The area and length of a rectangle are given below. Find the w, the width.
Answer:
1.5
Step-by-step explanation:
yaaa
This is the same as 1.5 feet and it is equivalent to the improper fraction 3/2.
============================================================
Explanation:
Let's convert the given mixed numbers into improper fractions.
A = 5 & 1/3 = 5 + 1/3 = 15/3 + 1/3 = (15+1)/3 = 16/3
L = 3 & 5/9 = 3 + 5/9 = 27/9 + 5/9 = (27+5)/9 = 32/9
So the area and length are 16/3 and 32/9 respectively.
-------------------
Let's solve for the width W
area = length*width
A = L*W
16/3 = (32/9)*W
9*(16/3) = 9*(32/9)*W ..... multiplying both sides by 9
48 = 32W
32W = 48
32W/32 = 48/32 ....... dividing both sides by 32
W = 48/32
W = (32+16)/32
W = 32/32 + 16/32
W = 1 + 1/2
W = 1 & 1/2 feet is the width
This is equivalent to 3/2 since 48/32 = 3/2
It's also equivalent to 1.5 because 3/2 = 1.5

Hi! Your answer is x = 3.
Please see an explanation for a clear and better understanding to your problem.
Any questions about my answer and explanation can be asked through comments! :)
Step-by-step explanation:
Our goal is to find the value of x. That means what we have to do is to isolate x-term first.
[tex]\huge{x+10=13}[/tex]
To isolate a variable means that to make a variable as a subject or also known as leaving a variable alone. To isolate the x-term for this problem, simply subtract both sides by 10 so we can get rid of 10 from the left side.
[tex]\huge{x+10-10=13-10}\\\huge{x+0=3}\\\huge{x=3}[/tex]
If you are not sure that the answer is correct or not. We can substitute the value of x in the equation.
[tex]\huge{x+10=13}[/tex]
Substitute x = 3 in the equation.
[tex]\huge{3+10=13}\\\huge{13=13}[/tex]
The equation is true for x = 3. Hence, we can conclude that x = 3 is the solution to the equation.
An artist builds a sculpture out of metal and wood that weighs 14.4 kilograms. 3/4 of this weight is metal, and the rest is wood. How much does the wood part of the sculpture weigh?
Answer: weight of wood part = 3.6 kilogram.
Step-by-step explanation:
Sculpture made of both metal and wood = 14.4 kilogram
Weight of metal=3/4 of 14.4 kilogram
which means the weight of metal = 3/4 x 14.4kg= 10.8kg
Since the rest is wood, we can say that
weight of wood = Total weight - weight of metal
= 14.4 kilogram- 10.8 kilogram= 3.6 kilogram

What is the product of (x+3)(x-3)=7
Answer:
Step-by-step explanation:
What you have here is an equation with two roots. The "product" is (x + 3)(x - 3), which comes out to x^2 - 9.
Thus, you have x^2 - 9 = 7, or x^2 - 16 = 0, and the roots of that are {-4, 4}.

220 is divided in the ratio 3:8 as 60 and 160 respectively.
What is the ratio?The ratio is defined as the comparison of two quantities of the same units that indicates how much of one quantity is present in the other quantity.
The given ratio is 3:8 and the number is 220.
Here, 3+8=11
Now, 3/11 ×220
= 3×20
= 60
8/11 ×220
= 8×20
= 160
Therefore, 220 is divided in the ratio 3:8 as 60 and 160 respectively.

Read the excerpt from "The Tell-Tale Heart."
Which statement best explains how the reader can
determine that the narrator is unreliable?
But you should have seen me. You should have seen
how wisely I proceeded—with what caution—with what
foresight—with what dissimulation I went to work! I was
never kinder to the old man than during the whole week
before I killed him. And every night, about midnight, I
turned the latch of his door and opened it-oh so
gently! And then, when I had made an opening
sufficient for my head, I put in a dark lantern, all closed,
closed, that no light shone out, and then I thrust in my
head. Oh, you would have laughed to see how
cunningly I thrust it in!
O The narrator is very kind to the old man during the
whole week before the murder.
O The narrator checks on the old man every night at
midnight to ensure his well-being.
O The narrator closes the lantern tightly so the old
man is not awakened by the bright light.
O The narrator believes that his audience will approve
of and even laugh at his plot to murder the old man.
Answer:
The narrator checks the old man at every night at midnight
