Answer:
1,290,000
Step-by-step explanation:
Answer:
1,290,000
Step-by-step explanation:
If we are rounding to the nearest thousand, then we are finding the number in the hundredth's and rounding it.
From 1-9 If it's less than 5, round down. If it's 5 or more, round up.
At this case, it is 8 in the hundredths and nine in the thousandths. Since 8 is 5 or greater, you round it up to 1000, but the thousandth's place has a nine, which nine plus 1 is 10.
Therefore, 1,289,845 rounded up is 1,290,000.

∠1 and ∠2 form a straight angle. ∠1 has a measure of 28°.
What is the measure of ∠2? PLZ HELP
Answer:
∠2 = 152
Step-by-step explanation:
A straight angle should always equal 180, and that is really the key to how we answer this problem. That means that ∠1 and ∠2 are supplementary, and add up to 180°.
That means that 180-28, will give us our other angle.
Answer:
152°
Step-by-step explanation:
Angles on a straight line add up to 180°
Angle 2 + 28 = 180
Angle 2 = 180 - 28
= 152°

Which volume could belong to a cube with a side length that is an integer? Recall the formula Cube volume = s cubed. 18 cubic inches 36 cubic inches 64 cubic inches 100 cubic inches
We have been given 4 choices. We are asked to choose the volume that could belong to a cube with a side length that is an integer.
We know that volume of a cube is cube of each side length.
To solve our given problem, we will take cube root of each given value. The cube root of which value will be an integer that will be our correct choice.
A. [tex]s^3=18[/tex]
[tex]\sqrt[3]{s^3}=\sqrt[3]{18}[/tex]
[tex]s=2.62074[/tex]
Since cube root of 18 is not an integer, therefore, 18 is not a correct choice.
B. [tex]s^3=36[/tex]
[tex]\sqrt[3]{s^3}=\sqrt[3]{36}[/tex]
[tex]s=3.301927[/tex]
Since cube root of 36 is not an integer, therefore, 36 is not a correct choice.
C. [tex]s^3=64[/tex]
[tex]\sqrt[3]{s^3}=\sqrt[3]{64}[/tex]
[tex]s=4[/tex]
Since cube root of 64 is 4 and 4 is an integer, therefore, 64 is the correct choice.
D. [tex]s^3=100[/tex]
[tex]\sqrt[3]{s^3}=\sqrt[3]{100}[/tex]
[tex]s=4.641588[/tex]
Since cube root of 100 is not an integer, therefore, 100 is not a correct choice.

Which line appears to have the same slope as the equation x-y=4 and has a y-intercept that is 2 units above the y-intercept of the given equation?
Answer:
B
Step-by-step explanation:
First, find the y-intercept form of the equation:
x - y = 4
x - x - y = 4 - x
-y = 4 - x
-y = -x + 4
-y/-1 = -x/-1 + 4/-1 (to get the y positive)
y = x - 4
The y-intercept is -4. This means that a y-intercept two units above 4 would be -2. Whichever line crosses the y axis at the value of -2 is the answer (line B)
hope this helps :)

Tom has a cube a rectangle prism and a triangular prism. Which of these shapes have more than 6 vertical?
The cube and rectangular prism.
Step-by-step explanation:
The triangular prism has 5 and the other two both have 8.
None of the shapes mentioned in the question, a cube, a rectangular prism, or a triangular prism, have more than six faces. For more complex shapes like Icosahedron, they do carry more than six faces.
Explanation:The student's question is about understanding which among the shapes - a cube, a rectangular prism, and a triangular prism - has more than six faces. To answer this, we should first understand that a cube and a rectangular prism (or cuboid) both have 6 faces and a triangular prism also has 5 faces only. Hence, none of these shapes deliver more than 6 faces as specified in the question. For a three-dimensional shape to have more than 6 faces, one has to move towards more complex shapes. For example, the provided reference suggests Icosahedron, a shape with 20 faces is an example of a shape with more than six faces.

The table shows the prices of 8 different treadmills at a sporting goods
store. This week the store is having a 50% off sale on all treadmills. What
are the mean, median, mode and range of the discounted prices?
$640 $810||$755 $810
$1175 $900 $1080 $530
mean: $736.25, median: $900; mode: $810; range: $645
mean: $837.50; median: $810; mode: $810; range: $645

mean: $418.75; median: $405; mode: $405; range: $322.50
The mean of the discounted prices is $736.25, the median is $810, the mode is $810, and the range is $645.
Explanation:To find the mean of the discounted prices, we add up all the prices and divide by the total number of prices. In this case, the mean is $736.25 because (640 + 810 + 755 + 810 + 1175 + 900 + 1080 + 530) / 8 = 736.25.
To find the median of the discounted prices, we arrange the prices in ascending order and find the middle value. Since there are 8 prices, the median is the average of the 4th and 5th values, which are $810 and $810, respectively. So, the median is $810.
To find the mode of the discounted prices, we look for the value that appears most frequently. In this case, $810 appears twice, which is more often than any other price. Therefore, the mode is $810.
To find the range of the discounted prices, we subtract the smallest price from the largest price. In this case, the range is $645 because $1175 - $530 = $645.

After simplifying the following rational expression, what is the leading coefficient in the NUMERATOR? [Recall: writing in Standard Form]
Answer:

Step-by-step explanation:
We are required to simplify the rational expression:
[tex]\dfrac{4}{x^2+4x-5} -\dfrac{5}{x^2-25}[/tex]
First, we factorize the denominators where possible
[tex]x^2+4x-5=x^2+5x-x-5=x(x+5)-1(x+5)=(x-1)(x+5)\\x^2-25=x^2-5^2 \\$Applying difference of two squares\\x^2-5^2=(x-5)(x+5)[/tex]
Therefore, our rational expression becomes:
[tex]\dfrac{4}{(x-1)(x+5)} -\dfrac{5}{(x-5)(x+5)}\\$Taking LCM\\=\dfrac{4(x-5)-5(x-1)}{(x-1)(x-5)(x+5)}\\=\dfrac{4x-20-5x+5}{(x-1)(x-5)(x+5)}\\=\dfrac{-x-15}{(x-1)(x-5)(x+5)}\\$Factoring out minus in the numerator and -(x-5)=(5-x)\ in the denominator\\=\dfrac{x+15}{(x-1)(5-x)(x+5)}[/tex]

Two lines defined by the equations $y = mx + 4$ and $y = 3x + b$, where $m$ and $b$ are constants, intersect at the point $(6, 10)$. What is the value of $b + m$?
Answer:
-7
Step-by-step explanation:
The two lines intersect at the point (6,10), so this point belongs to both lines. This means that if we use the value of x = 6 in the lines, we will find y = 10
So we can use this point to find the values of b and m:
y = mx + 4
10 = 6m + 4
6m = 6
m = 1
y = 3x + b
10 = 3*6 + b
b = 10 - 18 = -8
So the value of b + m is -8 + 1 = -7
After substituting the intersection point (6, 10) into both line equations and solving for m and b respectively, we find that the value of b + m is -7.
To find the value of b + m when two lines intersect at the point (6, 10), we can substitute the coordinates of the intersection point into both line equations. Since the coordinates (6, 10) must satisfy both equations, we have:
For the first equation y = mx + 4:
10 = m*6 + 4,
which simplifies to:
m = 1.
For the second equation y = 3x + b:
10 = 3*6 + b,
which simplifies to:
b = -8.
Having both values, we can now calculate b + m:
b + m = (-8) + 1 = -7.
The value of b + m is -7, which represents the sum of the y-intercept of the second line and the slope of the first line.

Use the order of operations to find the value of the expression.
12÷2*3-(7-5)
O A.0
O B.6
O C.16
O D.19
Answer:
C. 16
Step-by-step explanation:
12÷2×3−(7−5) = 16.
I hope this helps!
Following the order of operations (PEMDAS/BODMAS), the expression simplifies as:- 12 ÷ 2 * 3 - (7 - 5) = 6 * 3 - 2 = 18 - 2 = 16. So, the value is 16.
To find the value of the expression 12 ÷ 2 * 3 - (7 - 5), we need to follow the order of operations, often remembered using the acronym PEMDAS (or BODMAS):
1. Parentheses (or Brackets): First, we evaluate what's inside the parentheses. In this case, (7 - 5) equals 2.
2. Exponents (or Orders): There are no exponents or orders in this expression.
3. Multiplication and Division: After dealing with parentheses, we move from left to right. So, 12 ÷ 2 * 3 is calculated as follows:
12 ÷ 2 * 3 = 6 * 3 = 18
4. Addition and Subtraction: Again, we move from left to right. Now we subtract 2 (the result from step 1) from 18 (the result from step 3):
18 - 2 = 16
So, the final answer is 16.
In summary, using the order of operations, the expression simplifies to 16. It's crucial to follow these rules to ensure that mathematical expressions are evaluated correctly, as different orders can lead to different results.

Suppose you decided to keep flipping a coin until tails came up, at which
point you would stop. What is the probability of tails coming up on the 4th flip
of the coin? Round your answer to the nearest tenth of a percent.
A. 3.1%
B. 6.3%
C. 1.6%
D. 12.5%
Answer:
B. 6.3%
Step-by-step explanation:
For each time that the coin is tosse, there are only two possible outcomes. Either it comes up tails, or it does not. The probability of coming up tails on a toss is independent of any other toss. So we use the binomial probability distribution to solve this question.
Binomial probability distribution
The binomial probability is the probability of exactly x successes on n repeated trials, and X can only have two outcomes.
[tex]P(X = x) = C_{n,x}.p^{x}.(1-p)^{n-x}[/tex]
In which [tex]C_{n,x}[/tex] is the number of different combinations of x objects from a set of n elements, given by the following formula.
[tex]C_{n,x} = \frac{n!}{x!(n-x)!}[/tex]
And p is the probability of X happening.
Fair coin:
Equally as likely to come up heads or tails, so [tex]p = 0.5[/tex]
Probability that the first tails comes up on the 4th flip of the coin?
0 tails during the first three, which is P(X = 0) when n = 3.
Tails in the fourth, with probability 0.5. So
[tex]p = 0.5P(X = 0)[/tex]
[tex]P(X = x) = C_{n,x}.p^{x}.(1-p)^{n-x}[/tex]
[tex]p = 0.5P(X = 0) = 0.5*(C_{3,0}.(0.5)^{0}.(0.5)^{3}) = 0.0625[/tex]
