help me please. Solve for x

Answer:

P = -5

Step-by-step explanation:

First try to get the variable p by its self and the whole numbers on the opposite side.

14p - 8 = 22 + 20p

-14p                - 14 p

-8 = 22 + 6p

-22  -22      

-30 = 6p

Then divide to get P alone

-30 = 6p

/6        /6

-5 = p

Step-by-step explanation:

Add 1 and subtract 1, so that the expression won't change.

[tex]x^{4}+\frac{1}{x^{4}}-3=x^{4}+\frac{1}{x^{4}}-3 +1 - 1\\\\=x^{4}+\frac{1}{x^{4}} - 2 + 1\\\\= (x^{2})^{2} + (\frac{1}{x^{2}})^{2}- 2 *x^{2}*\frac{1}{x^{2}} - 1\\\\[/tex]

Answer:

1 in : 27 yd

Step-by-step explanation:

4 in : 108 yds

108/4=27

so the ratio would be

1 in : 27 yd

Answer:

28.26

Step-by-step explanation:

3×3=9

9×3.14=28.26

Answer:

The answer is 28.26

Step-by-step explanation:

Why? Ok so here it is:

The formula is (pi)(r)squared

In this case, you will replace pi with 3.14 and replace r with 3 because that's the radius.

So it would be (3.14)(3)

You would get 9.42

Now you just need to square it

When squared, you'll get 28.26 inches squared

Step-by-step explanation:

Is your algebra expression

Answer:

a) C = 3 + 5h

b) Slope = 5

y - intercept = 3

c) $28

Step-by-step explanation:

For babysitting, Nicole charges a flat fee of $3, plus $5 per hour.

a) Write an equation for the cost, C, after h hours of babysitting.

The equation for the cost C is given as:

C = $3 + $5 × h

C = 3 + 5h

b) What do you think the slope and intercept represent?

The equation of a straight line is represented by

y = mx + c

Where

Slope = m and y-intercept = c

Comparing this with our equation in a

C = 3 + 5h = C = 5h + 3

mx = 5h

c = 3

Therefore,

Slope = 5

y - intercept = 3

c)How much money will she make if she baby-sits 5 hours?

We have our equation above as:

C = 3 + 5h

h = 5 hours

Hence,

C = 3 + 5 × 5

C = 3 + 25

C = $28

She would make $28

Answer:

A

Step-by-step explanation:

Answer:

1. State the claim H0 and the alternative, Ha

2. Choose a significance level or use the given one.

3. Draw the sampling distribution based on the assumption that H0 is true, and shade the area

of interest.

4. Check conditions. Calculate the test statistic.

5. Find the p-value.

6. If the p-value is less than the significance level, α, reject the null hypothesis. (There is enough

evidence to reject the claim.)

If the p-value is greater than the significance level, α, do not reject the null hypothesis.

(There is not enough evidence to reject the claim.)

(You can use the p-value to make a statement about the strength of the evidence against H0

without using α, e.g., p>.10 implies “little or no evidence against H0”, .05< p ≤ 10 implies

“some evidence against H0”, .01 < p ≤ .05 implies “good evidence against H0”, .001 < p ≤ .01

implies “strong evidence against H0”, p ≤ .001 implies “very strong evidence against H0”.)

7. Write a statement to interpret the decision in the context of the original claim.

Answer: 0.2 m/s

Step-by-step explanation:

The student steps on the raft, and then he moves (with the raft) at a speed of 2.0m/s to cross the flooded street.

Then the raft moves with him, at the same speed (notice that the mass of the raft does not matter, suppose that you move at 100km/h in a small car, the speed of the vehicle would be exactly the same as if you where in a truck moving at 100km/h)

Then the speed of the raft is also 2.0 m/s.

Answer:

A. All seventh grade students at Wood Middle School

Step-by-step explanation:

We want to find which is the population.

Now, A population is simply the entire set or group that you intend to find out information and draw up a conclusion while sample is the specific set or group derived from that population from which we collect data.

Thus implies that the population size is always more than the sample size.

In this question, from the definition we have given, we can easily see that the population is the 300 seventh grade students at Wood Middle School while the sample is is the 100 seventh grade students that were surveyed.

37.5% esa es la respuesta correcta

Answer:

37.5%

Step-by-step explanation:

Answer:

B. 60deg

Step-by-step explanation:

Both the sum of the third angle in the triangle and x has to be 180deg, as they sum to a half angle;

and the sum of angles in any triangle is 180deg.

We know that x = 180deg - (180deg - 28deg - 32deg) = 180deg - 180deg + 28deg + 32deg = 60deg

Also, note that x is drawn as smaller than a right angle. Unless the picture was made specifically to confuse us, we know that the only answer could be B.

Answer:

The exterior angle measures 60°

Step-by-step explanation:

Using the angles we already have we can determine that the missing interior angle is 120 since the interior angles of a triangle add up to 180°. So the missing interior and and the missing exterior angle are supplementary meaning they add up to 180. so 180-120=60°

Answer:

20 inches

Step-by-step explanation:

A rectangular object can instead be thought about as two right triangles with the hypotenuse being the diagonal we are solving for.

With this in mind the Pythagorean Theorem can be used to solve for c

c^2=a^2+b^2

A=16 inches

B= 12 inches

C= hypotenuse

C^2=16^2+12^2

C^2=256+144

C^2=400

Take the square root of both sides: C = 20 inches

Answer:

30 tiles need to buy for same cost in both store.

Step-by-step explanation:

Let x be the number of tiles to buy for same cost in both store.∴18+0.69⋅n=1.29⋅n∴ 1.29n − 0.69n = 18 or 0.6n =18∴n=180.6=30 Therefore, 30 tiles need to buy for same cost in both store
