find the sum and difference of 5/8 and 3/8
Answer:
see below
Step-by-step explanation:
5/8+ 3/8
Since the denominator is the same, we can add the numerators
(5+3) /8 = 8/8 = 1
5/8- 3/8
Since the denominator is the same, we can subtract the numerators
(5-3) /8 = 2/8 = 1/4
Answer:
Sum=1
Difference= 1/4
Step-by-step explanation:
I added them together to find the sum.
I subtracted them to find the difference.
Line A has a slope of -4/3. Line B is perpendicular to Line A. What is the slope of Line B?
Answer:
The answer is 3/4
Step-by-step explanation:
If two lines in perpendicular, then the slope has a relation as slope1 * slope2 = -1. Then if line 1 has slope -4/3 then -4/3 * x = -1, then x = 3/4 which is the slope for the second line.
one end of the cable is attached to the top of the flagpole and the other end is attached 6 feet away from the base of the pole if the height of the flagpole is 12 feet, find the length of the cable.
Answer:
13.42 ft. to the nearest tenth of a foot
Step-by-step explanation:
The length of the cable is the hypotenuse of a right triangle. You know the two legs, 6 and 12, so let the length of the hypotenuse = h. Then,
[tex]h^{2} = 6^{2} + 12^{2} = 36 + 144 = 180\\h = \sqrt{180} = 13.42[/tex]
13.42 ft. to the nearest tenth of a foot

add 126.99 to 8.8893
you get ~135.87
Answer:
8.89
Step-by-step explanation:
Take the cost of the item times the tax rate to find the amount of tax
126.99 * 7%
Change to decimal form
126.99 * .07

The volume of a storage pod that is shaped like a cube is 1728 cubic feet whats the area of the floor space
So to find the area of floor space we need to know the sides..
So we dont know the side and so to find the side of the cube we need to- (see the above pic)
So by doing this we get 12 as the side...
Now we need to know the area of floor space(as the shape is square) so area is s²= 12×12=144
So therefore area is 144cm² (of floor space)
The absolute value inequality equation |2x – 1| > 3 will have what type of solution set?
A)
Intersection
B)
Union
C)
All real numbers
D)
No solution
The absolute value of the inequality |2x -1| >3 will have a union type of solution set.
How do we solve the absolute value of an inequality equation?The absolute value of an inequality equation can be solved by applying the absolute rule that says:
If |u| > a, a > 0, then u < - a or u > awhere;
the "or" functionality symbolizes the union between the solution sets.Given that:
|2x - 1| > 3Applying the absolute rule, we have:
= 2x - 1 < - 3 or 2x - 1 > 3
= 2x < -4 or 2x > 4
= x < -4/2 or x > 4/2
= x< -1 or x > 2 which denotes the union of between the solution sets.

Answer:
A, B, D
Step-by-step explanation:
The "form factor" in the attached is the difference between the sum of the squares of the short sides and the square of the long side. If that difference is 0, the Pythagorean theorem is satisfied, and the triangle is a right triangle. When the difference is positive, the triangle is acute; negative, the triangle is obtuse.
As you can see, all but the third triangle are right triangles.

The slope of the line that passes through the point (2,4) and (3,8) is
Hi! Your answer is m = 4 or slope is 4.
Make sure to read an explanation for a better and clear understanding to your problem.
Any questions about my answer and explanation can be asked through comments! :)
Step-by-step explanation:
To find a slope of a line with given two coordinate points, we can do by using rise over run or slope formula which is:
[tex]\large\boxed{m=\frac{y_2-y_1}{x_2-x_1}}[/tex]
The boxed formula is the slope formula. The changes of y over the changes of x. This can be called "rate of change".
From (2,4) and (3,8). We substitute the given coordinate points in the formula.
[tex]\huge{m=\frac{8-4}{3-2}}\\\huge{m=\frac{4}{1}}\\\huge{m=4}[/tex]
Hence, the slope is 4.
Additional Note
m-term comes from y = mx+b where m is defined as slope in slope-intercept form. Therefore, m = slope.Hope this helps!

Proofs in the picture
The value of y is 225 when x is 50 from the given graph.
What is Coordinate System?Arrangement of reference lines or curves used to identify the location of points in space is called as Coordinate system.
We need to find the value of y when x is fifty.
In the given graph we have to draw a perpendicular line at x =50.
Now we have to check the point where the perpendicular line touches the graph curve.
Take the corresponding value of y.
When x is 50 the value of y is nearly to 225.
Hence, the value of y is 225 when x is 50.

Keshawn painted 12 game pieces,
each in the shape of square pyramids.
Each pyramid's base was 2 inches
long, and each triangular face was
4 inches tall. What was the total area
that Keshawn painted
A 20 in.
B 32 in.
C 192 in.
D 240 in?
Answer:
240in
Step-by-step explanation:
Total surface area of a square based pyramid is expressed as
TSA = 1/2pl + B
p is the perimeter of the base
p = 4L
p = 4(2)
p = 8in
l = 4in
B is the base area = 2 * 2 = 4in^2
TSA = 1/2 * 8 * 4 + 4
TSA = 16 + 4
TSA of one game piece = 20in
Since we have 12 game pieces, total surface area will be 20 * 12 = 240in

Answer:
x= -1
Step-by-step explanation:
Given data
We have the expression as
(x+1)/(x+1)= 1/2
let us first cross multiply
2(x+1)=(x+1)
2x+2=x+1
collect like terms
2x-x=1-2
x= -1
