Pease answer ASAP

Answer:

5x + 16

Step-by-step explanation:

the first thing you do in this equation is to distribute the 2 into x + 6

you get

2x + 12 + 3x + 4 = ?

then you must put the 2x and the 3x together

5x + 12 + 4

and you can then add the 12 and 4

5x + 16

Answer:

C

Step-by-step explanation:

"At least 75" means Erin needs a score that is 75 or more.  Her score should be equal to or greater than 75.

The number line that shows this is C because the point at 75 is filled in (showing that 75 is included), and the ray (arrow) extends to the right indicating numbers larger than 75.

The product of the length and width must be equals to 20. Therefore, it could be 4 and 5(or reverse) or  10 and 2(or reverse).

where

l =length

w = width

h = height

Therefore,

v = 100 inches³

h = 5 inches

Therefore, the length and the width can be as follows;

divide both sides by 5

lw = 100 / 5

lw = 20

Therefore, the product of the length and width must be equals to 20. Therefore, it could be 4 and 5(reverse) or  10 and 2(reverse).

The last statement : "The customers surveyed are not representative of all the customers who come to the mall".

For instance, if only half the mall want the mall to open earlier, but then out of the 20 people that we randomly picked, 15 of them are in the half, we could go to a wrong conclusion that most of the people want the mall to open earlier.

to fix the problem, you might just want to increase the area of the survey next time, or get more people to be in it, etc.

The most cookies Heidy can make is 36 cookies.

To know how many cookies Heidy can make, you have to take into account the following information:

12 cookies need the following ingredients:

In the case in which Heidy has more ingredients, we must carry out the following operations:

Divide the quantities, in the reference quantity we have:

According to the above, we must take into account the lowest value of all because if that ingredient is enough, we can infer that the rest of the ingredients also.

So the number of cookies Heidy can make are:

12 × 3.5 = 42

Heidi can make a maximum of 36 biscuits with the available ingredients.

Given that the Available ingredients are:

Butter: 500 g

Flour: 700 g

Sugar: 250 g

Required ingredients per batch:

Butter: 125 g

Flour: 200 g

Sugar: 50 g

Let's calculate the maximum number of batches Heidi can make for each ingredient:

Batches based on Butter:

500 g butter / 125 g butter = 4 batches

Batches based on Flour:

700 g flour / 200 g flour = 3.5 batches

=3 batches

Batches based on Sugar:

250 g sugar / 50 g sugar = 5 batches

Therefore, the greatest number of biscuits Heidi can make is the number of batches multiplied by the number of biscuits per batch:

Number of biscuits per batch = 12 biscuits

Number of batches = 3 batches

Greatest number of biscuits Heidi can make = Number of biscuits per batch × Number of batches

Greatest number of biscuits Heidi can make = 12 biscuits/batch × 3 batches = 36 biscuits

So, Heidi can make a maximum of 36 biscuits with the available ingredients.

Step-by-step explanation:

Answer:

104%

Step-by-step explanation:

(275 × p) / 100 = 286

((275 × p) / 100) × 100 = 286 × 100

275p = 28600

275p / 275 = 28600 / 275

p = 104

Percent Increase = 104

Answer:

==> 104%

Step-by-step explanation:

Working Out

The problem we are solving is:

Work out the percentage increase between 275 and 561.

Difference is 561 - 275 = 286.

Divide the difference between the original number:

286 / 275 = 1.04.

Multiply by 100 to change to a percentage:

1.04 x 100 = 104%.

This number is positive so we have a percentage increase of 104%.

Answer:

43°

Step-by-step explanation:

A triangle has a total angle of 180° and we can use it to find the answer.

The attachment is a visualization of the triangle.

In order to find angle T, we can use the triangle formula to find t.

[tex] {180}^{o} = r + s + t[/tex]

By substituting r and s, we will get

[tex] {180}^{o} = {85}^{o} + {52}^{o} + t[/tex]

Hence, we can find T, which is

[tex]t = {180}^{o} - {85}^{o} - {52}^{o} = {43}^{o} [/tex]

The indicated partial derivative of z is; 1.

According to the question:

The given value of z is; Z = u, v, −w

Hence, it follows that;

d³z = ∂/∂u(u) + ∂/∂v(v) - ∂/∂w(w)

Ultimately, the value of ∂³z is; 1.

Answer:

Step-by-step explanation:

Permutation and combination is very important in our daily life. By using it, we can already distinguish or identify the different possible ways of the things that we get or have.

Permutation refers to the different possible arrangements of a set of objects and order is very important while combination is the number of ways of selecting from a set when the order is not important.

Which of the following situations does NOT illustrate combination?

a. Selecting 2 songs from 10 choices for an audition piece

b. Fixing the schedule of a group of students who must take exactly 8 subjects

c. Enumerating the subsets of a set

d. Identifying the lines formed by connecting some given points on a Plane

In this situations, we can determine if it is all combination or not. Let's find it out.

a. Selecting 2 songs from 10 choices for an audition piece - this situation does not require any order or arrangement. That's why letter A illustrates combination.

b. Fixing the schedule of a group of students who must take exactly 8 subjects - in fixing and arranging the schedule of a group of students, it must have to be in order so that they can determine their subjects every hour or period and everyday. The schedule must be arrange properly so that the students must not get confused. That's why in this situation the order and arrangement is very important and it shows the concept of permutation not combination.

c. Enumerating the subsets of a set - in enumerating we are not required to make it in order. We can list the subsets of a set in any order, that's why letter C illustrates combination.

d. Identifying the lines formed by connecting some given points on a Plane - we can connect different and many given points in any directions to have a Plane. It is not required to connect all the points in order so that we can form a Plane. Also, in identifying the lines, we can write and list it in any order and that the order is not important.

In conclusion, the situation that does NOT illustrate combination is situation B, because it is more on the concept of permutation not in combination.

Step-by-step explanation:

in percentage its 20.83.

mark me brainlist

According to the p-value, the correct option regarding the decision of the test hypothesis is:

v. No, because 0.283 > 0.05.

At the null hypothesis, we test if the proportion is still of 0.53, that is:

[tex]H_0: p = 0.53[/tex]

At the alternative hypothesis, we test if it has increased, that is:

[tex]H_1: p > 0.53[/tex].

In this problem, the p-value is of 0.283 > 0.05, hence there is not sufficient evidence to conclude, at the significance level of a = 0.05, that the proportion of all car owners in the United States who own American-made cars has increased from what it was ten years ago, which means that option V is correct.

The way that something appears or is set out.

Answer:

1 234 567,89

The American variation that we had become used to is commas for the thousands separator and a full stop for the decimal point.

1,234,567.89

In programming, I have only ever seen the use of the full stop for the decimal mark, and no thousands separator. However when printing numbers for humans to read, its important to use the thousands separator and to use a number format that the largest group of readers will easily understand.

If your readers are South African, this handy JavaScript function will format your numbers correctly with 2 decimal places, which is mostly useful for displaying currency values. This code is a modified version of this script.

function za_format(number) {

number = parseInt(number).toFixed(2);

number += '';

var x = number.split('.');

var x1 = x[0];

var x2 = x.length > 1 ? ',' + x[1] : '';

var rgx = /(\d+)(\d{3})/;

while (rgx.test(x1)) {

x1 = x1.replace(rgx, '$1' + ' ' + '$2');

}

return x1 + x2;
