Alex has a bag of marbles. Each marble is red, blue, or yellow , and the ratio of the red to blue to yellow marbles is 6:10:15. After Alex adds 10 red marbles and removes 25 yellow marbles form the bag, the ratio of red to blue to yellow is 2:3:4. How many blue marbles are in Alex's bag
Answer:
There are 150 blue marbles in Alex's bag.
Step-by-step explanation:
Let [tex]x[/tex], [tex]y[/tex], [tex]z[/tex] be the quantities of red, blue and yellow marbles, respectively. From statement we derive three rational equations for initial and final ratios:
Initial ratio
[tex]\frac{x}{y} = \frac{6}{10}[/tex] (1)
[tex]\frac{y}{z} = \frac{10}{15}[/tex] (2)
Final ratio
[tex]\frac{x + 10}{z - 25} = \frac{1}{2}[/tex] (3)
After some algebraic handling we get the following system of linear equations:
[tex]x - \frac{3}{5}\cdot y = 0[/tex] (1)
[tex]y - \frac{2}{3}\cdot z = 0[/tex] (2)
[tex]2\cdot (x + 10) = z - 25[/tex]
[tex]2\cdot x +20 = z - 25[/tex]
[tex]2\cdot x - z = -45[/tex] (3)
The solution of the system of linear equations is:
[tex]x = 90[/tex], [tex]y = 150[/tex], [tex]z = 225[/tex]
There are 150 blue marbles in Alex's bag.

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.

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.

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

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)

(b) An angle measures 77º. What is the measure of its supplement?
Answer:
103
Step-by-step explanation:
We know supplementary angles equal 180 degrees. So the problem will be: 180 - 77 = 103
Answer:
103 degrees
Step-by-step explanation:
Supplementary angles add up to 180 degrees. Thus, the supplement of 77 degrees is (180 - 77) degrees, or 103 degrees.

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.
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 :)
