Answer:Joan's height is 127 centimetres
Step-by-step explanation:
Step 1
Joan is 4 feet 2 inches tall and we want to change to centimeters .
we first change her height to inches
1 Foot = 12 Inches
Therefore 4 Feet = 4 x 12 = 48 inches
Total height in inches =48 inches + 2 Inches = 50 inches
Step 2 --Now, we have gotten her height in inches, we can now change to centimetres.
We have that
1 inch =2.54 centimeters
50inches = 50 x 2.54 cm
=127 centmeters.
Joan's height is 127 centimetres
Answer:x=9
Step-by-step explanation:
To find the positive solution for this, then we will say;
Let the number be x
3x<x^2-54
x^2-3x-54<0
Then we are going to factorise
x^2-9x+6x-54=0
(x^2-9x)+(6x-54)=0
x(x-9)+6(x-9)=0
(x+6)(x-9)=0
Therefore, The positive solution for this is: x=9
The space between the end of the wall and the towel rack will be <u>9.2 inches</u>.
<h3>What is space?</h3>
Space is the relative position of objects at a distance from one another.
In this instance, space refers to the empty area at each end of the towel rack.
<h3>Data and Calculations:</h3>
The length of the towel rack = 58.4 inches
The length of the wall = 76.8 inches
The difference between the lengths of rack and wall = 18.4 inches (76.8 - 58.4)
Since Henry wants the towel rack to be centered, the space between the end of the wall and the towel rack will be <u>9.2 inches</u> (18.4/2).
Thus, the space between the end of the wall and the towel rack will be <u>9.2 inches</u>.

Answer:
65
Step-by-step explanation:
(4-7i)(4+7i) =16 + 28i-28i -49i^2 ➡16 - 49i^2
16 + 49 = 65
the fault here is i^2= -1 and -1 multiplied by -49 is +49 not -49
Answer:
<em>780cm cubed</em>
Step-by-step explanation:
- <em>if we want to find the volume we would do length x width x height</em>
- <em>which would be 5 x 12 x 13</em>
- <em>so we would do 5 x 12 which is 60 </em>
- <em>then we would do 60 x 13 which equals 780</em>
- <em>So the answer is 780</em>
- <em>Since this is volume it would be 780cm cubed</em>
