88 is what percent of 550?
Answer:
16%
Step-by-step explanation:
Is means equals and of means multiply

Given an arithmetic progression with u21 = 65 and d = -2, find the value of the first term.
Answer:
105 = a
Step-by-step explanation:
L = a + (n-1)*d
n = 65
d = -2
L = u21 = 65
65 = a + (21 - 1)*(-2) Divide by - 2
65 = a + 20*-2 Multiply 20 times - 2
65 = a - 40 Add 40 to both sides
65+40 = a Combine
105 = a
The value of the first term is 105
The nth term of an arithmetic sequence is gotten by using the formula:
= a + (n - 1)d
The value of the 21st term which has been given in the question is 65 and the common difference is -2. This will be:
a + (n - 1)d = 65
a + (21 - 1)d = 65
a + 20d = 65
Since d, common difference = -2
a + 20d = 65
a + 20(-2) = 65
a - 40 = 65
a = 60 + 45
a = 105
In conclusion, the value of the first term is 105

1. At Chesterfield Town Center, Alex is at the Barnes and Noble at coordinates (-10,9) and Jeff is at the Macy's which is at (4,-6). They decide to meet for lunch in the food court which is halfway between their locations. What are the coordinates of the food court?
Answer:
(-1,-1)
Step-by-step explanation:
The easiest way I know how to explain it is you put the numbers on a line for instance
-6, -5,-4,-3,-2,-1,0,1,2,3,4
and the number in the very middle of the y then for x
-10,-9,-8,-7,-6,-5,-4,-3,-2,-1,0,1,2,3,4,5,6,7,8,9
and then again you use the midpoint for the x
because they are trying to meet each other half way you are trying to find the midpoint.

A music recording studio charges a flat fee of $45.00 plus $8.50 per hour to record your music.Another recording studio charges $27.59 plus $11.00 an hour to record music.Find the number of hours for which costs are the same
Let, after t hours costs are the same.
Mathematical equation of charges taken by first studio :
[tex]y=45+8.5t[/tex]
Mathematical equation of charges taken by second studio :
[tex]y=27.59+11t[/tex]
So,
[tex]45+8.5t=27.59+11t\\\\2.5t=17.41\\\\t=6.964\ hours[/tex]
Therefore, after 6.964 hours cost of both studio is same.
Hence, this is the required solution.
There was 75 runners to start a race. In the first half of the race 1/5 of them dropped out. In the second half of the race 3/5 of the remaining runners dropped out. How many runners finish the race?
Answer:
24 runners finish the race
Step-by-step explanation: 1/5 of 75 =15
75 - 15 =60
3/5 of 60 = 36
60 -36 =24
1) The product of a number and -7 is 63
2) 10 subtracted from a number is 15
3) two-fifths of a number is -12
4) 8% of a number is 20
5) the sum of twice a number and 17 is -1
6) nine less than the product of a number and -4 is 35
Step-by-step explanation:
let the no. be x
for 1,
x× -7 = 63
or, x= 63 ÷ -7
or, x = -9
therefore -9times -7 is 63.
for 2
by question
x -10= 15
or, x = 15+10
or, x = 25
therefore 25 minus 10 equals 15.
for 3
by question
(2/5) of x = -12
or, x = -12×(5/2)
r, x= -6×5
or, x = -30
therefore 2/5 of -30 is -12
for 4
by question,
8%of x = 20
or, 8x/100=20
or, 8x = 20×100
or, x = 2000÷8
or, x= 250
therefore 8% of 250 is 20.
for 5
by question,
2x+17 = -1
or, 2x = -1 -17
or, 2x = -18
or, x = -18 ÷ 2
or, x =-9
therefore -9 times 2 plus 17 equals -1.
for 6 dont know

(2a-1) = 42/3
2a-1=14
2a=13
a=7.5
I hope this helps you out!
Answer:
put 6 over 1 then look for the LCM of 7 and 1 the LCM is 7 then ask yourself how times does seven go into 7 one time right so multiply 1 by 3(2a - 1) then ask yourself how many times does 1 go into 7 it goes 7 times right multiply 7 by 6 so your equation is like this 3(2a - 1) = 42 open the bracket so it will be 6a - 3 = 42 collect the like terms so 3a = 42+3, 3a =45 , divide both sides by 3 so x =15

I understand the answers are
2i(square root) 3
and 3i(Square root) 5
I need to understand *how* i comes into the equation and what it does step by step.
Answer:
You got the answers correct.
Step-by-step explanation:
i is equal to the square root of -1. This is helpful to know because you have to sort of "take out" the negative square root of 1 before simplifying these. the square root of negative 12 is the same thing as the square root of -1 times the square root of 12. Since i is the square root of -1, you can replace that part with i. So, it is i times the square root of 12. We can simplify the square root of 12 by doing the square root of 4 times 3, which is 2 root 3, like you were saying. Then, this value is multiplied by i, so the final answer is 2i (root) 3. This same thing applies to the second portion. The square root of 45 is 3 root 5, and you have to multiply that by i since it is a negative square root. Therefore, that is 3i (root) 5.
