Answer:

-1/4x

Step-by-step explanation:

Using the tangent ratio, the size of angle XYZ, to 1 decimal point is: 72.9°

The tangent ratio is given as, tan ∅ = opposite side/adjacent side of a right triangle.

Thus:

Thus:

tan (m∠XYZ) = 13/4

m∠XYZ = tan^-1(13/4)

m∠XYZ = 72.9°

Data;

To calculate the price before the festive season, we simply need to subtract 15% from $575.

[tex]\frac{15}{100} = \frac{x}{575} \\x = 86.25[/tex]

The increase in the ticket is $86.25., Let's calculate the price before the festive season.

I don't know what the steps are

Answer:

Step-by-step explanation:

To find equivalent fractions, we multiply the numerator and the denominator by the same number, so we need to multiply the denominator of 7 by a number that will give us 21. Since 3 multiplied by 7 gives us 21, we can find an equivalent fraction by multiplying both the numerator and denominator by 3.Oct 4, 2021

Problem 8

Answer: angle LSO and angle MSN

--------------

Explanation:

Vertical angles form when we intersect two line segments, lines, or rays. Vertical angles are opposite one another and they are always congruent.

=============================================

Problem 9

Answer: angle LMS and angle SMN

--------------

Explanation:

Adjacent angles share a common line, line segment, or ray. Think of two adjacent rooms sharing a common wall between them. In the case of the answer above, the two angles share the common segment SM (note how S and M are part of LMS and SMN)

When it comes to naming angles, the middle letter is always the vertex of the angle. This is the hinge so to speak. Or you could picture a pair of scissors. For angle LMS, the arms LM and SM are the two blades of the scissors while point M is where the blades meet.

=============================================

Problem 10

Answer: angle LSM and angle MSN

--------------

Explanation:

Same idea as problem 9. Now we're making S the middle letter. Something like angle LSM is the same as angle MSL.

In this case, the two adjacent angles form a straight line. We consider these two angles a linear pair.

=============================================

Problem 11

Answer: angle LSO and angle OSN

--------------

Explanation:

The term linear pair was discussed back in problem 10. So you could list those two angles again, or you could go with another pair as shown above. All that matters is that they are adjacent angles and they are supplementary angles (they add to 180 degrees). There are many possible answers.

Something like the angle pair angle LOS and angle NOS are adjacent angles, but they aren't supplementary. So we don't meet the condition of a linear pair here.

Step-by-step explanation:

Answer:

yes i believe so

Step-by-step explanation:

Using the t-distribution, as we have the standard deviation for the sample, it is found that it cannot be concluded that the diet has a long-term effect.

At the null hypotheses, it is tested if there is no difference in the weights, that is:

[tex]H_0: \mu_A - \mu_B = 0[/tex]

At the alternative hypotheses, it is tested if the weights decrease, that is:

[tex]H_1: \mu_A - \mu_B < 0[/tex]

Using a calculator, for each sample, we have that:

[tex]\mu_B = 210.8, s_B = 33.85, sE_B = \frac{33.85}{\sqrt{15}} = 8.74[/tex]

[tex]\mu_A = 207.2, s_A = 33.47, sE_A = \frac{33.47}{\sqrt{15}} = 8.64[/tex]

Hence, for the distribution of differences, we have that:

[tex]\overline{x} = \mu_A - \mu_B = 207.2 - 210.8 = -3.6[/tex]

[tex]s = \sqrt{sE_B^2 + sE_A^2} = \sqrt{8.74^2 + 8.64^2} = 12.3[/tex]

It is given by:

[tex]t = \frac{\overline{x} - \mu}{s}[/tex]

In which [tex]\mu = 0[/tex] is the value tested at the null hypothesis.

Then:

[tex]t = \frac{\overline{x} - \mu}{s}[/tex]

[tex]t = \frac{-3.6 - 0}{12.3}[/tex]

[tex]t = -0.29[/tex]

Considering a left-tailed test, as we are testing if the mean is less than a value, with a standard significance level of 0.05 and 15 + 15 - 2 = 28 df, the critical value is of [tex]t^{\ast} = -1.7[/tex].

Since the test statistic is greater than the critical value for the left tailed test, it cannot be concluded that the diet has a long-term effect, as the null hypothesis is not rejected.

Answer:

2 1/6

Step-by-step explanation:

How we calculate this is make the two fractions denominators the same so we can make them both 6.

for the 3 we times it by 2 and 2 by 3.

so our 2 fractions are now 2 4/6 and 3/6 Now

so if we take away 3 of 4 we get 1 so 2 and 4/6 is now 2 and 1/6

Meaning the 2 1/6 is what she has left so if she gives that all to her brother he gets that and there's your answer.

Answer:

C

Step-by-step explanation:

we want to "isolate" h (height). that means "h" needs to be alone on one side of the equation, and all other factors need to be brought to the other side.

so, yes, we need to divide both sides by all factors of h : pi and r². only then will we have the isolated h on one side.

therefore, dividing both sides by pi is a good first step.

Step-by-step explanation:

you're welcome

Step-by-step explanation:

so you have to make an equation where you let x=the number, so it would be

x+(2/3)x+(1/4)x=5 3/4

you combine the like terms to get

(23/12)x = 5 3/4

multiply both sides by the reciprocal of 23/12 to isolate x, and you're left with

x=36/92, which simplifies to 9/23.

5/4

Step-by-step explanation:

If the equation is

slope = 5/4.

Answer:

5/4.

The x is a variable, not a multiplication sign.

Answer:

1. 84in³

2. 180cm³

3. 600ft³

4. 360cm³

5. 312cm³

6. 15.6kg

7. 1.95kg

Step-by-step explanation:

1: V = Bh = (7x3)x4 = 84in³

2: V = Bh = 1/2(8x5) x 9

               = 20 x 9

               = 180cm³

3: V = Bh = 1/2(b1+b2) h    x     5

               = 1/2(20+10) 8    x     5

               = 15 x 8 x 5

               = 15 x 40

               = 600ft³

4: V = Bh = 1/2 (4x9) x 20

               = 18 x 20

               = 360cm³

5: Total volume = Volume of rectangular prism + Volume of triangular block

                          = (8.5 x 4 x 9) + 1/2(1.5 x 2) x 4

                          = 306 + 6

                          = 312cm³

6: divide 312cm³ by 20kg/cm³ to get the approx. mass:

              312/20 = 15.6kg

7: first find the volume of the friends Display:

                          = (4.25 x 2 x 4.5) + 1/2(0.75 x 1) x 2

                          = 38.25 + 0.75

                          = 39cm³

Now divide by 20 to find the approx. weight of the friends display:

39/20 = 1.95kg

Have a nice day! :)
