Answer 1

for the first problem:

the equation is x+40=90 (degrees) because since there is a little square, that means that angle is 90 degrees. Since it has been split we can use algebra to solve it. x=50 degrees. They are complementary angles because the add up to 90 degrees.

second one: x= 180-62 degrees or x+62=180 degrees. Since this one is a straight line and all straight lines equal 180 degrees, we can use the same algebra logic and put in 62 degrees. x=118 degrees, and the angles are supplementary because they add up to 180 degrees.

hope this helped!

Answer 2

Answer:

Question 1: x=50°

Question 2: x=118°

Step-by-step explanation:

A right angle has a total of 90 degrees

a straight line has a total of 180 degrees

Question 1:

The first problem is an example of a complementary angle. To work out the value of x you would need to Minus the angle of 40 from the total of 90, this gives you 50. This is because question 1 is a right angle and so is 90°, also by subtracting the angle form the total of 90 you are isolating the value of x.

1) Minus 40 from 90.

[tex]90-40=50[/tex]°

Question 2:

The second question is an example of a supplementary angle. To work out the value of x in the second question you would minus the angle of  62 from the total of 180, this gives you 118. This is because question 2 is a straight line and so has a total angle of 180°, also by subtracting the angle from the total we are isolating the value of x.

1) Minus 62 from 180.

[tex]`180-62=118[/tex]°

Answers

Answer:

117

Step-by-step explanation:

Here, we have to find the result when 4680 is divided by 40.

Meg wants to simplify the process of division here.

We know that 4680 can be written as 4000 + 600 + 80.

So,

[tex]4680 \div 40 = (4000 \div 40) + (600\div 40) + (80\div 40)\\\\\Rightarrow 100 + 15 + 2\\\Rightarrow 117[/tex]

This method makes division very easy if we have to find results of division for large numbers. This example is an illustration of the same.

Please refer to image attached for results.

Hence, Meg gets the result as 117.

Answers

Answer: The radius is 12.

Step-by-step explanation:

75/n where N is representing pie. We have to divide pie to find the diameter.

75/3.14= 24  Now we know the diameter is about 24  so we will divide by 2 to find the radius.

24/2=12

Answer:

1)  12in

Step-by-step explanation:

The circumference is 75, so to find the diameter you have to divide 75 by 3.14. You get 24 approximately. Then divide the diameter by 2, so 24/2=12.

A scale drawing of a square has a side length of 6 millimeters. The drawing has a scale of 1 mm : 7 km. Find the actual perimeter and area of the square.

Answers

A=1764km^2
P=168km

An actual square will ALWAYS have the same lengths on each of the 4 sides. Therefore it will be 6mm all around the square. There are different ways to solve this type of problem but we’ll go with this one.

First you want to understand that the scale is a ratio or a fraction. With fractions you multiply the numerator or denominator, but if you multiply or divide with one, you must with the other. In this case the ratio (we can put it in fraction form) is 1/7. Now you want to make it to where the 1 (because it is a mm) becomes 6 because that’s how many mm we have on each side. To do that you need to find what times 1 is equal to 6 (which is 6 itself).

Now that you found what the numerator will be, we need to also multiply 7 by 6 because what you do with one side you must do to the other. So 7*6 will be 42. Your new fraction (or ratio) is 6/42.

Finally you should know that since a square has 4 sides you need to multiply what one side length of the square is by 4 for the perimeter. Because 6mm is 42km (because of the ratio) then do 42*4 which is 168.

Finding the area is much simpler with the already known lengths, area is l*w, which in this case for the square is just two side lengths times eachother. 42*42= 1764.

The radius of the earth is 3959 miles. A meteor with a diameter of 750 miles strikes the earth in an unpopulated area. What percent of the earths surface is affected by the meteor strike? Is it a 36% be 0.9% C9% or D3.6%

Answers

Answer:

B. 0.9%

Step-by-step explanation:

If the diameter of the meteor is 750 miles, then its radius is 750/2 = 375 miles

The radius of the earth is 3959 miles

Assuming that both bodies are spherical, their surface are:

meteor's surface: π*r² = π*375² = 441786.467 miles²

Earth's surface: π*3959² = 49240321.1 miles²

If 49240321.1 miles² represents 100% then 441786.467 miles² represents:

49240321.1 miles² / 100% = 441786.467 miles² / x%

x = 441786.467/49240321.1*100

A friend bought 2 boxes of pencils and 8 notebooks for school, and it cost him $11. He went back to the store the same day to buy supplies for his younger brother. He spent $11.25 on 3 boxes of pencils and 5 notenooks. How much would 9 notebooks cost?

Answers

Answer:

9 notebooks would cost $6.75

Step-by-step explanation:

How I solved this problem was by taking the data and writing it out first.

During one trip, he got 2 boxes of pencils and 8 notebooks for $11.00

During the second trip, he got 3 boxes of pencils and 5 notebooks for $11.25

This led me to believe that the boxes were definitely more expensive than the notebooks, as there were many notebooks bought during the first trip, yet that trip was cheaper than the second. So, by the process of elimination, I started off the value of the notebooks to be $0.50, and the boxes of pencils to be $3.00, and I continued to experiment with values until I found two values that would work in both scenarios, the values being $2.50 for a box of pencils, and $0.75 for a notebook. (I know there's likely an easier way of doing this, but I haven't done a problem like this in a while, and this method works just fine. It's just a bit more time consuming.)

1st Case: 2(2.50) + 8(0.75) = 11

2 times 2.50 equals 5, and 8 times 0.75 equals 6. 5 added to 6 gives you a sum of 11.

2nd Case: 3(2.50) + 5(0.75) = 11.25

3 times 2.50 equals 7.50, and 5 times 0.75 equals 3.75. 7.50 added to 3.75 gives you a sum of 11.25

Now that it is known how much each notebook costs ($0.75), you would take that value and multiply it by 9, since you're wanting to know how many 9 would cost, and this gives you a product of $6.75.

I hope this helps :)

If you have a cubic polynomial of the form y = ax^3 + bx^2 + cx + d and lets say it passes through the points (2,28), (-1, -5), (4, 220), and (-2, -20) what would the coefficients a, b, c, and d equal? So confused, I'd greatly appreciate help! Thank you!

Answers

Answer:

a = 3

b = 2

c = 0

d = -4

Step-by-step explanation:

Form 4 equations and solve simultaneously

28 = a(2)³ + b(2)² + c(2) + d

28 = 8a + 4b + 2c + d (1)

-5 = -a + b - c + d (2)

220 = 64a + 16b + 4c + d (3)

-20 = -8a + 4b - 2c + d (4)

(1) + (4)

28 = 8a + 4b + 2c + d

-20 = -8a + 4b - 2c + d

8 = 8b + 2d

d = 4 - 4b

Equation (2)

c = -a + b + d + 5

c = -a + b + 4 - 4b+ 5

c = -a - 3b + 9

28 = 8a + 4b + 2c + d (1)

28 = 8a + 4b + 2(-a - 3b + 9) + 4 - 4b

28 = 6a - 6b + 22

6a - 6b = 6

a - b = 1

a = b + 1

220 = 64a + 16b + 4c + d (3)

220 = 64(b + 1) + 16b + 4(-b - 1 - 3b + 9) + 4 - 4b

220 = 60b + 100

60b = 120

b = 2

a = 2 + 1

a = 3

c = -3 - 3(2) + 9

c = 0

d = 4 - 4(2)

d = -4

Step-by-step explanation:

Step 1:  Solve using the first point

(2, 28)

[tex]28 = a(2)^3 + b(2)^2 + c(2) + d[/tex]

[tex]28 = 8a + 4b + 2c + d[/tex]

Step 2:  Solve using the second point

(-1, -5)

[tex]-5 = a(-1)^3 + b(-1)^2 + c(-1) + d[/tex]

[tex]-5 = -a + b - c + d[/tex]

Step 3:  Solve using the third point

(4, 220)

[tex]220 = a(4)^3 + b(4)^2 + c(4) + d[/tex]

[tex]220 = 64a + 16b + 4c + d[/tex]

Step 4:  Solve using the fourth point

(-2, -20)

[tex]-20 = a(-2)^3 + b(-2)^2 + c(-2) + d[/tex]

[tex]-20 = -8a + 4b - 2c + d[/tex]

Step 5:  Combine the first and fourth equations

[tex]28 - 20 = 8a - 8a + 4b + 4b + 2c - 2c + d + d[/tex]

[tex]8 = 8b + 2d[/tex]

[tex]8 - 8b = 8b - 8b + 2d[/tex]

[tex](8 -8b)/2 = 2d/2[/tex]

[tex]4 - 4b = d[/tex]

Step 6:  Solve for c in the second equation

[tex]-5 + 5 = -a + b - c + d + 5[/tex]

[tex]0 + c = -a + b - c + c + d + 5[/tex]

[tex]c = -a + b + d + 5[/tex]

Step 7:  Substitute d with the stuff we got in step 5

[tex]c = -a + b + (4 - 4b) + 5[/tex]

[tex]c = -a + b + 4 - 4b + 5[/tex]

[tex]c = -a - 3b + 9[/tex]

Step 8:  Substitute d and c into the first equation

[tex]28 = 8a + 4b + 2(-a - 3b + 9) + (4 - 4b)[/tex]

[tex]28 = 8a + 4b - 2a - 6b + 18 + 4 - 4b[/tex]

[tex]28 - 22 = 6a - 6b + 22 - 22[/tex]

[tex]6 / 6 = (6a - 6b) / 6[/tex]

[tex]1 + b = a - b + b[/tex]

[tex]1 + b = a[/tex]

Step 9:  Substitute a, b, and c into the third equation

[tex]220 = 64(1 + b) + 16b + 4(-(1 + b) - 3b + 9) + (4 - 4b)[/tex]

[tex]220 = 64 + 64b + 16b + 4(-1 - b - 3b + 9) + 4 - 4b[/tex]

[tex]220 - 100 = 60b + 100 - 100[/tex]

[tex]120 / 60 = 60b / 60[/tex]

[tex]2 = b[/tex]

Step 10:  Find a using b = 2

[tex]a = b + 1[/tex]

[tex]a = (2) + 1[/tex]

[tex]a = 3[/tex]

Step 11:  Find c using a = 3 and b = 2

[tex]c = -a - 3b + 9[/tex]

[tex]c = -(3) - 3(2) + 9[/tex]

[tex]c = -3 - 6 + 9[/tex]

[tex]c = 0[/tex]

Step 12:  Find d using b = 2

[tex]d = 4 - 4b[/tex]

[tex]d = 4 - 4(2)[/tex]

[tex]d = 4 - 8[/tex]

[tex]d = -4[/tex]

Answer:  [tex]a = 3, b = 2, c = 0,d = -4[/tex]
