By what number would you multiply to solve 4/5 t = 36

mihalych1998 [28]

Answer:

Step-by-step explanation:

4/5 t = 36

Divide both sides by 4/5

4/5 / 4/5 t = 36/4/5

4/5 cancels 4/5

Also flip the divisor 4/5

t = 36x5 / 4

= 180/4

= 45

A construction company is planning to bid on a building contract. The bid costs the company $1400. The probability that the bid

liubo4ka [24]

Answer:

$3,000

Step-by-step explanation:

There two possible outcomes:

There is a 3/4 chance that the bid is rejected for a value of -$1,400

There is a 1/4 chance that the bid is accepted for a value of $17,600 - $1,400.

The expected value of the situation is:

$E = \frac{3}{4}*(-1,400)+\frac{1}{4}*(17,600-1,400)\\E=\$3,000$

The expected value is $3,000.

Solve for x. 2x² +21x-61 = (x+7)² Please

Ymorist [56]

Answer:

$x = \frac{-7 +\sqrt{489} }{2}$

$x = \frac{-7 - \sqrt{489} }{2}$

Step-by-step explanation:

2x² +21x-61 = (x+7)²

expand

2x² + 21x - 61 = x² + 14x +49

move everything to one side

x² + 7x - 12 = 0

use quadratic formula

$x = \frac{-b +- \sqrt{b^{2}-4ac } }{2a}$

plug in the values

$x = \frac{-7 +- \sqrt{7^{2}-4(1)(-110) } }{2(1)}$

solve

$x = \frac{-7 +- \sqrt{49-4(1)(-110) } }{2}$

$x = \frac{-7 +- \sqrt{49 + 440 } }{2}$

$x = \frac{-7 +- \sqrt{489} }{2}$
