Consider that each unit on the grid represents 4ft. The figure consists of 2 identical equilateral triangles and 3 identical rectangles. Calculating the area of one of each kind of shape,
[tex]\begin{gathered} A_{triangle}=\frac{1}{2}b*h=\frac{1}{2}*4*4=\frac{16}{2}=8 \\ A_{rectangle}=4*4(2)=4*8=32 \end{gathered}[/tex]Therefore, the area of a single triangle is 8in^2, while the area of a rectangle is 48in^2. Calculate the total area as shown below
[tex]A_{total}=2*8+4*32=16+128=144[/tex]The area of a sheet of plywood is

m = slopec = interceptThe slope is the gradient which is the ratio of the difference in the y direction to the difference in x direction.
given that the equation of the line is x + 3y = 7
rewriting the equation gives
y = -x/3 + 7/3
hence the slope is -1/3, and this is equated with the formula for slope

substituting the values for points (-2,5) and cross multiplying gives

y - 5 = - (x + 2 ) /3
y - 5 = -x/3 - 2/3
y = -x/3 - 2/3 + 5
y = -x/3 + 13/3
Rewriting the equation of the line in standard form is done as follows
y = -x/3 + 13/3

the parts can be found by looking for the "to" as indicated bold in the question
the first part of the ratio it asks is the "time spent studying in math" in hours which is 6.5

What is a ratio?
We use ratios to compare two numeric quantities or quantities with the same units
Basically a ratio of one quantity x to another quantity y can be expressed in the following ways, all read as the ratio of x to y
x/ y
x to y
x : y
The most useful way of representing a ratio is by using the fractional form because it can be used in determining other quantities
In this problem you spend 6.5 hours/week studying for math and 1.5 hours/week studying for English
Since both units are the same (hours/week) we can compute the ratio as
[tex]{\dfrac{\text{Number of hours studying math}}{\text{Number of hours studying English}}\\\\= \dfrac{6.5}{1.5}\\\\[/tex]
We can simply this fraction as follows
Multiply both numerator and denominator by 10
[tex]= \dfrac{65}{15}\\\\[/tex]
Divide both sides by 5
[tex]\dfrac{65 \div 5}{15 \div 5}\\\\= \boxed{\bold{\dfrac{13}{3}\\\\}}[/tex]
This is the same as 13:3 or 13 to 3
(Be careful what is the numerator and what is the denominator.

Each kick must be taken by a different player
Now, to find the number of ways that 5 players can be selected from the 11 eligible players, we will use combination to get;

It is given that,
If a dragon can eat an entire cow weighing 500 kilograms in 12 seconds,
500 kilograms = 12 seconds
By unitary method
1 kilogram = 12 / 500
1 kilogram = 0.024 second
For 90 kilograms
90 kilogram=90 × 0.024 second

You want to fence off a rectangular area of yard using the back side of your house as one of the sides. You have a total of 150 yards of fence. If the area of the fenced in portion comes to 2,800 square yards, what are the dimensions of the fenced-in area? Show all work for full credit.
Answers
The dimensions of the fenced-in area is
either length = 35 yards and width = 80 yards ,
or length = 40 yards and width = 70 yards .
In the question ,
it is given that
the total length of the fence = 150 yards
let L be the length of the area to be fenced
let B be the width of the house
Given that one side of the area is fenced using the back side of the house
So, the perimeter of the area to be fenced is 2L+B
equating both the perimeter we get
2L+B=150
B=150-2L ....(i)
Given the area fenced-in portion = 2800 yards
also the fenced-in portion area = L×B
hence
L*B=2800
Substituting the values of B from equation(i) , we get
L*(150-2L)=2800
150L - 2L² = 2800
2L² - 150L + 2800 = 0
simplifying further , we get
L² - 75L + 1400 = 0
L² -40L -35L +1400 = 0
L(L-40) -35(L-40) = 0
(L-35)(L-40) = 0
So , L = 35 yards or L = 40 yards
Using L = 35 yards , we get B = 150-2(35) = 80 yards
and using L =40 yards , we get B = 150-2(40) = 70 yards .
Therefore , The dimensions of the fenced-in area is
either length = 35 yards and width = 80 yards ,
or length = 40 yards and width = 70 yards .

suppose you are35 years old and would like to retire at age65 . Furthermore, you would like to have a retirement fund from which you can draw an income of $150000 per yearforever! How much would you need to deposit each month to do this? Assume a constant APR of8 % and that the compounding and payment periods are the same.
Answers
Answer:
$1258.09
Step-by-step explanation:
You want the monthly annuity payment that will let you withdraw $150,000 per year forever from an account earning 8% after 30 years.
Account balanceIn order to withdraw an amount "forever," the withdrawal amount must be equal to the interest earned by the account.
I = Prt
150,000 = P(0.08)(1)
P = 150,000/0.08 = 1,875,000
Annuity paymentThe value of an ordinary annuity is given by the formula ...
A = P(12/r)((1 +r/12)^(12t) -1) . . . . . where P is the monthly payment, and r is the annual interest rate earned over a period of t years.
Using the values we know, we can find P:
1875000 = P(12/0.08)((1 +0.08/12)^(12·30) -1) = 1490.359449P
P ≈ 1258.09
You would need to deposit $1258.09 each month.
