Rosa has a rectangle shaped backyard where the length is two less than twice the width. If the area of the garden is 420 square feet, find the dimensions of Rosa's garden?

Answers

Answer 1
The expression for the area of a rectangle is given by:
 A = (w) * (l)
 Where,
 l: long
 w: width
 the length is two less than twice the width:
 l = 2w-2
 Substituting the values:
 420 = (w) * (2w-2)
 We rewrite the expression:
 210 = (w) * (w-1)
 210 = w ^ 2-w
 w ^ 2-w-210 = 0
 The roots of the polynomial are:
 w1 = -14
 w2 = 15
 We discard the negative root.
 Width:
 w = 15
 Long:
 l = 2w-2
 l = 2 (15) -2
 l = 30-2
 l = 28
 Answer:
 the dimensions of Rosa's garden are:
 w = 15 feet
 
l = 28 feet

An Investor invested a total of $2,600 in two mutual funds. One fund earned 7% profit while the other earned 3% profit. If the investor’s total profit was $150, how much was invested in each mutual fund?

Answers

let x = amount invested at 3%

so, (2600 - x) is invested at 7%

.07 *(2600 - x) + .03 *(x) = 138

182 - .07x + .03x = 138

-.07x + .03x = 138 - 182

-.04x = -44

-.04x / -.04 = -44 / -.04

x = 1,100

so amount invested at 7% is (2600 - 1100) or 1500

consequently amount invested at 3% is 1100

$1,100 invested at 3%

$1,500 invested at 7%

The money invested in both of the funds are $800 and $1800 respectively.

What is percentage?

A percentage is a value that indicates 100th part of any quantity.

A percentage can be converted into a fraction or a decimal by dividing it by 100.

Suppose the money invested in one of the funds be x.

Then, in the other fund the investment is (2600 - x).

Now, the equation for the total profit from both investments can be obtained as,

7% × x + 3% × (2600 - x) = 150

⇒ 7/100 × x + 3/100 × (2600 - x) = 150

⇒ 4x/100 = 150 - 78

⇒ x = 1800

Thus, the investment in the other fund is 2600 - 800 = $800.

Hence, the investment for both the funds are $800 and $1800 respectively.

The volume of the cylinder with given diameter and height is 136.02 cm³.

What is the volume?

Volume is the measure of the capacity that an object holds.

Formula to find the volume of the object is Volume = Area of a base × Height.

Given that, the diameter of a cylinder =7.6 cm and the height of a cylinder = 3 cm.

Radius =7.6/2 =3.8 cm

We know that, the volume of a cylinder is πr²h

Now, volume = 3.14×3.8²×3

= 136.02 cm³

solomon has read 1/3 of his book. He finishes the book by reading the same amount eat night for 5 nights what fraction of the book does he read each of the 5 nights?

Answers

The answer is 2/3 for a fraction and the decimal number is 0.6666666667

Final answer:

Solomon has 2/3 of the book left to read. To finish it over 5 nights, he needs to read 2/15 of the book each night.

Explanation:

Solomon has read 1/3 of his book already. To finish the remaining 2/3 of the book in 5 nights, we need to calculate the fraction of the book he should read each night. Since he has to evenly distribute the remaining portion over 5 nights, we will divide 2/3 by 5.

Here's the calculation step-by-step:

First, represent the remaining part of the book as a fraction, which is 2/3.

To divide this fraction by 5, we multiply the denominator by 5. This gives us (2/3) × (1/5).

Multiplying these fractions, we get (2 × 1) / (3 × 5), which simplifies to 2/15.

Thus, Solomon reads 2/15 of the book each night for the next 5 nights.

Which expression is equivalent to 32?

Answers

Final answer:

The expression equivalent to 32 might refer to a mathematical manipulation or a unit conversion. In equations, 32 is what remains when you subtract 32 from one side of an equation like x + 32 = 64. Meanwhile, in conversions, multiplying the number of quarts by 32 gives you the equivalent volume in fluid ounces.

Explanation:

The expression is equivalent to 32 and could be interpreted in different contexts. Using mathematical manipulation, when you subtract 32 from both sides of an equation, the equality holds. For example, if you have an equation like x + 32 = 64, subtracting 32 from both sides gives us x = 64 - 32, which simplifies to x = 32. This demonstrates an application of the principle that you can add or subtract the same number from both sides of an equation without changing its solution.

In relation to conversion between different units of measurement, specifically volume, when you convert quarts to fluid ounces, the conversion factor is 32 because there are 32 fluid ounces in one quart. Consequently, to find how many fluid ounces are in a given number of quarts, you multiply the number of quarts by 32. For example, 4 quarts equal 4 × 32, which is 128 fluid ounces.

Furthermore, when dealing with electrical resistance, 'equivalent resistance' is another situation where the number 32 might be relevant. Depending on the context and the specific details of an electrical circuit, one of the listed equivalent resistances may be the correct answer to a problem involving calculating the total resistance.

Two points are located at (−9,−8) and (−6,−4) . Complete the equations below to show how you can use the Pythagorean theorem to find the distance between these two points.

Answers

Final answer:

The distance between two points in a coordinate plane can be found using the Pythagorean theorem. For the points (-9,-8) and (-6,-4), the distance is 5 units.

Explanation:

The Pythagorean theorem can be used to find the distance between two points in a coordinate plane. To find the distance between the points (-9,-8) and (-6,-4), we can consider the horizontal and vertical differences as the legs of a right triangle. The horizontal difference is 3 and the vertical difference is 4.

Using the Pythagorean theorem, we have:
a^2 + b^2 = c^2
3^2 + 4^2 = c^2
9 + 16 = c^2
25 = c^2
c = sqrt(25) = 5

Therefore, the distance between the two points is 5 units.

Rewrite the following equation in slope-intercept form. 10x − 17y = -12 Write your answer using integers, proper fractions, and improper fractions in simplest form.

Answers

Answer:
y = (10/17) x + (12/17)

Explanation:
The slope-intercept form has the following formula:
y = mx + c
where:
m is the slope
c is the y-intercept

The given is:
10x - 17y = -12

To put this in slope-intercept form, we need to isolate the y as follows:
10x - 17y = -12
17y = 10x + 12
y = (10/17) x + (12/17)
where:
m is the slope = 10/17
c is the y-intercept = 12/17

Y = 0
10x = -12
X = -12/10 = -6/5

X=0

The statement is true. However, it is not related to intersection between lines. Therefore, this choice is wrong

Choice B: Through any two different points, exactly one line exists
This postulate is true. However, it does not relate directly to the intersection between lines. Therefore, this choice is wrong

it has to be a negative number because 60 is greater than -30

Answers

Final answer:

Yes, the equation provided can be used to calculate the original price of the phone case. After solving the equation, we found out that the original price of the phone case was approximately $80.

Explanation:

Yes, the equation you provided, 3/4(0.7c) = 42, can certainly be used to find the original price of the phone case (c). The equation is obtained by recognizing that you're receiving two discounts: a 30% or 0.3 discount off the original price (leaving 70% or 0.7 of the original price) and then a 25% or 0.25 discount (meaning you're paying 75% or 0.75 of the price after the first discount).

To find the original price, you want to solve this equation for 'c'. That would involve dividing both sides by 3/4(0.7) equaling to 0.525. So, it will look like: 42 ÷ 0.525 = c. Doing the calculation, c equals approximately $80.

Therefore, the original price of the phone case was $80.
