TRUE OR FALSE

The associative property for addition is used in adding and subtracting numbers in expanded form.

Choices:

A) The statement is false because it is the commutative property that is​ used, not the associative.

B) The statement is true.

C) The statement is false because it is the distributive property that is​ used, not the associative.

D) The statement is false because it is the reflexive property that is​ used, not the associative.

Answer:

x = 9.5

this should be the right answer if the same one you had to solve.

Step-by-step explanation:

y = 2x - 4

y = 12 + 3                             combine them

2x - 4 = 12 + 3

    +4         +4                   The 4's cancel each other out

2x = 12 + 7                     Add then divide

 2x = 19

  2x = 19

  ----   ----

Answer:

The time it would take to fill up the truck is approximately 344 minutes

Step-by-step explanation:

The given parameters of the truck are;

The volume of the water truck, V = 1,200 gallon

The rate at which water flows from the hose. m = Constant rate

The volume of water in the truck after t₁ = 10 minutes is V₁ = 65 gallons

The volume of water in the truck after t₂ = 15 minutes is V₂ = 82 gallons

Therefore, the rate at which water flows from the hose to the truck, 'm', is given by the equation for the slope of a straight (constant variation) line, as follows;

[tex]m = \dfrac{V_2 - V_1}{t_2 - t_1}[/tex]

Therefore, we have;

[tex]m = \dfrac{82 \, gallons - 65 \, gallons}{15 \, minutes - 10 \, minutes} = 3.4 \, gallons/minute[/tex]

The point and slope form of the straight line equation relationship between the volume in the tank and the time of flow is given as follows;

V - 82 = 3.4 × (t - 15)

Therefore, the slope and intercept form of the equation is given as follows;

V = 3.4·t - 15 × 3.4 + 82 = 3.4·t + 31

∴ V = 3.4·t + 31

When the tank is filled, V = 1,200 gallons, therefore, we have;

1,200 = 3.4·t + 31

3.4·t = 1,200 - 31 = 1,169

t = 1,169/3.4 = 5845/17 = 343.[tex]\overline{8235294117647058}[/tex]

The time it would take to fill up the truck, t = 343.[tex]\overline{8235294117647058}[/tex] minutes ≈ 344 minutes.

Answer:

Decision is to fail to reject the null hypothesis.

Step-by-step explanation:

Since our significance level is α = 0.05, but since it's a two tailed test for two proportions, in each tail, we will have 0.05/2 = 0.025.

Now, the rejection region will be the critical value at 1 - 0.025 = 0.975

From the z-table attached, the critical value at 0.975 is 1.96.

Thus, our decision rule will be;

If Z-score is less than -1.96, or greater than 1.96, we will reject the null hypothesis.

Now, we have a z-score of z = 1.946 in the question. This lies between -1.96 and 1.96.

Thus,we will fail to reject the null hypothesis

Answer:

x = 23

y = 105

Step-by-step explanation:

It's given that lines 'k' and 'm' are the parallel lines and 'l' is a transversal line.

Therefore, y° + 75° = 180° [Sum of consecutive exterior angles = 180°]

y = 180 - 75

y = 105°

And y° + (4x - 17)° = 180° [Linear pair of angles are supplementary]

105 + (4x - 17) = 180

4x + 88 = 180

4x = 180 - 88

4x = 92

x = 23

Answer: -3-5[tex]\sqrt{3}[/tex] / 5

Step-by-step explanation

To write [tex]\sqrt{3}[/tex] as a fraction with a common denominator, multiply by 5/5.

-3/5 + [tex]\sqrt{3}[/tex] * 5/5

Then combine fractions, so that the numeratiors over the common denominator.  

-3 + 5 [tex]\sqrt{3}[/tex] /5

Simplify with factoring out.

Rewrite -3 as -1 (3). Next factor -1 out of 5 [tex]\sqrt{3}[/tex]. Then facotr -1 out of -1(3) - (-5[tex]\sqrt{3}[/tex]). After that move teh negative in front of the fraction.

Exact Form: - 3-5[tex]\sqrt{3}[/tex] / 5

Decimal Form: 1.13

Answer:

x=65°

Step-by-step explanation:

All angles in a triangle add up to 180°

So 180-85-33=62°

90-62=28°

180-87-28=65°

Answer:

x = -0.24 or 3.73

Step-by-step explanation:

[tex]\frac{-b + \sqrt{b^{2} -4ac } }{2a}[/tex] (There's supposed to be a ± between '-b' and the square root)

[tex]x^{2}[/tex] + 4x + 1 ( [tex]ax^{2} + bx + c[/tex] )

a = -1 ( there's no number before [tex]x^{2}[/tex] so its 1 )

b = 4

c = 1

Substitute into the quadratic equation.

[tex]\frac{-4 + \sqrt{4^{2} -4x1x-1 } }{2x-1}[/tex] ( the [tex]x[/tex] is just the multiplication sign )

=  [tex]\frac{-4 + \sqrt{{16} +4 } }{-2}[/tex]

[tex]\frac{-4 + \sqrt{{20} } }{-2}[/tex] = -0.24    [OR]     [tex]\frac{-4 - \sqrt{{20} } }{-2}[/tex] = 3.73

Answer:

the answer would be $128.40

Step-by-step explanation:

7% times 120 is 8.4

8.4 plus 120 is 128.4

The amount to be pay for coat is $128.4

Step-by-step explanation:

Given:The sales tax rate is 7.25% in California.

The cost for a coat in Los angeles is $120.00.

Now, to find amount to be paid.

Sales tax = 7.00%.

Cost = $120.00.

So, amount to be paid = $120 + 7.00% of $120.00.

[tex]=120+\frac{7.00}{100} *120\\=120+\frac{84}{10} \\=120+\frac{42}{5} \\=128.4!![/tex]

Therefore, the amount to be pay for coat is $128.4

Answer:

3x and 8x

Step-by-step explanation:

They both share the same variable unlike 8 and 3y which have different variables. Once simplified, the expression should equal 11x + 8 + 3y

Answer:

3x and 8x

You see 3x and 8x are both like terms because they both have x

but..

The other 3 does not have a x it has a y

Answer:For the cube root function f(x)=3√x f ( x ) = x 3 , the domain and range include all real numbers. Note that there is no problem taking a cube root, or any odd-integer root, of a negative number, and the resulting output is negative (it is an odd function).

Step-by-step explanation:

The domain and range for all cube root functions is set of all real numbers.

The domain and range are defined for a relation and they are the sets of all the x-coordinates and all the y-coordinates of ordered pairs respectively. For example, if the relation is, R = {(1, 2), (2, 2), (3, 3), (4, 3)}, then:

Domain = the set of all x-coordinates = {1, 2, 3, 4}

Range = the set of all y-coordinates = {2, 3}

The domain of a cube root function f (x) = ∛x is the set of all real numbers (R) because it can be calculated for all values of x. Its range is also equal to the set of all real numbers because it will result in all real numbers as y-values.

The range of a cube root function is all real numbers except for 0.

Therefore, the domain and range for all cube root functions is set of all real numbers.
