8+(2+6)=(8+2)+6 what property justifies that statement

Answers

Answer 1

Answer:

Associative Property of Addition

Step-by-step explanation:

According to the Associative Property of Addition, when three real numbers are added, it makes no difference which two are added first.

(a + b) + c = a + (b + c)

Therefore, 8 + (2 + 6) = (8 + 2) + 6 is an example of the Associative Property of Addition.

Charlotte buys a ticket to go to a baseball game. The total includes a charge of​ 7% of the original price for extra fees. If Charlotte pays a total of​ $44.94, how much was the original price of the​ ticket?

Answers

Answer:

$41.7942

Step-by-step explanation:

First you need to change 7% into a decimal (you do this by dividing it by 100)

7÷100=0.07

Then, you multiply 0.07 with 44.94

0.07×44.94=3.1458

3.1458 is the amount for the extra fees.

After that, you subtract 44.94 with 3.1458

44.94-3.1458=41.7942

This gives us the original price, so, the original price is $41.7942.

You go to Ihop and order two servings of pancakes and a
-cup of coffee. The cost of the coffee is $2.00. You leave a
20% tip. The total bill is $14.40. How much does one serving
of pancakes cost?

Answers

Answer: $4.76

To find the answer you need to find out the total before the 20% tips to find this you need to subtract 14.40 and 20% which = $11.52.If the coffee was $2 you also need to subtract that so the equation would be (11.52-2.00=9.52).Lastly the question is asking you for the price of one serving of pancakes but we have the answer for 2 which is $9.52.To find the price of of 1 serving you need to divide $9.52 by 2 = $4.76.So your answer is $4.76 for 1 serving of pancakes.

1. How many triangles are created in the following situation:

Answers

Answer:

Step-by-step explanation:

We can use:

[tex]\frac{12}{sin35} = \frac{16}{sinB}[/tex]

Solve for sinB

[tex]sinB=\frac{16(sin35)}{12}[/tex]

The answer we get from that is: 0.76

With that answer, we can do:

[tex]B=sinx^{-1}(0.76)[/tex]

So, since the calculator did NOT put out an error, there is 2 such triangles.  

Only 1 triangle can be formed by angle m∡A = 35°, a = 12, b = 16.

How many triangles are created in the following situation:m∡A = 35°, a = 12, b = 16. is to be determined.

What is the triangle?

The triangle is a geometric shape that includes 3 sides and the sum of the interior angle should not be greater than 180°.

Here, the data given is m∡A = 35°, a = 12, b = 16,
Since one angle m∡A = 35° is given between the two sides a = 12, b = 16,.
There is only one triangle that can be made through the given data.
because when we plot the measures only one side can be added without calculation in order to complete the triangle.

Thus, only 1 triangle can be formed by m∡A = 35°, a = 12, b = 16.

The width of a rectangle is 3 yards less than its length. The perimeter is 130 yards. Find the length and width of the rectangle.

Answers

2(L-3)+2L=130
2L-6+2L=130
4L=136
L=34 W =31

Answer:

Length = 34 yards

Width = 31 yards

Step-by-step explanation:

Perimeter = 2(l + w), where l = length, and w = width

We know that w, is l - 3

130 = 2(l + l - 3)

130 = 4l - 6

136 = 4l

l = 34

Width is 3 less than 34, or 31

find the number which when divided by 2/5 will give 30






Answers

Answer:

The answer is 12. 12 divided by 2/5 will give us 30.

Step-by-step explanation:

To find this, simply do the opposite of dividing. Simply multiply 2/5 by 30, and you'll have your answer.

First, before we do this, however, we are going to find out what the decimal form of 2/5 is. To do this, divide the numerator by the denominator. In this case, 2 is the numerator and 5 is the denominator. So divide 2 by 5.

This gives us 0.4. So 2/5 in decimal form is 0.4. Now multiply 0.4 by 30 to find your answer.

30*0.4=12

So the answer is 12. However, rememeber that you always need to check your work. So lets check.

12/30=0.4

0.4=0.4

Do we get a true statement? Yes, so we are correct.

The number you are looking for is 75.

To find the number that, when divided by 2/5, gives 30, we can set up the following equation:

x / (2/5) = 30

To solve this equation, we can multiply both sides of the equation by the reciprocal of 2/5, which is 5/2:

x = 30(5/2)

Simplifying the right side of the equation:

x = 150/2

Dividing 150 by 2:

x = 75

Therefore, the number you are looking for is 75.

If necessary, round your answer to two decimal places, like this: 42.53

Answers

Answer:

EF = 1.98

Step-by-step explanation:

Sin = opposite/hypotenuse; Cos = adjacent/hypotenuse ;

Tan = opposite/adjacent

DF = 4.5 which is the hypotenuse.  So using the equation for Sin

 Sin 26° = opposite/hypotenuse

  Sin 26° = EF/4.5

  .44 = EF/4.5   solving .44(4.5) = EF ;  1.98 = EF
