Answer:
it rise over run so put 2y on graph count down 4 and move right 1
Step-by-step explanation:
Area of the room = 14*15 = 210 ft^2
Cost padding = 210*89 = 186.90
Cost of carpet = 210 * 2.99 = 627.90
Perimeter of the room = 2*15 + 2*14 = 58 ft
Cost of strip = 58*0.19 = 11.02
Total cost of supplies = 186.90 + 627.90 + 11.02 = 825.82 Answer
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°
You need a common denominator in order to add/subtract fractions. for example:
1/4+3/2=?
1/4+6/4=7/4
what i did there was multiply 3/2 by 2/2 to get the denominator to equal 4. the reason it’s 2/2 is cause what you do to the bottom is what you do to the top.
3/2(2/2)= 6/4
Answer:
61.1% of high school student who took the SAT in 2015 will have a critical reading SAT score between 400 and 600 points.
Step-by-step explanation:
We are given the following information in the question:
Mean, μ = 495
Standard Deviation, σ = 116
We are given that the distribution of scores from the 2015 school year for high school students in the United States is a bell shaped distribution that is a normal distribution.
Formula:
P(SAT score between 400 and 600 points)
Thus, 61.1% of high school student who took the SAT in 2015 will have a critical reading SAT score between 400 and 600 points.
