Answers

Answer:

  38

Step-by-step explanation:

You want the value of the expression -ab³ -ac for (a, b, c) = (-2, 3, -8).

Evaluation

Put the values where the corresponding variables are and do the arithmetic.

  -ab³ -ac = -(-2)(3³) -(-2)(-8) = 2·27 -16 = 54 -16 = 38

The shortest side of a right triangle measures 6, and the longest side measures 10. Determine the measurement of the unknown side.
A. 5
B. 8
C. 9
D. 10

Step-by-step explanation: find the numbers squared and subtract the shorter side from the longest; 100-36=64 then you find the square root of that which is 8

Its B=8 because every triangle

A rectangle is 5 inches long and 2x inches wide. The value of the perimeter (in inches) is equal to the value of the area (in square inches). Find x.

Answers

Let y equal both the perimeter and the area. So, the equation for the perimeter is 5 plus 5 plus 2x plus another 2x equal to y. And 5 times 2x is equal to y for the area. That makes 10 plus 4x equal to 10x.
Subtracting 4x from both sides of the equation results in 10 equals 6x. Dividing both sides by 6 results in x equaling 10/6 or 5/3

Which of the following is equivalent to 5a + 2b + 6c?

13abc
7ab + 6c
5a + 8bc
2b + 5a + 6c

Answers

There is no multiplication here, and there are also no like terms, so terms with different variables cannot be combined due to the lack of multiplication. This expression cannot be simplified, only rearranged. Therefore, expressions that appear to simplify it:

13abc
7ab + 6c
5a + 8bc

Are not equivalent. Therefore:

2b + 5a + 6c, which only rearranges the expression, is equivalent.

Answer: 2b + 5a + 6c

Step-by-step explanation: The Equivalent expressions of the given expression is a 2b + 5a + 6c. Thus, option D is a correct.

According to the statement

We have to find that the equivalent expression.

So, For this purpose, we know that the

Equivalent expressions are expressions that work the same even though they look different.

From the given information:

The given expression is a 5a + 2b + 6c

Then

1) 13abc

It is completely different from the 5a + 2b + 6c

2) 7ab + 6c

It is also completely different from the 5a + 2b + 6c

3) 5a + 8bc

It is also completely different from the 5a + 2b + 6c

4) 2b + 5a + 6c

It is sams as the  5a + 2b + 6c because of the some same coefficients of the variables.

So, The Equivalent expressions of the given expression is a 2b + 5a + 6c. Thus, option D is a correct.

20 POINTSSSSSSSSSSSSSSSSSSSSS do these pairs of values (x and y) represent two quantities that are proportional x 1, 4,10,18 y 3, 8, 15, 27, A. no, because mot all pairs represent the same ratio. B, yes, because all of the pairs represent the same ratio. C. yes, because as x increases y increases. D. no, because not all of the x-values can be divided by 2 evenly

Answers

Answer:Answer: B) No, because not all of the pairs represent the same ratio

For each row, divide y over x

Row 1:  y/x = 5/3 = 1.67 approximately

Row 2: y/x = 7.4 = 1.75

Row 3: y/x = 10/6 = 1.67 approximately

Row 4: y/x = 15/9 = 1.67 approximately

We see that row 2 has a ratio different from the others. If we were able to ignore this row, then the answer would be "yes x and y are proportional". However, we cannot ignore this row so that's why the answer is choice B.

bananas.
a. Round each price to the nearest whole dollar. Then estimate how much
money she spent on each type of fruit. Fill in the blank.
Type of Fruit Cost Rounded Cost per pound Estimated Total
apple $1.75/pound
orange $2.35/pound
banana $1.50/pound

b. About how much money did Annie spend in all?

c. How much money did Annie actually spend? Complete the equation to
show the amount of money that Annie spent. Was your estimation
more or less than the actual amount? Why do you think that might be? Fill in the blank.

Answers

A.

Apples- About $10/pound

Oranges- About $8/pound

Bananas- About $6/pound

B.

Annie spent about $24 in total.

C.

(1.75 X 5) + (2.35 X 4) + (1.50 X 3) = 22.65 (dollars)

My estimation was more than the actual amount. I think that the estimation was more because most of the unit prices had to be rounded up, not down.

Ansley and Maria were baking a birthday cake. The recipe called for 2 3/4 cup of flour. Both girls took turns pouring in the flour. Maria poured in 1 2/4 cup of flour into the mixing bowl and then Ansley poured in the remaining amount.

Which of these equations BEST tells how to identify the amount of flour Ansley poured into the mixing bowl?
A- 11/4 - 5/4 = 6/4
B- 11/6 - 6/4 = 5/4
C- 1 2/4 + 2 3/4 = 4 1/4
D- 6/4 + 5/4 = 11/4

Answers

Answer:

Answer: Flour is the ingredient you need the most as it is 21/3 = 7

baking soda is the ingredient you need the least as it is 2/3 = 0.6

A- 11/4 - 5/4 = 6/4

The recipe needs 2 3/4 in total so you need to subtract 1 2/4 from it. You can do this by using the improper fractions 11/4 for 2 3/4 and 5/4 for 1 2/4.

Y is 2 Up X is 1 To the Right

Answer:

  y = 4/3x +2

Step-by-step explanation:

You want a linear function that relates y to x as shown in the graph.

Linear function

A linear function can be written in slope-intercept form as ...

  y = mx + b . . . . . . line with slope m and y-intercept b

Slope

The slope is the ratio "rise"/"run". Each of these can be found by counting grid squares where the line crosses grid points.

The point on the y-axis is on a grid intersection, and the point at the top with coordinates (6, 10) is also on a grid intersection. There are 4 vertical squares between these points, and 3 horizontal squares. This means the slope is ...

  m = rise/run = 4/3

Y-intercept

The line crosses the y-axis on the grid line that would be labeled 2. So, b=2 in our equation of the line.

Function

The desired linear function is ...

  y = mx +b

  y = 4/3x +2

__

Additional comment

You can also find the slope between two points using the slope formula:

  m = (y2 -y1)/(x2 -x1)

For points (0, 2) and (6, 10), the slope is ...

  m = (10 -2)/(6 -0) = 8/6 = 4/3 . . . . . . as above

Howard has a garden in the shape of a rectangle.
The length is 5.4 meters.
The width is 1.5 meters.

Howard will increase both the length and the width by 20% each.

Part A: What will be the perimeter, in meters, of the enlarged garden?

Part B: By how many square meters will the area of the garden increase?

Answers

Part A: P = 16.56m
Part B: 3.56m^2 increase

Step-by-step explanation:

The actual length of 5.4 is increased by 20%.

-  (20/100) × 5.4

-  0.2 × 5.4

-  1.08

Part A- 5.4 + 1.08 = 6.48 meters.

The actual width of 1.5 is increased by 20%.

-  (20/100) × 1.5

-  0.2 × 1.5

- 0.3

Part B- 1.5 + 0.3 = 1.8 meters

The perimeter of the enlarged rectangle is seen by replacing the enlarged values of length and width in the perimeter formula.

(       2 (length + width)  )

-   2 (6.48 + 1.8)

-   2 × 8.28

-   16.56 meters.
