From the statement, we know that the bacteria population doubles every x hours. We write the population as a function of x as:

Where:

• P₀ = initial population,

• x = time in hours.

If we consider P₀ = 1, we get the following formula:

The area of the figure shown below is equivalent to 88 square units.

A parallelogram is a straightforward quadrilateral with two sets of parallel sides in Euclidean geometry.

The opposite sides of a parallelogram are congruent and the sum of their adjacent side is equivalent to 180 degrees.

The formula for calculating the area of a parallelogram is expressed as;

Area = length * breadth

Area = x * h

Area = 8 * 11

Area = 88 square units

Hence the area of the parallelogram above is 88 square units.

The price of one canadian dollar in US dollars is 91 cents or 0.91 US dollars.

It is given that the price of a US dollar is 1.10 Canadian dollars in the market.

Thus we can say that,

1.10 Canadian Dollar = 1 US Dollar

∴ 1 Canadian Dollar = [tex]\frac{1}{1.10}[/tex] US Dollars

⇒ 1 Canadian Dollar = 0.91 US Dollars

Now we know that 1 US Dollar = 100 cents

∴ 0.91 US Dollars = 0.91 x 100 = 91 cents

Hence the value of 1 Canadian Dollar is 0.91 US Dollars or 91 cents.

The ratio 9:4 in the form n:1 is 2.25:1.

The given ratio is 9:4.

The ratio is defined as the comparison of two quantities of the same units that indicates how much of one quantity is present in the other quantity.

We need to write the given ratio in the form n:1

Divide the given ratio by 4

9/4 : 4/4

The number or children tickets are 24 and adults tickets are 9.

Adult tickets (x) cost $7.50 and tickets for children (y) cost $3.50. The equation will be:

7.5x + 3.5y = 139.5

There are 33 tickets. This will be:

x + y = 33

x = 33 - y.

Recall 7.5x + 3.5y = 139.5

Substitute for x.

7.5(33 - y) + 3.5y = 139.5

247.5 - 7.5y + 3.5y = 139.5

-4.5y = 139.5 - 247.5

4.5y = 108

y = 108/4.5

y = 24

Number of children ticket = 24

Adult tickets = 33 - 24 = 9

A. If two figures have the same shape, then they are congruent.

Answer:

10m

Step-by-step explanation:

Perimeter means adding up all of the sides of a shape.

One property of a square is that all lengths of a square are the same.

We also know squares have 4 sides.

Lets set up an expression to solve the length for each side with variable S representing the length of a side:

4 * S = 40

Divide each side by 4:

S = 10

Therefore, each side of the square has a length 10m

On solving the linear equation 12.5 = 2x + 4.5, we find that cost of first type of candy is $4 per pound

Linear equation is an equation containing one unknown variable with power one and constants.

The standard form of an linear equation in one variable x is :

ax + b = 0 , where a, b are constants

x= -b/ a is solution if this equation or we can solve this equation by adding or subtracting, multiplying, dividing same number to both sides.

Given that there are two types of candies one is of  x dollars per pound

and one is of $1.50 per pound

Cost of 2lb of candy that costs x dollars per pound = 2 × x  = $ 2x

Cost of 3lb of candy that costs  $1.50 per pound  = 3 × 1.5 = $ 4.5

2lb of one type of candy and 3lb of other type of candy are mixed to form a mix of weight 2lb + 3lb = 5lb

The cost of one pound of mixture = $2.50

The cost of 5lb of such mixture = $ 5× 2.50 = $ 12.5

Cost of 5lb mix = Cost of 2lb candy of first type + Cost of 3lb candy of second type

⇒ 12.5 = 2x + 4.5

Subtract 4.5 from both sides,

⇒ 12.5 - 4.5 = 2x

⇒ 8 = 2x

Divide both sides by 2

⇒ 4 = x

Therefore, the cost of first type of candy is $ 4 per pound

The length of the Boca Grande Causeway = 13,000 feet.

Repeated addition of the same number is made easier by multiplying the numbers. When we need to merge groups of similar sizes, we employ it. For instance, if there are 5 baskets, each containing 4 apples, we can use multiplication to get the total number of apples, which is 5 x 4 = 20 apples.

We can rapidly determine the total number of things by multiplying. When multiplying, we'll consider the number of groups with similar sizes and the number of items in each group.

Given: The boca grande causeway in florida = 1 4/9 times golden gate bridge

Length of the Golden Gate Bridge = 9000 feet

Thus the length of the Boca grande causeway = 1 4/9 × 9000

= 13/9 × 9000

On further solving we get

= 13 × 1000

= 13,000 feet .

120/8 but then we have to subtract it from 3

that would be 117/8 then we simplify it 14 -5/8.

Part B: first it would be 2 plus 2 and that's 4 and then make 4 into a fraction

4/4 we simplify that 1 0/4.

Because x = -1 is a real root, you can divide

(x^3 + x^2 + 4·x + 4)/(x + 1) = x^2 + 4

Roots of x^2 + 4 are

x^2 + 4 = 0

x^2 = -4

x = ± 2·i

All real and complex roots are

8 × [tex]10^5[/tex] is 200 times greater than 4 × [tex]10^3[/tex]  as according to multiplying and dividing as per the scientific notation of multiplication and division.

A kind of representation of number which is some power of 1/10 can also be expressed in as easily in scientific notation.

1/10 = [tex]10^{-1[/tex]  (“ten to the minus one power”)

More generally, the expression “[tex]10^{-n[/tex]” (where n is a whole number) means (1/10) n. Thus

[tex]10^{-3[/tex] = [tex]\frac{1}{10}^{-3}[/tex]

= 1/1000

[tex]10^{-8[/tex] = [tex]\frac{1}{10}^{-8[/tex]

= 1/100,000,000

Scientific notation was invented to help scientists (and science students) deal with very large and very small numbers, without getting lost in all the zeros.

Herein this question

8 × [tex]10^5[/tex] can also thus be written as 2 x 4 × [tex]10^5[/tex]. On dividing with 4 × [tex]10^3[/tex] we get 2 x [tex]10^2[/tex]. Thus, it is 2 x [tex]10^2[/tex] i.e., 200 times larger than 4× [tex]10^3[/tex].

The expression “10n”, where n can be stated as a whole number, simply means that “10 is raised to the nth power,” or in other words, a number that is got by using 10 as a factor n times.

You can also notice that the number of zeros that are present in the ordinary decimal expression is absolutely equal to the power to which thus 10 is raised.

If any kind of number is expressed in words, first we have to write it down as an ordinary decimal number and then we have to convert it. Thus, the value “ten million” becomes 10,000,000. There are a total of seven zeros, so in powers of ten notation ten million is written [tex]10^7[/tex].
