Samuel could round both of the individual numbers, to get s rounded answer. So, he could round 23 to 20, and 395 to 400, to get a product of 8000.
Or, he could multiply the numbers first, so 23*395 to get a product of 9085, which would then round to 9000, or depends on what place value it would want to be rounded to.

2. Given &lt; MCP = 65°, find the measurement of arc MP , arc MRP and &lt; MRP.​
iren2701 [21]

▪▪▪▪▪▪▪▪▪▪▪▪▪  {\huge\mathfrak{Answer}}▪▪▪▪▪▪▪▪▪▪▪▪▪▪

We know that the Angle subtended by an arc on centre of the circle is double as that of Angle subtended by the same arc on the circumference (boundary) of the circle

So,

  • \sf \angle MCP =  2\angle MRP

  • \sf65 \degree = 2 \angle MRP

  • \sf\angle MRP = 65 \degree \div 2

  • \sf\angle MRP = 32.5 \degree

What is the value of 7(x+4)² - 3x when x = 2?
sdas [7]

Answer:  the value of 7x-y is -14.

Step-by-step explanation:

When x=2 and y=4,

To find the value of 7x - y when x =2, y = 4, this means when ever you see x, put 2 in replacement, y, put 4 respectively.

7x - y = 7(2 - 4)

14 - 28

= -14.​

An above-ground swimming pool in the shape of a cylinder has a diameter of 18 feet and a height of 4.5 feet. If the pool is fill
laila [671]

The volume of a cylinder is

                                   (pi) (radius²) (height) .

Radius = 1/2 diameter.
Radius of this pool = (1/2) (18 ft) = 9 ft

The pool is a cylinder with height of 4.5 feet. 
The water in it is also a cylinder, but only 4 ft high.

Volume of the water =

             (pi) x (radius²) x (height)

         =  (pi)  x  (9 ft)²  x  (4 ft)

         =  (pi)  x  (81 ft²)  x  (4 ft)

         =  (pi)  x  (324 ft³)  =  1,017.9 ft³ .
