In the PEMDAS method of solving , it goes to the five basic operations

1.Parenthesis 2. Exponents 3. Multiplication 4. Addition 5.Substraction

In this exercise there are NOT parenthesis, so then the first operation is Exponentiation and 2nd operation is Multiplication

So the answer is Multiply, the first option.

From the right triangle, and using the definitions of the tangent and the cosine functions, we have:

From the problem, we identify:

Finally, using these values, we can find b and c.

Using (1):

Using (2):

We need to find which expression represents the situation given, in this case we have two values a distance (80 ft) and the elapsed time (40 s). The time is the input of the equation, it will be placed on the "x" variable and the distance is the output of the equation, it will be placed on the "y" variable. We need to find the expression that outputs "80" when we input 40. Let's check them one by one:

A.

This outputs 20 ft when we input 40 s, therefore it is not this one.

B.

This one outputs 160 ft when we input 40 s, therefore it is not this one.

C.

This one outputs 80 ft when we input 40 s, therefore this is the correct expression.

We now need to use this expression to calculate the distance the person will travel in 10 seconds, so we will make x equal to 10 s.

The person will walk 20 ft.

The correct option is "C".

Answer:

The correct number is -27.

Step-by-step explanation:

-81 ÷ 3 = -27

The simplified form of the expression 29 - ( 11 - 2³ ) + 6² ÷ 4 is 35

Given the expression in the question;

29 - ( 11 - 2³ ) + 6² ÷ 4

To simply, replace 2 raised to the power of 3 with 8 and 6 raised to the power of 2 by 36

29 - ( 11 - 2³ ) + 6² ÷ 4

29 - ( 11 - 8 ) + 36 ÷ 4

Now, remove the parenthesis by performing the operation inside the parenthesis.

29 - ( 11 - 8 ) + 36 ÷ 4

29 - 3 + 36 ÷ 4

Now, divide 36 by 4

29 - 3 + 36 ÷ 4

29 - 3 + 9

Next, add -3 and 9

29 + 6

Add 29 and 6

35

Therefore, 35 is the simplified form of the expression.

The number line 5 ≤ 8-3x  shows the solution to the inequality as x cannot be more than 1.

A inequality compares two values and indicates whether one is smaller, larger, or simply not equal to the other.

a  ≠ b is the information that a and b are not equal.

If a  > b, a is greater than b. (these two are defined as strict inequality)

a ≤ b proves that a is less than or equal to b

a ≥ b proves that a is greater than or equal to b

The number line 5 ≤ 8-3x  shows the solution to the inequality as x cannot be more than 1.

If x is more than 1, lets say 2

Then the inequality as follows

5 ≤ 8-3(2) ≤ 14

Long division gives the answer of 24 when 72 is divided by 3.

Long division in mathematics is a strategy for breaking down complicated division problems into a series of simpler steps. It is the approach that division-based issues are typically solved using. The dividend, the quotient, the remainder, and the divisor can all be seen in the following long division.

So as we know:

Start by arranging it so that the dividend 72 is on the right side and the divisor 3 is on the left:

 3 ⟌ 7 2  

Start by arranging it so that the dividend 72 is on the right side and the divisor 3 is on the left:

    2    

   3 ⟌ 7 2  

Write the result (3 x 2 = 6) underneath the dividend after multiplying the divisor by the outcome from the previous step.

     2    

   3 ⟌ 7 2  

       6    

Write the solution below after subtracting the result from the previous step from the dividend's first digit (7 - 6 = 1).

Reduce the dividend's second digit (2) as follows:

    2    

   3 ⟌ 7 2  

     - 6    

       1 2  

The bottom number (12) is multiplied by the divisor (3) four times (s). Put 4 thus on top

Subtract the result of the previous step (3 x 4) from the divisor to get the solution (12), which you should write at the bottom:

  2 4  

   3 ⟌ 7 2  

     - 6    

       1 2  

      1 2  

Take the number above it and deduct the outcome from the preceding calculation. Write the response at the bottom after calculating (12 - 12 = 0).

The top number is the solution, and the remaining value is the bottom one.

Therefore, the result of 72 divided by 3 using long division is 24.

We get 700,000 after rounding off to the place value of the underlined digit in the number 698,072.

According to the question,

We have the following number with 6 as the underlined digit:

698,072

When rounding off the number, please note that the digits to the right of the underlined digit would be zero. However, we need to be careful where we need to scale up the underlined number or it would remain the same.

For this, we need to check the number to the right of the underlined digit. If the number right next to the underlined digit is greater than 5 then the underlined digit has to be scaled up. And if it is less than 5 then the underlined digit remains the same.

So, after rounding off we will get:

The highest common factor of the given number is 35.

The biggest positive number that divides each integer in a set of two or more is known as the greatest common divisor in mathematics. The GCD of two integers x, and y is the greatest common divisor of x and y. A group of numbers' largest factor that they all share is known as the group's greatest common factor (GCF). Components 2 and 4 are shared by the numbers 12, 20, and 24, for instance. We claim the GCF of 12, 20, and 24 equals 4 since 4 is the largest. The greatest integer that may divide two or more numbers is known as the highest common factor (HCF), sometimes known as the GCF. The definition of highest is the highest or largest number.

Explanation:

Imagine a rectangle that is 12 by 26. Multiplying the length and width will get us the area.

We can break the 12 into 10+2

Also, break the 26 into 20+6

Check out the diagram below. We have 4 smaller rectangles. Finding the product of those sub-areas will then get us the partial products needed.

In the bottom right corner we have a 2 by 6 rectangle, so it has area 2*6 = 12 square units. This is one of the four partial products. The other partial products are found the same way.

Once you determine the four partial products, we then add them up

12+60+40+200 = 12+100+200 = 12+300 = 312

Therefore, 12*26 = 312 which we can use a calculator to confirm.

The measure of angle B in triangle ABC is 158°.

A triangle is a 2-dimensional closed shape with three sides, three angles, and three vertices. A triangle would be a category of polygon.

For the given angles of the triangle ABC.

∠BAC = 78° , ∠CAD = 46° and ∠ADB = 110°.

Now,

∠BAC = ∠BAD + ∠DAC

Put the values;

78° = ∠BAD + 46°

∠BAD = 78° - 46°

∠BAD = 32°

Now, in a triangle; the sum of all three angles is 180°.

In triangle ADB

∠ABD + ∠BAD + ∠BDA = 180°

Put the values;

∠ABD +  32° +  110°  =  180°

∠ABD = 180°  -  142°

∠ABD = 158°
