Angle Theorems for triangles

Answers

Answer 1

Answer:

Step-by-step explanation:

The interior angles of a triangle add to 180°:a + b + c = 180°

Angles c and d make a straight angle, which is 180°:d + c = 180°

So d + c equals a + b + c:d + c = a + b + c.

Subtract c from both sides:d = a + b.

If an airplane travels at an average speed of 510 mph, how far does the airplane move in 50 minutes?

Answers

Answer:

425 miles

Step-by-step explanation:

Divide 510 by 60 to get miles per minute and then multiply by 50 to get miles in 50 minutes

The airplane move 425 miles in 50 minutes.

what is Speed- Distance Formula?Speed = Distance/TimDistance = Speed X Time, and Time = Distance / Speed

Given:

Speed= 510 mph

Time= 50  min = 50/60 hour.

So, speed= Distance / Time

510 = Distance / (5/6)

510 x 5/6 = Distance

Distance = 425 miles

Hence, the Airplane travel 425 miles.

Answer:

The multiplicative inverse is 2

Step-by-step explanation:

In mathematics, we call the number 1 the multiplicative identity because if we multiple any number by 1, we get that same number as our answer. A multiplicative inverse of a number, x, is a number y, such that if we multiply x times y, then we get the multiplicative identity. That is, x × y = 1.

In a survey of 2,800 people who owned a certain type of car, 840 said they would buy that type of car again. What percent of the people surveyed were satisfied with the car?​

Answers

Answer:

30% of people surveyed were satisfied with the car.

Step-by-step explanation:

We are given:

Total participants in survey= 2800

People satisfied with car = 840

We need to find percent of the people surveyed were satisfied with the car.

The formula used is: [tex]\frac{People \ satisfied \ with \ car}{Total \ participants \ in \ survey} \times 100[/tex]

[tex]=\frac{840}{2800}\times 100\\=30\%[/tex]

So, 30% of people surveyed were satisfied with the car.

Mrs. MaryAnn is giving treat sacks out for Valentines Day. She has 30 pencils and 42 smiley face stickers. Mrs. Maryann wants each treat sack to be identical with no leftovers Whats the greatest number of treat sacks she can make? How many pencils will be in each treat sack? How many smiley face stickers will be in each treat sack?

Answers

Answer:

6 number treat sacks and

each sack having 5 pencils and 7 smiley face stickers.

Step-by-step explanation:

Given that:

Number of pencils = 30

Number of smiley face stickers = 42

Mrs. MaryAnn wants to divide everything in identical treat sacks so that there are no leftovers.

To find:

The number of greatest number of treat sacks.

Solution:

First of all, we need to find the Highest Common Factor of the two numbers.

Factorization method:

[tex]30 = \underline2\times \underline3\times 5[/tex]

[tex]42 = \underline2\times \underline3 \times 7[/tex]

Here, the common numbers 2 and 3.

So, highest common factor is [tex]2\times 3 = 6[/tex]

If we divide 30 by 6, we get 5 and

If we divide 42 by 6, we get 7

So, if we take 5 pencils and 7 smiley face stickers in one treat sack and if we make 6 such treat sacks then there will be equal division and no leftovers.

Therefore, the answer is:

6 number treat sacks and

each sack having 5 pencils and 7 smiley face stickers.

solve for x -5(-x+1)-3x-1=-12

Answers

Answer:

x = -2

General Formulas and Concepts:

Order of Operations: BPEMDAS

Step-by-step explanation:

Step 1: Define equation

x - 5(-x + 1) - 3x - 1 = -12

Step 2: Solve for x

Distribute -5:                                   x + 5x - 5 - 3x - 1 = -12Combine like terms:                       3x - 6 = -12Add 6 to both sides:                       3x = -6Divide 3 on both sides:                  x = -2

Step 3: Check

Plug in x to verify it's a solution.

Substitute:                         -2 - 5(-(-2) + 1) - 3(-2) - 1 = -12Multiply:                             -2 - 5(2 + 1) + 6 - 1 = -12Add:                                   -2 - 5(3) + 6 - 1 = -12Multiply:                             -2 - 15 + 6 - 1 = -12Subtract:                            -17 + 6 - 1 = -12Add:                                   -11 - 1 = -12Subtract:                            -12 = -12

Answers

Answer:

B. (x - 3²)(y-6)

Step-by-step explanation:

 Find the expression with a value of 30;

  when x  = -1 and y = 3:

    A.  (x - 3²).y-6

            (-1 - 9).3-6 = -10 x 3 -6  = -30 - 6 = -36

  B.  (x - 3²)(y-6)

           ( -1 -3²)(3 - 6) = (-1 -9)(-3) = 30

 C.  x - 3² . (y-6) = -1 - 9.(3-6)

                          = -1-9.-3

                          = -1 - 9 x -3

                          = -1 + 27

                          = 26

D. x - 3².y-6 = -1 - 9. 3 - 6

                    = -1 - 27 - 6

                    = -34
