In parallelogram ABCD, mLA
4x + 20 and m2C = x + 26
Find the value of x.
Then find the measure of LA.
Answer:
Step-by-step explanation:
In a parallelogram, opposite angles are congruent.
∠A = ∠C
4x + 20 = x + 26
Step 1: To find the valu of 'x', first subtract 20 from both sides
4x = x + 26- 20
4x = x + 6
Step2: Now, subtract 'x' from both sides
4x -x = 6
3x = 6
Step:3: divide both sides by 3
x = 6/3
x = 2
∠A = 4*2 + 20
= 8 + 20
∠A = 28°

Rectangle PQRS is plotted on a coordinate plane. The coordinates of P are (– 1, 4) and the
coordinates of Q are (– 1, – 4). Each unit on the coordinate plane represents 1 centimeter, and
the area of Rectangle PQRS is 64 square centimeters. Find the coordinates of Points R and S
given these conditions:.aPoints R and S are to the left of Points P and Q.bPoints R and S are to the right of Points P and Q
Answer:
See belowStep-by-step explanation:
Given points P and Q have same x-coordinate but different y- coordinates.
The distance between P and Q is the difference of y- coordinates:
PQ = 4 - (-4) = 8 units = 8 cmThe area is 64 cm², it means the adjacent sides are
PS = QR = 64/8 = 8 cma)
If the points R and S are to the left, their coordinates are
S = (-1 - 8, 4- 0) = (- 9, 4)R = (-1 - 8, - 4 - 0) = (- 9, -4)b)
If the points R and S are to the right, their coordinates are
S = (-1 + 8, 4 + 0) = (7, 4)R = (-1 + 8, - 4 + 0) = (7, -4)Answer:
Points R and S are to the left of Points P and Q
R = (-9, 4)
S = (-9, -4)
Points R and S are to the right of Points P and Q
R = (7, 4)
S = (7, -4)
Step-by-step explanation:
Given coordinates:
P = (-1, 4)Q = (-1, -4)Points P and Q have the same x-value.
The vertical distance between these two points is:
[tex]\begin{aligned}\implies \sf y_P-y_Q & =\sf 4-(-4)\\ & =\sf 4+4\\ & =\sf 8\:units \\ & =\sf 8\:cm\end{aligned}[/tex]
Area of a rectangle = width × length
If the area of the rectangle PQRS is 64 cm² then:
[tex]\begin{aligned} \implies \sf 64 & = \sf width \times 8\\\implies \sf width & = \sf \dfrac{64}{8}\\\implies \sf width& = \sf 8 \: cm \end{aligned}[/tex]
This means that the y-values of points R and S will be the same as points P and Q, but the x-values will either be 8 less or 8 more.
Points R and S are to the left of Points P and Q
R = (-1 - 8, 4) = (-9, 4)
S = (-1 - 8, -4) = (-9, -4)
Points R and S are to the right of Points P and Q
R = (-1 + 8, 4) = (7, 4)
S = (-1 + 8, -4) = (7, -4)
charlie stands at point A while holding the control line attached to a model airplane. the plane travels 120 feet counterclockwise from point b to point c about how long is the control line
The counterclockwise direction of the airplane implies that it moves in the opposite direction
The control line could be 60 feet long
How to determine the length of the control line?The question is incomplete, as the figure that represents the control line and other parameters are not given.
However, a possible solution is as follows.
From the question, we understand that the airplane travels 120 feet counterclockwise.
The counterclockwise direction could represent that points B and C are on either sides of point A, such that:
AB = AC = 0.5* BC
So, we have
AB = 0.5* 120
AB = 60 feet
Hence, the control line could be 60 feet long

A simple random sample of earthquake depths yields the following:
n=600, x=5.82 km, and s=4.93 km
use a 0.01 significance level to test the claim of a seismologist that these earthquakes are from a population with a mean equal to 5.00km
The critical value becomes 2.584 for two tailed test since we have to reject the null hypothesis, t >2.584 or t < -2.584 test stat lie in the rejection region.
Test-Static tData;
mean = 5.82s = 4.93n = 600Let's calculate the t-value
[tex]t = \frac{x - \mu}{\frac{s}{\sqrt{n} } }[/tex]
Substitute the values into the equation and solve;
[tex]t = \frac{x - \mu}{\frac{s}{\sqrt{n} } } \\t = \frac{5.82 - 5}{\frac{4.93}{\sqrt{600} }} \\t = \frac{0.82}{0.201} \\t = 4.079[/tex]
The t-value is 4.079.
The allowed significance value = 0.01
The degree of freedom is n -1, which becomes 600 - 1 = 599.
The critical value becomes 2.584 for two tailed test since we have to reject the null hypothesis, t >2.584 or t < -2.584 test stat lie in the rejection region, we have to reject the null hypothesis or claim incorrect.

You can multiply 5x2 which easily equals 10. 6x6 equals 36 and you cannot multiply anything other than one and itself for 7, 13, 23, or 67. for part B, you can multiply 4x 11 to equal 44 and you can multiply 9x5 to equal 45 so it would be composite
44 and 45 are composite numbers.

For the following pairs, indicate which do not comply with the rules for setting up hypotheses, and explain why. (Select all that apply.)

This pair complies.This pair does not comply because ? is not a population characteristic.This pair does not comply because both hypotheses use an equal sign.This pair does not comply because the two hypotheses use different numbers.
(b) H0: p = 0.5, Ha: p > 0.6
This pair complies.This pair does not comply because p is not a population characteristic.This pair does not comply because both hypotheses use an equal sign.This pair does not comply because the two hypotheses use different numbers.

It can be inferred that H0: ? = 15, Ha: ? = 15 doesn't comply because both hypothesis use an equal sign.
How to illustrate the hypothesis?From the information, H0: p = 0.5, Ha: p > 0.6 doesn't comply because the two hypothesis use different numbers.
Furthermore, H0: ? = 121, Ha: ? < 121 shows that the pair complies. Also, H0: ? = 123, Ha: ? = 125 doesn't comply as they use the equal sign and different numbers.

Write the steps you will use to solve the equation and explain each step.
Answer:

Step-by-step explanation:
The first thing you should start with is distributing the 6 inside the parentheses, which would give us (12x - 66) + 15 = 21. Now we can add like terms on this side of the equation to get: 12x -51 = 21. Add the 51 to the right side to get 12x = 72, then divide both sides by 12 to get x = 72/12 or 6.
