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

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

Item 5 A bag contains 6 red marbles. The ratio of red marbles to blue marbles is 2 for every 5. Find the number of blue marbles in the bag. Item 5 A bag contains 6 red marbles. The ratio of red marbles to blue marbles is 2 for every 5. Find the number of blue marbles in the bag.
Answer:
15 blue marbles
Step-by-step explanation:
Given that:
A bag contains 6 red marbles.
The Ratio of red to blue marbles is 2:5
Thus, the ratio of red marbles for 6 red marbles in a bag will be = 6/2 = 3
Now; the ratio of blue marbles in a bag containing 6 red marbles = 3 × 5 = 15 blue marbles
OR
Mathematically;
[tex]\dfrac{2}{5} \times \dfrac{x}{x} = \dfrac{6}{blue}[/tex]
So, we are looking for the same number we can multiply for both the numerator and the denominator that can give us the value of 6 in the above numerator to determine the value of the denominator. If we use 3 since 2× 3 = 6
We have:
[tex]\dfrac{2}{5} \times \dfrac{3}{3} = \dfrac{6}{blue}[/tex]
[tex]\dfrac{2}{5} \times \dfrac{3}{3} = \dfrac{6}{15}[/tex]
So, there are 15 blue marbles in the bag.
A hot tub pump circulates 3.9 cubic feet of water per minute.how many cubic inches of water does it circulate each second
Answer:
0.78 cubic inches/sec
Step-by-step explanation:
you take 3.9 cubic feet and multiply it by 12 to convert it into inches and you get 46.8 cubic inches. then you divide by 60 to convert minutes to second and you get 0.78. hope that helps
Answer:
1123.2 cubic inch per second
Step-by-step explanation:
3.9 feet^3 = per minute
? = second
39 = 60 sec
? = 1 sec
39/60 =0.65 feet cubic
1 cubic foot = 1728 cubic inch
0.65 feet cubic = ?
0.65 * 1728
= 1123.2 cubic inch

Answer:
B: 22.5 degrees
Step-by-step explanation:
The interior angles of a pentagon add up to 540 degrees
(if you dont believe me you can turn a pentagon into three triangles, 3x180 = 540)
So you have four same angles say measure "x" degrees, and one final one that measures "5x" degrees, so 9x = 540, and x = 60
Unless I read the problem wrong, 60 degrees is the answer which is not an option :P
Edit: Yea I read it wrong, the final angle is 5 times the other four angles COMBINED, so that angle measures "20x" degrees.
The total would be 24x = 540, and so x = 22.5

Please help me ASAP
Answer: 25
Step-by-step explanation:
5. Find the magnitude of 4i + 3j
Answer:
5Step-by-step explanation:
The magnitude of the complex number is expressed as;
|z| = √x²+y²
Given the complex number z = 4i+3j, x = 4 and y = 3
Substitute
|z| = √x²+y²
|z| = √3²+4²
|z| = √9+16
|z| = √25
|z| =5
Hence the magnitude is 5
The ratio of girls to boys in a class is 3:2. There are 25 students in this class. How many are girls and how many are boys? REPOST FOR ATTENTION
Answer:
15:10
Step-by-step explanation:
consider the starting point: we have 3 bots and 2 girls. this gives a total count of 5 so we need to see how many lots of 5 will fit into 25. 5 lots of 5 gives 25 so we have 5 lots of the ratio 3:2 Method: 5 lots of 3:2: 5 x (3:2)=(5 x 3):(5 x 2)= 15:10

Answer:
B, C, F
Step-by-step explanation:
B- has different lengths for each side and different angles
C-has different lengths for each side and different angles

Non congruent triangles means if shape is reflected or rotated they would not look the same. Congruent triangles have same equal length and angles are equal in measure.
There are 3 islands A,B,C. Island B is east of island A, 8 miles away. Island C is northeast of A, 5 miles away and northwest of B, 7 miles away. What is the bearing needed to navigate from island B to C? Round to the nearest degree
Answer:
[tex]B = 38[/tex]
Step-by-step explanation:
This question can be illustrated using the attachment and the required bearing will be calculated using cosine theorem;
[tex]b^2 = a^2 + c^2 - 2ac\ CosB[/tex]
In this case:
[tex]b = 5[/tex]
[tex]a = 7[/tex]
[tex]c = 8[/tex]
[tex]<B = ??[/tex]
Substitute these values in [tex]b^2 = a^2 + c^2 - 2ac\ CosB[/tex]
[tex]5^2 = 7^2 + 8^2 - 2 * 7 * 8\ CosB[/tex]
[tex]25 = 49 + 64 - 112\ CosB[/tex]
[tex]25 = 113- 112\ CosB[/tex]
Collect Like Terms
[tex]25 -113=- 112\ CosB[/tex]
[tex]-88=- 112\ CosB[/tex]
Divide through by -112
[tex]\frac{-88}{-112}= \frac{- 112\ CosB}{-112}[/tex]
[tex]\frac{-88}{-112}= CosB[/tex]
Reorder
[tex]Cos\ B = \frac{-88}{-112}[/tex]
[tex]Cos\ B = 0.7857[/tex]
Take arccos of both sides
[tex]B = cos^{-1}(0.7857)[/tex]
[tex]B = cos^{-1}(0.7857)[/tex]
[tex]B = 38[/tex] --- (approximated)
Hence, the bearing is approximately 38 degrees
Select the correct answer. A model rocket was launched from the top of a building. The rocket's approximate height can be modeled by the quadratic equation h = -4.9t2 + 53.9t + 127.4, where h is the rocket's height, in meters, after t seconds. When factored, this equation is h = -4.9(t - 13)(t + 2). What is a reasonable time for it to take the rocket to land on the ground? Answer A 11 seconds Answer B 13 seconds Answer C 2 seconds Answer D 15 seconds
Answer:
13 seconds.
Step-by-step explanation:
Given
[tex]h = -4.9(t - 13)(t + 2).[/tex]
Required
Determine a reasonable solution for t
To do this, we equate h to 0.
[tex]h = -4.9(t - 13)(t + 2).[/tex] becomes
[tex]0 = -4.9(t - 13)(t + 2).[/tex]
Divide through by -4.9
[tex]0 = (t - 13)(t + 2).[/tex]
Reorder the expression
[tex](t - 13)(t + 2) = 0.[/tex]
Split
[tex]t-13 = 0[/tex] or [tex]t + 2 = 0[/tex]
This gives:
[tex]t = 13[/tex] or [tex]t = -2[/tex]
But time can't be negative, So:
[tex]t = 13[/tex]
