Rudolph is collecting Christmas trees to donate to needy families. He collects 31 trees He donates all of his trees to 3 of his friends Frazer gets 3 more trees than Sally Sally gets 7 fewer trees than flame How many trees do each of his friends get?
Answer:
Frazer = x = 10 trees
Sally = y = 7 trees
Frame = z = 14 trees
Step-by-step explanation:
We have 3 friends
They are represented by:
Frazer = x
Sally = y
Frame = z
Total number of trees donated = 31
Rudolph is collecting Christmas trees to donate to needy families. He collects 31 trees He donates all of his trees to 3 of his friends
Frazer gets 3 more trees than Sally
x = y + 3
Sally gets 7 fewer trees than Flame
y = z - 7
z = y + 7
How many trees do each of his friends get?
x + y + z = 31
y + 3 + y + y + 7 = 31
3y + 10 = 31
3y = 31 - 10
3y = 21
y = 21/3
y = 7 trees
x = y + 3
x = 7 + 3
x = 10 trees
z = y + 7
z = 7 + 7 trees
z = 14 trees
Therefore:
Frazer = x = 10 trees
Sally = y = 7 trees
Frame = z = 14 trees

Avi's pet hamster Chubby loves to run in his hamster wheel. During one "race", Avi counts 100 rotations of the wheel. She wants to know how far Chubby ran, so she measures the diameter of the wheel and finds that it is 20 cm. How far did Chubby run? Round your answer to the nearest cm
Answer:
Chubby ran a distance of 6,283 m
Step-by-step explanation:
The length of one run is simply equal to the circumference of the circle
Mathematically, C = pi * d
C = 22/7 * 20 = 62.83 cm
So if one rotation is a distance of 62.83 cm, then 100 rotations will be a distance of;
62.83 * 100 = 6,283 m

Look at the system of equations. One of them is
Y =-x-2
What is the other equation? Write in slope-intercept form. Start with y =
Please help:)
Answer:
y=4x+3
Step-by-step explanation:
The given equation y=-x-2 is the equation of the line passing through the points (-1,-1) and (-2,0) in the given graph.
From the graph, the other line is passing through the points (0,3) and (-1,-1).
So, the equation of the line passing through the two points is
[tex]y-3=(x-0)\times \frac{-1-3}{-1-0} \\\\y-3=x \times \frac{-4}{-1} \\\\y-3= x \times4 \\\\y=4x+3[/tex]
Hence, the equation of the other line is y=4x+3.

What is the value of x in this triangle?
Enter your answer in the box.
The value of x in the given triangle is 61
From the question, we are to calculate the value of x in the given triangle.
In a given triangle ABC, with interior angles A, B, and C, the sum of the angles is 180°.
That is,
∠A + ∠B + ∠C = 180°
Thus,
In the given triangle,
37° + 82° + x° = 180° (Sum of angles in a triangle)
Solve for x in the in the equation above
37° + 82° + x° = 180°
Add the numbers
119° + x° = 180°=
Subtract 119° form both sides
119° - 119° + x° = 180° - 119°
x° = 61°
Hence, the value of x in the given diagram is 61

Six checkers are placed in three boxes: two red are in a box labeled "RR"; two black are in a box labelled "BB"; a red and a black are in a box labelled "RB". How can you tell, by taking only one checker out of one of the boxes (and without looking at any of the other checkers), the correct content of all three boxes?
Answe and Step-by-step explanation:
Looking at the question the way it was asked, it is easy because it said they have been labelled, so you don't have to stress yourself. Although, if what is intended is, the labelling got wrong along the way and how do you identify the correct one? Then this is what to do:
Go to the one labelled RB. Since I'm assuming that the labelling got wrong, if you pick a red, it means what we have should be a RR and if we picked a black, it means what we have is a BB and we can't have a RB because it was labelled wrongly.
Let's assume he saw a red,
We know that the BB box was labelled wrongly, and we already determined that the box with RB is a RR. Therefore, the box BB can never be RR(because we've seen it already) and it's certainly not BB (due to the fact that they were labelled wrongly). So we have only one option left which is it being RB and whatever we have left will be BB.
If we assume what was picked from the wrongly labelled RB is black.
We know that the RR box was labelled wrongly, and we already determined that the box with RB is a BB. Therefore, the box RR can never be BB and it's certainly not RR (due to the fact that they were labelled wrongly). So we have only one option left which is it being RB and whatever we have left will be RR.

Answer:
12
Step-by-step explanation:
When the numerators are the same, the denominator that is bigger has a lesser value. In this case, the inequality > shows that [tex]\frac{1}{10}[/tex] is bigger than the fraction next to it so in order to find a fraction that is lesser in value than [tex]\frac{1}{10}[/tex], we need to find a denominator that is more than 10, since 10 is the denominator of the first fraction. The only number more than 10 in the options is 12, so 12 is the answer.

Another line labeled q goes through (0, 2) and (2, minus 4). Both lines intersect at X-axis at 1 and Y-axis at minus 1. The slope of line p is , and the slope of line q is .
The slope of line p is: 3
The slope of line q is: -3.
How to Find the Slope of a Line?To find the slope (m) of any given line, what we need is the coordinates of any two points on the given line. The formula to apply to find the slope (m) of the line is given as:
Slope (m) = change in y / change in x = y2 - y1 / x2 - x1.
Slope (m) of line p with points (2, 2) and (0, -4):
Slope (m) of line p = -4 - 2 / 0 - 2 = -6/-2
Slope (m) of line p = 3
Slope (m) of line q with points (0, 2) and (2, -4):
Slope (m) of line q = -4 - 2 / 2 - 0 = -6/2
Slope (m) of line q = -3

When checking lightbulbs, a salesclerk found that 15% of the 680 he checked were defective. How many of the lightbulbs were found defective?
Answer: 102 lightbulbs were found by the detective.
Step-by-step explanation:
Answer:
102 lightbulbs.
Step-by-step explanation:
To get the answer you have to read into the problem this is important on things like this. These are the key words you need to look for, (Checked), (Defective) as well as the percentages and numbers so 15% and 680 are important as well. In the problem is says the "a salesclerk found that 15% of 680 lightbulbs were defective" then it ask "how many lightbulbs were found to be defective" because he said that 15% of the 680 were defective you have to find out what number makes up that 15% of the defective bulbs, In order to do this you 1.) turn 15% into a decimal making it .15
2.) You multiply your decimal by your total which is 680 so it would like this .15 x 680 this would = 120
so your answer is 120.
this is better explanation NOTE THIS IS A EXAMPLE THIS IS NOT THE ANSWER PROBLEM!!!
How to calculate percentage of a number. Use the percentage formula: P% * X = Y
Example: What is 10% of 150?
Convert the problem to an equation using the percentage formula: P% * X = Y
P is 10%, X is 150, so the equation is 10% * 150 = Y
Convert 10% to a decimal by removing the percent sign and dividing by 100: 10/100 = 0.10
Substitute 0.10 for 10% in the equation: 10% * 150 = Y becomes 0.10 * 150 = Y
Do the math: 0.10 * 150 = 15
Y = 15
So 10% of 150 is 15
Double check your answer with the original question: What is 10% of 150? Multiply 0.10 * 150 = 15
