Answer:

The density of the pine log is 0.2842 pounds per inch.

Step-by-step explanation:

To calculate the density of an object, you must divide its mass by its volume (radius times height). Thus, given that the pine log that has a 5-inch radius and is 30 inches long, while its weight is approximately 42.63 pounds, the following calculation must be performed to determine its density:

X = 42.63 / (30 x 5)

X = 42.63 / 150

X = 0.2842

Thus, the density of the pine log is 0.2842 pounds per inch.

Answer:

a) 4800 bacteria

b) [tex]y(t) = 300(4)^t[/tex]

c) 754 bacteria

Step-by-step explanation:

A bacteria culture starts with 300 bacteria and doubles in size every half hour.

This means that the number of bacteria after t periods of half hour is given by:

[tex]y(t) = 300*(2)^{t}[/tex]

(a) How many bacteria are there after 2 hours?

2 hours is 2*60/30 = 4 periods of 2 hours, so this is y(4).

[tex]y(4) = 300*(2)^{4} = 300*16 = 4800[/tex]

(b) How many bacteria are there after t hours?

It doubles every half hour, so each hour, it is multiplied by 4. Then

[tex]y(t) = 300(4)^t[/tex]

(c) How many bacteria are there after 40 minutes?

40 minutes is 40/30 = 1.33 periods of half hour. So this is y(1.33).

[tex]y(1.33) = 300*(2)^{1.33} = 754[/tex]

Answer:

Yes

Step-by-step explanation:

If 2/5kg fills one third, let's multiply 2/5kg by 3 to find out how much soil the conatainer can hold.

(2/5kg)(3) = 9/5kg = 1.8kg

1.8kg>1kg, so the answer is yes

Answer:

C

Step-by-step explanation:

This is the only possible correct answer because the other three all show the final price as 0.90x, which is correct since the price is the normal one minus 10 percent. C is incorrect because it suggests the normal price has a 10% tax, or extra value on it.

Answer:

Emily's inequality x < 6 is correct because the number of hours is less than or equal to.

Emily's number line is incorrect The endpoint is filled in and the number line is greater than the endpoint.

Step-by-step explanation:

Emily's Model:

                                       x < 6

<----|----|----|----|----|----⊕----|----|----|----|----|----|----|----|---->

     1    2   3    4   5    6   7   8   9   10  11   12  13  14

What Emily's model should look like to make the number line true:

                                       x < 6

<----|----|----|----|----|----О----|----|----|----|----|----|----|----|---->

     1    2   3   4    5    6     7     8   9   10  11  12  13  14

Answer:

Take 148÷37. Which equals 4. The answer is C.

Answer:

Step-by-step explanation:

Because if you add 22 and 8 together you get 30 and once you get 30 you subtract 10 gaining 20 and then you divide 20 getting [tex]2\sqrt{5}[/tex].

22+8= 30

30-10= 20

[tex]\sqrt{20} = 2\sqrt{5[/tex]

Answer:

  x = 10

Step-by-step explanation:

The angle bisector divides the sides proportionally.

  (2x +1)/12 = (x +4)/8

  2(2x +1) = 3(x +4) . . . . . multiply by 24

  4x +2 = 3x +12 . . . . . . . eliminate parentheses

  x = 10 . . . . . . . . . . . . . . subtract 2+3x

Answer:

£15347.07

Step-by-step explanation:

Given data

Amount=£19064.67

% decrease=19.5%

let us find the value of 19.5%

=19.5/100*19064.67

=0.195*19064.67

=£3717.6

Hence the new Amount after the decrease is

=19064.67-3717.6

=£15347.07

Answer:

y = -1/3x

Step-by-step explanation:

Since the line has to be parallel, that means it will have the same slope. So, we use the given point and slop to solve for the new y= mx + b using the equation y - y = m( x - x)

m= -1/3    x = 3   y = -1

y + 1 = -1/3(x - 3)

y + 1 = -1/3x + 1

y = -1/3x

Answer:

11

Step-by-step explanation:

Do kcf (keep,change,flip)

First, covert 2 3/4 into an improper fraction

Then after you do that you get 11/4

so you do the equation 11/4 ÷ 1/4

when you do kcf it would be 11/4 × 4/1=

11/4×4/1=44/4 simplify divide both by 4 = 11
