Answer:

No.

Step-by-step explanation:

An integer is a positive or negative whole number. Because -199.46 is a decimal, it is not an integer.

Answer: No

Step-by-step explanation: An integer is a whole number that isn't a fraction, or a number that isn't a fraction. Fractions and decimals are not included in the set of integers, so no, -199.46 is not an integer.

Answer:

80%

Step-by-step explanation:

The diagram all together equals 100%, break it up into 5 groups 20,40,60,80,100. You have 4 out of 5 filled in so you answers 80%.

Given the function,

[tex]t(v) = \sqrt{ {v}^{2} + 2v - 8 } [/tex]

We are aware that square root function is defined for only non negative values.

So,

[tex]\to {v}^{2} + 2v - 8 \geqslant 0[/tex]

[tex] \to{v}^{2} + 4v - 2v- 8 \geqslant 0[/tex]

[tex]\to {v}(v + 4) - 2(v + 4) \geqslant 0[/tex]

[tex]\to(v + 4)(v - 2) \geqslant 0[/tex]

Therefore,

[tex]\boxed{\red{v\in (-\infty, -4] \cup [2,\infty})} [/tex]

Since this is the possible input values of v for which the given function is defined, it is the domain of the function.

Answer:

13

Step-by-step explanation:

Since the angles form 180 degrees, it will be what the equation is equal to.

Make the equation:

8r + 5 + 5r + 6 = 180

Combine like terms:

8r + 5 + 5r + 6 = 180

13r + 5 + 6 = 180

13r + 11 = 180

Solve:

13r + 11 = 180

       -11     -11

---------------------

     13r = 169

    ------   ------

      13      13

Answer:

108 cm²

Step-by-step explanation:

Area of a rectangle, A = length, l × width, w

Perimeter of a rectangle = (2 × length) + (2 × width)

42 cm = 2l + 2w

but length = w + 3cm

42 cm = 2(w + 3cm) + 2w

42 cm = 2w + 6cm + 2w

42 cm = 6cm + 4w

4w = (42 - 6) cm

4w = 36 cm

》w = 9cm

》l = w + 3cm = 9cm + 3cm

l = 12 cm

Area = 12 × 9 = 108 cm²

Answer:

  A

Step-by-step explanation:

It is generally useful to look at the answer choices. Here, we observe that all of them have y with a positive coefficient on the left side of the inequality. This makes it relatively easy to choose the set of inequalities that matches the graph.

The shading is below the solid line and above the two dashed lines. This means we are looking for a set of inequalities that looks like ...

  ay + ( ) ≤ ( ) . . . . . shading below a solid line

  y + ( ) > ( ) . . . . . . shading above a dashed line

  y + ( ) > ( )

The only set of inequalities with these relationships is choice A.

if he uses 1/2 for 2/3, then you can divide 2/3 and 1.2 by 2 to get the remaining soap needed to complete the wash

so to clean the last 1/3 of the car, he`ll use 1/4 of the remaining soap

the entire car needs 3/4 of a bottle of soap

The slope is -2. In context to this problem, the candle will burn away 2cm of its length every hour.

The slope of the equation, -2, means that the height of the candle reduces at a rate of 2 cm per hour.

Given the linear equation of the height of a candle that has been burning as: [tex]h = 28 - 2t[/tex].

This implies that:

28 in the equation represents the initial height of the candle = 28 cm.

-2 in the equation is slope, which is the rate of change at which the candle burns, meaning the height of the candle reduces by 2 cm every hour.

Therefore, the slope of the equation can be interpreted in the context of the problem as:

for every hour that passes, the height of the candle reduces by 2 cm.
