Heather had to collect insects for her biology project. She was able to collect 225 total insects. She collected 8 times as many
GREYUIT [131]

200 flying insects she catch for her project .

<u>Step-by-step explanation:</u>

We have , Heather had to collect insects for her biology project. She was able to collect 225 total insects. She collected 8 times as many insects that could fly as insects that couldn't fly. That means insects ratio of non-fly to fly is 1:8 .

There are a total of 225 insects , and for every one non fly insect there are 8 fly insects  , Let x be the number of insects that can't fly so:

x + 8x = 225

⇒ x + 8x = 225

⇒ 9x = 225

⇒ \frac{9}{9}x = \frac{225}{9}

⇒ x = \frac{225}{9}

⇒ x = 25

So , Number of fly insects = 8x = 8(25) = 200 . ∴ 200 flying insects she catch for her project .

PtichkaEL [24]

Answer:

A) 99.5%

B) 42.1%

Step-by-step explanation:

A) Since the probability of 3 sixes is 0.5%, the probability of less than 3 sixes (that is, zero, one, or two sixes) is 100% - 0.5%, or 99.5%

B ) Since the probability of no sixes is 57.9%, the probability of at least 1 six is 100% - 57.9%, or 42.1%

Help i don't get it. I've been trying
ASHA 777 [7]

Answer:

JK = 42 , KL = 78

Step-by-step explanation:

JK + KL = JL , substitute values

4x + 6 + 7x + 15 = 129 , that is

11x + 21 = 120 ( subtract 21 from both sides )

11x = 99 ( divide both sides by 11 )

x = 9

Then

JK = 4x + 6 = 4(9) + 6 = 36 + 6 = 42

KL = 7x + 15 = 7(9) + 15 = 63 + 15 = 78
