how many rectangular prism can you make out of 20 snap of cubes
-21, - 13, -5, 3, ...
Find a23
a(n)=a(1)+(n-1)×d
a(23)=-21+(23-1)×8
a(23)=-21+(22)×8
a(23)=-21+176
a(23)=155
And we're done....

Answer:
The probability that a typical customer buys both gasoline and groceries, P(Ga n Gr) = 0.1955
Step-by-step explanation:
Let the probability that a customer guys groceries be represented by P(Gr) and that of buying gasoline be P(Ga)
Given
P(Gr) = 0.76
P(Ga) = 0.23
P(Gr|Ga) = 0.85
For mutually exclusive events,
P(B|A) = (P(B n A))/P(A)
P(Gr|Ga) = (P(Gr n Ga))/P(Ga)
P(Gr n Ga) = P(Gr|Ga) × P(Ga)
P(Gr n Ga) = 0.85 × 0.23 = 0.1955

Answer:
Volume
Figure 1 = 56 cube units
figure 2 = 60 cube units
figure 3 =72 cube units
Surface area
Figure 1 = 100 square units
figure 2 = 104 square units
figure 3 =108 square units
Step-by-step explanation:
From the all figure we can see that each figure made up of unit cubes
Figure 1
Surface area
Large cuboid portion =2 x (6 x 2 ) + (6 x 4) + 2 x(4 x 2) + 16
= 24 + 24 + 16 + 16 = 80 unit square
Small cuboid portion = (4 x 2) + (2 x 2) + (4 x 2) = 8 + 4 + 8 = 20
Total surface area = 80 + 20 = 100 unit square
Volume
Small cuboid = 4 x 2 = 8
Large cuboid = 6 x 4 x 2 = 48 cube unit
Total volume = 48 + 8 = 56 cubs units
Figure 2
Surface area
Total surface area =24 + 18 + 36 + 20 + 6 = 104 unit square
Volume
Small cuboid = 6 x 2 = 12
Large cuboid = 6 x 4 x 2 = 48 unit square
Total volume = 48 + 12 = 60 cube units
Figure 3
Surface area
Total surface area = 48 + 36 + 24 = 108 square units
Volume
Total volume = 6 x 4 x 3 = 72 cube units
5.4*10^-1
that's the answer in scientific notation
