At $7.50 per soccer ball, they earn a daily profit of $232.50.
The store needs to earn a daily profit of $400 – $232.50 = $167.50 from footballs.
Solve 167.50 = –4x2 + 80x – 150 to find the price for footballs: x = $5.46 and $14.54.
45 is 75% of what?
45 is 75% of X
Equation: Y = P% * X
Solving our equation for X
X = Y/P%
X = 45/75%
Converting percent to decimal:
p = 75%/100 = 0.75
<span>X = 45/0.75 </span>
<span>X = 60

Answer:-2,7
Step-by-step explanation:
Answer:
This is a 45, 45, 90 triangle.
That means, x is equal to 12, since all 45, 45, 90 triangles are also isosceles, meaning that two of their sides are equal to each other.
To solve for y, we can use the Pythagorean theorem:
12^2 + 12^2 = y^2
288 = y^2
y=12

Answer: x = 12 degrees.
Step-by-step explanation:
The triangle ABC is a right triangle, which means that it has a right angle of 90 degrees.
This is represented by the small square on the bottom-left corner of the triangle.
The angle DBC is 78 degrees. There is also the angle of ABD, which is represented by X.
The right angle is equivalent to 78 degrees and x. You can represent this in an equation, where the sum of 78 degrees and x = 90 degrees, the right angle:
78 + x = 90
x = 12
