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?
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

what is the value of n
Answer:
n=5
Step-by-step explanation:
take 29 add to 56 then divided by 17
Answer:
5
Step-by-step explanation:
56 = 17n - 29
-17n = -29 - 56 [remember: when u transfer a positive number it becomes negative and when u transfer a negative number it becomes positive]
-17n = -85
n = -85/-17

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°.
Which statement is true about this triangle?
BC=3 in.
BC=4 in.
BC=5 in.
The length of BC¯¯¯¯¯ cannot be measured.
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°
[tex]BC=\sqrt{4^2+4^2-2*4*4*cos60}[/tex]
BC = 4 in
Answer:
bc = 4

Write the equation for the line
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

Mai skated x miles, and Clare skated 35 3 5 farther than that. Write an equation to represent the relationship between the distance Mai skated (x) and the distance Clare skated (y). BoldItalicUnderline
Answer:
[tex]y = \frac{3}{5} + x[/tex]
Step-by-step explanation:
Given
Represent Mai's distance as x and Clare's distance as y
[tex]Mai = x\ miles[/tex]
[tex]C = \frac{3}{5}[/tex] farther than Mai
Required
Determine the relationship between both
[tex]C = \frac{3}{5}[/tex] farther than Mai
Substitute x for Mai
[tex]C = \frac{3}{5}[/tex] farther than x
Express as a mathematical expression:
[tex]C = \frac{3}{5} + x[/tex]
Recall that Clare's distance is represented by y.
So, we have:
[tex]y = \frac{3}{5} + x[/tex]
Hence, the relationship is: [tex]y = \frac{3}{5} + x[/tex]
Answer: Mai skated x miles, and Clare skated 3/5 farther than that. Write an equation to represent the relationship between the distance Mai skated (x) and the distance Clare skated (y).

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

Complete question :
Lilian purchased a violin form smash music stores. It regularly sold for $670, but wa son slaw for 10% off. She also had to pay 8% sales tax. She bought it on the installment plan and paid 15% of the total cost with tax as a down payment. Her payments were $58 per month for one year. What is her sales tax?
Answer:
$48.24
Step-by-step explanation:
Given that:
Sales price = 670
Discount = 10% off
Sales tax = 8%
Discounted price = (1 - 0.1) * 670
Discounted price = 0.9 * 670 = $603
Hence, purchase price = $603
Hence, sales tax = 8% of purchase price
8% of $603
0.08 * 603 = $48.24
