Step-by-step explanation:

Like terms are those which have exactly the same variables ... In 3xy2 , 3 is the coefficient, xy2 is the literal coefficient.

An expression is a way of writing a statement with more than two variables or numbers with operations such as addition, subtraction, multiplication, and division.

In the expression 5a + 2 + 7 + 6a

5a and 6a are like terms.

5 and 6 are coefficients of a.

What is an expression?

An expression is a way of writing a statement with more than two variables or numbers with operations such as addition, subtraction, multiplication, and division.

Example: 2 + 3x + 4y = 7 is an expression.

We have,

5a + 2 + 7 + 6a

We  can simplify as,

Add like terms.

A local carnival sells two different containers of popcorn, as shown below.


Both containers have the same height, and the bases of the containers are congruent. Which statement best describes the relationship between the volumes of the two containers?

A. Container B will hold twice the volume of popcorn of Container A.
B. Container B will hold three times the volume of popcorn of Container A.
C. Container B will hold the same volume of popcorn as Container A.
D. Container B will hold 1/3 times the volume of popcorn of Container A.

Answers

The answer would be C since the formula for volume is lwh or bh. With this info, you know that the bases are congruent which means they are the same, as well with the height. So you just multiply the height by the base and they should be the same.

2. The net below shows equilateral triangles. What is the total surface area of the triangular pyramid in square feet?

Answers

Answer:

65^2

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

#2:

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

Step-by-step explanation:

The distance that a object covered in time was measured and recorded in the table. What equation would describe this motion?
y = 2x
y = 4x + 2.5
y = 4x + 4
y = 1.5x + 4.0

Answers

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 drives a taxi cab and receives $200 a day plue $0.25 for every mile he drives. He is saving up for a new laptop that costs about $1800. If Hayden drives an average of 300 miles per day, how many days will he have to drive to save enough money to buy the laptop?

Answers

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.
