Answer:

75.39 ft²

Step-by-step explanation:

The formula to the circumference of a circle is 2π·r

To get the radius of a circle we need to divide the diameter of the circle by 2

24÷2=12

Now we input the numbers into the formula

2π·12=

6.28·12=75.39ft²

Therefore, the circumference of the circle is 75.39 ft², respectively.

Maria used one bag of flour. She baked
Vitek1552 [10]

Answer:

Answer is 11.

Step-by-step explanation:

Maria used two loaves of bread , One loaf is equal=2 1/4 cups so two becomes 2 ×2 1/4= 9/2

Maria makes the remaing 48 muffins of the flour left so,

One muffin is equal 3 1/4 cups so two becomes 2×3 1/4=13/2

Add both of them

9/2+13/2=11

A body moves s metres in a time t seconds so that s = t3 – 3t2 + 8. Find:
Lady bird [3.3K]

Using derivatives, it is found that:

i) v(t) = 3t^2 - 6t

ii) 9 m/s.

iii) a(t) = 6t - 6

iv) 6 m/s².

v) 1 second.

<h3>What is the role of derivatives in the relation between acceleration, velocity and position?</h3>
  • The velocity is the derivative of the position.
  • The acceleration is the derivative of the velocity.

In this problem, the position is:

s(t) = t^3 - 3t^2 + 8

item i:

Velocity is the <u>derivative of the position</u>, hence:

v(t) = 3t^2 - 6t

Item ii:

v(3) = 3(3)^2 - 6(3) = 27 - 18 = 9

The speed is of 9 m/s.

Item iii:

Derivative of the velocity, hence:

a(t) = 6t - 6

Item iv:

a(2) = 6(2) - 6 = 6

The acceleration is of 6 m/s².

Item v:

t for which a(t) = 0, hence:

6t - 6 = 0

6t = 6

t = \frac{6}{6}

t = 1

Hence 1 second.

How do you solve g= y-c+x for x
SOVA2 [1]
To solve for x just isolate x by moving the other variables so....:
First add c to both sides
g+c= y+x
Subtract y from both sides
g+c-y= x
That should be your final answer (we cannot come up with an actual digit for x because there are no numbers in this equation we simply can make an equation for x)

There is a group of 10 people ordering pizza. If each person
VashaNatasha [74]

Answer:

4

Step-by-step explanation:

If ten people each get three slices, they will need 30 pieces.

10 x 3 = 30

Each pizza has 8 slices, so we divide 30 by 8 to get the number of pizzas needed.

30 / 8 = 3.75

You can't buy 3.75 pizzas, so you must get 4 to ensure everyone gets enough.
