Answer:

40

Step-by-step explanation:

6% of number = 6/100 × x = 6x/100 = 3x/50

Sum of the number and 6% of itself = 42.4

x + (3x/50) = 42.4

(50x+3x)/50 = 42.4

53x = 42.4 × 50

53x = 2120

x = 2120/53

x = 40

Answer:

The answer is  x = 40

Step-by-step explanation:

6% of a number is 6/100 * x

Of means multiply.

so 6% of x =    6/100 * x =    6 * x / 100 =    0.06x

Now just put these two together.

x + 0.06x = 42.4    Combine the left

1.06x = 42.4           Divide by 1.06

x = 42.4 / 1.06

x = 40

Tyler was shoving an equation and his last line of work read -12=12. What does this mean
wolverine [178]

Answer:

Step-by-step explanation:

-12 = 12 ....this is incorrect...meaning no solutions

**

if it ended in :

x = a number, or y = a number...means there is 1 solution

if it ended in :

-12 = 12....incorrect answer, means there is no solutions

if it ended in :

2 = 2 or -4 = -4....correct answer, but not variable...means infinite solutions

Mkey [24]

Answer:

  • See below

Step-by-step explanation:

<u>Given function:</u>

  • p(t)=3.1(1.016)^t

<u>The base of the growth rate is:</u>

  • 1.016 = 1 + 0.016

It represent a 1.6% of growth per year.

A.

  • Increasing

B.

<u>p(55) = 7.42 means:</u>

  • 55 years after 1963, in the year 2018, the population of Earth is 7.42 billions

If you had a 15 foot ladder, how far away from the base of a wall would you have to put it to reach a window 12 feet up?
Kruka [31]

Answer:

9.000000001

Step-by-step explanation:

If the hypotenuse is  15, the ladder, facing the right angle, and the opposite is 12 we need to use SOH to find the angle.

sin of angle is opposite / hypotenuse

sin of angle is 12 / 15

12/15 = 0.8

sin^-1 of 0.8 = 53.13010235

Angle is that

Then we do this again but a different equation

cos of angle is adjacent (x which we are looking for) / hypotenuse

cos of 53.13... is x / 15

(15 x cos of 53.13... )is x

So 15 x cos of 53.13... is 9.000000001 feet away.
