Answer:
She drove 3 hours
Step-by-step explanation:
Leslie drove 2/3 of the 4 1/2 hours trip. To determine how long she drove, multiply these numbers together.
2/3 * 4 1/2
We need to change the second number to an improper fraction
4 1/2 = (2*4 +1)/2 = 9/2
2/3 * 9/2 = 9/3 = 3
She drove 3 hours

Answer:
1512 cm³
Step-by-step explanation:
Formula
Volume of right rectangular prism = Length × Breadth × Height
As given
Two blocks of wood are shaped as right rectangular prisms.
The smaller block has a length of 9 cm, a width of 3 cm, and a height of 7 cm.
As given
The dimensions of the larger block are double the dimensions of the smaller block.
Length of the larger block = 2 × Length of the smaller block
= 2 × 9
= 18 cm
Breadth of the larger block = 2 × Breadth of the smaller block
= 2 × 3
= 6 cm
Height of the larger block = 2 × Height of the smaller block
= 2 × 7
= 14 cm
Put in the formula
Volume of larger wooden block = 18 × 6 × 14
= 1512 cm³
Therefore the volume of the wooden block is 1512 cm³ .
Since we know a square has 4 equal sides
and is equal to to exact right triangles.
USing the formula for Perimeter
l+l+w+w=P or 2L+2W=P
56cm÷4=14 so now we have
(2)14+(2)14=P
P=14cm^2
The slant length on a triangle is equal to L
Slant lenght=14
