Answer:
Clyde needs 2/3 cup more.
Step-by-step explanation:
The equation can be:
C = 2 - 2( 1 1/3 )
If Clyde is doubling the recipe, he will need 2 2/3 cups of flour. 2 2/3 minus 2 (the amount he has) will give you your answer.
Answer:
12 boys
Step-by-step explanation:
Multiply the ratio numbers by 6 and you have
boys : girls = 2 : 3 = 12 : 18
There are 12 boys in the class.
Answer:
Step-by-step explanation:
<h3>Given</h3>
- f(n) = n ^ 4 + 5n ^ 3 + 2n ^ 2 - 5n + 13
<h3>To find </h3>
<h3>Solution</h3>
<u>Substituting n with -2</u>
- f(-2) =
- (-2)^4 + 5(-2)^3 + 2(-2)^2 - 5(-2) + 13 =
- 16 - 40 + 8 + 10 + 13 =
- 7
Answer:
10 sculptures
Step-by-step explanation:
He makes 1 sculpture for every 5 paintings. We can break it down like this to simplify:
We know that if he made 50 paintings in total, thats 10 groups of five paintings (5x10=50)
For every group of 5 paintings, he makes one sculpture
So if there are 10 groups of five paintings, he made 10 sculptures.
The way tires on wheels work is that when the wheel turns one complete
turn, it moves (forward or backward) by a distance that's the circumference
of the tire.
Now, we know that the circumference of a circle is (π) times the diameter.
The diameter of the tire on this bus is 1 meter. So its circumference is
(π · 1 meter), and every time it turns once, the bus moves 1 meter down
the road.
If the tire rotated 8,000 times, then the bus moved 8,000π meters,
or 8π kilometers.
THAT's the exact answer. If you want to know how far that actually is,
then you take some number that's approximately π and multiply it by
8 km. You can never get an exact answer like that, because you can
never write the exact value of π with digits.
In school, we often use ' 3.14 ' for π . If you do that, then the bus
traveled
(8 km) x (3.14) = 25.1 kilometers .
When you do that, you have to remember that it's approximate.
If you want an exact answer, then you have to leave π in the answer.
