Answer:
∠1 = 47
∠2 = 63
∠3 = 70
∠4 = 70
Step-by-step explanation:
∠2 and 63 are alternate interior angles. Alternate interior angles are equal.
∠2 = 63
∠3 and 110 are linear pair angles. Sum of linear pair angles is 180.
∠3 + 110 = 180
∠3 = 180 - 110
∠3 = 70
GDEF is a parallelogram, so ∠DGF = ∠DEF
That is,
∠3 = ∠4
∠4 = 70
∠1, ∠2 and ∠3 are interior angles in a triangle.
Sum of interior angles in a triangle is 180,
∠1 + ∠2 + ∠3 = 180
∠1 + 63 + 70 = 180
∠1 + 133 = 180
∠1 = 180 - 133
∠1 = 47
Answer:
1 kilometer in 1 hour
Step-by-step explanation:
unit rate is km(kilometer) per hour(hr)
1/3 km = 1/3 hr
multiply both sides by 3
1 km in 1 hour
Step-by-step explanation:
A.) Ok, so the mean price for Southtown is 72,800.
And the mean price for middle town is 54,900
So Southtown has the higher mean price.
Explanation:
To find the mean. You must first add up all the numbers, then divide the total by how many numbers you added up.
72,000 + 50,000 + 68,000 + 93,000 + 81,000 = 364,000
Then,
364,000/ 5 = 72,800
B.) It is 17,900
Explanation:
72,800 - 54,900 = 17,900
Hope this helps you out!!! : )
Answer: A
Step-by-step explanation:
The <em><u>correct answers</u></em> are:
substitution property; subtraction property of equality; division property of equality; and reflexive property.
Explanation:
The difference between the given statement and the first statement is that 11x is replaced with 88. This is because we are told that x=8; 11(8) = 88. Substitution has been used here.
The difference between the first step and the second step is that 88 is no longer on the left hand side and the right hand side is -89. This is because to cancel 88, it has been subtracted from each side of the equation. This is the subtraction property of equality.
The difference between the second step and the third step is that -6 is no longer on the left side and the right hand side is 89/6. This is because to cancel -6 both sides were divided by -6. This is the division property of equality.
The difference between the third step and the last step is that the 89/6 and y have been flipped around the equals sign. This is the reflexive property.
