Answer:
15m+5n
Step-by-step explanation:
5(3m+n) In this case you need to multiply. 5x3m is 15m; 5xn is 5n. 15m+5n
Answer:
-5 5/10, -32/40,5
whenever a number has a negative sign,the larger the number the smaller.
i.e (-55/10= -5.5) is smaller than -32/40=-0.8 and then the greatest is 5 since it is a positive number and positive numbers are greater than negative numbers.
Answer:
98
Step-by-step explanation:
the measure of angles of a triangle=180
the measure of straight angle=180 find angle HAC:
180-128=52
angle A: 180-52-46= 82
now find IAC : 180-82=98 degrees
See my diagram
I'm assuming that your swimming pool is an oval or something like that
remember that the area of an oval is r₁r₂π where r₁ and r₂ are the 2 radii
so
we must do big oval-small oval
the radius is half of the diameter
calculating smalller oval area
it is 32 by 18
those are diameter
halve them
16 by 9
so the area is 16*9*pi or 144pi square feet
big oval area
add 3 feet to each side, so 6 feet total to each dimention
the big oval has diameters of 32+6 and 18+6 or 38 and 24
halve them to find the radii
19 and 12
the area is 19*12*pi or 228pi
so the area that is concrete=228pi-144pi=84pi squaer feet or about 263.89 square feet
