40x3= 120 -is the total of the three triangles
5x3=15- the total measure of the circle top part
120+15= 135
ANSWER: 135
BRAINLIST??
Answer:
148cm²
Step-by-step explanation:
seriously why, just why? okay, hold on, we're gonna be here a while
Let's start with the triangles, they're all equal, and we already have their measurements and the formula for the area of a triangle is base x height ÷ 2, so all we have to do is plug:
5 x 8 = 40
40 ÷ 2 = 20
Now we have to multiply by 3 because there's 3 of these abominations:
20 x 3 = 60
So we put that on a back burner while we do the semicircle
So the formula for the area of a circle is pi x radius², so we have to find the radius. We know that each of the triangle bottoms is 5cm, so we just multiply by 3:
5 x 3 = 15
So the diameter of the semicircle is 15cm, now we divide that by two to find the radius:
15 ÷ 2 = 7.5
Now we just plug that into our formula (we're using 3.14 for pi)
7.5² = 56.25
3.14 x 56.25 = 176.625
Usually, we'd stop there, but it's only half of a circle, so:
176.625 ÷ 2 = 88.3125
So now we add both of our areas:
60 + 88.3125 =
148.3125
Normally, that would be the answer, but since we're supposed to be estimating, we round it to the nearest whole number:
148.3125 -> 148
So the area of the figure is 148cm²
if this is wrong, let me know so I can fix it
hope this helps:)

Answer:
so for the first one, y=4x
meaning y = 4 times x
if y=1, x=4. y=2,x=8 y=3,x=12 etc..
same concept for the other ones.
y=x+6
x=1 then 1+6 = 7, so y=7
x=2 then 2+6 = 8, so y=8
etc

Answer:
See below
Step-by-step explanation:
7. Let's put points in this equation, 1, 2, and 3 will do.
y = 4x
y = 4(1)
y = 4
(1, 4)
y = 4x
y = 4(2)
y = 8
(2, 8)
y = 4x
y = 4(3)
y = 12
(3, 12)
Plot the points, and draw the line. See the first attached graph.
8. Let's put points in this equation, 1, 2, and 3 will do.
y = x + 6
y = 1 + 6
y = 7
(1, 7)
y = x + 6
y = 2 + 6
y = 8
(2, 8)
y = x + 6
y = 3 + 6
y = 9
(3, 9)
Plot the points, and draw the line. See the second attached graph.
9. Let's put points in this equation, 1, 2, and 3 will do.
y = 2x + 1
y = 2(1) + 1
y = 2 + 1
y = 3
(1, 3)
y = 2x + 1
y = 2(2) + 1
y = 4 + 1
y = 5
(2, 5)
y = 2x + 1
y = 2(3) + 1
y = 6 + 1
y = 7
(3, 7)
Plot the points, and draw the line. See the third attached graph.

What is Statistics?Statistics is the discipline that concerns the collection, organization, analysis, interpretation, and presentation of data.
A box plot or boxplot is a method for graphically demonstrating the locality, spread and skewness groups of numerical data through their quartiles.
The interquartile range (IQR) is the width of the box in the box-and-whisker plot.
For first box plot IQR=17-9
=8
For second box plot IQR=14-6
=8
For third box plot IQR=14-5
=9
For fourth box plot IQR=15-8
=7
Hence, the third box plot has the greatest interquartile range

Hey!
The area would be 13.85Step-by-step explanation:-
Area of a circle's equation is π[tex]r^{2}[/tex] (pi [tex]r^{2}[/tex])
Since the radius is 2.1 and value of pi is 3.14cm,
area is
[tex]2.1^{2}[/tex] x 3.14
4.41 x 3.14
= 13.85
The area of this circle is 13.6.
What is the area of the circle?Area of a circle is the region occupied by the circle in a two-dimensional plane.
The area of the circle is;
