Answer:
B. 4m
Step-by-step explanation:
What you do is you just take the 8 and put it into the m.
m-8, 8-8=0 so A isn't your answer.
4m, 4(8)=32 so B is your answer.
B. 4m is your answer.
The expression 4m will give 32 at m=8 the correct option is B.
Expression in maths is defined as the collection of the numbers variables and functions by using signs like addition, subtraction, multiplication and division.

Answer:
Step-by-step explanation:
2.
Step where it was wrong ->
x-8 = 0
x=-8
They just put negative eight on the right side you have to cancel negative 8 out by adding negative 8 on both sides.
x-8=0
+8 +8
x=8 <- Right solution.

Step where it was wrong ->
8(p-7) = 75

Distributive Property you have to do 8 times p and 8 times -7, they just did 8 times p and forgot to do 8 times -7.

At the beach, 45% of people have red towels and 15% have blue towels. If the
rest have white, what percentage of the people at the beach have white
towels?
To find out what percent of the people at the beach have white towels, we can take the sum of the percents and subtract them from 100. In other words, we can add up the percents of both the red and the blue towels and subtract the sum from 100%.
45 + 15 = 60
100 - 60 = 40
Therefore, 40% of the people at the beach have a white towel.
Answer:
40%
Step-by-step explanation:
At the beach, 45% of people have red towels and 15% have blue towels. If the rest have white, 40% of the people at the beach have white towels.
In order to find the answer, you have to do the following steps:
45% + 15% = 60%
100% - 60% = 40%
Therefore, the answer is 40%.

Nine is less than a number is no more than 8 and no less than 3
Answer:
3 <= x <= 8
Step-by-step explanation:
A number is denoted as an arbitrary variable, let's call it x.
We have a double inequality:
1. No more than 8 means less than or equal to 8
2. No less than 3 means greater than or equal to 3
3 <= x <= 8
Answer:

Answer:
8052600
Step-by-step explanation:
According to the Order of Operations, in this case, you deal with all multiplication before adding everything up.
I am joyous to assist you anytime.
the expression 8 x 1,000,000 + 5 x 10,000 + 2 x 1,000 + 6 x 100 in standard form is equal to 8,052,600.
To express the expression 8 x 1,000,000 + 5 x 10,000 + 2 x 1,000 + 6 x 100 in standard form, we can simplify the multiplication and then sum up the products.
8 x 1,000,000 = 8,000,000
5 x 10,000 = 50,000
2 x 1,000 = 2,000
6 x 100 = 600
Adding these values together:
8,000,000 + 50,000 + 2,000 + 600 = 8,052,600
Therefore, the expression 8 x 1,000,000 + 5 x 10,000 + 2 x 1,000 + 6 x 100 in standard form is equal to 8,052,600.

sinθ> cosθ<0 where does angle θ lie
Since you want a negative cosine, your angle will surely lie in the II or III quadrant.
In particular, in the II quadrant, the cosine is negative and the sine is positive, so you surely have [tex]\sin(\theta)>\cos(\theta)[/tex]
As for the third quadrant, we start with
[tex]\sin(\pi)=0,\quad\cos(\pi)=-1[/tex]
(which implies that the sine is greater than the cosine) and we end with
[tex]\sin\left(\dfrac{3\pi}{2}\right)=-1,\quad\cos\left(\dfrac{3\pi}{2}\right)=0[/tex]
which implies that the sine is less than the cosine.
Halfway through, we have
[tex]\sin\left(\dfrac{5\pi}{4}\right)=\cos\left(\dfrac{5\pi}{4}\right)=\dfrac{\sqrt{2}}{2}[/tex]
So, only the first half of the III quadrant is fine, because sine and cosine are both negative, but the sine is "less negative" than the cosine, so we have, as requested,
[tex]\begin{cases}\sin(\theta)>\cos(\theta)\\\cos(\theta)<0\end{cases}[/tex]
So, the final answer is that the angle lies in the interval
[tex]\dfrac{\pi}{2}<\theta<\dfrac{5\pi}{4}[/tex]
Answer:
[tex]\theta\in\left(\pi+2k\pi;\ \dfrac{3\pi}{4}+2k\pi\right)[/tex]
Step-by-step explanation:
I think correct inequality is
[tex]\cos\theta<\sin\theta<0[/tex]
The easiest way is to draw graphs of sine and cosine functions in one coordinate system and read a set of solutions from the graph (look at the picture).
We need to solve the equation
[tex]\sin\theta=\cos\theta[/tex]
to get the intersection points of the graphs.
[tex]\sin\theta=\cos\theta\qquad\text{divide both sides by}\ \cos\theta\neq0\\\\\dfrac{\sin\theta}{\cos\theta}=1\to\tan\theta=1\to\theta=\dfrac{\pi}{4}+k\pi,\ k\in\mathbb{Z}[/tex]
We look at where the sine function graph is above the cosine function graph.

Match equation to its solution
Answer:
X= -5
Step-by-step explanation:
You must move all constants to one side of the equation (one side of the equal sign) and away from 2x. To do so, you must do the inverse operation, which would be subtraction in this case because 3 is a positive number. (Inverse of addition is subtraction, Inverse of subtraction is addition, Inverse of multiplication is division, and inverse of division is multiplication) If you squish a constant and variable together (2x) it means multiplication.What you must do to one side, you must do to the other. So, since you subtracted 3 from the 3, you must subtract 3 from -7, too(subtracting from a negative is just addition- but you keep the negative sign). Once this is done, your equation will be 2x=-10 Now, you must do the inverse operation to 2x to separate the 2. The inverse operation will be division. So, you divide both sides by 2. 2x divided by 2 will give you x. -10 divided by 2 will give you -5. (When you divided negative and positive numbers, the signs are different, meaning it's negative. If they had the same sign, it would be positive.)Therefore, your answer is x= -5Hope I helped! :)

0. Kevin needs to buy shrubs for his yard. Six shrubs at the nursery cost $72.00. At the garden
store, 6 shrubs cost $66.00. How much will be save if he buys 21 shrubs from the garden store
compared to if he had bought them at the nursery?
$12.00
6 Shows
67ttoo
By calculating the cost per shrub at both the nursery and the garden store, then multiplying by 21 shrubs, we find that Kevin saves $21.00 by purchasing from the garden store instead of the nursery.
Explanation:Kevin is trying to decide between two stores to purchase a total of 21 shrubs for his yard. In order to calculate how much money Kevin can save by choosing the garden store over the nursery, we will need to determine the cost per shrub at each location and then multiply by the total number of shrubs Kevin wants to purchase.
At the nursery, six shrubs cost $72.00, which means each shrub costs $72.00 ÷ 6 = $12.00.
For 21 shrubs, the cost at the nursery would be 21 × $12.00 = $252.00.
At the garden store, six shrubs cost $66.00, which gives us a cost of $66.00 ÷ 6 = $11.00 per shrub.
Therefore, for 21 shrubs, the total cost would be 21 × $11.00 = $231.00.
Now, let's find out the savings if Kevin buys from the garden store instead of the nursery: $252.00 - $231.00 = $21.00.
Thus, Kevin will save $21.00 by purchasing the shrubs from the garden store.

Answer:
0.007%
Step-by-step explanation:
This is the answer because I need points to answer a question
Answer:
99.9468 %
Step-by-step explanation:
The total percentage of the diamond and gold is:
0.0042 % + 0.049% = 0.0532%
The percentage of other metal that is neither gold or diamond = 100 - 0.0532
= 99.9468 %
I really don't get the whole Mean, Median and Mode thing.
Answer:
The mean is the average you're used to, where you add up all the numbers and then divide by the number of numbers. The median is the middle value in the list of numbers. The mode is the value that occurs most often.
Mean is all the numbers together in total so in order to get the mean you just add up all the numbers then divide by the total amount of numbers in that set.
Median in order to find the median you rearrange the numbers least from greatest and find the average from the two numbers in the middle of the set 2,2,2,2,2,4,5,5 21, in this case 2 because it's the number in the middle.
Mode in a set of numbers the mode is the most occurring of numbers 2,2,2,4,5,21,2 2,5 which would be 2 in this case.

39X5=5X(____-1)=(5X___)-(5X1)=___-___=__
Answer:
8 85
Step-by-step explanation:
The operational value being sought in the equation 39X5 equals 5X(___-1) is 40. When you multiply 5 with 40 and subtract the product of 5 and 1 from the result, you get 195, which matches 39x5.
Explanation:The equation provided is a multiplication and subtraction problem, where you're tasked to find a sequence of operations that gets from 39x5 to an answer. Detangle it step by step:
The first operation is simple multiplication: 39x5 equals 195.Then we need to figure out the number which when multiplied by 5 and subtracted by the product of 5 and 1 results in 195. This number is 40 because 5x40 is 200, and subtracting 5 (which is 5x1) gives us 195. Hence the equation becomes 5x(40-1). To verify, the left side of the equation 5x(40-1) becomes (5x40) - (5x1) which equals 200 - 5, and that is indeed 195, matching the right side of the first equation (39x5).Learn more about Multi-step equations here:https://brainly.com/question/18686312
