Hey!

Hope this helps....

~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

For Question 2: 6+3+n=12

This is because we know that there is a combined total of 12, so it has to equal 12 (which cancels out C), we also know that the question is not saying anything that implys that we are multiply anything thing (which cancels out B, and D), so we are only left with A.) 6+3+n=12


For Question 4: 2 (Fraction 2 over 3)

This is because when we substitute all those choices in for y, we get...

2/(3*(3/8)) ~ 1.77778

2/(3*(5/12)) = 1.6

2/(3*(11/12)) ~ 0.727273

2/(3*(8/3)) = 0.25

^^^^ I got 8/3 from A (b/c) > ((A*c)+b)/c

(And we know 1/4 = 0.25)

QUESTION POSTED AT 17/10/2019 - 09:25 AM

If you have 12% withheld for federal taxes, 7% for state taxes, and FICA is 7.65%, how much are your involuntary withholdings in all if your gross pay was $1,375.00 and your net income was $725.00?

Total known withholdings = federal + state + FICA + involuntary
= (12 + 7 + 7.65) % of 1,375 + Involuntary
Net income = gross - withholdings
$725.00 = $1,375.00 - [(12 + 7 + 7.65) % of 1,375 + Involuntary]
Solve for involuntary
725=1375-0.2665×1,375-inv
725=1375-366.4375-inv
Involuntary=1,375−366.4375−725
Involuntary=283.56

How do I determine the points E and M

Relabel the spot that you have as M. (The reason we are keeping this coordinate is because it is correct just labeled wrong. It lines up perfectly with G and O both)

G is in the wrong spot, you have it in (2,2) it needs to go down 4 places to the coordinates (2, -2)

E will be located directly under O and directly across from G. So, it will be at the coordinates (-4, -2)

A line has a slope of 1/4 and passes through point 0.4-1/2. What is the value of the y-intercept?

Linear equation with the form y=mx+b

m=1/4 (given) & it passes through (0.4, - 0.5)

Let's calculate b; -0.5 = (1/4)(0.4) + b
-0.5 =0.25(0.4) + b
-0.5 - 0.1 = b  -0.6
y= 0.25x - 0.6
y intercept is calculated for x=0
Then y intercepts =-0.6

Which set of integers is a Pythagorean triple? 3, 5, 6 5, 12, 13 15, 9, 17 6, 8, 12

Answer:

The set of integers which form a Pythagorean triple is:

5,12,13

Step-by-step explanation:

We are asked to find the set of integers such that they form a Pythagorean triplets.

Three integers a,b,c are said to form a Pythagorean triplets if they satisfy the property:

c^2=a^2+b^2

1)

3,5,6

6^2=36

and

3^2+5^2=9+25\\=34\neq 36

Hence option: 1 is incorrect.

2)

5, 12, 13

13^2=169

and

5^2+12^2=25+144=169

This means:

13^2=5^2+12^2

Hence, option 2 is correct.

3)

15,9,17

17^2=289

Also,

15^2+9^2=225+81=306\neq 289

Hence, option 3 is incorrect.

4)

6,8,12

12^2=144

and:

6^2+8^2=36+64=100\neq 144

Hence, option 4 is incorrect.

Graph the pH function using the graphing utility. Then answer the questions. What is the pH of lemon juice that has a hydrogen ion concentration of 0.01 moles per liter? The pH is??

Answer:

pH = 2

Step-by-step explanation:

To graph the pH function :

The range of the pH function varies from 1 to 14

And the concentration of hydrogen ion goes from 0 to 1

Taking pH value on y-axis and concentration of hydrogen ion on x-axis, The resultant graph is attached below :

Given : Concentration of hydrogen ion = 0.01

Now, pH = -log(0.01)

pH=-\log(\frac{1}{100})\\\\pH=-(\log 1 - \log 100)\\pH=-(0-2)\\\implies\bf pH=2

QUESTION POSTED AT 17/10/2019 - 09:22 AM

The prism is partially filled with 150 cubic cm of sand what fraction of the prism is filled by the sand

Since 150 can't go into 250 twice as a whole, you know that the percentage is over 50% . To find the percentage (I think, bad memory) You need to find the difference or increase between the two. 250 / 150 = 100 Then divide the increase or difference by the original number (As in 150) then multiply that by 100. The percentage would be 66% 

Hope this helps, though would ask someone again just to be sure

QUESTION POSTED AT 17/10/2019 - 09:20 AM

A 20-foot ladder is leaning against a tree. The bottom of the ladder is 12 feet away from the bottom of the tree. Approximately how high up the tree does the top of the ladder reach?

We want to use the Pythagorean theorem to find the missing length of the right triangle described in the word problem.

The Pythagorean Theorem is a^2 + b^2 = c^2, where a and b are the side lengths of the right triangle, and c is the hypotenuse.
If we know the lengths of two sides of a triangle, we can always find the length of the third side using this formula.

We're given the lengths of one of the sides (12) and the hypotenuse (20). We plug these numbers into our equation and then solve for x.
(x represents the how high the ladder reaches)

x^2 + 12^2 = 20^2
x^2 + 144 = 400
x^2 + 144 - 144 + 400 - 144
x^2 = 256

Now, find the square root of each side of the parenthesis.

√x^2 = √256
x = 16.

The answer is 16.

If there's anything you don't understand, I would highly recommend going to the website Khan Academy and watch his videos regarding it, he explains things much better than I ever could.

Hope this helps!!

How do you do a 3-step algebra equation?

The goal of all algebra equations is to isolate the variable. In 3 step you should first make sure both variables are on the same side. To do that make sure you use the inverse.
For example:
6a + 9 = 3a + 15
because 3a is positive you're going to want to subtract it.
6a + 6 = 3a + 15
-3a         -3a
_______________
3a + 6 = 15

Now it's a 2 step equation and you solve it on from there.
