Round 1.5 to one decimal place
Answer:
2
Step-by-step explanation:
Since rounding to the one place relies on the decimal part, the part to focus on is the .5
becuase anything greater or equal to 5 is rounded up, the answer is 2
1.5 rounded to one decimal place will be 2.
What are Places' values?Place value can be defined as the value represented by a digit in a number on the basis of its position in the number.
Given a fraction number 1.5 that needed to be rounded to one decimal place. Since it's at the equidistance from the nearest whole number then we will follow the even number rule.
Rounds towards the nearest neighbor, but if equidistant, it rounds towards the even number. Both 1.5 and 2.5 are rounded to 2
therefore, 1.5 will be 2, when rounded to the nearest tenth.

The San Francisco half-marathon is a 13.6-mile race that travels up and down the hills of San Francisco. One street, Folsom Street, has a slope that can be represented by the function 2y=4x+7. Another street, Divisadero Street, has a slope that can be represented by the function 5y = 2x +9.
Which of these hills would you rather run-up? Why? Use evidence to support your answer.
Answer:
Step-by-step explanation:
Ok, from what I just reviewed, once you get the equation into the form of y = mx + b, the m is the slope of a line.
So take the first street, Folsom
2y = 4x + 7
y = 2x + 7/2
the slope is 2.
The second street, Divisadero
5y = 2x + 9
y = 2/5x + 9/5
the slope is 2/5.
So whether we're talking about 2/5 of an inch, 2/5 of a foot, or 2/5 of a mile, 2/5 is less than 2, so I would rather go up the less steep road...Divisadero.

The measure of L in triangle LMN is 32°. The measure of M is 69°. What is the measure of N?
A.
79°
B.
259°
C.
101°
D.
37°
Answer:
A) 79
Step-by-step explanation:
m<N = x
All angles in a triangle add up to 180 so:
x + m<L + m<M = 180
x + 32 + 69 = 180
x + 101 = 180
x = 180 - 101
x = 79
Answer:
It is (A) 79°
The summation of the triangle's angles are 180°
Step-by-step explanation:
[tex]m + l + n = 180 \\ 69 + 32 + n = 180 \\ n = 180 - 101 \\ n = 79 ^{ {} ^{.} } [/tex]

This is a scale drawing of a flag. The scale factor of a drawing to the actual flag is represented by the ratio 1:18. What is the area, in
square inches, of the actual flag?
Answer:
648 sq. in.
Step-by-step explanation:
The ratio of the flag is 1:18 and the question asks for the area of the flag.
To find the actual flag size, you got to multiply the width by 18.
Then you must multiply the length by 18.
A= LxW
A=36 x 18
A= 648 sq. in.
Therefore, the area of the actual flag is 648 sq. in.
Lin's job pays $8.25 an hour plus $10 of transportation allowance each week. She has to work at least 5 hours a week to keep the job, and can earn up to $175 per week (including the allowance). Represent this situation mathematically in two inequalities. Let `x` represent the number of hours Lin works in a week. Inequality 1:
Answer:
Kindly check explanation
Step-by-step explanation:
x = number of hours Lin works in a week
Inequality (1) : Least Numbe rod hours worked
x ≥ 5 - - - (1)
Possible earning including transportation allowance :
8.25x + 10 ≥ 175 - - - (2)
Solving for X from (2)
8.25x ≥ 175 - 10
8.25x ≥ 165
x ≥ 20 hours
To earn upto 175 per week, then he has to work for 20 hours
How many 2-liter bottles of soda will you need to fill ten 500 milliliter containers?
Answer:
2.5 bottles
Step-by-step explanation:
10 * 500 ml = 5000 ml
5000 ml = 5 l
5/2 = 2.5
2-liter bottles of soda will need 2.5 bottles to fill ten 500 milliliter containers.
How many milliliters in 1 liter?A liter is a cubic meter unit of volume which is equal to 1000 cubic centimeters.
1 liter = 1000 milliliters
Ten 500 milliliter containers
10 × 500 ml = 5000 ml
5000 ml = 5 l
2-liter bottles of soda will you need
5/2 = 2.5bottles
Therefore, 2-liter bottles of soda will need 2.5 bottles to fill ten 500 milliliter containers.

A line passes through the point (3,3) and is parallel to the line given by the equation Y=-2/3x - 2
What is the equation of the line?
A. Y=3/2x
B. Y=-2/3x+5
C. Y=2/3x-5
D. Y=-3/2x+1
Answer:
B. [tex]y=-\frac{2}{3}x+5[/tex]
Step-by-step explanation:
Equation of a line: y=mx+b (Where m is the slope and b is the y- intercept)
Parallel lines have the same slope.
So that means that the line will have the slope [tex]-\frac{2}{3}[/tex].
So we can write the equation of the line as y= -2/3x+b
Since it goes through the point (3,3) we can plug in 3 for x and y by doing:
[tex]y=-\frac{2}{3} x+b\\3=-\frac{2}{3} (3)+b\\3=-2+b\\b=5[/tex]
Now we know the y intercept (b) we can write the equation of the line.
[tex]y=-\frac{2}{3}x+5[/tex]
The equation of the line would be equal to y= -2/3x + 5
What is the Point-slope form?The equation of the straight line has its slope and given point.
If we have a non-vertical line that passes through any point(x1, y1) and has a gradient m. then general point (x, y) must satisfy the equation
y-y₁ = m(x-x₁)
The Equation of a line: y=mx+b
Where m is the slope and b is the y- intercept
Since Parallel lines have the same slope.
So we can write the equation of the line as;
y= -2/3x+b
Since it goes through the point (3,3) we can plug in 3 for x and y
y= -2/3x+b
3 = -2 + b
b = 5
Now we know the y intercept (b) we can write the equation of the line.
y= -2/3x + 5

Step-by-step explanation:
Let's start with the easy parts of the perimeter...the flat parts...7 + 7 = 14. We'll add that to the arch shortly.
We need to find the circumference of the whole circle, then divide by 4 to get 1/4 of a circle. (There might be a faster way, but this gets the job done.)
circumference = (2)(pi)(r)
= 2(3.142)(7) = 43.988
Now divide that by 4 for the distance of the arch.
43.988/4 = 10.997
Add that to the flat parts
10.997 + 14 = 24.997

How to form two-way table?Suppose two dimensions are there, viz X and Y. Some values of X are there as X_1, X_2, ... , X_n and some values of Y are there as Y_1, Y_2, ... , Y_n
List them in title of the rows and left to the columns. There will be n \times k table of values will be formed(excluding titles and totals), such that:
Value(ith row, jth column) = Frequency for intersection of X_i and Y_j (assuming X values are going in rows, and Y values are listed in columns).
Then totals for rows, columns, and whole table are written on bottom and right margin of the final table.
For n = 2, and k = 2, the table would look like:
[tex]\begin{array}{cccc}&Y_1&Y_2&\rm Total\\X_1&n(X_1 \cap Y_1)&n(X_1\cap Y_2)&n(X_1)\\X_2&n(X_2 \cap Y_1)&n(X_2 \cap Y_2)&n(X_2)\\\rm Total & n(Y_1) & n(Y_2) & S \end{array}[/tex]
where S denotes total of totals, also called total frequency.
n is showing the frequency of the bracketed quantity, and intersection sign in between is showing occurrence of both the categories together.
We are given that;
The table
Now,
the number of subscribers to the magazine is decreasing exponentially because it is decreasing by a fixed percentage each year. The base of the exponential function is less than 1, which means that the function is decreasing. The inverse of an exponential function is a logarithmic function, which has the form f(x) = log_a(x), where a is the base of the exponential function. To find the inverse of an exponential function, you need to swap the x and y variables and solve for y using logarithms. For example, if f(x) = 2^x, then f^-1(x) = log_2(x).
Therefore, by the table the answer will be exponentially
