What is the circumference of circle with diameter 7 cm?
Answer:21.99
Step-by-step explanation: Given diameter of a circle is(d)=7cm.
Now, we know that circumference of circle is =πd, where d is diameter of circle.
So, here circumference is = π×7cm
= 22/7 x 7 cm
Circumference = 22cm
[tex]\sf \bf {\boxed {\mathbb {GIVEN:}}}[/tex]
Diameter of the circle "d" = 7 cm
[tex]\sf \bf {\boxed {\mathbb {TO\:FIND:}}}[/tex]
The circumference of the circle.
[tex]\sf \bf {\boxed {\mathbb {SOLUTION:}}}[/tex]
[tex]\sf\orange{The\:circumference \:of\:the\:circle\:is\: 22\:cm.}[/tex]
[tex]\sf \bf {\boxed {\mathbb {STEP-BY-STEP\:EXPLANATION:}}}[/tex]
We know that,
[tex]\sf\purple{Circumference\:of\:a\:circle \:=\:πd }[/tex]
[tex] = \frac{22}{7} \times 7 \: cm[/tex]
[tex] = 22 \: cm[/tex]
Therefore, the circumference of the circle is 22 cm.

A bag contains 10 red marbles, 7 blue marbles, and 3 green marbles. You randomly select a marble from the bag, record the color, and then put that marble back in the bag. If you were to do this 200 times, how many times would you expect to pull out a blue marble?
Answer:
70
Step-by-step explanation:
We have 7 blue marbles, and 20 total marbles. As a result, if we randomly chose one marble from the bag, the probability would be (number of favorable outcomes)/(number of total outcomes) = 7/20.
This means that for each 20 trials, we would expect to pull out a blue marble 7 times, as the probability does not change over time (because we put the marbles back, there are the same amount of each marble). Over 200 trials, we can simply make it out of 200 instead of 20. We can thus multiply 7/20 by 10/10 (10/10 is equal to 1, keeping the proportions equal) to get 70/200, so we can expect 70 blue marbles out of 200.

with what other binomial?
(1) 4x-7
(3) 2x-7
(2) 2x-9
(4) 4x-9
Answer:
option 3 : (2x - 7 )
Step-by-step explanation:
ax + bx = x(a+ b)
a(x+ y) + b(x+y) = (x+y)(a+b)
[tex](3x - 8 ) ( 2x + 5) - (x + 1)(2x + 5)\\\\(2x+5)[ (3x - 8) - (x+1) ][/tex] [ (2x + 5) is common is both terms ]
[tex](2x+ 5)(3x -8 -x + 1)\\\\(2x+ 5)(2x - 7)[/tex]
Therefore , the binomial is ( 2x - 7)

Maggie used the commutative property to write StartFraction 4 Over 5 EndFraction + 6.9 y minus 8 as the equivalent expression 6.9 y + 8 minus StartFraction 4 Over 5 EndFraction. Did Maggie apply the commutative property correctly? Why or why not?
Answer:
Maggie did not apply the law correctly
Step-by-step explanation:
Given 3 numbers A, B and C, for a commutative property
(A+B)+C = C+(A+B)
This shows that the remains the same no matter what values comes first
For the given expression
4/5+6.9y-8 = 6.9y+8-4.5
The values are not commutative because of the presence of negative sign. For the expression to be commutative, they must be equal no matter the way it is arranged and the sign must be positive all through for both sides. Hence Maggie did not apply the law correctly

Answer: 30
Step-by-step explanation: So clearly we want 45 to be divided into x and 2x. Because the sum of the two parts is 45, so x + 2x = 45 which gives us the value of x = 15.
So the boy has 15 while the girl has 30
If f(x) is parallel to the line y= 3/4 x + 2/5 which function could be f(x)
Answer:
If f(x) is parallel to the line y=3/4x+b ,it would have to have the same slope.
In this equation:
y=mx+b
m= is the slope of the line.
A line parallel to the line y=3/4x +2/5 must have the same slope; that it is to say, the slope would be m=3/4
Examples:
y=3/4 x+ 50000
y=3/4 x -51/36
y=3/4 x -√2
These functions could be parallels to the line y=3/4 x +2/5
Answer:
see below.
Step-by-step explanation:
The key to this question is the factor 3/4. So anything that is going to make the coefficient in front of x = to 3/4 is a possible answer.
y = 3/4x + b where b is anything but 2/5 is one answer. Disguised but still likely is
4y = 3x + b Where you could divide everything by 4
y = 3/4x + b/4
Even something like
-4y = - 3x + b is possible because when you divide by -4, you get
y = -3x/-4 + b/-4
y = 3x/4 - b/4
Simplify using the identity −2 /7 x 1/5 + 1/3 - 4/5 x - 2/7
Answer:
1/3 + 6/35
Step-by-step explanation:
We are given;
−2/7 × 1/5 + 1/3 - 4/5 × -2/7
Using the rule of bodmas, we will group them and solve with multiplication being the first operation.
1/3 - (4/5 × -2/7) + (−2/7 × 1/5)
Factorization of first and second bracket gives;
1/3 + 2/7(4/5) + 2/7(-1/5)
Factorizing again gives;
1/3 + 2/7(4/5 - 1/5)
>> 1/3 + 2/7(3/5)
>> 1/3 + 6/35

Point CC is located at (4,3)(4,3) on the coordinate plane. Point CC is reflected over the xx-axis to create point C'C ′ . Point C'C ′ is then reflected over the yy-axis to create point C''C ′′ . What ordered pair describes the location of C''?C ′′ ?
Answer:
[tex]C" = (-4,-3)[/tex]
Step-by-step explanation:
Given
[tex]C = (4,3)[/tex]
Required
The coordinates of C"
From the question, we understand that:
C is reflected over x-axis to give C'
The rule to this is:
[tex]C(x,y) \to C'(x,-y)[/tex]
So, we have:
[tex]C(4,3) \to C'(4,-3)[/tex]
Next, C' is reflected over y-axis to give C''
The rule to this is:
[tex]C'(x,y) \to C"(-x,y)[/tex]
So, we have:
[tex]C'(4,-3) \to C"(-4,-3)[/tex]

X= kilometers by bike
Y= kilometers by bus
How many kilometers did they travel by bike?
Answer:
430 km
Step-by-step explanation:
If they traveled 350 km by bus and biked 80 km more than they were bused, then,
Traveled by bus, Y = 350 km
Traveled by bike, X = 350 + 80 = 430 km

A researcher asks participants to rate the tastes of three different cola drinks. The size, shape, and color of the drink cups are the same for each drink. In this study, the independent variable is __________, the dependent variable is __________, and an extraneous variable is __________. Group of answer choices drink cups, taste rating of cola drink, type of cola drink type of cola drink, drink cups, taste rating of cola drink type of cola drink, taste rating of the cola drink, drink cups drink cups, type of cola drink, taste rating of cola drink
Answer:
Independent variable - type of cola drink
dependent variable - taste rating of cola drink
extraneous variable - type of cola drink
Step-by-step explanation:
The independent variable is the variable that the person carrying out an experiment changes or manipulates. the independent variable usually have a direct effect on the dependent variable
The dependent variable is the variable that is being measured in an experiment. It is usually affected by the independent variable.
The extraneous variable is the variable that is not been researched in the experiment but it has the potential to influence the results of the experiment.
The type of cola drink given to participants can be manipulated to derive different ratings. the ratings that participants would give the cola drink is determined by the type of cola drink served. Here, the type of drink served is the independent variable while the ratings given is the dependent variable.
the extraneous variable is the type of drink cups used. this is not relevant to the experiment but can affect the results of the experiments. for example, imagine a red cup is used for the experiment and a participant hates red cups. it is more likely that the participant would give a low rating for the cola drink even if the drink tastes good

ok so if they are congreant that mean the
x=38
Answer:
38
Step-by-step explanation:
Because both x and the 38° can create a linear pair with the same angle, they must be equal. Linear pairs are equal to 180°
Name the bottom angle C.
X + C = 180 (linear pair)
38 + C = 180 (linear pair)
X + C = 38 + C Subtract C from both sides
X = 38

James fenced in his backyard. The perimeter of his fence is 20 feet, and the width of his yard is 2 feet wide. Use the perimeter formula to find the length of his rectangular yard
in inches: P2L+2W.
Answer:
Length = 8 feet
Step-by-step explanation:
Perimeter = 2 x ( length + width )
20 = 2 x (length + 2)
10 = Length + 2
10 - 2 = Length
Therefore, Length = 8 feet
