The perimeter of a rectangular field is 84 yards. The ratio of the length to the width is 2:1. What are the length, width and area of the field?
Given:
the perimeter of a rectangular field is 84 yardsthe ratio of the length to the width is 2:1To find:
the lengththe widththe areaAnswer:
Let's assume that the length is 2x and the width is 1x.
We know that the formula to find the perimeter of a rectangle is as follows:
Perimeter = 2 × (Length + Width)
Substituting the values that we have, into the formula above,
84 = 2 × (2x + 1x)
84 = 2 × 3x
84/2 = 3x
42 = 3x
x = 42/3
x = 14
Since we know the value of 'x', let's use it to find the length and the width.
Length = 2x = 2 × 14 = 28
Width = 1x = 1 × 14 = 14
Since we now know the length and the width, let's find the area of the rectangle.
The formula to find the area of a rectangle:
Area = Length × Width
Substituting the values we have into the formula,
Area = 28 × 14
Area = 392
Therefore, the area of the rectangle is 392 square yards.
Hope it helps. :)

A carpenter bought 5 identical boxes of nails. She used 25 nails fir a project and now has 435 nails left. Which equation can be solved to find the number of nails in each box.
Answer:
The equation that can be solved to find the number of nails in each box =
5x = 460
The number of nails in each box = 92 nails
Step-by-step explanation:
A carpenter bought 5 identical boxes of nails. She used 25 nails for a project and now has 435 nails left. Which equation can be solved to find the number of nails in each box.
Let the number of nails in each box be represented by x
Therefore our Equation =
5x = 25 + 435
5x = 460
Solving for x
5x/5 = 460/5
x = 92 nails
Therefore, the number of nails in each box = 92 nails

A triangle has side lengths of 1.9cm, 2.7cm and 3.3cm, all measured to 1 decimal place could this be a right angled triangle
Answer:
Yes
Step-by-step explanation:
A triangle is a "right" triangle if its lengths fullfil the Pythagorean theorem:
[tex]a^2+b^2=c^2[/tex]
Here, a and b are the shorter "legs" of the triangle, adjacent to its right angle, while c is the "hypotenuse," the longest side and the one opposite the right angle.
If we call the 1.9 cm and 2.7 cm our legs, the sum of their squares is:
[tex]2.7^2+1.9^2=10.9[/tex] cm
While squaring our hypotenuse gives us
[tex]3.3^2=10.89[/tex] cm
The fact that we measured the triangle's side lengths to 1 decimal point of accuracy means that there's a little margin of error baked into the measurement. The two previous calculations are within 0.01 cm of each other, which is more than close enough, so we can say that yes, this could be a right triangle.

A towns population increases from 200000 to 250000. What has been the percentage increase?
Answer:
25% increase
Step-by-step explanation:
Just do 250000/200000 you will find 1.25
And the one is the base 200000 and convert .25 to percentage, which is 25%
Brainliest maybe?
Answer:
25% or .25
Step-by-step explanation:
fist find the number it increased by minus 250000 from 200000
250000 - 200000 = 50000
then divide the increase by the original
50000/200000 = .25 or 25%

44 cu. cm of wire is drawn into a wire of diameter 2 mm , the length of wire will be _____.
Given:
44 cu. cm of wire is drawn into a wire of diameter 2 mm.
To find:
The length of the wire.
Solution:
We know that,
1 cm = 10 mm
1 cu. cm = 1000 cu. mm
We have, a wire of cylindrical shape.
Volume of the wire = 44 cu. cm
= 44000 cu. mm
Radius of the wire = 2 mm
Volume of a cylinder is:
[tex]V=\pi r^2h[/tex]
Where, r is the radius and h is the height.
Putting V=44000, [tex]\pi=\dfrac{22}{7}[/tex] and r=2, we get
[tex]44000=\dfrac{22}{7}\times 2^2\times h[/tex]
[tex]44000\times \dfrac{7}{22}=4h[/tex]
[tex]14000=4h[/tex]
Divide both sides by 4.
[tex]\dfrac{14000}{4}=h[/tex]
[tex]3500=h[/tex]
Therefore, the length of the wire is 3500 mm or 350 cm.

Answer:

The fraction form of the expression is -1/7776.
What is an expression?An expression contains one or more terms with addition, subtraction, multiplication, and division.
We always combine the like terms in an expression when we simplify.
We also keep all the like terms on one side of the expression if we are dealing with two sides of an expression.
Example:
1 + 3x + 4y = 7 is an expression.
3 + 4 is an expression.
2 x 4 + 6 x 7 – 9 is an expression.
33 + 77 – 88 is an expression.
We have,
[tex](-1/6)^5[/tex]
This can be simplified as,
= [tex]\frac{(-1)^5}{6^5}[/tex]
= -1/7776
Thus,
The fraction form of the expression is -1/7776.

Answer:
Rate = 4%
Step-by-step explanation:
Simple interest = (principal × rate × time) / 100
Principal = $399.00
Rate = ?
Time = 2 years
Interest = $31.92
Simple interest = (principal × rate × time) / 100
31.92 = (399 * x * 2) / 100
31.92 = 798x / 100
Cross product
31.92 * 100 = 798x
3192 = 798x
x = 3192 / 798
x = 4%

Maxine find a dress on sale for 10% off at a boutique.The original price was $62, Maxine must also pay 6.75% sales tax.What is the final cost of the dress?
10% off means she pays 90% of the original price. (100% - 10% = 90%)
62 x 0.90 = 55.80 the sale price of the dress is $55.80
Now add the tax by multiplying the sale price by 1 + tax rate:
55.80 x 1.0675 = 59.57
She paid $59.57
Answer:
10% off means she pays 90% of the original price. (100% - 10% = 90%)
62 x 0.90 = 55.80 the sale price of the dress is $55.80
Now add the tax by multiplying the sale price by 1 + tax rate:
55.80 x 1.0675 = 59.57

A fort had enough provisions for 100 men for 8 days. If 60 more men were joined then how many days the provisions will last for?
Answer:
It would last for 3.2 days.
Step-by-step explanation:
100 men = 8 days
10 men = 0.8 days
60 men = 0.8 x 6 = 4.8 days
Now you subtract the days of 100 men and 60 men
8 - 4.8 = 3.2 days

A plane intersects the center of a sphere
with a volume of about 9,202.8 m3. What is
the area of the cross section? Round to the
nearest tenth.
Answer:
530.66
Step-by-step explanation:
The computation of the area of the cross section is shown below
Given that
Volume = 9208 m^3
Now let us assume the radius be r
So volume = 4 ÷ 3 πr^3
9202.8 × 3 ÷ 4π = r^3
27,608.4 ÷ 4 × 3.14 = r^3
27,608.4 ÷ 12.56 = r^3
2,198.12 = r^3
r = 13
Now the area of the cross section is
= πr^2
= 3.14 × (13)^2
= 530.66

Leann works at a restaurant for dinner there is a choice of three main dishes and two sides main dish Burger chicken pasta sides Apple fry Rena list possible ways a person could order your main dinner see this these combination is in the correct you to drop down menu to explain your reasoning
Answer:
(a) Leann is incorrect
(b) For every main dish, there are 3 sides
(c) 6 selections
Step-by-step explanation:
See attachment for complete question
Given
Main Dish: Burger (B), Chicken (C), Pasta (P)
Sides: Apple (A), Fries (F)
Solving (a): Is Leann list correct?
From the question, the list is: BA, BF, CA, CF, PA, PF, AB, FB, AC, FC, AP, FP
This list is incorrect because:
AB is the same BA, BF is the same as FB and so on
Solving (b): Number of sides for each Main dish
From the question:
[tex]Main\ dish = 2[/tex]
[tex]Sides = 3[/tex]
This implies that:
For every main dish, there are 3 sides
Solving (c): Total number of selection
In (b), we have:
[tex]Main\ dish = 2[/tex]
[tex]Sides = 3[/tex]
So: the total is:
[tex]Total = Main\ dish * Sides[/tex]
[tex]Total = 2 * 3[/tex]
