Answer:15 hours
Step-by-step explanation:
15+5=20
20+20=40
13+17=30
Add
90 hours
90÷6= 15
15 hours
That’s easy. 6000 x 6% = 360 x 20 = 7200
6000 + 7200 = 13200
Answer: All real numbers greater than or less than 9.
Step-by-step explanation: The range is possible y-values. In a parabola the range starts at a particular place then it either goes up or goes down. Since the leading factor has a negative in front of it, the parabola will open downward meaning most likely all y-values will be lest than the include max point. Now let find the max point using the formula -b/2a then substituting that into the parabola. -2/2(-1)= 1, then plug it in. y=-(1^2)+2(1)+8 which equal -1+2+8 which equal 9 so the max point is 9. Since the graph open downward all the points that are possible will either be at 9 or below it so the range is All real numbers greater than or less than 9. or (-∞,∞)∪(∞,9]
Answer:
The hypotenuse is 10 units
Step-by-step explanation:
Considering the right angle triangle, we apply pythagora's theorem to determine the hypotenuse;
Where a and b are the lengths of the two shorter sides.
In this case we have;
I'm assuming the blueprint shows 1 inch is equal to 10 ft. This means that 1 inch on the blueprint corresponds to 10 feet in real life.
We have the ratio
1 inch: 10 feet
If we multiply both sides by 0.5 then,
0.5*(1 inch) : 0.5*(10 ft)
0.5 inch : 5 feet
So 0.5 inches (aka half an inch) on the blueprint corresponds to 5 feet in real life.
Answer: A) 5 feet
