If it takes you 40 seconds to travel from the first floor of a building to the third floor, how long will it take to travel from the first floor to the eighth floor (at the same pace, assuming all floors have equal height)? State your answer in seconds.
Answer: 104 seconds.
Step-by-step explanation: if it takes you 40 seconds to travel from the first to the third floor, then to pass one floor it will take 13 seconds. 40 divided by 3 which is 13. you then do 13x8 to figure out the time it would take you to travel through all the floors which is 104 seconds.
40/3 = 13
13 x 8 = 104
The answer is 104.
points A,B,and C are collinear. Point B is between A and C. AC= 3x+3, AB= -1+2x, and BC= 11. Find x
The value of x is -15 units when points A,B,and C are collinear. Point B is between A and C.
What is line segment?
It is a part of line having two ends points.
The simplest definition of a line is an arrangement of points that extends in opposite directions to infinity, while a ray is a section of a line that has one endpoint and extends continuously in one direction, while a segment of a line is a section of a line between two endpoints.
Here, it is given that points A,B and C are collinear that is all lies in the same plan and also :
Length of AC = 3x+3
Length of AB = -1+2x
and, BC = 11 units
Now, to calculate x we subtract length AB with AC and equate it to length of BC that is 11 units :
AB = AC + BC
-1+2x = 3x+3 + 11
3x-2x = -1 -3 - 11
x = -15 units
Therefore, the value of x is -15 units when AC= 3x+3, AB= -1+2x, and BC= 11.

Travis's income is $3400 a month, and he plans to budge 3/8 of his income of savings and 1/3 of his income for groceries.
Step 2: What amount of money does he intend to spend each month of these items together? Round your answer to the nearest dollar.
Travis's will spend each month is $2,408
How to calculate the amount Travis will spend each month ?Travis income is $3400
He plans to budge 3/8 of his income on savings
He also plans to give 1/3 of the income on groceries
The amount spent on savings is
= 3/8 × 3400
= 3 × 425
= 1,275
The amount spent on groceries is
1/3 × 3400
= 3400/3
= 1,133.33
The amount spent altogether is
1,133.33 + 1,275
= 2,408.3
Hence the amount Travis spent from his income each month is $2,408

Please help, and include an explanation as I would like to understand it!
The true statements about the numbers are:
The two numbers could be 180 and 36The two numbers could be 10 and 4The two numbers could be 8 and 5How to determine the two numbers each individual thinks?As a general rule, the product of any two numbers equals the product of the LCM and HCF of the numbers
Say, the two numbers are x and y;
Then, we have
x * y = LCM * HCF
Using the above as a guide, we have
Two numbers
x * y = 18 * 360
Express 360 as 10 * 36
x * y = 18 * 10 * 36
So, we have
x * y = 180 * 36
This means that
x = 180
y = 36
Hence, the two numbers could be 180 and 36
Emily's numbers
x * y = 1 * 40
Express 40 as 10 * 4
x * y = 1 * 10 * 4
So, we have
x * y = 10 * 4
This means that
x = 10
y = 4
Hence, the two numbers could be 10 and 4
Niamh's numbers
x * y = 8 * 5
Express 8 as 4 * 2
x * y = 4 * 2 * 5
So, we have
x * y = 8 * 5
This means that
x = 8
y = 5
Hence, the two numbers could be 8 and 5

When modeling hourly pay, which part of the equation is used to represent the
total pay?
A. X
B. y-intercept
C. y
D. None of the above
SUBMIT
When modeling hourly pay, the part of the equation used to represent the total pay is y ( Option C ).
The question asks when modeling hourly pay, which part of the equation is used to represent the total pay.
The given options are :
A. x
B. y-intercept
C. y
D. None of the above
This question can be easily solved using the slope intercept form of the line equation, that is, y = mx + c
where,
m is the slope of the line
and it represents the payment per hour
x is the independent variable
and it represents the number of hours
c is the intersection with the y axis
and it represents the signing bonus
y is the dependent variable
and it represents the total pay
From the above information, it can be inferred that when modeling hourly pay, the part of the equation used to represent the total pay is represented with y in the slope intercept form y = mx + c
Therefore, using the slope intercept form, we get the part of the equation used to represent the total pay as y ( Option C ), when modeling hourly pay.

A. 20.63° B. 69.37° C. 19.41° D. 9.83°E. 46.90°
The measure of the angle is 20.63 degrees if the lengths of the hypotenuse and one leg of a right triangle are 10.5 and 3.7, respectively option (A) is correct.
What is a right-angle triangle?It is a triangle in which one of the angles is 90 degrees and the other two are sharp angles. The sides of a right-angled triangle are known as the hypotenuse, perpendicular, and base.
It is given that:
The lengths of the hypotenuse and one leg of a right triangle are 10.5 and 3.7, respectively.
As we know,
Applying sin ratio
sinA = perpendicular/hypotenuse
sinA = 3.7/10.5
sinA = 0.35
sinA = 20.63 degrees
Thus, the measure of the angle is 20.63 degrees if the lengths of the hypotenuse and one leg of a right triangle are 10.5 and 3.7, respectively option (A) is correct.
