Answer:
Step-by-step explanation:
The end behavior of this function is the same as that of y = -x^2: the graph starts in Quadrant III and continues in Quadrant IV; the shape is roughly that of an upside-down parabola.
Answer:
n, h = Naomi's and Hudson's work hours, respectively
n + h = 13
35n +20h = 395
Step-by-step explanation:
We are asked for the number of work hours of Naomi and Hudson. It is convenient to define the variables n and h to represent those hours, respectively. Then the system of equations is ...
n + h = 13 . . . . . . . . . . . . total work hours
35n +20h = 395 . . . . . . total shirts ironed
_____
The solution is Naomi worked 9 hours; Hudson worked 4 hours.
Answer:
m∠K = 97°
Step-by-step explanation:
The sum of the measures of the angles of a quadrilateral is 360
127 + 5x + 3 + 10x + 7 + 88 = 360
15x + 225 = 360
15x = 135
x = 9
m∠K = 10x + 7 = 10(9) + 7 = 90 + 7 = 97°
Answer:
1. 11/4
2. 19 1/4
Step-by-step explanation:
To change into an improper fraction:
((2 times 4)+3)/4
=11/4
To calculate total distance:
(11/4) times 7
=77/4
=19 1/4
Answer:
21.46 cm²
Step-by-step explanation:
because the question want only for the SHADED REGION but NOT AREA OF THE SQUARE
(if we just multiply 10x10. you will get the area of a square which is hundered)
To find the shaded region:
1. area of a circle is πr² (we have 4 circle there)
2. Find the area of all circle
# how do we know the radius?
- half of 10 is 5
- 5 is the diameter of each circle
- the radius is half of 5 which is 2.5
- π(2.5)² = 25/4π (area of 1 circle)
3. since we have 4 circle then, 25/4π x 4 = 25π
4. the area of the square is 100cm²
5. we want the shaded region so we have to minus the area of the circle
6. 100 - 25π (use your calculator to find the answer)
answer should be 21.46 cm²
(hope this helps)
