51 should be the correct answer
Answer:
Amount he must save to earn his goal = $7193.1≅
Step-by-step explanation:
The 5.5% interest is compounded quarterly, hence the compound interest expression is used
A = P(1+r%)ⁿ
A = $26000
P = ?
r = 5.5%
n = 4 x 6 = 24 quarters
P = A ÷ (1+r%)ⁿ = 26000 ÷ (1 + 0.055)²⁴ = 7193.070497956 = $7193.1≅

Answer:
The correct expression for the perimeter is
see the explanation
Step-by-step explanation:
The complete question in the attached figure
Let
L ----> the length of rectangle
W ---> the width of rectangle
we know that
The perimeter of rectangle is equal to
In this problem we have
substitute the values
Simplify
so
Michelle didn't multiply the sum of length and width by 2
Answer:
D
Step-by-step explanation:
Imagine this as a right angle triangle, where the diagonal length is the hypotenuse, the length is one side, and the width is the other.
We can therefore use Pythagoras' Theorem (or Pythagorean Theorem) to solve. The formula for this is a²+b²=c², where c is the hypotenuse, and a and b are the sides.
We can input the values we know to this formula to get the width. This gives 110²+b²=133.14² or 12100+b²=17 726.2596.
From there subtracting 12100 from both sides gives b²=5626.2596.
Square rooting b isolates it, leaving b=75.0083969.
Since the value of the diagonal was approximate, this can be assumed the b is 75m.
