Answer:
The total number of blue marbles = 24Step-by-step explanation:
Total number marbles Stacia has = 28
The ratio of red to blue marbles = 1 : 6
Let 'r' be the number of red marbles.Let 'b' be the number of blue linesAs the total number of marbles is 28. Thus,
r + b = 28
As the ratio of red to blue marbles is 1 to 6.
It means for each red marble 'r', we have 6 blue 'b' marbles. Thus,
b = 6r
now substituting b = 6r in the equation r + b = 28
r + b = 28
r + 6r = 28
7r = 28
divide both sides by 7
7r/7 = 28/7
r = 4
Thus,
The total number of red marbles ⇒ r = 4
The total number of blue marbles ⇒ b = 6r = 6(4) = 24
Therefore,
The total number of blue marbles = 24In ΔOPQ, p = 7.2 cm, ∠P=36° and ∠Q=38°. Find the length of q, to the nearest 10th of a centimeter.

What is the least common denominator? *
1 2
and
5 3
Answer:
To get the Least Common Multiple (LCM) of 12 and 53 we need to factor each value first and then we choose all the factors which appear in any column and multiply them:
12: 223
53: 53
LCM: 22353
The Least Common Multiple (LCM) is: 2 x 2 x 3 x 53 = 636

Find the measure of each angle indicated. Show work.
Answer:
? = 109 degrees
Step-by-step explanation:
45 + 75 + _ = 180 ( look for vertical angles)
45 + 75 + 60 = 180
60 +79 + _ = 180 (look for a straight line that forms 180 degrees)
60 + 79 + 41 = 180
68 + 41 + _ = 180 (look for a triangle that adds up to 180)
68 + 41 + 71 =180
180 - 71 = 109 (look for a linear pair)
As a estimation we are told £3 is €4. Convert £25.50 to euros €
Answer:
£34
Step-by-step explanation:
→ Find how euros is in a pound
£3 = €4
£1 = €1.33
→ Multiply the euro by 25.50
1.33333 × 25.50 = £34
Answer:
€34
Step-by-step explanation:
First you'll want to find out how much £1 is.
Since we know £3 is equal to €4 we can:
divide £3 by 3 = £1divide €4 by 3 = €1.33So, £1 = €1.33
With this in mind, we can find out what £25.50 is:
£1 x 25.50 = £25.50€1.33 x 25.50 = €34Therefore, £25.50 = €34

Find the average rate of change for f(x) = x^2 − 3x − 10 from x = −5 to x = 10.
A) -1
B) -2
C) 1
D) 2
Answer:
D) 2
The average rate of change of f(x)
A(x) =2
Step-by-step explanation:
Step(i):-
Given that the function f(x) = x² - 3x -10
Given x =a = -5 and y = b = 10
The average rate of change of f(x)
[tex]A(x) = \frac{f(b)-f(a)}{b-a}[/tex]
Step(ii):-
f(x) = x² - 3x -10
f(-5) = (-5)² - 3(-5) -10 = 25+15-10=30
f(10) = (10)² -3(10)-10 = 100 -30 -10 =60
The average rate of change of f(x)
[tex]A(x) = \frac{f(b)-f(a)}{b-a}[/tex]
[tex]A(x) = \frac{60-30}{10-(-5)}= \frac{30}{15} = 2[/tex]
A(x) =2

6x-18=54 what does the x represent
Answer:
x=12
Step-by-step explanation:
I attached a picture for the steps
Simplifying
6x + -18 = 54
Reorder the terms:
-18 + 6x = 54
Solving
-18 + 6x = 54
Solving for variable 'x'.
Move all terms containing x to the left, all other terms to the right.
Add '18' to each side of the equation.
-18 + 18 + 6x = 54 + 18
Combine like terms: -18 + 18 = 0
0 + 6x = 54 + 18
6x = 54 + 18
Combine like terms: 54 + 18 = 72
6x = 72
Divide each side by '6'.
x = 12
Simplifying
x = 12
Final Result: 12
Mr. Shaw wants to replace the flooring his family room. The floor has an area of 262.8 square feet. If the room is 18 feet long, how wide is it? Justify your procedure.
Answer:
14.6
Step-by-step explanation:
The area of a rectangle is area=length*width
so we can substitute the numbers here, 262.8=18w
divide 262.8 by 18 to isolate the variable.
You get 14.6.
The width is 14.6.

Answer: D.) y = 2x + 1
Step-by-step explanation:
in slope-intercept form, y = mx + b, m is the slope, Rise/Run
The difference in y-values, rise, increases by 2 for every increase of 1 in x-values, the run.
2/1 is the slope
m = 2
b is the y-intercept
To calculate b, substitute any pair of y and x values from the chart, and the value 2 for m:
9 = 4(2) + b
9 = 8 + b
1 = b
Rewrite the equation with the values calculated for m and b. Keep y and x
y = 2x + 1

Answer:
The population is: all glass recycled
The sample is: the 10 selected glass items.
The parameter is the proportion of: all his glass that is clear
The statistic is the proportion of: the selected glass that is clear
The population of a distribution is the entire group, while the sample is the selected group from the entire group.
The population is all glass recycled The sample is the 10 selected glass items. The parameter is the proportion of all his glass that is clear The statistic is the proportion of the selected glass that is clearThe population
From the question, we understand that glasses are recycled and then separated into colors.
This means that, the population is all glass recycled
The sample
From the question, we understand that he randomly grabs 10 glass items, and then determine the proportion of clear glasses.
This means that, the sample is the 10 selected glass items.
The parameter
This is the value that summarizes all the glasses that are being recycled.
So, the parameter is the proportion of all his clear glasses
The statistic
This is the value that summarizes the selected glasses.
So, the statistic is the proportion of the selected glass that is clear
