What is the value of triangle in the equation shown? 8 x 4 = (triangle x 7) - (triangle x 3)
GarryVolchara [31]

9514 1404 393

Answer:

  triangle = 8

Step-by-step explanation:

The right side can be factored so that you have ...

  8 x 4 = (triangle x 7) - (triangle x 3)

  8 x 4 = triangle x (7 - 3) . . . . use the distributive property

  8 x 4 = triangle x 4 . . . . . . simplify

  8 = triangle . . . . . . . . . . divide both sides by 4

the main rotor of a helicopter rotates 430 times per minute. find the number of degrees through which a point on the main rotor
n200080 [17]

Answer:

2580 degrees rotated per second

Step-by-step explanation:

since  you have to find the degrees it rotates per second.

you need to divide 430 by 60 to find rotations per second

1)          430/60

             =  7.16666667 rotations per second

-then you have to multiply it by 360 degrees ,because their is 360 degrees in a circle

2)        7.16666667 (360)

            =  2580 degrees rotated per second

Element X is a radioactive isotope such that every 9 years, its mass decreases by half. Given that the initial mass of a sample
4vir4ik [10]

Answer:

2.9 years

Step-by-step explanation:

Given that :

Half-life t1/2 = 9 years

Initial mass = I = 70 grams

A = final mass = 56 grams

t = time taken to reach final amount

Using the exponential half life relation :

A = I(0.5)^t/t1/2

56 = 70(0.5)^t/9

56/70 = 0.5^t/9

0.8 = 0.5^t/9

Log 0.8 = log 0.5^t/9

−0.096910 = −0.301029 * t/9

t/9 = 0.096910 / 0.301029

t/9 = 0.3219291

t = 0.3219291 * 9

t = 2.8973619

t = 2.9 years
