Am i doing this right????

Anna35 [415]

You are going in the right direction. For the distance of ST I get √136
√(-5-1)² + (6+4)² =
√(-6)² + (10²) =
√ 36 + 100 =
√136

√34² + √136² =√170²
34 + 136 = 170
170 = 170

First, combine like terms:

(6.7+4.3= 11)

-11.6>11+m
isolate m on one side
-11.6-11>m
=
m<-22.4

describe how to find the price of a blender 3 years from now the inflation is constant at 4% and the the blender costs 38$ today

Ludmilka [50]

FV = PV / (1 +r)^n

Where FV = Future Value, PV = Present Value, r = inflation rate in %,
n = number of years.

PV = $38, r = 4%, n = 3 years.

FV =    38 / (1 + 4%)^3

= 38 / (1 + 0.04)^3

= 38 / (1.04)^3 =    33.782

Hence the value 3 years from now = $33.78

In 1975 1000 tons of coal was manufactured. It is 10% greater in 1976 and 5% less in 77. What is the final about of coal in 1977

Digiron [165]

In 1975 it was 1000tons, ok, well, in 1976 it went up by 10%, how much is a 10% increase?

$\bf \begin{array}{ccllll}
coal&\%\\
\text{\textemdash\textemdash\textemdash}&\text{\textemdash\textemdash\textemdash}\\
1000&100\\
x&100+10
\end{array}\implies \cfrac{1000}{x}=\cfrac{100}{100+10}\implies \cfrac{1000\cdot 110}{100}=x
\\\\\\
1100=x$

well, in 1976 it was 1100 tons then, and in 1977 it went down by 5% of 1100, well, if we take 1100 to be the 100%, then what is a 5% decrease?

$\bf \begin{array}{ccllll}
coal&\%\\
\text{\textemdash\textemdash\textemdash}&\text{\textemdash\textemdash\textemdash}\\
1100&100\\
x&100-5
\end{array}\implies \cfrac{1100}{x}=\cfrac{100}{100-5}\implies \cfrac{1100\cdot 95}{100}=x$
