Answer:

B

Step-by-step explanation:

Given:

The expression is

[tex]8p+3q-18[/tex]

To find:

The value of the expression when [tex]p=\dfrac{1}{2}[/tex] and [tex]q=7[/tex].

Solution:

We have,

[tex]8p+3q-18[/tex]

Putting [tex]p=\dfrac{1}{2}[/tex] and [tex]q=7[/tex], we get

[tex]8(\dfrac{1}{2})+3(7)-18[/tex]

[tex]=4+21-18[/tex]

[tex]=7[/tex]

Therefore, the value of the expression is 7 when [tex]p=\dfrac{1}{2}[/tex] and [tex]q=7[/tex].

Answer:

45 km/h

50 km/h

Step-by-step explanation:

Distance traveled in one way = 450 km

Let x = Velocity when he was going to his destination in km/h

He traveled 5 km/h faster when he returned so his velocity was [tex]x+5[/tex]

It took him 1 hour less when he returned so

[tex]\dfrac{450}{x}-\dfrac{450}{x+5}=1\\\Rightarrow x^2+5x-2250=0\\\Rightarrow x=\frac{-5\pm \sqrt{5^2-4\times 1\times \left(-2250\right)}}{2\times 1}\\\Rightarrow x=45,-50[/tex]

So, velocity while going to his destination is 45 km/h

While returning his velocity was 45+5 = 50 km/h.

Answer:

-3 and 1

Step-by-step explanation:

The zeros of the given function are -3 and 1.

The zeros of a function, also referred to as roots or x-intercepts, are the x-values at which the value of the function is 0 (f (x) = 0). The zeros of a function can be thought of as the input values that result in an output of 0.

Given is a function f(x) = (x + 3)(x - 1)/(x-2)(x + 2),

We need to find the zeros of the function,

Equate to 0,

(x + 3)(x - 1)/(x-2)(x + 2) = 0

Therefore,

(x + 3)(x - 1) = 0

x+3 = 0 and x-1 = 0

Therefore,

x = -3, x = 1

Hence, the zeros of the given function are -3 and 1.

is what the answer should be

Step-by-step explanation:

I'm assuming you mean that <C=68 degrees.

Now we know that the interior angle of a triangle adds up to 180 degrees.

We just need to subtract the 2 already known angles from it.

180 degrees-56 degrees-68 degrees=180 degrees-124 degrees=56 degrees.

Done!

<B=56 degrees.

Any questions you can ask in the comments, also something to look out for always capitalize your letter when you are writing angles :)!

Using the together rate, it is found that it would take each bear 9 hours to open the car door alone.

The together rate is the sum of each separate rate.

In this problem, the rates are as follows:

Hence:

[tex]\frac{1}{x} + \frac{1}{x + 9} = \frac{1}{6}[/tex]

[tex]\frac{x + 9 + x}{x(x + 9)} = \frac{1}{6}[/tex]

[tex]x^2 + 9x - 12x - 54 = 0[/tex]

[tex]x^2 - 3x - 54 = 0[/tex]

Quadratic equation with coefficients [tex]a = 1, b = -3, c = -54[/tex], hence:

[tex]\Delta = b^2 - 4ac = (-3)^2 - 4(1)(-54) = 225[/tex]

[tex]x_1 = \frac{-b + \sqrt{\Delta}}{2a} = \frac{3 + \sqrt{225}}{2} = 9[/tex]

[tex]x_2 = \frac{-b - \sqrt{\Delta}}{2a} = \frac{3 - \sqrt{225}}{2} = -6[/tex]

It would take each bear 9 hours to open the car door alone.

Answer:

4007400000

You move the decimal place to the right 9 places.

Step-by-step explanation:

The required distance around the earth (circumference) in standard form is 40,074,000,000.

A number system is described as a procedure of organizing to express digits. It is the mathematical notation for representing the numbers of a given set by using numbers or other characters in a uniform method. It delivers a special exhibit of every digit and defines the arithmetic structure.

Here,
The number 4.0074 x 10¹⁰ means 4.0074 multiplied by 10 to the power of 10. To convert this number to standard form, we simply need to move the decimal point 10 places to the right.

So the answer in standard form is:

40,074,000,000

Thus, the required distance around the earth (circumference) in standard form is 40,074,000,000.

1. 3 rows with 21 sneakers

2. D. 11*2

Answer:

-10d-4

Step-by-step explanation:

Well, you're in luck because I LOVE distributive property!!!

-4(2d+3) Multiply -4 by 2d to get -8d, and multiply -4 by 3 for -12, so the result would be -8d-12!

Then, 2(-d+4) and therefore 2 times -d (you can just say -1d) to get -2d and 2*4 would be 8 to make -2d+8!

Now you combine them: -8d-12+-2d+8

Combine like terms!

-10d-4 would be your answer.
