Answer:
78 ft squared
Step-by-step explanation:
To find the area of trapezoid, we could use this formula:
.5*height*(sum of bases)
We know both the base lengths. They are 10 and 16 ft.
The height can be found by looking at that right triangle whose base is (16-10) ft or 6 ft.
So we want to find the height which is opposite the 45 degree angle and we have the adjacent side's measurement of 6ft.
This has the tangent ratio written all over it since tangent of an angle is opposite side's measurement over adjacent side's measurement.
tan(45)=height/6
1=height/6
6=height
6ft=height
The answer is:
.5*height*(sum of bases)
.5*6 ft*(10 ft+16 ft)
3 ft(26 ft)
78 ft squared
Note: That one right triangle is an isosceles right triangle so we didn't need trigonometry.
Given :
Money Katie has, M = $30.
She has found a bracelet with a regular price of $45 and a discount of 35%.
The sales tax is 7%.
To Find :
Will she have enough to buy the bracelet.
Solution :
Original price = $45 .
Price after discount = $( 45 - 45×0.35) = $29.25 .
Selling Price = $( 29.25 + 29.25×0.07 ) = $31.2975 .
Since, selling price is greater than $30.
Money needed = $( 31.2975 - 30 ) = $1.2975 .
Therefore, Katie will not buy the bracelet.
Answer:
Sweetie, it's easy. Let me explain.
The slope formula is (y2 - y1) (x2 - x1) you find the slope by putting the rise over the run. For example, if the point goes up 2 and right 3 your slope would be (2,3) and let's just say your next coordinate is (4,5) you would take the y, 5, from the second coordinate and subtract it by the y from the first coordinate, 3. So you would have 2 and you do the same with the x values. So your slope would be 3/2. Hope I helped at all.
Step-by-step explanation:
In this case, it is a (-infinity, +infinity)
In this case, y can assume any number, negative or positive, and for all values of x, the number can be squared and subtracted from
Answer:
3/50 of a gallon
Step-by-step explanation:
50 / 1 = 3 / x
cross-multiply:
50x = 3
x = 3/50
