The human body is made up of about 9.3% hydrogen. What is the amount of hydrogen contained in a person who weighs 140 pounds? Round you answer to the hundredths place
Answer:
We know that for a human body 9.3% of its total mass is hydrogen.
Now we have a person with a mass of 140 lb.
Then we have that the 100% of the mass is 140lb, the 9.3% of this is hydrogen.
We can write:
9.3% = X
100% = 140lb
We want to find the value of X (mass of hydrogen)
Then we can take the quotient of these two equations to get:
(9.3%/100%) = X/140lb
Now we can isolate the variable X to get:
(9.3%/100%)*140lb = X = 13.02 lb
So this person has about 13.02 lb of hydrogen in his/hers body.
In the figure above, if l ll m and r ll s, what is the value of x?
A) 65
B) 80
C) 85
D) 95
E) 115
Check the photo and please show the steps
Answer:
C x= 85°
Step-by-step explanation:
x+ 60° + 35° =180°
x= 180° - 60° - 35°
x= 85°

Ashley is buying items for her dog Lance. She buys a dog collar for $6.50 and wants to buy dog food at $4 a pound. If she wants to spend exactly $22.50, how many pounds of dog food can she afford? Which equation model this situation? *
1 point
4lbs : 6.50x + 22.50 = 4
5lbs : 4x + 6.50 = 22.50
4lbs : 4x + 6.50 = 22.50
4lbs : 4 + 6.50x = 22.50
Answer:
4 lbs : 4x + 6.50 = 22.50
Subtract 6.50 from 22.50 and divide the remaining number by 4.
A retiree invests $7,000 in a savings plan that pays 7% per year. What will the account balance be at
the end of the first year?
Answer:
$6510
Step-by-step explanation:
First thing that should come to mind is: What is 7% of $7000?
Well, if you don't know how to find a percent of something, this is the formula you use:
7000 x 0.07 = 490.
In the first year, they will receive 490 out of the 7000 they've invested.
7000 - 490 = 6510.
Therefore, the account balance at the end of the first year will be 6510.
The account balance at the end of first year will be equal to $6510.
What do you mean by percentage ?
Percentage is the relative value indicating one hundredth part of any quantity.
It is given that a retiree invests $7000 in a savings plan which pays 7% per year. So , it meant that we need to calculate that what is the value 7% of $7000.
So , 7% of $7000 is :
= 7000 × [tex]\frac{7}{100}[/tex]
= $490
It is known that this amount is paid as per plan per year. So, to find out the account balance at the end of the first year , we need to subtract the invested amount to the amount per year at 7%.
So , the account balance at the end of first year will be :
= 7000 - 490
= $6510
Therefore , the account balance at the end of first year will be equal to $6510.

GUYS HELP!! What’s an equation that represents the line on the graph?
Answer:
Hey Mate...
Step-by-step explanation:
All that the slope-intercept form (the equation to describe linear equations) is, is an equation (y=mx+b) where m (the number that multiples x) is the slope and b (the number that is not multiplying a variable on the right-hand side of the equation) is the y-intercept.

What is the box and whisker plot?A box and whisker plot is a method of abstracting a set of data that is approximated using an interval scale. It's also known as a box plot. These are primarily used to interpret data.
We have box plot data:
1,000 1,400 1,800 2,200 2,600 3,000
From the box plot:
The shortest distance Estelle swam at practice is given by:
= 1800—(1400+1800)/2
= 1800 – 1600
= 200 meter
Thus, the shortest distance Estelle swam at practice is 200 meters if the Estelle swims for the Shorewood Sharks swim team

PLS HELP !!!
Fiona spent 50 minutes to complete her homework. She spent 30 minutes on her
math assignment and 20 minutes on her science assignment. What fraction of time
did Fiona spend on her math assignment??
Answer:
3/5 of her time
Step-by-step explanation:
She spent 30 minutes out of 50 minutes on her math assignment. So, we can write this fraction:
30 minutes / 50 minutes
Divide both the numerator (top of the fraction) and denominator (bottom of the fraction) by 10 minutes to get
3 / 5
So, the answer is 3/5 of her time.
7 cameras cost $308. The cost of each camera is the same. What is the cost of each camera?
Answer:
$44
Step-by-step explanation:
Hello!
It said that 7 cameras cost $308, right?
If each camera costs the same, it means that 7 cameras with the same value equal $308.
If we use this in an equation, and if x is a variable we want to solve, it would be:
7x = 308.
If 7x = 308, it would be
308/7 =
44.
So, $44 is the answer.

Answer:
(b) y = (x +4)² -1
Step-by-step explanation:
The vertex form of the equation of a parabola is ...
y = a(x -h)² +k . . . . . . . . . vertex (h, k); scale factor 'a'
The graph shows the vertex is (h, k) = (-4, -1) and a=1. Putting these values into the form, we have ...
y =(x +4)² -1

A box is being packed with cubes that measure 1 cubic foot. What is the volume of the box in cubic feet
Answer:
81 cubic foot
Step-by-step explanation:
It is given that the box is packed with cubes whose side is 1 foot. So the volume of one cube is 1 cubic foot.
Now from the figure, we can see that :
Number of cubes fitting the box across its length = 9 cubes
Number of cubes fitting the box across its width = 3 cubes
Number of cubes fitting the box across its height = 3 cubes
And each of these cubes measures 1 x 1 x 1 cubic foot
So the volume of the box can be found out by:
Volume = length x width x height
= 9 x 3 x 3
= 81 cubic foot
Therefore volume of the box is 81 cubic foot.
