Charles drove three times as far as Emily. Altogether they drove 112 miles. What was the number of miles driven by Charles?

Answers

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

Charles drove 84 miles.

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

Step-by-step explanation:

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.

Answers

use the equation p=2l+2w and sub everything in to get 280=2l+2(l+12).
distribute the 2 for 280=2l+2l+24.
add/subtract like terms over, leaving you with 256=4l.
divide the 4 from 256, resulting in l=64.
since w=l+12, add 12 to 64 to find that w=76.
basically, l=64 and w=76.
hope this helps!

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

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?

Answers

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​

Answers

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]

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:

Answers

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

Answers

Answer:

5cm

Step-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
