Answer:
Step-by-step explanation:
3x +4y= 8, where y =8x-20
3x + 4(8x - 20) =8
3x + 32x - 80 =8
3x +32x =8 +80
35x =88
x=88/35
x= 2.514

Answer:
The snow cone in a cup will hold more.
Step-by-step explanation:
<h3>
Traditional snow cone:</h3>
Firstly, to find the area of the cone you need to know the formula:

So simply plug the values in:

= 217.81 = 218cm³
<h3>Snow cone in a cup:</h3>
To find the area of a cylinder, you need to remember the formula:
The radius is half the diameter so:
Radius = 8 ÷ 2 = 4

So simply plug these values in:

= 251.33 = 251cm³
So this means that because the snow cone in a cup is 251cm³ whereas the traditional snow cone is only 218cm³, the snow cone in a cup will hold more.

Answer:
False
Step-by-step explanation:
Compound probability is the likeliness of two or more events occurring together.
Probability can never be greater than 1 whatever form it takes. Its values range between zero and one. When a probability is multiplied with any particular number such as n ( number of trials) we get expected value or whatever the formula says but probability itself is never greater than 1.
If we get the answer of any question where the found probability is greater than 1 the answer is wrong because probability is not greater than 1.
The sum of all probabilities may be nearly equal to 1 like 0.99999 etc.
Multiply 8 hours by $7.59.
8 * 7.59 = 60.72
Jonah makes $60.72 every day (excluding taxes).
Now multiply this by 10% (0.10).
60.72 * .10 = 6.072
Subtract 6.072 from 60.72.
60.72 - 6.072 = 54.648
Jonah makes $54.65 every day.
