What is the distance between points (10,7) and (2,7) on a coordinate plane?
please help me
The distance between points (10,7) and (2,7) on a coordinate plane will be 8 units.
What is a distance formula?It is defined as the formula for finding the distance between two points. It has given the shortest path distance between two points.
The distance formula can be given as:
[tex]\rm d=\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}[/tex]
It is given that, the points on the coordinate planes are (10,7) and (2,7).
(x₁,y₁) = (10,7)
(x₂,y₂) = (2,7)
The distance between points (10,7) and (2,7) on a coordinate plane is found as,
(d) = √(x₂ - x₁)² + (y₂-y₁)²
Substitute the given values as,
(d) = √(2 - 10)² + (7 - 7)²
=√(-8)² + (0)²
=√64
=8 units
Thus, the distance between points (10,7) and (2,7) on a coordinate plane will be 8 units.

31.68 is 45% of what number?
Answer: The required number is 70.4.
Step-by-step explanation: We are given to find the number of which 31.68 is 45%.
Let x be the required number.
Then, according to the given information, we have
[tex]45\%\times x=31.68\\\\\Rightarrow \dfrac{45}{100}\times x=31.68\\\\\Rightarrow x=\dfrac{3168}{45}\\\\\Rightarrow x=70.4.[/tex]
Thus, the required number is 70.4.

Celina can walk 4 miles in 1 hour and can run 8 miles in 1 hour. What percent of Celina’s average running speed is her average walking speed? A. 25% B. 50% C. 75% D. 100%
There are different kind of speed in mathematics like average speed, instantaneous peed, to solve this question we need to know the concept of average speed. Therefore the correct option is option B
What is average speed?
Average speed is defined as the total sum of distance divided by total sum of time
Mathematically,
Average speed = total distance ÷total time taken
Here we have to find the percent of of Celina’s average running speed
So for this we will apply formula as
(Difference in distance ÷original distance)×100
So from question, Celina walk 4 miles in 1 hour and can run 8 miles in 1 hour so, the the difference in distance between running and walking is 8-4= 4
So to find the percent of Celina’s average running speed is her average walking speed = (4 ÷8)=50%
Therefore, Celina’s average running speed is her average walking speed is 50%. The correct option is Option B

1520 divided by 83 with remainder
To find 1520 divided by 83 with the remainder, divide 1520 by 83, which results in 18 with a remainder of 26.
The question from the student involves dividing 1520 by 83 and finding the remainder. To perform this calculation, we divide 1520 by 83. The quotient is the whole number result of the division, and the remainder is what is left over after the division.
Here's how you'd calculate it:
Divide 1520 by 83.
Find the whole number quotient, which is the number of times 83 goes into 1520 completely.
Calculate the remainder by subtracting the product of the quotient and 83 from 1520.
In this case, 1520 \\div 83 is 18 with a remainder of 14, since 83 x 18 = 1494, and 1520 - 1494 = 26. Therefore, 1520 divided by 83 equals 18 with a remainder of 26.

An elephant can run 1/4 of a mile in 36 seconds. At this rate, which expression can be used to determine how fast an elephant runs in miles per hour?
Answer: 25 miles per hour
Step-by-step explanation: Since elephant run 1/4 miles in 36 sec
that means in 1 sec elephant runs 1/(4×36) miles
and 1 hour=60×60 sec
that means in 1 hour elephant runs (60×60)/(4×36) miles=25 miles
i.e. elephant runs 25 miles per hour

what is the solution to the system of equations ?
(-1,8)
(8,-1)
(5,1/2)
(1/2,5)
Answer: The solution of the system of the equation is, (8,-1)
Step-by-step explanation:
Using substitution method
[tex]2x+4y=12[/tex] .......... (1)
[tex]y=\frac{1}{4}x-3[/tex] ......... (2)
Now we are putting equation (2) into equation (1), we get the value of 'x'
[tex]2x+4(\frac{1}{4}x-3)=12[/tex]
[tex]2x+\frac{4}{4}x-4\times 3=12[/tex]
[tex]2x-x=12+12[/tex]
[tex]3x=24[/tex]
[tex]x=8[/tex]
Now put the value of 'x' in equation (2), we get the value of 'y'
[tex]y=\frac{1}{4}x-3[/tex]
[tex]y=\frac{1}{4}\times 8-3[/tex]
[tex]y=2-3[/tex]
[tex]y=-1[/tex]
Hence, the correct option is, (8,-1)
The solution to the system of equations is (-1, 8).
Explanation:The given system of equations is:
2x + 4y = 12
y = ⅓x - 3
To find the solution to the system, we can solve it by substitution or elimination method:
Substitution Method:
From the second equation, we have y = ⅓x - 3.Substitute this value of y in the first equation.Replace y with ⅓x - 3 in the first equation: 2x + 4(⅓x - 3) = 12.Distribute 4 to both terms inside the parentheses: 2x + ⅓*4x - 12 = 12.Combine like terms: 2x + ⅓*4x = 12 + 12.Combine like terms: 2x + ⅓*4x = 24.Simplify: 2x + 4/4*x = 24.Simplify: 2x + x = 24.Combine like terms: 3x = 24.Divide both sides by 3 to solve for x: x = 8.Substitute the value of x in the second equation to find y: y = ⅓(8) - 3 = 2 - 3 = -1.Therefore, the solution to the system of equations is (-1, 8).

A farmer grows two types of grain in his fields. He has a seed budget of $18,000.00 and has spent $8,100.00 to plant wheat seed so far. If barley seed costs $47.00 per acre to plant, what is the maximum number of acres of barley the farmer can plant and still be under budget?
Answer: There is 211 number of acres of barley the farmer can plant and still be under budget.
hgfhfhfghfgh
Step-by-step explanation:
Since we have given that
Amount of budget = $18000
Expenses he spent to plant wheat = $8100
So, Total amount for acre is given by
[tex]\$18000-\$8100\\\\=\$9900[/tex]
Cost of each acre to plant = $47.00
So, the maximum number of acres of barley is given by
[tex]\dfrac{9900}{47}\\\\=210.63\\\\=211\ acres[/tex]
Hence, there is 211 number of acres of barley the farmer can plant and still be under budget.
