Answer: B. Graph of 2 lines that intersect at one point. Both lines are solid. One line passes through (-2,2) and (0,3) and is shaded below the line.
y < = 1/2x + 3...(-2,2) y < = 1/2x + 3....(0,3)
2 < = 1/2(-2) + 3 3 < = 1/2(0) + 3
2 < = -1 + 3 3 < = 0 + 3
2 < = 2 (correct) 3 < = 3 (correct)
The other line passes through points (0,1) and (1,-2) and is shaded above the line.
y > = -3x + 1...(0,1) y > = -3x + 1...(1,-2)
1 > = -3(0) + 1 -2 > = -3(1) + 1
1 > = 0 + 1 -2 > = -3 + 1
1 > = 1 (correct) -2 > = -2 (correct)

What is the probability of pulling a heart
52 cards and 13 hearts
and rolling an even number on a dice
Answer: The probability of drawing a heart out of the deck is 13/52, or 1/4. The probability of drawing an even number as card #2 (c∈{2,4,6,8,10}) for any suit is 20/51, except when the first card drawn is an even heart, then the probability of the second draw is 19/51.

The volume of a right rectangular prism is 70 7/8 cubic feet and its base is a square with a side length of 4 1/2 feet. what is the height?
Answer:
7/2 feet
Step-by-step explanation:
Volume of Right Rectangular Prism: V = w * h * l
You are given the volume, and the base (which would include l and w)- and are told to find h.
70 7/8 cubic feet = 4 1/2 feet * h * 4 1/2 feet (simplify the right side)
70 7/8 cubic feet = 81/4 feet squared * h (divide both sides by 81/4)
7/2 feet = h
The height will be 7/2

9514 1404 393
Answer:
28 square units
Step-by-step explanation:
The figure can be decomposed several ways. Maybe easiest to see is as a 8×4 rectangle with a 2×4 right triangle cut from the corner.
The area of the rectangle is ...
A = LW = (8)(4) = 32
The area of the missing triangle is ...
A = 1/2bh = 1/2(2)(4) = 4
Then the area of the shaded figure is ...
32 - 4 = 28 . . . square units
_____
Alternate solution
If you divide the figure with a horizontal line across the middle, it becomes a 4×4 square and a trapezoid with bases 2 and 4 and height 4. The shaded area is the sum of these areas.
The area of a trapezoid is ...
A = 1/2(b1 +b2)h
A = (1/2)(2 +4)(4) = 12
The area of the square is ...
A = s² = 4² = 16
Then the total area is ...
12 +16 = 28 . . . square units
What is the width of this rectangular prism if the volume is 162 cm cubed?
A. 3 cm.
B. 3 cm. squared
C. 3 cm. cubed
D. 108 cm.
Answer:
A 3 cm
Step-by-step explanation:
Volume is lxwxh, 6x9= 54, and 54x3=162
Answer: 3
Step-by-step explanation:
The equation for volume of a rectangular prism is lwh. We have the lh and 6 times 9 is 54. Now we just divide 162 and 54 and that's the width which is 3. And to double check 3 times 9 times 6 is 162 :)
The sum of a number r and 10 is −2.
R=? D=? C=\pi[/tex]
Pls help and show your work for brainlist .
Answer:
R=? D=? C=\pi[/tex]
Step-by-step explanation:
R is a radius, the radius is a line segment from the center of a circle.
D is a distance around. Another word for D is the perimeter.
Pi is a circle's circumference (Which never ends.)
For example: 3.1415926535 8979323846 2643383279 5028841971 6939937510 5820974944 5923078164 0628620899 8628034825 3421170679...
And the pi is 31,415,926,535,897.
Pi meaning is a half-radius x half-radius x circumference.

Answer:
8: 73.2 cm
10: 738 mm
Step-by-step explanation:
8: A= 12.2 (4.5 + 7.5) / 2 --> 146.2 / 2 = 73.2 cm
10: A= 36 (22 + 19) / 2 --> 1,476 / 2 = 738 mm
Answer:
8: 73.2
10: 738
Step-by-step explanation:
Area of a trapezoid = [tex]A=\frac{a+b}{2} h[/tex]
where a and b = base lengths and h = height
For #8
These are the given dimensions
Base 1 = 4.5
Base 2 = 7.5
Height = 12.2
All we have to do is plug in the values into the formula
So....
[tex]A=\frac{4.5+7.5}{2} 12.2\\4.5+7.5=12\\\frac{12}{2} =6\\6*12.2=73.2[/tex]
Hence the answer is 73.2cm²
For #10
Once again all we have to do is plug in the values into the formula
[tex]A=\frac{22+19}{2} 36\\22+19=41\\\frac{41}{2} =20.5\\20.5*36=738[/tex]
Hence the answer is 738

Jasraj left his house and walked 1500 m east to the supermarket. He then walked another 500 m east to the comic store before walking back home the same way he came. How many kilometers did Jasraj walk altogether?
Answer:
Jasraj walked 4 kilometers all together
Step-by-step explanation:
First, add.
1,500 + 500 = 2,000
Then, multiply by 2.
2,000 × 2 = 4,000
Now, we have to convert to kilometers.
1 kilometer = 1000 meters
4,000 ÷ 1,000 = 4
So, Jasraj walked 4 kilometers!

If 30% of a number equals 8, find 90% of that number.
Answer:
8.88
Step-by-step explanation:
I believe it is 8.88 becuase this question is asking to find 90% pf that number.
What do you need to do?
you have to make a proportion.
8/x 90/ 100
You would now cross multiply. 90* x = 90x 8*100= 800
the equation you would need is 90x = 800. divide them and you get 8.88.
ROUNDED: you get 9.
I believe this is correct sorry if it was incorrect.
