Tayloe travels 35 miles every 2 days to work. how many days would it take him to travel 100 miles . answer in fraction
The number of days Tayloe will take to travel 100 miles if he travels 35 miles every 2 days is 40/7 or 5 5/7 in fraction form.
A fraction is a representation of a part of the whole.
Written as a/b, read as "a by b", it functions as a number of parts of a total of b number of parts.
In the question, we are given that Tayloe travels 35 miles every 2 days to work.
Therefore, daily traveling done by Tayloe can be shown as a fraction, 35/2 miles.
The total traveling given to us is 100 miles.
Thus, the number of days Tayloe will take to travel 100 miles can be shown in fractional form as 100/(35/2) = (100*2)/35 = 40/7 or 5 5/7.

What information can be used to compare linear relationships? Explain why
Answer:
A linear relationship can be represented by a straight-line graph and by an equation of the form y=mx+b. In the equation, m is the slope of the line, and b is the y-intercept. Used to track changes over short and long periods of time. When smaller changes exist, this graph is better to use than bar graphs.
The angle by which turns clockwise about point b to coincide with is 63.9 degrees. if from point b, a point e is drawn directly opposite point c so that b, e, and c are on the same straight line, the angle by which turns counterclockwise to coincide with is 243.9 degrees.
AB turns clockwise to coincide with BC.
To find the angle by which turns counterclockwise to coincide with is 243.9 degrees:
An angle -
An angle is a figure in Euclidean geometry created by two rays, called the sides of the angle, that share a common termination, called the vertex of the angle. Angles formed by two rays are located in the plane containing the rays. Angles are also generated when two planes intersect. These are known as dihedral angles.So,

= 33.3° + 30.6°
= 63.9°
b) If E is drawn directly opposite C.
EBC is a straight line, so the sum of angles =180°
ABE + ABD + DBC = 180°
ABE + 33.3° + 30.6° = 180°
ABE + 63.9° = 180°
ABE = 180 - 63.1
ABE = 116.9
Therefore, AB turns clockwise to coincide with BC.

Let P(x) = 3x³-ax+b. If P(1) = P(-1) and P(2)=16, find the values of a and b
P(1) = P(-1)
P(1) = 3 - a + b
P(-1) = -3 + a + b
-> 3 - a + b = -3 + a + b
-> 3 - a + b + 3 - a - b = 0
-> 6 - 2a = 0
-> a = 3.
P(2) = 24 - 2a + b -> 24 - (2a - b) = 16 -> 2a - b = 8
-> 6 - b = 8
b = -2.
So, a = 3 and b = -2
Recheck : P(1) = 3 - 3 + (-2) = -2
P(-1) = -3 + 3 + (-2) = -2 => P(1) = P(-1) (true)
P(2) = 24 - 6 + (-2) = 16.

Answer:
third option listed
Step-by-step explanation:
We know that Johnny does not ever stay/wait at the same distance from the wall, as that would look like a flat line (the y-value / distance would be unchanging, it would be constant)
So, the only possibly correct option is C, because all other options describe him pausing
But why is it not A? We know that at "0" y we are at the gym wall, and that each point is a point that he turns around and runs the opposite way. He first runs away, back, away, back, away, back--which we know because of the direction of the line over time. We also can tell that each period of "away, back" is the same distance, and it takes the same time to travel that distance, by looking at the length of each line.
hope this helps!! have a lovely day :)
Answer:
the 3rd answer option
Step-by-step explanation:
as we can see, time is on the x-axis.
(0, 0) means start of the action (0 seconds) with 0 distance to the gym wall.
then we see that for 2 seconds Johnny increases the distance to the gym wall up to 3 units (the line goes to (2, 3)).
then we see that for the next 2 seconds he returns to the gym wall (0 distance).
then for 3 seconds he increases the distance to the gym wall to 5 units. the line goes to (7, 5). and then for the next 3 seconds he returns to the gym wall (0 distance). then for 4 seconds he increases the distance to the gym wall to 7 units. the line goes to (14, 7). abd then for the next 4 seconds he returns to the gym wall (0 distance).

The bank manages IRAs (traditional and Roth), which are retirement funds that invest in different stocks and bonds to earn interest. Traditional IRAs offer tax-deferred growth. An individual doesn't have to pay taxes on earnings until he or she is ready to make withdrawals (i.e., after retirement). Roth IRAs offer tax-deferred growth until retirement and tax-free withdrawals while in retirement. The bank offers merchant services for small businesses. The bank processes payments via credit cards, debit cards, checks, gift cards, and international payments. Wells Fargo also gives small businesses options on how to accept customer payments: online shopping carts, mobile apps, and onsite payment processing equipment.The bank offers affordable student loans to cover the cost of tuition, books, computers, and housing. Students are not required to make loan payments until six months after leaving school. The bank offers two types of interest rates on student loans: variable and fixed. Variable interest rates range from 3% to 8% and fixed rates range from 5% to 10%.

Using the graph below, which of the following equations represents the line that is parallel to line FG and passes through the (8,−3) point?
my only answers can be the ones in the attached image (just had a random one ticked)
Answer:
the second option: [tex]7x+4y=44[/tex]
Step-by-step explanation:
So when a line is parallel, it means that it has the same slope and a different y-intercept, it's important that there is a different y-intercept, otherwise it would be the same line, and the "two lines" would intersect at infinite points.
Anyways by looking at the graph you have two points (-8, 5) and (-4, -2). So the run in this case was 4 and the rise was -7. This is a slope of -7/4. So we have the equation: [tex]y=-\frac{7}{4}x+b \text{ where b}\ne-9}[/tex]. Since it passes through the point (8, -3) we can plug that in as (x, y) to solve for b (the y-intercept)
Plug in (8, -3) as (x, y)
[tex]-3=-\frac{7}{4}(8)+b[/tex]
Multiply the -7/4 and 8
[tex]-3 = -14+b[/tex]
add 4 to both sides
[tex]11 = b[/tex]
So this gives us the equation:
[tex]y=-\frac{7}{4}x+11[/tex]
Since it's asking for it in standard form you move the 7/4 x to the other side
Add 7/4x to both sides
[tex]\frac{7}{4}x+y=11[/tex]
Multiply both sides by 4 to cancel out the fraction
[tex]7x+4y=44[/tex]

Total number of legs --> 8 + 6 = 14 ( 1 set )
Number of sets that can fit --> 76 ÷ 14 = 5 R 6
Since each set has a beetle and a spider,
Number of spider -->5 × 1 = 5
Since there are additional 6 legs:
Number of beetles --> ( 5 × 1 )+ 1 = 6
Mary has $6$ identical basil plants, and three different window sills she can put them on. How many ways are there for Mary to put the plants on the window sills
There are 28 ways for Mary to put the plants on the sills.
We can use the Binomial Theorem to solve this problem.
We have 6 plants and 3 sills, so we have6 + 3 − 1 = 8 total objects.

The coefficient [tex]x^{6} y^{2}[/tex] will be the number of ways for Mary to put the plants on the sills. We can expand [tex](x + y)^{8}[/tex]

Since we are only interested in the coefficient of [tex]x^{6} y^{2}[/tex] , we can ignore all terms that do not have [tex]x^{6}[/tex] and [tex]y^{2}[/tex].
Therefore, we are left with [tex](\left\ {{8}\atop {2}} \right. )x^{6}y^{2}[/tex]
[tex](\left\ {{8}\atop {2}} \right. )=\frac{8!}{2!(8-2)!} =\frac{8!}{2!6!} =\frac{8*7*6!}{2!6!} =28\\[/tex]

Help me. I'm stuck on this question thank u
Answer: 18
Step-by-step explanation:
(3+6)/2*4
Answer:
18 square feet.
Step-by-step explanation:
Area of trapezoid:a = 6 ft
b = 3 ft
h = 4 ft
a & b are the length of the parallel lines. h is the height between the parallel lines.
[tex]\sf \boxed{\text{\bf Area of trapezoid =$ \dfrac{(a+b)*h}{2}$}}[/tex]
[tex]\sf =\dfrac{(6+3)*4}{2}\\\\=\dfrac{9*4}{2}\\\\= 9 * 2\\\\= 18 \ ft^2[/tex]

An observatory is 150 feet high. when a person is standing in the observatory looking at an island, the angle of depression is . what is the approximate horizontal distance from the observatory to the island?
Using Trigonometry, the approximate distance from the observatory to the island is evaluated to be 322 feet.
Given Information
It is given that,
The height of the observatory = 150 feet
The angle of depression from the top of the observatory = 25°
We can calculate the horizontal distance of the observatory from the island using Trigonometry
What is Trigonometry?
The area of mathematics known as Trigonometry is concerned with certain functions of angles and how to use them in computations. There are six popular Trigonometric functions for an angle. Sine (sin), cosine (cos), tangent (tan), cotangent (cot), secant (sec), and cosecant (csc) are their respective names and acronyms.
Calculating the Horizontal Distance Using Trigonometry
As per the rules of the Trigonometry,
[tex]tan \alpha = \frac{Perpendicular/ Opposite Side}{Base}[/tex]
Here,
[tex]\alpha[/tex] = 25°
Perpendicular = 150 ft.
Base = Horizontal Distance
Thus, [tex]tan 25 =\frac{150}{Horizontal Distance}[/tex]
∴ x ≈ 322 ft.
