Answer:
45 cubic units
Step-by-step explanation:
Vtotal = 1/2 (2.5*3) * 6 *2
where
2.5 is the base
3 is the height
6 is the length
2 is the number of prisms
Answer:
530.66 in.²
Step-by-step explanation:
Area of a circle = πr²
In the circle above, the diameter is given. To find the radius, you divide the diameter by 2, i.e.
Radius(r) = 
= 13 in.
∴Area of the circle = 3.14 × 13²
= 3.14 × 169
= 530.66 in.²
Hope this helps :)
Let's convert the word descriptions into mathematical equations first for illustration.
f(x) = x^2 - x - 12
g(x) = -2.5x - 2
Then, we equate g(x) and f(x). The final equation becomes
x^2 - x - 12 = -2.5x - 2
Then, we simplify by transposing and combining like terms.
x^2 - x + 2.5x -12 + 2 = 0
x^2 + 1.5x - 10 = 0
Since this is a quadratic equation, we find the roots by using the quadratic formula
where a = 1, b = 1.5 and c=-10
Thus, the answer is x = 2.5, -4.
20×3 is 60 and if Sarah counted 45 beats in 20 seconds you'd multiply 45 by 3 so it would be 135.
Raising 4,929 to the place value of the underlined digit will give a value of 4930.
<h3>What is rounding up of numbers?</h3>
It should be noted that rounding up of numbers simply means raising the number to the nearest ten, hundred, or thousand.
In this case let's assume that the underlined number is 2. Therefore, raising 4929 will give 4940. It should be noted that the number beside it is more than 5. Therefore, 1 will be added to 2 making 3. The new number is 4930.
