What is -3/5 x 5/16 x 7/12 ➗-3/16 x -5/7?

Answers

Answer 1

Answer:

Answer:

-49/60.

Step-by-step explanation:

To simplify the expression -3/5 x 5/16 x 7/12 ÷ -3/16 x -5/7, we can follow these steps:

1. Multiply the numerators and denominators of all the fractions together:

(-3 x 5 x 7) / (5 x 16 x 12) ÷ (-3 x -5) / (16 x 7)

2. Simplify the multiplication of the numerators and denominators separately:

-105 / 960 ÷ 15 / 112

3. When dividing fractions, we can multiply by the reciprocal of the second fraction:

-105 / 960 x 112 / 15

4. Multiply the numerators and denominators together:

(-105 x 112) / (960 x 15)

5. Simplify the multiplication:

-11760 / 14400

6. Reduce the fraction by dividing both the numerator and denominator by their greatest common divisor, which is 240:

-49 / 60

What is the answer to this 17x-9(x+4)=3x-26

Answers

17x - 9(x + 4) = 3x - 26

First, expand to remove parentheses.
$17x - 9x - 36 = 3x - 26$
Second, subtract 17x - 9x to get 8x.
$8x - 36 = 3x - 26$
Third, add 36 to both sides.
$8x = 3x - 26 + 36$
Fourth, simplify.
$8x = 3x + 10$
Fifth, subtract 3x from both sides.
$8x - 3x = 10$
Sixth, subtract 8x - 3x.
$5x = 10$
Seventh, divide both sides by 5.
$x = (10)/(5)$
Eighth, since 2 goes into 5 to get 10, simplify the fraction to 2.
$x = 2$

Answer: x = 2

AC and BD are perpendicular bisectors of each other. Find the perimeter of ADE. m<D = 12, AB = 13, EC = 5.

Answers

The perimeter of the triangle ΔADE will be 30 units.

What is the perimeter of a triangle?

Let the triangle be ABC.

Then the perimeter of the triangle will be

Perimeter = AB + BC + CA

AC and BD are perpendicular bisectors of each other.

The diagram is shown below.

P = AD + DE + EA

P = 13 + 12 + 5

P = 30 units

#SPJ2

THE CORRECT ANSWER IS 30.

AC and BD are perpendicular bisectors of each other.

=> ABCD is rhombus.

AD = 13

AE = √(13^2 - 12^2) = 5

the perimeter of triangle ADE = 13+12+5 = 30

Step-by-step explanation:

A machine needs 2 of its gears replaced. You find 2 gears, one manufactured 5 years ago and the other manufactured 10 years ago. The specifications sheet says that the chance of failure is 5% after 5 years and increases to 8% after 10 years. If the gears on the machine are in no way linked to each other, what are the chances that both will fail? Answer in % form.If someone could show me the steps I would really appreciate it! Thanks!!!

Answers

Probability that gear 1 will fail = 5/100 (upto 10 years)
and 8/100 (after 10 years)

Probability that both will fail = 5/100 * 8/100
= 40/10000
= 0.4 %

Answer:

0.4%.

Step-by-step explanation:

If the gears on the machine are not linked to each other, the probability that both replacement gears will fail is 0.4%.

This is not the equation of a line, because it doesn't say " y = something".
It doesn't have a graph, or a slope or an intercept.

It's just an equation that you can solve to find out what number 'x' is.
