Write a simplified expression for the right half of the equation that can be used to find the nth term in the sequence The sequence is 7,9,11,13,15
Answers
7,9,11,13,15
First, find the common difference (d)
9-7 = 11-9 = 13-11 = 15-13 = 2
d= 11
a1 = first term = 7
apply the formula:
an = a1 + (n-1) d
an = 7 + (n-1) 2
an = 7 + 2n-2
an = 2n + 5

60 pieces of fruit. How many pieces of each type of fruit are there?
Answers
The number of mangoes = 48
The number of grapefruit = 12
What is an expression?
Mathematical expression is defined as the collection of the numbers variables and functions by using operations like addition, subtraction, multiplication, and division.
Given that;
A box of fruit has four times as many oranges as grapefruit.
And, Total number of fruit = 60 pieces
Now,
Let number of grapefruit = x
Then, Number of Mangoes = 4x
So, We can formulate;
⇒ x + 4x = 60
Solve for x as;
⇒ 5x = 60
⇒ x = 12
Thus, Number of grapefruit = x
= 12
Then, Number of Mangoes = 4x
= 4 × 12
= 48
Therefore, The number of mangoes = 48
The number of grapefruit = 12

Answers
Answer: "If my bill is not expensive. I did not use my cell phone too much"
Reason:
The original statement is of the form "If P, then Q"
P = "I use my cell phone too much"
Q = "my bill will be expensive"
An equivalent form to the original condition is known as the contrapositive of the form "If not Q, then not P". We swap the positions of P and Q. We also negate each part. You can use a logical truth table to verify that the conditional and contrapositive have equivalent truth values, which means they are effectively equivalent statements.

Jenny’s rectangular bedroom has one wall that is 5 feet long. The distance from one corner of the bedroom to the other corner is 13 feet. How long is the other wall?
Answers
The other wall is 12 feet long can be evaluated using Pythagoras theorem.
What is Pythagoras theorem?
The hypotenuse's square is equal to the sum of the squares of the other two sides if a triangle has a straight angle (90 degrees), according to the Pythagoras theorem. Keep in mind that BC2 = AB2 + AC2 in the triangle ABC signifies this. Base AB, height AC, and hypotenuse BC are all used in this equation. The longest side of a right-angled triangle is its hypotenuse, it should be emphasized.
Here given in the question that one side of the wall 5 feet
So as it is a rectangular bedroom it can be split into 2 right-angled triangles.
So the hypotenuse of the triangle is 13 feet
Now using the Pythagoras theorem we can find out the length of the other wall
b²=h²-p²
b²=13²-5²
b²=169-25=144
b=√144
b=12 feet
Hence the other wall is 12 feet long.

Answer: 4.38
Step-by-step explanation:
Firstly to answer this question we need to take a look at both of the mpg for each of them. We already know that the SUV has 25 mpg and the Sedan has 32 mpg, to figure this out we need to get the answer to $4 x 25 and $4 x 32.
The answer to that is $100 for the SUV and $128 for the Sedan. Next, we need to figure out the mile difference between to 2 vehicles.
100 x 2 = 200
128 x 2 = 256
knowing those numbers overall we can conclude that the sedan will cost $4.38 less than the Suv

The family of all linear equations that are parallel to y=-1/2x-2 is defined as:

Such that b ≠ -2.
Which lines are parallel to the given one?We know that a general linear equation is written in the slope-intercept form as:
y = m*x + b
Where m is the slope and b is the y-intercept.
We know that two linear equations are parallel if and only if the lines have the same slope and a different y-intercept.
So the family of lines parallel to:

We would apply the formula for calculating the expectation of the mean or expected value which is expressed as
Ex = ΣxP(x)
In this scenario, from the information given,
12000 is profit at 50%
Breakeven mean = 0 because there is no profit or loss' at 20%
loss = - 6600 at 30 %
Thus,
Expectation = 50/100 * 12000 + 20/100 * 0 + 30/100 * 6600
Expectation = 6000 + 0 + 1980
Expectation = 7980

Angles abc and bcj are alternate interior angles. use a transformation that takes angle abc to angle bcj to prove that alternate interior angles are congruent
Answers
Angle two and angle six line up with one another. Angle three would consequently be consistent with angle six. Angles two and three are congruent because they both have vertical angles.
What are the alternate interior angles?Alternate internal angles are the pair of angles formed on the inner side of the parallel lines and on the opposing sides of the transversal when two parallel lines are intersected by a transversal. These angles are all equal. There is an alternative perspective on this. The parallelism or non-parallelism of the provided lines can be determined by the alternative inner angles. If these angles are equivalent, the given lines that a transversal crosses are said to as being parallel.
To see the many internal angles, look at the following diagram. Here, a transversal divides AB and CD, two parallel lines.
Alternate Interior Angles Theorem's opposite, then?The two lines are said to be parallel if a transversal intersects them such that their alternate interior angles are equal, according to the converse of the alternate interior angles theorem.
Let's examine the following diagram to better comprehend this: 1 = 5 (matching angles), 3 = 5 (vertically opposite angles). Thus, ∠1 = ∠3. The same goes for the demonstration of 2 = 4. This demonstrates that the two supplied lines are parallel to one another since their alternate inner angles are equal.
Example: Two lines are parallel to one another if the alternate interior angles created by the transversal line on two coplanar are congruent. As a result, we can write that 2 and 5 are corresponding angles.
Transformations would show that the accompanying exterior angles EBI and BCJ are congruent, proving that an is parallel to a pair of alternate exterior angles with measurements of 130° and 50°.

7/20 of the laundry still needs to be washedStep-by-step explanation:
Laundry washed:
2/5 and 1/4 of totalWho washed more?
Compare the fractions by bringing them to common denominator:
2/5 = (2*4)/(5*4) = 8/20,1/4 = (1*5)/(4*5) = 5/20.Compare the numerators:
8 > 5,It means Mrs. Stem washed more than laundry her son.
Total portion of laundry washed:
8/20 + 5/20 = 13/20Laundry left to wash is the difference of full and the fraction of washed laundry:
1 - 13/20 = 20/20 - 13/20 =(20 - 13)/20 = 7/20Answer:
7/20 of laundry is still pending.
Step-by-step explanation:
Now the both washed is,
→ (2/5) + (1/4)
→ ((2 × 4)/(5 × 4)) + ((1 × 5)/(4 × 5))
→ (8/20) + (5/20)
→ 13/20
Forming the equation,
→ (13/20) + x = 1
Then required value of x will be,
→ (13/20) + x = 1
→ x = 1 - (13/20)
→ x = (20/20) - (13/20)
→ x = (20 - 13)/20
→ [ x = 7/20 ]
Hence, 7/20 of laundry is pending.

Objective function Z=3x+6yFind the value at each corner of the graph
Answers
Given: An objective function

Explanation: The inequalities can be graphed by considering them as equations and then determining the shaded region by less than or greater than symbol.
The equation for the first inequality is-
[tex]2x+y=12[/tex]This represents a straight line passing through points (6,0) and (0,12).
The shaded region will be below this line as the inequality is-
[tex]2x+y\leq12[/tex]Similarly, the inequality-
[tex]x+y\ge6[/tex]Represents a shaded region above the line x+y=6.
The inequalities-
[tex]x\ge0,y\ge0[/tex]Represents the positive values of x and y. Hence we need to determine the graph in the first quadrant.
The graph of the inequalities is-
The graph in blue represents the inequality-
[tex]2x+y\leq12[/tex]While the graph in green represents the inequality-
[tex]x+y\ge6[/tex]The corner points of the common shaded area are A(0,6), B(0,12), and C(6,0).
Now the value of the objective function at these points is-
a) At A(0,6)
[tex]\begin{gathered} z=3(0)+6(6) \\ =36 \end{gathered}[/tex]b) At B(0,12)

When spinning a wheel with 1 red, 2 blue, and 3 green spaces, what
is the probability that you will not spin a red?
Answers
Step-by-step explanation:
so, we have 1 + 2 + 3 = 6 total spaces.
a probability is always the ratio
desired cases / totally possible cases
the probability to spin red is therefore
1 desired case
6 total possible cases
1/6 = 0.166666666...
a probability of 1 means a sure result = anyone of the totally possible cases.
so, 6/6 = 1 in our case.
if the desired cases are everything but red, we need to eliminate the possible red results (1) from the amount of our desired cases : 6 - 1 = 5
so the probability of not spinning a red is
5/6 = 0.833333333...
formally we can also say this is the sure thing minus the opposite of what we want to have. the opposite of not spinning a red is spinning a red (1/6) :
1 - 1/6 = 5/6 = 0.833333333...
