The right triangle shown below is formed by joining three squares at their vertices. What is the value of x , the side length of the smallest square?
Answer:
B: 8
Step-by-step explanation:
The area of the two smaller squares equals the area of the big square so find the area to the big square
17 * 17 = 289
289 - 225 = 64
The square root of 64 is 8 so the answer is 8.
Please help! It’s saying the answer isn’t 1!!! It’s the last question please helppp!
Answer:
1 and -1
Step-by-step explanation:
The correct answer is 1. The square root of a (real) number is always taken to be the non-negative square root (this allows the square root operation to be a function).
However, if the question is saying it isn't 1, then it wants you to answer 1 and -1, because both square to 1. A better way to word the question would be "For which values of x is x^2 equal to 1?"

HELP (BRAINLIEST ANSWER IF RIGHT)...In a certain Algebra 2 class of 30 students, 7 of them play basketball and 11 of them play baseball. There are 5 students who play both sports. What is the probability that a student chosen randomly from the class plays basketball or baseball?
Answer:
13 / 30
Step-by-step explanation:
The probability an be represented by the number of desirable outcomes over the total outcomes. We know the total is 30 since there are 30 students to be chose from. Now, we need to find the number of students who play basketball and baseball. We can add the two values we are given:
7 + 11 = 18 students
BUT.... we are over-counting the students who play both. We need to subtract those 5 students, since the are counted twice, and that way, they will only be counted once:
18 - 5 = 13 students
Using the formula for probability at the top, we get:
13 / 30

Chang ran three times last week. Here are the distances he ran (in kilometers). 4, 8.36, 18.9 What is the total distance Chang ran on these three days?
Given:
Chang ran three times last week. The distances he ran (in kilometers) are 4, 8.36, 18.9.
To find:
The total distance Chang ran on these three days.
Solution:
It is given that the distances he ran (in kilometers) are 4, 8.36, 18.9.
We need to add these three distances to get the total distance Chang ran on these three days.
[tex]4+8.36+18.9=31.26[/tex]
Therefore, the total distance Chang ran on these three days is 31.26 kilometers.

Answer:
17/12 or 1 5/12
Step-by-step explanation:
You need to make the denominators the same, the common denominator is 12. In the end, they become 9/12 and 8/12. ad those to you get 17/12 or 1 5/12. Was this helpful?
Answer:
=17/12
Step-by-step explanation:
Get a common denominator between the two fractions.
Common denominator will be 12
Multiple 2/3 by 4 (top and bottom) to get 8/12
Multiply 3/4 by 3 (top and bottom) to get 9/12
Add the numerators of both fractions (8+9=17)
final fraction is 17/12 (denominator stays the same)

Given:
The figure of a triangle.
To find:
The measure of angle 1.
Solution:
Exterior angle theorem: In a triangle, the measure of an exterior angle of a triangle is equal to the sum of two opposite interior angles.
Using Exterior angle theorem, we get
[tex]101^\circ =31^\circ +m\angle 1[/tex]
[tex]101^\circ -31^\circ =m\angle 1[/tex]
[tex]70^\circ =m\angle 1[/tex]
Therefore, the measure of angle 1 is 70 degrees.
Which is the correct calculation for the volume of the prism?'
3 units
5 units
4 units
O 3 + 5 + 4 = 12 units
O3(4) + 5 = 17 units?
3(4) = 12 units
3(5)(4) = 60 units
Step-by-step explanation:
V = l.W.H
3(5)(4) = 60 units
The volume of rectangular prism is given by the product of its dimensions hence the correct option is 3(5)(4) = 60 units
What is volume?A volume is simply defined as the amount of space occupied by any three-dimensional solid. These solids can be a cube, a cuboid, a cone, a cylinder or a sphere. Different shapes have different volumes.
Given that, we need to determine the correct calculation for the volume of the prism,
We know that, the volume of a rectangular prism is the product of its dimensions = length x width x height
Therefore, the correct formula is 3(5)(4) = 60 units
Hence, the correct option is 3(5)(4) = 60 units

The stem-and-leaf plot above shows the high temperatures for two cities during a period of 7 days.
What is the difference between the mean temperatures for the two cities?
A. 4.1
B. 5.4
C. 7.0
D. 7.7
Answer:
C: 7.0
Step-by-step explanation:
We are told that; 0|5| means 50 and that |4|8 means 48. Thus;
Temperatures for baker city are;
49, 46, 43, 55, 53, 50, 61
Temperatures for felina are;
48, 54, 54, 58, 62, 63, 67
Thus;
Mean temperature of baker city = (49 + 46 + 43 + 55 + 53 + 50 + 61)/7 = 51°F
Mean temperature of Felina = (48 + 54 + 54 + 58 + 62 + 63 + 67)/7 = 58°F
Thus, difference between the 2 mean = 58°F - 51°F = 7.0°F
using the triangle theorem solve this triangle.
Answer:
b = 4[tex]\sqrt{3}[/tex] , c = 8
Step-by-step explanation:
Using the sine ratio in the right triangle and the exact value
sin30° = [tex]\frac{1}{2}[/tex] , then
sin30° = [tex]\frac{opposite}{hypotenuse}[/tex] = [tex]\frac{4}{c}[/tex] = [tex]\frac{1}{2}[/tex] ( cross- multiply )
c = 8
Using Pythagoras' identity in the right triangle
b² + 4² = 8²
b² + 16 = 64 ( subtract 16 from both sides )
b² = 48 ( take the square root of both sides )
b = [tex]\sqrt{48}[/tex] = [tex]\sqrt{16(3)}[/tex] = 4[tex]\sqrt{3}[/tex]
Answer:
OK THIS IS A BIGGY....c = 8
Step-by-step explanation:
First, find b.
using the pythagorean theorem, a² + b² = c²
to find b using an angle, do b = √(c² - a²)
then, b = a * tan(β)
(β is the angle 30°)
So, b = 6.928
Then, plug it into the pythagorean theorem
4² + 6.928² = c²
16 + 47.997184 = c²
63.997184 = c²
√63.997184 = √c
c = 7.99982399806
Rounded is 8 :)
