Diego is selling raffle tickets for $1.75 per ticket.
Complete the table to show how much money he would earn if he sold each number of tickets.
Answer:
1.75(x)
Step-by-step explanation:
you can make an algebraic expression to make this simpler. if x = the number of tickets. then, you want to create the expression. it will be .... 1.75(x).
you plug whatever number you need for the table in as x. for example, if you want to see how much money diego would make for 6 tickets you write 1.75*6

Answer:
I'm not 100% sure, but I think the answer is 10 units squared.
Step-by-step explanation:
Find the area of each triangle, by multiplying each side, and dividing the answer in half. Add both of the triangles together, ending up as 6. Now we just find the area of the square. 2x2=4, add that to both of the triangles, and we're done. (2x2) ÷ 2 = 2 | (2x4) ÷ 2 = 4 | 2x2 = 4 | 4+4+2=10
Answer:
area=10 units^2
Step-by-step explanation:
[tex]a=\frac{(2+2+4)+(2)}{2} *2\\ =\frac{8+2}{2} *2\\ =\frac{10}{2} *2\\ =5*2\\ =10[/tex]
a=10 units^2
Find 2 and 3 please explain how u got ur answer
solve each system by substitution
1/2x+1/3y=6
x-y==2
Step-by-step explanation:
First, let's rewrite the equations.
1/2x + 1/3y =6
x - y = 2
The easiest system to use for substitution is the second one. Let's solve for X.
x - y = 2
add y to both sides!
x = 2 + y
Now that we know x = 2 + y we can use it to substitute in the first equation.
1/2(2 + y) +1/3y = 6
1 + 1/2y +1/3y = 6
5/6y = 5
y = 36/5

The americans with disabilities act sets a maximium angle for a wheelchair ramp entering a business at 4.76 degrees. Determine the horizontal distance needed to occomidate a ramp that goes up to a door.
Answer:
d = 48.03 feet
Step-by-step explanation:
Given that,
The maximum angle for a wheelchair ramp entering a business at 4.76 degrees.
We need to find the horizontal distance needed to accomidate a ramp that goes up to a door 4 feet of the ground.
We can solve it using trigonometry.
[tex]\tan\theta=\dfrac{h}{d}[/tex]
Where
h is height
d is the angle of elevation
[tex]d=\dfrac{h}{\tan\theta}\\\\d=\dfrac{4}{\tan(4.76)}\\\\d=48.03\ ft[/tex]
So, the horizontal distance is equal to 48.03 feet.
A store sells watches for $69.99 each and watch batteries for $9.50 each. Justin is buying 2 watches and x number of watch batteries. Which equation can be used to find y, the total price Justin must pay in dollars?
A y = 139.98x + 9.50x
B y = 69.99x + 9.50
C y = 9.50x + 69.99
D y = 9.50x + 139.98
Answer:
D. y= 9.50x + 139.98
Step-by-step explanation:
69.99 x 2 = 139,98

find the excerpted value
Answer:
The expected value is $4.35
Step-by-step explanation:
Here, we want to find the expected value
To
do that, we simply will multiply each of the payouts by the individual probabilities, then add the results
Mathematically, we have this as;
0.35(1) + 0.2(2) + 0.1(5) + 8(0.2) + 10(0.15)
= 0.35 + 0.4 + 0.15 + 1.6 + 1.5 = $4.35

You have two decks of cards and you select a card from each deck. What is the probability to selecting a jack both times?
Answer:
The probability is 1/13 (1 to 13).
Step-by-step explanation:
In a card deck, there are 52 cards with 4 Jacks. If you simplified this probability, the answer would be 1 to 13.
4/52 = 1/13
In two card decks, there are 104 cards with 8 jacks. If you simplified this probability, the answer would also be 1 to 13.
8/104 = 1/13
