For a Circle of radius is 5 feet, find the arc length s subtended by a central angle of 42 degrees

Answers

[tex]\bf \textit{arc's length}\\\\ s=\cfrac{r\theta \pi }{180}\qquad \begin{cases} r=radius\\ \theta =angle~in\\ \qquad degrees\\ ------\\ r=5\\ \theta = 42 \end{cases}\implies s=\cfrac{5\cdot 42\cdot \pi }{180}[/tex]

The arc length subtended by a central angle of 42 degrees in a circle of radius 5 feet is  3.665 feet.

What is Circle?

A circle is a shape consisting of all points in a plane that are at a given distance from a given point, the centre.

The formula for arc length is given by:

s = rθ

where s is the arc length, r is the radius of the circle, and θ is the central angle subtended by the arc in radians.

To use this formula, we first need to convert the central angle from degrees to radians:

θ = (π/180) × 42 = 0.733 radians

Now we can plug in the values of r and θ into the formula to get:

s = 5 × 0.733

= 3.665 feet

Therefore, the arc length subtended by a central angle of 42 degrees in a circle of radius 5 feet is 3.665 feet.

b - 11 + b = 87
2b - 11 = 87
2b = 87 + 11

A certain recipe calls for 2/3 cup of flour. A chef is making an amount that is 3/7 of the recipe . How much should flour should the chef use?

Answers

2/7 cup of flour



Simply multiply 2/3 by 3/7 to get the answer. To multiply 2 fractions together, you multiply the numerators together and then multiply the denominator together.



2/3 x 3/7 = 6/21



But 6/21 can be expressed in a simpler fashion. Notice that both 6 and 21 can be evenly divided by 3. So divide both the numerator and denominator by 3

(6/3)/(21/3) = (2)/(7) = 2/7

The price of gourmet coffee beans at the corner market has increased 10% per year over the past several years if the current cost is $40 per pound what did a pound of gourmet beans cost two years ago

Answers

$20 because 10% of 40 is 10 and the price now is 40 so 2 years before would have been 20

Answer: $32.4

Step-by-step explanation:

Given : The price of gourmet coffee beans at the corner market has increased 10% (0.1) per year over the past several years.

The current cost is $40 per pound .

The exponential decay equation is given by :-

[tex]y=A(1-r)^x[/tex], where r is the rate of decay and A is the initial amount and x is the time period.

Put A = 40 , r= 0.1 and t=2, we get

[tex]y=40(1-0.1)^2=\$32.4[/tex]

Hence, the cost of  a pound of gourmet beans two years ago= $32.4

A. Associative Property
B. Commutative Property
C. Opposite of a Sum Property

Answers

The answer is Commutative Property.

Answer:

Option B is correct.

Commutative property is used here.

Explanation:

Commutative Property states that we can add any number in any order, we will get the same result i.e, a+b = b+a.

let a = -4.8 and b = (3.2+(-1.6))

then, using commutative property we have;  

a+b=b+a then,

−4.8 + (3.2 + (−1.6)) = (3.2 + (−1.6)) + (−4.8).



Solve for x. 4−(2x+4)=5
A x=6
B x=−10
C x=−52

Answers

4 - (2x + 4) = 5
4 - 2x - 4 = 5
-2x = 5
x = - 5/2 <==

The solution for x in the equation 4 - (2x + 4) = 5 is x = -5/2. So, the correct choice is x = -5/2. Option c is the correct choice.

To solve for x in the equation 4 - (2x + 4) = 5, follow these steps:

1. First, simplify the equation by combining like terms. Start by removing the parentheses by distributing the negative sign:

  4 - 2x - 4 = 5

2. Now, simplify further by combining the constants on the left side of the equation:

  (4 - 4) - 2x = 5

  0 - 2x = 5

3. Next, isolate the variable x by getting rid of the -2 coefficient. To do this, divide both sides of the equation by -2:

  (0 - 2x) / -2 = 5 / -2

  0 / -2 - (2x / -2) = -5/2

  0 + x = -5/2

4. Finally, simplify:

  x = -5/2

So, the solution for x is:

x = -5/2

So,  Option c is the correct choice.

A one-minute advertisement on a local television station during prime time (8-10p.m.) costs the advertiser $12,800. To the nearest cent, how much does the advertisement cost per second? Show your work using dimensional analysis.

Answers

To determine the cost per second can be calculated by converting the given unit in terms of second. The conversion factor that will be used is 1 minute is equal to 60 seconds. Also, use proper dimensional analysis as shown below.

      R = ($12,800 / minute) (1 minute / 60 seconds)

Jeff prepares meals in the home of his customers. His fixed cost for transportation and supplies is $14.50. The labor and groceries needed for each family meal is $8.80, so the expense function is E=5.7q+8.8. T or F

Answers

The expense function is:E ( q ) = m q + b,where b stays for Fixed costs.In this case:m = 8.8 ( the labor and groceries for each family meal ) and b = 14.5So E = 8.8 q + 14.5,  not E = 5.7 q + 8.8Answer: False

Answer:

The given equation is false

Step-by-step explanation:

Given equation : E= 5.7q+8.8

To show : It is true or false

Solution : Cost of transportation and supplies is fixed = $14.50

Cost of labor and groceries for each family meal =$8.80

Let x is the number of meals

so, according to the question Expense function for x number of meals is

Expense function = x(cost of labor and groceries for 1 family meal)+ cost of  transportation and supplies(fixed)

E= 8.80x+14.50  which is the required equation.

Therefore, given equation is false.

Two trains leave the same station at the same time, but are headed in opposite directions. One train travels at 50 miles per hour and the other train travels at 60 miles per hour. How much time passes until the trains are 660 miles apart?

Answers

Let n =  the hours elapsed when the two trains are 660 miles apart.

Let the first train travel east and the second train travel west.
The distance traveled by the first train is
x = (50 mi/h)*(n h) = 50n mi

The distance traveled by the second train is
y = (60 mi/h)*(n h) = 60n h

The distance between the two trains after n hours is
x + y = 50 n + 60n = 110n mi

Because this distance is 660 miles, therefore
110n = 660
n = 6 hours

Answer: 6 hours
