Each pepperoni slice is 78 of an inch long and costs $0.03. Exactly enough pepperoni slices are laid end to end to have a total length of 56 inches. What is the total cost of these pepperoni slices?

Answer:

24,800m or 24.8km or 24km 800m

Step-by-step explanation:

Perimeter of Rectangle (Given) = 800m or (800/1000)km = 0.8km

Total Distance covered by esi = Perimeter of Rectangle x Number of round ran

= 800m or 0.8km x 31

= 24,800m or 24.8km or 24km 800m

Not sure how you want the answer in so I came up with all possible answers.

Answer:

24.8km

24800m

Step-by-step explanation:

800 x 31 = 24800

24800m

to convert 24800m into km, we divide 24800 by 1000

24800/1000 = 24.8

24.8 km

A population of aardvarks is growing at a rate of 2% per year, there are 714 aardvarks this year and 700 aardvarks were there last year.

An equation is an expression that shows the relationship between two or more variables and numbers.

Let y represent the amount of aardvarks after x years.

It can be represented by the equation:

y = a(1.02)ˣ

If this year there are 714 aardvarks, the amount in the last year is:

714 = a(1.02¹)

a = 700

Answer:

9/20 or forty five percent (45%)

Answer:

(a) y = 25°

(b) x = 90°

(c) z = 25°

Step by step explanation:

Part A

z + 90° + 65° = 180°

z = 180° - 65° - 90°

z = 25°

Part B

x + 90° = 180°

x = 90°

Part C

x + 65° + y = 180°

90° + 65° + y = 180°

y = 25°

A straight line has total 180° angle. A square has 4 sides of each 90° angle. A triangle is build up of 180° interior angle.

The exponential regression equation that fits the data is D. y = 8.04.0.98​ˣ.

The quickest way is probably to do direct substitution. First, let's try f(0). The values of y predicted by the four equations are, respectively, 3.14, 5.32, 10.84, and 8.46.

From here, it looks like C and D are the closest to the observed data. Let's try f(4) on C and D.

10.84(1.77)⁴ = 10.84 × 9.815 = 106.4

8.46(3.51)⁴ =  8.46 × 151.4 = 1284

Therefore, the exponential regression equation that fits the data is y = 8.04.0.98​ˣ.

A major arc is an arc that is greater than 180 degrees.

A minor arc is an arc less than 180 degrees.

An acute angle is an angle less than 90 degrees.

A central angle is an angle created in the center of a circle with 2 sides being the radius.

Thus, we can see in the figure that we are talking about the angle so we can eliminate the major arc and minor arc.

Now, we clearly see that the angle is greater than 90 degrees so it cannot be an acute angle.

The correct answer is the central angle as it goes with the definition.

Answer:

9

Step-by-step explanation:

He had 36 Marbles and he gives all to his four friends. And all friends get the same number of marbles so we will have to do division which will be :

36{marbles} divide by 4{friends}=9 so each friend got 9 marbles.

Each friend will have 9 marbles

Division is a method of distributing a group of things into equal parts. It is one of the four basic operations of arithmetic, which gives a fair result of sharing.

The division is an operation inverse of multiplication. If 3 groups of 4 make 12 in multiplication; 12 divided into 3 equal groups give 4 in each group in division.

Given that:

Answer:

f(-5) = -6  

f(-2.6) = 2.4

f(2.1) = 9.41

Step-by-step explanation:

In the question, we are told to find f(-5), f(-2.6), and f(2.1). The numbers in the parentheses represent x.

First, let's look at f(-5). Which equation should we use because x is -5? We should use the first equation because -5 is less than -3. Plug into the equation and solve:

f(-5) = -6      (We didn't have to do much because anything less than -3 equals -6)

Now, let's look at f(-2.6). We should use the equation in the middle because -2.6 is between -3 and 0. Plug -2.6 in the equation and solve:

f(-2.6) = -2.6 + 5

f(-2.6) = 2.4

Lastly, let's look at f(2.1). We should use the third equation because x is greater than 0. Plug 2.1 in the equation and solve:

f(2.1) = [tex](2.1)^{2} +5[/tex]

f(2.1) = 4.41 + 5

f(2.1) = 9.41

Therefore, the final answers are:

f(-5) = -6  

f(-2.6) = 2.4

f(2.1) = 9.41

Answer:

  -2.71

Step-by-step explanation:

This exponential equation can be solved by rewriting it so there is only one base, then using logarithms.

__

  2^x = 3^(x+1) . . . . . given

  2^x = 3·3^x . . . . . . eliminate the constant in the exponent

  (2/3)^x = 3 . . . . . . . divide by 3^x

  x·log(2/3) = log(3) . . . . take logarithms

  x = log(3)/log(2/3) ≈ -2.7095113

The value of x is about -2.71.

__

Alternate solution

Taking logarithms transforms this exponential equation to a linear equation.

  x·log(2) = (x +1)·log(3) . . . . take logs

  x(log(2) -log(3)) = log(3) . . . . . . subtract x·log(3)

  x = log(3)/(log(2) -log(3)) = log(3)/log(2/3) . . . . . same result as above

Answer:

x = 129°

Step-by-step explanation:

∠ ABD and ∠ DBC are a linear pair and sum to 180° , then

y + ∠ DBC = 180°

107° + ∠ DBC = 180° ( subtract 107° from both sides )

∠ DBC = 73°

the exterior angle of a triangle is equal to the sum of the 2 opposite interior angles , then

x = ∠ DBC + z = 73° + 56° = 129°

Work Shown:

(160 with blue eyes)/(500 total) = (x with blue eyes)/(2500 total)

160/500 = x/2500

x = 2500*(160/500)

x = 800

------------

Another approach:

160/500 = 0.32 = 32% of the first group has blue eyes

Assuming this percentage is the same for any group, then,

32% of 2500 = 0.32*2500 = 800 people of the second group are estimated to have blue eyes, of the 2500 total.
