The area of each square is 16 square units. Find the perimeter of the figure. (see imagine attached) :)

Using algebra, we conclude that the dollar amount of meals Jerome served this weekend is $1150.

Given: The total amount Jerome earned this weekend is $252.50.

           He earned every weekend = $80.

            He earned 15% of the cost of meals as tips by serving them.

To find: The cost of meals served by Jerome in this weekend.

The total amount, $252.50,  is the sum of the tips amount Jerome earned from serving meals and sum of the amount Jerome earned every weekend. To solve this, we must first translate the conditions of the problem, into an algebraic expression with a variable referring to the unknown quantity. This expression is then converted to an equation to find the value of the unknown quantity.

Let x be the cost of meals that Jerome served this weekend.

The equation for the problem statement becomes

[tex]\$80 + \frac{15}{100} x = \$252.50\\\\[/tex]

Keeping only the x term on the left side of the equation and constant terms on the right side we get

[tex]\frac{15}{100} x = \$252.50 - \$80\\\\\frac{15}{100} x = \$172.50\\\\\\[/tex]

Multiply both the sides of the equation by 100

[tex]\frac{15}{100} x \times 100 = \$172.50 \times 100\\\\15x = \$17250[/tex]

Divide both sides of the equation by 15

[tex]\frac{15x}{15} = \frac{\$17250}{15}\\\\x = \$1150[/tex]

Algebra is a field of mathematics in which letters are substituted for numbers, and an algebraic equation depicts a scale in which what is done on one side of the scale is likewise done on the other side of the scale, with the numbers acting as constants.

An equation is a mathematical statement that two expressions are equal. If it is an algebraic equation, two algebraic expressions has to have the same value  on either side of the equal sign.

A meaningful collection of numbers, variables, and signs (positive or negative) of operations that must make mathematical and logical sense is referred to as an algebraic expression.

Expressions contain any number of algebraic terms. They use signs of operation like addition, subtraction, multiplication, and division and also do not contain an equality sign (=).

Using algebra, we conclude that the dollar amount of meals Jerome served this weekend is $1150.

Answer:

12 miles in 15 minutes

Step-by-step explanation:

To find the car's rate in miles per minute, we can divide the rate in miles per hour by the number of minutes per hour. There are 60 minutes in an hour, so the car's rate in miles per minute is 48 miles per hour / 60 minutes per hour = 0.8 miles per minute.

To find the number of miles the car will travel in 15 minutes, we can multiply the rate in miles per minute by the number of minutes. The car will travel 0.8 miles per minute * 15 minutes = 12 miles in 15 minutes.

(i) 263.9 meters sheet of metal is required.

(ii) 1847.25 liters of water can this tank hold.

(iii) Rupees 27841.45 cost of whitewashing this tank at the rate of rupees 105.5 per 2.

Given that,

A open cylindrical tank of radius 14 meters and height 3 meters is made of sheet metal.

We have to find

(i) The quantity of metal sheet needed.

(ii) How much water this tank is capable of holding.

(iii) How much would it cost to whitewash this tank at a rate of 105.5% per square foot?

We know that,

(i) To find the sheet required of metal is

Curved surface area of cylinder =2πrh

Here,

r is 14 and h is 3

=2π(14)(3)

=84π

=263.9

Therefore, 263.9 meters sheet of metal is required.

(ii)To find how much liters of water can tank hold.

Volume of the cylinder =πr²h

=π(14)²(3)

=588π

=1847.25

Therefore, 1847.25 liters of water can this tank hold.

(iii) To find the cost of whitewashing this tank at the rate of rupees 105.5 per 2.

=263.9×105.5

=27841.45

Therefore, Rupees 27841.45 cost of whitewashing this tank at the rate of rupees 105.5 per 2.

Yes, this sample of the flowers in the neighborhood is likely to be biased. This is because the number of flowers observed on each block is relatively small and may not be representative of the entire neighborhood.

A neighborhood is a local geographic area typically containing a cluster of families and individuals who live nearby and interact with each other. It is usually a residential area, although some neighborhoods may be mixed-use, containing both residential and commercial buildings. Neighborhoods are typically identified by geographical boundaries such as a street, a park, or a body of water. People living in a given neighborhood often share certain characteristics including socio-economic status, culture, ethnicity, and even language. Neighborhoods play an important role in the lives of individuals and families, providing a sense of belonging, safety, and identity.

Additionally, if there is any external factor that influences the number of flowers on certain blocks (such as the amount of sunlight or water) then the sample may be skewed.

Step-by-step explanation:

Given that μ = 144, σ = 27:

For x = 90: z= 90-144/27=-2

For x = 117: = 117-144/27 = -1

Let X represent a random variable which represents the proportion all school graduates who secure employment in their profession of choice within a year of graduation:

With a binomial distribution,

X has a n = 5 and a p value of 0.57.

n = number of trial.

p = probability of success

x = number of success.

A binomial distribution's probability mass function is provided by:

P(X = x) = ⁿCₓ . pˣ . qⁿ⁻ˣ

The likelihood that at least one gets employment in their field of choice within a year after graduation:

P(X ≥ 1) = 1 - P(X < 1)

P(X ≥ 1) = 1 - P(X = 0)

P(X ≥ 1) = 1 - ⁵C₀ . (0.57)⁰ . (0.43)⁹⁻⁰

For the construction of an inscribed circle the required construction that must be known is the angle bisector. The correct option is (A).

The angle bisector is a line that divides an angle into two equal parts. For a circle inscribed in a triangle the line joining the center to the vertex is the angular bisector of the interior angle.

The diagram for the given case can be drawn as follows,

For the circle inscribed in the circle, all the sides are tangents.

By the property of tangents to a circle ∠ODB and ∠OFB are right angles.

Now, in ΔODB and ΔOFB the relation is obtained as,

∠ODB = ∠OFB  (right angles)

OB = OB           (Common sides)

And, OD = OF  (radius of the circle)

⇒ ΔODB ≅ ΔOFB (by RHS criteria)

This implies that ∠ODB ≅ ∠OFB.

Thus, the line joining the centre and the vertex of triangle bisects its angles.

Hence, for the given case the required construction to be known is the angle bisector of triangle.
