hi there
40.3
Step-by-step explanation:
28547=100%
11504=R
11504 x 100=1150400/28504
1150400/28504=40.29 = 40.3
11504/28547 = 0.40x 100 = 40 %

Answer:

Step-by-step explanation:
If x represents the number of dimes, then 2x will represent twice the number of dimes. This is the number of quarters, since there are twice as many quarters as dimes.
There are 6 more nickels than dimes, so the number of nickels is 6 more than x. It is (x+6).
If we use the monetary values in cents, then the total of all coins is ...
25(2x) +10(x) + 5(x+6) = 485 . . . . . . matches choice D

What’s the correct answer for this?
Answer:
B
Step-by-step explanation:
Parallel lines this means they have the same slope -4
The coordinate is (0,0) which means x=0 and y=0
So,
Finding b(y-intercept) for the parallel line
y=mx+b
Where y=0, m=-4 and x=0
0=(-4)(0)+b
0=0+b
So
b=0
So slope intercept form of the parallel line is
y=(-4)x+(0)
y=-4x
At a sale this week, a sofa is being sold for $153.60 .This is a 76% discount from the original price. What is the original price?
Answer:
$21473.33
Step-by-step explanation:
Let the original price be x
76% discount gives $153.60
This means 24/100 * x = $153.60
X= 153.60 * 100 /24 = $21473.33
The original price of the sofa is $21473.33.
What is discounted price?Discount is the difference in price between the selling price of an object and the price listed on the object marked price.
Given that, a sofa is being sold for $153.60, which was on the 76% discount.
Let the original price be x,
x - 76% of x = $153.60,
⇒ 24/100 · x = $153.60
⇒ x = 153.60 · 100 /24 = $21473.33
Hence, the original price of the sofa is $21473.33.

What is the solution for the equation x2+4=3x+8
Answer:
Step-by-step explanation:
Let's solve your equation step-by-step.
x2+4=3x+8
Step 1: Subtract 3x+8 from both sides.
x2+4−(3x+8)=3x+8−(3x+8)
x2−3x−4=0
Step 2: Factor left side of equation.
(x+1)(x−4)=0
Step 3: Set factors equal to 0.
x+1=0 or x−4=0
x=−1 or x=4
Answer:
x=−1 or x=4

{ala > 2}
{ala > 4}
{ala > 8}
{ala > 10}
Answer:
b) a > 4
Step-by-step explanation:
Step(i):-
Given inequality equation
2 a + 4 > 12
subtracting ' 4' on both sides , we get
2 a + 4 -4 > 12 -4
2 a > 8
Step(ii):-
dividing '2' on both sides , we get

Two lengths of a triangle are shown.
6
ft
6
ft
[Not drawn to scale]
Which could be the length of BC?
Answer:
11 ft
Step-by-step explanation:
Given the two lengths of a triangle as
AB = 6ft
AC = 6ft
This is an isosceles triangle because only 2 sides are equal.
In an isosceles triangle, the sum of 2 (sides) lengths must be greater than the other length.
Therefore, let's assume the following:
i) AC + AB > BC
6 + 6 > BC
12 > BC (BC is less than 12)
BC < 12
ii) BC + AC > AB
BC + 6 > 6
BC > 6 - 6
BC > 0
Therefore the range of values for BC =
0 < BC < 12
Since BC must be bigger than one of the lengths and it must also be less than the sum of the 2 sides. The length of BC could be 11 because it is less than (6+6) 12 and greater than 6.

choose a number between 67 and 133 that is a multiple of 2,8 and 16 .
Answer:
80
Step-by-step explanation:
Since 2 and 8 are factors of 16, you only need to find a multiple of 16 in between 67 and 133 which is simple. I chose 80.
Answer:
128
Step-by-step explanation:
It's asking you to find a number between 67 and 133 that you could divide by 2, 8 and 16 and won't get a remainder.
128 can be divided by 2, 8 and 16 without a remainder.

This problem is same as finding the least common multiple (LCM) of 3 and 4.
3 = 3
4 = 2 x 2
=> LCM = 3 x 2^2 = 12 (3 appears once, 2 appears twice)
=> After 12 hours, two bell P and Q ring simultaneously.

14.
N = Noe
kt
No = inital amount of C-14 (at time
t = 0)
N = amount of C-14 at time t
k = 0.0001
t = time, in years
find the age of the skull to the nearest year
Answer:
about 2357 years
Step-by-step explanation:
You want to find t such that ...
0.79 = e^(-.0001t)
Taking natural logs, we get ...
ln(0.79) = 0.0001t
ln(0.79)/-0.0001 = t = 2357 . . . years

A) In terms of s, the area of the base is ____________ .
B) The formula for the volume of a pyramid gives the equation ___________.
C) Solving this equation shows that s = __________
Answer:
[tex](a)s^2\\(b)162=2s^2\\(c)s=9$ ft[/tex]
Step-by-step explanation:
(a)Base Area
Side length of square base=s
Area of a Square of side length s=[tex]s^2$ ft^2[/tex]
(b)
Height =6 ftVolume=[tex]162 $ ft^3.[/tex]Volume of a Pyramid[tex]=\frac{1}{3}X$Base Area X Height[/tex]
Substituting the given values, we have:
[tex]162=\frac{1}{3}Xs^2 X 6\\\\162=2s^2[/tex]
(c)Solving the equation derived from (b)
[tex]162=2s^2\\$Divide both sides by 2\\s^2=81\\s^2=9^2\\s=9$ ft[/tex]
Solving this equation shows that s =9 ft.

A long year-end status report for work is 144 pages long. You need to print 16 copies for a meeting next week. How much is the paper going to cost for those reports? Paper is sold in reams (500 pages) for $3.54 each.
Give your answer to the nearest cent, only for the paper you use (partial reams are OK)
Submit Question
Answer: The paper going to cost $16.31 for those reports.
Step-by-step explanation:
Given, the length of a long year-end status report for work = 144
If we ned to print 16 copies for a meeting next week, the total number of pages required = 16 *144
= 2304
Since, the paper is sold in reams of 500 pages = $3.54
Then, cost of one page = (Cost of a ream of 500 pages) ÷ 500
= $3.54 ÷ 500
= $ 0.00708
Cost of total number of pages required = 2304x (cost of one page)
= 2304 x ($ 0.00708)
= $ 16.31232 ≈ $16.31
Hence, the paper going to cost $16.31 for those reports.
