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

What strategy would be the best to solve this problem?
A theater charges $8 for an adult ticket, and $6 for a children's ticket. On a certain day, a total of 255 tickets were sold for a total cost of $1,850. How many more children's tickets were sold than adult tickets?
A. guess, check and revise
B. use a formula
C. work backwards
D. look for a pattern
Answer:
B
Step-by-step explanation:
By making an equation where x = number of adult tickets and y = number of children tickets, we can get 2 equations:
8x + 6y = 1850
x + y = 255
then we solve the equation to get each of the amounts

What is the first step to isolate the variable term on one side of the equation?
Answer:
The basic technique to isolate a variable is to “do something to both sides” of the equation, such as add, subtract, multiply, or divide both sides of the equation by the same number. By repeating this process, we can get the variable isolated on one side of the equation.

Question1Circle A has a diameter of 9 cm. Circle B has a radius of 5 cm. Circle has the larger circumference by centimeters. Use LaTeX: \pi=3.14,Question2 A circle's circumference is approximately 44 cm. Complete each statement using one of these values: 7, 11, 14, 22, 88,138, 154, 196, 380, 616.
a. The circle's diameter is approximately cm.
b. The circle's radius is approximately cm.
c. The circle's area is approximately cm2.
Answer:
1.) CIRCLE B
2.) 14 cm ; 7cm ; 154cm²
Step-by-step explanation:
Given that:
CIRCLE A:
Diameter (d) = 9cm
CIRCLE B:
Radius (r) = 5cm
Circumference of circle A:
Radius (r) = diameter / 2
C = 2 * pi * r = 2 * 3.14 * (9/2) = 28.26 cm
Circumference of Circle B:
C = 2 * pi * r = 2 * 3.14 * 5 = 31.4 cm
CIRCLE B has the larger Circumference.
2.) circle with Circumference (C) = 44cm
Diameter of circle ;
C = 2 * pi * (d/2)
44 = 2 * 3.14 * (d/2)
44 = 6.28d / 2
88 = 6.28d
d = 14.01 = 14.0 cm ( 1 decimal place)
B.) Circle's Radius
Radius = diameter / 2
Radius = 14.0 / 2 = 7 cm
C.) Area (A) of the circle :
A = pi * r^2
A = 3.14 * 7^2
A = 3.14 * 49
A = 153.86
A = 154 cm²

Step-by-step explanation:
Two factory plants are making tb panels. yesterday, plant a produced 18,000 panels. two percent of the panels from plant a and 6% of the panels from plant b were defective. how many panels did plant b produce, if the overall percentage of defective panels from the two plants was 3%?
Plant B produces 6000 panels.
Given that, Plant A produces 18,000 panels out of 2% are defective and 6% of the panels produced by Plant B are defective.
Defective percentage : It is the number of defects divided by the sample size, multiplied by 100. So, if one tool is defective out of a sample size of 1,000, your percent defective is 0.1 percent.
No. of Defective Panels from Plant A + No. of Defective Panels from Plant B = Total No. of Defective panels
Let No. of Panels produced from Plant A = A and No. of Panels produce from Plant B = B
2% of 18000 + 6% of B = 3% of (18000 + B)
360 + 0.06*B = 0.03( 18000 + B)
360 + 0.06* B = 540 + 0.03*B
0.06*B - 0.03B = 540-360
0.03*B = 180
3B = 18000
B = 6000
CHECK:
2% of 18000 + 6% of 6000 = 360+360 = 720 defectives
18000 + 6000 = 24000
720 out of 24000 = 720/24000 = 72/2400 = 3%
Hence, Plant A produces 18000 panels and 2% of them , or 360, are defective.
Plant B produces 6000 panels and 6% of them, or 360, are defective.

A 150-pound person uses 5.1 calories per minute when walking at a speed of 4 mph. How long must a person walk at this speed to use at least 230 calories?
Answer: 45.1 minutes
Step-by-step explanation:
From the question, we are informed that a 150-pound person uses 5.1 calories per minute when walking at a speed of 4 mph. The number of.
minutes that the person must walk at this speed to use at least 230 calories will be:
Let the number of minutes to walk be represented by x
(5.1 × x) = 230
5.1x = 230

Plot the x- and y-intercepts to graph the equation.
Y =
= 1x – 1
Answer:
plot points (0, -1) and (3, 0)
Step-by-step explanation:
compare the given equation to
y=mx +b where b is the y-intercept
y= 1/3 x -1 so thhe y-intercept is at point (0, -1)
to find the x-intercept make y=0
x/3 -1 =0
x/3 =1
x= 3 so x-intercept is at point (3, 0)

Find the slope of the line satisfying the given conditions
a) through (-3,4) and (2,-8)
b) through (5,-3) and (1,-7)
Answer:
a) The slope of the line is [tex]-\frac{12}{5}[/tex]
b) The slope of the line is 1
Step-by-step explanation:
The rule of the slope of a line that passes through points (x1, y1) and (x2, y2) is m = [tex]\frac{y2-y1}{x2-x1}[/tex]
a)
∵ The line passes through points (-3, 4) and (2, -8)
∴ x1 = -3 and y1 = 4
∴ x2 = 2 and y2 = -8
→ Substitute them in the rule of the slope above to find it
∵ m = [tex]\frac{-8-4}{2--3}[/tex] = [tex]\frac{-12}{2+3}[/tex] = [tex]\frac{-12}{5}[/tex]
∴ m = [tex]-\frac{12}{5}[/tex]
∴ The slope of the line is [tex]-\frac{12}{5}[/tex]
b)
∵ The line passes through points (5, -3) and (1, -7)
∴ x1 = 5 and y1 = -3
∴ x2 = 1 and y2 = -7
→ Substitute them in the rule of the slope above to find it
∵ m = [tex]\frac{-7--3}{1-5}[/tex] = [tex]\frac{-7+3}{-4}[/tex] = [tex]\frac{-4}{-4}[/tex]
∴ m = 1
∴ The slope of the line is 1

1.Find the compound interest on Rs25000 for 3 years at 10% per annum ,Compounded annually.
Plzz answer this question in step by step explanation.
Answer:
The compound interest is Rs8275
Step-by-step explanation:
The rule of the compound interest is A = P[tex](1+\frac{r}{n})^{nr}[/tex], where
A is the new amountP is the initial amountr is the interest rate in decimaln is the number of periodst is the timeThe interest I = A - P
∵ The amount of investment is Rs25000 for 3 years
∴ P = 25000
∴ t = 3
∵ The rate of interest is 10% per annum, compounded annually
∴ r = 10% = 10 ÷ 100 = 0.1
∴ n = 1 ⇒ compounded annually
→ Substitute these value in the 1st rule above to find the new amount
∵ A = 25000[tex](1+\frac{0.1}{1})^{1(3)}[/tex]
∴ A = 25000[tex](1.1)^{3}[/tex]
∴ A = Rs33275
→ Use the 2nd rule above to find the interest
∵ I = 33275 - 25000
∴ I = 8275
∴ The compound interest is Rs8275
the perimeters of two squares are in the ratio 2 : 7. What is the ratio of the area of the smaller square to the area of the larger square
The ratio of the area of the smaller square to the area of the larger square, that have a perimeter ratio of 2:7 is 4:49
What is the ratio of the area given the ratio of the perimeters of the squares?The ratio of the perimeter of the squares = 2 : 7
Required: The ratio of the area of the smaller square to the larger square.
Solution: The perimeter of a square of side x is 4•x
The comparative length of the side of each square are therefore;
2/4 and 7/4
The comparative area are therefore;
(2/4)² and (7/4)²The ratio of the areas of the square is therefore;
(2/4)² : (7/4)² = 1/4 : 49/16
Multiplying both sides of the ratio by 16 gives;
