The correct answer is A because the line goes down left and up right.....choice B is a horizontal line which means it has a zero slope......choice C is a negative slope because it goes down right and up left.
Answer:
RPQ = 239°
Step-by-step explanation:
Since SP is a straight line going through the center of a circle, it is a diameter.
We can say that m<SOR and m<ROP are supplementary and add up to 180° because they form a straight line. We can set up an equation:
m<SOR + m<ROP = 180°
We can substitute in the value of m<SOR:
31° + m<ROP = 180°
m<ROP = 149°
Next, we can also say that m<SOQ and m<QOP are supplementary because they form a straight line. Also, since QO is perpendicular to SP, we can say that both m<SOQ and m<QOP equal to 90°.
Now, we can say that m<ROQ (reflex angle) is equal to the sum of m<QOP and m<ROP from angle addition postulate. We can write the equation:
m<ROQ = m<QOP + m<ROP
m<ROQ = 90° + 149° = 239°
The reflex angle <ROQ cuts the arc RPQ, so they would have the same measure. So, arc RPQ = 239°
Answer: p=400
Step-by-step explanation: Divide 320 by 0.8. =40 0.8=1/10 of 8. Multiply 40 by 10. p=400
Answer:
7 sheets
Step-by-step explanation:
Dimension of gabble = 42' by 5'
Dimension of standard plywood sheet : 4' by 8'
Area that will be covered by gabble :
Length * width :
42 * 5 = 210 in²
Area covered by 1 plywood sheet :
4 * 8 = 32 in²
Number of plywood sheets required :
Area of gabble / Area of 1 plywood sheet
210 in² / 32 in²
= 6.5625
This means the number of plywood sheets that will be required is 7
