to do it in mental math: you can ignore the zeroes in 400 for now.
4*14 = 4*10 + 4*4 = 40 + 16 = 56
now add the zeroes back on: 5600m
Answer: A
Step-by-step explanation:
The maximum amount of weight the truck can carry is 1600lbs. You do not want to exceed 1600lbs, but you can reach 1600lbs. This makes the inequality symbol ≤. This symbol says that the weight load has to be less than 1600lbs, but It can equal 1600lbs. You know that the piano is 400lbs and each box is 50lbs. Since you want to figure out how many boxes you can put on the truck alongside the piano, you can use the inequality: 50x + 400 ≤ 1600.
50 represents pounds per/box
x represents the number of boxes you can hold
400 represents the weight of the piano
1600 represents the max weight.
Answer:
The coordinates of B' are (-3, 5).
Step-by-step explanation:
For every 90 degrees rotated, the coordinate numbers switch and one is multiplied by -1, when clockwise it's the 2nd one, and when counterclockwise, it's the 1st.
Answer:
whatpower7(49) = 2
Step-by-step explanation:
given data
WhatPower7(49)
to find out
Evaluate the expressions WhatPower7(49)
solution
as we know that whatpower mean exponent of equation so we get by given equation
we know whatpower7(49) = 2
because
we know that 7 × 7 = 49
so that 7² = 49
so that the exponent is here 2 for 7 that become 49
so correct answer is 2
Answer:
Adjacent length = √(50) m
Pythagorean theorem:
a^2 + b^2 = c^2
a = √(50) m
b = √(50) m
c^2 = √(50)^2 + √(50)^2
c^2 = 50 + 50
c^2 = 100
c = 10 m
Diagonal = 10 m
