For adults, a bowling alley charges $3.75 for shoe rental and $5 per game. For children, the cost is $2.50 for shoe rental and $4 per game. What expression represents the total cost for one adult and one child to bowl g games?
Answers
Answer:
1x+1y= 9
x= adults y= children 9= the amount they have to pay to play a game if its 1 adult and 1 child
The expression represents the total cost for adults and children:-
Ca = $3.75 + 5g
Cc = $2.50 + 4g
What is an expression?Expression in maths is defined as the collection of numbers variables and functions by using signs like addition, subtraction, multiplication, and division.
Numbers (constants), variables, operations, functions, brackets, punctuation, and grouping can all be represented by mathematical symbols, which can also be used to indicate the logical syntax's order of operations and other features.
Given that for adults, a bowling alley charges $3.75 for shoe rental and $5 per game. For children, the cost is $2.50 for shoe rental and $4 per game.
For adults the expression will be:-
Ca = $3.75 + 5g
For children, the expression will be:-
Cc = $2.50 + 4g
Hence, the expression are Ca = $3.75 + 5g and Cc = $2.50 + 4g.

Answers
Answer:
$66.35
Step-by-step explanation:
To find this answer with y=mx+b, we should first explain what it is. Y is our output or answer. M is our variable and x is the slope of our variable or how often it occurs. B, is our y intercept, our initial starting amount. Knowing this, we must figure out y. To do this we must multiply his hourly wage by the hours he works which is $12.50x5. This will get us $62.50. Now that we know how much he makes hourly, we add his initial wage of $3.85 to get us $66.35
This means he will make $66.35 if he works a full 5 hour shift.

Find the expected value of the winnings from a game that has the following payout probability distribution. Round to the nearest hundreath.
Answers
Step-by-step explanation:
Here, we want to calculate the expected value
What we have to do here is to multiply the probability by the payout value; after which we add all values
Thus, we have the payout value as;
1(0.12) + 4(0.2) +6(0.38) + 8(0.2) + 10(0.1)
= 0.12 + 0.8 + 2.28 + 1.6 + 1
The expected value of the winnings from a game will be [tex]2.96[/tex] .
What is Probability ?Probability is the ratio of the number of possible outcomes to the total number of outcomes.
we have,
Payout [tex](\$) = 0,\ \ \ 1,\ \ \ 2,\ \ \ 5,\ \ \ 10[/tex]
Probability [tex]=0.12,0.2,0.38,0.2,0.1[/tex]
So,
To find the expected value,
Now,
Multiply payout values with its probability and sum these values,
i.e.
Expected value [tex]= (0*0.12)+(1*0.2)+(2*0.38)+(5*0.2)+(10*0.1)[/tex]
[tex]=0+0.2+0.76+1+1[/tex]
Expected value [tex]=2.96[/tex]
Hence, we can say that the expected value of the winnings from a game will be [tex]2.96[/tex] .

What is the perimeter of the rectangle?
Answers
Answer:
10 feet
Step-by-step explanation:
Perimeter of rectangle = 2l+2b
Area of the rectangle = l x b
Area of the rectangle = 4 square feet
possible factors of 4 = 2x2/4x1
So sides of the rectangle are 4 & 1 as 2&2 would make it a square
So perimeter= 2x4+2x1
= 8+2
= 10 feet

In a quadratic function, recall that the discriminant D = b2 - 4ac. For which function is it true that a < 0 and D = 0?
Answers
Answer:
If D = 0, then the quadratic equation has 1 solution x = − b/2a
Step-by-step explanation:
If we have a quadratic equation x² +3x-4= 0
Then the corresponding values of a= 1, b=3, c= -4
Finding the discriminant gives
D= b2 - 4ac.
D= 3²- 4(1) (-4)
D= 9 + 16
D= 25
Here a> 0
But if a< 0 e.g a= -1
D= b2 - 4ac.
D= 3²- 4(-1) (-4)
D= 9 - 16
D= -7
Here a < 0 so we get the answer -7 < 0
D= b2 - 4ac.
D= 4²- 4(-1) (-4)
D= 16 - 16
D= 0
Here a< 0 and b= - c so that D= 0
When D < 0 roots do not exist.
If D = 0, then the quadratic equation has 1 solution x = − b/2a
This can be found out by using the quadratic formula
x= -b±√b²- 4ac/ 2a
But D= 0
x= -b±0/ 2a
x= -b/2a
