Leonard made the 3-d shape below for an art project. He wants to paint it blue.
How many square centimeters of paint does he need to paint the outside of every
side except for the bottom?
10 cm
6 cm
Answers
Answer:
90 [tex]cm^{2}[/tex] of blue paint
Step-by-step explanation:
From the given diagram, the sides have the same dimensions and the shape of a triangle.
Area of a triangle = [tex]\frac{1}{2}[/tex] x base x height
Given that, the base of each side = 6 cm, and the height = 10 cm.
Then,
Area of each side of the shape = [tex]\frac{1}{2}[/tex] x 6 x 10
= 30 [tex]cm^{2}[/tex]
Since Leonard wish to paint only the 3 sides and not the bottom part of the shape, the amount of paint required can be determined as;
3 x area of each side = 3 x 30
= 90 [tex]cm^{2}[/tex]
Leonard would need 90 [tex]cm^{2}[/tex] of paint to paint the sides of the shape.

Answers
Answer:
6/5
Step-by-step explanation:
If you are looking for the slope of the line it is 6/5 because starting from the origin you rise 6 (go up in this case) and run (go right in this case) 5 from the two points that you were given. The line is also going in an upwards direction so the slope is also positive. If you want to write the slope-intercept form equation you would use the slope intercept formula y=mx+b and plug in your slope (6/5) and your y-intercept, which is just 0 because it is at the origin and you would get y=6/5x or y=6/5x+0.
how do you solve 2x+4y=7 and -2x +3y=14
Answers
Answer:
y=3 x= -5/2
Step-by-step explanation:
simultaneous equations
2x + 4y = 7 ------ eq 1
-2x + 3y = 14 --------eq2
(different signs add)
(eq 2 + eq 1)
-2x +(-2x) = 0
4y+3y = 7y
7+14 = 21
7y= 21
(divide both sides by 7)
y= 21/7= 3
2x + 4(3) = 7
2x+ 12=7
2x = 7-12
2x = -5
x= -5/2

Find the lengths of the diagonals of QRST.
A.4
B.6
C.14
D.16
Answers
Answer:
C
Step-by-step explanation:
The diagonals of a rectangle are congruent, then
5x - 31 = 2x + 11 ( subtract 2x from both sides )
3x - 31 = 11 ( add 31 to both sides )
3x = 42 ( divide both sides by 3 )
x = 14
Then
RT = 2x + 11 = 2(14) + 11 = 28 + 11 = 39
The diagonals are each 39 units

Which equation best represents c, the total amount Mr. Thomas should be charged
for driving m miles?
Answers
Answer:
c = 0.15m + 45
Step-by-step explanation:
Generally, we have the equation of a straight line as;
y = mx + b
where m is the slope and b is the y-intercept
To get the value of m, we can use the slope equation
m = (y2-y1)/(x2-x1)
Let us select two points to use from the table
we have;
(40,51) and (20,48)
So substituting these values;
m = (48-51)/(20-40) = 0.15
So we have the partially completed equation as;
y = 0.15x + b
To get the value of b, we use any of the points
Using the last, we have
51 = 0.15(40) + b
b = 45
So we have the complete equation as;
y = 0.15x + 45
using the terms in the question, we have;
c = 0.15m + 45
