never
Step-by-step explanation:
Step-by-step explanation:
this creates 2 similar triangles.
that means all angles are the same. and all the side lengths of one triangle correlate to the corresponding side lengths of the other triangle by the same multiplication factor.
her shadow is 23.05 - 18.9 = 4.15 m long.
the factor between the shadow lengths is then
4.15 × f = 23.05
f = 23.05 / 4.15 = 5.554216867...
the same factor now applies to the relation of the heights :
1.45 × 5.554216867... = 8.053614458... m
rounded the tree is 8.05 m tall.
Step-by-step explanation:
oh, come on, just multiplication.
7.5×10⁴ years is 7.5×10000 =75000 years.
0.005 inches per year for 75000 years means
0.005 × 75000 = 5 × 75 = 375 inches.
I’m pretty sure the answer is -1
Answer:
Step-by-step explanation:
to turn a decimal to a percent, multiply by 100.....or if there is a decimal in there, start from the decimal and just move 2 spaces to the right.
2.346 = 234.6%
and just so you know, to turn a percent to a decimal, divide by 100...or move the decimal point 2 spaces to the left
