Inverse Operation of Multiplication.
Answer:
Area of floor = 21.6m2
area of tile = 576cm2=0.0576m2
now,
number of tiles = 21.6/0.0576
= 375
Hey there!!
perimeter of rectangle = 2 ( l + b )
perimeter of a triangle = add up all the sides
2 ( x + 2 + x + 1 ) = x + 7 + x + 3 + x + 9
2 ( 2x + 3 ) = 3x + 19
4x + 6 = 3x + 19
x = 19 - 6
x = 13
Hope my answer helps!
Answer:
y=4x+13 or y-5=4(x+2)
Step-by-step explanation:
we know that
The equation of the line into point slope form is equal to
y-y1=m(x-x1)
In this problem we have
m=4
(x1,y1)=(-2,5)
substitute
y-5=4(x+2) ----> equation of the line into point slope form
Convert to slope intercept form
y-5=4x+8
y=4x+8+5
y=4x+13 ----> equation of the line into slope intercept form
The formula is
I=prt
I interest earned?
P principle 70
R interest rate 0.3
T time 2.5 years
I=70×0.3×2.5
I=52.5
