Find the circumference of the circle. You must show all work to get full credit. Don't forget to label your answer. Round to the nearest hundredth.
Answer:
c ≈ 26.39 yd
Step-by-step explanation:
The circumference of a circle can be found by multiplying the radius by 2 by pi or by multiplying the diameter by pi.
-> Since they give us the radius, I will use the more-known equation of 2πr
[Given]
c = 2πr
[Plug-in the value of r]
c = 2π(4.2 yd)
[Simplify]
c = 8.4yd * π
[Multiply]
c ≈ 26.39 yd
slope intercept form: y= -10/7x - 8/7
what is the standard form?
Answer:
10x+7y = -8
Step-by-step explanation:
Standard form is Ax + By + C = 0 or Ax + By = C.
The first step is everything is multipled by 7, witch gives you 7y=-10x-8.
To solve that, 10x to both sides must be added, to get 10x+7y-8
Explanation:
First we multiply everything by 7 to clear out the denominators.
We get to 7y = -10x - 8
Then add 10x to both sides to arrive at 10x+7y = -8
Standard form is Ax+By = C where A,B,C are integers
In this case we have: A = 10, B = 7, C = -8
Some math textbooks insist that A > 0.

Answer:
k = 2; y = 2·x·zx = 10; k = 2y = 192; y = 4·x·zz = 2; k = 3x = 48/9; k = 3/4Step-by-step explanation:
When we say "y varies jointly as x and z", we mean that y is proportional to x with some constant of proportionality, and also y is proportional to z with some constant of proportionality. The joint variation means that each "constant" of proportionality will depend on the other variable:
y = k·x·z
This can be solved for the different variables:
k = y/(x·z)
x = y/(k·z)
z = y/(k·x)
__
a)k = y/(x·z) = 30/(3·5) = 2; the equation is y = 2·x·z
b)k = 2 (read from the equation); x = y/(k·z) = 80/(2·4) = 10
c)y = k·x·z = 4·6·8 = 192; the equation is y = 4·x·z
d)k = 3 (read from the equation); z = y/(k·x) = 60/(3·10) = 2
e)k = 3/4 (read from the equation); x = y/(k·z) = 48/(3/4·12) = 48/9
Which of the following numbers has the correct number of significant digits for the sum of 4.0125 and 5.72?
A. 9.7324
B. 9.732
C. 9.73
D. 9.7
Answer:
the answer to your question is 9.73
Answer:
A
Step-by-step explanation:
Because according to my calculations there are supposed to be 5 digits and for the answers for the question A is the only letter with an answer with 5 digits.
My answer was 9.7325(even though the answers is different they still have the same number of digits) and for A it is 9.7324 which is another 5 digits.
Here is why I got 5 digits.
4.0125
5.7200
_______
When we add these we have to add 0er's to 5.72 because it doesn't have enough digits to add so you add zero's to it.
So 5 +0=5 2 +0=2 1 +2=3 0 +7=7 and for our last number 4 + 5=9 and so our answer is ?
9.7325
and the 9 = 1 digit 7=2 digit 3= 3 digits 2= 4 digits and last 5 = 5 digits.
Hope this helps have a great day:)
What is the slope of the line that passes through the points (-7, -8) and (-5, -6) ? Write your answer in the simplest form.
Answer:
[tex]m=1[/tex]
Step-by-step explanation:
Given the following question:
Point A = (-7, -8) = (x1, y1)
Point B = (-5, -6) = (x2, y2)
To find the answer we are going to have to use the formula for slope or rise over run.
[tex]m=\frac{y2-y1}{x2-x1}[/tex]
[tex]m=\frac{-6--8}{-5--7} =\frac{2}{2}[/tex]
[tex]\frac{2}{2} =1[/tex]
[tex]m=1[/tex]
Which means the slope of the line that passes through the points (-7, -8), (-5, -6) is "1."

A tub contains red, green and blue counters. There are 20 more red counters than blue counters and one-third of the counters are green. If there are 60 green counters what is the probability of picking a red counter?
Answer:
7/18
Step-by-step explanation:
If 1/3 of the counters are green that means that 60 counters are 1/3 of the total number of counters. We can multiply 60 by 3 to find the total number (3/3) of counters: 60 × 3 = 180
Next, we can find out how many counters are blue and green by subtracting 60 from 180: 180 - 60 = 120
If there are 20 more red counters than blue counters, we can write this algebraically as x + (x + 20) = 120. x + 20 is the number of red counters and x is the number of blue counters
To find x, simplify the equation:
2x + 20 = 120
2x = 100
x = 50
There are fifty blue counters, therefore there are 70 red counters. The probability of picking a red counter is 70/180 or 7/18.
Hope this helps!

420 cm²
540 cm²
Step-by-step explanation:
here is the answer. I just took th test
The area of the quilt that will be striped fabric is,
⇒ 420 cm²
What is Multiplication?To multiply means to add a number to itself a particular number of times. Multiplication can be viewed as a process of repeated addition.
Given that;
This figure represents a design being added to a quilt square.
And, Malcolm wants to add this design in a striped fabric to 12 quilt squares.
Now, The figure contain a triangle and a square shape.
Hence, We get;
Area of triangle = 1/2 (Base x Height)
= 1/2 (5 x 4)
And, Area of square = side²
= 5²
Hence, Total area of figure is,
⇒ 5 × 5 + 1/2 (5 × 4)
⇒ 25 + 10
⇒ 35 square units
Hence, The area of the quilt that will be striped fabric is,
⇒ 35 × 12
⇒ 420 cm²

What is an exponential expression?Powers can simply be expressed in concise form using exponential expressions. The exponent shows how many times the base has been multiplied. Since 2 is the "base" and 5 is the "exponent,"
It can be represented as 2x2x2x2=25 for the number 32. This phrase should be understood as "two to the fifth power."

Tim has read 10% of a book. He has 45 more pages to finish. How many pages are there in the book?
if Tim has read 10% of the book, that means he still hasn't read 90% of it yet, and we know that that 90% is 45 pages, so say the book has a total amount of pages of "x", which is 100%.

A pyramid and a prism share the same base. The prism has 99 edges. How many faces does the pyramid have
A pyramid is a three-dimensional object have one common point at the top. The pyramid will have 34 faces.
A pyramid's base form determines how many faces it has. Since the bases of the prism and the pyramid in this problem are identical, we may utilise the knowledge of the prism to ascertain the number of faces on the pyramid.
Three faces of a prism meet at each vertex. Since there are 99 edges on the prism in this instance, we can divide that number by 3 to get how many vertices there are.
99 ÷ 3 = 33
The pyramid has the same number of edges as the prism since its base is identical to that of the latter. The pyramid does, however, have a second face, which is the base itself.
Therefore, the pyramid has 33 + 1 = 34 faces.
