please help :) Which sentence is true? A. 9.46 times 10 to the 12 power > 4.0 times 10 to the 13 power B. 9.46 times 10 to the 12 power < 4.0 times 10 to the 13 power
Answer:
B
Step-by-step explanation:
The problem is simple because they use powers of 10. When something is multiplied by a power of ten, it is essentially moving the decimal point over for every power.
9.46x10^12= 9460000000000
4.0x10^13= 40000000000000
Although 4 itself is less than 9.46, since is is being multiplied by 10^13, it will be one decimal place bigger.
Micheal recorded the number of points his team scored for the first seven basketball games, 64,58,60,52,56,62,54 Which box plot correctly represents the data?
Answer:
The correct box plot is B (Bottom left)
Step-by-step explanation:
I have attached the appropriate picture containing the box plots to this answer. In order to choose the most appropriate box plot, we have to find the median of the distribution and locate the box plot showing the correct median. This is done as follows:
To find the median, we will first arrange the distribution in ascending (or descending) order
Median = 52, 54, 56, 58, 60, 62, 64
Next, we will group the data into two halves, and choose the middle term, which is 58. this becomes the median.
From the diagram, box plots, A, B and C have their median as 58, in order to determine the correct plot, we will find the medians to the lower and upper halves of the distribution. This is done as follows:
Lower half: 52, 54, 56, 58
Median of lower half = (54 + 56) ÷ 2 = 55
upper half = 58, 60, 62, 64
Median of upper half = (60 + 62) ÷ 2 = 61
From the picture the plot with these three medians from lower half to upper half (55, 58, 61) is plot B (bottom left)
Note the medians are the lines that form the boundaries and at the middle of the box.
Answer:
The answer is B bottom left :

You buy six T-bone steaks that cost $15.99 per pound. The weight that is listed on the package is 5.77 pounds. The scale that weighed the package is accurate to within 1 32 pound. How much per kilogram might you be undercharged or overcharged? (Round to the nearest cent.)
Answer:
Amount per kilogram, undercharged or overcharged is 0.50
Step-by-step explanation:
Given:
cost of T-bone steaks per pound = $ 15.99
weight listed on package = 5.77 lb
Accuracy of the scale = 1/32 lb
To find:
Amount undercharged or overcharged
Solution:
Let x represent the weight of the package.
Then compute the error in the weight
| x - 5.77 | < 1 / 32
This makes an absolute value inequality
If an inequality is given in the form | x | < a then solution is in the form:
–a < x < a.
If an inequality is in the form | x | > a, then solution splits in the form:
x < –a or x > a.
compute the amount undercharged or overcharged:
First multiply the above inequality by cost of T-bone steaks per pound
15.99 |x - 5.77| < 15.99 (1 / 32)
15.99 |x - 5.77| < 15.99(0.03125)
15.99 |x - 5.77| < 0.4996875
15.99 |x - 5.77| < 0.50
Hence the amount undercharged or overcharged is $0.50
Explain the Golden Rule for solving equations using an example. NEED HELP QUICK
Answer:
See explanation
Step-by-step explanation:
The golden rule for solving equations is to
A. Simplify each side of the equation by removing parentheses and combining like terms
B. Add/Subtract to isolate the term with the variable on one side
C. Use multiplication/division to isolate the variable
Let's assume we have the equation [tex]2x + 3x + (5\cdot2) = 35[/tex]
The first thing we need to do is solve inside the parentheses and combine like terms. 2x and 3x are like terms, so:
[tex]2x + 3x + 10 = 35\\\\5x + 10 = 35[/tex]
Now we have to subtract/add to isolate the term with the variable. To do this, we can subtract 10 from both sides.
[tex]5x + 10 - 10 = 35-10\\\\5x = 25[/tex]
Now we divide to isolate x.
[tex]5x \div 5 = 25\div5\\\\x = 5[/tex]

The length of a rectangle is 3cm longer than its width.If the perimeter of the rectangle is 54cm,find its length in cm.
Answer:
length = 15 cm
Width = 12 cm
Step-by-step explanation:
Let width = w cm
Length = w + 3
Perimeter of rectangle = 54 cm
2 * (length + width) = 54
2 * (w+3 + w) = 54 {Add like terms}
2 *(2w + 3) = 54
2*2w + 2 * 3 = 54
4w + 6 = 54
Subtract 6 form both sides
4w = 54 - 6
4w = 48
Divide both sides by 4
w = 48/4
w = 12 cm
Length = 12 + 3= 15 cm
Answer:
Length = 15cm
Step-by-step explanation:
let width be x
length = x+3
Perimeter = 2(l + b)
Perimeter = 54cm
equating:
2(x + x + 3) = 54
2(2x +3) = 54
4x + 6 = 54
4x = 54 - 6
4x = 48
x = 48/4 = 12
width = x = 12cm
length = x +3 = 12 + 3 = 15cm
change to a whole number or mixed number 12/7
Answer:
1 5/7
Step-by-step explanation:
[tex]\frac{12}{7} \\= 12\div 7 = 1\: remainder\: 5\\\\= 1 \frac{5}{7}[/tex]
Answer: 1 and 5/7
Step-by-step explanation: To write an improper fraction as a mixed number,
divide the denominator into the numerator.
So here, we have 7 divided into 12.
7 divides into 12 one time, 1 × 7 is 7, and 12 - 7 is 5.
So 7 divides into 12 one time with a remainder of 5.
So we have 1 whole and 5 out of 7 parts or 1 and 5/7.
So the improper fraction 12/7 can be written
as the mixed number 1 and 5/7.

Write the interval-25 < x < 30
using set notation and interval
notation.
Answer:
Set notation: { x ∈ ℝ | -25 < x < 30 }
Interval notation: (-25, 30)
Step-by-step explanation:
In set notation,
"x ∈ ℝ" means "x is an element of all real numbers"
you then write the restrictions after that, which would be "-25 < x < 30"
this gives you { x ∈ ℝ | -25 < x < 30 },
"x is an element of all real numbers, such that x is larger than -25 and less than 30"
In interval notation, it is written as (-25, 30). The parentheses mean that the interval does not include the numbers -25 or 30.
If the interval does include those numbers, i.e. if it was "-25 ≤ x ≤ 30" instead of "-25 < x < 30" you would use brackets instead of parentheses,
giving you {-25, 30}.

10 People fit comfortably in a 5 feet by 5 feet area. Use this value to estimate the size of a crowd that is 5 feet deep on both sides of the street along a 2-mile section of a parade route.
Answer:
The size of the crowd that is 5 feet deep on both sides of the street along a 2-mile section of a parade route is 42,240 people
Step-by-step explanation:
The number of people that can fit comfortably in a 5 feet by 5 feet area = 10
Therefore;
The ratio of the number of people per unit area = 10/(5 × 5) = 10/25
The area, A, occupied by the crowd = 5 feet × 2 mile × 2
2 miles = 10,560 feet
∴ A = 5 feet × 10,560 feet × 2 = 105,600 ft²
We then have;
[tex]\dfrac{Number \ of \ people}{105,600} =\dfrac{10}{25}[/tex]
[tex]Number \ of \ people = {105,600} \times \dfrac{10}{25} = 42,240 \ people[/tex]

The probability of a middle school student owning a skateboard is 0.58, of owning a bicycle is 0.48 and of owning both is 0.45. If a middle school student is chosen at random, what is the probability that the middle school student owns a skateboard or a bicycle?
Answer:
The probability that the middle school student owns a skateboard or a bicycle is 0.61.
Step-by-step explanation:
We are given that the probability of a middle school student owning a skateboard is 0.58, of owning a bicycle is 0.48, and owning both is 0.45.
A middle school student is chosen at random.
Let the probability of student owning a skateboard = P(S) = 0.58
The probability of student owning a bicycle = P(B) = 0.48
The probability of student owning both = P(S [tex]\bigcap[/tex] B) = 0.45
Now, the probability that the middle school student owns a skateboard or a bicycle is given by = P(S [tex]\bigcup[/tex] B)
P(S [tex]\bigcup[/tex] B) = P(S) + P(B) - P(S [tex]\bigcap[/tex] B)
= 0.58 + 0.48 - 0.45
= 0.61
Hence, the probability that the middle school student owns a skateboard or a bicycle is 0.61.

find the area of the 1/4 circle when the radius is 8
Answer:
Method 1 (using the area of a whole circle and dividing by 4)
First work out the area of the whole circle by substituting the radius of 8cm into the formula for the area of the circle:
A = π ×r²
= π ×8²
= 64π (leave the answer as an exact solution as this need to be divided by 4).
So all you need to do now is divide the answer by 4:
Area of a quadrant = 64π ÷4 = 16π = 50.3 cm² to 3 significant figures.
Method 2 (using ¼ πr²)
Substitute r = 8 directly into the formula A = ¼ πr².
A = ¼ πr².
A = ¼ × π × 8².
A = 50.3 cm²
As you can see it gives exactly the same answer as method 1.
Answer:
64pi / 4 = 16pi, or 50.27
Step-by-step explanation:
We use the area formula:
π * r^2 = Area
Substitute in 8 for r to get 64pi
Then all you have to do is divide 64pi by 4 to find a quarter of the area of the circle, which is 16pi. Or if you want rounded to nearest tenth, 50.27

The external angle of a triangle is equal to the sum of the 2 opposite interior angles.
7x - 3 is an exterior angle of the triangle, thus
7x - 3 = 4x - 2 + 41
7x - 3 = 4x + 39 ( subtract 4x from both sides )
3x - 3 = 39 ( add 3 to both sides )
3x = 42 ( divide both sides by 3 )
