Answers
Answer:
it says LESS THAN not less tha n or equal to so it cant be a or b or d, so it is c!
Step-by-step explanation:
Catherine bought apples and pears for the school picnic. If the total fruit is less than 100, then the correct equation for this will be y<100-x and y<x. Hence, option C is correct.
What is an equation?Equations are mathematical expressions that have two algebra on either side of an equal (=) sign. The expressions on the left and right are shown to be equal to one another, demonstrating this relationship. L.H.S. = R.H.S. (left-hand side = right side) is a fundamental simple equation.
As per the given data in the equation,
Catherine bought apple and pears.
The overall quantity is less than 100
Let the number of apples is x and,
The number of pears is y.
She bought more apples than pears,
y<x.
And y < 100-x.

The trend line passes through (10,9) and (35,0). Write an equation for the trend line.
Answers
Answer: Solution :
Step 1 :
Make a scatter plot of Lily’s running data.
Step 2 :
To draw a trend line, use a straight edge to draw a line that has about the same number of points above and below it. Ignore any outliers.
Step 3 :
Find the slope of the trend line.
The line passes through points (2, 20) and (4.5, 45).
Use the slope formula.
m = (y2 - y1) / (x2 - x1)
Substitute x1, = 2, y1 = 20, x2 = 4, and y2 = 45.
m = (45 - 20) / (4.5 - 2)
m = 25 / 2.5
m = 10
Step 4 :
Find the y-intercept of the trend line.
Slope-intercept form equation of a line :
y = mx + b
Plug y = 20, m = 10 and x = 2.
20 = 10 · 2 + b
20 = 20 + b
Subtract 20 from both sides.
0 = b
Step 5 :
Use your slope and y-intercept values to write the equation.
Slope-intercept form equation of a line :
y = 10x + 0
So, the equation for the trend line is
y = 10x

Answers
Answer:
30.4%
1000 at £1.10
1000 x 1.10 = £1100
35% of 1000 is given away
1000 - 35% = 1000 - 350 = 650 left
35% of £1100 = £385, subtract to get £715 pounds worth of pins left
650 are left, with 385 pounds lost
60% of 650 = 390 pins sold at £3 each
40% of 650 = 260 sold at £5 for 2
3 x 390 = £1170 made from the first lot
260/2 = 130 x 5 = £650 made from the second lot
£1170 + £650 = £1820 from sales
Sales - cost to make - losses (giveaways) = profit value
1820 - 1100 - 385 = 335 pounds of profit
To find the gross profit margin, we take the profit, and find what percentage of the production cost it is.
335 is about 30.45% of 1100
30.45%, which is 30.4% to 1 decimal place.

2. Same thing except 25 goes into 100 four times so I multiple the 3 and 25 by four and get 12/100 so it’s 12%.
3. Do 3 divided by 16, and you get .1875. So that’s 18.75% or you can do 100 divided by 16 and get 6.25. Then you multiply the 6.25 times the 3 and get 18.75%
