HURRYYYY PLEASEEEEfind The Value Of X.

Answers

Answer 1
x = 31

180 = 3x + 25 + 2x
180 = 5x + 25
-25. -25
155 = 5x
x = 31
Answer 2

Answer:

x=31

Step-by-step explanation:

Hello there!

the shown angles are supplementary meaning that the sum of the two is 180

so we create an equation

180=3x+25+2x

step 1 combine like terms

3x+2x

now we have

180=25+5x

step 2 subtract 25 from each side

180-25=155

now we have

155=5x

step 3 divide each side by 5

155/5=31

5x/5=x

we're left with x=31

What would x equal( rounded to the nearest tenth)

Answers

You are given the opposite: 16 km
You need to find x (adjacent)
The angle measure: 28 degrees
With opposite and adjacent, use tangent
Tan(28) = 0.5317094317
Tan(28) = 16/x
x = 16/0.5317094317
x = 30.0916
Round to nearest tenth
Solution: x = 30.1 km
8.5 i think cause i used tan but i haven’t done this in a while

One interior angle of a triangle is 60°. The other angle measures are x° and yº. Which of the following could be the values of
x and y? Select all that apply. X = 60, y = 60
X = 100, y = 20
X = 40, y = 80. x=50, y = 90
X = 45, y = 45

Answers

Answer:

x=60, y= 60

x=100, y= 20

x=40, y=80

Step-by-step explanation:

Triangles add up to 180 degrees. The ones above added to 60 equal 180.

60+60+60=180

100+20+60=180

40+80+60=180

Mrs.Davis deposits $8,000 into each of 2 savings accounts account 1 earns 6.5% simple interest account 2 earns earns 3% simple interest what’s the difference between the amounts of interest in account 1 and account 2 after 6 years?

Answers

Answer:

$1680

Step-by-step explanation:

The equation for simple interest is I = PRT, where I = interest earned, P = principal/amount invested, R = rate as a decimal, and T = time in years.

Account 1:

I = (8000)(0.065)(6)

I = $3,120

Account 2:

I = (8000)(0.03)(6)

I = $1,440

$3120 - $1440 = $1680

Some Girl Guides are raising money for their jamboree. Their goal is to raise $1000, They already have $232 from the bake sales. To raise the remainder, they are planning a walk-a-thon. if each person walking raises $24, how many walkers will the Girl Guides need to reach their goal?

Answers

I believe they need 32 walkers.
[correct me if I’m wrong]
why: if their goal is $1000 and they already have $232 you can subtract $232 from $1000 which would leave you with the rest of the money they need: $768. By dividing $768 by $24 (the amount of money they will raise for each person) you’ll end up with 32, being the number of walkers you’ll need because 32x24= $768, the remainder they need.

63 + 4.5 = 67.5

Answer:

10.3

Step-by-step explanation:

The question is asking to find the length of the hypotenuse of the triangle. This requires us to use the Pythagorean theorem. The legs measure 9 and 5, so we use these to solve for c.

[tex]9^{2} + 5^{2} =c^{2} \\81 + 25 = c^{2} \\106 = c^{2} \\[/tex]                            

We find the square root of both sides to find the value of c.

10.295 ≈ c

Rounded to the nearest tenth, c ≈ 10.3. The answer is 10.3

Step-by-step explanation:

You need to get rid of the fraction first and to do that you muliply the whole equation by 5 so that your new equation reads 4x+25=45. Then you subtract 25 from both sides so you have 4x=20. Divide both sides by 4 so x=5.

One leg of a right triangle is 3 cm and the hypotenuse is 5 cm. Joni found the length of the other leg by evaluating √32 + 52. What error did she make? How would you help her correct her error so she is less likely to make the same error in the future?

Answers

Answer: See explanation

Step-by-step explanation:

We should note that the hypothenuse is the longest side in a triangle. Therefore, the length of the other side will be represented by x. This is then solved below:

x² + 3² = 5²

x² + 9 = 25

x² = 25 - 9

x² = 16

x = ✓16

x = 4cm

The other leg is 4cm

Joni shouldn't have added the hypothenuse to the other leg but rather subtracted the square of the other leg from the square of the hypothenuse and then find the square root.

The results of a series of surveys revealed a population with a mean of 4.73 and a standard deviation of 0.865. If each survey has a sample size of 200, which value falls within the interval where 95% of the sample means occur? A. 4.88 B. 4.63 C. 4.91 D. 4.55

Answers

Answer:

4.63

Please give me brainliest, I really need it.

The value of 4.63 falls within the interval (4.66, 4.791) where 95% of the sample means occur option (B) is correct.

What is a confidence interval for population standard deviation?

It is defined as the sampling distribution following an approximately normal distribution for known standard deviation.

The formula for finding the confidence interval for population standard deviation as follows:

[tex]\rm s\sqrt{\dfrac{n-1}{\chi^2_{\alpha/2, \ n-1}}} < \sigma < s\sqrt{\dfrac{n-1}{\chi^2_{1-\alpha/2, \ n-1}}}[/tex]

Where s is the standard deviation.

n is the sample size.

[tex]\chi^2_{\alpha/2, \ n-1} and \chi^2_{1-\alpha/2, \ n-1}[/tex]  are the constant based on the Chi-Square distribution table.

α is the significance level.

σ is the confidence interval for population standard deviation.

Calculating the confidence interval for population standard deviation:

We know significance level = 1 - confidence level

 

It is given that:

Mean of the population x = 4.73

Standard deviation s = 0.865

Sample size n = 200

The interval where 95% of the sample means occur:

Lower limit = 4.73 - 0.865/√200

Lower limit = 4.66

Upper limit = 4.73 + 0.865/√200

Upper limit = 4.791

The interval = (4.66, 4.791)

Thus, the value of 4.63 falls within the interval (4.66, 4.791) where 95% of the sample means occur option (B) is correct.
