16.8 is 10% of what number? Someone help TWT

Answers

Answer:

168

Step-by-step explanation:

16.8 = 10%

x = 100%

To get to 100%, you have to multiply 10 by ten and 16.8 by 10. Like this:

16.8 = 10%                   original equation

16.8 (10) = 10% (10)      * both sides by 10

168 = 100%                  simplify

Answer:

A-(x+4,y-5)

B- move 1 unit left and 7 units down

Step-by-step explanation:

A- 4 units right is x so

(x+4,y__)

5 units down is y so

(x+4,y-5)

B- move 1 unit left and 7 units down

because (x-1,y__) is going left because of the subtraction sign and its the x-coordinate, and (x-1,y-7) is down because its a Y-coordinate and sub so its going down.

TIP- Going left/down is always subtract/negative going right/up is positive/addition.

Answers

Question:

A package of 8 pens costs $1.09. Milo’s work to find the unit price of the pack is shown below.

8p/$1.09 =

8÷$1.09  =

$7.34

Where did Milo make his first error?

Answer:

He wrote the unit rate incorrectly.

Step-by-step explanation:

Given

[tex]Pens = 8[/tex]

[tex]Cost = \$1.09[/tex]

Required

Determine Milo's error

First, we need to solve for the unit price; then compare our results with Milo's

[tex]Unit\ Price = \frac{Cost}{Pens}[/tex]

[tex]Unit\ Price = \frac{\$1.09}{8}[/tex]

[tex]Unit\ Price = \$0.13625[/tex]

Comparing the calculation with Milo's:

We can see that he made wrong calculations i.e. in other words, he solved the required incorrectly

Find the slope. Explain what the slope and y-intercept means for the situation. Be sure to use your labels when explaining the real-life situation.

Answers

Answer:

Slope: 25, y-intercept: 0

Step-by-step explanation:

Take any two points. I'm going to take (3, 75) and (4, 100).

How to find slope: change in y/change in x

Change in y --> 100 - 75 = 25

Change in x --> 4 - 3 = 1

25 ÷ 1 = 25.

Slope is 25

Since 3 · 25 = 75, the y-intercept is 0.

The y-intercept stands for how much money someone gets for working 0 days, so they get $0 for working/whatever situation they're in for 0 days.

Answer:

y=4x+3

Step-by-step explanation:

The slope is positive 4 and the y intercept is 3

Answer:

y = 4x + 3

Step-by-step explanation:

y = mx + b

m is the slope and b is the y-intercept

The slope is how much units it goes up/down while how much units it goes left/right from one point to the other. So two points we'll use for reference is (-1, -1) and (0, 3). You want to make sure the points u choose are whole numbers cause they're easier to tell. So the distance between those 2 points if it goes to the right once and goes up 4 units. Left/right is x and up/down is y, y/x is how u write the slope. So it's 4/1 which is just 4

The y-intercept is just where the line intercepts on the y-axis. The line goes through the point 3 on the y-axis, so it's 3

Input the numbers in the equation and it's y = 4x + 3

On a piece of paper, use a protractor and a ruler to construct △ABC with AB=4 in., AC=4 in., and m∠A=60°.

The length of BC¯¯¯¯¯ cannot be measured.

Answers

Answer:

BC 4 in

Step-by-step explanation:

The steps for construction;

Using a ruler draw line AB 4 inches  and label the end points A and BAt point A , using a protractor, measure angle 60° and mark with point. Draw a line from A passing through this point extending to a length of 4 inchesMark that point C.Using the ruler, join point C and B and measure BC.

From calculation, length BC can be found by the formula;

[tex]BC=\sqrt{a^2+b^2-2*a*b*cosA}[/tex]------where a=b=4 in , cos A = cos 60°

A human bone is made up of water 1/4 and 9/20 minerals, and the rest is living tissue. What decimal represents the amount of a human bone that is living tissue?

Answers

Answer:

0.3

Step-by-step explanation:

First you need to add 1/4 and 9/20, and you would get 7/10. That only leaves 3/10, which as a decimal is 0.3.

The decimal that represents the amount of a human bone that is living tissue is 0.3

What is the fundamental principle of multiplication?

Multiplication is the mathematical operation that is used to determine the product of two or more numbers. If an event can occur in m different ways and if following it, a second event can occur in n different ways, then the two events in succession can occur in m × n different ways.

We are given that human bone is made up of water 1/4 and 9/20 minerals, and the rest is living tissue.

First we need to add 1/4 and 9/20,

Thus we would get 7/10.

That only leaves 3/10, which as a decimal is 0.3.

The decimal that represents the amount of a human bone that is living tissue is 0.3
