Answer: 18 inches
Step-by-step explanation:
We can represent the whole situation by the formula
solve by cross product
50x = 900
x = 18
Answer:
1st picture: (0,4)
The lines intersect at point (0,4).
2nd picture: Graph D
2x ≥ y - 1
2x - 5y ≤ 10
Set these inequalities up in standard form.
y ≤ 2x + 1
-5y ≤ 10 - 2x → y ≥ -2 + 2/5x → y ≥ 2/5x - 2
When you divide by a negative number, you switch the inequality sign.
Now you have:
y ≤ 2x + 1
y ≥ 2/5x - 2
Looking at the graphs, you first want to find the lines that intersect the y-axis at (0, 1) and (0, -2).
In this case, it is all of them.
Next, you would look at the shaded regions.
The first inequality says the values are less than or equal to. So you look for a shaded region below a line. The second inequality says the values are greater than or equal to. So you look for a shaded region above a line.
That would mean Graph B or D.
Then you look at the specific lines. You can see that the lower line is y ≥ 2/5x - 2. You need a shaded region above this line. You can see the above line is y ≤ 2x + 1. You need a shaded region below this line. That is Graph D.
Answer:
-7.53179190751
Step-by-step explanation:
(55-63)+((20 1/4)/(43 1/4))=
-8+0.46820809248= -7.53179190751
SA = 2( width Height + length Width + Length Height)
w= 12cm, h= 10cm and l=15cm
SA = 2( 12cm * 10cm + 15cm * 12cm + 15cm * 10cm)=450 cm^2
hope helps.
176:20
44:5 - Lowest Terms
176 and 20 are both divisible by 4; their common denominator is 4.
