in triangleABC the side lengths are b=13, ac=21 and bc=x. write a compound inequality the represents the range of possible values for x

Answers

Answer:

8 < x < 34

Step-by-step explanation:

ab = 13, ac = 21, bc = x

The longest side of a triangle must be less than the sum of the other two sides.

If 21 is the longest side:

21 < 13 + x

8 < x

If x is the longest side:

x < 13 + 21

x < 34

Therefore, 8 < x < 34.

Step-by-step explanation:

You have $4000 to invest. If you'd like to earn exactly $638
in interest each year, how much should you invest in each of
two accounts, one that earns 8% per year and one that
earns 21% per year. (Round your answer to the nearest
dollar)
8%: $
21%: $

Answers

Answer:

8%: $1554

21%: $2446

Step-by-step explanation:

This is a simple interest problem.

The simple interest formula is given by:

[tex]E = P*I*t[/tex]

In which E are the earnings, P is the principal(the initial amount of money), I is the interest rate(yearly, as a decimal) and t is the time.

After t years, the total amount of money is:

[tex]T = E + P[/tex].

In this question:

Two earnings, that i am going to call A(8% per year) and B(21% per year).

Two principals, for A i am going to call P and for B it is the rest, so 4000 - P.

A:

One year, so [tex]t = 1[/tex]

8% interest, so [tex]r = 0.08[/tex]

Earnings A.

[tex]A = P*I*t[/tex]

[tex]A = 0.08P[/tex]

B:

21% interest, so [tex]r = 0.21[/tex]

Principal (4000 - P).

[tex]B = P*I*t[/tex]

[tex]B = 0.21*(4000 - P)[/tex]

You'd like to earn exactly $638 in interest each year.

This means that [tex]A + B = 638[/tex]

Then

[tex]B = 638 - A[/tex]

Now we have to solve the following system:

[tex]A = 0.08P[/tex]

[tex]638 - A = 0.21*(4000 - P)[/tex]

So, on the second equation:

[tex]A = 638 - 0.21*(4000 - P)[/tex]

Replacing on the first:

[tex]A = 0.08P[/tex]

[tex]638 - 0.21*(4000 - P) = 0.08P[/tex]

[tex]638 - 840 + 0.21P = 0.08P[/tex]

[tex]0.21P - 0.08P = 840 - 638[/tex]

[tex]0.13P = 202[/tex]

[tex]P = \frac{202}{0.13}[/tex]

[tex]P = 1553.8[/tex]

Rounding up to the nearest integer

P = 1554.

So on A, the 8% interest, you invest $1554.

On B, the 21% interest, you invest 4000 - 1554 = $2446.

Solve the system of equations using subtraction.
{y=x+4
{y=2x+4

Answers

Answer:

x=0, y=4

(0,4)

Step-by-step explanation:

y=x+4

y=2x+4

The directions say substitution not subtraction

Set the two equations equal to each other

x+4 = 2x+4

Subtract x from each side

x+4-x = 2x+4-x

4 = x+4

Subtract 4 from each side

4-4 =x+4-4

0 =x

Now find y

y = x+4

y = 0+4

y = 4

Answer:

(0, 4)

Step-by-step explanation:

Our two equations are:

y = x + 4

y = 2x + 4

We need to use substitution, so let's substitute x + 4 in for y in the second equation:

y = 2x + 4

x + 4 = 2x + 4

x = 0

Plug this value back into one of the equations to solve for y:

y = x + 4

y = 0 + 4 = 4

Thus, the answer is (0, 4).

two solutions of salt water contain 0.1% and 0.22% salt respectively. A lab technician wants to make 1 liter of solution which contains 0.19% salt. How much of each solution should she use?

Answers

Answer:

0.25 L at 0.1% and 0.75 L at 0.22%

Step-by-step explanation:

We have to:

         percent                                 quantity

  Salt solution # 1 0.1                            x L

 Salt solution # 2 0.22                     (1 - x) L

    Mixture 0.19%                                    1

We are left with the following equation:

0.1 * x + 0.22 * (1-x) = 0.19 * 1

solving:

0.1 * x + 0.22-0.22 * x = 0.19

0.1 * x- 0.22 * x = 0.19 - 0.22

-0.12 * x = -0.03

x = -0.03 / -0.12

x = 0.25

Which means

Salt solution # 1 0.1% 0.25 L should be used and for salt solution # 2 0.22% 0-75 (1 - 0.25) L

Ruth has 12 feet of ribbon.
She uses 7 feet of it for a craft project and gives 28 inches of it to her sister.
How many inches of ribbon does she have left?
Enter your answer in the box.

Answers

Answer:

See I don't know the answer but I did another one like this if it doesn't help you can report it no problem

Step-by-step explanation:

There are 2 different ways you can solve this problem and you'll get the same answer.

To help you visualize what you have to do, it might be easiest to translate your problem to a unit that easier to use.

Since you only have a ribbon 5 feet long, but you must cut it into 6 pieces, you know it won't even be 1 foot long.

One way to solve the problem would be to translate your 5-foot ribbon into a ribbon divided into inches.

1 foot = 12 inches

To find out how many inches long your ribbon is, you'll need to multiply the number of feet by 12.

Once you know that, then you can more easily divide it by 6. This will tell you how many inches each ribbon is.

Careful! the answer is to be put into feet so once you know how many inches long the ribbon is, you must then divide by 12 to get the correct answer in feet. Don't forget to round to the nearest tenth.

Another way to solve the problem is to simply divide the 5 feet by the number 6 and then round your number to the nearest tenth. It may be harder to visualize the answer this way, but you will get the same answer as if you translated your ribbon into inches and then divided by 12.

Good luck! I hope this helps!

A powder diet is tested on 49 people, and a liquid diet is tested on 36 different people. Of interest is whether the liquid diet yields a higher mean weight loss than the powder diet. The powder diet group had a mean weight loss of 42 pounds with a standard deviation of 12 pounds. The liquid diet group had a mean weight loss of 45 pounds with a standard deviation of 14 pounds.

Answers

Answer:

There is not enough evidence to support the claim that the liquid diet yields a higher mean weight loss than the powder diet (P-value = 0.15).

Step-by-step explanation:

This is a hypothesis test for the difference between populations means.

The claim is that the liquid diet yields a higher mean weight loss than the powder diet.

Then, the null and alternative hypothesis are:

[tex]H_0: \mu_1-\mu_2=0\\\\H_a:\mu_1-\mu_2< 0[/tex]

The significance level is 0.05.

The sample 1 (powder diet group), of size n1=49 has a mean of 42 and a standard deviation of 12.

The sample 2 (liquid diet group), of size n2=36 has a mean of 45 and a standard deviation of 14.

The difference between sample means is Md=-3.

[tex]M_d=M_1-M_2=42-45=-3[/tex]

The estimated standard error of the difference between means is computed using the formula:

[tex]s_{M_d}=\sqrt{\dfrac{\sigma_1^2}{n_1}+\dfrac{\sigma_2^2}{n_2}}=\sqrt{\dfrac{12^2}{49}+\dfrac{14^2}{36}}\\\\\\s_{M_d}=\sqrt{2.939+5.444}=\sqrt{8.383}=2.895[/tex]

Then, we can calculate the t-statistic as:

[tex]t=\dfrac{M_d-(\mu_1-\mu_2)}{s_{M_d}}=\dfrac{-3-0}{2.895}=\dfrac{-3}{2.895}=-1.04[/tex]

The degrees of freedom for this test are:

[tex]df=n_1+n_2-1=49+36-2=83[/tex]

This test is a left-tailed test, with 83 degrees of freedom and t=-1.04, so the P-value for this test is calculated as (using a t-table):

[tex]\text{P-value}=P(t<-1.04)=0.15[/tex]

As the P-value (0.15) is greater than the significance level (0.05), the effect is not significant.

The null hypothesis failed to be rejected.

There is not enough evidence to support the claim that the liquid diet yields a higher mean weight loss than the powder diet.

If the length of SR is 4 m and the length of ST is 8 m, what is the length of PQ in meters?



Answers

Answer:

length PQ = 8.9 m  

Step-by-step explanation:

The picture below completes the question you  asked. From the picture above RSTU is a rectangle . The two shaded square has a length of sides 8 m and 4 m respectively. The legs of the triangle is the sides of the 2 squares. Therefore, the triangle is a right angle triangle. The adjacent side is 4 m while the opposite side is 8 m.

Using Pythagoras theorem the hypotenuse of the triangle can be calculated below.

Pythagoras theorem

c² = a² + b² Therefore,

c² = 4² + 8²

c² = 16 + 64

c² = 80

square root both sides

c = √80

c = 8.94427191

c ≈ 8.9 m

Answers

Answer:0.0256

Step-by-step explanation:

Given

Probability of being a male is [tex]P_1=0.466[/tex]

Probability of being born in america is [tex]P_2=0.153846[/tex]

Probabilty of being born in an urban location is [tex]P_3=0.3571428[/tex]

So probabilty of that a baby will be born a male,in North america, in an urban area=P

Since, [tex]P_1, P_2, P_3[/tex] are independent of each other therefore

[tex]P=P_1\times P_2\times P_3[/tex]

[tex]P=(0.466)\times (0.153846)\times (0.3571428)[/tex]

[tex]P=0.02560[/tex]

Which expression represents the length of the hypotenuse, c, of the triangle below?

C

b

a? - 62

va2 +62

a? + b2

a2

62

Answers

Answer:

Length of hypotenuse = √( a² + b²)

Step-by-step explanation:

The question is incomplete and unclear. From the question, it is clear we are to determine the hypotenuse of the triangle. Hence the triangle is a right angled triangle.

Find attached the diagram used in solving the question.

From the diagram,

a = opposite

b = adjacent

c = hypotenuse

To find the hypotenuse of a right angled triangle, we apply Pythagoras theorem.

Using Pythagoras theorem

Hypotenuse² = opposite ² + adjacent²

Insert the values of each, we have:

c² = a² + b²

Then we find the Square root both sides

c = √( a² + b²)

So we can insert the values of a and b if we are given.

For instance, if b = 6

c = √( a² + 6²)

Using the diagram,

Hypotenuse: c = √( a² + b²)
