Answer:
x=24
y=144
Step-by-step explanation:
y= 144(corresponding angle)
y =(x+12) ( straight angle)
Multiply (2.6 x 10^-7) by 15 to get
3.9 x 10^-6
Answer:
105,413,504
Step-by-step explanation:
14x14x14= 2,744
14x14x14x14= 38,416
2,744x38,416= 105,413,504
Answer:
30 mph
Step-by-step explanation:
time = distance/speed
If x represents Jane's speed along the summit then her total exploration time is ...
12/x + 40/(x -5) = 2 . . . . . hours
Multiplying by (x)(x -5), we get ...
12(x -5) +40(x) = 2(x)(x -5)
Dividing by 2 and subtracting the left side gives ...
x^2 -31x +30 = 0
(x -30)(x -1) = 0 . . . . . factor
Solutions are x = 30 and x = 1, values of x that make the factors zero. A speed of 1 mph makes no sense in this problem, so ...
Jane's speed along the summit was 30 mph.
From the given figure

Since XY = 5.1 and XZ = 7.7, then

To find x, use the inverse of cos

Use the calculator to find x

The answer is
