Option 3 is correct
tex]\frac{1yd}{36 in}=\frac{7yd}{252 in}[/tex]
Step-by-step explanation:
1.[tex]\frac{1 in}{2.54 cm}=\frac{7 in}{17.68 cm}[/tex]
1 in=2.54 cm
[tex]7 in=2.54\times 7=17.78 cm[/tex]
[tex]\frac{1 in}{2.54 cm}=\frac{1 in}{1 in}=1[/tex]
[tex]\frac{1 in}{2.54 cm}\neq \frac{7 in}{17.68 cm}[/tex]
Hence, it is not correct.
2.[tex]\frac{1 ft}{12 in}=\frac{7ft}{74 in}[/tex]
1 foot=1 2in
[tex] 7ft=7\times 12=84 foot[/tex]
[tex]\frac{1 ft}{12 in}=1[/tex]
[tex]\frac{7ft}{74 in}\neq 1[/tex]
[tex]\implies \frac{1 ft}{12 in}\neq \frac{7ft}{74 in}[/tex]
Hence, it is not correct.
3.[tex]\frac{1yd}{36 in}=\frac{7yd}{252 in}[/tex]
1 yd=36 in
[tex]\frac{1yd}{36 in}=\frac{36}{36}=1[/tex]
[tex]7yd=7\times 36=252 in[/tex]
[tex]\frac{7yd}{252 in}=\frac{252 in}{252 in}=1[/tex]
[tex]\implies \frac{1yd}{36 in}=\frac{7yd}{252 in}[/tex]
Hence, it is correct.
4.[tex]\frac{1 m}{3.28ft}=\frac{7m}{22.86ft}[/tex]
1 m=3.28 ft
[tex]\frac{1 m}{3.28ft}=\frac{3.28}{3.28}=1[/tex]
[tex]7m=7\times 3.28=22.96 ft[/tex]
[tex]\frac{7m}{22.86ft}\neq 1[/tex]
[tex]\frac{1 m}{3.28ft}\neq \frac{7m}{22.86ft}[/tex]
Hence, option is not correct.

Answers
Answer:
6 meters and 3 meters are the dimensions of the vegetable patch.
Step-by-step explanation:
Keep in mind the formulas for perimeter and area of a rectangle are:
A - lw
P - 2 (l + w)
List the factors of 18:
1, 2, 3, 6, 9, 18
POSSIBLE DIMENSIONS of the vegetable patch:
1 meter and 18 meters
Area - 18 m^2
Perimeter - 38 meters
2 meters and 9 meters
Area - 18 m^2
Perimeter - 22 meters
3 meters and 6 meters
Area - 18 m^2

Answers
Answer:
-15
Step-by-step explanation:
df(x, y) / dy = lim (f(x, y+h) - f(x, y)) / h =
lim (e^x^2 - 15y - 15h - e^x^2 ‐ 15y) / h = lim -15h / h = -15
so, the first derivative of f(x,y) by y is simply a constant : -15
fy (x, y) = -15 for any and every values of x and y.
the fast track would be derivative calculation :
the derivative by y makes x a constant. and every constant is eliminated for derivation.
so, e^x^2 goes away (= 0 in the derivative).
that leaves -15y = -15×y¹. its derivative simply is
1×-15×y⁰ = -15

Answer:
turning points
Step-by-step explanation:
The number of turning points is the number of real zeros in the derivative polynomial. As you know, the number of real zeros of a polynomial is at most the polynomial degree.
The degree of the derivative is always 1 less than the degree of the polynomial. So, a polynomial of degree n will have at most (n-1) turning points.

Answer:
178.3 ft
Step-by-step explanation:
Since you have the angle 27 and the side length of 350 you can set up a proportion that is Tan(27)=y/350. You can solve from this to 350*tan(27)=y and then simplify to 178.3.
Answer:
y =178.3
Step-by-step explanation:
Since this is a right triangle, we can use trig functions
tan theta = opp /adj
tan 27 = y/350
350 tan 27 = y
178.3339073=y
Round to the nearest tenth
y =178.3

Add this to the original price
2+1 =3
The store sells the cereal for $3.00
Answer:
$3
Step-by-step explanation:
The grocery store pays $2.00 for each box of cereal bought.
First, find 50% of the cost of each box:
2.00 x 0.50 = 1.00
Next, add the additional amount to the starting price:
2.00 + 1.00 = $3.00
$3.00 is your answer.

Select two choices that are true about the function f(x)=23x+14/x
Answers
Answer:
There is an asymptote at x = 0
There is an asymptote at y = 23
Step-by-step explanation:
Given the function:
(23x+14)/x
Vertical asymptote is gotten by equating the denominator to zero
Since the denominator is x, hence the vertical asymptote is at x = 0. This shows that there is an asymptote at x = 0
Also for the horizontal asymptote, we will take the ratio of the coefficient of the variables in the numerator and denominator
Coefficient of x at the numerator = 23
Coefficient of x at the denominator = 1
Ratio = 23/1 = 23
This means that there is an asymptote at y = 23

Hi hopefully this helps you!
Step-by-step explanation:
To find the area of a circle you can use the formula A = πr^2
The radius of a circle is just the diameter divided by 2. In this case we know the diameter is 3, so the radius is 1.5
A = π(1.5)^2
= 7.07
Because this is a semicircle, divide this area by 2
= 3.53429 in^2
Add up the area of this semi circle with the area of the rectangle
A = (3.53429) + (3x4)
= 15.53429 in^2
To find the circumference/ perimeter of a circle use this formula C = 2πR
C = 2π(1.5)
= 9.42478 inches
Again because this is a semicircle, divide by 2
= 9.42478 / 2
= 4.71239 inches
To find the perimeter of this entire shape add up the circumference of the semicircle and the rectangle's sides and bottom
P = 4.71239 + 4 + 4 + 3
= 15.71239 inches
So the final answer would be
A = 15.53 squared inches
P = 15.71 inches
