five twice the sum of a number and 3 is the same as 3 multiplied by 1 less than twice the number. what is the number? ​
aleksklad [387]

Answer:  -4.5, but only if the phrase "five twice the sum . . ." means 5*2*(the sum of . . .).  "five twice" is confusing, so please check the question.

Step-by-step explanation:

5*2*(X + 3) = 3*(2X - 1)

10X + 15 = 6X -3

4X = -18

X  = -18/4

X = - 4.5

A bike ramp is shown in the figure. What is theta, the bike ramp's angle of elevation? Round your answer to the nearest degree.
AysviL [449]

Answer:

Ф = 14° ⇒ to the nearest degree

Step-by-step explanation:

* Lets revise the trigonometry functions

- Assume that we have a right triangle ABC

∵ m∠B = 90°

∴ AC is the hypotenuse ⇒ opposite to the right angle

∴ AB and BC are the legs of the right angles

- Let angle ACB called Ф

∵ sinФ = opposite/hypotenuse

∴ sinФ = AB/AC

∵ cosФ = adjacent/hypotenuse

∴ cosФ = BC/AC

∵ tanФ = opposite/adjacent

∴ tanФ = AB/BC

* Now lets solve the problem

- We will consider the bike ramp is the ΔABC

∵ AB = 1.5 feet

∵ ∠ACB is Ф

∵ The length of the ramp is the hypotenuse

∴ AC = 6 feet

- W have the length of the opposite to Ф and the hypotenuse

∴ We will chose the sin function

∵ sinФ = AB/AC

∴ sinФ = 1.5/6 ⇒ use the inverse of sin to find Ф

∴ Ф = sin^-1 (1.5/6) = 14.47 ≅ 14° ⇒ to the nearest degree

Answer:

  • shortest: 11 1/8 in
  • longest: 11 3/8 in

Step-by-step explanation:

It should be no surprise that the shortest allowable length is the nominal length less the full allowed tolerance:

  11 1/4 - 1/8 = 11 1/8 . . . inches

__

Likewise, the longest allowable length is the nominal length plus the maximum tolerance:

  11 1/4 + 1/8 = 11 3/8 . . . inches

_____

Of course, you know that 1/4 = 2/8, so adding or subtracting 1/8 gives the fractions shown above.
