Andrei [34K]

Answer:

Amount of simple interest in three year = 750

Step-by-step explanation:

Given:

Amount invested = 5,000

Number of year = 3 year

Rate of interest = 5% Annually

Find:

Amount of simple interest in three year

Computation:

Simple interest = (P){R)(T)

Amount of simple interest in three year = (5,000)(3)(5%)

Amount of simple interest in three year = (5,000)(3)(0.05)

Amount of simple interest in three year = (5,000)(0.15)

Amount of simple interest in three year = 750

1/x + 1/a=1/b,then x=

motikmotik

$\dfrac{1}{x}+\dfrac{1}{a}=\dfrac{1}{b}\ \ \ |subtract\ \dfrac{1}{a}\ from\ both\ sides\\\\\dfrac{1}{x}=\dfrac{1}{b}-\dfrac{1}{a}\\\\\dfrac{1}{x}=\dfrac{a}{ab}-\dfrac{b}{ab}\\\\\dfrac{1}{x}=\dfrac{a-b}{ab}\Rightarrow\dfrac{x}{1}=\dfrac{ab}{a-b}\to\boxed{x=\dfrac{ab}{a-b}}$

What is the perimeter (please explain your answer)

Alex

Answer:

Answer: B. 38 mm

Step-by-step explanation:

The Perimeter of a Shape

The perimeter of a given shape is the sum of all exterior lengths surrounding the shape.

The figure shows a shape where all the external measures are given except the leftmost side.

This length is the sum of 3 mm + 10 mm = 13 mm.

Now calculate the perimeter:

P = 4 mm + 3 mm + 10 mm + 8 mm + 13 mm = 38 mm

Answer: B. 38 mm

A scientist found that x grams of Metal A is completely oxidized in 2x13 seconds and x grams of Metal B is completely oxidized i

ExtremeBDS [4]

Answer: Metal A is 3 times faster than Metal B.

Step-by-step explanation:

Since we have given that

Time taken to oxidised metal A = $2x\sqrt{3}\ seconds$

Time taken to oxidised metal B = $6x\sqrt{3}$ seconds

So, ratio of metal A to metal B would be

$\dfrac{Metal\ A}{Metal\ B}=\dfrac{2x\sqrt{3}}{6x\sqrt{3}}=\dfrac{1}{3}$

So, Ratio of Metal A to Metal B is 1 : 3.

Hence, Metal A is 3 times faster than Metal B.
