Answer:
.25
Step-by-step explanation:
2 eggs are pink
4 eggs are purple
2 eggs are orange
-----------------------
8 total eggs
P( orange) = orange eggs/ total eggs
= 2/8
= 1/4
= .25
1. Multiply the hourly rate by the number of hours worked ( 22.5h) add that to the flat fee ( 22.5h +35) and that needs to be equal to or greater than what he expects to make:
A. 22.5h + 35 ≥ 215 , with a solution of h ≥ 8
2. Same method as number 1:
C. $3 + 1.80m ≤ $25
3. Each fraction would need 1 negative sign and have the same numerator and denominator, so the answer would be B.6/-7
Answer:
plug the a back in
3(6)=18 if the answer is 18 then your right
18=18
Answer:
$42.07
Step-by-step explanation:
If a pair of $55 shoes are discounted by 15%, then $55 (0.15) = 8.25. The pair of shoes were discounted by $8.25.
$55 - $8.25 = $46.75
If a $46.75 pair of shoes is further discounted by 10%, then $46.75 (0.10) = $4.675, or $4.68 rounded.
$46.75 - $4.68 = $42.07
Domain asks for any restrictions on the x-value and the range asks for any restrictions on the y-value.
Let's tackle this one at a time.
Domain: We're dealing with a quadratic function or a parabola, so usually there wouldn't be any restrictions on the x-value. When you graph out this parabola, you can see that the x-values will continue to grow to infinite and negative infinite.
Hence, there are no restrictions for the domain, and it would be all real values.
Range: Now, based on the graph, there is definitely a point at where the graph doesn't exist anymore. For a concave up or down, the range would always be greater or less than the x-value of the vertex. In this case, we have a concave up parabola, and as such, we would have a y-value that exists for when y ≥ -3
