What is coordinate?Coordinates are a pair of numbers which are used to determine the position of a point or a shape in a 2-dimensional plane. We define the position of a point on a 2D plane using two numbers, called the x-coordinate and the y-coordinate.
here, we have,
given that,
Steve and Herb are choosing seats at the baseball stadium.
The seats are numbers like a coordinate grid. Steve chooses the seat at (1, 2).
If Herb does not want to sit in the same vertical or horizontal row as Steve's seat.
now, we have,
in the same vertical or horizontal row means The x value should not contain the number 1, and, the y value should not contain the number 2 .
now, we get,
The x value should not contain the number 1, so we can eliminate choice c,
the y value should not contain the number 2 so we can Eliminate option A and D.
The only we one we have not eliminated is B,
and it follows the rules of not having 1 in the x value or 2 in the y value.
Therefore the answer is option B.
Hence, The solution is: B) (0,1) is the seat should he choose.

We're not quite sure what the question is.
It appears you may be interested in the names of the groups of 3 digits. Each such group is called a "period." Each period is named for the place value of its right-most digit.
The period just to the left of the decimal point is the "ones" period. To the left of that is the "thousands" period, and to its left is the "millions" period.
When writing the name of a number, the name of the three digits within a period is given, followed by the period name (if it is greater than "ones"). This continues left to right, until you get to the decimal point. For example, the number shown is ...

It's easiest to reduce each statement to its simplest form for comparison
Our test statement can be reduced by combining like terms
16x - 12 -24x + 4 = -8x - 8
this becomes our new gold standard
a) 4 + 16x - 12(1 + 2x)
apply the distributive property by multiplying terms in parenthesis by -12
4 + 16x - 12 - 24x
combine terms
-8x - 8 Yeaah, We have a winner as it exactly matches our gold standard.
b) 40x - 16 is already in simplest terms and does NOT match the gold standard.
c) 16x - 24x - 4 + 12
has the same cardinal values as the original, but differing signs, reducing gives -8x + 8
Not quite the same as a plus sign occurs where a negative exists in our gold standard.
d) -8x - 8 is already in simplest terms and exactly matches our gold standard. Yeah!
e) 10(1.6x - 1.2 - 2.4x + 4)
apply distributive property by multiplying each term in parenthesis by 10
16x - 12 - 24x + 40
combine like terms
-8x + 28 does NOT match our gold standard

Sqrt8 (Sqrt2 - x) = 11
Answer:[tex]\frac{-7\sqrt{2} }{4}[/tex]
Step-by-step explanation:
So first, let's get rid of the parentheses. We can multiply it out to get [tex]\sqrt{16}-x\sqrt{8} =11[/tex]. We know that the square root of 16 is ±4, so now our equation is ±4 - [tex]x\sqrt{8}[/tex]=11. I'm guessing since the problem only has one solution it's most likely only positive 4, so let's revise our equation to 4 - [tex]x\sqrt{8}[/tex]=11. We can use inverse operations to make the a little easier to solve: -7= [tex]x\sqrt{8}[/tex]. We divide both sides by [tex]\sqrt{8}[/tex] to get [tex]\frac{-7}{\sqrt{8} } =x[/tex], which we can rationalize (remove the square root from the denominator so that it's a proper answer) by multiplying by [tex]\frac{\sqrt{8} }{\sqrt{8} }[/tex] (which is equal to one so we can use it) which is equal to [tex]\frac{-7\sqrt{8} }{8}[/tex]. Let's finish this by simplifying it. [tex]\sqrt{8} =2\sqrt{2}[/tex] (2x[tex]2^{2}[/tex]). We can simplify it further by simplifying the 2, making it [tex]\frac{-7\sqrt{2} }{4}[/tex].
Hope this wasn't too confusing! I'll answer any questions.
Answer:
x = -7 sqrt(2)/4
Step-by-step explanation:
Sqrt8 (Sqrt2 - x) = 11
Simplify sqrt(8) = sqrt(4*2) = 2 sqrt(2)
2 sqrt(2) (Sqrt2 - x) = 11
Distribute
2 *2 - 2 sqrt(2) x = 11
4 - 2 sqrt(2)x = 11
Subtract 4 from each side
4-2sqrt(2)x -4 = 11-4
-2 sqrt(2)x = 7
Divide each side by -2 sqrt(2)
-2 sqrt(2)x /-2 sqrt(2) = 7/ -2 sqrt(2)
x = - 7/ 2 sqrt(2)
Multiply top and bottom by sqrt(2)
x = - 7/ 2 sqrt(2) * sqrt(2)/ sqrt(2)
x = -7 sqrt(2)/4

A baseball player's batting average is equal to the number of hits divided by the number of at-bats.
[tex]\frac{hits}{at-bats}[/tex]
A professional player had 123 hits and 501 at-bats in 2010. In 2011, he had 131 hits and 515 at-bats. How many more consecutive hits would he have needed in order to raise his 2010 batting average to that of 2011?
he would need about 5 more hits to make his average equal to that in 2021
128/501 = .255
The player needs 5 consecutive hits in order to raise his 2010 batting average to that of 2011.
What is average ?An average of a list of data is the expression of the central value of a set of data. It is also defined as the ratio of summation of all the data to the number of units present in the list.
How to find the number of hits in order to raise the batting average ?It is given that a professional player had 123 hits and 501 at-bats in 2010 and in 2011, he had 131 hits and 515 at-bats.
Also, the baseball player's batting average is equal to the number of hits divided by the number of at-bats.
Average in 2010 - 123/501 = 0.245 .
Average in 2011 - 131/515 = 0.254 .
Thus if he increases the number of shots to 5 then we have the total number of shots as 123 + 5 = 128 .
Therefore the batting average for 2010 becomes - 128/501 = 0.255 which matches the batting average of 2011.
Thus, the player needs 5 consecutive hits in order to raise his 2010 batting average to that of 2011.

Andrea's Sequoia gets 12 miles per gallon while driving in the city, and 20 miles per gallon while on the highway. The last time she filled up the car it took 16 gallons of gas, and she had driven 280 miles since the previous fill-up. How many miles of that 280 were city driving?
Answer:
60miles
Step-by-step explanation:
if they drove x miles in the city and y miles on the highway then you know that
x + y = 280
x/12 + y/20 = 16
x + 12y/20 = 16*12 = 192
8y/20 = 88
y = 220
x = 280-y = 280-220 = 60

Answer:
A. [tex]y=4x-5[/tex]
Step-by-step explanation:
The equations are in slope-intercept form, which is written as y=mx+b. Where m is the slope and b is the y-intercept. So, first, find the slope. The line increases by 4 every unit; this means the slope is 4. Then, find the y-intercept. The y-intercept is where the line crosses the y-axis. Since the line crosses at -5, that is the b value. Therefore, the final answer is y=4x-5.

A stegosaurus eats ten twelfths of a plant and then eats two twelfths of the plant later. Estimate how much of the plant the dinosaur ate in all. Explain your thinking.
Answer:
12 Twelfths (12/10)
Step-by-step explanation:
If the dinosaur ate 10 twelfths, then ate 2 twelfths, you need too add that up.
10/12 + 2/12 = 12/10.
The dinosaur ate 12/10 of a plant. (6/5 if needed to simplify)
Hope this helps!
Answer:
0/12
Step-by-step explanation:
The answer is 0/12. We know this because if there are twelve twelfths [12/12] of a plant and the stegosaurus eats ten twelfths [10/12] of a plant then it is 12 - 10 or the fraction form [12/12 - 10/12] then we subtract and we get the answer [2/12]. And then later it says the stegosaurus ate two twelfths [2/12] of a plant then we subtract 2 - 12 or [2/12 - 2/12] that would then equal 0/12.

Answer:
10^9
Step-by-step explanation:
1,000,000,000

1 *10^9
We can drop the 1 because 1 times anything itself
10^9
Answer:
10^9 meters.
Step-by-step explanation:
A small trick I use is counting how many zeroes trail behind the one.
If we count the number of zeroes behind the one, there are 9.
Therefore 1,000,000,000 = 10^9 meters.
This can be proved by taking a number, say 1. If you multiply that by 10, you add a zero to the end of it.
To prepare for the town's race, Andrew runs around a rectangular field. The dimensions of the field are 450 feet
by 225 feet. How many times must Andrew run around the field in order to run 12 miles? One mile is 5,280
fect.
Round the answer to one decimal place if necessary?
Answer:
46.9 times
Step-by-step explanation:
First, we can calculate how many feet it takes to run around the field. To find the perimeter of a rectangle, we can use the formula
2* length + 2 * width. With the length being 450 and the width being 225 here, we can say that
2*450 + 2 * 225 = 1350 feet
Therefore, Andrew runs 1350 feet each time he runs around the field. Next, we need to figure out how much 1350 feet goes into 12 miles as we want to find how many times Andrew runs around the field to get to 12 miles. This can be represented by
12 miles/1350 feet
One thing that we can do here is multiply the fraction by 1 to keep it the same. Because 1 mile = 5280 feet, we can say that
1 mile/5280 feet = 1 = 5280 feet/1 mile. Therefore, it would be safe to multiply
12 miles/1350 feet by 1 = 5280 feet/1 mile. Note that feet is on the bottom in the first fraction (12 miles/1350 feet) and on the top in the second (5280 feet/1 mile) so they will cancel out. Similarly, miles are on top in the first and bottom in the second. We then have
12 miles/1350 feet * 5280 feet/1 mile =63360/1350 ≈ 46.9
