Answer: D. 9.2 m
The angle of elevation of a ladder leaning against a wall is 60º and the foot of the ladder is 4.6 m away from the wall. The length of the ladder is:____________A. 2.3 mB. 4.6 mC. 7.8 mD. 9.2 m
Step-by-step explanation:
Given;
Angle of elevation A= 60°
Distance from the foot of the ladder to the wall x= 4.6m
Length of the ladder = L
CosA = adjacent/hypothenus = x/L
L = x/cosA
L = 4.6/cos60°
L = 9.2m
The length of the ladder is 9.2m
Answer:
Step-by-step explanation:
The admission to the fair is $5 and the cost per ride is 50 cents.
Let the number of rides that he can go on be x
If one ride costs 50 cents, x rides will cost 50×x = 50x cents. Converting 50 cents to dollar, it becomes 50/100 = $0.5.
So x rides will cost $0.5x
If his parents gave him $20, he will pay $5 to be admitted into the fair. He would be left with 20- 5 = $15
The equation to find how many rides he can go on will be
0.5x = 15
Since one ride costs $0.5
x rides cost $15
x = 15/0.5 = 30
He can go on 30 rides
You should buy 576 grams of cereal. I believe this is right because 32g x 18=576. But you might want me to work it different or something.
Answer:
Slope: 3
Y-Intercept: -10
Step-by-step explanation:
This equation is in slope-intercept form, it is written as y = mx + b where m is the slope and b is the y-intercept. This means 3 is the slope and -10 is the y-intercept.
