You are correct with all of your answers so far,...

Step-by-step explanation:

5) = 0 (-17 + 20 = 3,... 3 + -3 = 0)

6) = -34 (-34 + 25 = -9,... -9 + -25 = -34)

9) = -4 (7 + -11 = -4)

Chow,...!

Answer:

for question 5 the answer is 0.

for question 6 the answer is -34.

for question 9 the answer is -4.

Step-by-step explanation:

question 5: -17+20 can also be written as 20-17 which is equal to 3. Next, we have to add 3 with -3. 3+(-3) is the same as 3-3 which equals 0.

question 6: 25-25 = 0, and the remainder is -34.

question 9: 7-11 can also be written as -11+7, which is equal to -4.

Try to fill in the missing numbers

Answers

9514 1404 393

Answer:

  [[274][895][136]]

Step-by-step explanation:

Starting with the middle row, we need a product of two single-digit numbers that is between 53-1 = 52 and 53-9 = 44. Possible products are 5×9=45 and 6×8=48. This means the number in the middle position in the left column must be 8 or 5.

The middle number in the left column cannot be 5, because we must be able to get -5 by subtracting that number from a sum that is at least 3 = 1+2. So, the middle number in the left column is 8, the other two numbers in that column are 1 and 2, and the other two numbers in the middle row are 5 and 9.

There is no product of single-digit numbers that is 30-1 = 29, so the upper left number must be 2, and the bottom left number must be 1. The other two numbers on the top row must be 4 and 7, so that row's equation is 2+4×7=30.

The only remaining digits are 3 and 6. In order to have -3 on the bottom row, the equation there must be 1×3-6 = -3. Then the middle digit must be divisible by 3, so must be 9.

Our solution is ...

row 1: 2 + 7 × 4 = 30

row 2: 8 + 9 × 5 = 53

row 3: 1 × 3 - 6 = -3

And that makes the column equations be ...

col 1: 2 - 8 + 1 = -5

col 2: 7 + 9 / 3 = 10

col 3: 4 × 5 - 6 = 14

For this item, any non-integer answer should be entered as a decimal, rounded to the hundredths place.


Triangle ABC has coordinates A(-4,1), B(0,-2),and C(4,1).

The perimeter of ∆ABC is ___ units.

Answers

9514 1404 393

Answer:

  18 units

Step-by-step explanation:

The distance formula is used to find the distance between two points:

  d = √((x2 -x1)² +(y2 -y1)²)

For AB, the distance is ...

  d = √((0 -(-4))² +(-2 -1)²) = √(16 +9) = √25 = 5

The distances between the other pairs of points can be found the same way. We have elected to let a spreadsheet do the math. It tells us the perimeter of triangle ABC is 18 units.

the larger lf ferret food is on sale at the super pet mart 89. Ferroza made the following table. Explain to ferroza why the cost of food at super pet mart is not a proportional relationship

Answers

Proportional relationships are relationships that can be represented using a uniform or constant rate. The cost of food is not a proportional relationship because it does not use a uniform rate.

The missing table is as follows:

[tex]\begin{array}{cc}Bag&Cost\\0&0\\5&17.5&30&89\end{array}[/tex]

Let:

[tex]x \to[/tex] Bag

[tex]y \to[/tex] Cost

First, we calculate the slope (m) of the table using:

[tex](x_1,y_1) = (0,0)[/tex]

[tex](x_2,y_2) = (5,17.5)[/tex]

The slope (m) is as follows:

[tex]m=\frac{y_2 - y_1}{x_2 - x_1}[/tex]

[tex]m=\frac{17.5 - 0}{5-0}[/tex]

[tex]m=\frac{17.5}{5}[/tex]

[tex]m=3.5[/tex]

Also, calculate the slope (m) using the following points

[tex](x_1,y_1) = (0,0)[/tex]

[tex](x_2,y_2) = (30,89)[/tex]

The slope (m) is as follows:

[tex]m=\frac{y_2 - y_1}{x_2 - x_1}[/tex]

[tex]m = \frac{89 - 0}{30 - 0}[/tex]

[tex]m = \frac{89}{30}[/tex]

[tex]m = 2.97[/tex]

The calculated slopes are not the same. i.e.

[tex]3.5 \ne 2.97[/tex]

Hence, the cost of food is not a proportional relationship because it does not use a uniform rate.

By the triangle angle-sum theorem, all the angles of a triangle have to add up to equal 180°.  Thus,

72° + 5x° + x° = 180° and

72° + 6x° = 180° and

6x° = 108° so
