The area of a rectangular field is 7371 m2. If the length of the field is 91 meters, what is its width?
Answer:
81 m
Step-by-step explanation:
From the question given above, the following data were obtained:
Area (A) = 7371 m²
Length (L) = 91 m
Width (W) =?
Area of a rectangle is given by the following equation:
Area = Length × Width
A = L × W
With the above formula, we can obtain the width of the rectangular field as follow:
Area (A) = 7371 m²
Length (L) = 91 m
Width (W) =?
A = L × W
7371 = 91 × W
Divide both side by 91
W = 7371 / 91
W = 81 m
Thus, width of the rectangular field is 81 m
The quotient property of radicals requires the indices of the radicals to be the same. Does this mean that it is not possible to write 4Vy^3/Vy as a single radical? Explain.
Answer:
The radicals are the power of the same base so they can be written using rational exponents. Simplified the quotient of the exponential expression by getting a common denominator and subtracting exponents. The simplified expression is the 4th root of y

Evaluate. 2.2^3 . 2^-5 .2^-1
A. -4
B, -8
C. 1/4
D. 1/8
Answer:
Step-by-step explanation:
2^3 . 2^- 5 . 2^- 1
= 2^( 3 - 5 - 1 )
= 2^( 3 - 6 )
= 2^- 3
= 1 / 2^3
= 1 / 8
If
2 . 2^3 . 2^- 5 . 2^- 1
= 2^1 . 2^3 . 2^- 5 . 2^- 1
= 2^( 3 - 5 - 1 + 1 )
= 2^( 3 - 5 )
= 2^- 2
= 1 / 2^2
= 1 / 4

Find the area of this shape *
Answer:
134.1 ft²
Step-by-step explanation:
Fine the area of the square first, then subtract the area of the circle to find the area of the shaded part.
The area of the square
= 25²
= 625 ft²
The radius of the circle
= 25 ÷ 2
= 12.5 ft
The area of the circle
= π × 12.5²
= 490.87385...
= 490.9 ft² (rounded up to the nearest tenth)
The area of the shaded part
= 625 - 490.9
= 134.1 ft²

Find the value of x and y that will make each quadrilateral a parallelogram.
Answer:
6
Step-by-step explanation:
Answer:
x = 15, y = 7
Step-by-step explanation:
opposite angles are congruent in a parallelogram:
=> 3x + 4 = 7y
=> 3x - 7y = -4
the same-side interior angles of a parallelogram are supplementary angles, which means they sum to 180°:
=> 8x + 11 + 7y = 180
=> 8x + 7y = 169
add the two equation 3x - 7y = -4 and 8x + 7y = 169 to eliminate y and solve for x:
=> 3x - 7y = -4
8x + 7y = 169
+) ___________
11x = 165 => x = 15
plug x = 15 into one of the two equation to solve for y:
=> 3(15) - 7y = -4
=> 45 - 7y = -4
=> 7y = 49
=> y = 7
Trig homework. Find the two missing sides and write your answer as in simplified radical form.
Answer:
u = 8, v = 4[tex]\sqrt{2}[/tex]
Step-by-step explanation:
Using the sine ratio in the right triangle and the exact value
sin45° = [tex]\frac{1}{\sqrt{2} }[/tex] , then
sin45° = [tex]\frac{opposite}{hypotenuse}[/tex] = [tex]\frac{4\sqrt{2} }{u}[/tex] = [tex]\frac{1}{\sqrt{2} }[/tex] ( cross- multiply )
u = 8
The triangle is right isosceles with legs congruent, so
v = 4[tex]\sqrt{2}[/tex]

Step-by-step explanation:
Write a rule to describe the transition of a point from (-3,3) to (-2,2)
In the answers, we see that the rule must be formatted as:
(x,y) ⇾ (x _ 1, y _ 1)
Soo . . we take the first x (-3) and the second x (-2) and try the 2 methods:
-3 - 1 = -4
-3 +1 = -2
So we see that the first one has to + 1
Here's the rule so far.
(x,y) ⇾ (x + 1, y _ 1)
Next, take the first y (3) and the second y (2) and repeat the 2 methods:
3 + 1 = 4
3 - 1 = 2
Here we get that we have to - 1
Therefore, the rule to describe the transition of a point from (-3,3) to (-2,2) is:
(x,y) ⇾ (x + 1, y - 1)
Which is option 4 or D.
Hope this helps you understand a bit better! =)

Jennifer buys a desk on sale for $478.60. If the regular price was $684.00, what is the percentage of discount?
Answer:
30%
Step-by-step explanation:
Find the percent discount by dividing the change in the price by the original price:
(684 - 478.6) / 684
205.4 / 684
= 0.3
So, the percent discount was approximately 30%

Answer:
There are 3,750 sweets in the carton
Step-by-step explanation:
Here, we want to get the total number of sweets
From the question, we have that individual box have 50 sweets
So the number of sweets in the carton have 75 boxes will be the product of the number of sweets and the number of boxes
Mathematically, we have this as;
50 * 75 = 3,750 sweets

Mary made 12 bracelets. 9 of those bracelets are the color blue.
What percent of bracelets are blue?
Answer:
75%
Step-by-step explanation:
We know that Mary made twelve bracelets and also that nine of them are blue, we are then asked to find the percentage of the bracelets that are blue.
To solve, first get a fraction of how many of the bracelets are blue. Since there are twelve in total, 12 will be our denominator, and since 9 are blue, 9 will be our numerator.
[tex]\frac{9}{12}[/tex]
Now to turn this into a percentage, we need to reduce this fraction to the lowest we can. Both numerator and denominator are divisible by 3, so do as followed :
[tex]\frac{9/3}{12/3}[/tex]
[tex]\frac{3}{4}[/tex]
Divide 3 by 4 :
[tex]3/4 = 0.75[/tex]
Multiply 0.75 by 100 to get our percentage :
[tex]0.75 * 100 = 75[/tex]%

Answer:
16
Step-by-step explanation:
Find the area of this parallelogram. Be sure to include the correct unit in your answer.
Opposite sides are equal in length and opposite angles are equal in measure. To find the area of a parallelogram, multiply the base by the height. The formula is: A = B * H where B is the base, H is the height, and * means multiply.
Answer:
A = 126 cm²
Step-by-step explanation:
The area (A) of a parallelogram is calculated as
A = bh ( b is the base and h the perpendicular height )
Here b = 14 and h = 9 , then
A = 14 × 9 = 126 cm²

Find the length of side x in simplest radical form with a rational denominator.
Answer:
x=2√5
Step-by-step explanation:
1st method:
sin(30)=opposite/hypotenuse=√5/x
sin(30)x=√5
x=√5/sin(30)
x=2√5
2nd method:
cos(60)=adjacent/hypotenuse=√5/x
cos(60)x=√5
x=√5/cos(60)
x=2√5
3rd method:
This is a 30-60-90 triangle, so we can multiply the short side, √5, by 2, to get x=2√5
