Answer:

Step-by-step explanation:

let x be the population

so we have ,

2x= 6h

?= 3 days or 3×24h

by cross multiplication we have

2x× 72h= 6h×?

?= 2x×72/6 = 24x

So, in three days the bacteria will b 24 times current population.

Answer:29

Step-by-step explanation:

d[AB]=|45-16|=29

A number line is the representation of numbers in real order.

The difference between the consecutive numbers in a number line is always positive.

The length AB is 29.

AB = 29 is our answer.

It is the representation of numbers in real order.

The difference between the consecutive numbers in a number line is always positive.

We have,

A is at point 16.

B is at point 45.

Now,

The distance between A and B.

= B - A

= 45 - 16

= 29

Thus,

The length AB is 29.

AB = 29 is our answer.

Answer:

(-2, -4)

Step-by-step explanation:

Given the coordinate (x, y), if rotated 90degrees, counterclockwise, the resulting coordinate will be (-y, x)

For the coordinate (-4, 2)

When rotated 0 degrees  counterclockwise, the resulting coordinate will be at (-2, -4)

Note that the coordinates were switched and the x negated

Answer:  each cookie was $0.94

Step-by-step explanation:

5.00 - 1.89 = 3.11

3.11 - 1.23 = 1.88

1.88 divided by 2 = 0.94

Answer:

20°

Step-by-step explanation:

ok so if 40 degrees is on one side its also on the side parallel from it

a straight line = 180 degrees

so 180 - 40 = 140

so 7x =140

we now divide 7 on both sides and get x=20 because the 7 cancels out

180 -40 =140

7x = 140

7x/7 =140/7

x=20

Answer:

By the math, x = 10°

Here's my issue though, the top angle is x - 15°. That would be an angle of -5° which is impossible.

Step-by-step explanation:

x - 15 + 2x + 25 + 180 - 4x = 180°

combine like terms:

3x - 4x + 190 = 180°

-x = -10°

x = 10°

Answer:

50 pack

[tex]\$0.01[/tex]

Step-by-step explanation:

Number of packs at Costco = 30

Cost of 30 packs at Costco = $10.82

Number of packs at the other place = 50

Cost of 50 packs = $17.25

Cost of one pack when 30 packs are bought

[tex]\dfrac{10.82}{30}=\$0.36[/tex]

Cost of one pack when 50 packs are bought

[tex]\dfrac{17.25}{50}=\$0.35[/tex]

It is better to buy the 50 pack.

Difference in the unit prices = [tex]0.36-0.35=\$0.01[/tex].

The value of the expression  21 ÷ 3 + (8 - 2 ÷ 2) is 14.

To simplify the expression 21 ÷ 3 + (8 - 2 ÷ 2).

we need to follow the order of operations (PEMDAS/BODMAS), which stands for Parentheses/Brackets, Exponents/Orders, Multiplication/Division, and Addition/Subtraction.

The expression inside the parentheses should be solved first.

8 - 2 ÷ 2.

First, divide 2 by 2, which equals 1.

Then, subtract 1 from 8: 8 - 1 = 7.

Now, we have 21 ÷ 3 + 7.

Divide 21 by 3, which equals 7.

Finally, add 7 + 7, which equals 14.

Therefore, the simplified expression 21 ÷ 3 + (8 - 2 ÷ 2) equals 14.
