Answer:
i say 40 minutes
Step-by-step explanation: in the first 4 minutes she planted 7 flowers, in the next 8 minutes she planted 21 flower. so what i did was divide 70 by 7... since the amount of flowers is going up by 7's. so 70 divided by 7 is 10... now every 4 minutes you plant flowers so 10 by 4= 40 minutes
Answer: Quadratic
Solution
X=0
X=- 1/3
Option B. 55° is the correct answer
Step-by-step explanation:
"The sum of interior angles of a triangle is always 180°"
Given
m∠A=(3x+1)°
m∠B=(2x-1)°
m∠C = 40°
We know that
m∠A+m∠B+m∠C=180°
Putting the values of angles
![(3x+1) +(2x-1) +40 = 180\\3x+1+2x-1+40 = 180\\5x+40=180\\](https://tex.z-dn.net/?f=%283x%2B1%29%20%2B%282x-1%29%20%2B40%20%3D%20180%5C%5C3x%2B1%2B2x-1%2B40%20%3D%20180%5C%5C5x%2B40%3D180%5C%5C)
Subtracting 40 from both sides
![5x+40-40=180-40\\5x=140](https://tex.z-dn.net/?f=5x%2B40-40%3D180-40%5C%5C5x%3D140)
Dividing both sides by 5
![\frac{5x}{5} = \frac{140}{5}\\x=28](https://tex.z-dn.net/?f=%5Cfrac%7B5x%7D%7B5%7D%20%3D%20%5Cfrac%7B140%7D%7B5%7D%5C%5Cx%3D28)
We have to find Angle B,
So
m∠B = 2x-1 = 2(28)-1 = 56-1 = 55°
Hence,
m∠B=55°
Option B. 55° is the correct answer

The correct answer is d, i just graphed all four
Let last year product be
x boxes.
110% of x means
![\displaystyle{ \frac{110}{100}\cdot x](https://tex.z-dn.net/?f=%5Cdisplaystyle%7B%20%20%5Cfrac%7B110%7D%7B100%7D%5Ccdot%20x%20)
.
Thus, we solve the equation:
![\displaystyle{ \frac{110}{100}\cdot x=715,000](https://tex.z-dn.net/?f=%5Cdisplaystyle%7B%20%5Cfrac%7B110%7D%7B100%7D%5Ccdot%20x%3D715%2C000)
.
Multiplying both sides by
![\displaystyle{ \frac{100}{110}](https://tex.z-dn.net/?f=%5Cdisplaystyle%7B%20%5Cfrac%7B100%7D%7B110%7D)
, we have:
![\displaystyle{ x=715,000 \cdot \frac{100}{110}=650,000](https://tex.z-dn.net/?f=%5Cdisplaystyle%7B%20x%3D715%2C000%20%5Ccdot%20%5Cfrac%7B100%7D%7B110%7D%3D650%2C000)
.
