If the box if cubed for volume then lbh is 25x25x100=62500 cm ^3...if that's right. hope it helps any.
Answer:
x+0.05x=3.15 which has one solution
Step-by-step explanation:
Complete question below:
Joshua sells a pack of pens for 3.15 which is 5 percent more than he pays for them. which equation will help find x, the amount he pays for a pack of pens? how many solutions will this equation have? x+0.05x=3.15, which has infinitely many solutions x+0.5x=3.15, which has one solution x+0.05×=3.15 which has one solution 0.05×=3.15, which has no solution
Let
x= the amount Joshua pays for a pack of pen
5% of x more than he paid for them
=0.05x more
Buying price=0.05x + x
Selling price=3.15
Equate buying and selling price
0.05x + x = 3.15
1.05x=3.15
Divide both sides by 1.05
1.05x / 1.05 = 3.15/1.05
x=3
The equation is 0.05x+x=3.15
The answer is:
x+0.05x=3.15 which has one solution
X^2 + y^2 -4x27 (the numbers in bold means the multiplying a negative and a positive equals a negative)
x^2 + y^2 -(4x27) = x^2 + y^2 -108
Answer:
B) 1/4 × 3/6 = 3/24
Step-by-step explanation:
1/4 of the rectangles are colored blue(ish).
3/6 of the rectangles are colored yellow(ish).
The colors overlap in 3/24 of the rectangles.
The problem statement with these numbers in it is that of choice B.
The function is ![y = (x +2)^2 + 5.](https://tex.z-dn.net/?f=y%20%3D%20%28x%20%2B2%29%5E2%20%2B%205.)
we use the vertex form of the quadratic equation
We have given a graph,
<h3>What is the vertex form of the quadratic equation?</h3>
y = a(x - h)^2 + k.
Therefore the vertex of the given graph is
See the vertex at (-2, 5)
Since the general way to write the vertex is (h, k), we compare (h, k) to (-2, 5).
![y = a(x - (-2))^2 + 5.\\y=a(x+2)^2+5......(1)](https://tex.z-dn.net/?f=y%20%3D%20a%28x%20-%20%28-2%29%29%5E2%20%2B%205.%5C%5Cy%3Da%28x%2B2%29%5E2%2B5......%281%29)
Now we have given that (-4,1) use this value in the above equation so we get,
![(1)=a(-4+2)^2+5](https://tex.z-dn.net/?f=%281%29%3Da%28-4%2B2%29%5E2%2B5)
![1=a(-2)^2+5](https://tex.z-dn.net/?f=1%3Da%28-2%29%5E2%2B5)
![1=4a+5](https://tex.z-dn.net/?f=1%3D4a%2B5)
![1-5=4a](https://tex.z-dn.net/?f=1-5%3D4a)
![-4=4a](https://tex.z-dn.net/?f=-4%3D4a)
![a=-4/4](https://tex.z-dn.net/?f=a%3D-4%2F4)
![a=-1](https://tex.z-dn.net/?f=a%3D-1)
Using the value of an in equation (1) we get,
Therefore the function is ![y = (x +2)^2 + 5.](https://tex.z-dn.net/?f=y%20%3D%20%28x%20%2B2%29%5E2%20%2B%205.)
