work out the value of angle x
Answer:
x = 45°
Step-by-step explanation:
the triangle has 2 congruent sides and is therefore isosceles with the base angles being congruent, both x
the sum of the 3 angles = 180° , then
x + x + 90° = 180° ( subtract 90° from both sides )
2x = 90° ( divide both sides by 2 )
x = 45°

Paxton multiplied 2/3 and 5/8 and came up with 30/24. What mistakes did Paxton make and what is the correct answer to Paxton's math problem?
Step-by-step explanation:
Paxton multiplied 2/3 times the 5 in the numerator. Then he multiplied the 3 and 8 in the denominator.
The correct way to solve this problem would be to multiply the numerators and then multiply the denominators. This would give you 10/24. You can then divide the numerator and deonminator by 2 and get 5/12.

Find the area of the figure above.
[?] square inches
Answer:
280 inches
Step-by-step explanation:
The area can be found by looking at each shape individually.
The area of the square can be found my multiplying the length by the width...
14*14 = 196 square inches
The area of the triangle can be found by multiplying the base by the height and dividing by 2...
A = b*h/2 (or some text books say half of the base times the height)
We knot the height of the triangle is 12 inches, and the base is implied as it shares a side with a square which has 4 equal sides of 14 inches. Therefore
A = (14*12)/2 = 84 square inches
We get the total area by combining the two segments...
Area (triangle) + Area (square) = Area (total)
84 + 196 = 280 square inches

I climb half the steps in a staircase. Next, I climb one-third of the remaining steps. Then I climb one-eight of the rest and stop to catch my breath. What is the least possible number of steps in the staircase?
Given parameters:
First sets of staircase = [tex]\frac{1}{2}[/tex]
Next sets = [tex]\frac{1}{3}[/tex]
Third sets = [tex]\frac{1}{8}[/tex]
Unknown:
The least possible number of steps =?
Solution:
The least possible number of steps will be the lowest common multiples of these sets of steps.
We want fractions that will give whole numbers because realistically, one cannot take half a step of a step.
So, the number of steps must be a multiple of denominators of the fractions given.
Denominators are 2 , 3 and 8
Their least common multiple is 24;
This the lowest number by which 2, 3 and 8 can all divide.
So, the least number is 24 steps

Lydia got her learners permit and helped her parents drive to her grandparent's house and back. It took one hour less time to get there than it did to get back. The average speed on the trip there was 60 km/hour. The average speed on the way back was 40 km/hour. How many hours did the trip there take?
Select the correct response:
2 hours
3 hours
5 hours
4 hours
Using the relation between velocity, distance and time, it is found that the trip took 2 hours.
What is the relation between velocity, distance and time?Velocity is distance divided by time, that is:
[tex]v = \frac{d}{t}[/tex]
On the first part of the trip, a time of t was taken, with an average speed of 60 km/hour, hence:
[tex]60 = \frac{d}{t}[/tex]
d = 60t
On the second part, a time of t + 1 was taken, with an average speed of 40 km/hour, hence:
[tex]40 = \frac{d}{t+1}[/tex]
d = 40(t + 1).
Since the distance is equal for both parts, we can equal the equations and find the time.
60t = 40t + 40
20t = 40
t = 2.
The trip took 2 hours.

If you multiply a number by 3 and then subtract 5, you will get 40 what is the number
Answer:
Number = 15.
Step-by-step explanation:
Given : If you multiply a number by 3 and then subtract 5, you will get 40.
To find : what is the number.
Solution : We have given if you multiply a number by 3 and then subtract 5, you will get 40.
According to question :
Let the number = x
Multiply is with 3 = 3x
Subtract 5 from it we get 40 .
3x -5 = 40
On adding both sides by 5
3x = 45 .
On dividing both sides by 3
x = 15.
Therefore, Number = 15.
Answer:
15
Step-by-step explanation:
3×y-5=40
3y-5=40
3y=40+5

The population of NBA players is Normally distributed
with a mean of 6'7" and a standard deviation of 3. 9
inches. (Wikipedia) Greg is considered unusually tall for
his high school at 6' 3".
1. About what percent of NBA players are taller than Greg?
2. About what percent are shorter?
3. What minimum height would Greg have to be (IN INCHES) in order to be in the top 2. 5% of
NBA player heights?
Using the normal distribution, it is found that:
1. 85% of NBA players are taller than Greg.
2. 15% are shorter.
3. A height of 6'11'' would be needed.
Normal Probability DistributionIn a normal distribution with mean [tex]\mu[/tex] and standard deviation [tex]\sigma[/tex], the z-score of a measure X is given by:
[tex]Z = \frac{X - \mu}{\sigma}[/tex]
It measures how many standard deviations the measure is from the mean. After finding the z-score, we look at the z-score table and find the p-value associated with this z-score, which is the percentile of X.In this problem:
In inches, considering that a feet has 12 inches, the mean is of [tex]\mu = 6 \times 12 + 7 = 79[/tex].The standard deviation is of [tex]\sigma = 3.9[/tex].Greg is 6'3'', that is, X = 6 x 12 + 3 = 75.Item 1:
The proportion is one subtracted by the p-value of Z, hence:
[tex]Z = \frac{X - \mu}{\sigma}[/tex]
[tex]Z = \frac{75 - 79}{3.9}[/tex]
[tex]Z = -1.03[/tex]
[tex]Z = -1.03[/tex] has a p-value of 0.15
1 - 0.15 = 0.85.
85% of NBA players are taller than Greg.
Item 2:
100 - 85 = 15% are shorter.
Item 3:
This is X when Z has a p-value of 1 - 0.025 = 0.975, so X when Z = 1.96.
[tex]Z = \frac{X - \mu}{\sigma}[/tex]
[tex]1.96 = \frac{X - 75}{3.9}[/tex]
[tex]X - 75 = 1.96(3.9)[/tex]
[tex]X = 83[/tex]
83 = 6 x 12 + 11.
A height of 6'11'' would be needed.
