So it is negative 6 minus (-2). Change the subtraction symbol to a addition one and move the subtraction symbol with the negative two in parentheses. Since two negative equal a positive, your equation will be "-6+2". You can d the math from there

A factory produces 6 motorcycles in 9 hours. Find how many hours it takes to produce 16 motorcycles at this rate
Allushta [10]

Answer: 24 Hours

Step-by-step explanation:

6 Motorcycles = 9 Hours

divide the hours by the motorcycles and you get 1.5, so that is how long it takes for one motorcycle.

Multiply 16 by 1.5 and you get 16 Motorcycles in 24 Hours

125°<br> 1 5<br> 5<br> The measure of 1=<br> Helppppppppppp
Anton [14]

Answer: the measure of angle 1 is 55 degrees

Step-by-step explanation:

so you see the outside of 5 is 125 degrees on the right side? So that 125 is equal to the 5 on the other side. So to find measure 1 you need to figure out the measure of the rest of the outside which is the outer angle of measure 1.

So you do

125+125=250

and then,

360-250=110

and since measure of angle 1 starts at the edge of the angle and not the center, you do 110/2 which is 55.

IF THE ANGLE OF MEASURE 1 WAS FROM THE CENTER POINT TO THE END <u>DO NOT </u>DIVIDE BY TWO.

Any answers? im bit stuck on this
Aleks04 [339]

Step-by-step explanation:

The vertical angles are congruent. The right angles are congruent. There are 2 angles of a triangle congruent to 2 angles of anther triangle. By AA Similarity the triangles are similar.

Statement A. (vertical angles are congruent)

Statement D. (right angles are congruent)

Triangle AEC is similar to triangle BDC.

Statement E is true but does not help.

Correct statement of proportional side lengths:

BD/AE = CD/CE

x/150 = 200/50

x/150 = 4

x = 600

P.S. I think there is a mistake in the problem. I don't think that statement E is correct. It is a true statement, but it is useless. Statement F is false.

The number of bacteria present in a culture after t minutes is given as where k is a constant. if there are 8520 bacteria presen
andrew-mc [135]
Given that the situation has been modeled by the formula:
B=1000e^(kt)
given that B=8520 after t=15 min
then the value of k will be solved as follows:
plugging in the values in the formula and solving for k
8520=1000e^(15k)
8.52=e^(15k)
solving for k
15k=ln(8.52)
hence
k=ln(8.52)/15
k=0.1428
k=0.143
