The compound inequality for the temperature T of a refrigerator that is at least 35°F and at most 41°F is 35  ≤  T ≤  41

A compound inequality has two inequality statements joined together

The the temperature of the inequality is represented by T

The temperature T of a refrigerator is at least 35°F and at most 41°F

This means that the temperature falls between 35°F and 41°F

Since the temperature, T, is at most 41°F

This can be mathematically interpreted as

T  ≤  41

The temperature, T, is at least 35°F

35  ≤  T

Combining the two inequality statements 35  ≤  T and T  ≤  41, the compound statement formed is:

35  ≤  T ≤  41

The compound inequality for the temperature T of a refrigerator that is at least 35°F and at most 41°F is 35  ≤  T ≤  41

(C) 7+2√10

Answer:

correct the answer is 6.13

Step-by-step explanation:

The required current balance in Maggie's bank account is 6.13.

Given that,
Maggie has a bank account balance of -18.37 as soon as she realizes this she deposits 24.50 in the account.

In mathematics, it deals with numbers of operations according to the statements. There are four major arithmetic operators, addition, subtraction, multiplication and division,

here,
initial balance in Maggies's bank account = -18.37
She deposited 24.50 in her bank account,
The current balance in her bank account = Initial balance + money deposited
Current = 24.50 - 18.37
Current balance = 6.13

Thus, the required current balance in Maggie's bank account is 6.13.

Answer:

2064 g, 21.3 lb, 452 oz, 16.7 kg

Step-by-step explanation:

Let's change all units to grams to be able to compare the amounts.

21.3 lb * 454 g / lb = 9,670.2 g

2064 g = 2064 g

16.7 kg * 1000 g / kg = 16,700 g

452 oz * 1 lb / 16 oz * 454 g / lb = 12,825.5 g

From least to greatest:

2064 g, 21.3 lb, 452 oz, 16.7 kg

Step-by-step explanation:

A=3 3/4×1 1/2

A=5.625

Answer:

-7

Step-by-step explanation:

A. I would suggest including all units in your answer. Both answers are correct but the unit is also important.

average rate of change:

($750 - $350) / (2014 - 2010) = $400 / (4 years) = $100 per year

initial value:

$350

B. Take 2010 to be year 0. Then for year x = 0, the fee is y = $350.

If the fee increases at a rate of $100 per year, this means that when x = 1, y = $350 + $100 = $450. So the graph of the function that models the dog-walking fee is a line that passes through the points (0, 350) and (1, 450), adn the slope of this line is

(450 - 350) / (1 - 0) = 100/1 = 100

which is the same as the average rate of change.

Using the point-slope formula for a line, the equation you want is then

y - 350 = 100 (x - 0)

y - 350 = 100x

y = 100x + 350

Rotate 180 degrees about the origin

X(x,y) ====> X'(-x,-y)

K(-5 , - 9) = K ' (- -5, - - 9)

K' (5,9)

3 Units Left.

y is unchanged.

x becomes x - 3

K'(5,9) ===>k" (5 - 3,9)

k"(2,9)

The leftward motion does not look done the same way as moving a parabola left. But you are just changing the x value to move a point left. You are not imposing other rules on the figure.

Answer:

  (c)  y = 3x +2

Step-by-step explanation:

The second given point is the y-intercept, telling you that the 'b' in the equation y = mx +b is 2. This eliminates the first and last choices.

Trying the other point in the two remaining equations shows you which one works:

  (b)  y = -3x +2

     -1 = -3(-1) +2 . . . . not true

  (c)  y = 3x +2

     -1 = 3(-1) +2 . . . . true

The equation of the line through the two points is ...

  y = 3x +2

_____

Additional comment

If you plot the two points, you see the line connecting them must have a positive slope. Only the third choice has a positive slope and a y-intercept of 2.

Answer:

Step-by-step explanation:

EFD = 90* (straight line = 180, and other angle is 90)

EHF = 180-52 = 128* (again straight line)

HFG = 90-32 = 58* (its a right angle (can tell by the square angle) = 90*)

G = 180 - 52 - 58 = 70* (angles in triangle = 180)

E = 180 - 32 - 128 = 20* (angles in triangle = 180)

Answer:

x = 10

Step-by-step explanation:

The exterior angle of a triangle is equal to the sum of the 2 opposite interior angles.

12x + 15 is an exterior angle of the triangle , then

12x + 15 = 4x + 10 + 85 , that is

12x + 15 = 4x + 95 ( subtract 4x from both sides )

8x + 15 = 95 ( subtract 15 from both sides )

8x = 80 ( divide both sides by 8 )

x = 10
