Answer:
Solution given;
l=4.5ft
b=2ft
h=2ft
now
volume=l*b*h=4.5*2*2=18ft³
is a required volume.
Now
total surface area =2(lb+lh+bh)
=2(4.5*2+4.5*2+2*2)=44ft²
is a total surface area.
Answer:
Surface area: 44 ft² or 44 square feet
Volume: 18 ft³ or 18 cubic feet
Step-by-step explanation:
Volume:
V = whl
2 · 2 · 4.5
18
Surface area:
A = 2(wl + hl + hw)
2 · (2 · 4.5 + 2 · 4.5 + 2 · 2)
44

Answers
Answer:
5 3/4 hours remaining to meet his goal
Step-by-step explanation:
miles required to meet his goal = 13 1/2 miles
Miles ran on monday =3 1/2
Miles ran on Tuesday =4 1/4
Miles remaining to reach his goal =Total miles required - Miles ran on Monday and Tuesday
13 1/2 - ( 31/2 + 4 1/4 )

Answers
Explanation:
Basically you just change the letter for the number since R equals 6 then in the equation it would be 6 instead of R. Then for S, S would equal 1÷4 which equals 0.25. Then you plug in the numbers into your equation so look something like this 6 x 0.25 + 14(0.25) and all that together equals 5.

a. An equation for the graph is y=2x^2-9x+7
b. the function has two roots
c. The solutions of the related quadratic equation are -1.5 and -3
d. The related quadratic equation has two solutions
Answers
Step-by-step explanation:
The solutions of the related quadratic equation are -1.5 and -3
To summarize, the true statements are:
(b) The function has two roots.
(d) The related quadratic equation has two solutions.
What is a Quadratic equation?ax²+bx+c=0, with a not equal to 0 is a quadratic equation, which is a second-order polynomial equation in a single variable. It has at least one solution because it is a second-order polynomial equation, which is guaranteed by the algebraic fundamental theorem. The answer could be simple or complicated.
To determine which statements about the quadratic function that passes through (1,0) and (3.5,0) are true, we need to use the fact that the roots (or x-intercepts) of a quadratic function can be found by solving the related quadratic equation, which is obtained by setting the function equal to zero.
Let's start with a statement (a). Plugging in the two points given into the equation y = 2x^2 - 9x + 7, we get:
At x = 1, y = 2(1)^2 - 9(1) + 7 = 0
At x = 3.5, y = 2(3.5)^2 - 9(3.5) + 7 = 0
This confirms that points (1,0) and (3.5,0) are indeed on the graph of the function, but it doesn't tell us whether this is the only function that passes through those points. So statement (a) alone is not sufficient to determine the true statements.
Next, let's consider statement (b). Since the graph passes through (1,0) and (3.5,0), we know that it must cross the x-axis at those two points. Therefore, the function has two roots or x-intercepts. Statement (b) is true.
Moving on to statement (c), we need to find the solutions of the related quadratic equation. Setting y = 2x² - 9x + 7 equal to zero, we get:
2x² - 9x + 7 = 0
Using the quadratic formula, we find that the solutions are:
x = (9 ± √(9² - 4(2)(7))) / (2(2)) ≈ 2.5 and ≈ 1.75
Therefore, statement (c) is false.
Finally, statement (d) asks whether the related quadratic equation has two solutions. We just found that it has two solutions, so statements (b) and (d) are true.

____________________Solution :-Given Information :- Base of Triangle = 12 ftBase² = 12² = 144 ftAltitude of Triangle = 8 ftAltitude² = 8² = 64 ftTo Find :- Hypotenuse of Triangle Formula Used :- Pythagoras Theorem ↓Hypotenuse² = Base² + Altitude²Calculation :-Here, we will substitute the given values in the formula,
⇒ Hypotenuse² = ( 144 + 64 ) ft
⇒ Hypotenuse² = 208 ft
Now transposing the square to Right Hand Side, We get,

Area of the composite figure = Area of ΔABH + Area of BCGH + Area of ΔDEF
Area of ΔABH = [tex]\frac{1}{2}(\text{Base})(\text{Height})[/tex]
= [tex]\frac{1}{2}(6)(8-5)[/tex]
= 9 in²
Area of the trapezoid = [tex]\frac{1}{2}(CG+BH)(\text{Distance between these lines})[/tex]
= [tex]\frac{1}{2}(6+4)(5)[/tex]
= 25 in²
Area of ΔDEF = [tex]\frac{1}{2}(8)(6)[/tex]

Answers
4x+3y=1 2x+5y=11
We'll need to use system of equations for this one.
4x+3y=1
3y=1-4x
y=-4/3x+1/3
2x+5y=1
5y=1-2x
y=-2x/5+1/5
Set these two equations equal to each other and solve for x.
-2x/5+1/5=-4/3x+1/3
x=1/7
Then plug x in to solve for y.
y=-2(1/7)/5+1/5
y=1/7
Daija is looking to fertilize her 24,000 square foot lawn. Super Lawn fertilizer costs $18.49 and covers 6,000 square feet. Quick Fertilizer costs $23.99 and covers 8,000 square feet.
Answers
Answer:
A.) Cheaper Fertilizer is Quick Fertilizer
B.) The cheaper fertilizer now cost $ 61
Step-by-step explanation:
The exact question is as follows :
Given - Daija is looking to fertilize her 24,000 square foot lawn. Super Lawn fertilizer costs $18.49 and covers 6,000 square feet. Quick Fertilizer costs $23.99 and covers 8,000 square feet.
To find - A.) Which fertilizer would be cheaper for Daija to purchase to fertilize her entire lawn?-Show your work or explain your answer.
B.) Daija has a 15% off coupon on the cheaper fertilizer. Excluding sales tax, what is the new cost of the fertilizer? Round to the nearest cent.
Proof -
A.)
Given that,
Total lawn that have to be fertilize = 24,000
Now,
Super Lawn fertilizer costs $18.49 and covers 6,000 square feet.
i.e.
6000 square feet = $ 18.49
⇒4×6000 square feet = $ 4×18.49
⇒24000 square feet = $ 73.96
∴ we get
Super Lawn costs $ 73.96
Now,
Quick Fertilizer costs $23.99 and covers 8,000 square feet.
i.e.
8000 square feet = $ 23.99
⇒3×8000 square feet = $ 3×23.99
⇒24000 square feet = $ 71.97
∴ we get
Quick Fertilizer costs $ 71.97
As we get
Super Lawn costs $ 73.96
Quick Fertilizer costs $ 71.97
As $ 71.97 < $ 73.96
So,
Cheaper Fertilizer is Quick Fertilizer
B.)
As we get from part a) that
Quick Fertilizer is cheaper and it costs $ 71.97
So,
15% of 71.97 = 10.7955
∴ we get
Now,
Quick fertilizer cost = $ 71.97 - 10.7955
= $ 61.1745 ≈ $ 61
So,
After applying the 15% coupon,
The cheaper fertilizer now cost $ 61
