The number rounded to the nearest ten will be 1640. The number is grater than the 5 on the scale.
What are rule for finding a number rounded to the nearest ten?If the digit in the units place is between 0 and 10 i.e., 5, then the unit digit is substituted by 0.
If the digit in the units place is between 5 and 9, that is, > or 5 but less than 10, the units place is replaced by '0,' and the tens place is incremented by 1.
The given number is;
x=1637.984
The number is 7.9 grater than 5. So that the number is rounded to the nearest whole number,i.e.1640
Hence,the number rounded to the nearest ten will be 1640.

Find the slope of a line that passes through the points (2, 3) and (0, 2).
(slope, 50 points.)
Answer:
1/2
Step-by-step explanation:
To find the slope, we can use the slope formula
m = ( y2-y1)/(x2-x1)
= ( 2-3)/(0-2)
= -1/-2
= 1/2
Answer:
Slope = 0.5
Step-by-step explanation:
Given: Line passes through (2, 3) and (0, 2)
[tex]\text{Slope formula} = \dfrac{\text{Rise}}{\text{Run}} = \dfrac{y_2 - y_1}{x_2 - x_1}[/tex]
Substitute the coordinates in the formula and solve for the slope;
[tex]\implies \text{Slope formula} = \dfrac{y_2 - y_1}{x_2 - x_1}[/tex]
[tex]\implies\text{Slope formula} = \dfrac{2 - 3}{0 - 2}[/tex]
[tex]\implies\text{Slope formula} = \dfrac{-1}{-2}[/tex]
[tex]\implies\text{Slope formula} = \dfrac{1}{2} = 0.5[/tex]
Therefore, the slope of the line is 0.5.
Dividing a decimal number that is ________ than 1 gives a quotient that is larger than the dividend.
Answer:
Suppose we want to divide 3 by 2.
By Long Division we first write 1 as the first digit as the quotient, then we subtract 2 from 3, then we add a zero to the remainder 1, and then add a decimal point after the quotient 1, then write 5 after the decimal point, getting the quotient as 1.5
I know it is indeed right as we can verify. But why do we add a zero and the decimal point in the quotient?
Thank you.
Answer:
less
Step-by-step explanation:
Dividing a decimal number that is less than 1 gives a quotient that is larger than the dividend.
For example :
Take 3/0.3 :
⇒ 3 / 0.3
⇒ 10
10 is greater than the dividend 3.
A ladder is leaning against a house at an angle of 35° at the roof line. The base of the ladder is 8 feet from the house. How long is the ladder to the nearest whole foot? Use a calculator if needed.
A. 27 feet
B.43 feet
C. 8 feet
D. 14 feet
E. 35 feet
Answer:
D
Step-by-step explanation:
Remark
What you are trying to solve for is the hypotenuse of a right triangle. You will use the sine to do it.
Givens
Base = 8 feet
angle = 35 degrees
hypotenuse = ?
Formula
Sin(35) = base / hypotenuse
Solution
Sin (35) = 8 / hypotenuse Multiply both sides by the hypotenuse
hypotenuse * sin(35) = hypotenuse * 8/hypotenuse
hypotenuse * sin(35) = 8 Divide by sin(35)
hypotenuse = 8/sin(35) Substitute value of sin(35)
hypotenuse = 8 / 0.5736
hypotenuse = 13.94
Answer
The ladder is about 14 feet long or D
Provide the reflected ordered pair for each of the given ordered pairs.
Answer:
so i have a little trick for you. Reflecting across the x axis is just turning (x,y) to (x, -y)
Reflecting across the y axis is just turning (x, y) to (-x, y)
If we substitute that in we can figure it out
so
(0, 3) we have to turn it to (x, -y), so it would end up being (0, -3). That is the reflection axross the x axis.
(-4,5) we have to turn it to (-x,y) which will be (4,5) because a negative and a negative is positive. so (4,5) is the ordered pair reflected across the y axis! Hope it helps :D

1.Does the relationship between number of people and the bill appear to be weak, moderate or strong?
2.Does the relationship between number of people and the bill appear to be linear?
3.The equation of the line of best fit is Bill = 5.80 + 11.15 · People. (y=5.80+11.15x) Sketch this line on the scatterplot.
4.Interpret the slope of the line of best fit in the context of this problem.
5.Note that the points in the scatterplot do not all lie on the line. What could explain this variability?
6.Use the equation of the line of best fit to estimate how much would you predict the bill to be for a party of 8?
7.There was one party of 8 whose bill was $82.50. Did they pay more than or less than the predicted amount? How much more or how much less did they pay?
The relationship depicts to be fairly strong and also linear as the points on the graph doesn't move far from a line.
What is the relationship about?The interpretation of the slope of the line of best fit in the context of this problem is that the additional person added to the party will bring or add about $11.15 to the bill above.
The variability can be shown or explained by the differences that are seen in what the parties in the graph has ordered to eat or drink.
Since the party of 8 paid were said to have paid (95 - 82.50 =12.50) therefore, 12.50 is known to be less than the predicted amount.

Explanation:
[tex]f(x)= -13x^2+15\\\\f(x)= -13x^2+15*1\\\\f(x)= -13x^2+15x^0\\\\[/tex]
Each term of the polynomial function has an exponent which is an even number, therefore the function is even.

Another approach:
[tex]f(x)= -13x^2+15\\\\f(-x)= -13(-x)^2+15\\\\f(-x)= -13x^2+15\\\\[/tex]
Since f(x) = f(-x) for all x, this proves the function is even.

an angle is 10 degrees more than 3 times the measure of its compliment. find the measure of both angles
Answer:
20° and 70°
Step-by-step explanation:
complimentary angle sum to 90°
let x be the compliment then the angle is 3x + 10 , so
x + 3x + 10 = 90 , that is
4x + 10 = 90 ( subtract 10 from both sides )
4x = 80 ( divide both sides by 4 )
x = 20
3x + 10 = 3(20) + 10 = 60 + 10 = 70
the 2 angle measures are 20° and 70°
