Mathematics
1 answer:
lara [203]2 years ago
3 0

Step-by-step explanation:

x = BD

\frac{ab}{ad}  =  \frac{bc}{de} \\  \frac{10}{10 + bd}   =  \frac{12}{21}  \\ 12 \times (10 + bd) = 21 \times 10 \\ 120 + 12bd = 210 \\ 12bd = 210 - 120 \\ 12bd = 90 \\ bd =  \frac{90}{12} \\ bd = 7.5 \\

A 24-foot ladder is placed against a vertical wall of a building, with the bottom of the ladder standing on level ground 6 feet
andrezito [222]

Answer:

23.24 feet

Step-by-step explanation:

Use the pythagorean theorem: a² + b² = c², where a and b are legs of the right triangle and c is the hypotenuse.

In this situation, the ladder is the hypotenuse of the triangle, and the distance from the base of the building is the long leg.

Plug in the ladder length as c and plug in the distance from the base of the building as a:

a² + b² = c²

(6²) + b² = (24)²

36 + b² = 576

b² = 540

b = 23.24

So, the ladder reaches approximately 23.24 feet up the wall

Write a ratio for the follow description : Kaleel made three times as many baskets as many baskets as john during basketball pra
andrew-mc [135]

3:1 because she makes 3 times more baskets than John.

If a bowl of fruit contains 8 lemons and 6 oranges, then the ratio of oranges to lemons is eight to six or 8:6 which then can be reduced by to 4:3.

You reduce it by a common factor they share such as 2, because 2 x 4 = 8 and 2 x 3 = 6.

Hope that is the answer you seek.
