length of a rectangle is 6 feet longer than the width. If the width of the rectangle is w feet long, which of the following expressions represents the
meter of the rectangle?
Answers
Answer:
4w + 12
Step-by-step explanation:
Perimeter of a rectangle = 2(length + width)
Let
Width of the rectangle = w feet
Length of the rectangle = (w + 6) feet
Perimeter of a rectangle = 2(length + width)
= 2{(w+6) + w}
= 2(w + 6 + w)
= 2(2w + 6)
= 4w + 12
Perimeter of a rectangle = (4w + 12) feet

Rebecca saved AED 175.30 in June and AED 132.50 in July. Then she bought a bicycle for AED 195.80. How much of her savings from June and July was left?
Answers
Answer:
her saving that was left from June and July is 112
Step-by-step explanation:
The computation of the saving amount left is shown below;
= Total saving in 2 months - amount spent
= 175.30 + 132.50 - 195.80
= 112
Hence, her saving that was left from June and July is 112
Semi-Trailers are rectangular prisms.
The standard height inside the trailer is
108 inches. If it's 8 ft wide and 20 ft long,
How much toilet paper can it deliver to the
Publix near Ms. Arruda's house?
Hint: Make sure you are using the same units. 1ft = 12in
Answers
Answer:
1440ft^3
Step-by-step explanation:
Volume of a rectangular prism = Length* width * Height
Given
width = 8ft
Length = 20ft
height = 108in
Convert 108 inches to feet
1ft = 12in
x = 108in
x = 108/12
x = 9ft
Get the volume of the prism
Volume = 8 * 20 * 9
Volume = 1440ft^3
Hence the volume of toilet paper it can deliver is 1440ft^3

Step-by-step explanation:

The function N(x) that represents the number of ounces of peanuts in the mixture is N(x)=x.
What is the function?Functions are the fundamental part of the calculus in mathematics. The functions are the special types of relations. A function in math is visualized as a rule, which gives a unique output for every input x.
Given that, Amir has 48 ounces of cashews, walnuts, and pecans.
He adds x ounces of peanuts to create a mixture.
M(x) that represents the number of ounces of all nuts in the mixture.
M(x)=48
N(x) that represents the number of ounces of peanuts in the mixture.
So, N(x)=x
Now, (M/N)(x) = M(x)/N(x)
= 48/x
Therefore, the function N(x) that represents the number of ounces of peanuts in the mixture is N(x)=x.

A farmer wants to build two fenced-off sections within his field, one in the shape of a rectangle and the other in the shape of a square. The side of the square must be equal to the width of the rectangle, x feet. The length of the rectangle must be 50 feet longer than its width. The field the farmer wants to build the two fenced sections in has an area of y square feet. The difference of the area of this field and the area of the fenced, square section needs to be at least 1,000 square feet. In addition, the sum of the fenced areas must be less than the area of the field. This is the system of inequalities that represents this situation. Which points represent viable solutions?

y = 7x-3
Rearrange the equation to make x the subject
Answers
Step-by-step explanation:
y = 7x - 3
To make x the subject, you need to isolate it. (Get x by itself)
y = 7x - 3
Add 3 on both sides...
y + 3 = 7x
Divide by 7 (Maybe your teacher wants 7x = y = 3 but if she doesn't and wants x completely by itself here's the answer)
x = y/7 + 3/6

radius of cone and hemisphere are the same
volume of half sphere=(1/2)*(4/3)*
=(1/2)*(4/3)*3.14* (4*4*4=64)
