One acre is equal to 43,560 square feet. To convert acres to square feet, you can multiply the number of acres by 43,560.

For example, if you want to convert 6 acres to square feet, you can multiply 6 by 43,560:

6 acres x 43,560 square feet/acre = 261,360square feet

So, 6 acres is equal to 261,360square feet.

Acres and feet are area and length measurement units, respectively. There is no direct conversion between acres and feet because they measure different things. However, you can convert acres to square feet using a conversion factor.

Please keep in mind that this conversion only applies to area measurements. If you need to convert linear measurements from acres to feet, you'll need more information about the area's shape and dimensions.

To make it easy, if there are 3 yellow, 2 green, and 8 total, just find the equation that has the fraction result of 5/8.

The number of dimples per square centimeter are on the surface of a golf ball is 0.17, the correct option is A.

Suppose that radius of the considered sphere is of 'r' units.

Then, its surface area S would be:

[tex]S = 4\pi r^2 \: \rm unit^2[/tex]

We are given that;

The circumference= 13.408cm

Number of dimples = 336

Now,

2pi*r= 13.408

r= 13.408/2*3.14

r=2.13

Surface area= 4*pi*r^2

=4*3.14*2.13*2.13

=56.98

336dimple=56.98cm^2

Answer:

unit rate = $ 10 per km.

y = 10x

Step-by-step explanation:

Unit rate:

    Cost of travelling 1 km is $ 10. So, unit rate is $10

Equation:

       If 'x' km distance is travelled, then cost 'y',

              y = x * unit rate

               y = x * 10

               y = 10x

The expression f - 5(2f – 3) is equivalent to two other expressions, option (a) -11f-3 and option (b) -11f + 15.

In mathematics, an expression is a combination of symbols, operated on by certain mathematical operations to create a numerical value or a function.

To understand why this is the case, let's break down the expression.

The first part of the expression is just the variable f, so that is unchanged. The second part involves the multiplication of -5 and (2f – 3).

To evaluate this part, we need to use the order of operations. First, we multiply -5 and 2f and get -10f.

Then, we subtract 3 from this result and get -11f.

Therefore, the expression f - 5(2f – 3) is equivalent to -11f-3 and -11f + 15.

Answer:

Step-by-step explanation:

x is one blanket

y in one sheet

3x+y=190

2y+x=100

y=190-3x

2y+x=100

replace the y in the second equation with the first one

2(190-3x)+x=100

380-6x+x=100

380-5x=100

-5x=100-380

-5x=-280

x= -280/-5

x=56

replace the x with 56 so you can find the y

2y+56=100

2y=100-56

2y=44

y=44/2

y=22

so one blanket is 56 and a sheet is 22

1.5 kilograms of eggs is equivalent to approximately 3.31 pounds. Both kilograms and pounds are weight measuring units.

To convert kilograms to pounds, we can use the conversion factor that 1 kilogram is equal to 2.20462 pounds.

So to convert 1.5 kilograms of eggs to pounds, we can multiply 1.5 by 2.20462:

1.5 kilograms x 2.20462 pounds/kilogram = 3.30693 pounds

Therefore, 1.5 kilograms of eggs is equivalent to approximately 3.31 pounds. Both kilograms and pounds are weight measuring units. Kilograms are the primary unit of measurement for weight in the International System of Units (SI), while pounds are the primary unit of measurement for weight in the United States and other countries that use the imperial system of units. A kilogram is roughly equivalent to 2.20462 pounds. Kilograms are often used for scientific or medical purposes, while pounds are more commonly used for everyday weight measurements, such as for people's body weight or for weighing food in recipes.

When you create a dot plot, the operations that you have to do are:

c. Place a dot along a horizontal scale for each observation.

d. "Pile up" dots that are too close to show separately

A dot plot is a simple way of representing numerical data. It consists of a horizontal axis and a series of dots that are placed along it to represent the values of individual observations. Each dot corresponds to one observation, and its position along the axis represents its value.

Option (a) is not correct because a dot plot typically does not have a vertical axis showing frequency of observations. Option (b) is not correct because connecting adjacent dots to create a polygon is not a common practice in dot plots. Instead, each dot represents a single observation, and dots are placed along a horizontal scale to show their value. If multiple observations have the same value, they are "piled up" on top of each other to avoid overcrowding the plot.

To construct the inscribed circle of abc we have several steps of construction

Step 1: First step is to construct the incenter with the help of angle bisectors of two base vertices.

Here given d center of inscribed circle that means the incenter given.

Step 2: After incenter, draw a line perpendicular to one side of triangle that passes through incenter and the label the point of intersection.

This is very important step because after labelling measure the radius(same as the distance between the incenter and labelled point) and draw the circle.  

Hence, after incenter The next step is to construct the altitude from the incentre  to a side of triangle and label the intersection point.

Step 2 is used draw inscribed circle when incenter already given.

A linear equation is an algebraic equation of the form y = mx+b, where m is the slope and b is the y-intercept, and only a constant and a first-order (linear) term are included. Sometimes, the aforementioned is referred to as a "linear equation of two variables," with y and x serving as the variables.

Given, a linear equation that passes through the points (5,0) and (0, -7)

The slope-intercept form of the equation of a line

y=mx+b,

where m is the slope

b is the y-intercept

since, slope = (y - y')/(x -x')

In our case,

slope = (-7 -0)/(0-5)

slope = 7/5

b = -7

= 1/2 log₂(xy) - log₂(x+6)^5 (using the first two identities)

The interest for the given principal , time and rate is $ 51.06 . The Amount after interest is $ 976.06.

Simple interest is the amount of borrowing-related interest that is calculated using only the original principal and a constant interest rate. Compounding, in which borrowers end up paying interest on principal and interest that increases over a few of payment periods, is not a part of it.

Simple Interest = [tex]\frac{P*R*T}{100}[/tex]

where, P = principal, R = Rate of interest, T = Time.

Now in the given question,

Principal = $925

Rate= 2.3 %

Time = 2.4 years

Then,

Simple Interest,

                           [tex]=\frac{P*R*T}{100} \\\\=\frac{925*2.3*2.4}{100} \\\\=$51.06[/tex]
