In an orchard of apple and peach trees, 3/7 of the trees are peaches. What is the ratio of apple trees to peach trees?
The ratio of apple trees to peach trees, if 3/7 of the trees are peaches is
4:3.
A ratio compares two quantities by division, with the dividend or number being divided termed the antecedent and the divisor or number that is dividing termed the consequent.
Ratios compare two numbers, usually by dividing them. If you are comparing one data point (A) to another data point (B), your formula would be A/B. This means you are dividing information A by information B.
We have been given that
In an orchard of apple and peach trees, 3/7 of the trees are peaches.
Find out
The ratio of apple trees to peach trees?
To simplify a ratio, divide each number in the ratio by the same amount. To fully simplify a ratio, divide each number in the ratio by their highest common factor. Always keep the numbers in the ratio as whole numbers.
Let the number of total trees in orchard is 7 i.e. denominator of fraction.
Then the no. of peaches tree are 3
so the no. of apple tree in the orchard = 4
Hence , If 3/7 of the trees are peach trees, the ratio of apple trees to peach trees is 4:3.

Line p goes through points (-2,6) and (4, -3). What is the equation of line p?
I need help with Geometry
Answer:
The correct answer is:
Option 2: Yes, because the slopes of lines are negative reciprocals.
Step-by-step explanation:
Given equations of lines are:
Line p: x+2y=1
Line q: y=2x+1
We can determine if two lines are parallel or perpendicular by comparing the slopes of line.
Slope intercept form of line is given by the formula
[tex]y = mx+b[/tex]
Equation of line q is already in slope intercept form.
We have to convert the equation of line p in slope-intercept form
[tex]x+2y = 1\\2y = -x+1\\2y = -\frac{1}{2}x+\frac{1}{2}[/tex]
Slope of line p = 2
Slope of line q = -1/2
We can see that
[tex]2.-\frac{1}{2} = -1[/tex]
The product of slopes of both lines is -1, hence, the lines are perpendicular.
Hence,
The correct answer is:
Option 2: Yes, because the slopes of lines are negative reciprocals.

Damarcus and Xavier went to the arcade to play their two favorite games. Damarcus played 4 rounds of game 1 and 6 rounds of game 2 for $18.00. Xavier played 5 rounds of each game for $20. What is the cost of game 1? A. $1.00 B. $2.00 C. $3.00 D. $4.00
Answer:
The correct option is (c).
Step-by-step explanation:
Let x and y denote the cost of game 1 and game 2 respectively.
ATQ,
4x+6y = 18 ....(1)
5x + 5y = 20 ....(2)
Multiply equation (1) by 5 and equation (2) by 4.
20x+30y = 90 ....(3)
20x + 20y = 80 ....(4)
Subtracting equation (3) and (4)
20x+30y - (20x + 20y) = 90-80
20x-20x+30y-20y = 10
10y = 10
y = 1
Put the value of y in equation (1).
4x+6(1) = 18
4x = 18-6
4x = 12
x = 3
Hence, the cost of game 1 is $3.00
Which of the following best describes how to measure the spread of the data?
The IQR is a better measure of spread for movies than it is for basketball games.
The standard deviation is a better measure of spread for movies than it is for basketball games.
The IQR is the best measurement of spread for games and movies.
The standard deviation is the best measurement of spread for games and movies.
Answer:
C. The IQR is the best measurement of spread for games and movies
Step-by-step explanation:
In a box plot, the Interquartile Range (IQR) can be gotten by finding the range of the rectangular box. That is, The third Quartile (Q3) - the first quartile (Q1).
The IQR is a measure of spread, and it would be appropriate for measuring spread of the data for both Movies and Basketball games displayed by the box plot.

can someone solve x - 8 = -3x + 12
and x + 12 = -x - 6
STEP BY STEP PLEASE? !
Answer:
x-8= -3x+12
adding 8 and 3x on both sides
x-8+8+3x= -3x+3x+12+8
x+3x=20
4x=20 divide by 4
x=5
x+12= -x-6
adding x and subtacating 12 on both sides
x+x+12-12= -x+x-6-12
2x = -18 divide by 2
x= -9
