What is 2+2? I cant figure it out I took 4 hours

We have been given that in ΔHIJ, the measure of ∠J=90°, the measure of ∠I=29°, and JH = 88 feet. We are asked to find the length of IJ to the nearest tenth of a foot.

First of all, we will draw a right triangle using our given information as shown in the attachment.  

We can see that in triangle HIJ, the side IJ is adjacent side to angle I and JH is opposite side to angle I.

We know that tangent relates opposite side of right triangle to adjacent side.

[tex]\text{tan}=\frac{\text{Opposite}}{\text{Adjacent}}[/tex]

[tex]\text{tan}(29^{\circ})=\frac{88}{IJ}[/tex]

[tex]IJ=\frac{88}{\text{tan}(29^{\circ})}[/tex]

[tex]IJ=\frac{88}{0.554309051453}[/tex]

[tex]IJ=158.7562024638191237[/tex]

Upon rounding to nearest tenth, we will get:

[tex]IJ\approx 158.8[/tex]

Therefore, the length of the side IJ is approximately 258.8 units.

Answer:

it's 158.8

Step-by-step explanation:

Answer:

= $ 158.44

Step-by-step explanation:

$ 233 = 100%

100% - 32% = 68% which is the percentage that represents the new price

If 100% = $ 233

What about 68% = $?

= (68 x 233) ÷ 100

= 15844 ÷ 100

= $ 158.44

Answer:

B.

Step-by-step explanation:

Trust me.

I just did it.

The correct statement is:

In repeated sampling, the true proportion of county residents in favor of having more public parks in that county will fall in the interval (0.51, 0.57).

Option D is the correct answer.

A confidence interval is a range of values that is likely to contain the true value of an unknown parameter, such as a population means or proportion, based on a sample of data from that population.

It is a statistical measure of the degree of uncertainty or precision associated with a statistical estimate.

We have,

The 98% confidence interval for the proportion of residents in favor of having more public parks in the county is 0.54 ± 0.03.

This means that we are 98% confident that the true proportion of residents in favor of having more public parks in the county falls within the interval from 0.51 to 0.57.

Now,

The correct statement is:

In repeated sampling, the true proportion of county residents in favor of having more public parks in that county will fall in the interval (0.51, 0.57).

Option a is incorrect because we cannot determine whether the majority of residents are in favor of having more public parks based solely on the confidence interval.

Option b is incorrect because we cannot determine whether the estimate of 0.54 is within 0.03 of the true proportion of county residents in favor of having more public parks based solely on the confidence interval.

Option c is incorrect because it is a statement about the probability of the sample proportion falling within the interval in repeated sampling, which is not the same as the true proportion falling within the interval.

Option e is incorrect because it is a statement about the probability of the true proportion being equal to 0.54 in repeated sampling, which is not necessarily true based solely on the confidence interval.

Thus,

The correct statement is:

In repeated sampling, the true proportion of county residents in favor of having more public parks in that county will fall in the interval (0.51, 0.57).

Answer:

Area = 25.12 square units.

Perimeter = 20.56  units

Step-by-step explanation:

If you are looking for area, here goes:

Area of circle = π * r^2  

Area of semi-circle = S = (1/2) *π * r^2

S =  (1/2)*π*(4^2) = (1/2)π*16 = 8π square units = 25.12 square units

Or if you are looking for the perimeter:

Circumference C = 2*π*r

Half-circumference =  (1/2)C = (1/2)*2*π*r =  π*r = π*4

Perimeter of semi-circle =  4 + 4 + 4π = 8 + 4π

Answer:

A plain pizza is $10.50. A pepperoni pizza is $12.50.

Step-by-step explanation:

Solve a system of equations. Call x the price of plain pizzas and y the price of pepperoni pizzas. From the question we are told that for Jack:

[tex]58.50=2x+3y[/tex]

And for Jill:

[tex]67=4x+2y[/tex]

There are several ways to solve this. I'll used elimination. Multiply the first equation by 2:

[tex]117=4x+6y[/tex]

Now subtract the second equation from the first - this will get rid of the x, leaving only y, which can be solved for:

[tex](117-67)=(4x-4x)+(6y-2y)\\50=4y\\y=12.5[/tex]

Now sub the value for y into either of the original equations and solve for x. I'll use the first:

[tex]58.5=2x+3(12.5)\\58.5=2x+37.5\\21=2x\\x=10.5[/tex]

Answer:

One plain pizza would be $10.50 and one pepperoni pizza would be $12.50.

complete question:

The value of Q is given by the relation Q = 17m. If m is an integer greater than 15 and less than 23, then which of the following is the value of Q?

A. 255

B. 290

C. 306

D. 391

Answer:

C. 306

Step-by-step explanation:

The equation is Q = 17m. m is an integer and it is greater than 15 and less than 23 . This means m can only be 16, 17, 18, 19, 20, 21 and 22.

Insert any of the value of Q from the options in the equation Q = 17m and solve the equation. The answer of m must be between 16 to 22.

let us try

option A

Q = 17m

255/17 = m

m = 15 (not A since it not greater than 15)

option B

Q = 17m

290/17 = m

m = 17.0588235294

(not an integer)

option C

Q = 17m

306/17 = m

m = 18

(correct . it is an integer and greater than 15 and less than 22)

option D

Q = 17m

391/17 = m

m = 23

(not less than 23)

Answer:

96% probability that the test result is correct

Step-by-step explanation:

We have these following probabilities:

2.3% probability that a randomly selected light is defective.

If the light is defective, 94% probability that the test result is correct.

100-2.3 = 97.7% probability that a randomly selected light is not defective.

If the light is not defective, 96% probability that the test result is correct.

What is the probability that the test result is correct?

94% of 2.3% and 96% of 97.7%. So

p = 0.94*0.023 + 0.96*0.977 = 0.96

96% probability that the test result is correct

We have been given that [tex]\text{sin}(A)=\frac{12}{13}[/tex] and angle A is in quadrant 1. We are asked to find the exact value of [tex]\text{cot}(A)[/tex] in simplest radical form.

We know that sine relates opposite side of right triangle with hypotenuse.

[tex]\text{sin}=\frac{\text{Opposite}}{\text{Hypotenuse}}[/tex]

This means that opposite side is 12 units and hypotenuse is 13 units.

We know that cotangent relates adjacent side of right triangle with adjacent side.

[tex]\text{cot}=\frac{\text{Adjacent}}{\text{Opposite}}[/tex]

Now we will find adjacent side using Pythagoras theorem as:

[tex]\text{Adjacent}^2=\text{Hypotenuse}^2-\text{Oppoiste}^2[/tex]

[tex]\text{Adjacent}^2=13^2-12^2[/tex]

[tex]\text{Adjacent}^2=169-144[/tex]

[tex]\text{Adjacent}^2=25[/tex]

Let us take positive square root on both sides:

[tex]\sqrt{\text{Adjacent}^2}=\sqrt{25}[/tex]  

[tex]\text{Adjacent}=5[/tex]

Therefore, adjacent side of angle A is 5 units.

[tex]\text{cot}(A)=\frac{5}{12}[/tex]

Therefore, the exact value of cot A is [tex]\frac{5}{12}[/tex].

The exact value of cot(A), where sin(A) is 12/13 and angle A is in Quadrant 1, is 5/12 in simplest radical form with a rational denominator.

Step-by-step explanation:

Lightning is just a high-intensity amount of electricity. Picture zapping something with electricity: it doesn't get cold, it gets hot.

That's because when a current is passed through something, it has more energy, so the molecules start to vibrate faster and move around much faster than they were before, which causes friction and a buildup of heat.

Answer: Eliana should add 9 cups of fertilizer to the pot.

Step-by-step explanation:

Given , Eliana always adds 3 cups of fertilizer for every 8 cups of soil. .

As the quantity of fertilizer is proportional to the quantity of soil.

That means,

[tex]\dfrac{\text{Number of cups of fertilizer for 24 cups of soil}}{\text{24}}=\dfrac{\text{Number of cups of fertilizer for 8 cups of soil}}{8}\\\\\Rightarrow \dfrac{\text{Number of cups of fertilizer for 24 cups of soil}}{24}=\dfrac{3}{8}[/tex]

Multiply 24 on both sides , we get

[tex]\Rightarrow\ \text{Number of cups of fertilizer for 24 cups of soil}=\dfrac{3}{8}\times24=3\times3=9[/tex]

Hence, Eliana should add 9 cups of fertilizer to the pot.

Eliana should add 9 cups of fertilizer to the pot.

To determine how many cups of fertilizer Eliana should add to the pot, we can use the given ratio of 3 cups of fertilizer for every 8 cups of soil. Since Eliana filled the pot with 24 cups of soil, we can set up the following proportion:

3 cups of fertilizer / 8 cups of soil = x cups of fertilizer / 24 cups of soil

By cross-multiplying and solving for x, we find that Eliana should add 9 cups of fertilizer to the pot.

Step-by-step explanation:

Answer:

Using the formula a² + b² = c², we can plug in those two numbers, which I assume are the legs, to get our answer.

- Once we plug it in, we have to isolate the variable.

THEN

- We must square root (√) the final answer. Like so:

6.4² + 8.9² = c²

DO: The variable is already isolated, so we must do this a little differently. We'll square each number like it shows, and then add the two numbers together.

6.4² = 40.96

8.9² = 79.21

NOW: We can add them together.

40.96 + 79.21 = 120.17

LOOK: 120.17 = c²

We must now get rid of the 2, by square rooting both sides!

Step-by-step explanation:

Formula: multiply the value by 100

Final answer:

The statement that is true is D, which correctly states that 60 hectoliters are equal to 60000 liters, as 1 hectoliter equals 1000 liters.

Explanation:

The student has asked which statement is true regarding the comparison of different units of volume measurement. Only one of the statements given represents an accurate conversion:

Answer D

60 hectoliters (hL) equals 60000 liters (L). This is true because 1 hectoliter is equivalent to 1000 liters. Hence, if we have 60 hectoliters, we multiply 60 by 1000 to find the conversion in liters:

60 hL * 1000 L/hL = 60000 L

Therefore, statement D is correct.
