Answer:
Step-by-step explanation:
563 people / 15 classes= 37 8/15. They should offer 38 classes.
2146 questions in 45 weeks.
2146/45= 47 31/45. round to 48 questions a week.
I would choose the first one. Even though the 2000 is an underestimate, the 50 weeks is overestimate , when divided it comes out to 50 questions a week which is closer to the 48 it actually is. I'd rather write too many questions then not enough.
Answer:
2 < x < 3
Step-by-step explanation:
4x - 4 < 8 AND 9x + 5 > 23
4x < 12 AND 9x > 18
x < 3 AND x > 2 so the answer is 2 < x < 3.
Answer:
Step-by-step explanation:
add 14.52 to both sides of the inequality to cancel that value out from the middle. Then you can divide both sides by 3x to get x by itself in the middle.
Answer:
3. 294 m²
4. 185,856 mm²
Step-by-step explanation:
To find the surface area of any figure, you can simply find the sum of the areas of all the sides. In question 3, the figure is a triangular prism that has two triangular bases and three rectangular sides. The measurements for the triangles are b = 9m and h = 6m. The formula for the area of a triangle is base times height divided by 2, or 9 x 6 = 54/2 = 27 m². However, since there are two triangular bases, the area for both is 54 m². The measurements for the other three rectangles are given:
7(10) + 8(10) + 9(10) = 240 m² + 54 m² = 294 m²
The surface area of a cube is much easier since all sides are equal and can be found using the formula:
SA = 6s², where 's' represents the measure of a side.
SA = 6(176)² = 185,856 mm²
Answer:
(1,5)
Step-by-step explanation:
You use the midpoint formula to solve this problem
The midpoint formula:
To solve for x: (x1+x2)÷2
To solve for y: (y1+y2)÷2
