You eat ripe tomatoes on July 29. When did you plant the tomato seeds?
You planted the tomato seeds on the 10th of May
How to determine when you planted the seeds?The complete question is added at the end of this solution
From the question, we have the following parameters that can be used in our computation:
Number of days to ripe = 80 days
Date the tomato seed is eaten = July 29
The above parameters can be represented using the following subtraction equation:
The date you planted the seeds = Date the tomato seed is eaten - Number of days to ripe
Substitute the known values in the above equation, so, we have the following representation
The date you planted the seeds = July 29 - 80 days
Evaluate the difference
So, we have the following representation
The date you planted the seeds = May 10
Hence, the date you planted the seeds is May 10

Probability of landing on red 0.9%, when Yolanda spun the dial 1000 times.
What is probability?
The probability of an event can be calculated using the probability formula by simply dividing the favorable number of possibilities by the total number of outcomes. The likelihood of an event occurring can be anywhere between 0 and 1, as the favorable number of outcomes can never exceed the total number of outcomes.
A spinner with 10 equally sized slices has 4 yellow slices, 4 red slices, and 2 blue slices.

Find the missing ange:
RPQ =______
The value of angle RPQ in the circle is 115 degrees.
How to find the angle in the circle?The intersecting chords theorem, also known as the chord theorem, is an elementary geometry statement that describes a relationship between the four line segments formed by two intersecting chords within a circle.
If two chords intersect inside a circle, then the measure of the angle formed is one half the sum of the measure of the arcs intercepted by the angle and its vertical angle.
Therefore,
∠RPQ = 1 / 2 (arc angle RQ + arc angle SA)
arc angle RQ = 175 degrees
arc angle SA = 55 degrees
Hence,
∠RPQ = 1 / 2 (175 + 55)
∠RPQ = 1 / 2 (230)
∠RPQ = 115 degrees.

You have a carryover balance of $600 on a credit card that has a 18.99% annual percentage rate (APR). You have a recurring monthly purchase of $70 for your water bill and you make a payment of 7% of the ending balance is made each month. Complete the table below. Round each value to the nearest cent.
The completion of the credit card table is as follows:
Month Carryover Finance New Ending
Balance Charge Purchase Balance Payment
1 $600 $10.60 $70 $680.60 $47.64
2 $632.96 $11.12 $70 $714.08 $49.99
How are credit card finance charges computed?Credit card attracts finance charges.
The finance charges are the interest for using some credit to finance purchases.
Most finance charges are based on the annual percentage rate (APR), which may also be used to obtain the monthly percentage rate (MPR) by dividing the APR by 12.
The finance charge is applied to the unpaid balance at the end of the period, which may be daily, weekly, or monthly.
Carryover balance = $600
Annual percentage rate (APR) = 18.99%
Monthly percentage rate (MPR) = 1.5825% (18.99% ÷ 12)
Recurring monthly purchase = $70
Monthly payment = 7% of the ending balance
The finance charge for month 1 = $10.60 ($600 + $70 x 1.5825%)
Payment for month 1 = $47.64 ($680.60 x 7%)
Carryover balance for month 1 = $632.96 ($680.60 - $47.64)
The finance charge for month 2 = $11.12 ($632.96 + $70 x 1.5825%)
Payment for month 2 = $47.64 ($714.08 x 7%)

slide and its ladder form a right triangle with the ground, with the
slide representing the hypotenuse. The top of the ladder is 10 feet above
the ground, and the bottom of the ladder is 12 feet from the bottom of
the slide. What is the length of the slide to the nearest tenth of a foot?
1. Use the information in the problem to label the diagram.
Answer:
1. The problem involves finding the length of a slide about a ladder. The slide and the ladder form a right triangle, with the ground and the slide as the hypotenuse.
2. The top of the ladder is 10 feet above the ground, and the bottom of the ladder is 12 feet from the bottom of the slide.
3. In order to solve this problem, a diagram can be used to represent the scenario.
4. Label the bottom of the slide as point A, the bottom of the ladder as point B, and the top of the ladder as point C.
5. Draw a straight line from point A to point B and label it 12 feet.
6. Draw a straight line from point B to point C and label it 10 feet.
7. Draw a straight line from point A to point C, which is the hypotenuse of the triangle.
8. Use the Pythagorean Theorem to find the length of the hypotenuse.
9. The Pythagorean Theorem states that a2 + b2 = c2, where a and b are the sides of the triangle and c is the hypotenuse.
10. In this problem, a is 12 feet, and b is 10 feet. Plugging these values into the equation, we get 122 + 102 = c2. Solving for c, we get that the length of the slide is 14.04 feet to the nearest tenth of a foot.

If there are 16 ounces in one pound, how many ounces of raisins will 108 pounds of grapes yield
Answer:
1728
Step-by-step explanation:
Just multiply 108 by 16.
Answer:
384 ounces
Step-by-step explanation:
If it takes 4 1/2 pounds of grapes to make 1 pound of Rasins, then we need to figure out how many pounds of Rasins we can make with 108 pounds of grapes.
(Or you can do 108 divided by 4 1/2)
4 1/2 x 10 = 45
4 1/2 x 4 = 18
45 + 45 + 18 = 108
10 + 10 + 4 = 24
(Looking at the work you did above, we can take 54, and multiply that by 2 to get 108, therefore, we can just multiply 12 by two to get 24)
Now we need to convert the pounds to ounces.
If one pound is equal to 16 ounces, then we can use the equation,
24 x 16 = 384
108 pounds of grapes yields 384 ounces.
NO LINKS!! What are the true converses for each theorem?
Answers:
If the alternate interior angles are congruent, then the lines are parallel.If the alternate exterior angles are congruent, then the lines are parallel.If the corresponding angles are congruent, then the lines are parallel.If the consecutive interior angles are supplementary, then the lines are parallel.If the consecutive exterior angles are supplementary, then the lines are parallel.=====================================================
Explanation:
A conditional statement is of the form "if..., then..."
For example, "If it rains, then the grass gets wet" is a conditional statement.
We can have a basic template of "If P, then Q" to represent any conditional. The P and Q are placeholders for logical statements.
The converse of that conditional is "If Q, then P". We swap P and Q.
------------
So let's say we had this original conditional:
"If the lines are parallel, then alternate interior angles are congruent"The converse would be:
"If the alternate interior angles are congruent, then the lines are parallel"Similar ideas apply for the other converses as well.
Answer:
If alternate interior angles are congruent, then lines are parallel.
If alternate exterior angles are congruent, then lines are parallel.
If corresponding angles are congruent, then lines are parallel.
If consecutive interior angles are supplementary, then lines are parallel.
If consecutive interior angles are supplementary, then lines are parallel.
Step-by-step explanation:

y-intercept means Isaiah sells $0, then the company will pay him $85.
Write an equation of the line that passes through the pair of points. (5/12, −1), (−3/4, 1/6)
The equation of the line can be written as y = -x - (7/12).
What is the equation of a line?A line is a one-dimensional shape that is straight, has no thickness, and extends in both directions indefinitely. The equation of line is given by,
y =mx + c
where,
x is the coordinate of the x-axis,
y is the coordinate of the y-axis,
m is the slope of the line, and
c is y-intercept.
Given that the line passes through (5/12, −1) and (−3/4, 1/6). Therefore, the slope of the line can be written as,
Slope of the line = [(1/6) - (-1)] / [(-3/4) - (5/12)]
= [(1/6) + 1] / [(-3/4) - (5/12)]
= (7/6) / [(-9-5)/12]
= (7/6) / (-14/12)
= -1
Now, the equation can be rewritten with slope and a point as,
y = mx + c
(1/6) = -1(-3/4) + C
(1/6) = (3/4) + C
C = (1/6) - (3/4)
C = (2/12) - (9/12)
C = (-7/12)
Therefore, the equation of the line can be written as,
y = mx + c
y = (-1)x + (-7/12)
y = -x - (7/12)
Hence, the equation of the line can be written as y = -x - (7/12).

What are inverse statements?Two assertions that are logically opposed to one another are referred to be inverse statements. An inverted statement would be "It is raining" and "It is not raining."Biconditional statements can be both true and untrue depending on the veracity or falsity of each of its component elements. For instance, "If it is raining, then the ground is wet" is a biconditional statement because if it is raining, the ground will be wet, and if it is not raining, the ground won't be wet. In other words, the truth or falsehood of the first part (it is raining) determines the truth or falsehood of the second part.
