Step-by-step explanation:

the 8 is repeating

Answer:

Step-by-step explanation:

Answer:

In order to solve these, you must combine your variable terms and move them till they are isolated from your constants. Divide until the variable is alone on one side.

Answer:

1. 7

Step-by-step explanation:

1. 8y= 37+ 35

Subtract 3y from both sides of the equation:

8y - 3y = 3y + 35 - 3y

simplify:

combine like terms

than combine like terms again

5y= 35

Divide both sides of the equations by the same term:

5y = 35

[tex]\frac{5y}{5} = \frac{35}{5}[/tex]

simplify:

cancel terms that are in both the numberator and denominator

divide numbers

Answer:

[tex]x=\dfrac{d}{(5+10f)}[/tex]

Step-by-step explanation:

The given equation is :

d = 5x + 10xf

We need to solve the above equation for x.

Taking x common from RHS,

d=x(5+10f)

Dividing both sides by (5+10f),

[tex]x=\dfrac{d}{(5+10f)}[/tex]

Hence, this is the required value of x.

Answer:

-44

Step-by-step explanation:

So you want to plug 2 in for t, so the equation should now look like:

[tex]2^{2}[/tex] - 44 - 4

No all you have to do is solve

[tex]2^{2}[/tex] = 4

4 - 44 = -40

-40 - 4 = -44

Answer:

-44

Step-by-step explanation:

t=2, t² - 44 - 4

1. substitute in the value to the variable: 2² - 44 - 4

2. using PEMDAS, solve the equation: 2² - 44 - 4 = 4-44-4 = -40-4= -44

(evaluate the exponent, then subtract)

Answer:

d= 17.03

Step-by-step explanation:

[tex]d=\sqrt{ (x_{2}-x_{1})+(y_{2}-y_{1})^{2}}\\\\d=\sqrt{(8--3)+(-6-7)^{2}}\\\\d=\sqrt{(11)+(-13)^{2}} \\\\d=\sqrt{121+169}\\\\d= \sqrt{290} \\\\d=17.03[/tex]

Hi there!

The domain is:

20<=x<=40

Step-by-step explanation:

This states that:

x>=20

x<=40

Which fits the problem!

Hope this helps

For a given function f(x) we define the domain as the set of possible values of x that we can use in the function.

Here we will find that the domain is D: [20h, 40h]

We know that Ally wins $18 per hour, and she has two restrictions:

She cant' work more than 40 hours.

She needs to work at least 20 hours.

Then her weekly salary can be written as:

s(x) = $18*x

Where x is the number of hours that she works each week.

With the above restrictions we have:

20h ≤ x ≤ 40h

Then the domain is:

D: [20h, 40h]

What is the question??

Step-by-step explanation:

I am confused.

Answer:

6 seconds

Step-by-step explanation:

Initial distance of Mario from motion detector = 2 ft

Speed of Mario = 1.5 ft/sec

Total distance of Mario from motion detector = 11 ft

Total distance moved by Mario while walking at the rate of 1.5 ft/sec = 11 - 2 = 9 ft

Given that:

Distance = 9 ft

Speed = 1.5 ft/sec

Formula:

[tex]Distance = Speed \times Time[/tex]

[tex]\Rightarrow 9 =1.5 \times Time\\\Rightarrow Time = \dfrac{9}{1.5}\\\Rightarrow Time = \bold{6\ sec}[/tex]

So, at 6 seconds, Mario will be 11 ft from the motion detector.

Answer:

Probability that the whole shipment will be accepted = 0.9660

96.60% of the shipment will be accepted

Almost all the shipments will be accepted

Step-by-step explanation:

We are given;

n = 41

p = 3% = 0.03

x = 3

This is a binomial probability question and we will use the formula;

P(X = x) = [n!/(x!(n - x)!)] × p^(x) × (1 - p)^(n - x)

The probability that the whole shipment will be accepted is given by the form;

P(X ≤ 3) = P(0) + P(1) + P(2) + P(3)

P(3) = [41!/(3!(41 - 3)!)] × 0.03³ × (1 - 0.03)^(41 - 3)

P(3) = 0.09046

P(2) = [41!/(2!(41 - 2)!)] × 0.03² × (1 - 0.03)^(41 - 2)

P(2) = 0.22496

P(1) = [41!/(1!(41 - 1)!)] × 0.03¹ × (1 - 0.03)^(41 - 1)

P(1) = 0.36373

P(0) = [41!/(1!(41 - 0)!)] × 0.03^(0) × (1 - 0.03)^(41 - 0)

P(0) = 0.28684

Thus;

P(X ≤ 3) = 0.28684 + 0.36373 + 0.22496 + 0.09046

P(X ≤ 3) = 0.96599 ≈ 0.9660

It means that 96.60% will be accepted

The answer is either5x+3 = 4x-3

Answer:

x = -27

Step-by-step explanation:

5 ( x + 3 ) = 4 ( x - 3 )

5 times x, 5 times 3, 4 times x, 4 times -3 =

5x +15 = 4x -12

Subtract 15

5x +15 -15 = 4x -12 -15=

5x = 4x -27

Subtract 4x

5x -4x = 4x -4x -27 =

1x = -27

Divide

1x/1 = -27/1 =

x = -27
