A lid on a circular container has a diameter of 9 cm. What is the approximate area of the lid? Use 3.14 to approximate pi and round your answer to the nearest hundredth._______ cm2

Answers

area=pir^2

diameter/2=radius
diameter=9
d/2=9/2=4.5=r

area=pi4.5^2
area=pi20.25
aproxpi=3.14
area=63.585
round hundreth
area=63.59

answer is 63.59cm^2

Hi there, A=1/4πd²=1/4*π*9²=63.61725cm², that would round to 63.62cm². Therefore, the answer would be 63.62 cm²

What is 50% of 20 in a fraction?

Answers

50% of 20 is 10, because it's half of 20.
So the fraction of a whole number is over 1,
it's 10/1

$50\%\cdot20=0.5\cdot20=10=(10)/(1)$

How do I solve forax+by=c

Answers

Answer:

Subtract ax from both sides. ax + by − ax = c − ax.

Simplify. by = c − ax.

Divide both sides by b ; b ≠ 0. by b = c b − ax b ; b ≠ 0.

Simplify. y = c − ax b ; b ≠ 0.

How can I adjust a quotient to solve a division problem

Answers

for example you have five times twevle people so that's 60people. 5 times 12 is 60 and 12 times 5 is 60 so 60 dividedby 5 is 12 and 60 divided 12 is five. that's what division can be like

Final answer:

To adjust a quotient in a division problem, you can multiply both the dividend and divisor by the same number.

Explanation:

To adjust a quotient in order to solve a division problem, you can multiply both the dividend and divisor by the same number. This will not change the value of the quotient, but it will make the division easier to solve.

For example, if you have 12 ÷ 3 and you want to adjust the quotient, you can multiply both 12 and 3 by 10 to get 120 ÷ 30. The quotient remains the same, but now you can easily divide 120 by 30 to get the answer, which is 4.

In summary, adjusting a quotient involves multiplying both the dividend and divisor by the same number to simplify the division problem.

If s(x) =2-x^2and t(x) =3x which value is equivalent to (s·t)(-7)

Answers

the answer is 24 (x) -78

Answer:

987

Step-by-step explanation:

(s.t)(x) = s(x) × t(x) = 3x(2 - x²) = 6x - 3x³

To evaluate (s.t)(- 7) substitute x = - 7 into the product

(s.t)(- 7) = 6(- 7) - 3(- 7)³ = - 42 + 1029 = 987
