PLEASE WHOEVER TELLS ME THIS (CORRECT) ANSWER ILL MAKE ANOTHER QUESTION WITH 30 POINTS
Answer:
6y - 1/2y
Step-by-step explanation:
So...
We need to multiply by 5y/5y to write -4 as a fraction with a common denom.
2/5y - 4 * 5y/5y + 7 - 9/10y
Simplify...
Combine the -4 and 5y/5y
2/5y + -4(5y)/5y + 7 - 9/10y
Combine the numer over the common denom
2 - 4(5y)/5y + 7 - 9/10y
Simplify the numerator by factoring 2 out of then 2 out of -4 * 5y and then 2 out of 2(1) + 2 (-2 * 5y)
2(1) - 4 * 5y/5y + 7 - 9/10y
2(1) + 2(-2 * 5y)/5y + 7 - 9/10y
2(1 - 2 * 5y)/5y + 7 - 9/10y
Now multiply -2 by 5
2(1 - 10y)/5y + 7 - 9/10y
Now we do the same 5y/5y with 7
Combine...
2(1 - 10y)/5y + 7(5y)/5y - 9/10y
Combine more.
2(1 - 10y) + 7(5y)/5y - 9/10y
Now we need to simplify more
Distributive property application
2 * 1 + 2 (-10y) + 7 * 5y/5y - 9/10y
Multiply 2 by 1
2 + 2(-10y) + 7 * 5y/5y - 9/10y
-10 by 2
2 - 20y + 7 * 5y/5y - 9/10y
Then 7 by 5
2 - 20y + 35y/5y - 9/10y
Then -20y by 35y
2 + 15y/5y - 9/10y
Now we have to multiply 2 + 15y/5y by 2/2
2+ 15y/5y * 2/2 - 9/10y
Now we write with a common denom of 10y and multiply with a factor of 1
(2 + 15y) * 2/5y * 2 - 9/10y
Multiply 2 by 5
(2 + 15y) * 2/10y - 9/10y
Combine again
(2 + 15y) * 2 - 9/10y
Simplify again with the distrib property
2 * 2 + 15y * 2 - 9/10y
Multiply 2 by 2
4 + 15y * 2 - 9/10y
Then 2 by 15
4 + 30y - 9/10y
Then subtract 9 from 4
30y - 5/10y
Factor out 5 from 30y - 5...
5(6y) -5/10y
5(6y) - 5/10y
Factor 5 out of -5
5(6y) + 5(-1)/10y
Then 5 out of 5(6y) + 5(-1)
5(6y - 1)/10y
Now we cancel more common factors which is 5 here
6y - 1/2y
The thiciness of a fingernail is about 1
The thickness of a fingernail is about 10^-5 inch
From the complete question, we have the following parameter
Thickness = 1/100000 inch
To represent the thickness in standard form, we do the following:
Express the thickness as a decimal
Thickness = 0.00001 inch
So, the standard form would be:
Thickness = 1 * 10^-5 inch
This gives
Thickness = 10^-5 inch
Hence, the complete statement is:
The thickness of a fingernail is about 10^-5 inch

A library shelf contains seven books. Three books are math books and four books are science books. In how many ways may the books be arranged on the shelf so that all the math books will be together
There are 720 different ways to arrange the books.
In how many ways we can order the books?
Here we know that there are a total of 7 books, 3 of math and 4 of sciences.
We know that the 3 math books must be together, so first let's analyze this element.
The number of permutations of these 3 books is 3! = 3*2*1 = 6
Now we have 5 elements, 4 books of science and a "group of math books."
So there are 5 positions in which the group of math books can be, and for the four science books we have 4! = 4*3*2*1 = 24 permutations.
The total number of different combinations is given by the product of the numbers we found above:
combinations = (permutations of math)*(possible positions of math)*(permutations of science).
Combinations = 6*5*24 = 720

The amount of pocket money will be double the amount previous day. He will start first day with R1. He can use this saving for his matric dance.
3.1 Write the information as a sequence.what is the sequence of this information?
The formula for obtaining the value of a term of a sequence is given as a
as a recursive formula.
Responses:
The information as a sequence is; R1, 2·R1, 4·R1, 8·R1, 16·R1, ...The sequence of the information is a geometric sequenceHow is the given information expressed as a sequence?The amount of pocket money Smith gets = 2 × The amount he gets in the previous day
The amount Smith gets on the first day = R1
Required:
The given information expressed as a sequence.
Solution:
The amount of money smith gets can be expressed as follows;
Amount he gets on day 1 = R1
On day 2, R2 = 2·R1
On day 3, R3 = 2·R2 = 2·2·R1 = 4·R1
On day 4, R4 = 2·R3 = 2·2·2·R1 = 8·R1
On day 5, R5 = 2·R4 = 2·2·2·2··R1 = 16·R1
The information written as a sequence is therefore;

A rectangle has a length of 26 yards less than 8 times it’s width. If the area of the rectangle is 682 square yards, find the length of the rectangle.
Answer:
Length is 62 yards
Step-by-step explanation:
A = wL
L = 8w-26
682 = w(8w-26)
682 = 8w^2 -26w
0 = 8w^2 - 26w - 682
Use the quadratic formula (it's really hard to type it but just look it up if you want to see the explanation)
w = 11
L = 8(11) - 26 = 62 yards
Check: 62(11) = 682

Please help, I am so confused. If anyone understands this please help
Answer:
12 ft
Step-by-step explanation:
It is sometimes helpful to start from what you are given and see what develops.
Here, angle B is 30°. That means angle CAB is 60° (the acute angles of a right triangle are complements). AL bisects that 60° angle, meaning two things:
ΔALC is a 30°-60°-90° triangle, so you know its side ratios∠LAB = 30°, so ΔALB is isosceles and AL = LBThe side ratios of a 30°-60°-90° triangle are 1 : √3 : 2, so AL is 2 times the length of CL.
AL = 2 × (6 ft) = 12 ft
We know that AL = LB, so LB = 12 ft.
Dominic and Candice are both selling cookie dough for a fundraiser. Although Dominic has already sold 5 tubs, Candice hasn't sold any yet. If Dominic starts selling 6 tubs per day and Candice begins selling 7 tubs per day, they will eventually sell the same amount of cookie dough. How many tubs will each sell? How many days will that take?
Answer:
5 days, 35 tubs
Step-by-step explanation:
We can create an equation.
Let d be the number of days it will take.
Note that in all Dominic will have sold 6d + 5 tubs, and Candice 7d.
So, if 6d - 5 = 7d then d = 5.
So, it will take 5 days, and each will have sold 6 * 5 + 5 = 7 * 5 = 35 tubs of cookie dough.

Riley makes a necklace for his sister. Twelve beads take up 5 inches of string.
How many beads fit on 1 foot of string?
Hey how was your day? What did you do today?
Answer:
28.8
If rounded 28
Step-by-step explanation:
If every 12 beads takes up 5 inches that means that 1 foot (12 inches) would be divided by 5 (12/5) (A. 2.4) and then multiplied by 12. which would give you 12.8 or since you cant have 28.8 beads, you can only put on 28 when rounded.

Step-by-step explanation:
he starts with 13 folds some number "f" of them and has some number "n" still to do
The linear equation that links N and F in the previously stated condition is N + F = 13.
What is a linear equation?
Because a straight line emerges when we attempt to display the graph of the provided linear function, a linear equation is known as linear.
Given Alan has 13 shirts to fold. Let N be the number of shirts he would have left to fold after folding F of them.
The linear equation that satisfies the above statement is
N + F = 13
therefore, N + F = 13 is the linear equation that relates N and F in the above-given condition.

Jennifer mixes 600ml of orange juice with 900ml of apple juice to m
ake a fruit drink. Write the ratio of apple juice to orange juice in its simplest form.
Answer:
2:3
Step-by-step explanation:
So OJ is 600ml and AJ is 900ml
we can divide both by 100 so
600÷100= 6
900÷100= 9
Ratio is now 6:9 but we can simplify it more by 3
so 6÷3=2 and 9÷3=3
So therefor ratio is 2:3
