Answer:
20%
Step-by-step explanation:
or 20 because since there is 5 and 3 you ad them and you get 5, 5+5 =10 and its like 100 but its not so, 2 of 10 is like saying 20% of 100
Answer:
40
Step-by-step explanation:
200/10=20
There are 2 blue marbels so 20x2=40

The volume of a sphere is two-thirds of a cylinder. What is the volume of a cylinder that has the same diameter as a sphere with a volume of 14 u^3, in u^3
Answer:
[tex]V_2= \frac{28}{3} u^3[/tex]
Step-by-step explanation:
Given
Represent the volume of the cylinder with V1 and the volume of the sphere with V2
So, from the first statement: we have:
[tex]V_2 =\frac{2}{3}V_1[/tex]
and
[tex]V_1 = 14u^3[/tex]
To solve for [tex]V_2[/tex], we simply substitute [tex]14u^3[/tex] for [tex]V_1[/tex] in [tex]V_2 =\frac{2}{3}V_1[/tex]
[tex]V_2 =\frac{2}{3}V_1[/tex]
[tex]V_2= \frac{2}{3} * 14u^3[/tex]
[tex]V_2= \frac{2* 14}{3} u^3[/tex]
[tex]V_2= \frac{28}{3} u^3[/tex]
Hence, the volume of the sphere is [tex]\frac{28}{3} u^3[/tex]

What happens during photosynthesis?
a) carbohydrates are released into bloodstream
b) carbon dioxide is released into air
c) an organism captures energy in sunlight and uses to make its own food
d) glucose is broken down releasing energy
Answer:
C During the process of photosynthesis, cells use carbon dioxide and energy from the Sun to make sugar molecules and oxygen. ... Then, via respiration processes, cells use oxygen and glucose to synthesize energy-rich carrier molecules, such as ATP, and carbon dioxide is produced as a waste product

If a point, ray, line, line segment, or plane intersects a segment at its midpoint, then it is?
Answer:
If A Point, Ray, Line Segment, or Plane intersects a segment at its midpoint, then it Bisects the segment.
Step-by-step explanation:A segment, ray, line, or plane that is perpendicular to a segment at its midpoint is called a perpendicular bisector. If a point is on the perpendicular bisector of a segment, then it is equidistant from the endpoints of the segment. Point is equidistant from two points if its distance from each point is the same.

(-3 -5)/(9+5)= -8/14= -4/7
y - 5 = -4/7(x + 5)
y - 35/7 = -4/7x - 20/7
y = -4/7x + 15/7

What type of quadrilateral is ABCD? Move segments and words to blanks to classify quadrilateral ABCD
The quadrilateral that is illustrated based on the information and diagram is a square.
What is a quadrilateral?A quadrilateral is a plane figure with four edges and four corners, also known as vertices. The quadrilateral's four vertices or corners all have angles. A quadrilateral has four straight sides and is a two-dimensional shape. Parallelograms, trapezoids, rectangles, kites, squares, and rhombuses are a few examples of quadrilaterals.
A quadrilateral with four equal sides and angles is called a square. Due to its equal sides and angles, it is also a regular quadrilateral. A square has four 90° angles, just like a rectangle does. It can also be thought of as a rectangle with equal lengths on its two adjacent sides. A square is a quadrilateral with four equal sides and four equal angles that is a regular quadrilateral. The square's angles are at a right angle or 90 degrees.

Find the slope of the line
Answer:
The slope of the line is: 3
Step-by-step explanation:
Given the points
(-3, -6) and (3, 12)
Determine the slope between (-3, -6) and (3, 12) using the formula
[tex]m=\frac{y_2-y_1}{x_2-x_1}[/tex]
where
m is the slope between (x₁, y₁) and (x₂, y₂)
In our case,
(x₁, y₁) = (-3, -6)(x₂, y₂) = (3, 12)now substitute (x₁, y₁) = (-3, -6) and (x₂, y₂) = (3, 12) in the slope formula
[tex]m=\frac{y_2-y_1}{x_2-x_1}[/tex]
[tex]m=\frac{12-\left(-6\right)}{3-\left(-3\right)}[/tex]
[tex]m=\frac{12+6}{3+3}[/tex]
[tex]m=\frac{18}{9}[/tex]
[tex]m=3[/tex]
Therefore, the slope of the line is: 3
Find the equation of a line that contains the points (4,−1) and (−1,−4). Write the equation in slope-intercept form, using fractions when required.
Answer:
y = 3/5x - 17/5
Step-by-step explanation:
slope formula: (y₂ - y₁) / (x₂ - x₁)
First, plug in these values of the two given points.
(-4 - (-1)) / (-1 - 4)
Simplify within the parentheses.
(-4 + 1) / (-1 - 4)
(-3) / (-5)
3/5
This is your slope. Plug this into a standard slope-intercept equation: y = mx + b
To find b, we want to plug in a value that we know is on this line: in this case, I will use the second point (-1, -4). Plug in the x and y values into the x and y of the standard equation.
-4 = 3/5(-1) + b
Multiply.
-4 = -3/5 + b
Add 3/5 to both sides. -- To add it easier, convert 4 to a have a denominator of 5.
-20/5 = -3/5 + b
-20/5 + 3/5 = b
-17/5 = b
Now, plug this into your standard equation.
y = 3/5x - 17/5
Check this equation by plugging in the other point you did not use (4, -1)
-1 = 3/5(4) - 17/5
-1 = 12/5 - 17/5
-1 = -5/5
-1 = -1
Your answer is correct!
Hope this helps!

B) 10:28
C) 36:48
D) 5:21
Answer:
it's actually none of these.
Step-by-step explanation:
if we divide 15 by 3 we also have to divide 42 by 3. We end up with 5:14. 15 isn't divisible by any number other than 1, 3, 5, and 15.

The slope of the line is 4.
Convert the equation `5x+2y=-8`into slope-intercept form.
Answer:
y= -2.5x-4
Step-by-step explanation:
we have to isolate our y
subtract 5x from 5x+2y=-8 and move it to the right side
2y= -5x-8
divide everything by 2
y=-2.5x-4

Write a Linear Equation in
Point-Slope Form.
m = -5
(-3, – 7)
==================================
Work Shown:
m = -5 is the slope
(x1,y1) = (-3,-7) is the point the line goes through
Plug this into the point slope form below and simplify.
y - y1 = m(x - x1)
y - (-7) = -5(x - (-3))
y + 7 = -5(x + 3)
Side note: If we solved for y, we'd get y = -5x - 22 showing that -22 is the y intercept.
