Four friends are playing the board game Hidden Treasure. The game begins with 40 coins
divided evenly among the four players. Each player keeps 2 of their coins on the table and
keeps the rest of the coins inside their bag.
Let b equal the number of coins in each bag.
Which equation represents the total number
of coins the four players have?
4(b+2)=40
4b=40
b+2=49
4b+2=40
Answer:
I hope this helps 40 divided by 4 is 10 10 per person 10-2=8 8 coins in each players bag and the total amount of coins in bags is 8 times 4 which is 32

Which of the following inequalities matches the graph?
Answer:
6x - y < -3
Step-by-step explanation:
When graphing inequalities:
< or > = dashed line
≤ or ≥ = solid line
< or ≤ = shade below the line
> or ≥ = shade above the line
Create an equation for the line
Choose 2 points on the line:
let (x₁, y₁) = (-1, -3)let (x₂, y₂) = (0, 3)Calculate the slope:
[tex]\sf \textsf{slope}\:(m)=\dfrac{y_2-y_1}{x_2-x_1}=\dfrac{3-(-3)}{0-(-1)}=6[/tex]
Determine the equation for the line using the point-slope formula:
[tex]\implies\sf y-y_1=m(x-x_1)[/tex]
[tex]\implies \sf y-(-3)=6(x-(-1))[/tex]
[tex]\implies \sf y+3=6(x+1)[/tex]
[tex]\implies \sf y=6x+3[/tex]
As the shading is above the line:
⇒ y > 6x + 3
Compare with answer options
Rearrange each answer option to make y the subject:
Option (a)
-6x + y < 3
⇒ y < 6x + 3
Option (b)
6x + y < 3
⇒ y < -6x + 3
Option (c)
6x - y < -3
⇒ -y < -6x - 3
⇒ y > 6x + 3
Therefore, as option C matches the calculated inequality, the answer is
6x - y < -3
Answer:
6x - y < 3
Step-by-step explanation:
Finding the equation of the inequality :
Slope :
⇒ m = 3 - (-3) / 0 - (-1)
⇒ m = 6/1
⇒ m = 6
Y-intercept :
⇒ (0, 3)
Equation :
⇒ y = 6x + 3
Here :
⇒ Above the origin, so it is greater than ( > )
⇒ y > 6x + 3
⇒ 6x - y < 3
Last year, the number of skateboards produced by a skateboard company is normally distributed. The standard deviation of skateboards produced was 20 skateboards. They found they produced up to 280 skateboards on 93.32% of the days last year. Use this information to find the average number of skateboards produced per day last year.
The average number of skateboards produced per day last year is 310.
What is a normal distribution?It's the probability curve of a continuous distribution that's most likely symmetric around the mean. On the Z curve, at Z=0, the chance is 50-50. A bell-shaped curve is another name for it.
We have:
The standard deviation of skateboards produced was 20 skateboards. They found they produced up to 280 skateboards on 93.32% of the days last year.
Z- score at 93.32% is -1.5
We know:
[tex]\rm Z = \dfrac{(x - \mu)}{\sigma}[/tex]
[tex]\rm -1.5 = \dfrac{(280 - \mu)}{20}[/tex]
μ = 280 + 30
μ = 310
Thus, the average number of skateboards produced per day last year is 310.

The price of a box of colored pencils increased from $8.00 to $8.48. What was the percent increase in the price?
Step-by-step explanation:
100% = $8.00
1% = 100%/100 = 8/100 = $0.08
the price went up by $8.48 - $8.00 = $0.48.
how many % is this ?
as many % as 1% fits into this difference :
0.48 / 0.08 = 6%
the price increase was 6%.

buffy's beverages has increasing profits each week during the hot summer months. Buffy finds that each week his profits increase by 20% over what they were the previous week. In his first week of business his profits were $200
The exponential function that gives the profit after x weeks is given by:
[tex]P(x) = 200(1.2)^x[/tex].
What is an exponential function?An increasing exponential function is modeled by:
[tex]A(t) = A(0)(1 + r)^t[/tex]
In which:
A(0) is the initial value.r is the growth rate, as a decimal.In this problem:
Buffy finds that each week his profits increase by 20% over what they were the previous week, hence r = 0.2.In his first week of business his profits were $200, hence A(0) = 200.Thus, the equation is given by:
[tex]A(x) = 200(1 + 0.2)^x[/tex]

Find the area of the kite
Answer:
180
Step-by-step explanation:
(10×11)+(10×7)=110+70
The area of the kite is expressed as 1/2 × (Product of its diagonals)
In this case, we have;
Diagonal₁ - 10 + 10 feet = 20 feetDiagonal₂ - 7 + 11 feet = 18 feetTherefore, when we substitute the diagonals in the formula, we get;
⇒ 1/2 × (Product of its diagonals)⇒ 1/2 × (20 × 18)When simplified, we get;
⇒ 1/2 × (20 × 18)⇒ 1/2 × (360)⇒ 360/2 = 180 ft²Therefore, the area of the kite is 180 ft².
