Answer: ∠1 and ∠5∠2 and ∠6∠3 and ∠7∠4 and ∠8

Step-by-step explanation:

∠3 and ∠6∠4 and ∠5

The missing angles  m∠ 3 is 97°, m∠10 is 97°,m∠9 is 83 degrees, m∠5 is 97 degrees, m∠7 is 83 degrees and m∠16 is 97 degrees.

An angle is formed when two straight lines or rays meet at a common endpoint.

The given angles m∠ 2 = 97° and m∠ 6 = 83°.

We have to find the other angles.

m∠ 3 is equal to  m∠ 2

m∠ 3 is 97°

m∠10 is corresponding angle to m∠ 2

m∠10 is 97°

Now m∠9 + m∠10 = 180
m∠9 + 97 =180

m∠9 = 180-97

m∠9 is 83 degrees.

As m∠6 is 83 degrees.

m∠6+m∠5 = 180

83+m∠5=180

m∠5 is 97 degrees.

m∠7 is 83 degrees.

m∠16 is 97 degrees.

Hence, the missing angles  m∠ 3 is 97°, m∠10 is 97°,m∠9 is 83 degrees, m∠5 is 97 degrees, m∠7 is 83 degrees and m∠16 is 97 degrees.

Step-by-step explanation:

Answer:

x is 90 z is 60 and y is 30

Step-by-step explanation:

Answer:

Step-by-step explanation:

The mean, \(\bar{x}\), is 90 and the standard deviation, \(\sigma\), is 12.  We are looking for the probability that the variable X will fall between 57 and 105. We use the z-score table for this, AFTER we find the z scores. The formula to find the z-scores for us is:

\(P(\frac{57-\bar{x}}{\sigma}\leq z\leq \frac{105-\bar{x}}{\sigma})\) and we fill in accordingly:

\(P(\frac{57-90}{12}\leq z\leq \frac{105-90}{12})\) which simplifies to

\(P(-2.75\leq z\leq 1.25)\) and we will break them up into 2 different sets as follows:

P(-2.75 ≤ z ≤ 0) + P(0 ≤ z ≤ 1.25)

and based on the fact that z scores are given from 0 on up, we are going to convert the first one by using the logic that if z is greater than -2.75 but less than 0, by symmetry, z is greater than 0 but less than 2.75:

P(0 ≤ z ≤ 2.75) + P(0 ≤ z ≤ 1.25) and we go to the z-score table.

Locate 2.7 down along the left side and move over til you're under the .05; that gives us the z-score for 2.75 which is .4970. Do the same for 1.25 to get a z-score of .3944. Add them together to get a final z-score that covers the range of values for X:

.4970 + .3944 = 0.8914

Answer:

Now Myra has 60 lines of code, no grid picture attached.

Step-by-step explanation:

If Myra removed 20% of the lines and she started with 75 lines of code, then she is removing 1/5 of those lines of code.

75 divided by 5 is 15, and 75 - 15 = 60

Now Myra would have 60 lines of code. It's unclear what grid you are talking about though - could you attach a picture of the grid you need to shade in?

We need to find the perimeter of the shape given by the coordinates. Let's start by drawing a Cartesian coordinate system and identifying the points. This will give us information about the geometric shape.

A Cartesian coordinate system is given in the photos below and the indicated points [(2,3), (2,8), (6,3) and (6,8)] are marked.

We can see that this shape is a rectangle. A rectangle is home to two sides of different lengths, long and short. To find the perimeter of a rectangle, we add the length of the long side and the length of the short side and multiply the result by \(2\). (Because a rectangle must have \(2\) long sides and \(2\) short sides).

The rectangle in the figure has a long side length of \(5\) feet and a short side length of \(4\) feet.

Perimeter: \(2(L+S) = 2(5+4)=18ft.\)

Answer

linear

nonproportional

Step-by-step explanation:

Since for each equal change in time (1 week), there is an equal change in weight (5 lb), the situation is linear.

At time zero, the first week, the weight was not zero. It was 60 lb, so it is not proportional.

Answer:

linear

nonproportional

Answer:

To simplify the expression -3x(-8x+52+5+3), we can distribute the -3x to each term inside the parentheses:

-3x(-8x+52+5+3) = 24x² - 156x - 15x - 9x

Simplifying further by combining like terms, we get:

-3x(-8x+52+5+3) = 24x² - 180x - 9x

Therefore, the simplified expression is 24x² - 189x. None of the options given match this answer. Therefore, there seems to be an error in the original question.

Answer:

y = -3x +5

Step-by-step explanation:

Parallel means that both slopes are the same.

This gives us y = -3x + C so far.

To find the y-intercept, we need to get x to 0.

Since we know the point (-1, 8), we can plug the number in into our equation

y = -3x + C.

8 = -3(-1) + C

8 = 3 + C

8 - 3 = C

5 = C or C = 5.

Now plug in C into our unsolved equation to get y = -3x +5.

The integer that represents the given situation is a positive 31.

The temperature being 31 degrees above zero means that it is warmer than the freezing point of water. In this context, "above zero" refers to the Celsius or Fahrenheit scale, where zero represents the freezing point of water. Therefore, a temperature of 31 degrees above zero is a positive value indicating a warm temperature.

In this case, it can be assumed that the temperature is being measured in Celsius since 31 degrees above zero on the Fahrenheit scale would correspond to a very high temperature of approximately 87 degrees Fahrenheit. Overall, the integer that represents this situation is positive 31, which signifies a warm temperature above the freezing point.

$ 555,911.5

Explicación paso a paso:

Dado

Principal = $ 545,680

Interés = 2,25%

Tiempo = 10 meses = 10/12 años

Debemos buscar la cantidad después de 10 meses.

Monto = Principal + Intereses

Interés = PRT / 100

Interés = 545,680 * 2,25 * 10/1200

Intereses = 12,277,800 / 1200

Interés = 10.231,5

Cantidad = 545,680 + 10,231.5

Cantidad = 555,911.5

The simplified version of (sec a - cosec a) / (sec a + cosec a)  is cosec 2a(cosec 2a - 2) / (sec²a - cosec²a).

The study of correlations between triangles' side lengths and angles is known as trigonometry. The field was created in the Hellenistic era in the third century BC as a result of the use of geometry in astronomical research.

Given:

(sec a - cosec a) / (sec a + cosec a)

Multiply the numerator and denominator by (sec a - cosec a)

(sec a - cosec a) / (sec a + cosec a)  × (sec a - cosec a)

(sec²a + cosec²a -2sec a cosec a) / (sec²a - cosec²a)

As we know,

\(sec^2a + cosec^2a = sec^2a \ cosec^2a\)

sec² a cosec² a - 2sec a cosec a /  (sec²a - cosec²a)

sec a cosec a (sec a cosec a - 2) / (sec²a - cosec²a)

cosec 2a(cosec 2a - 2) / (sec²a - cosec²a)

Answer:

well your answer should be "F"

Step-by-step explanation:

we have

Y<-2x+10  -----> inequality A

The solution of the inequality A is the shaded area below the dashed line

Y = -2x+10

The y-intercept of the dashed line is (0,10)

The x-intercept of the dashed line is (5,0)

Y<1/2x-2 ----> inequality B  

The solution of the inequality B is the shaded area below the dashed line

Y= 1/2x-2

The y-intercept of the dashed line is (0,-2)

The x-intercept of the dashed line is (4,0)

The solution of the system of inequalities is the shaded area between the two dashed lines

Remember that

If a ordered pair is a solution of the system of inequalities, then the ordered pair must lie on the shaded area of the solution

therefore

The solution are the points

Its A because you find the slope, -1/3 which is followed by x.  The x intercept is 1 so you do plus one.  Because the line is solid and negative, it makes it a less-than equal to sign.  Hope this helps at all!

Step-by-step explanation:

To determine whether the triangle with vertices P(2, -1, -1), Q(3, 2, -3), and R(7, 0, -4) is right-angled, we can use vectors.

First, we calculate the vectors formed by the sides of the triangle:

Vector PQ = Q - P = (3, 2, -3) - (2, -1, -1) = (1, 3, -2)
Vector PR = R - P = (7, 0, -4) - (2, -1, -1) = (5, 1, -3)

Next, we take the dot product of these two vectors:

PQ · PR = (1, 3, -2) · (5, 1, -3) = 1 * 5 + 3 * 1 + (-2) * (-3) = 5 + 3 + 6 = 14

If the dot product is zero, then the two vectors are perpendicular, indicating that the triangle is right-angled.

In this case, since PQ · PR = 14 ≠ 0, the triangle with vertices P, Q, and R is not right-angled.
