An ant weighs 2 x 10^-3 grams, and a lion weighs 1 x 10^5. The lion's weight is 5 x 10^x times greater than the ant's weight. Wh

julsineya [31]

Answer:

x=7

Step-by-step explanation:

Information provided

Weight of ant= $2*10^{-3} grams$

Weight of lion= $1*10^{5}$ but units are not provided, assuming this unit is also grams

How many times lion's weight exceed an ant

$\frac {1*10^{5}}{2*10^{-3}}=50000000$

= $5*10^{7}$

Therefore, the value of x=7 if the unit for weight of lion is assumed to be same as unit for weight of an ant

love history [14]

Answer:

$\approx$ 17.5% per annum

Step-by-step explanation:

Given:

Money invested = $20,000 at the age of 20 years.

Money expected to be $500,000 at the age of 40.

Time = 40 - 20 = 20 years

Interest is compounded annually.

To find:

Rate of growth = ?

Solution:

First of all, let us have a look at the formula for compound interest.

$A = P \times (1+\frac{R}{100})^T$

Where A is the amount after T years compounding at a rate of R% per annum. P is the principal amount.

Here, We are given:

P = $20,000

A = $500,000

T = 20 years

R = ?

Putting all the values in the formula:

$500000 = 20000 \times (1+\frac{R}{100})^{20}\\\Rightarrow \dfrac{500000}{20000} =(1+\frac{R}{100})^{20}\\\Rightarrow 25 =(1+\frac{R}{100})^{20}\\\Rightarrow \sqrt[20]{25} =1+\frac{R}{100}\\\Rightarrow 1.175 = 1+0.01R\\\Rightarrow R \approx17.5\%$

So, the correct answer is $\approx$ 17.5% per annum and compounding annually.

Pentagon VWXYZ is shown on the coordinate grid. A student reflected pentagon VWXYZ across the x-axis to create pentagon V’W’X’Y’

pav-90 [236]

Reflecting across the x axis maintains the same x coordinate, but changes the sign of the y coordinate.

So, the transformation is

$(x,y)\mapsto (x,-y)$
