Answer:
d = 36 km
Step-by-step explanation:
Speed of Jim, v = 18 km/h
Time, t = 2 hours
We need to find the distance covered. We know that the speed of an object is equal to the distance covered by it divided by total time taken.
[tex]v=\dfrac{d}{t}\\\\d=v\times t\\\\d=18\ km/h\times 2\ h\\\\=36\ km[/tex]
So, he will cover 36 km.

Find the slope of line then put the answer as a integer or as a reduced fraction in the form A/B
Answer:
-1/12
Step-by-step explanation:
The line passes through (0,10) and (-600,60)
So m = (60 - 10)/(-600 - 0) = 50/(-600) = -1/12

y = x

Answer:
C. x - y = 0
Step-by-step explanation:
First find write the equation in slope-intercept form, then rewrite to convert to standard form as Ax + By = C.
Equation in Slope-intercept form:
Find m and b
m = rise/run = 1/1 = 1
b = y-intercept = 0 (where the line intercepts the y-axis)
Substitute m = 1, and b = 0 into y = mx + b
Thus:
y = (1)(x) + 0
y = x
Rewrite to convert to standard form.
Thus, the equation in standard form would be:
x - y = 0
5/8 and 3/4 I need an answer pleaseee
I'm not sure what you mean but I'll provide both.
5/8 + 3/4
11/8 or 1 3/8.
The common denominator of 5/8 and 3/4 is 8. 3/4 with a denominator of 8 would be 6/8.
5/8 + 6/8 = 11/8 or 1 3/8.
5/8 × 3/4
15/32.
Multiply the numerator by the numerator and the denominator by the denominator.
5 times 3 is 15 and 8 times 4 is 32.
So you get 15/32. This cannot be simplified.

The equation y=6.88x-199 models the number of visitors at a pool,y, and the air temperature in degrees there are 426 visitors at the pool one hot day what is the expected air temperature on that da round your answer to the nearest degree
Answer:
[tex]\approx 91^\circ[/tex]
Step-by-step explanation:
The given equation to represent the model for the relationship between [tex]x[/tex] and [tex]y[/tex].
[tex]y=6.88x-199[/tex]
[tex]x[/tex] represents the air temperature in degrees and
[tex]y[/tex] represents the number of visitors at a pool.
Also given that number of visitors at the pool on a particular day is 426.
To find:
The expected air temperature as per the number of visitors.
Solution:
Here, we are given a linear equation to represent the relation between two variables.
Value of one variable is given and we have to find the value of other variable.
i.e. we are given that:
[tex]y=426[/tex] and we have to find the value of [tex]x[/tex].
Let us put the value in the equation:
[tex]426=6.88x-199\\\Rightarrow 6.88x = 426 + 199\\\Rightarrow x = \dfrac{625}{6.88}\\\Rightarrow \bold{x \approx 91^\circ}[/tex]

Which of the following expressions represents 3 less than 5 times a number
A) 5n - 3
B) 5 - 35
C) 3n - 5
D) 3 - 5
Answer:
A)
Step-by-step explanation:
The correct expression which represents ''3 less than 5 times a number'' would be,
A) 5n - 3
Mathematical expression is defined as the collection of numbers variables and functions by using operations like addition, subtraction, multiplication, and division.
Given that,
A mathematical expression is,
''3 less than 5 times a number''
Let us assume that,
A number = x
Hence, the expression to represent ''3 less than 5 times a number'' is,
⇒ (5 × n) - 3
⇒ 5n - 3
So, the correct option is,
A) 5n - 3

Find the sample variance and standard deviation
19,12,6,7,11
Thank you
Answer:
Variance: 26.5
Standard Deviation: 5.1478150704935
Step-by-step explanation:
First, Add up all of the numbers: 6 + 7 + 11 + 12 + 19 = 55
Square the total, and then divided the number of items in the data set55 x 55 = 3025
3025 / 5 = 605
Take your set of original numbers from step 1, squared them individually this time, and added them all up:(6 x 6) + (7 x 7) + (11 x 11) + (12 x 12) + (19 x 19) = 711
Subtract the amount in step 2 from the amount in step 3:711 - 605 = 106
Subtract 1 from the number of items in my data set:5 - 1 = 4
Divide the number in step 4 by the number in step 5:106 / 4 = 26.5
Finally, take the square root of the number from step 6 (the variance),
√(26.5) = 5.1478150704935

What is the result of isolating x² in the equation below?
(x+1)² + (y-8)² = 9
OA. x²=-y²-2x+16y-56
OB. x² = y² +2x+16y+56
C. x = -² -56
D. * = y² +56
The required result of the identity is [tex]x^{2} =-y^{2}-2x+16y-56[/tex].
To isolate the algebraic expression given below we need to simplify it and then make [tex]x^{2}[/tex] the subject of the equation,
For that we must know the identity [tex](a+b)^{2}=a^{2}+2ab+b^{2}[/tex].
We will break the given equation on the basis of the given identity.
Now, [tex](x+1)^{2} +(y-8)^{2}=9\\[/tex]
⇒[tex]x^{2} +2x+1+y^{2}-16y+64=9\\[/tex]
⇒ [tex]x^{2} =-y^{2}-2x+16y-56[/tex]
So, the required result of isolating the above given equation is as above.
The correct answer is option B.

Remember, plug into point-slope, y - y, = m(x - x,), then solve down I
Passes through (7, 4) with a slope of -3
The slope-intercept equation of the given line is 3x + y = 25
Slope-intercept is one of the special forms of linear equations where we can find the slope-intercept of any point with its coordinates and its slope.
The line is passing through the point(x₁,y₁) = (7,4)
The slope of the line line(m) = -3
Slope-intercept equation
y-y₁ = m( x- x₁)
Where (x₁,y₁) is (7,4) and Slope,m is -3
Let us substitute these values in the slope-intercept equation, It becomes
y - 4 = -3(x - 7)
y - 4 = -3x + 21
3x + y = 21 + 4

Every month, Veronica deposits $230 in an account with an interest rate of 6% compounded monthly. How much money will she have in the account at the end of the first 5 years? (Round to the nearest cent. Do not enter the $ sign.)
Answer:
Veronica will have $310.04 at the end of first five years.
Step-by-step explanation:
Principal Amount P = $230
Interest Rate r = 6%
Time t = 5 years
Compounded monthly n = 12
We need to find the future amount (A)
The formula used is: [tex]A=P(1+\frac{r}{n})^{nt}[/tex]
Putting values and finding A
[tex]A=P(1+\frac{r}{n})^{nt}\\A=230(1+\frac{0.06}{12})^{5*12}\\A=230(1+0.005)^{60}\\A=230(1.005)^{60}\\A=230(1.348)\\A=310.04[/tex]
