Answer:

Step-by-step explanation:

1/3 of the original

Step-by-step explanation:

one piece is TWO times longer than the other one. if you break it in half you have three pieces that are all the same size

Using confidence interval concepts, it is found that:

In this problem, the interval is (19,27), hence the point estimate is:

P = (19 + 27)/2 = 23.

The margin of error is:

M = (27 - 19)/2 = 4.

Answer:

24

Step-by-step explanation:

You can use a simple equation for this:

c=chickens, r=roosters

c=10+2r, as "chickens is TEN MORE than TWICE the number of roosters,"

we can then do;

10+2r+r (the original number of roosters)=31

3r=21

r=7

BUT, WE'RE NOT LOOKING FOR ROOSTERS!

10+2r=24

Answer:

25.12

Step-by-step explanation:

C = 3.14*2*4
C = 25.12

Answer: 7 more than 2 times a number

Step-by-step explanation:

To describe 2m it would by 2 times m since it is multiplication

When describing a variable simply call it a number

Now we have "2 times a number", but we still need to incorporate the +7

To represent +7 we can say "7 more" since that represents addition

So we end up with "7 more than 2 times a number"

Answer:

2 times m + 7

The equation, that Sebastian can use to find p, the number of pencils each friend will receive is given by: Option C: 6p = 30

You can represent the unknown amounts by the use of variables. Follow whatever the description is and convert it one by one mathematically. For example if it is asked to increase some item by 4 , then you can add 4 in that item to increase it by 4. If something is for example, doubled, then you can multiply that thing by 2 and so on methods can be used to convert description to mathematical expressions.

For this case, we're given that:

Now, that means, if we collect all those p pencils, then they should be 30 in count.

Sum of pencils from 6 friends = p + p + p + p + p + p = 30

or

[tex]6 \times p = 30[/tex] (since p was added 6 times itself, so we write it as 6 times p)

we don't write the "×" sign, (Using sign of multiplication is often hidden if there are non numeric symbols and numbers being multiplied are written together) Thus, the equation is 6p = 30 (well both equations are same).

Thus, the equation, that Sebastian can use to find p, the number of pencils each friend will receive is given by: Option C: 6p = 30

Answer:C

Step-by-step explanation:

Answer:

5/8 is smaller.

Step-by-step explanation:

A ratio is just a different type of fraction, a 5:8 ratio means 5/8 which is 0.625. A 7:9 ratio equals 7/9 which is 0.777777

Then to compare them you see which is smaller or bigger.

0.77777  is bigger than 0.625 so we know that 0.77777777 which was the 7:9 ratio is the bigger one.

Answer:

Area of the rectangle = 20 square units

Area of left triangle = 8 square units

Area of right triangle = 6 square units

Area of whole figure = 34 square units

Step-by-step explanation:

Alright, area of a rectangle is Base · Height. The base of the rectangle is 5 units and the height is 4 units. 5 · 4 = 20 square units.

Area of a triangle is (Base · Height)/2. The triangle on the left is 4 units tall and 4 units wide. 4 · 4 ÷ 2 = 8 square units.

The triangle on the right is 4 units tall and 3 units wide. 4 · 3 ÷ 2 = 6 square units.

To get the area of the whole figure, you can just add the area of all three shapes. 20 + 8 + 6 = 34 square units.

Hope this helps! :)

Answer:

Rectangle's area;

Length: 4

Width: 5

Formula for area of rectangle;

A = L*W

Replace values:-

A = 4(5)

A = 20.

Left triangle's area;

Base = 4

Height: 4

Formula for area of triangle;

A = BH x 1/2

Replace values:-

A = 4(4) x 1/2

A = 16 x 1/2

A = 16/2

A = 8.

Right triangle's area;

Base = 3

Height: 4

Formula for area of triangle:

A = BH x 1/2

Replace values:-

A = 3(4) x 1/2

A = 12 x 1/2

A = 12/2

A = 6.

Add all the areas we've found so far to get the figure's total area:

20 + 8 + 6

= 34.

Answer:

113.04 ft^2

Step-by-step explanation:

area of circle formula = [tex]\pi r^{2}[/tex]

in this case, we are taking π as 3.14, so it is 3.14 x [tex]r^{2}[/tex]

Radius = half of diameter

radius = 12 / 2 = 6

[tex]6^{2}[/tex] = 36 (because 6 x 6 = 36)

3.14 x 36 = 113.04

Therefore, our answer is 113.04 ft squared (because it is area)

The number of hours it would take for the bacteria count to grow from 75 to 120 is 2 hours.

The first step is to determine the rate of increase of the bacteria. The formula that can be used is:

g = (FV / PV)^(1/n) - 1

Where:

(75/40)^(1/3) - 1 = 23.3%

The formula that can be used to determine the number of hours it would take for the population to grow from 75 to 120 is:

Number of hours =  (IN FV / PV) / r

(IN 120/75) / 0.233 = 2 hours
