Complete the following sentence about the rate of change in the number of bacteria in minutes.

a/a+b is the same as a/(a+b). This is because the division of two numbers is represented by the symbol '/', and when a and b are being divided, it is written as a/b.

In this case, a and b are being divided by a+b, so it is written as a/(a+b). This is known as a fraction, which represents a ratio of two numbers. This fraction represents the proportion of a to the total of a+b. The numerator (a) represents the part of the total that you are interested in, and the denominator (a+b) represents the entire quantity.

The missing number of points scored in the last basketball game is 13.

What is the meaning of the data set?

A data set is a grouping of data. A data set refers to one or more database tables in the case of tabular data, where each column of a table represents a specific variable and each row corresponds to a specific record of the data set in question.

Given that,

the number of points scored in the last basketball game by each player on the Dragons basketball team are 7, 5,8,11,7,5,?.

Assume that the missing point is x.

The sum of points is 7+5+8+11+7+5+x = 43 + x.

The number of points is 7.

The mean is the sum of points/number of points

= (43+x)/7

Given that the mean of the data set is 8 points.

Therefore,

(43+x)/7 = 8

Multiply both sides by 7:

43+x = 8×7

43 + x = 56

x = 56 - 43

x = 13

We calculate the percentage of black paint in each mix by dividing the amount of black paint by the total amount of paint and multiplying by 100. Julian's mix has a black paint percentage of 52.94% while Harper's mix has a black paint percentage of 58.33%. Therefore, Harper's gray paint will be darker.

The first step to determine whose gray paint will be darker is to calculate the percentage of black paint each student has in their mix. To find this, one must know that the percentage is calculated by dividing the part (the quantity of black paint) by the whole (the total amount of paint) and then multiplying by 100.

Julian's percentage of black paint: (9 cups black / 17 total cups) * 100 = 52.94%

Harper's percentage of black paint: (7 cups black / 12 total cups) * 100 = 58.33%

Since the percentage of black paint correlates with the darkness of the gray paint, Harper's gray paint will be darker because it contains a higher percentage of black paint.

Step-by-step explanation:

The equations equivalent to 2.3p – 10.1 = 6.5p – 4 – 0.01p are;

The correct answer is option B and C

2.3p – 10.1 = 6.5p – 4 – 0.01p

collect like terms

2.3p - 6.5p + 0.01p = -4 + 10.1

-4.19p = 6.1

p = 6.1/-4.19

p = -1.46

2.3p – 10.1 = 6.5p – 4 – 0.01p

= 2.3p – 10.1 = 6.49p – 4

Given options:

2.3p – 10.1 = 6.4p – 4

False

2.3p – 10.1 = 6.49p – 4

True

230p – 1010 = 650p – 400 – p

divide through by 100

= 2.3p – 10.1 = 6.5p – 4 – 0.01p

True

23p – 101 = 65p – 40 – p

False

2.3p – 14.1 = 6.4p – 4

The area of a (equilateral) triangle with side 8cm is 16√3cm^2.

What is a triangle and its types?

A figure which has a three-sided closed figure is called a triangle.

Types

Equilateral Triangle

A triangle where all the sides are the same is called an equilateral triangle.

Isosceles Triangle

When two of the sides of a triangle are the same it’s called an isosceles triangle. It’s a hard one to spell, but an easy one to recognize!

Scalene Triangle

In our last triangle, none of the sides have the same length, so this is called a scalene triangle.

Acute Triangle

when the largest angle in the triangle  is less than 90, that is an acute triangle. Just remember that acute angles are less than 90 degrees.

Right Triangle

When the largest angle is exactly 90 degrees. You might remember that a 90-degree angle is a right angle, so this triangle is a right triangle.

Obtuse Triangle

When largest angle is more than 90 degrees, this is an obtuse angle, so we call this triangle an obtuse triangle.

Area of an equilateral triangle whose side is 8 cm is √3/4*a^2 where

a=8

= √3/4*8^2

= √3/4*64

= √3*16

The two angle of the right triangle are found as 30 degrees and 60 degrees.

Less than 90 degrees is considered an acute angle. Right angles have a 90 degree angle. More than 90 degrees is found in obtuse angles.

By using angle sum property of right angle triangle:

x + 2x + 90 = 180

3x = 90

x = 30 (one angle)

2x = 60 (Other angle)

What is the graph of a function?

The graph of a function is a visual representation of the relationship between the input values (x-coordinates) and the output values (y-coordinates) of the function. In other words, it is a visual representation of the function's rule.

The graph of a function can take many different forms, depending on the function's rule. Linear functions, for example, will produce a straight line on the graph.

i) 2y - 4x < 8 can be solved by adding 4x to both sides and then dividing by 2, giving:

y < 2x + 4.

ii) -4y > -x + 12 can be solved by adding x to both sides and then dividing by -4, giving: y < x/4 - 3.

iii) | x + 3 | = y, you can split this into two cases:

i. x + 3 = y

ii. -(x + 3) = y

iv) |2x – 6| + 2 = y, you can split this into two cases:

i. 2x - 6 + 2 = y

ii. -(2x - 6) + 2 = y

We can use these equations to plot the graph on a coordinate plane.

The additive inverse of 2 /- 7 is -2 /+ 7.

An additive inverse is a number that when added to the number in question, the sum is equal to zero. This can be expressed by the formula x + (-x) = 0, where x is the number in question. In this case, x is 2 /- 7. So, when 2 /- 7 is added to its additive inverse, -2 /+ 7, the sum is 0. This can be expressed mathematically as 2 /- 7 + (-2 /+ 7) = 0. Calculating this equation, we get 2 /- 7 + (-2 /+ 7) = -2 /+ 7 + (-2 /+ 7) = -4 /+ 14 = 0. Therefore, the additive inverse of 2 /- 7 is -2 /+ 7.

Step-by-step explanation:

They are both supplementary to the same angle. (<SVW)

Otherwise, you could just see if they are across from each other.

Answer:

Step-by-step explanation:

if x were starting at 0, we would have

y = (x - 7)×7 = 7x - 49

but we start at x = 57. We need adjust for these extra 57 to get the above equation.

so, it

y = (x - 57 - 7)×7 = (x - 64)×7 = 7x - 448

so, for

y = (x - 64)×7

I choose x = 57

y = (57 - 64)×6 = -7×7 = -49

for

y = 7x - 448

I choose x = 58

y = 7×58 - 448 = 406 - 448 = -42

from this form we get the y-intercept (the y- value when x = 0) : -448

The probability of both events occurring is P(A ∩ B) = P(A)P(B) = 0.16^2 = 0.0256.

The event of getting a "2" and the event of getting a "5" on the first roll of a die are mutually exclusive events because they cannot both occur in the same trial. The probability of either of these events occurring is P(A) = 0.16, and the probability of both events occurring at the same time is P(A ∩ B) = 0.00.

The event of getting a "2" on the first roll and the event of getting a "5" on the second roll of a die are independent events. This can be confirmed using the formula P(A ∩ B) = P(A)P(B). The probability of getting a "2" on the first roll is P(A) = 0.16 and the probability of getting a "5" on the second roll is P(B) = 0.16.
