Answer:
a. 15%
b. .73
c. 39/100, .39
d. .04, 4%
e. 77/100, 77%
f. 46/100, .46
g. .5, 50%
h. 6/100, 6%
i. 80/100, .8
j. .26, 26%
Step-by-step explanation:
Let's do the Fraction to Percent part first. Since all of the fractions have 100 in the denominator, this should be easy. The first one is 15/100 so this is just 15%, the next one is 73/100 and you can see that it is just 73%. It is the same way going from Percent to Fraction. On part f, we have 46%, so this will be 46/100.
For decimals, I recommend getting the percent first. I will use part f as my example again. You start with 46%. To make this a decimal, you just move the decimal point two spaces to the left. So, you end up with 0.46. To go from decimal to percent, you just move the point 2 spaces to the right.
IT ISNT THE 1st OR 2nd HELP LOOK AT IMAGE PLEASE
Answer:
Last option
Step-by-step explanation:
First method :
Red Line:
Take 2 coordinates through which the line passes. Let it be (0, 7) and (14, 0).
[tex]slope, m=\frac{ 0-7}{14-0} = -\frac{7}{14} = -\frac{1}{2}[/tex]
[tex]Equation : (y - 7) = -\frac{1}{2}(x)[/tex]
[tex]2y - 14 = -x\\2y + x = 14\\4y + 2x = 28[/tex] [tex][ multiply \ by \ 2 \ on \ both \ sides][/tex]
Blue Line:
Take coordinates through which the line passes.
Let it be (-4, -12) and (-10, -9).
[tex]slope, m = \frac{-9 + 14}{-10} = \frac{5}{-10} = -\frac{1}{2}[/tex]
[tex]equation : (y + 12) = -\frac{1}{2} (x+4)\\[/tex]
[tex]y = -\frac{1}{2}x - 2 - 12\\\\y = -\frac{1}{2}x -14\\\\2y = -x - 28\\\\-2y = x +28[/tex]
Second Method:
From the graph it is clear the lines are parallel. The slopes of line parallel to each other are equal. So convert each equation into standard line equation form :y = mx + b
And check for set of equation whose slope are same.
First set :
[tex]y = 10x - 15 \\\\=> slope = 10\\\\-9x + 2y = 10\\2y = 9x + 10\\\\y = \frac{9}{2}x + 5 => slope = \frac{9}{2}[/tex]
Slopes are not equal.
Second set :
[tex]2y = 2x + 5\\y = x + \frac{5}{2}\\slope = 1\\\\\\3x -4y = -5\\4y = 3x + 5\\\\\y = \frac{3}{4}x + \frac{5}{4}\\\\slope = \frac{3}{4}[/tex]
Slopes are not equal.
Third set :
[tex]y = 3x +10 \\slope = 3\\\\\\2x - 3y = -6\\3y = 2x +6\\\\y = \frac{2}{3}x + 2\\\\slope = \frac{2}{3}[/tex]
Slopes are not equal.
Fourth set :
[tex]2x + 4y = 28\\4y = -2x +28\\\\y = -\frac{1}{2}x + 7\\\\slope = -\frac{1}{2}\\\\\\-2y = x + 28\\\\y = -\frac{1}{2}x - 14\\\\slope = -\frac{1}{2}[/tex]
Slopes are same.

Three times a number increased by ten to equal to twenty less than six times the number. Find the number.
PLEASE HELP!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!
will mark brainlist.
Answer:
x =10
Step-by-step explanation:
3x + 10 = 6x -20
3x - 6x + 10 = -20
-3x + 10 = -20
-3x = -20 -10
-3x = -30
x = -30/-3
x = 10
Check:
3(10) + 10 = 6(10) - 20
30 + 10 = 60 - 20
40 = 40
If point P is Nine-elevenths of the distance from M to N, what ratio does the point P partition the directed line segment from M to N into?
9:2
9:9
9:11
9:13
Given:
Point P is Nine-elevenths of the distance from M to N.
To find:
The ratio in which point P partition the directed line segment from M to N.
Solution:
It is given that, point P is Nine-elevenths of the distance from M to N. So,
[tex]\dfrac{MP}{MN}=\dfrac{9}{11}[/tex]
It can be written as
[tex]\dfrac{MP}{MN}=\dfrac{9}{11}[/tex]
Let the lengths of MP and MN are 9x and 11x respectively. Then,
[tex]PN=MN-MP[/tex]
[tex]PN=11x-9x[/tex]
[tex]PN=2x[/tex]
Now,
[tex]\dfrac{MP}{PN}=\dfrac{9x}{2x}[/tex]
[tex]\dfrac{MP}{PN}=\dfrac{9}{2}[/tex]
[tex]\dfrac{MP}{PN}=9:2[/tex]
It means, point P divides the line segment MN in 9:2.
Therefore, the correct option is A.

What is the area and perimeter of square
Answer:
The answer is A
Step-by-step explanation:
This I because the area of a square is =
(length of on side)² = l²
The options there are not perfect squarss except A
which is 64 in²
And we know that 8² will give you 64
so then it means one side is 8 in
So the area =
8² = 8 in × 8 in = 64 in²
The circumference of a circle is 8.34cm. Find the length of the diameter. Give your answer rounded to 2 DP.
Answer:
Diameter, D = 2.65 cm
Step-by-step explanation:
Given the following data;
Circumference of circle = 8.34 cm
To find the length of its diameter;
Mathematically, circumference of a circle is equal to;
C = πD
Where;
C is the circumference of a circle.D is the diameter of a circle.Pie, π = 3.142Substituting into the formula, we have;
8.34 = 3.142 * D
[tex] D = \frac {8.34}{3.142} [/tex]
Diameter, D = 2.65 cm

What is constant of proportionality? I'm still having trouble understanding it. Can someone please give me a give problems and tell me how to find the COP (constant of proportionality) <3 thamks.
Answer:
See Explanation
Step-by-step explanation:
Given two variables (say x and y); the constant of proportionality is the ratio between these to variables.
Illustration; y is directly proportional to x
The above statement can be represented as:
[tex]y\ \alpha\ x[/tex]
When converted to an equation, you get
[tex]y\ =k x[/tex]
k, in the above equation, represents the constant of proportionality
Divide both sides by x to solve for k
[tex]k = \frac{y}{x}[/tex]
Take for instance: [tex]y = 3x[/tex]
Divide both sides by x
[tex]\frac{y}{x} = 3[/tex] --- 3 is the constant of proportionality

A study found a relationship between the number of sugary drinks consumed by a child each day and the prevalence of Type II diabetes. What is the dependent variable? The prevalence of Type II diabetes the number of sugary drinks consumed by a child during a day both the prevalence of Type II diabetes and the number of sugary drinks consumed by a child during a day there is no dependent variable
Answer:
A. The prevalence of Type II diabetes
Step-by-step explanation:
A. The prevalence of Type II diabetes
B. The number of sugary drinks consumed by a child during a day
C. Both the prevalence of Type II diabetes and the number of sugary drinks consumed by a child during a day
D. There is no dependent variable
The prevalence of Type II diabetes depends on number of sugary drinks consumed by a child each day
If
x = The prevalence of Type II diabetes
y = number of sugary drinks consumed by a child each day
Then,
x depends on y
The dependent variable is The prevalence of Type II diabetes

Find the x-intercept and y-intercept of the graph of the equation 2y = 3x - 6.
Given:
The equation is:
[tex]2y=3x-6[/tex]
To find:
The x-intercept and y-intercept of the graph of the given equation.
Solution:
We have,
[tex]2y=3x-6[/tex]
Substitute [tex]y=0[/tex] to find the x-intercept.
[tex]2(0)=3x-6[/tex]
[tex]0+6=3x[/tex]
[tex]\dfrac{6}{3}=x[/tex]
[tex]2=x[/tex]
So, the x-intercept of the graph of the given equation is 2.
Substitute [tex]x=0[/tex] to find the y-intercept.
[tex]2y=3(0)-6[/tex]
[tex]2y=-6[/tex]
[tex]y=\dfrac{-6}{2}[/tex]
[tex]y=-3[/tex]
So, the y-intercept of the graph of the given equation is -3.
Therefore, the x-intercept is 2 and the y-intercept is -3.

Find the measure of the missing angles. (someone help this is so urgent [cry])
Answer:
b=77
c = 103
Step-by-step explanation:
b and 77 are vertical angles and vertical angles are equal
b= 77
c and 77 are supplemental angles and supplemental angles add to 180
c+77 =180
c = 180-77
c =103
[tex] \large \sf \star \: \blue{Answer} \: \star[/tex]
[tex] \small \sf \mapsto\: b = \fbox{77 °} [/tex]
[tex] \small \sf \mapsto \: c = \fbox{ 103 °}[/tex]
Step-by-step explanation:Here,
Angle b and 77° both are vertical angles . So, both angles are equal . b = 77 °And,
Angle b and angle c are on straight line so it's supplementary angles and we know that sum of all angles of supplementary angles is 180 °.So, b + c = 180 °
77° + c = 180 ° ... { b = 77 -( vertical angle )}
subtract 77 from each sides
77 - 77 + c = 180 ° - 77 °
c = 103 °

Answer:
154 degrees
Step-by-step explanation:
A quadrilateral has the sum of the interior angles that is 360 degrees
for the tangent theorem we know that the angles where the lines intercept the circumference have a value of 90 degrees
x + 90 + 90 + 26 = 360
x + 206 = 360
x = 360 - 206
x = 154 degrees

y=-3/4x+3
Step-by-step explanation:
the slope is -3/4
in this case, y=mx+b
so y=-3/4x+b
