A furniture store owner buys a sofa for $400 and marks it up %90 to sell it. During the stores anniversary sale she sells the sofa for %25 off. How much profit will the store owner make on the sofa during the anniversary sale?
Answer:
Anniversary sale price= $570
Step-by-step explanation:
Giving the following information:
Purchase cost= $400
Mar-up percentage= 90%
First, we need to calculate the "normal" selling price:
Selling price= 400*1.9= $760
Now, we can determine the anniversary sale price:
Anniversary sale price= 760 - (760*0.25)= $570

a tree of 14 m height is broken so that its top touches ground and makes an a 60 degeree.find the length of broken part of tree
Answer:
98 - 24√3 is your answer dear.
Step-by-step explanation:
Let the length of broken part of the tree = 14 - x
For finding x
sin60° = √3/2 = x /14-x
14√3 - √3x = 2x
14√3 = 2x + √3x
14√3 = (2 + √3)x
x = 14√3/(2 + √3)x
after rationalisation
x = 24√3 - 84
substract it 14 - (24√3 - 84)
YOU'LL GET 98 - 24√3 WHICH IS YOUR ANSWER.

Ann and Ruth bowled together and had a combined score of 410 points. Ann's score was 44 points less than Ruth's score. Write a system of equations that can be used to determine x, Ann's score and y, Ruth's score.
Answer:
x=y-44 and x+y=410
Step-by-step explanation:
So, you want to use the equations x=y-44 and x+y=410 when x is Ann's score and y is Ruth's score. This is because x (Ann's score) is Ruth's score (y) but 44 less, so you subtract y-44 to get x. Then x+y would also have to equal 410 so that's the other equation. Graphing the 2 equations gets you to the point (183,227) in which Ann's score is 183 points and Ruth's score is 227 points.

i need help finding the value of x and the measure of each angle
Answer:
x=7, angle a= 45 degrees, angle b= 65 degrees
Step-by-step explanation:
All the angles in a triangle must add up to 180. Subtract 70 from 180, add both angle a and angle b to get 16x-2=110, solve for x, x=7. Substitute x out for 7 in the equations then simplify to get angle a=45 and angle b=65
Answer:
x = 7
m∠B = 65
m∠A = 45
Step-by-step explanation:
So we know that the inside of a triangle equals 180º. So we have one angle already, 70º, so what we can do is subtract 70 from 180.
180 - 70 = 110
Now we can set both equations equal to 110.
2 + 9x + 7x - 4 = 110
Now simplify.
2 + 9x + 7x - 4 = 110
2 + 16x - 4 = 110
16x - 2 = 110
+2 +2
------------------
16x = 112
÷16 ÷16
-----------------
x = 7
So now you can just plug 7 in for x to check your answers
2 + 9(7) = 65
7(7) - 4 = 45
65 + 45 + 70 = 180
Can someone help me out with this inequality problem?? Will give brainliest to best answer!!
Answer:
250x + 525y ≤ 7800
no, 15 refrigerators and 8 pianos will not fit on the truck
Step-by-step explanation:
we know that x is the refrigerators and each one is 250 lbs
this can be written as 250x
we know that y is the pianos and each one is 525 lbs
this can be written as 525y
we also know that "no more than" is the same that as less than equal to
so this can be written as ≤
we can also say that the refrigerators and pianos has to be ≤ 7800
so now we have: 250x + 525y ≤ 7800
plug in 15 to x and 8 to y
250(15) + 525(8) ≤ 7800
3750 + 4200 ≤ 7800
7950 ≤ 7800
this statement is not true so no, 15 refrigerators and 8 pianos will not fit on the truck

The required simplified value of the given expression at x = -4 and y = 4 is 16, 385/4. Option D is correct.
What is simplification?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,
when x = -4 and y = 4.
Expression = x⁶ - x/4y
Put x = -4 and y = 4.
= (-4)⁶ - [-4 /(4×4)]
= 4096 + 1/4
= 16385/4
Thus, the required simplified value of the given expression at x = -4 and y = 4 is 16, 385/4. Option D is correct.

Write an equation of the line that passes through (3, 7) and is parallel to the line shown. (1, 4) (- 2, - 2)
Answer:
y=2x+1.
Step-by-step explanation:
You first need to find the slope of the line already graphed. -2 to 1 would be three units to the right, and -2 to 4 would be six units up. You would use the equation (y2-y1)/(x2-x1), where x1 and y1 would be the x and y values of the first coordinate of the graphed line, and x2 and y2 would be the second coordinate. This would be 6/3, which can be simplified to 2/1, which can be simplified to 2, which would mean the slope of the given line would be 2, as well as the parallel line. Now, you could use a pretty complicated equation to find the y-intercept of the line you need to graph, but I would recommend using the slope to find it. Since the given point is (3, 7), you would need to go to the left, meaning you would reverse the slope until you reach the y-axis, so you would use -2 as the slope. 3*-2=-6, and 7-6=1, so the y-intercept would be 1. The answer would be y=2x+1. Hope this helps.
