Use parentheses to show two ways of grouping the numbers in 12 • 8 • 25. Tell which expression you think would be easier to simplify, and why. Then simplify the expression.

Answers

Step-by-step explanation:

First no. is 12

Second no. is 8

Third no. of 25

Way 1 of grouping the numbers,

(12×8)×25

We can use associative law of multiplication as follows :

(a×b)×c = a×(b×c)

(12×8)×25 = (96) × 25

= 2400

Way 2,

12×(8×25) = 12 × 200

= 2400

Way 2 is easier to simplify because when we multiply 8 and 25, we get 200. It is very easy to multiply any number with a number that have zeroes. As a result we easily get the answer i.e. 2400.

A biologist recorded a count of 348 bacteria present in a culture after 5 minutes and 1088 bacteria present after 20 minutes. To the nearest whole number, what was the initial population ?

Answers

Answer:

The initial bacteria population is 238

Step-by-step explanation:

Let us have the increase as an exponential equation

P(t) = I(1 + r)^t

where P(t) is the count at a particular time

r is the percentage increase

I is the initial population

t is the time

So for 5 minutes, we have

348 = I(1 + r)^5

For 20 minutes

1088 = I(1 + r)^20

Divide the second equation by the first

1088/348 = I(1 + r)^20/I(1 + r)^5

3.13 = (1 + r)^15

Take the ln of both sides

ln 3.13 = 15 ln (1 + r)

ln 3.13/15 = ln (1 + r)

0.0761 = ln (1 + r)

1 + r = e^0.0761

1 + r = 1.079

r = 1.079-1

r = 0.079 which is 7.9%

So per minute. we have an increase of 7.9%

So let’s get I by substituting

From;

348 = I(1 + 0.079)^5

348/1.079^5 = I

I = 237.9 which is 238 to the nearest whole number

Rachel earns $67.50 for working 9 hours at the dairy farm. How much does Rachel make per hour? How much would Rachel make if she works 5 hours a day for 6 days?

Answers

Answer:

$225

Step-by-step explanation:

Frist, we need to figure out how much Rachel makes per hour. For 9 hours of work, she makes $67.50

67.5 / 9 = 7.5

Rachel makes $7.50 per hour

Now we can add up all the hours she worked.

5 hours a day for 6 days

5 x 6 = 30

She worked 30 hours at a rate of $7.50 per hour

7.5 x 30 = 225

She earned $225

To find what she makes per hour, divide the amount she made by the time she spent. 67.50/9= 7.5 she makes 7.50 per hour. Then if she were to work for 5 hours a day, 7.5(5)=37.5. She makes 37.50 per day and multiply that by 6. She would make 225

Select all that apply.

11. Observe the following and identify the type of angles in them.

Answers

Answer:

breadth=16cm and length=32cm

Let breadth be X

According to question,

lengtg=2X

Now,

Perimeter=2(l+b)

or,96=2(2X+X)

or,96=2(3X)

or,96=6X

or,96/6=X

or,X=16cm.

length =32 cm and breadth =16 cm

Answer:

length = 32 cm, breadth = 16 cm

Step-by-step explanation:

let breadth be b then length is 2b, then

2b + 2(2b) = 96

2b + 4b = 96

6b = 96 ( divide both sides by 6 )

b = 16

Thus

breadth = 16 cm and length = 2 × 16 = 32 cm

Please help me circles.....

Answers

Answer:

Step-by-step explanation:

The equation is

x×2=285-x

3x=285

x=95

Answer:

x = 75°

Step-by-step explanation:

There are many Circle Geometry Rules. We will be using the following:

The angle at the centre of the circle is twice the angle at the circumference.

x = the angle opposite 285 - x.

This means that 360 - (285 - x) = 2x

360 - 285 + x = 2x

75 + x = 2x

We can simplify this by taking away x from both sides.

75 = x

We can check this by substituting x into the orginal equation.

360 - (285 - x) = 2x

360 - (285 - 75) = 2 * 75

360 - 210 = 2 * 75

150 = 2*75

150 = 150

Sodium-24 has a half-life of 15 hours. When will 4 mg of Sodium-24 remain if the original sample contains 64 mg?

Answers

Answer:

60 hours

Step-by-step explanation:

We are given;

Initial amount: A_o = 64 mg

Half life; T_½ = 15 hours

Amount left: A = 4 mg

To get the time that 4 mg of Sodium-24 remain, we will use the formula;

A = A_o(½^(t/T_½))

Where t is the time that 4 mg of Sodium-24 remain.

Thus;

4 = 64 × ½^(t/15)

Divide both sides by 64 to get;

4/64 = 2^(t/15)

0.0625 = ½^(t/15)

In 0.0625 = (t/15) In 0.5

-2.7726 = (t/15) × -0.6931

t = (-2.7726 × 15)/-0.6931

t = 60 hours

Miya flips a coin and rolls a 6-sided number cube labled 1-6 and records tge outcome. About how many times is she likely to flip heads and roll a 3 out of 48 trials

Answers

Answer:

4 times

Step-by-step explanation:

Sample space :

6 sided cube = (1, 2, 3, 4, 5, 6)

Coin = (H, T)

Probability = required outcome / Total possible outcomes

Probability of head (H) = P(H) = 1 /2 = 0.5

Probability of 3 = P(3) = 1 /6 = 0.166666

Probability of heads and 3 on a single try = p(H) * p(3) = 0.5 * 0.166666 = 0.083333

Hence, expected number of times this is likely to occur in 48 tries :

0.083333 * 48 = 4
