Answer:
m∠R = 72°; m∠U = 65°
Step-by-step explanation:
We know that in any quadrilateral, the total sum of the angles will always add up to 360°.
For number 26, we can use this equation to find x and m∠R:[tex]90+98+12x+4+10x-8=360\\(90+98+4-8)+(12x+10x)=360\\184+22x=360\\22x=176\\x=8[/tex]
m∠R = 10 (8) - 8 = 80 - 8 = 72°
For number 28, we can use this equation to find x and m∠U
[tex]96+88+11x+1+7x-5=360\\(96+88+1-5)+(11x+7x)=360\\180+18x=360\\18x=180\\x=10[/tex]
m∠U = 7 (10) - 5 = 70 - 5 = 65°
Ryder found the volume of the figure below by using the steps shown. A rectangular prism with a length of 40 millimeters, width of 30 millimeters, and height of 5 millimeters. A rectangular pyramid with a base of 30 millimeters by 40 millimeters and a height of 95 millimeters. Total Volume = B h + one-half B h Equals 5 (40) (3) + one-half (40) (30) (95) Equals 6,000 + 57,000 Equals 63,000 cubic millimeters What mistake, if any, did Ryder make? Ryder determined the volume correctly. Ryder used the wrong formula for the total volume. Ryder used the wrong height for the pyramid. Ryder did not apply the order of operations correctly.

There are 7 balls in the bag: 3 blue, 2 red and 2 white. What is the probability that one would pick two balls of the same colour?
Answer:
5/21.
Step-by-step explanation:
Total number of balls = 7.
Prob(Blue on first pick) = 3/7
Prob(Blue on second pick) = 2/6 = 1/3
So Prob( 2 Blue's) = 3/7 * 1/3 = 3/21 = 1/7.
Prob(Red on first pick) = 2/7
Prob(Red on second pick) = 1/6
So Prob( 2 Red's) = 2/7 * 1/6 = 1/21.
Now the Probability of getting 2 white balls is the same as for the red balls
= 1/21.
Finally, the probability of 2 balls of the same colour
= 1/7 + 1/21 + 1/21
= 3/21 + 1/21 + 1/21
= 5/21.
the probability of picking two balls of the same color is 5/21.
To calculate the probability of picking two balls of the same color, we need to consider all the possible combinations of drawing two balls from the bag and then determine how many of those combinations result in both balls being the same color.
Total number of balls in the bag = 7
1. Probability of picking two blue balls:
Number of blue balls = 3
Probability of picking the first blue ball = 3/7
Probability of picking the second blue ball (after one blue ball has been picked) = 2/6 (since there are 2 blue balls left after one has been picked)
Total probability of picking two blue balls = (3/7) * (2/6) = 6/42 = 1/7
2. Probability of picking two red balls:
Number of red balls = 2
Probability of picking the first red ball = 2/7
Probability of picking the second red ball (after one red ball has been picked) = 1/6 (since there is 1 red ball left after one has been picked)
Total probability of picking two red balls = (2/7) * (1/6) = 2/42 = 1/21
3. Probability of picking two white balls:
Number of white balls = 2
Probability of picking the first white ball = 2/7
Probability of picking the second white ball (after one white ball has been picked) = 1/6 (since there is 1 white ball left after one has been picked)
Total probability of picking two white balls = (2/7) * (1/6) = 2/42 = 1/21
Now, we add up the probabilities of picking two balls of the same color:
Total probability = Probability of two blue balls + Probability of two red balls + Probability of two white balls
Total probability = 1/7 + 1/21 + 1/21
Total probability = (3 + 1 + 1)/21
Total probability = 5/21
Therefore, the probability of picking two balls of the same color is 5/21.

Suppose the lengths of 3-year-old cats are normally distributed with a mean of 30 inches and a
standard deviation of 2.92 inches. Find each of the following:
1. The percent of cats between 24.16 and 35.84
2. The percent of cats who are longer than 35.84
3. The percent of cats shorter than 24.16 inches
1. The percent of cats between 24.16 and 35.84 is 95%
2. The percent of cats who are longer than 35.84 is 2.28 %
3. The percent of cats shorter than 24.16 inches is 2.28%
What is the empirical rule formula in statistics?The empirical rule - formula
95% of data falls within 2 standard deviations from the mean - between μ – 2σ and μ + 2σ .
Mean, u = 30 inches
Standard Deviation, s = 2.92 inches
Formula for z-score = (x-u)/s
1. We have to find the percent of cats between 24.16 and 35.84 inches.
24.16, z-score = -2
35.84, z-score = 2
According to the empirical rule,
95% of the data values are within 2 standard deviations of the mean.
So, 95% of the cats are between 24.16 and 35.84 inches.
2. Here, x = 35.84
z=(35.84-30)/2.92
z= 2
According to the Empirical Rule,
95% of the values lie within 2 standard deviations of the mean.
So, the percent of cats who are longer than 35.84
100 - 97.72 = 2.28%
3. Now, x = 36.22
Using the formula mentioned above, we get:
z= 24.16-30/2.92
z=-2
According to empirical rule,
68% of the values lie within 1 standard deviation of the mean.
i.e., remaining 32% are outside the 1 standard deviation and half of the values i.e. 16% are below 1 standard deviation.

The measure of an angle is 5°. What is the measure of its supplementary angle?
Answer:
175 degrees.
Step-by-step explanation:
Supplementary angles add up to 180 degrees
Therefore the answer is:
180 - 5
= 175 degrees.
Hi Student!
The first step to almost any problem is that we must concentrate the important information that is given to us in the problem. This problem gives us information including that the measure of an angle is 5 degrees and that this angle is part of a supplementary pair. Let's define what a supplementary pair or angles are.
Supplementary Angles: These are two angles that are right next to each other on a straight line. These angles combine to a total of 180 degrees.Complementary Angles: These are two angles that are right next to each other but this time they are on a right angle. These angles combine to a total of 90 degrees.Now that we have our definitions and important information, we can move onto the next part which is actually finding the other angle. This step is simple now that we know that supplementary angles add up to 180. We can just create an equation that will help us determine our solution.
[tex]angle_1\ +\ angle_2 = 180\ degrees[/tex]
[tex]5\ degrees\ +\ angle_2 = 180\ degrees[/tex]
[tex]5\ degrees-5\ degrees\ +\ angle_2 = 180\ degrees-5\ degrees[/tex]
[tex]angle_2 = 175\ degrees[/tex]
Therefore, our final solution to the supplementary angle of 5 degrees is 175 degrees which can be found by subtracting the given angle from 180.
At the beach, Cody saw 4 times as many
seagulls as pelicans. If there were a total of 30
birds, how many birds were pelicans?
Answer:
6 pelicans
Step-by-step explanation:
Let x = number of pelicans
Cody saw 4 times as many seagulls as pelicans:
⇒ number of seagulls = 4x
Total of 30 birds:
⇒ seagulls + pelicans = 30
⇒ 4x + x = 30
⇒ 5x = 30
⇒ x = 6
Therefore, there were 6 pelicans (and 24 seagulls).

[tex]\large\boxed{\sf x = \frac{7x-1}{8} }[/tex]
Group the Variable's:
2 x - 5 + 7 y - 3 = 9 x - 1 - y -8
2x -9x + 7y +y = -1 -8 +5 + 3
-7x + 8y = -1
From this find x and y
For X
-7x + 8y = -1
-7x = -1 -8y
7x = 8y + 1
x = (8y +1)/7
For Y
-7x + 8y = -1
8y = -1 +7x
y = (7x -1)/8
