Higher Order Thinking A farmer grows
128 red tomato
plants and 102 yellow tomato plants. Each plant produces
about 32 tomatoes. The farmer plans to
sell each tomato
for a $2. Explain how to find a reasonable estimate for the
total amount of money the farmer will earn if she sells all
of the tomatoes.
Answer: 14720 dollars, or $14720
Step-by-step explanation:
128 red tomato plants plus 102 yellow tomato plants = 230 tomato plants in total.
230 plants with 32 tomatoes each = 7360 tomatoes in all
7360 x 2 dollars = 14720 dollars

You buy 50 feet of fence to place around a rectangular yard. If the length of the yard is 13 feet, what is the constraint for the width of the yard? Let w represent width *
Step-by-step explanation:
a fence represents the circumference, the perimeter of the lot or yard.
remember, a rectangle has 2 parallel sides called the length, and 2 parallel sides called the width (altogether 4 sides).
therefore
perimeter = 2×length + 2×width
or with short variables
p = 2×l + 2×w
so, now we have 50 ft of fence available for the perimeter. and the length l = 13 ft.
since we have 2 lengths in the perimeter, these 13 ft are twice (2×13 = 26 ft) in the perimeter.
now, how much fence do we have left for the width ?
well, 50 - 26 = 24 ft
and again, this is the size of 2 sides (2×width) :
p = 2×l + 2×w
50 = 2×13 + 2×w = 26 + 2×w
2×w = 24
w = 12 ft
so, the width of the yard must not be bigger than 12 ft.
2r=5s/2-s/4 (solve for s)
Answer:
s=8r/9
Step-by-step explanation:
2r=5s/2-s/4 multiply both sides by 4
8r=10s-s (5s times 4 = 20s and 20s/2=10s) combine like terms
8r=9s divide by 9 to isolate s
8r/9=s

margo is repaying a loan from her parents. she has already paid $315 and still owes them $1245. write an equation to find the original amount a of the loan
Answer:
n-315=1245
Step-by-step explanation:
n stands for the original amount of the loan. Margo has paid $315, so the original number minus what Margo has paid, and the equality is the amount that Margo still owes.

Find the area and perimeter of the shape
help me with this pelases
Answer:
32 square units
Step-by-step explanation:
You can split this shape into four different shapes:
2 unit by 2 unit triangle
2 unit by 2 unit square
2 unit by 6 unit triangle
To find the length of the big triangle, add the lengths of the small triangle,the square,and the bigger leg of the other triangle:
2 + 2 + 6 = 10
10 unit by 4 unit triangle
Then solve all these areas:
( 2 x 2 ) / 2 = 4 / 2 = 2
2 x 2 = 4
( 2 x 6 ) / 2 = 12 / 2 = 6
( 10 x 4 ) / 2 = 40 / 2 = 20
Then add all these areas together to get the total area of the composite shape:
2 + 4 + 6 + 20 = 32
Maths question, someone pls help me solve it
60 POINTS PLS HELP WILL MARK BRAINLIEST EXPLAIN TOO PLS
Step-by-step explanation:
we need to find the slope of each line.
the slope is the ratio y/x indicating how many units y changes, when x changes a certain amount of units.
parallel lines have the same slope.
for a perpendicular line x and y in the slope ratio are put upside down, and the sign is flipped (+ to - and vice versa).
a.
2x - 8y = -24
2x + 24 = 8y
y = 2/8 x + 24/8 = 1/4 x + 3
the slope is 1/4 (always the factor of x).
4x + y = -2
y = -4x - 2
the slope is -4 = -4/1.
this line is therefore perpendicular to the first line.
x - 4y = 4
x - 4 = 4y
y = 1/4 x - 4/4 = 1/4 x - 1
the slope is 1/4.
this line is therefore parallel to the first line.
b.
3x - 9y = 9
9y = 3x - 9
y = 3/9 x - 9/9 = 1/3 x - 1
the slope is 1/3
3y = x + 12
y = 1/3 x + 4
the slope is 1/3.
this line is therefore parallel to the first line.
2x - 6y = 12
6y = 2x - 12
y = 2/6 x - 12/6 = 1/3 x - 2
the slope is 1/3.
this line is therefore parallel to the first line.
3y=9-12x I need the slope for this equation and the steps
Answer:
slope = -4
Step-by-step explanation:
3y = 9 - 12x
Rearrange the right-hand side:
3y = - 12x + 9
Next, Divide both sides by 3 to isolate y:
[tex]\frac{3y}{3} = \frac{-12x + 9}{3}[/tex]
y = -4x +3 this is the slope-intercept form where the slope, m = -4, and the y-intercept, b = 3.
Therefore, the slope = -4.

I need help. I’m a little bit confused
Answer: 65 degrees
Explanation:
The adjacent angle directly above angle 8 is congruent to the 115 degree angle (due to the corresponding angles theorem). This only works because p || q and q || r, so by the transitive property of parallel lines, we know that p || r.
Since the 115 degree angle and angle 8 pair up to form a straight line, we know that the two angles must add to 180 degrees
115+(angle 8) = 180
angle 8 = 180 - 115
angle 8 = 65 degrees
Answer:
[tex]m[/tex]∠8 = 65°
Step-by-step explanation:
The other side (angle) of 115 is [tex]n[/tex] and [tex]n =[/tex] ∠8
To find [tex]n[/tex] you need to subtract 180 - 115 giving you 65, and since n is angle 8, angle 8 is also 65 since the angles have a state of congruence...
e^3x.cos4x.sin2x hii please solv this you have to differentiate
Answer:
[tex]y = e^{3x}.cos4x.sin2x[/tex]
[tex]=> y' =- 3e^{3x}.4sin4x.2cos2x=-24.e^{3x}.sin4x.cos2x[/tex]
[tex]dy=y'.dx => dy = -24e^{3x}.sin4x.cos2x.dx[/tex]
Step-by-step explanation:
The function [tex]e^3^x[/tex].cos4x.sin2x on differentiating gives the solution as 2[tex]e^3^x[/tex]cos2x.cos4x - 4[tex]e^3^x[/tex]sin2x.sin4x + 3[tex]e^3^x[/tex]cos4x.sin2x.
What is Product rule in Differentiation?Product rule in differentiation states that, for two functions f(x) and g(x),
[tex]\frac{d}{dx}[/tex] [f(x).g(x)] = f(x) . [tex]\frac{d}{dx}[/tex][g(x)] + g(x) . [tex]\frac{d}{dx}[/tex][f(x)]
The question is to differentiate y = [tex]e^3^x[/tex].cos4x.sin2x
We have three functions here.
Let u = [tex]e^3^x[/tex] and v = cos4x.sin2x
[tex]\frac{d}{dx}[/tex] [u . v] = u [tex]\frac{d}{dx}[/tex][v] + v [tex]\frac{d}{dx}[/tex][u]
= [tex]e^3^x[/tex] [tex]\frac{d}{dx}[/tex] [cos4x.sin2x] + cos4x.sin2x [tex]\frac{d}{dx}[/tex] [[tex]e^3^x[/tex] ]
= [tex]e^3^x[/tex] [tex]\frac{d}{dx}[/tex] [cos4x.sin2x] + cos4x.sin2x (3[tex]e^3^x[/tex])
[tex]\frac{d}{dx}[/tex] [u . v] = [tex]e^3^x[/tex] [tex]\frac{d}{dx}[/tex] [cos4x.sin2x] + 3[tex]e^3^x[/tex]cos4x.sin2x
Let the above equation be equation E.
Again apply the product rule for [tex]\frac{d}{dx}[/tex] [cos4x.sin2x].
Let u' = cos4x and v' = sin2x
[tex]\frac{d}{dx}[/tex] [u'. v'] = u' [tex]\frac{d}{dx}[/tex][v'] + v' [tex]\frac{d}{dx}[/tex][u']
= cos4x [tex]\frac{d}{dx}[/tex][sin2x] + sin2x [tex]\frac{d}{dx}[/tex][cos4x]
= cos4x [2cos2x] + sin2x [-4sin4x]
= 2cos2x.cos4x - 4sin2x.sin4x
Substituting this is equation E, we get,
[tex]\frac{d}{dx}[/tex] [u . v] = [tex]e^3^x[/tex] [2cos2x.cos4x - 4sin2x.sin4x] + 3[tex]e^3^x[/tex]cos4x.sin2x
= 2[tex]e^3^x[/tex]cos2x.cos4x - 4[tex]e^3^x[/tex]sin2x.sin4x + 3[tex]e^3^x[/tex]cos4x.sin2x
Hence the function [tex]e^3^x[/tex].cos4x.sin2x on differentiating gives 2[tex]e^3^x[/tex]cos2x.cos4x - 4[tex]e^3^x[/tex]sin2x.sin4x + 3[tex]e^3^x[/tex]cos4x.sin2x.
