What is the volume of a rectangular prism with a height of 1.5 feet and a base area of 4.5 square feet use the formula V=Bh
Step-by-step explanation:
you can use that same formula to answer that same question
The volume of the rectangular prism is [tex]6.75ft^{3}[/tex]
Diagram of a rectangular prism is shown in the attachment below.
Given that:
the height (h) = 1.5 ft
base area (B) = 4.5 sq ft
Volume of rectangular prism (V) [tex]= Bh[/tex]
Plug in the known values into the formula:
[tex]V = 4.5 \times 1.5\\V = 6.75 ft^{3}[/tex]

How many solutions does the system have?
5y = 15x - 40
y = 3x -8
A. Infinitely many solutions
B. No solutions
C. Exactly one solution
Answer:
A; infinitely many solutions
Step-by-step explanation:
first, let's simplify the first equation to make it simpler.
divide both sides by 5
y=3x-8
new system
y=3x-8
y=3x-8
as you can see, they are the same.
not mandatory but useful!⬇⬇⬇⬇
just to be more clear, let's substitute them. since they're both already in y=, we can make them both set to each other.
3x-8=3x-8
add 8 to both sides; subtract 3x from one side
0=0
the answer is A, Infinitely many solutions.

Angela wants to know how many families in her neighborhood plan to attend the parade. She puts all 120 of the neighborhood addresses in a hat and draws a random sample of 30 addresses. She then asks those families if they plan to attend the parade. She finds that 40% of the families plan to attend the parade. She claims that 40% of the neighborhood families would be expected to attend the parade. Is this a valid inference? (5 points)
A) Yes, this is a valid inference because the 30 families speak for the whole neighborhood
B) Yes, this is a valid inference because she took a random sample of the neighborhood
C) No, this is not a valid inference because she did not take a random sample of the neighborhood
D) No, this is not a valid inference because she asked only 30 families
The basketball game lasted 1 hour and 40 minutes. If the game started at 7:30 p.m., what time did it end?
(Answer:_:__)
Answer:
9:10pm
Step-by-step explanation:
the game ended at 9:10pm
Answer:
21:10 (24-hour clock) or 9:10 ( 12-hour clock)
Step-by-step explanation:
Two ways it can be solved:
Starting time: 7:30
Game lasted- 1 hour and 40 minutes
Ending time-?
7:30 is converted to 24 hrs timing clock:∴ hr I min
7 : 30 pm
+ 12 : 00
___________
= 19 : 30
Then, hr I min
19 : 30
+ 1 : 40
______________
= 20 : 70
+ 1 : - 60
______________
= 21 : 10
So it ended at 21:10 (24-hour clock) or 9:10 ( 12-hour clock).
or you can just add up :hr I min
7 : 30pm
+ 1 : 40
________

Given:
The vertices of the rectangle ABCD are A(0,1), B(2,4), C(6,0), D(4,-3).
To find:
The area of the rectangle.
Solution:
Distance formula:
[tex]D=\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}[/tex]
Using the distance formula, we get
[tex]AB=\sqrt{(2-0)^2+(4-1)^2}[/tex]
[tex]AB=\sqrt{(2)^2+(3)^2}[/tex]
[tex]AB=\sqrt{4+9}[/tex]
[tex]AB=\sqrt{13}[/tex]
Similarly,
[tex]BC=\sqrt{(6-2)^2+(0-4)^2}[/tex]
[tex]BC=\sqrt{(4)^2+(-4)^2}[/tex]
[tex]BC=\sqrt{16+16}[/tex]
[tex]BC=\sqrt{32}[/tex]
[tex]BC=4\sqrt{2}[/tex]
Now, the length of the rectangle is [tex]AB=\sqrt{13}[/tex] and the width of the rectangle is [tex]BC=4\sqrt{2}[/tex]. So, the area of the rectangle is:
[tex]A=length \times width[/tex]
[tex]A=\sqrt{13}\times 4\sqrt{2}[/tex]
[tex]A=4\sqrt{26}[/tex]
[tex]A\approx 20[/tex]
Therefore, the area of the rectangle is 20 square units.
Solve for the missing side. Round to the nearest tenth.

Which property of equality justifies the statement If MN + PQ = RS + PQ, then MN = RS?
Answer:
Additive Property of Equality
Step-by-step explanation:
If we are discussing equations, then the property would be the Additive Property of Equality. It states that if we know something is added to both sides of an equation, the sides remain equal. If y+x=z+x, we know that y=z.
Is 72 Inches greater less or equal to 2 yd and why
Answer:
72 is equal to 2 yards.
Explanation:
There are 36 inches in one yard.
(another way to look at this is there are 3 feet in one yard, each feet is 12 inches. So, 12 multiplied by 3 is equal to 36 inches, or one yard)
Then, since in this question we are finding out in relation to 2 yards, add 36 inches + 36 inches, and that is equal to 72 inches.
72 and 72 are equal :)

Alice tyre pressure gauge shows a reading which is 8% lower than actual pressure
what is the actual pressure of Alices tires when the gauge shows 33.58
Answer:
30.8936
Step-by-step explanation:
Pressure guage reading is 8% lower than tbe actual pressure.
Therefore, for a tyre with guage pressure, 33.58 ;
The actual pressure of tyre would be :
Guage pressure - 8% of guage pressure
33.58 - (0.08 * 33.58)
33.58 - 2.6864
= 30.8936
Actual pressure = 30.8936

Which graph represents a sequence that converges because the values approach 2?
Answer:
its b
Step-by-step explanation:
just did it on edge
Graph C represents a sequence that converges because the values approach 2.
What is a converging graph?Convergent definition in mathematics is a property (displayed by certain innumerable series and functions) of approaching a limit more and more explicitly as an argument (variable) of the function increases or decreases or as the number of terms of the series gets increased.
According to the given problem,
Graph 1, Graph 2 and Graph 4 are diverging graphs. We are assuming this because the a divergent sequence doesn't have a limit. Thus, this sequence converges to 0. In many cases, however, a sequence diverges that is, it fails to approach any real number.
Graph 3 has a limit and converges as it approaches 2.
Hence, we can conclude that Graph 3 converges because the values approach 2.

1. The area of a figure is 32 square centimeters.
Suppose the sides of the figure are doubled. What
will be the new area of the similar figure?
Answer:
128
Step-by-step explanation:
If the area of a figure is 32 square centimeters then the length/breadth could be 8cm and 4cm or 16cm and 2cm.
Let’s assume that the the sides of the figure are doubled, if that’s the case then we would arrive at 8*2 * 4*2 or 16*2 * 2*2 in which 16*8 or 32*4 which will both result to 128 as the answer.

Answer: 240.6cm *squared*
Step-by-step explanation:
Surface Area= (2 x Area of 1st face) + (2 x Area of 2nd face) + (2 x Area of 3rd face)
= (2 x 10.5cm x 5.4 cm) + (2 x 10.5 cm x 4.0cm) + (2 x 5.4cm x 4.0cm)
= 113.4cm*squared* + 84.0cm *squared* + 43.2cm *squared*
= 240.6cm *squared*
OR
= 2 x (sum of the 3 faces)
= 2 x (56.7cm * squared* + 42.0cm *squared* + 21.6cm *squared*)
= 2 x 120.3cm *squared*
= 240.6cm *squared*

HELP PLEASEEE
Answer:
15.48 yd squared
Step-by-step explanation:
This is because 6 yards can be used as the radius of your circle. square your radius, so 6x6 which is 36 then multiply by 3.14. You then get 113.04. Since it is a semicircle, divide it by 2. You now get 56.52. If you know your radius, you know your diameter which is 12. 12 is also the length of the rectangle so 6x12 is 72 which is the area of the rectangle. Now subtract 56.52 from 72 to get 15.48 which is the shaded region of the rectangle. So I believe that you are doing yards, so 15.48 yd squared. I hope this helps :)
