Answer:
By doubling the dimension R, we'll actually change the area by a factor of 4 (it will become four times as large). Notice that this same change to the radius would only change the original circle's perimeter (2πR) by a factor of 2.
Step-by-step explanation:
\dfrac12(10x + 20y +10z) = 2 1 (10x+20y+10z)=start fraction, 1, divided by, 2, end fraction, left parenthesis, 10, x, plus, 20, y, plus, 10, z, right parenthesis, equals
Answer:
5x + 10y + 5z
Step-by-step explanation:
Given the expression
[tex]\frac{1}{2}(10x+20y+10z)\\[/tex]
Expand the parenthesis using the distributive law;
[tex]\frac{1}{2}(10x)+ \frac{1}{2}(20y)+\frac{1}{2}(10z)\\= \frac{10x}{2} + \frac{20y}{2} + \frac{10z}{2}\\= 5x + 10y + 5z[/tex]
Hence the required solution is 5x + 10y + 5z
Water makes up about 60% of the average adult's body weight. Represent this percent by shading in the squares.
Answer:
shading three boxes
Step-by-step explanation:
It is given that :
The body weight of an average adult = 60%
We have to show this by shading the square boxes shown.
There are 5 square boxes in total which makes up 100%.
So divide 100 by 5, we can 20% for each box.
So, 20% + 20% + 20% will give us 60%
Therefore, shading three boxes will give us 60% which is the water percent in an average adult's body weight.
This is represented by the figure below.

What is the length of EF in the right triangle below?
Can you please help me.
Answer:
Sin A = 5/13; tan C = 12/5
Step-by-step explanation:
Sin = opposite / hypotenuse. The opposite of A is 5, and the hypotenuse is 13, therefore Sin A = 5/13.
Tan = opposite / adjacent. The opposite of C is 12, and the adjacent is 5, so tan C = 12 / 5
An unknown number is not equal to 3.6 but rounds to 3.6 when rounded to the nearest tenth, what could be the number?
Answer:
3.55-3.59
Step-by-step explanation:
to round off to the nearest whole number, look at the first number after the decimal, if it is less than 5, add zero to the units term, If it is equal or greater than 5, add 1 to the units term.
So numbers that would be rounded off to 3.6 have to have an hundredth value equal or greater than 5
they include
3.55
3.56
3.57
3.58
3.59

Hzjwnsjwnziqnnsjansnsjans
Answer:
Step-by-step explanation:
Slope of line passing through [tex](x_1,y_1)[/tex] and [tex](x_2,y_2)[/tex] is given by,
m = [tex]\frac{y_2-y_1}{x_2-x_1}[/tex]
From the graph attached,
Slope of the line passing through (-3, 0) and (0, 5) = [tex]\frac{5-0}{-3-0}[/tex]
= [tex]-\frac{5}{3}[/tex]
Line passing through a point (h, k) and slope 'm' will be,
y - h = m(x - k)
Since, line passing through (11, 0) is parallel to the line given in the graph,
Slope of the parallel line will be same as [tex]-\frac{5}{3}[/tex]
Equation of a line passing through (11, 0) and slope = [tex]-\frac{5}{3}[/tex]
y - 0 = [tex]-\frac{5}{3}(x-11)[/tex]
y = [tex]-\frac{5}{3}(x-11)[/tex]
Now satisfy this equation with the points given in the options,
Option (1)
For (1.67, -15.59),
-15.59 = [tex]-\frac{5}{3}(1.67-11)[/tex]
-15.59 = -15.55
False.
Therefore, given point doesn't lie on the line.
Option (2)
For (-0.33, -13.59)
-13.59 = [tex]-\frac{5}{3}(-0.33-11)[/tex]
-13.59 = -18.88
False
Option (3)
For (0.67, -18.59),
-18.59 = [tex]-\frac{5}{3}(0.67-11)[/tex]
-18.59 = 17.22
False
Option (4)
For (1.67, -15.59)
-15.59 = [tex]-\frac{5}{3}(1.67-11)[/tex]
-15.59 = -15.55
False.
Therefore, none of the points given in the options are lying on the line.

I need help can someone explain this question to me?
If the diameter is 26 inches, what is the radius
Answer:
13 inches
Step-by-step explanation:
In any circle, the radius is always half of the diameter.
So, the diameter can be found by multiplying the radius by 2, and the radius can be found by dividing the diameter by 2.
Since the diameter is 26 inches, we can divide this by 2 to get the radius
26/2
= 13
The radius is 13 inches
Answer:
[tex] \bf \huge13[/tex]
Step-by-step explanation:
Given that : the diameter is 26 inches.to find :what is radius .formulas used :radius = diameter / 2explanation :we know that,
finding the radius
⟼ diameter = 26 inches
⟼ radius = diameter / 2
⟼ radius = 26 / 2 inches
⟼ radius = 13 / 1 inches
⟼ radius = 13 inches.
∴ radius is 13 inches .
