Answer:
12
Step-by-step explanation:
Since 15 is 3 times the ratio you multiply 4 by 3
Answer:
208cats
Step-by-step explanation:
⅝=tongue
³/16=straw=39cats
⅝+³/16=13/16
meaning total number of cats is 16/16
If ³/16=39cats
16/16=?
39×16/3
=208cats
Answer: 1st,2nd, and 4th one are correct.
Step-by-step explanation:
Answer:
2
Step-by-step explanation:
w + 1/2 ➡ (2w + 1)/2
w/4 + 2➡ (w + 8)/4
(2w + 1)/2 = (w + 8)/4
8w + 4 = 2w + 16 ➡ 6w = 12
w = 2
Answer: 9.19 ft
Step-by-step explanation:
Hi, since the situation forms a right triangle (see attachment) we have to apply the next trigonometric function.
Sin α = opposite side / hypotenuse
Where α is the angle of elevation of the ladder to the ground, the hypotenuse is the longest side of the triangle (in this case is the length of the ladder), and the opposite side (x) is distance between the top of the ladder and the ground.
Replacing with the values given:
Sin 45 = x/ 13
Solving for x
sin45 (13) =x
x= 9.19 ft
