Answer:
40°
Step-by-step explanation:
The measure of the right angle is 90°.
The measures of the angles 10° and 2x add up to the measure of the right angle.
2x + 10° = 90°
2x = 80°
x = 40°
Answer: The amount of fencing needed can be expressed as 6x + 6 ft and, the cost of fencing can be expressed as Cost = 18x + 18
Step-by-step explanation: The dimensions of the rectangular garden are given as
Length = 2x + 3
Width = x
The amount of fencing that he would need is simply the total measurement all around the rectangular garden, that is, the perimeter. The perimeter of a rectangle is given as follows;
Perimeter = 2(L + W)
With the dimensions already provided we can now substitute for the values
Perimeter = 2(2x + 3 + x)
Perimeter = 2(3x + 3)
Perimeter = 6x + 6
Therefore the amount of fencing needed can be written out as,
6x + 6 ft
If however, fencing costs $3 per foot, then the cost of the entire fencing can be expressed as
Cost = 3(6x + 6)
Cost = 18x + 18
Answer:
<h2>k = 3</h2>
Step-by-step explanation:
y = kx² - 3x
Since the points lie on the graph we can substitute the values of x and y that's
( 2 ,6) into the equation to find k.
We have
6 = (2)²k - 3(2)
6 = 4k - 6
4k = 6 + 6
4k = 12
Divide both sides by k
That's
We have the final answer as
<h3>k = 3</h3>
Hope this helps you
Answer:
87.3
The answer to get 87.3 is to see if the number in the hundredths place (this case 1) is bigger or the same as the value of 5. If it is round the tenth up but if not then cut the rest of the numbers off.
Answer:
Part A : About 5,931
Part B : 5,930.8
Part C : Yes, because it rounded it to the nearest full number
