Answer:

1/3

Step-by-step explanation:

you add the 2x onto the 4x to get 6x on one side on the other side you add on the nine so now you have 18=6x then you divide by 18 to get 6/18 or simplified 1/3 also 33.3 as a decimal

Suppose the foot of a 12-foot ladder was placed 4 feet from a building how high up on the building would the top of the ladder r

NikAS [45]

Use the pythagorean theorem.

The foot of the ladder is 4 feet away from the building (leg 1)

The height of the building is leg 2

The ladder, which would be at an angle, is 12 feet. So our hypotenuse would be 12. The equation for this would be a²+4²=12²

We can then begin to solve

a² + 16 = 144

a² = 128

a=11.31

So, our answer is: The top of the ladder reaches the building at 11.31 feet up

How many kilometers is it from the main gate to Manatee Springs? (Hint: To convert from

Luda [366]

Answer:

Distance between Main gate M and manatee Spring S,

MS = 6.035 km ≅ 6 km (rounded off)

Step-by-step explanation:

Let the point at Train depot be T. Point at Main gate be M. Point at Bird sanctuary be B. Point at Elephant house be E. Point at manatee Springs be S.

Now, we have two triangles TMB and TSE.

From figure given that, ∠MTB = ∠STE

∠TMB = ∠TSE

∠TBM = ∠TES.

⇒ From AAA similarity, Triangles TMB and TSE are similar.

⇒ $\frac{TM}{TS} = \frac{TB}{TE}$

⇒ $\frac{x}{4200} = \frac{2000}{3500}$

⇒ x = 2400 yds

⇒ Distance between Main gate M and manatee Spring S,

MS = MT + TS = x + 4200 = 2400 + 4200 = 6600 yds

⇒ MS = 6600 yds = 6600 × 0.0009144 km = 6.035 km ≅ 6 km
