A training field is formed by joining a rectangle and 2 semicircles. The rectangle is 89 m long and 66 m wide. Find the area of the training field. Use the value 3.14 for pie, and do not round your answer. Be sure to include the correct unit in your answer.

Answers

Answer 1

The answer is 6966.14 meters

Step 1: break the shape into 2, a rectangle and a circle and first find the area of the rectangle ( l x w or 89 x 66)

Step 2: now that we know that the area of the rectangle is 5874 we find the area of the circle (3.14 x radius^2), the diameter is 66, and the radius is 33 (diameter divided by 2)

Now that we know both the rectangle (5874 meters) and circles (1092.14 meters) we add them and get 6966.14

I hope this helps if I made a mistake pls let me know

25%

30%

Answers

I have to say 25% because 25% of 600 is 150. 600+150=750. So I hope this help!!!

The solution is, the percent of error, rounded to the nearest percent is 25%.

What is percentage?

A percentage is a number or ratio that can be expressed as a fraction of 100. A percentage is a number or ratio expressed as a fraction of 100. It is often denoted using the percent sign, "%", although the abbreviations "pct.", "pct" and sometimes "pc" are also used. A percentage is a dimensionless number; it has no unit of measurement.

here, we have,

given that,

While viewing a herd of cattle on a ranch, Herbert estimated that there were 750 cattle in the herd.

The actual number of cattle in the herd was 600.

now, we have to find the percent of error, rounded to the nearest percent.

so, we get,

Herbert estimated that there were 750 cattle in the herd.

The actual number of cattle in the herd was 600.

so, error = 750 - 600

= 150

so, we get,

the percent of error = 150 * 100 / 600

= 25%

Hence, The solution is, the percent of error, rounded to the nearest percent is 25%.

Answers

The parameters of the expression are given as

25w+55

variable=wcoefficient = coefficient of variable (w)=25constant=55

What is the coefficient ?

A multiplicative factor in some terms of a polynomial, a series, or an expression is referred to as a coefficient. Although a coefficient is often a number, it may really be any expression. It is possible to refer to the coefficients themselves as parameters in situations when they themselves are variables.

A sign that may stand in for any other item in mathematics is known as a variable. To be more specific, a variable may stand in for a numeric value, a vector, a matrix, a function, the argument of a function, a set, or an individual component of a set.

Generally, the equation for expression is mathematically given as

Point M is the midpoint of AB. The coordinates of point A are (-7, 1) and the coordinates of M are (-4,1). What are the coordinates of point B? The coordinates of point B are :

Answers

Answer:

The coordinates of point B are : (-1, 1)

Step-by-step explanation:

$\frac{-7+x^{2} }{2} = -4\\\frac{1+y^{2} }{2} =1$ You multiply -4 by 2 which gives you -8 then you multiply 1 by 2 which gives 2.

Then you create the equations $-7 + x^{2} = -8\\1 + y^{2} = 2$ you substitute -7 for +7 and add 7 to -8 which gives -1 ($x^{2}$) and subtract 1 from 2 which gives you 1 ($y^{2}$)

To check your answer use the midpoint formula $\frac{-7+-1}{2} =\frac{-8}{2} =-4\\\frac{1+1}{2} =\frac{2}{2} =1$ which gives you your midpoint (-4,1)

*Again*

24-16+2x2

24-16+4

*add the numbers*

24-16+4=12

Answer:

-4

Step-by-step explanation:

Since this equation uses order of operations, you should solve what's in the parenthesis first.

48 ÷ 2 = 24

Now you have 24 - 4²2 + 2 × 2. The next thing to solve in order of operations is exponents, so square 4.

4² = 16

Now you should have 24 - 16 (2) +2 × 2. Next is multiplication, so multiply 16(2) and 2 × 2.

16 × 2 = 32, and 2 × 2 = 4

Now you have 24 - 32 + 4. This should look a lot more simple now. Simply do the math from here; doesn't matter how.

24 - 32 = -8

-8 + 4 = -4

A new computer graphics company employs 10 programmers. The company decides to expand into digital animation and needs to transfer 3 of the programmers into the new department. How many different combinations of 3 programmers can be chosen to transfer to the new department?

A. 3

B. 30

C. 120

D. 840

Answers

There are 120 different combinations of 3 programmers that can be chosen to transfer to the new department

How to determine the ways of selection?

From the question, we have

Total number of programmers, n = 10

Numbers to programmers to select, r = 3

The number of ways of selection could be drawn is calculated using the following combination formula

Total = ⁿCᵣ

Where

n = 10 and r = 3

Substitute the known values in the above equation

Total = ¹⁰C₃

Apply the combination formula

ⁿCᵣ = n!/(n - r)!r!

So, we have

Total = 10!/(7! * 3!)

Evaluate

Total = 120

Hence, the number of ways is 120

D)

Answers

Answer: $\frac{10}{\sqrt{3}}$

This is equivalent to $\frac{10\sqrt{3}}{3}$

======================================================

Explanation:

To get the first value mentioned above, we simply divide the long leg (10) over the square root of 3.

This is due to the fact that if x is the short leg, then x*sqrt(3) is the long leg. We go in reverse of this process to go from long leg to short leg.

The expression $\frac{10}{\sqrt{3}}$ is the same as $\frac{10\sqrt{3}}{3}$ after we multiply top and bottom by sqrt(3) to rationalize the denominator.

Side notes:

This entire process only applies to 30-60-90 triangles.The hypotenuse of a 30-60-90 triangle is twice as long as the short leg, so the hypotenuse is $2x = 2*\frac{10\sqrt{3}}{3} = \frac{20\sqrt{3}}{3}$ units long. You could use the tangent ratio to help isolate x. You would either say tan(30) = x/10 or tan(60) = 10/x as the first equation to set up.

In some ANOVA summary tables you will see, the labels in the first (source) column are Treatment, Error, and Total. Which of the following reasons best explains why the within-treatments sum of squares is sometimes referred to as the “error sum of squares”?

Answers

The within-treatments sum of squares is sometimes referred to as the "error sum of squares" because it represents the amount of variability in the data that is not accounted for by the treatment effect. In other words, it represents the variability that is due to random error or chance factors that are not related to the treatment. The error sum of squares is used to estimate the variance of the population from which the samples were drawn. The F-ratio is then calculated by comparing the treatment mean square to the error mean square. If the treatment effect is significant, then the treatment mean square will be larger than the error mean square, resulting in a larger F-ratio and a rejection of the null hypothesis. Therefore, the error sum of squares is an important component of the ANOVA table as it helps to determine whether the treatment effect is significant or not.

The amount of tax on a chair was $3.60. The tax rate was 5%. Find the original price of the chair.

Bianca solved the problem below. Find Bianca’s error.

0.05(3.60) = Original price

The original price is $0.18.

Answers

9514 1404 393

Answer:

$72.00

Step-by-step explanation:

The relationship between price and tax is ...

tax amount = (tax rate) × (price)

Then the price can be found by dividing by the tax rate:

price = (tax amount)/(tax rate)

price = $3.60 / 0.05 = $72.00

The original price of the chair was $72.00.

Bianca apparently did not pay any attention to the way tax is computed. Nor did she check her work. The original price is not a small fraction of the tax. It is the other way around. Bianca used a wrong relationship between tax and price.
