Answer:
I'm sorry there is not enough information to answer this question
Step-by-step explanation:
A. The equation is in the form of y = mx + b. It will be y = -3x + 30.
B. The y-intercept is 30, which is the starting temperature in the problem.
C. The slope is -3, which means that they temperature is falling by 3 each hour.
Answer: 64 daisies
Step-by-step explanation:
8 x 4 = 32 8 x 8 = 64 daisies
For this problem we can use a proportion to solve.
Set up the proportion.
Cross multiply.
Divide.
So, it would cost $13,200 to have a 1,100 square foot roof installed.
Answer:
1. DB = 10 as diagonals of isosceles trapezoid are congruent
2. ∠DAB and ∠BCD are supplementary angles
- m∠BCD = 180° - 120° = 60°
3. ∠BCD is congruent with ∠ADC as trapezoid is isosceles
4. AB = 15, DC = 25,
- EB = 1/2(AB + DC) as midline
- EB = 1/2(15 + 25) = 20
5. m∠ADC = 2x - 10, m∠ABC = 3x + 40
<u>These are supplementary, find x first:</u>
- 2x - 10 + 3x + 40 = 180
- 5x + 30 = 180
- 5x = 150
- x = 30
- m∠BCD = m∠ADC = 2*30 - 10 = 50°
