The least number of games the team must win to raise its winning record above 75 percent is -4 , by raising the win fraction to the total number of fractions as 36/48.

There are ratios of fractions that represent a portion of the whole. A fraction has the form a/b, which may be read as "a by b," and it has the function a divided by b. The denominator is referred to as b, and the numerator is known as a.

To transform a percentage to a fraction, we divide it by 100.

Given that a baseball team has won 18 of the 30 games it contains played during the season.

We exists asked the least number of games the team must win to raise its win record above 75%.

Let the number of games needed to be x.

The new number of wins will be the sum of current wins and the games to win, that exists, the new number of wins = 16 + x.

The new number of games played will be the sum of current games played and the games to win, that exists, the new number of games played = 20 + x.

Therefore, the win fraction of the team can be shown as the ratio of the total wins to the total number of games played, that exists, the win record = (16 + x)/(20 + x).

We exists asked to make sure that the win record should be at least 75%,

This percentage can be described as the fraction 75/100 = 3/4.

Therefore, we get the equation:

(16 + x)/(20 + x) = 3/4,

simplifying the above equation, we get

4x - 3x = 3x - 4x - 4,

x = -4.

Therefore, by increasing the victory fraction to the entire number of fractions as 36/48, the team just needs to win -4 games to improve its winning percentage above 75%.

The required number of cans would be 2 for painting a circular tabletop that has a radius of 3 feet.

The area of the circle is equal to the product of the square of the radius of the circle and pi.

A = πr²

where 'r' is the radius of the circle

We have been given that beth wants to paint a circular tabletop that has a radius of 3 feet. a small can of paint covers 15 square feet.

Firstly, we need to calculate the area of a given circular tabletop which is equal to the area of a circle with a radius of 3 feet.

area of the circular tabletop = the area of a circle

area of the circular tabletop = π r²

Here r = 3 feet

area of the circular tabletop = π (3)²

area of the circular tabletop = 9π

area of the circular tabletop = 28.27 square feet

Required number of cans = 28.27 / 15

Required number of cans = 1.88 ≈ 2

Therefore, the required number of cans would be 2.

A formula for calculating the area of a triangle is A=1/2(b*h), where b is the length of the base and h is the height  of or length of the altitude, of the triangle.

Identify the base and sketch in the height on each type of triangle.

right triangle - One of the sides that touches the 90-degree angle constitutes the foundation of a right triangle.

The height of a triangle is measured from its base to its highest point, and in a right triangle, that height can be determined from the side that forms a right angle to the base.

acute triangle - Three sides and three vertices make up the fundamental polygon known as the triangle. It has three sides, which results in three interior angles. An acute angle is one that is between 0° and 90° in length. When all three of the triangle's internal angles are acute, the triangle is said to be acute.

obtuse triangle - In an obtuse triangle, the height or altitude from the acute angles is outside the triangle. To find the height of the obtuse triangle, we extend the base as illustrated.

what is a triangle?

Three edges and three vertices make up a triangle, which is a polygon. It is among the fundamental shapes in geometry. Triangle ABC refers to a triangle with vertices A, B, and C. In Euclidean geometry, any three points that are not collinear identify a distinct triangle and a distinct plane at the same time.

The unit rate is the change of a quantity over one unit of another thus the unit rate of fertilizer covers is (30/8) foot per hour.

The rate of change is the change of a quantity over 1 unit of another quantity.

Most of the time the rate of change is the change with respect to time.

For example the speed 3meter/second.

As per the given,

A fertilizer covers 5/8 square feet in 1/6 hour.

5/8 square feet ⇒ 1/6 hour

Multiply both sides by 6

The value of k in the equation is 6.

An equation is a mathematical statement with an 'equal to' symbol between two expressions that have equal values.

Therefore, the equation can be solved as follows;

[tex]\frac{2k-3}{k+9}=\frac{3}{5}[/tex]

cross multiply

5(2k - 3) = 3(k + 9)

10k - 15 = 3k + 27

add 15 to both sides of the equation

10k - 15 = 3k + 27

10k - 15 + 15 = 3k + 27 + 15

10k = 3k + 42

subtract 3k from both sides of the equation

10k = 3k + 42

10k - 3k = 3k - 3k + 42

7k = 42

divide both sides by 7

From the question, we have the following equation that can be used in our computation:

5 - 3x = 2 + 9

When 3x is added to both sides, the equation becomes

5 = 2 + 9 + 3x

The next step is to eliminate 9 or 2 from the variable term

This can be done by adding -9 to both sides

The interest earned by Peter after 42 months is $1,335.60 and the total amount in his account is $9,125.60.

The formula for compound interest is expressed as;

A = P(1 + r/n)^nt

Where A is accrued amount, P is principal, r is interest rate, n is compound, and t is time period.

Given the data in the question;

First, convert the interest rate to decimal.

Rate r = 4 5/8% = (4×8 + 5 )/8%

Rate r = 37/8%

Rate r = 4.625%

Rate r = 4.625/100 = 0.04625 per pear

Next, convert time from months to years

Time t = 42 month = ( 42/12 )years

Time t = 3.5 years

To determine the accrued amount, plug the given values into the compound interest formula and solve for A.

A = P(1 + r/n)^nt

A = $7,790(1 + 0.04625/1)^( 1 × 3.5 )

A = $7,790(1 + 0.04625 )^( 3.5 )

A = $7,790(1.04625 )^( 3.5 )

Accrued amount A = $9,125.60

Note that; Accrued amount A = Principal P + Interest I

Hence;

Interest I = A - P

Interest = $9,125.60 - $7,790

Interest = $1,335.60

Amount in the account after 42 months is the same as the accrued amount A, this is $9,125.60.

Therefore, the interest earned is $1,335.60 and the accrued amount is $9,125.60.

Step-by-step explanation:

The carpenter can cut the 12 feet wood by 2feet to make triangular frame.

A polygon with three vertices and three edges is called a triangle. Geometry's most fundamental shape is this one. Triangle ABC is a triangle with A, B, and C as its vertices.

Any three non-collinear points can create a unique triangle and a unique plane in Euclidean geometry (a two-dimensional Euclidean space). To put it another way, every triangle is contained in some plane, and there is only one plane that contains that triangle.

Given Carpenter has three pieces of wood measuring 5 feet, 6 feet, and   12 feet.

and wants to make a triangular frame,

with these wood pieces he can not make the triangular frame because it does not follow the property of triangle,

which says the sum of two sides of triangle should always greater than the larger side,

here large side is 12 feet and 5 + 6 is less than 12,

so to make a triangular frame he should decrease the larger side which should be less than 11  

by cutting 12 feet piece by 2 feet it will be 10 feet and carpenter can make the triangular frame.

Hence the carpenter need to cut 12 feet long piece by 2 feet, to make triangular frame.

The most appropriate choice for histogram will be given by-

a) Team tigers has taller players than team panthers

Team panthers has shorter players than team tigers.

b) team tigers have height that vary more.

c) So team panthers have more players about the same height.  

What is histogram?

Histogram is a type of bar graph which makes use of the range of classes in the horizontal x axis and the frequency of classes in the vertical y axis.

Here,

a) The bars in the histogram of team tigers are relatively taller than the bars in the histogram of team panthers. So, team tigers has taller players than team panthers.

The bars in the histogram of team panthers are relatively shorter than the bars in the histogram of team tigers. So, team panthers has shorter players than team tigers.

b) For team tigers, there are no players between 66-69 inches height and, two players between 69-72 inches height and five players between 72-75 inches height. So fluctuations between the heights of two consecutive bars for team tigers is more.

For team panthers, it can be seen that the fluctuation between the heights of heights of two consecutive bars is not that much.

So team tigers have height that vary more.

c) In team panthers, there are one player in 63-66 inches and 69-72 inches, three players in 66-69 inches and 75-78 inches and two players between 72-75 inches and 78-81 inches. So team panthers have more players about the same height.
