Fifty-four hundredths[tex]\\ \tt\hookrightarrow \dfrac{54}{100}[/tex]
More simplify
[tex]\\ \tt\hookrightarrow \dfrac{27}{50}[/tex]
Solution:
Since there is two digits on the right of the decimals, it is called "the hundredths."
=> 1 digit on the right of decimal - tenths=> 2 digits on the right of decimal - hundredths=> 3 digits on the right of decimal - thousandths=> 4 digits on the right of decimal - ten thousandthsNow, we can recite 0.54 as 54 hundredths. The word "54 hundredths" defines 54/100. Hence, Option A is correct.

In a pair of vertical angles one
angle measures 46° and the
other is (2x+7)º. Determine the
value of x.
Answer:
19.5
Step-by-step explanation:
We are given the pair of angles are vertical angles, meaning they are congruent or equal. We can use this to set up an equation to solve for x...
46=2x+7
Subtract 7 from both sides
39=2x
Divide both sides by 2
x=19.5

Answer:

Step-by-step explanation:
<3 and <2 are on a straight line.a straight line is 180° .so <3 +<2=180.angles which add up to 180 ° are said to be supplement
The best statement in geometric proof that proves the theorem that vertical angles are equal [tex]\angle2 + \angle3 = 180^{\circ}[/tex] because ∠2 and ∠3 are linear pair.
In the given proof, where the angles are labeled as ∠1, ∠2, ∠3, and ∠4, demonstrate the equality of vertical angles by utilizing the concept of a linear pair:
Step 1: Given two lines intersect.
Step2:
State that ∠1 and ∠2 are adjacent angles, as they share a common side.Introduce the concept of a linear pair, which states that if two angles form a straight line, their measures sum up to 180°. Since ∠1 and ∠2 form a straight line, their measures sum up to 180 degrees. Express the equation: [tex]\angle1 + \angle2 = 180^{\circ}[/tex].Step 3:
Demonstrate that ∠2 and ∠3 are also adjacent angles, sharing a common side.Apply the linear pair concept to ∠2 and ∠3, resulting in the equation: [tex]\angle2 + \angle3 = 180^{\circ}[/tex].Step 4:
By comparing the equations [tex]\angle1 + \angle2 = 180^{\circ}[/tex] and [tex]\angle2 + \angle3 = 180^{\circ}[/tex], deduce that ∠1 and ∠3 are equal angles.By following this step-by-step geometric proof, establish that the best statement to prove the theorem "Vertical angles are equal when two lines intersect" is the statement that defines vertical angles as "Vertical angles are formed by adjacent angles sharing a common side

A rectangular field is ten times as long as it is wide. If the perimeter of the field is 1540 feet, what are the dimensions of the field?
Answer:
700 by 70
Step-by-step explanation:
The equation for perimeter is 2(l + w). Since the length has an assigned value, l will become 10w.
2(10w + w) = 1540
First, add the parenthetical expression to get 11w.
2(11w) = 1540
Now, DISTRIBUTE! 2(11w) becomes 22w.
22w = 1540
Lastly, divide by 22 to get 70. You can also say that this could be 22w = 154 * 10. 22 * 7 is 154 (140 + 14), and 7 * 10 is 70.
w = 70
Now that we know the width, substitute 70 for w in the 10w expression.
l = 10(70)
Just multiply and you'll get 700.
l = 700
Now we know the dimensions to be 700 * 70 (or 70 * 700; I just prefer to put the length first)

A novelty store sells 8 comic books for every 3 action figures. On
Monday, they sold 32 comic books. On Tuesday, they sold 18 action
figures. What is the difference between the number of action
figures sold on Monday and Tuesday? Explain.
Answer:
Step-by-step explanation:
THE answer is 6
First Calculate the number of action figures sold on Monday:
8 comic books for every 3 action figures
32 comic books =? action figures
8 x 4 = 32
so, 3 x 4 = 12 action figures sold on Monday
next Find the difference between the number of action figures sold on Monday and Tuesday
They're asking for the difference, so you subtract
18 - 12 = 6
Hence, the difference in the number of books on Monday and Tuesday is 6

Dad caught 22 fish in the morning. He threw 5
back because they were too small. He caught 12
more in the afternoon. How many fish did dad
have then?
Is 29 the answer to this problem.
He caught 22 but put 5 back so had 22-5 = 17 fish
He then caught 12 more for a total of 17 + 12 = 29
Answer: 29 fish.
Answer:
The answer is 29 (so you were right!)
Step-by-step explanation:
He had 22 fish, and he threw 5 back
22 - 5 = 17
He caught 12 more in the afternoon
17 + 12 = 29

Can the sides of a triangle have lengths 4, 7, and 10?
yes
no
Answer:
i kinda like ixl but the answer is yes
Step-by-step explanation:
Yes these side lengths can make a triangle
The triangle side length rule states that any 2 sides of a triangle are greater than the other side.
Let's use this rule to determine if these side lengths can make a triangle.
4+7=11 and 11 is greater than 10.
4+10=14 and 14 is greater than 7.
7+10=17 and 17 is greater than 4.
These side lengths can make a triangle.
Normal Distribution (Standard deviation)
Image attached! Due in 1 hour! please help!
I don't know what kind of calculator you have at your disposal, so I'll just give one way of computing the sample mean and standard deviation.
• To get the mean, add up all the data points and divide the total by the number of data:
[tex]\bar x = \displaystyle \sum_i \frac{x_i}n = \frac{1243+1264+\cdots+1275}9 \approx 1273.89 \\ \implies \boxed{\bar x \approx 1274}[/tex]
• To get the s.d. s, first compute the variance s² by adding up the squared difference between each of the data points and the sample mean, and divide the total by 1 less than the number of data:
[tex]s^2 = \displaystyle \sum_i \frac{\left(x_i-\bar x\right)^2}{n-1} = \frac{(1243-1274)^2+(1264-1274)^2+\cdots+(1275-1274)^2}8 \approx 1211.61[/tex]
The s.d. is the square root of the variance:
[tex]s^2 \approx 1211.61 \implies s \approx 34.8082 \implies \boxed{s\approx 35}[/tex]
The 90% confidence interval for the sample mean has upper and lower limits, respectively, of
[tex]\bar x \pm \dfrac{\left|Z_{\alpha/2}\right| s}{\sqrt n}[/tex]
(positive root for upper limit, negative root for lower limit)
where [tex]Z_{\alpha/2}[/tex] is the critical value for a (1 - α)×100% confidence level. By critical value, I mean
[tex]\mathrm{Pr}\left[ Z \le Z_c \right] = c[/tex]
where Z is a random variable following the standard normal distribution.
In this case, we have a 90% confidence level, so α = 0.1, and the critical value is [tex]Z_{0.05} \approx -1.64[/tex]. Then the confidence interval has upper limit
[tex]\bar x + \dfrac{\left|Z_{0.05}\right|s}{\sqrt n} = 1274 + \dfrac{1.64 \times 35}{\sqrt9} \approx 1292.97 \approx \boxed{1293}[/tex]
and lower limit
[tex]\bar x - \dfrac{\left|Z_{0.05}\right|s}{\sqrt n} = 1274 - \dfrac{1.64 \times 35}{\sqrt9} \approx 1254.8 \approx \boxed{1255}[/tex]

Area of a rectangle - A=lw or area=length times width
Separate the shapes first, you would draw a line between the two if this was on paper.
Find the separate areas.
Rectangle area:
8*5=40
Triangle area:
find the height first. the height of this triangle is the same as the length of the rectangle minus the 1 and 2 cms.
8-1-2=5
1/2*5*5=12.5
Now add the areas:
40+12.5=52.5cm^2
