Answer:

B 11%

Step-by-step explanation:

The total number of marbles is

12+4+2 = 18

P( blue) = number of blue marbles / total marbles

            = 2 blue/ 18 total

            = 1/9

              =.11111

             = 11.11%

Answer:

C), or y = 200(1.18)^x, because we have 200 bacteria to start with and 1.18 because if you multiply something by 1.18 that is essentially 118% more than the number, or 18% more than the number.

The cost of one cupcake for Option B is 2.75

Step-by-step explanation:

66 ÷24=2.75

Answer:y = 1.5x + 4.0

Step-by-step explanation:

This is because the equation relates the distance traveled (y) to the time elapsed (x) through a linear relationship with a slope of 1.5, which represents the object's speed in meters per second, and a y-intercept of 4.0 meters, which represents the initial position of the object at time zero.

I'm pretty sure.

The equation that describes the motion of the object is y = 2x (option a)

Let's calculate the slope (m) using the values from the table. We take any two points (x₁, y₁) and (x₂, y₂) from the table:

(x₁, y₁) = (1, 2.0)

(x₂, y₂) = (5, 10.0)

The slope (m) is given by:

m = (y₂ - y₁) / (x₂ - x₁)

m = (10.0 - 2.0) / (5 - 1)

m = 8.0 / 4

m = 2.0

Now that we have the slope (m), we can determine the equation:

y = mx + b

Using one of the points from the table (1, 2.0) and the calculated slope (m = 2.0), we can solve for the y-intercept (b):

2.0 = 2.0 * 1 + b

2.0 = 2.0 + b

b = 2.0 - 2.0

b = 0

So, the Answer is option (a) y = 2x

Hayden will have to drive for approximately 7 days to save enough money to buy the laptop.

Given:

Daily base pay = $200

Earnings per mile driven = $0.25

Cost of the laptop = $1800

Average miles driven per day = 300

The basic arithmetic operations have been used to solve this question

1. Calculating the total earnings per day.

Total earnings per day = Daily base pay + (Earnings per mile driven × Average miles driven per day)

Total earnings per day = $200 + ($0.25 × 300)

Total earnings per day = $200 + $75

Total earnings per day = $275

2. Determining the number of days required to save enough money for the laptop.

Number of days = Cost of the laptop ÷ Total earnings per day

Number of days = $1800 ÷ $275

Number of days ≈ 6.545 (rounded to the nearest whole number)

Therefore, Hayden will have to drive for approximately 7 days to save enough money to buy the laptop.

Step-by-step explanation:

To make use of the given formula for amount remaining, we need to know the original amount (300 mg), the elapsed time (12 h), and the half-life of the substance of interest (8 h).

Using the given formula with the relevant values, we have ...

  A = (300 mg)·(1/2)^(12/8)

Step-by-step explanation:

if you woulndt mind giving me brainliest im trying to rank up, only if u dont mind.

#1:

Between 8 cm and 9 cm

Work:

SA = 6s^2  

390 = 6 s^2

390/6 = 6s^2 /6

65 = s^2

sqrt(65) = s

s = 8.06

The total surface area of the triangular pyramid is 107 * square feet.

What is a triangular pyramid?

Take a triangle. This is a base. Now take 3 triangles such that each of them are connected to one-one side of the first triangle and when they're taken together, they form a closed object, called as a triangular pyramid.

We are given that;

The length of median from outer triangle to side of the inner triangle is 8 ft

Side of inner equilateral triangle is 12 ft

Now,

First, we can find the height of the outer equilateral triangle using the Pythagorean theorem:

a is half the length of the side of the inner triangle (6 ft), m is the length of the median (8 ft), and b is the length of the side of the outer triangle (unknown).

a^2 + (m/2)^2 = b^2

b^2 = 6^2 + 8^2/4

b^2 = 36 + 4

b^2 = 40

b = sqrt(40)

b = 2 * sqrt(10)

So the height of the outer triangle is:

h = b * sqrt(3)/2

h = sqrt(30)

Now we can find the area of each equilateral triangle using the formula:

A = (sqrt(3)/4) * s^2

For the inner triangle:

A_inner = (sqrt(3)/4) * 12^2

A_inner = 36 * sqrt(3)

For the outer triangle:

Now we can find the area of the base, which is just the area of the inner equilateral triangle:

A_base = A_inner

A_base = 36 *

Finally, we can find the surface area of the triangular pyramid by adding the areas of the four triangles and the base:

SA = A_inner + 3 * A_outer + A_base

Answer:

Answer:

6:1 and 12:2. cuz if u multiply each, you will eventually get 24:4

Step-by-step explanation:

If the result of the two ratios are same, then they are said to be equivalent ratio.

The ratio which is equivalent to the given ratio are 6:1 and 12:2. Thus the option A and C is the correct option.

Equivalent ratio is the ratio which is same in the value as the original ratio but the numerator and denominator is different for both the ratios.

Given information-

The ratio given in the problem is,

[tex]24:4[/tex]

Let r is the ratio, then it can be written as,

[tex]r=\dfrac{24}{4}\\[/tex]

Simplify it,

[tex]r=\dfrac{6}{1}[/tex]

[tex]r=6:1[/tex]

Check all the options which is equivalent to the ratio 6:1.

[tex]6:1[/tex]

Which is equal tot he given ratio. Thus the option A is correct option.

[tex]8:4[/tex]

Let r is the ratio, then it can be written as,

[tex]r=\dfrac{8}{4}\\[/tex]

Simplify it,

[tex]r=\dfrac{2}{1}[/tex]

[tex]r=2:1[/tex]

Which is not equal to the given ratio. Thus the option B is incorrect option.

[tex]12:2[/tex]

Let r is the ratio, then it can be written as,

[tex]r=\dfrac{12}{2}\\[/tex]

Simplify it,

[tex]r=\dfrac{6}{1}[/tex]

[tex]r=6:1[/tex]

Which is equal to the given ratio. Thus the option C is correct option.

[tex]15:3[/tex]

Let r is the ratio, then it can be written as,

[tex]r=\dfrac{15}{3}\\[/tex]

Simplify it,

[tex]r=\dfrac{5}{1}[/tex]

[tex]r=5:1[/tex]

Which is not equal to the given ratio. Thus the option D incorrect option.

Hence the ratio which is equivalent to the given ratio are 6:1 and 12:2. Thus the option A and C is the correct option.
