4(2r - 1) = -2(3r + 16)...distribute thru the parenthesis
8r - 4 = -6r - 32
8r + 6r = -32 + 4
14r = - 28
r = -28/14
r = -2 <===
Ok so...
You want to move the decimal point to the right until the number is greater than 1 but less than 10.
The number will end up being 5.2
You moved the decimal point 3 times to the right.
So it will be 5.2 x 10^-3. It is negative because you moved it to the right. The exponent would be positive if you moved it to the left
Answer:
The correct answer is option d. 576 ft^2
Step-by-step explanation:
From the figure we can see that a prism
<u>To find the surface area</u>
Surface area = Base area + area of 2 triangles + Two side area
Base area = length * breadth = 15 * 12 = 180 ft^2
Area of triangle = bh/2 = (12 * 8)/2 = 48 ft^2
Area of two triangle = 48 * 2 = 96 ft^2
Area of one side = 15 * 10 = 150 ft^2
Area of two side = 2 * 150 = 300 ft^2
Surface area = 180 + 96 + 300 = 576 ft^2
The correct answer is option d. 576 ft^2
Answer:
She needs $8 more to buy a game that cost $45
Step-by-step explanation:
10 * 2 = 20
5 * 3 = 15
1 * 2 = 2
20+15+2 = 37
45-37 = $8
She needs $8 more to buy a game that cost $45
