The answer to #1 is the first/tallest blue bar. The way that it compares to a bacteria cell is that they both have the same water percentage.
Proteins make up a larger amount of an animal cell. I know this because the blue bar (representing the animal cell) is taller under the section of proteins than it is under nucleic acids.
I can tell that the chemical composition of bacterial and animal cells have a lot in common. All of the purple and blue bars match up almost perfectly, meaning that their compositions are almost the same.
Hope I helped, and I'd love to get brainliest :)

how would you write 77.7ovdrbar% as a decimal? Set that decimal equal to x. What digit or digits repeat
Answer:
[tex]0.777=0.\overline{7}[/tex]
Step-by-step explanation:
We are asked to write 77.7% as a decimal.
We know that percent means per hundred.
To write 77.7% as decimal, we will divide 77.7 by 100 as:
[tex]77.7\%=\frac{77.7}{100}[/tex]
Move decimal to left by two digits.
[tex]77.7\%=\frac{77.7}{100}=0.777[/tex]
Let us set 0.777 equal to x as:
[tex]x=0.777[/tex]
We can see that our decimal has three 7 digits after decimal, therefore, 1 digit is repeating after decimal.

You can peel 4 potatoes in 10 minutes. How long will it take you to peel 14 potatoes?
It would take you 35 minutes.
Since it takes 10 minutes to peel 4 potatoes, you can assume it would take 30 minutes to peel 12 potatoes (mulitiplying both numbers by 3). Then you'd add 5, instead of 10 because you are peeling 2 more potatoes than 12, instead of peeling 4, you'd divide 10 by 2 to get half the time it would take to peel half as many potatoes. Finally, add 30 and 5 to get you final answer of 35.
I hope this helps!
It will take 35 minutes to peel 14 potatoes, as it takes 2.5 minutes to peel one potato.
Since you can peel 4 potatoes in 10 minutes, this means that you can peel one potato in 10/4 minutes, or 2.5 minutes per potato. To peel 14 potatoes, we would multiply the time it takes to peel one potato by the number of potatoes: 2.5 minutes * 14.
2.5 minutes * 14 potatoes = 35 minutes
So, it will take you 35 minutes to peel 14 potatoes.

A)the eight term of arthematic sequence is 28, the common difference is 6 calculate the first term of sequence.
B) The sum of first n term is 760
calculate the vale of n.
Solution
Part A
The general form of the n-th term = a + (n-1)d
Here we are given the 8th term A8 = 28 , common difference (d) = 6
A8 = a + (n - 1) 6
28 = a + (8- 1)6
28 = a + 7*6
28 = a + 42
a = 28 - 42
a = -14
Part B
n-th term is 760. a = -14 and d = 6.
Plugging in the values in the general form, we get
760 = -14 + (n -1)6
760 = -14 + 6n - 6
760 = -20 + 6n
6n = 760 + 20
6n = 780
Dividing both sides by 6, we get
n = 780/6 = 130
The value of n is 130

Each brochure is 23 centimetres wide.
The table is 1.5 metres wide.
Estimate how many brochures you can put side by side on the table?.
Answer:
6 brochures
Step-by-step explanation:
Each brochures is 23 centimeters wide.
The table is 1.5 meters wide.
To know how many brochures can be placed side by side on the table first you have to calculate how many centimeters there are in 1.5 meters wide.
One meter equals 100 centimeters.
Therefore in 1.5 meters there are:
[tex]1.5*100 = 150[/tex] centimeters.
Now we must calculate in how many parts of 23 cm can be divided 150 cm.
To do this we made the division of 150 between 23
[tex]\frac{150}{23}= 6.522[/tex]
This means that up to 6 brochures of 23 cm can be placed side by side on the table

the complement of an angle is 25 degrees. what is the measure of the angle
complementary angles are angles whose measures equals 90° when added. so to find the measure of this angle, we subtract 25° from 90°. the measure of the angle is 65°.
65°
complementary angles have a sum of 90°
angle = 90° - 25° = 65°
Suppose there's 0.9811 ml of DEET in 1 ml of insect repellent. How much DEET would be in 20 ml of the repellent?
A. 19.622 ml
B. 24.5275 ml
C. 9.811 ml

Hence, the correct answer is (A).
Answer:
Answer: A. 19.622
Step-by-step explanation:
20x0.9811=19.622

HELP ASAP I WILL GIV YOU BRAINLIST! Jim ran 200 meters in 30.4 seconds. Mac ran 100 meters in 30.4 seconds. Who ran faster?
I'm thinking Jim ran faster. Sorry if I'm wrong
Hello, I'm Jenny and I'm happy to help you! :)
Lets set up an equation for this problem.
Jim: 200 meters | 30.4 seconds
Mac: 100 meters | 30.4 seconds
We both know that they ran different amount of meters in the same amount of seconds so whoever completed the furthest amount of meters ran the fastest.
Jim: 200, Mac: 100.
Since 200 is higher than 100, Jim ran the furthest amount of meters therefore,
Jim ran the fastest.

Suppose Jose buys 4 pounds of sausage that cost $8.79 per pound, a bottle of mustard that costs $1.38, and two loaves of Cuban bread that cost $3.99 each. How much did Jose spend in all?
Answer:
$44.52
Step-by-step explanation:
$8.79+$8.79+$8.79+$8.79=$35.16
$35.16+$1.38=$36.54
$36.54+$3.99+$3.99=$44.52
Or a simpler way to solve it would be
($8.79×4)+$1.38+($3.99×2)
Parentheses> Exponents >Multiplication> Division> Addition> Subtraction
Answer: Jose spent a total of $44.52.
Step-by-step explanation: Given that Jose buys 4 pounds of sausage that cost $8.79 per pound, a bottle of mustard that costs $1.38, and two loaves of Cuban bread that cost $3.99 each.
We are to find the total amount of money that Jose spent.
The amount of money spent on sausage is given by
[tex]A_s=4\times8.79=\$35.16,[/tex]
the amount of money spent on the bottle of mustard is
[tex]A_m=1\times1.38=\$1.38[/tex]
and the amount of money that spent on the loaves of Cuban bread is
[tex]A_c=2\times3.99=\$7.98.[/tex]
Therefore, the total amount of money spent by Jose is given by
[tex]A=A_s+A_m+A_c=35.16+1.38+7.98=\$44.52.[/tex]
Thus, Jose spent a total of $44.52.

Help!! What is the point in the feasible region maximizes the objection function?
First, find the vertices of the shaded region. You can do this my graphing or by solving a system of equations for each pair of functions. I am going to find them by graphing.
x ≥ 0 and y ≥ 0 place the shaded region in the first quadrant with a vertex at (0, 0)
now graph y ≤ 3. a vertex is at (0, 3)
now graph y < -2x + 5. a vertex is at (1, 3). the other vertex is the x-intercept (when y = 0).
0 = -2x + 5
-5 = -2x
[tex]\frac{5}{2} = x[/tex] So, the vertex is [tex](\frac{5}{2} , 0)[/tex]
Next, input the coordinates of the vertices into the objective function.
C = -6x + 5y
(0, 0): C = -6(0) + 5(0)
= 0 + 0
= 0
(0, 3): C = -6(0) + 5(3)
= 0 + 15
= 15
(1, 3): C = -6(1) + 5(3)
= -6 + 15
= 9
[tex](\frac{5}{2} , 0)[/tex]: C = -6(\frac{5}{2}[/tex]) + 5(2)
= -15 + 10
= -5
The maximum is C = 15 which occurs at vertex (0, 3)

Yes, they are both functions.
they are both functions.. when i was taking algebra my teacher taught me the straight edge trick.. you take a ruler and run it across the graph, if the ruler touches more than one point on the graph at one time, it is not a function.. but since the ruler did not touch more than one point at one time on both of these, they are both functions.
