Answer:

The measure of the arc is 160 degrees

Step-by-step explanation:

The picture of the question in the attached figure

we know that

The measure of the external angle is the semi-difference of the arches it covers.

so

[tex]20^o=\frac{1}{2}[(360-x)^o-x^o][/tex]

solve for x

[tex]40^o=360^o-2x[/tex]

[tex]2x=360^o-40^o\\2x=320^o\\x=160^o[/tex]

The arc measure that the satellite can see is 20°.

An arc measure is the central angle that corresponds to a given arc on a circle. In this case, the satellite views the earth at an angle of 20°. The arc measure that the satellite can see is also 20°.

Step-by-step explanation:

because 3+6=9 so he is 9 miles from his starting point

Answer: 30 min.

Step-by-step explanation: for this, you have to find the gcf of 5 and 6, which is 30.

Final answer:

Mike and Sam will both cross the starting line together after 30 minutes of running, as 30 minutes is the least common multiple of their individual lap times of 5 and 6 minutes.

Explanation:

To find out how long it will take for Mike and Sam to cross the starting line together again, we need to determine the least common multiple (LCM) of their lap times. Mike runs a lap in 5 minutes and Sam runs a lap in 6 minutes. The LCM of 5 and 6 will give us the first time they both cross the starting line at the same time after they start running.

To calculate the LCM of 5 and 6, we list the multiples of each number until we find a common one:

5, 10, 15, 20, 25, 30, ...

6, 12, 18, 24, 30, ...

The smallest common multiple of 5 and 6 is 30. Therefore, Mike and Sam will both cross the starting line together after 30 minutes of running.

the surface area of the equilateral triangular pyramid is approximately 21.03 square inches.

Let's calculate the surface area of the pyramid.

The lateral area of the pyramid, which is the sum of the areas of the three triangular faces, can be calculated using the formula:

[tex]\[ LA = \frac{1}{2} \times \text{perimeter of the base} \times \text{slant height} \][/tex]

We've already determined the perimeter of the base is 4.8 inches and the slant height is 8.3  inches. Substituting these values:

[tex]\[ LA = \frac{1}{2} \times 4.8 \times 8.3 = 19.92 \text{ square inches} \][/tex]

However, this only gives us the lateral area. To find the total surface area, we need to add the area of the base. Since it's an equilateral triangle, we can use the area formula for equilateral triangles:

[tex]\[ A_{\text{base}} = \frac{\sqrt{3}}{4} \times (\text{side length})^2 \][/tex]

The side length is [tex]\( \frac{4.8}{3} = 1.6 \)[/tex] inches, so:

[tex]\[ A_{\text{base}} = \frac{\sqrt{3}}{4} \times (1.6)^2 = \frac{\sqrt{3}}{4} \times 2.56 \approx 1.1084 \text{ square inches} \][/tex]

The total surface area is then the sum of the lateral area and the area of the base:

[tex]\[ SA = LA + A_{\text{base}} = 19.92 + 1.1084 = 21.0284 \text{ square inches} \][/tex]

Thus, the surface area of the equilateral triangular pyramid is approximately 21.03 square inches.

The question probable maybe:

An equilateral triangular pyramid has a slant height of 8.3 inches. The triangular base has a perimeter of 4.8 inches and an area of 1.1084 square inches. Find the surface area of the pyramid.

Answer:

Here the degree of the polynomial is 11.

Step-by-step explanation:

To find the degree of the multivariate polynomials, we need to add up the powers of all the variables.   So the total degree is given by the sum of all the powers of the highest powers terms.

Now in the given polynomial [tex]-3w+x^6y^5-2+5y^4w^3x^2[/tex]

the term with the highest total powers is [tex]x^6y^5[/tex] and thus the total power is 6+5=11.

And hence the degree of this polynomial is 11.

The cost of one hot dog is $1.75

The cost of one hamburger is $1.5

Step-by-step explanation:

Let,

The equations can be formed as :

7x + 4y = 18.25  --------(1)

4x + 7y = 17.50  --------(2)

Multiply eq (1) by 4 and eq (2) by 7,

   28x + 16y = 73

- (28x + 49y = 122.5)

         - 33y = - 49.5

y = 49.5/33

y = 1.5

The cost of one hamburger is $1.5

Substitute y=1.5 in eq (1),

7x + 4(1.5) = 18.25

7x = 18.25 - 6

x = 12.25/7

x = 1.75

The cost of one hot dog is $1.75

Step-by-step explanation:

its 20 and a half because 16+20=36 and you just need to add a half to 20 since your taking it away

Answer:

c=20.5 or 41/2

Step-by-step explanation:

c- 1/2 + 16=36

Make C the subject

c=36-16+1/2

c=20+1/2

Using LCM

c=(40+1)/2

c=41/2

c=20.5

To check if we are correct, we substitute c with 41/2. and then both sides of the equation must be equal

c- 1/2 + 16=36

41/2-1/2+16=36

To graph

[tex]y \: < \: \frac{1}{4} x[/tex]

You first graph the boundary line

[tex]y = \frac{1}{4} x[/tex]

This is a dashed line going through the origin with slope 1/4.

We test the point (0,1) to get: 1<0 which is false. So we shade the lower half-plane.

To graph

[tex]y \: < \: - 6x + 6[/tex]

We first graph line

[tex]y = - 6x + 6[/tex]

By plotting (0,6), and (1,0)

We draw a dashed boundary line.

We test the origin:

0<6 which is true so we shade the left half-plane .

The intersection of both shaded regions represent the solution set.

Answer:

x = -4/3

Step-by-step explanation:

Step 1:  Distribute

3(5x + 8) = 4(6x + 9)

15x + 24 = 24x + 36

Step 2:  Subtract 15x from both sides

15x + 24 - 15x = 24x + 36 - 15x

24 = 9x + 36

Step 3:  Subtract 36 from both sides

24 - 36 = 9x + 36 - 36

-12 = 9x

Step 4:  Divide both sides by 9

-12 / 9 = 9x / 9

-4/3 = x

Answer:

The generalization will be biased because people living in cities that are not as big as New York, Los Angeles and rural areas of the country were excluded from the possibility of being included in the sample.

Step-by-step explanation:

The sample is therefore not a true representation of the population.

Final answer:

The generalization would be biased because it only includes opinions from large cities, which aren't representative of the entire population, leading to sampling bias. This results in a biased sample as it overlooks the diversity in lifestyles and circumstances found in different geographic areas.

Explanation:

If a company conducts a survey among people who only live in large cities like New York and Los Angeles, and then makes a generalization from this survey, the generalization will be biased. This is because the perspectives of people living in large cities are not necessarily representative of the entire population, which includes people from smaller towns, rural areas, and different socioeconomic backgrounds. Such a sampling method leads to a sampling bias, since it does not adequately reflect the diversity of the whole population.

For instance, urban populations may have different lifestyles, access to services, and daily challenges compared to those living in suburban or rural areas. Therefore, if a survey's findings from a city population are applied to the general population, it may result in an inaccurate picture of the opinions, behaviors, or characteristics of the entire population. This exemplifies a biased sample, as the sampling method does not capture the full range of variables affecting the population as a whole.

Answer:

A system of equations that allows you to solve for how many bags of each candy Oscar bought is [tex]16x+8(x+5)=400[/tex] and The number of bags of lemon drops and number of bags of beans are 15 and 20 respectively

Step-by-step explanation:

Let x be the number of bags of lemon drops

We are given that The number of bags of beans was 5 more than the number of bags of lemon drops

So, The number of bags of beans =x+5

Jelly bean bags weigh 8 ounces, and drop bags weigh 16 ounces each.

So, Weight of x bags of lemon drops = 16x

So, Weight of (x+5) bags of lemon drops = 8(x+5)

The total weight of all the bags of candy was 400 ounces.

So, [tex]16x+8(x+5)=400[/tex]

[tex]16x+8x+40=400[/tex]

[tex]24x+40=400[/tex]

[tex]24x=360[/tex]

[tex]x=\frac{360}{24}[/tex]

x= 15

The number of bags of lemon drops are 15

The number of bags of beans =x+5 =15+5=20

Hence a system of equations that allows you to solve for how many bags of each candy Oscar bought is [tex]16x+8(x+5)=400[/tex] and The number of bags of lemon drops and number of bags of beans are 15 and 20 respectively
