Emily spent £2400 on holiday in 2017.
This was 20% more than she spent on holiday in 2016.
Calculate the amount she spent on holiday in 2016.
Answers
Answer:
£1920
Step-by-step explanation:
The amount she spent in 2016 is 20% less than 2017. 20% less than is the same as 80% of the amount she spent in 2017. So, to find how much she spent in 2016, multiply 2400 by 0.80 (the decimal form of 80%):
2400 * 0.8 = 1920

ra\\For spirit week at a local high school, students were encouraged to wear their school colors of green and white. 1,200 students wore their school colors while 300 students did not wear green and white. What percent of the school population did NOT wear their school colors?
Answers
Answer:
20%
Step-by-step explanation:
First, add 1,200, and 300. That gives you 1,500. You want to find how much percent of 1,500 equals 300, and that is 20%.
Answer:
25%
Step-by-step explanation:
1. You have a total of 1,200 students and a fraction of them did not wear their school colors, 300 students.
2. You would write the fraction [tex]\frac{300}{1200}[/tex].
3. After you divide or simpify [tex]\frac{300}{1200}[/tex] you get [tex]\frac{1}{4}[/tex].
4. To get a percent you multiply by 100, so [tex]\frac{1}{4}[/tex] times 100 is equal to 25.

Step 1: Define
f(x) = x² + 2x - 6
g(x) = x + 5
(f - g)(x) is f(x) - g(x)
Step 2: Find
Substitute: (f - g)(x) = x² + 2x - 6 - (x + 5)Distribute -1: (f - g)(x) = x² + 2x - 6 - x - 5Combine like terms: (f - g)(x) = x² + x - 11Find the equation for a polynomial f(x) that satisfies the following:

Answer:
f(x) = 1/2(4 - x)(x - 1)(x - 2)Step-by-step explanation:
Considering zero's and a coefficient, the function is:
f(x) = a(x - 4)(x - 1)(x - 2)Considering y-intercept:
f(0) = a(0 - 4)(0 - 1)(0 - 2)4 = a(-4)(-1)(-2)4 = -8aa = -1/2So the function is:
f(x) = -1/2(x - 4)(x - 1)(x - 2) = 1/2(4 - x)(x - 1)(x - 2)

 Write an equation in slope intercept form of the line shown. (4,1) (8,4)
Answers
Answer:
Y = 3/4x - 2
Step-by-step explanation:
Slope (rise/run) is 3/4 and the y-intercept is -2.
Hope this helps. Pls give brainliest.
An equation in slope intercept form of the line shown (4,1) and (8,4) is y=3/4 x-2.
The given coordinate points are (4, 1) and (8, 4).
What is the slope intercept form?The slope intercept form of a straight line is one of the most common forms used to represent the equation of a line. The slope intercept formula can be used to find the equation of a line when given the slope of the straight line and the y-intercept.
The standard form of the slope intercept form is y=mx+c.
Here, slope = (y2-y1)/(x2-x1)
= (4-1)/(8-4)
= 3/4
Put m=3/4 and (x,y)=(4,1) in y=mx+c
1=3/4 (4)+c
⇒c=-2
Now, substitute m=3/4 and c=-2 in y=mx+c and simplify
That is y=3/4 x-2
Therefore, an equation in slope intercept form of the line shown (4,1) and (8,4) is y=3/4 x-2.

8 1/4 pounds of flour are used to make 4 1/8 papier-mâché pasta recipe how much flour is used in one recipe
Answers
Answer:
1/6
Step-by-step explanation:
ive seen that question b4
2 pounds of flour are required to make 1 recipe, as of the given condition.
Given that
8 1/4 pounds of flour are used to make 4 1/8 paper-mâché pasta recipe how much flour is used in one recipe is to be determined.
The process in mathematics to operate and interpret the function to make the function or expression simple or more understandable is called simplifying and the process is called simplification.
Here,
Flour = 8 1/4
Flour = 8.25 pounds
The proportion of the recipe made corresponding to 8.25 pounds of flour = 4.125
Now,
For 1 recipe = 8.25 / 4.125 = 2 pounds of flour are needed.
Thus, 2 pounds of flour are required to make 1 recipe, as of the given condition.

Rod is paid $85 to install a screen door and $115 to install a wooden door. In one week he installed 18 doors and was paid a total of $1860. How many screen doors did Rod install?
Answers
Answer:Rod installed 7 screen doors
Step-by-step explanation:
Step 1
Let the number of screen door = x
And the number of wooden doors = y
since he installed 18 doors , we have that
screen door + wooden doors = 18
x + y = 18------ equation 1
Also the cost to install a screen door -= $85
and to install a wooden door = $115
And he was therefore paid a total of $1850
Therefore
85x + 115 y = $1860------- equation 2
Step 2----- Solving
x + y = 18------ equation 1
85x + 115 y = $1860------- equation 2
Multiplying equation 1 BY 85
85x + 85y= 1530------- equation 3
85x + 115 y = $1860------- equation 4
subtracting from equation 1 from (2)
115y- 85y= 1860-1530
30y=330
y = 330/30 = 11
To find x
x+ y=18
x= 18-y
x= 18-11= 7

Explanation:To find the x substitute 0 in for y,7x+3*0=21.Next,multiply 3 and 0,and that gives you 0,7x+0=21 .After you do that you need remove 0 because when you add and subtract zero the quantity doesn’t change,7x=21.Lastly,divid both sides of the equation by 7,and that gives you x=3.
