Answer:
200
Step-by-step explanation:
Jack share = 2/5 x 1/5 = 2/25
amount left over = 1 - (2/25 + 2/5) = 13/25
13/25 x t = 260
t = total amount of chocolate
t = (260 x 25) / 13 = 500
Davids share = 2/5 x 500 = 200
A shop keeper buys a pair of shoes for birr 180 and sells it for birr 225 what is the percentage profit
Answer:
Percentage profit = 20%
Step-by-step explanation:
Given the following data;
Cost price = birr 180
Selling price = birr 225
To find the percentage profit;
First of all, we would determine the profit;
Profit = selling price - cost price
Profit = 225 - 180
Profit = birr 45
Next, we would determine the percentage profit;
[tex] Percentage \; profit = \frac{profit}{selling \; price} * 100[/tex]
[tex] Percentage \; profit = \frac{45}{225} * 100[/tex]
[tex] Percentage \; profit = 0.2 * 100[/tex]
Percentage profit = 20%

PLEASE HELP Which composition of similarity transformations
maps ALMN to A L'M'N'?
a dilation with a scale factor less than 1 and then a
reflection
a dilation with a scale factor less than 1 and then a
translation
a dilation with a scale factor greater than 1 and then
a reflection
a dilation with a scale factor greater than 1 and then
a translation
Answer:
a dilation with a scale factor greater than 1 and then a translation (the last option)
The composition of transformation is a dilation with a scale factor greater than 1 and then a translation.
What is Translation?A translation only moves a shape up, down, or from side to side; it has no effect on how it appears.
We have a transformations maps LMN to L'M'N'.
As the size of Triangle L'M'N' is larger as compared to LMN.
The compression is represented by a scale factor with an absolute value between 0 and 1, while the enlargement is represented by a scale factor with an absolute value greater than 1.
Thus, dilation with a scale factor greater than 1 and then a translation.

A line is parallel to 5x+2y-8-0 and has the same y-intercept as x+4y-12-0.
Find the equation for the line in slope y-intercept form
Answer:
y=(-5/2)x+3
Step-by-step explanation:
5x+2y-8=0
2y=-5x+8 Divide with 2
y=(-5/2)x+4
Slope is dy/dx
dy/dx=-5/2
x+4y-12=0 for x=0
4y-12=0
4y=12 Divide with 4
y=3 y-intercept
Line equation:
y = mx + b
This is called the slope-intercept form because "m" is the slope and "b" gives the y-intercept.
m-5/2 b=3
Euation for the your line:
y=(-5/2)x+3

find the equation of the line passing through (-5, -4) and (13, 5)
Answer:
y = 1/2x - 3/2
Step-by-step explanation:
y2 - y1 / x2 - x1
5 - (-4) / 13 - (-5)
9 / 18
1/2
y = 1/2x + b
-4 = 1/2(-5) + b
-4 = -5/2 + b
-3/2 = b

A mathematics teacher wanted to see the correlation between test scores and homework. The homework grade (x) and test grade (y) are given in the accompanying table. Write the linear regression equation that represents this set of data, rounding all coefficients to the nearest tenth. Using this equation, find the projected test grade, to the nearest integer, for a student with a homework grade of 34.
SOMEONE HELP ME WITH THIS RIGHT NOW. please
Answer:
23
Step-by-step explanation:
Using an online calculator and plugging the values in, we get our equation of y=mx + b to become y = 1.2x - 17.8 .
Plugging 34 in for x, we get 1.2(34) - 17.8 = 23 for their projected test grade

Which of the following expressions represents the distance between-1/4 and 3/4
Answer:
|-1/4 - 3/4|
Step-by-step explanation:
To get the distance, take the absolute value of the second point minus the first point
| 3/4 - - 1/4|
|3/4 + 1/4|
We can also take the absolute value of the first point minus the second point
|-1/4 - 3/4|

Liam spent $4.76 on a salad bowl, and $3.81 on a cup of coffee. He paid using TWO ten dollar bills. What was Liam's change?
Answer:
11.43
Step-by-step explanation:
You can start this by adding the total cost of the salad and the coffee.
4.76 + 3.81 = 8.57
Then you have the paid amount of 20 bucks because there was two tens.
20 - 8.57 = 11.43.

The number of pages in an Algebra book is 99 less than the number of pages in a geometry book.
Write and solve an equation to find the number n of pages in the geometry book.
Answer: An equation is *629 = n - 99. The geometry book has 728 pages*
Step-by-step explanation: The Algebra book has 99 pages LESS than the geometry book, in other words, the geometry book has 99 pages MORE than the Algebra book. This equation can be used to find the answer. I’m afraid 530 is not the answer.
