Thomas buys a cardboard sheet that is 8 by 12 inches. Let x be the side length of each cutout. Using complete sentences, explain the connection between the cutout and the volume of the box.
Answer: V = (12in - 2*x)*(8 in - 2*x)*x
Step-by-step explanation:
So we have a rectangular cardboard sheet, and we cut four squares of side length x in each corner so we can make a box.
Remember that for a box of length L, width W and height H, the volume is:
V = L*W*H
In this case, the length initially is 12 inches, but we remove (from each end) x inches of the length, then the length of the box will be:
L = 12 in - 2*x
For the width we have a similar case:
W = 8in - 2*x
And te height of the box will be equal to x, then:
H = x
This means that the volume is:
V = (12in - 2*x)*(8 in - 2*x)*x
Here we can see the connection between the cutout and the volume of the box

One week, seventy-two percent of the animals that came to a veterinary hospital were dogs. If there were 230 animals total, how many were dogs?
Answer:
166 dogs were at the veterinary hospital
Step-by-step explanation:
Here, we want to know the number of dogs that were at the veterinary hospital
From the question, 72% of these animals are dogs
72% of a total of 230
Mathematically, the number of dogs are as follows;
dogs = 72% of 230
dogs = 72/100 * 230 = 165.6
since we cannot have a fractional dog, we round off to the nearest whole number which is 166 dogs

-3 2^x + 3 = 2^(-3) + 3 = 0.125 + 3 = 3.125 (-3, 3.125)
-2 2^x + 3 = 2^(-2) + 3 = 0.25 + 3 = 3.25 (-2, 3.25)
-1 2^x + 3 = 2^(-1) + 3 = 0.5 + 3 = 3.5 (-1, 3.5)
0 2^x + 3 = 2^(0) + 3 = 1 + 3 = 4 (0, 4)
1 2^x + 3 = 2^(1) + 3 = 2 + 3 = 5 (1, 5)
2 2^x + 3 = 2^(2) + 3 = 4 + 3 = 12 (2, 12)
3 2^x + 3 = 2^(3) + 3 = 8 + 3 = 11 (3, 11)

You and your friend are standing back-to-back. Your friend runs 10 feet forward and then 8 feet right. At the same time, you run 11 feet forward and then 12 feet right. You stop and throw a baseball to your friend, who catches it. How far did you throw the baseball?
Answer:
29 feet
Imagine you are on an open plane.
you walk 11 feet forward and your friend 10 feet. you are now 21 feet apart. now put imaginary walls that stopped both of you at that 21 feet.
now, you go 12 feet to your right, and your friend 8 feet to their right. imagine you are pushing a wall in front of you.
at that point the side walls are 20 feet apart.
you and your friend are at opposite corners of a 20 by 21 foot room.
at that point it's just a matter if applying the Pythagorium theory.

Find the length of arc PS. Use 3.14 for pi Round to the nearest tenth. 6.48 in 739 1500 650 R
Answer:
8.3
Step-by-step explanation:
To find a length, we want to find how many radians our arc length is. Let's convert our 73-degree angle into radians, which will give us our radian length.
(73)≈1.2741
Now, we know our arc length is equal to about 1.2741 radians. Let's multiply this by our radius.
1.2741(6.48)≈8.3
Therefore, our arc length is about 8.3 inches.
I hope this helps!

Step-by-step explanation:
Javier and Carlita are studying measures of spread. After looking at Dot Plot A and Dot Plot B, Carlita believes the standard deviation for Dot Plot A is larger than the standard deviation for Dot Plot B. Javier believes the standard deviation for Dot Plot B is larger than the standard deviation for Dot Plot A. Choose whether Javier or Carlita is correct, and the best reasoning to support your answer.
Answer:
the answer is d
Step-by-step explanation:
a standard deliation is how streaded out the number thing is
Answer:
Carlita is correct because Dot Plot A is more spread out than Dot Pot B
Step-by-step explanation:
Dot Plot B is skewed left which means most of its data is on the left side so it will mostly have lower numbers as data. On the other hand, Dot Plot A is spread out so it has both low numbers but also some higher numbers.
Samuel invests £45 500 in an account that pays 4.5% compound interest per annum for the five years, then 3.5% . Work out how much money Samuel will have in his account in 13 years.
Answer:
$74,664.76
Step-by-step explanation:
We are to determine the future value of £45 500
The formula for calculating future value:
FV = P (1 + r)^n
FV = Future value
P = Present value
R = interest rate
N = number of years
Future value for the first 5 years = £45 500 x (1 + 0.045)^5 = $56,701.28
Future value for the remaining 8 years = $56,701.28 x ( 1 + 0.035)^8 = $74,664.76

B. 54 miles
C. 346.5 miles
D. 292.5 miles

27 miles for 2 hours so u add 27 + 27 = 54 than it says 65 miles per hour and travels for 4.5 hours so do 65 x 4.5 = 292.5 than add 54+292.6 and you will get the final answer wich is 346.5
If two lines are parallel, then
corresponding angles are congruent. i
Answer: Choice B)
If corresponding angles are not congruent, then the lines are not parallel.
==================================================
Explanation:
The given conditional is in the form "If P, then Q"
where,
P = two lines are parallelQ = corresponding angles are congruentThe P and Q are placeholders for those definitions shown above. So we'll simply do a "search and replace" to replace P and Q with those phrases. We do this shortening so that we can do logical operations.
Specifically, we'll do two things:
Swap the positions of P and QPlace a "not" before each letter after the swapWe go from the format "if P, then Q" to "if not Q, then not P". Those two formats are equivalent in truth value. This is known as the contrapositive.
In terms of the problem at hand, the phrase "if not Q, then not P" becomes "If corresponding angles are not congruent, then the lines are not parallel"
-------------
In short, we swap each part of the original "if ..., then ..." statement, and stick "not"s in there to negate each piece.
Option B is correct, if corresponding angles are not congruent then the lines are not parallel.
What is Mathematical Reasoning?In mathematics, reasoning involves drawing logical conclusions based on evidence or stated assumptions
The given statement is "If two lines are parallel, then corresponding angles are congruent."
Let us consider p as two lines are parallel,
q as corresponding angles are congruent.
If p is true then q should be true
or else if p is false then q also should be false
if P, then Q" to "if not Q, then not P". Those two formats are equivalent in truth value
This is known as the contrapositive.
"If two lines are parallel, then corresponding angles are congruent." is equivalent to if corresponding angles are not congruent then the lines are not parallel.
Hence, option B is correct, if corresponding angles are not congruent then the lines are not parallel.
