2.4m log is cut into lengths into the ratio 7 : 5. Find the longer length in cm.

sergeinik [125]

Answer:

140 centimeters.

Step-by-step explanation:

Hello!

A 2.4 meter log is split into the ratio 7:5. Each unit part is one x-increment, so the log is split into 7 x-increments and 5 x-increments.

Find the longer length:

2.4 into 7:5
2.4 = 7x + 5x
2.4 = 12x
x = 2.4/12
x = 0.2

Now, we must find the longer length, 7x.

7x
7(0.2)
1.4

The longer length is 1.4 meters, but we want it in cm.

There are 100 centimeters in a meter.

1.4 meters = 1.4 * 100
1.4 meters = 140 centimeters

The longer length is 140 centimeters.

The formula A equals =P left parenthesis 1 plus r right parenthesis squared (1+r)2 gives the amount A in dollars that P dollars

vlabodo [156]

The interest rate is 3.5%.

EXPLANATION

We substitute the given values into the formula;

$A=P(1+\frac{r}{100})^t$

to obtain

$6427.35=6000(1+\frac{r}{100})^2$

We divide through by 6000 to obtain,

$\frac{6427.35}{6000}=(1+\frac{r}{100})^2$

This implies that,

$1.071225=(1+\frac{r}{100})^2$

We take the square root of both sides,

$\sqrt{1.071225}=(1+\frac{r}{100})$

This gives us,

$1.035=(1+\frac{r}{100})$

Add -1 to both sides of the equation to obtain

$0.035=\frac{r}{100}$

Multiply through by 100 to obtain;

$r=3.5$ %

$Therefore the rate is 3.5%$
