2. The ratio of blue marbles to yellow marbles is 5:1. For every yellow marble, there are ___ blue marbles.
Answer:
1.)8 boys yo 9 girls
2.)5
Step-by-step explanation:
1)divide by 2
2.) every yellow marble is 1 and there is 5 marbles for each yelllow marble
The ratio of boys to girls in the Grade 6 math class is =
8 : 9.
For every yellow marble, there are five blue marbles.
To find the ratio of a given two quantities how many times one quantity is greater or smaller than the other.
To find the ratio of boys to girls in Grade 6 math class simplify by dividing through with two.
Therefore, 16/18 = 8/ 9, that is 8 boys is to 9 girls.
The 5:1 ratio of blue to yellow marbles means for every yellow marble, there are five blue marbles.

In triangle ABC, A is a right angle and M B=45°. Find BC. If you answer is not an integer, leave it in simplest radical form.
Step-by-step explanation:
- In a right triangle, if ∠B is 45°, then ∠C is too.
-- Since ∠B and ∠C are equal, the sides opposite them
are equal too. This is an isosceles right triangle. Its legs
are equal.
-- (The hypotenuse)² = (one leg)² + (the other leg)²
= (12-ft)² + (12-ft)²
= (144 x 2)
The hypotenuse = √(144 x 2) = 12√2 .

Calculate the gradient of the line using rise/run method.
Given:
The graph of line.
To find:
The gradient of the line using rise/run method.
Solution:
We know that the gradient of a line is also known as slope.
[tex]Slope=\dfrac{Rise}{Run}[/tex]
Consider the two intercepts, then rise is distance between origin and y-intercept and run is the distance between origin and the x-intercept. But rise must be negative because the value of y decreased from 3 to 0.
[tex]Rise=-3[/tex]
[tex]Run=2[/tex]
Now,
[tex]Slope=\dfrac{Rise}{Run}[/tex]
[tex]Slope=\dfrac{-3}{2}[/tex]
The gradient of the line is [tex]-\dfrac{3}{2}[/tex].
Therefore, the correct option is C.

Step-by-step explanation: took the test got it right
The required measurement closest to the area of the circle in square centimeters is 78.5cm². Option B is correct.
What is an area circle?The area of the circle is given by the pie times square of the radius.
Area of circle = πr^2
Here,
Let the radius of the given circle be r = 5 cm
Area of the circle = πr²
Substitute the value in the above expression,
Area of the circle = π 5²
Area of the circle = 78.5cm²
Thus, the required measurement closest to the area of the circle in square centimeters is 78.5cm². Option B is correct.

Write an equation to represent 'twice a number (x) is fifty"
Answer:
2x=50
Step-by-step explanation:
Hi there,
Your question is "twice a number (x) is fifty"
Recall how a number is represented by x.
Twice a number would be represented as 2x.
Therefore, to represent that twice a number is equal to 50, that would result in the expression: [tex]2x=50[/tex]
If you're looking to solve this equation, it's often best to think about the "reverse" of the current equation.
Notice how 2 is multiplying the x.
To isolate x, divide that side by 2.
However, recall that whatever is done to one side of an equation must also be done to the other side of the equation. Therefore, you will need to divide both sides by 2.
[tex]2x=50[/tex]
[tex]\frac{2x}{2} = \frac{50}{2}[/tex]
[tex]x=25[/tex]
Equation: [tex]2x=50[/tex]
Solving for x: 25

Answer:
-8 + 12n
Step-by-step explanation:
First term = a = 4
Common difference = d = second term - first term
= 16 - 4
= 12
Nth term = a + (n -1) *d
= 4 + (n - 1)*12
= 4 + n*12 - 1*12
= 4 + 12n - 12
= 4 - 12 + 12n
= -8 + 12n

A bag contains 42 red, 45 green, 20 yellow, and 32 purple candies. You pick one candy at random. Find the
probability that it is purple or not red.
Answer:
97/139
Step-by-step explanation:
You add every thing but red so 45+20+32 which equals 97, so 97 is your numerator and to get the denominator you add all the numbers together so 42+45+20+32 which equals 139.
Probability that candy picked is purple or not red is [tex]\frac{32}{151}[/tex].
What is probability?The probability of an event can be calculated by probability formula by simply dividing the favorable number of outcomes by the total number of possible outcomes. The value of the probability of an event to happen can lie between 0 and 1 because the favorable number of outcomes can never cross the total number of outcomes. Also, the favorable number of outcomes cannot be negative.
According to the question
A bag contains 42 red, 45 green, 20 yellow, and 32 purple candies.
You pick one candy at random.
We have to find probability that it is purple or not red.
Formula for probability:
[tex]P(E) = \frac{Number \ of \ favorable \ outcomes}{Total \ number \ of \ favorable \ outcomes}[/tex]
Total number of favorable outcomes = [tex]42+45+20+32 =151[/tex]
Number of favorable outcomes = 32
Probability that it is purple or not red.
[tex]P(E)=\frac{32}{151}[/tex]
Hence, Probability that candy it is purple or not red is [tex]\frac{32}{151}[/tex].
