Answer:
38cm taller
Step-by-step explanation:
jack is 178cm tall
the ladder is 280cm tall
jack standing on the ladder is 280cm taller
so 178+280=458
the tree is 420cm tall
458>420
which means that jack is now taller than the tree standing in the ladder
458-420=38
so jack is 38cm taller than the tree standing on the top of the ladder
Answer:
0.60, 2/3, 70%, 3/4, .85
Step-by-step explanation:
Answer:
84
Step-by-step explanation:
Since we are given line OP perpendicular to line DR, then angles PDR and ODR are right angles.
Angles PDA and ADR are complementary.
Angles ODU and UDR are complementary.
Angles ADR and UDR are given as congruent.
We can conclude that angles PDA and ODU are congruent.
By AA Similarity, triangles APD and UMD are similar.
DP/DM = PA/MU
3.75/10 = 4.5/MU
3.75MU = 10 × 4.5
MU = 12 (altitude of triangle DUO)
OD = OM + MD = 4 + 10 = 14 (base of triangle DUO)
area = base × height / 2
area = 14 × 12 / 2
area = 84
Answer:
0.23
Step-by-step explanation:
Using either long division or a calculator, divide 23 by 100; you will get the result 0.23.
