Charles drove three times as far as Emily. Altogether they drove 112 miles. What was the number of miles driven by Charles?
Answer: Charles drove 84 miles
Step-by-step explanation:
(c)harles = 3 x (e)mily
e + c = 112
Since Charles is 3x Emily, we can plug in 3e instead of c
e + 3e = 112
4e = 112
e = 112/4
e = 28
Emily drove 28 miles, and Charles drove 3x that, so Charles drove
28 x 3 = 84

Answer:
1/5 = 3/15
2/3 = 10/15
When all Added up
= 13/15
Step-by-step explanation:
So our LCD here is 15.
So in order to go from 5 to 15, we multiply by 3, and In order to go from 3 to 15, we multiply by 5. What we do to the denominator we also do to the numerator.
So,
[tex]\frac{1}{5} x \frac{3}{3} = \frac{3}{15}[/tex]
And,
[tex]\frac{2}{3} x \frac{5}{5} = \frac{10}{15}[/tex]
So there you go, multiply for what you need to get to the LCD, and what is done to the numerator is also done to the denominator. Enjoy

The length of a rectangle is 12 inches more than its width. The perimeter is 280 inches. Find the length and the width of the rectangle.
Answer:
width = 64 inches
lenght = 76 inches
Step-by-step explanation:
2(x + 12) + 2x = 280
2x + 24 + 2x = 280
4x = 280 - 24
4x = 256
x = 256/4
x = 64

Step-by-step explanation:
Suppose you invest in a fund which
.
• compounds at a rate of 1% at the end of every odd-numbered month (January, March, May, July.
September, November), and
.
• compounds at a rate of 3% at the end of every even-numbered month (February, April, June, August.
October, December).
How much do you need to invest on January 1st so that you have $1000 by June 1st of the same year?
The amount to invest on January 1st so that you have $1000 by June 1st of the same year is $992.54
What is monthly compounding?
Monthly compounding means that the interest is computed every month, in essence, the interest in January, March and May would be 1% divided by 12 months in a year whereas the interest in February, April, would be 3% divided 12 months making a year.
FV=PV*(1+r1)*(1+r2)*(1+r3)+(1+r4)*(1+r5)
FV=the future value June 1st of the same year=$1000
PV=the amount that needs to be invested=unknown
r1=January interest rate=1%/12=0.00083333333333
r2=February interest rate=3%/12=0.0025
$1000=PV*(1+0.00083333333333

if x,4x+3 and 7x+3 are geometric sequence. find the value of x
please help me
Answer:
x = [tex]\frac{-6}{7+\sqrt{13}}[/tex]
r = [tex]\frac{1+\sqrt{13} }{2}[/tex]
Step-by-step explanation:
In mathematics, a geometric progression, also known as a geometric sequence, is a sequence of numbers where each term after the first is found by multiplying the previous one by a fixed, non-one number called the common ratio.
For example, the sequence 2, 6, 18, 54, ... is a geometric progression with common ratio 3. Similarly 10, 5, 2.5, 1.25, ... is a geometric sequence with common ratio 1/2.
-----
Let's take r=ratio of the geometric sequence
in first term, x is multiplied by [tex]r^{0}[/tex]
First term: x [tex]r^{0}[/tex]
Second term: 4x+3 = x [tex]r^{1}[/tex]
Third term: 7x+3 = x [tex]r^{2}[/tex]
From the last 2 equation, we have to obtain r and x values.
Second equation - First equation:
3x = x r (r - 1)
Let's state: x different from 0, so we can simplify x, obtaining:
3 = [tex]r^{2}[/tex] - r
0 = [tex]r^{2}[/tex] - r - 3
r = [tex]\frac{1+\sqrt{13} }{2}[/tex] (only the positive value of r counts)
so, going to second term of the sequence:
4x+3 = x [tex]r^{1}[/tex] => x (4 - [tex]\frac{1+\sqrt{13} }{2}[/tex] ) = -3
x ([tex]\frac{7+\sqrt{13} }{2}[/tex] ) = -3 => x = [tex]\frac{-6}{7+\sqrt{13}}[/tex]

Equation of a straight line:
[tex]\displaystyle\\\frac{x-x_1}{x_2-x_1} =\frac{y-y_1}{y_2-y_1} \\\\x_1=0\ \ \ \ x_2=3\ \ \ \ y_1=-5\ \ \ \ y_2=3\\\\Hence,\\\\\frac{x-0}{3-0} =\frac{y-(-5)}{3-(-5)}\\\\\frac{x}{3} =\frac{y+5}{3+5} \\\\\frac{x}{3} =\frac{y+5}{8} \\[/tex]
Multiply both parts of the equation by 24:
[tex](8)(x)=(3)(y+5)\\8x=(3)(y)+(3)(5)\\8x=3y+15\\8x-15=3y+15-15\\8x-15=3y[/tex]
Divide both parts of the equation by 3:

Let y = f(x)

g(x) = (2x^2 + 3x - 4)
Use the chain rule.

There are four activities on the critical path. Coincidentally, their standard deviations are all equal to 4. The standard deviation of the critical path is therefore equal to:
Answer:
the standard deviation of the critical path is 8
Step-by-step explanation:
The computation of the standard deviation of the critical path is shown below:
As we know that
Variance = Standard deviation^2
Now the variance of the critical path is
= Variance 1 + variance 2 + variance 3 + variance 4
= 4^2 + 4^2 + 4^2 + 4^2
= 64
Now the standard deviation would be
= √64
= 8
hence, the standard deviation of the critical path is 8

The actual distance between Singapore and Jakarta is 1000 km. On a particular map. 1 cm on
the map represents 200 km on the ground. What length on the map represents the distance
between the two cities?
5 cm
10 cm
15 cm
Answer:
5cmStep-by-step explanation:
From the questions;
1cm represents 200km on the map
If the length of distance between the cities is 1000km, the distnce on the map will be say x;
x cm = 1000 km
Divide both equations;
1/x = 200/1000
Cross multiply;
200x = 1 * 1000
200x = 1000
x = 1000/2000
x = 5cm
Hence the length on the map that represents the distance between the two cities is 5cm
