$\qquad\qquad\huge\underline{{\sf Answer}}$

Linear equation has a degree of 1, that means the maximum power of a variable in a linear equation/expression should be 1. if an equation doesn't satisfy this condition then it's not a linear equation.

So, by Observing the choices, we get to the conclusion that the one which isn't a linear equation is B

$\qquad \sf \dashrightarrow \: {x}^{3} - 5 {y}^{2} = 4$

Here, the variables have greater powers tham one, and degree is 3. so it's the required Answer ~

Answer:

I think that B is not a linear equation.

Step-by-step explanation:

Linear eqautions can not contain exponents in them. B has x to the power of 3 and y to the power of 2, ruling it out to be a linear equation.
I hope this helps! :)

Please can you give me the answers to the questions above in standard form.

ivanzaharov [21]

Answer:

a) $4.5 \times 10^{11}$

b) $3.5 \times 10^{3}$

Step-by-step explanation:

a) We have to simplify the below expression in standard form.

The expression is $(5\times 10^{3}) \times (9 \times 10^{7})$

Now, $(5\times 10^{3}) \times (9 \times 10^{7})$

= $(9 \times 5) \times (10^{3} \times 10^{7})$

= $45 \times 10^{(3 + 7)}$ {Since $a^{b} \times a^{c} = a^{(b + c)}$ }

= $45 \times 10^{10}$

= $4.5 \times 10^{11}$ (Answer)

b) We have to simplify the below expression in standard form.

The expression is $(7\times 10^{5}) \div (2 \times 10^{2})$

Now, $(7\times 10^{5}) \div (2 \times 10^{2})$

= $(7 \div 2) \times (10^{5} \div 10^{2})$

= $3.5 \times 10^{(5 - 2)}$ {Since $a^{b}\div a^{c} = a^{(b - c)}$ }

= $3.5 \times 10^{3}$ (Answer)

Ursula and Velda live 4 km apart. They leave their homes at the same time, walking towards each other. If Ursula walks at a rate

vladimir2022 [97]

Answer: 250 m

Step-by-step explanation:

Given

Distance between Ursula and Velda house is 4 km or 4000 m

Ursula walks at the rate of $400\ m/h\ or\ \frac{20}{3}\ m/min$

Velda walks at the rate of $600\ m/h\ or\ 10\ m/min$

Time taken by them to cover 4000 m is

$\Rightarrow \dfrac{4000}{400+600}=4\ h\ or\ 240\ min$

Distance covered by them 15 min before they meet

Ursula $=\frac{20}{3}\times 225=1500\ m$

Velda $=10\times 225=2250\ m$

The total length covered by them is $=1500+2250=3750\ m$

They are $4000-3750=250\ m$ apart before they meet
