An access ramp to a building is 3.7 m long. The distance from beginning of the ramp to the base of the building is 3.5 m. How ta

hichkok12 [17]

Answer: 1.2 m

Step-by-step explanation:

Given

The length of the ramp to the building is 3.7 m

Distance from the beginning of the ramp to the base of the building is 3.5 m.

Suppose h is the height of the ramp

from the figure, we can write

$\Rightarrow 3.7^2=3.5^2+h^2\\\Rightarrow 13.69-12.25=h^2\\\Rightarrow h^2=1.44\\\Rightarrow h=1.2\ m$

So, the height of the ramp is 1.2 m

(4y − 3)(2y2 + 3y − 5)

IRINA_888 [86]

Answer:

$8y^3 + 6y^2- 29y + 15$

Step-by-step explanation:

$(4y-3)(2y^2+3y-5)\\4y(2y^2 + 3y - 5) - 3(2y^2+3y-5)\\8y^3+12y^2-20y-3(2y^2+3y-5)\\8y^3+12y^2-20y-6y^2-9y+15\\8y^3+6y^2-29y-9y+15\\= 8y^3+6y^2-29y+15$

Suppose you draw a card from a well-shuffled deck of 52 cards. What is the probability of drawing a 5 or a queen?

goldfiish [28.3K]

A 5 or a queen

52 cards per deck
each card repeats 4 times

a 5 or a queen
there are four 5's and four queens
4+4=8

probablity=desiredoutcomes/totalpossible
probablity=8/52
probablity=4/26
probablity=2/13

Carlo sold his house for P8,000,000. The real-estate agent got a 5% commission from the sales.

Daniel [21]

Answer:

The net amount received is 7,120,000

Step-by-step explanation:

The computation of the net amount received is shown below:

= Sale value of the house - real agent commission - expenses

= 8,000,000 - 8,000,000 × 5% - 8,000,000 × 6%

= 8,000,000 - 400,000 - 480,000

= 8,000,000 - 880,000

= 7,120,000

Hence, the net amount received is 7,120,000

The same is relevant
