The value of 'y' for the parallel line drawn by the Amir is 25°.
Describe the term transversal?A transversal would be any line which intersects 2 straight lines at different point in geometry. In geometry, a transversal line connects two lines within the same plane at 2 separate points. Transversals contribute to the parallelism of two or more additional straight lines inside the Euclidean plane.For the given question;
There are two parallel line cut by the transversal drawn by the Amir.
Thus, the relation of the two angles are-
The supplement angle of (4y - 45) is 180 - (4y - 45).
And,
180 - (4y - 45) = y (vertical angles)
Simplify the equation;
180 - 4y + 45 = y
5y = 125
y = 25°
Thus, value of 'y' for the parallel line drawn by the Amir is y = 25°.

Jamir is training for a race and is running laps around a field. If the distance around the field is 450 yards,how many complete laps would he need to do to run at least 4 miles?laps
We have that Jamir is training for a race and is running laps around a field:
• The distance around the field is 450 yards (per lap).
,• He needs to run at least 4 miles.
1. Now we can proceed as follows to find the number of laps Jamir needs to run as follows:
[tex]\begin{gathered} 1\text{ Mile}=1760.0065617yards \\ \\ 4\text{ Miles=}4(1760.0065617yards)=7040.0262468yards \end{gathered}[/tex]Then we have that Jamir needs to run about 7040.0262468 yards.
2. Since the distance around the field is 450 yards (per lap), then we have:
[tex]7040.0262468yards*\frac{1lap}{450yards}=15.6445027707laps[/tex]Therefore, in summary, Jamir needs to run about 15.64 laps to run at least 4 miles (almost 16 laps - if we round the result to the nearest whole number).

Maggie had a number of identical flowers for sale. She sold 70 of them with a 50% loss and sold the rest with a 80% profit. On the whole, Maggie still made a 10% profit. How many flowers did Maggie have at the beginning?
ANSWER:
130 flowers
STEP-BY-STEP EXPLANATION:
Let x be the total number of flowers, we can establish the following equation:
[tex]70\left(-50\%\right)+\left(x-70\right)\left(80\%\right)=x\left(10\%\right)[/tex]We solve for x:
[tex]\begin{gathered} 70\left(-0.5\right)+\left(x-70\right)\left(0.8\right)=x\left(0.1\right) \\ \\ -35+0.8x-56=0.1x \\ \\ 0.8x-0.1x=56+35 \\ \\ 0.7x=91 \\ \\ x=\frac{91}{0.7} \\ \\ x=130 \end{gathered}[/tex]The total number of flowers, that is, the ones it had at the beginning was 130

The school budget allows no more than $360 to be spent on balls and bats.The cost of a ball is $6 and the cost of a bat is $24write the inequality to represent this information
Since the school budget allows no more than $360 to be spent on balls and bats, we have:
[tex]\text{total cost of balls and bats, in dollars }\le360[/tex]Now, let's call x the number of balls and y the number of bats that can be bought.
• The cost to buy x balls, in dollars, is 6x.
• The cost to buy y bats, in dollars, is 24y.
So, the total cost of balls and bats, in dollars, is 6x + 24y.
Now, we can use this expression in the above inequality to obtain the inequality:
[tex]\mathbf{6x+24y\le360}[/tex](F.LE.5) The function f(x) = 7.75x models the amount of money that Jimearns for each hour of work. What does the lack of a constant tell us?A. There is no initial amount of money he gets paid prior to startingB. His hourly wageC. His total amount he gets paid for the dayD. The number of hours Jim has worked
In a linear model:
[tex]f(x)=mx+b[/tex]The coefficient of x, which is m, is the rate of change of the function f with respect to changes in the value of x. In the context of the problem, the coefficient of x tells us the amount of money that Jim earns per hour.
The constant term b is the initial value of the function f when x=0.
Since the given linear model has no constant term, it means that the initial value is 0. In other words, Jim will earn $0 if he works 0 hours.
Therefore, the correct choice is Option A) There is no initial amount of money he gets paid prior to starting.

Problem
You have $20,000 that you want to deposit into a savings account.
You have four options to choose from, Bank A offers 4.25% compounded monthly, (Ex 2) Bank B offers 6% compounded Semi Annually, (Ex 2) Bank C offers a simple interest account with a 5.5% rate, (Chapter 8.3) Bank D offers a rate of 4% compounded continuously. (Ex 3) How much money will you have in each account if you let the money sit for 5 years? Which is the best choice?
Solution
For this case we need to take in count the compound interest formula given by:
[tex]A=P(1+\frac{r}{n})^{nt}[/tex]Where P= 20000, r= interest rate in fraction and n= number of times that the rate is compounded in a year, t= 5 years and A is the future value
And the simple interest formula:
[tex]A=P(1+rt)[/tex]And compound continuosly:
[tex]A=\text{Pe\textasciicircum{}rt}[/tex]Let's calculate the final amount for each case
Bank A
[tex]A=20000(1+\frac{0.0425}{12})^{12\cdot5}=24726.038[/tex]Bank B
[tex]A=20000(1+\frac{0.06}{2})^{2\cdot5}=26878.328[/tex]Bank C
[tex]A=20000(1+0.055\cdot5)=25500[/tex]Bank D
[tex]A=20000e^{0.04\cdot5}=24428.055[/tex]And the best choice for this case seems to be Bank B since we will have more money at the end of the 5 year

It says. Use the graph of f to determine whether the following statement is true or false. The range of f is [-5,1]
The statement is false because the range is [-5, 1)
EXPLANATION
The range of a function is the set of y-values for which the function is defined.
From the graph given the range is:
-5≤ x < 1
This can be represented by interval notation as :
[ - 5, 1)
Therefore, the statement is false because the range is [-5, 1)
