The maximum whole number of hours is 4 hours.
Answer: B
Step-by-step explanation:
<u>if 4w-1 ≥0</u> or w > 1/4 then
|4w-1|=4w-1
4w-1=5w+37 ==> w=-38 (exclude since not >1/4)
<u>else</u>
4w-1 < 0 or 4w <1 or w < 1/4
|4w-1|=-(4w-1)
-(4w-1)=5w+37
-4w+1=5w+37
9w=-36
w=-36/9
w=-4 ( which is < 1/4)
Sol={-4}
Answer B
Answer:
-7
Step-by-step explanation:
since it is the 10th term, i think you need to plug in 10 as n
which is,
3 - (10) = -7
hope it's correct and hope it helps!!
Answer:
y = 2.25x
Step-By-Step Explanation:
If I divide y by x, in any of the tables, it is always 2.25.
y ÷ x = 2.25
Then, I can multiply x on both sides to make the equation showing the proportional relationship.
y ÷ x × x = 2.25 × x
y = 2.25x

Answer:
25
+60
Step-by-step explanation: The first thing you need to do is realize that, this figure is a isosceles trapezoid due to the markings on each side.
So now we know both sides are 10.
We also know the the top two angles are congruent to each other and so are the bottom two angles due to the trapezoid being isosceles.
So the top two angles are 120 degrees and bottom two angles are 60 degrees.
It seems like we can't find the sides, let's try drawing two lines from each top angle all the way down to form two right triangles.
Wow, these two triangles are special right triangles in the form of
30 - 60 - 90 degrees.
shorter side = n
longer side = n![\sqrt{3}](https://tex.z-dn.net/?f=%5Csqrt%7B3%7D)
hypotenuse = 2n
So, 2n = 10
n = 5 for the short side
The bottom base is 4
+ 5 + 5 = 10 + 4![\sqrt{3}](https://tex.z-dn.net/?f=%5Csqrt%7B3%7D)
The longer side is 5
.
The area of trapezoid = (base1 + base2)/2 * height
= (4
+ 10 + 4
)/2 * 5
= (10 + 8
)/2 * 5
= (5+4
)*5
= 25
+60
So, 25
+ 60 is our answer.
