Answer:

The answer is 39.2

Step-by-step explanation:

The first thing you want to do is multiply both numbers by them selves like this: 9x8 and 4x8. Then after you do that, add the sum of those equations and you have your answer. Think about it like this, for 8x4, all it is is just 8+8+8+8. If solving it that way is easier for you, go for it! Hope I could help!

Question 9 Annabelle lives at Bermondsey in London. She has to speak at a conference in Birmingham at 10.30am. It will take her an hour from her home to get to Euston Rail Station, from where she will get a train to Birmingham. The train journey from Euston to Birmingham is an hour and 10 minutes. Trains to Birmingham run at the following times: 5 minutes past the hour, 25 minutes past the hour and 45 minutes past the hour. The meeting venue in Birmingham is a 5-minute walk from the station. What is the latest time that Annabelle can leave home, if she is to make it on time for the meeting in Birmingham? Show your working. (8 marks)​

Answers

Answer:

Step-by-step explanation:

working backwards

the five minute walk

10:30 - 0:05 = 10:25

train ride to Birmingham

10:25 - 1:10 = 9:15

Next earliest train departure time

9:05

Getting to Euston Station

9:05 - 1:00 = 8:05 am

Probably wise to leave a couple of minutes earlier to allow for minor emergencies on the way to Euston Station or to account for potential clock synchronization errors.

The train schedule already allows an additional 10 minutes of buffer time after boarding.

A home goods store sells 385 lamps in the month of July. If it sells 200 more
lamps in the next month, how many lamps does it sell in August?

Answers

Answer:

585

Step-by-step explanation:

We knew that the store sold 385 lamps in month of July. 200 more lamps were sold the next month which is August. Thus by addition, 585 lamps were sold in August.

What is addition?

Addition is one of the four basic operations of arithmetic, the other three being subtraction, multiplication and division. The addition of two whole numbers results in the total amount or sum of those values combined.

Lamps sold in July = 385

Given: 200 more lamps were sold in next month i.e., August.

Lamps sold in August = 385 + 200 = 585

2. What is the slope of the line through the points (-2, -1) and (4, 3)?
a) ⅖ b) 3/2 c) 5/2 d) ⅔

Answers

Answer:

1. (I need the picture for this one)

2. m=2/3 / Slope = 2/3

Step-by-step explanation:

I can’t help you with questions 1 because there is no picture. For question two, this is how you would find the slope given a line with 2 points:

Solving Steps: Reasoning:
1.) m=(y2-y1)/(x2-x1) [Slope Formula]
2.) m=(x1=-2, y1=-1) (x2=4, y2=3) [Assign Value to ordered pairs]
3.) m=(3-(-1))/(4-(-2)) [Substitution P.O.E.]
4.) m=(3+1)/(4+2) [Negative minus negative = positive]
5.) m=4/6 [Addition]
6.) m=2/3 [Simplification]

Therefore, the slope (m) = 2/3. To find the Domain, you will need to list all the X-coordinates from your ordered pairs. To find the range, you will need to list all the Y-coordinates from your ordered pairs.
You can use these formula:
Domain={x1, x2, x3, x4, x5…}
Range={y1, y2, y3, y4, y5…}
You just have to input your values into these formulas. An ordered pair looks like this: (5, 4). The left value is the x-coordinate (5), and the right value is the y-coordinate (4).

Divide 54 in to two parts so that four times the greater equals five times the less​

Answers

Answer:

Let the both the parts be 'x' and 'y'

x>y

We know that 4x = 5y

so x = 5y/4

x + y = 54

Replacing x we get

(5y/4) + y = 54

(5y +4y)/4 = 54

9y = 216

y = 24

Replacing y in ' x+y = 54'

we get x = 30

Step-by-step explanation:

Hence the larger part is 30 whereas the smaller part is 24

What is the equation of a line perpendicular to y= -3x+4 that passes through (-1, 6)

Answers

Have a good day sir!!!
Perpendicular lines have negative reciprocal slopes, in which the product of the slopes of both lines = -1.

Given the linear equation, y = -3x + 4 and the point, (-1, 6):

We can assume that the slope of the other line must be 1/3, because if you multiply 1/3 by -3, the product will be -1.

Substitute the values if the given point, (-1, 6) and the slope of the other line, m = 1/3 into the slope-intercept form to solve for the y-intercept (b) of the other line:

y = mx + b
6 = 1/3(-1) + b
6 = -1/3 + b

Add 1/3 to both sides
6 + 1/3 = -1/3 + 1/3 + b
19/3 = b

Therefore, given the slope of 1/3 and the y-intercept, b = 19/3, the equation of the other line is:

y = 1/3x + 19/3


Attached is a screenshot of the graph of both equations, proving that both lines are perpendicular from each other, and that y = 1/3x + 19/3 passes through point (-1, 6).

For the equation
y + 2 = 6(x - 5),
the line has a slope of 6 and contains what point?

Answers

Answer:

(5, -2)

Step-by-step explanation:

1. The equation "y + 2 = 6(x - 5)" is in the form of point-slope. Point slope form is [tex]y-y_1=m(x-x_1)[/tex] where y_1 = y-coordinate of point, m = slope, and x_1 = x-coordinate of point.

2. Given the information above, the point (5, -2) and slope of 6 makes the equation y + 2 = 6(x - 5) because:

[tex]y - y_1 = m(x-x_1)[/tex] [tex]y - (-2) = 6(x-5)[/tex] [tex]y + 2=6x-5[/tex]

Therefore, the point is (5,-2).
