. For example, a diagonal of a square will split the right angle into two equal angles; 45°+45°. In a right triangle, the altitude from a right angled vertex will split the right angle into two adjacent angles; 30°+60°, 40°+50°, etc. Those adjacent angles are complementary.
