Answer:
No, the pool will not fit.
Step-by-step explanation:
Radius of pool: 3.14 r^2= 379.94
Divide by 3.14: r^2= 121
Square root both sides: r=11
11>10, thus the pool won't fit.
Answer:
See below.
Step-by-step explanation:
Triangle ABC will be right-angled if 2 of its sides are perpendicular to each other. When sides are perpendicular the product of their slopes = -1.
Slope of side AB = (-3-2)/(2-5) = -5/-3 = 5/3
Slope of side BC = (3- -3) / -8-2) = 6/-10 = -3/5
The product of the slopes = 5/3 * -3/5 = -15/15 = -1.
So AB is perpendicular to BC and triangle ABC is right-angled .
Hello,
Let's
V1 the velocity of the 1st bricklayer,
V2 the velocity of the 2nd bricklayer,
1wall=V1*6==>V1=w/6
1wall=V2*4==>V2=w/4
==>V1+V2=w/6+w/4=10w*24=5w/12
Let's t the time for the 2 bricklayer to build the wall
(V1+V2)t=w
==>5w/12*t=w
==>t=12/5 (h)=2h24min.
X = adult
y = children
53(x+y=431)
53x +24y = 15390$
53x+53y = 22,843
subtract from
53x+24y = 15,390
29y = 7,453$
y = 257
53x + 24 (257) = 15,390
53x + 6,168 = 15,390
53x = 9,222
x = 174
