Please help with this question, will be appreciated if there is an explanation

If they manage to sell t tickets, they will earn 15\cdot t dollars. We want this number to be at least 1000, so the inequality would be

15t>1000

In order to solve this for t, you only need to divide both sides by 15:

15t>1000\iff t>\dfrac{1000}{15} = 66.\overbar{6}

So, they need to sell at least 67 tickets to have an income of

15\cdot 67 = 1005 dollars

Scientists are examining two different strains of a particular bacteria. The length of one strain of the bacteria measures 0.000
vesna_86 [32]

Scientists are examining two different strains of a particular bacteria. The length of one strain of the bacteria measures 0.000000368

mm, while the length of the second strain measures 0.000000064 mm. How much larger is the first strain than the second?

We can figure this out using scientific notation.

0.000000368 - 0.000000064

= 3.04e-7

Put 3.04e-7 in standard notation.

0.00000304

Put 0.00000304 back into scientific notation, instead with a multiply sign.

Move the dot back, making the number in between 1-10.

In this case, we would move it back 7 times.

3.04 · 10x^{-7}

So the answer would be A.

-12x=-75-11y<br> -5x=-89-11y
Elenna [48]
12x - 11y = 75 . . . . . . . . (1)
5x - 11y = 89 . . . . . . . . (2)
(1) - (2): 7x = -14
x = -2
From (1): 12(-2) - 11y = 75
-24 - 11y = 75
-11y = 75 + 24 = 99
y = -9
Therefore, x = -2 and y = -9
