Answer:
4/10 or 2/5 of a mile more.
Step-by-step explanation:
Since the denominators are the same, all you have to do is subtract the numerators.
9-5=10.
Therefore, Alisha hiked 2/5 of a mile further than Joseph.
Answer:
Step-by-step explanation:
let pickle bought by alexa =x
then according to given condition ,
pickle bought by Tom= (1/3) of Alexa
pickle bought by Tom= (1/3) x
hence also given
totall pickle cost = Tom cost + alexa cost = 56p
(1/3)x+x=56
taking L.C.M
(4/3)x=56
x=56*3/4
x=42 p
so it means,
<h2>
Alexa cost = x = 42p</h2><h2>
Tom cost = (1/3)x= (1/3)*42 = 14 p</h2>
Answer:
The surface of the prism is 84m²
Step-by-step explanation:
You have 4 figures here (two the same triangles)
you need to determine the surface of each and then sum it to one. This will be your final surface.
rectangles:
3*6= 18m²
5*6 = 30m²
4*6 = 24m²
triangles:
You need to determine the square of the triangles from the Heron's formula.
Heron's formula states that the area of a triangle whose sides have lengths a, b, and c is
,
where s is the semi-perimeter of the triangle; that is,
.
So the permimeter of the triangle is
2p=4+5+3 = 12m
p = 6m
So the surface of the prism is a total sum of all surfaces:
P = 18m²+30m²+ 24m²+2*6m² = 84m²
