The answers are 4. a) 15.7 cm, b) 26.25 m, 5. a) 128.74 cm, b) 40.82 mm, c) 45 cm and 6. 777.28 cm
Given are the circles and the circular items we need to find their circumference,
Circumference of a circle = 2π × radius = Diameter × π
4. a) Circumference = 5 × 3.14 = 15.7 cm
b) Circumference = 8.36 × 3.14 = 26.25 m
5. a) Circumference = 41 × 3.14 = 128.74 cm
b) Circumference = 13 × 3.14 = 40.82 mm
c) Circumference = 14.3 × 3.14 = 45 cm
6.
The perimeter of the cloth = circumference of the circular ends plus length in the middle,
= 76 × 2 × 3.14 + 150 × 2
= 477.28 + 300
= 777.28 cm

Find P(x)=−2x2+x6−4x+1 when x=−2.
Hey there!
p(x) = 2x^2 + x^4 - 4x + 1
y = 2x^2 + x^4 - 4x + 1
y = 2(-2)^2 - 2^4 - 4(-2) + 1
y = -4^2 - 16 - 4(-2) + 1
y = 8 - 16 - (-8) + 1
y = - 8 - (-8) + 1
y = 0 + 1
y = 1
Therefore, your answer is: y = 1

Natalie uses 9.1 pints of white paint and blue paint to paint her bedroom walls.3/5 of this amount is white paint,the rest is blue paint .how many pints of blue paint did she use to paint her bedroom walls
Let:
T = Total amount of paint
x = Amount of blue paint
y = Amount of white paint
So:
\(x+y=T\)3/5 of this amount is white paint, so:
\(\begin{gathered} y=\frac{3}{5}\cdot T \\ y=\frac{3}{5}(9.1) \\ y=5.46 \\ \end{gathered}\)Therefore, solving for x:
\(\begin{gathered} x+5.46=9.1 \\ x=9.1-5.46 \\ x=\frac{91}{25}=3.64 \end{gathered}\)The gross domestic product (GDP) of the United States is defined as

what is the total number of miles if he bikes 21 hours?
answer as a decimal
Replace h in the equation with 21 hours and solve for d:
D = 8/6(21) + 4 1/2
D = 28 + 4 1/2
D = 32 1/2

How to obtain probabilities using the normal distribution?The z-score of a measure X of a variable that has mean symbolized by \(\mu\) and standard deviation symbolized by \(\sigma\) is obtained by the rule presented as follows:
\(Z = \frac{X - \mu}{\sigma}\)
The z-score represents how many standard deviations the measure X is above or below the mean of the distribution, depending if the obtained z-score is positive or negative.Using the z-score table, the p-value associated with the calculated z-score is found, and it represents the percentile of the measure X in the distribution.The parameters for this problem are given as follows:
\(\mu = 10, \sigma = 2.7\)
The proportion over 15.5 pounds is one subtracted by the p-value of Z when X = 15.5, hence:
Z = (15.5 - 10)/2.7
Z = 2.04
Z = 2.04 has a p-value of 0.9793.
1 - 0.9793 = 0.0207.
The proportion under 11.9 pounds is the p-value of Z when X = 11.9, hence:
Z = (11.9 - 10)/2.7
Z = 0.7
Z = 0.7 has a p-value of 0.7580.
The proportion between is the subtraction of the p-values, hence:
0.9793 - 0.7580 = 0.2213 = 22.13%.

What number is the penguin covering? 2023 2003 = 203 × 2023 + * × 2023
Answer:
The missing number should be 20.
We can rewrite the equation as:
2023 × 2003 = 203 × 2023 + 20 × 2023
Simplifying the right-hand side:
2023 × 2003 = 203 × 2023 + 40460

A circle with a diameter of 10 inches has a circumference of a square, what is the length of each side of the square?
The circumference is πd, and the diameter is 10, so the circumference is 10π. All sides of a square are equal, so the length of each side is 10π/4, which is 2.5π.
The length of each side of the square is 2.5π

alls arrive at a call center at an average rate of 100/min. Depending on the availability of a service representative, calls may be either answered immediately or wait in line for the next available representative. On average, including waiting time, a call requires 4.4 minutes. How many callers, on average are in the system at any given time
Answer:
the number of callers on average are in the system at any given time is 440
Step-by-step explanation:
Given that
The calls that arrive in a call center have an average rate of 100 per min
But it we involve the waiting time so the call needed 4.4 minutes
We need to to find no of callers are in the system at any given time
SO,
= 100 per min × 4.4
= 440
hence, the number of callers on average are in the system at any given time is 440

In order to find the figure reflected over the x-axis, we need to change the signal of the y-coordinate of all points.
The points of the original figure are:
(-6, -6)
(-6, -4)
(-4, -3)
(-4, -6) (big dot)
After the reflection over the x-axis, the y-coordinates are changed, so we have:
(-6, 6)
(-6, 4)
(-4, 3)

A pizzeria stores flour in a 5-gallon container. Each pizza they make uses 7 cups of flour. Can the cooks at the pizzeria make a dozen pizzas without refilling the canister? Complete the explanation.
The canister holds 80 cups and they need 84 cups of flour to make a dozen pizzas. So, the cooks cannot make a dozen pizzas without refilling the canister. The solution has been obtained by using unitary method.
What is the unitary method?
The unitary technique is used to first calculate the value of each individual unit, and only then is the value of the necessary quantity of units calculated.
We are given that a pizzeria stores flour in a 5-gallon container. We assumed that 16 cups make 1 gallon.
So, number of cups that will make 5 gallon is 16 * 5 = 80 cups
Since, each pizza they make uses 7 cups of flour. So, for making 12 pizzas, they require 12 * 7 = 84 cups of flour.
Hence, the cooks cannot make a dozen pizzas without refilling the canister.

Derivative of sin(x+y)
Answer:
\( \frac{dy}{dx} = \frac{ \cos(x + y)}{[1 - \cos(x + y)] } \)
Step-by-step explanation:
Let y = sin(x+y)
Differentiating with respect to x on both sides.
\( \frac{dy}{dx} = \frac{d}{dx} \sin(x + y) \\ \\ \frac{dy}{dx} = \cos(x + y)\frac{d}{dx} (x + y) \\ \\ \frac{dy}{dx} = \cos(x + y)(1 + \frac{dy}{dx}) \\ \\ \frac{dy}{dx} = \cos(x + y) +\cos(x + y) \frac{dy}{dx} \\ \\ \frac{dy}{dx} - \cos(x + y) \frac{dy}{dx} = \cos(x + y) \\ \\ \frac{dy}{dx} [1 - \cos(x + y)] = \cos(x + y) \\ \\ \purple {\bold {\frac{dy}{dx} = \frac{ \cos(x + y)}{[1 - \cos(x + y)] }}} \)
