1 answer:

6 0

Let June's age be
$x \: years$

Then his father is
$6x \: years$

The sum of their ages is no less than 77 means,
$x + 6x \geqslant 77$
$7x \geqslant 77$
$x \geqslant 11$
The youngest age June can be is 11

Someone please help me w this standard form question

Answer:

2.4 × 10⁶

Step-by-step explanation:

Given:

$\sf x=3.8 \times 10^5$

$\sf y=5.9 \times 10^4$

To calculate the value of R, substitute the given values into the given formula:

$\begin{aligned}\sf R & = \sf \dfrac{x^2}{y}\\\\ \implies \sf R& = \sf \dfrac{(3.8 \times 10^5)^2}{5.9 \times 10^4}\\\\& = \sf \dfrac{3.8^2 \times (10^5)^2}{5.9 \times 10^4}\\\\& = \sf \dfrac{14.44 \times 10^{10}}{5.9 \times 10^4}\\\\& = \sf \dfrac{14.44}{5.9} \times \dfrac{10^{10}}{10^4}\\\\& = \sf 2.4474... \times 10^{(10-4)}\\\\& = \sf 2.4474... \times 10^6\\\\\end{aligned}$
