The perimeter of a rectangular tray is 28 inches. The length of the tray is 2 inches longer the width of the tray. Determine the dimensions of the rectangular tray.
Answer:
width = 6 and length = 8
Step-by-step explanation:
perimeter = 2*(length + width). (1)
and we have that length = 2 + width
in (1)
28 = 2 *(width + 2 + width)
14= 2*width +2
width =6
and so length will be 8

Help I need to know if each statement is always, sometimes, or never true
please help find the sum of all even integers from 2 to 100
Answer:
2550
Step-by-step explanation:
2 + 4 + 6 + ……… + 98 + 100
= (2×1) +(2×2) + (2×3) + ……… + (2×50)
= 2 × (1 + 2 + 3 + ………. + 50)
The sum (S) of n natural numbers is given by -
S = (n × (n + 1) )/2
Therefore,
2 × (1 + 2 + 3 + ……… + 50)
= 2 × ((50 × 51)/2)
= 2 × (2550/2)
= 2 × 1275
= 2550

So we can't divide fractions but what we can do is multiply them.
The First step is to do KCF (Keep, Change, Flip)
So It will be 2/7 TIMES 4/3. Keep 2/7 change the division sign to multiplication sign and flip 3/4 to 4/3. Now Multiply normally.

A woodpecker pecked at a 17 m wooden pole until it cracked and the upper part fell with the top hitting the ground 10 m from the foot of the pole. Since the upper part had not completely broken off, the bird pecked away where the pole had cracked. How far was the bird above the ground?
Answer:
the woodpecker was 7m above the ground
The height where the bird pecked is 7m above the ground.
What is a numerical expression?A numerical expression is a mathematical statement written in the form of numbers and unknown variables. We can form numerical expressions from statements.
Given, A woodpecker pecked at a 17 m wooden pole until it cracked and the upper part fell with the top hitting the ground 10 m from the foot of the pole.
Therefore, If the length of the pole that fell down is 10m then the length of the remaining pole is,
= (17 - 10)m.
= 7m.
So, The bird pecked away where the pole had cracked is 7m.
