Answer:
Refer to the attachmenT
Have a good day Ahead:)
Answer:
6
Step-by-step explanation:
Because circumference is 2pir, the 12 is multiplying the radius by 2. To get the radius divide 12 by 2 to equal 6.

with slope –1/4, passing through (-4, -1)
Answers
Answer:
[tex]y = -\frac{1}{4}x - 2[/tex]
Step-by-step explanation:
i'm not sure if you're trying to find the equation of the line ?? but i'll assume that's the case and find the slope-intercept form equation of the line.
slope intercept form is [tex]y = mx + b[/tex], where [tex]m[/tex] is the slope and [tex]b[/tex] is the y-intercept. since the slope is already identified, you can plug in [tex]-\frac{1}{4}[/tex] for [tex]m[/tex].
[tex]y = mx + b[/tex] ⇒ [tex]y = -\frac{1}{4}x+b[/tex]plug in the [tex]x[/tex] and [tex]y[/tex] values from the coordinate pair that passes through the line, which is (-4, -1). you can start with either [tex]x[/tex] or [tex]y[/tex], but i'm going to start with [tex]x[/tex].
first, plug in [tex]-4[/tex] for [tex]x[/tex].
[tex]y = -\frac{1}{4}x+b[/tex] ⇒ [tex]y = -\frac{1}{4}(-4)+b[/tex]now plug in [tex]-1[/tex] for [tex]y[/tex].
[tex]y = -\frac{1}{4}(-4)+b[/tex] ⇒ [tex]-1 = -\frac{1}{4}(-4)+b[/tex]after plugging in all of the given values, the equation is now [tex]-1 = -\frac{1}{4}(-4)+b[/tex], in which you need to solve for [tex]b[/tex].
now it's time to solve! begin by multiplying [tex]-\frac{1}{4}(-4)[/tex] in order to simplify the right side of the equation.
[tex]-\frac{1}{4}(-4) = 1[/tex]you now have [tex]-1 = 1 + b[/tex]. subtract 1 from both sides of the equation. on the right side, it cancels itself out, leaving you with [tex]b[/tex]. on the left side of the equation, you now have [tex]-1 - 1[/tex], which equals [tex]-2[/tex].
therefore [tex]-2 = b[/tex], or [tex]b = -2[/tex].
now that you've solved for your [tex]b[/tex] value, plug it into your initial slope-intercept form equation!
[tex]y = -\frac{1}{4}x + b[/tex] ⇒ [tex]y = -\frac{1}{4}x - 2[/tex]if you want to check to make sure that the values are correct, plug (-4, -1) into your completed slope-intercept form equation. as you did in the beginning, plug in [tex]-4[/tex] for [tex]x[/tex] and [tex]-1[/tex] for [tex]y[/tex].
[tex]y = -\frac{1}{4}x - 2[/tex] ⇒ [tex]-1 = -\frac{1}{4}(-4) - 2[/tex]begin simplifying by multiplying [tex]-\frac{1}{4}(-4)[/tex].
[tex]-1 = -\frac{1}{4}(-4) - 2[/tex] ⇒ [tex]-1 = 1 - 2[/tex]subtract [tex]1 - 2[/tex].
[tex]-1 = 1 - 2[/tex] ⇒ [tex]-1 = -1[/tex]since both sides of the equation are equal, that means your [tex]b[/tex] value of [tex]-2[/tex] is correct because it makes the equation true!

Answer:
The heights, in feet, of the trees for sale at two nurseries are shown below.
Yard Works: 7, 9, 7, 12, 5
The Grow Station: 9, 11, 6, 12, 7
Which statements are true regarding the measures of center and variability of these data sets? Select three choices.
________________________________________________________
1 The mean of the tree heights at Yard Works is less than the mean of the tree heights at The Grow Station.
2 The median of the tree heights at Yard Works is greater than the median of the tree heights at The Grow Station.
3 The range of the tree heights at Yard Works is greater than the range of the tree heights at The Grow Station.
4 The mean absolute deviation of the tree heights at Yard Works is greater than the mean absolute deviation of the tree heights at The Grow Station.
5 The mean absolute deviation of the tree heights at Yard Works is equal to the mean absolute deviation of the tree heights at The Grow Station.
Step-by-step explanation:
Yard works has...
mean=8
median=7
mode=7
range=11
because in order it is 5 7 7 9 12
(5+7+7+9+12)/5=8
5 7( 7 )9 12 is the median
and seven occurs the most
and with this logic...
THE GROWSTATION has a
mean=9
median=9
mode=n/a
range=6
_______________________________________
YEA) The mean of the tree heights at Yard Works is less than the mean of the tree heights at The Grow Station.
YEA) The median of the tree heights at Yard Works is greater than the median of the tree heights at The Grow Station.
YEA) The range of the tree heights at Yard Works is greater than the range of the tree heights at The Grow Station.
The mean absolute deviation of the tree heights at Yard Works is greater than the mean absolute deviation of the tree heights at The Grow Station.
The mean absolute deviation of the tree heights at Yard Works is equal to the mean absolute deviation of the tree heights at The Grow Station.

The radius of a circle is 3 m. Find its circumference in terms of pi
Answers
Gotcha, bro.
(I don't know what pi is, so I'm gonna assume that it is 3.14)
C=pi x diameter
First, multiply the radius by 2 so you have the diameter.
3x2=6
Second, multiply 3.14 (pi) by 6 (diameter)
3.14x6=18.84
Therefore, the circumference is 18.84.
(19 if you round it to the whole number)
Hope this helps!

The circumference of the circle is 6π meters.
What is a circle?A circle is a two dimensional figure with a radius and circumference of 2πr.
We have,
The circumference of a circle is given by the formula:
C = 2πr
where r is the circle's radius and π (pi) is a mathematical constant approximately equal to 3.14.
In this case, the radius of the circle is 3 meters.
Substituting this value in the formula, we get:
C = 2πr
C = 2π(3)
C = 6π
Therefore,
The circumference of the circle is 6π meters.

Me. Watson is making 34.6 fluid once's of red paint and 18.6 fluid ounces of yellow paint to make orange paint. How many 3.5- fluid once jars can she fill?
Answers
Answer: She can fill about 15 3.5- fluid once jars.
Step-by-step explanation:
Given:
Quantity of red paint = 34.6 fluid ounces
Quantity of yellow paint = 18.6 fluid ounces
Total quantity of orange color = (Quantity of red paint )+(Quantity of yellow paint )
= (34.6+18.6) fluid ounces
= 53.2 fluid ounces
Number of 3.5- fluid ounce jars she can fill = (Total quantity of orange color) ÷ 3.5
= 53.2÷3.5 = 15 (approx)
Hence, She can fill about 15 3.5- fluid once jars.

Cos=Adjacent over Hypotenuse
Tan=Opposite over Adjacent
The red arrows on the attachment indicate where opposite, hypotenuse, and adjacent are for angle A.
So in this case, the sin of angle A (opposite over hypotenuse) would be [tex]\frac{24}{26}[/tex] and cos A (adjacent over hypotenuse) would be [tex]\frac{10}{26}[/tex].
