3x^2-4x+1, match the following
il63 [147K]

Answer:

x = variable

3 = coefficient

1 = constant

3x^2-4x+1 = algebraic expression

2 = degree

Step-by-step explanation:

variables are typically the letters in equations (usually x and y)

coefficients are the numbers attached to the variables

constants don't have any variables attached

algebraic expressions are the full expression

degrees are the small numbers in the top right corners on either constants, variables or coefficients

Hope this helps!

What is the lateral and surface area? I will give the brainliest if you answer correctly and no links or you will be reported ​
jeyben [28]

Answer:

Lateral: 560

Surface Area: 560 + 96\sqrt{3}

Step-by-step explanation:

Well, we know that the lateral area is just the surface area subtracted by the hexagon base of the figure. Thus, if we (1) find the area of one of the triangular faces and multiply by 6, we get the lateral area. And then, if we (2) add the area of the hexagonal base, we get the surface area.

Let's do (1) first to get the lateral area

They mention that the base of one of the triangular faces is 8 and its height (which is the slant height) is 20. So the area is simply 20 * 8/2 = 80

Then, we multiply by 6 because there are 6 of these triangles and get 560

So the lateral area is 560

Let's do (2) next to find the surface area

If we add the area of the hexagonal base to 560, we obtain the surface area

The hexagon is a regular hexagon with a length of 8. Now, the area of a hexagon 3\sqrt{3}  * s^2 /2 where s is the side. We can obtain this formula if we separate the hexagon into 6 equilateral triangles.

Plugging in 8 for s we get 96\sqrt{3}

So the surface area is 560 + 96\sqrt{3}

A person must score in the upper 7% of the population on an admissions test to qualify for membership in society catering to hig
vladimir2022 [97]

Answer: The minimum score a person must have to qualify for the society = 147.4

Step-by-step explanation:

Let X be the test scores.

As per given,

X is normally distributed.

Mean (\mu) = 110

\sigma=5

$$\begin{array}{l}\quad P(z>2)=0.07 \\\therefore \quad 1-P(z

The minimum score a person must have to qualify for the society = 147.4

a snack cart sells lemonade for $2 and hot dogs for $5. the vendor sold 86 items today for a total of $330.which equation is tru
DaniilM [7]
There are two equations in the system of equations in this problem.
Let x = lemonade and y = hot dogs

First equation
x + y = 86
This says that the total sold hot dogs and lemonades add up to 86 sold.

Second equation
2x + 5y = 330
This says that $2 for each lemonade, $5 for each hot dog. The total amount earned is $330.

Only these two equations are true and needed.
