I couldn't solve it because I would have to assume that the triangle is an equilateral triangle and all quadrilaterals are squares. He didn't make that specific so there is nothing I can do.
exactly the reason why I didn't bother myself too.
EducationRe: Does That Prefare Ice Cream To Maths, Maths is asking You Something (mr Shape) by dejt4u(m):
ifada123:
Find the height of the ice cream left in the conical container
If the volume is half the volume of the container
answer is 12.7cm

using the formula V =⅓×πr²h to find the height of the conical container, h = 16cm

now; for volume similar shapes, (V1/V2) = (h1/h2)³,
V1 = volume of the container,
V2 = volume of the ice cream,
h1 = height of the container, and
h2 = height of the ice cream

but (V1/V2) = 2 (since the volume of ice cream is half the volume of the container)

therefore, (h1/h2)³ = 2,
remember, h1 = 16cm

then, h2 = 12.7cm

I can't solve anything again today..

for this one; this is volume of similar shapes..

first calculate the height and volume of the conical container.. then half of the volume of the container is the volume of the ice cream left..

we use those three parameters to determine the height of the ice cream. thank you and good night

Thanks. It was a typo.
yes.. well done
EducationRe: I Know You Will Avoid It, But Solve. by dejt4u(m): 7:38pm On Apr 09, 2019
Martinez39:
Taking the common logarithms of both sides :
log xlog x = log (10⁴ × x³)
Using the properties of logarithms
(log x)(log x) = log 10⁴ + log x³
(log x)² = 4 + 3log x³ ----- an equation quadratic in form
If u = log x then u² = 4 + 3u
Using the quadratic formula to solve u² - 3u - 4 = 0
u = log x = 4 or u = log x = -1
ie. x = 10⁴ or x = 10-1

On checking, the solution set is, {10⁴, 10-1}
You made a mistake here. it didn't affect your workings though. a typographical error I think
(log x)² = 4 + 3log x³

It should be (log x)² = 4 + 3log x

You did well. keep it up
