Since multiplicative inverse is the same thing as reciprocal, the multiplicative inverse is just the denominator and the numerator flipped. So the multiplicative inverse of -7/9 is 9/-7. Hope this helps! If you ever need any more help in math you could always DM me.
D because rational numbers CAN be negative
Answer:
1271.7in
Step-by-step explanation:
A complete rotation is = circumference of the wheel.
So calculate the circumference which is pi times diameter.
27 times pi (which is 3.14) = 84.78in one rotation
so if you make 15 rotations, you are multiplying it by 15
15 x 84.78 = 1271.7in
Answer:
Step-by-step explanation:
P=2(L+W), we are given a side of 20 and a side of b
P=2(20+b)
P=40+2b
A) P(6)=40+12=52ft TRUE
B) P(8)=40+16=56ft TRUE
C) P(10)=40+20=60ft FALSE
D) P(12)=40+24=64ft FALSE
E) P(11)=40+22=62ft FALSE
So only A and B are true
Answer:
122 in²
Step-by-step explanation:
Applying,
S.A = bh+ bl+bl+bl............. Equation 1
Where S.A = Surface area of the prism, b = base of the triangle, h = height of the triangle, l = lenghth of the prism
From the question,
Given: b = 4 in, h = 3.5 in, l = 9 in
Substitute these values into equation 1
S.A = 4×3.5+9×4+9×4+9×4
S.A = 14+108
S.A = 122 in²
Hence the surface area of the prism is 122 in²
