It must be 21.3 feet.
The sides of the triangle given to us are the side opposite the angle to the ground, 20, and the missing side is the hypotenuse.
opposite/hypotenuse is the ratio for sine:
sin 70 = 20/x
Multiply by x:
x sin 70 = 20
Divide both sides by sin 70:
(x sin 70)/(sin 70) = 20/(sin 70)
x = 21.283 ≈ 21.3
In order to solve the equation shown we'll need either the numeric variable for Q or P
Take the x-axis and y-axis and locate the point on the graph. if it is exactly on the line it is a solution. Alternatively you could take the equation in the form of y=mx+b or ay+bx=c and replace the variables with the actual numbers and see if the equation makes sense
Answer:
Cameron found 23 quarters and 57 dimes.
Step-by-step explanation:
Let the number of quarters Cameron found = Q
And the number of dimes = D
Since, total number of coins were 80,
Q + D = 80 -----(1)
Total amount of the coins was $11.45,
0.1D + 0.25Q = 11.45
10D + 25Q = 1145
2D + 5Q = 229 -----(2)
Equation (1) multiplied by 2 then subtracted by equation (2),
(2D + 5Q) - 2(Q + D) = 229 - 2(80)
(2D - 2D) + (5Q - 2Q) = 229 - 160
3Q = 69
Q = 23
From equation (1),
23 + D = 80
D = 57
Cameron found 23 quarters and 57 dimes.
Answer:
A. The data show a negative linear relationship.
Step-by-step explanation:
According to the attached image as we can see that the temperature is in Y axis and volume of ice cubes is in X axis
So the following statements considered to be true
a. The volume represents the explanatory variable
b. Temperature would be strongly correlated to the ice cubes volume
c. As the correlation coefficient is near to -1
But it does not show the negative linear relationship
Therefore the correct option is a.
