A traffic cone with a height of 20 in. is ideal for traffic control. Find the lateral area of a cone with a height of 20 in. and a diameter of 12 in. Round the answer to the nearest whole number. (Hint: The height given is not the slant height.)
Answers
The lateral area of the cone is 394 square inches
How to determine the value
The formula for lateral area of a cone is expressed as;
Lateral area = πr √h² + r²
Given that;
height = 20 inDiameter = 12 in, radius = 12/ 2 = 6 inSubstitute the values into the formula
Lateral area = 3. 142(6) √20² + 6²
Lateral area = 18. 85 √436
Lateral area = 18. 85 × 20. 8
Lateral area = 394 square inches
Thus, the lateral area of the cone is 394 square inches

Answers
Number 50 in the Jack's equation represents the rate of change in the oven's temperature over time (per minute) or with respect to time by using the slope form concept.
As per the question statement, Jack is preheating his oven before using it to bake. He wants to predict the final temperature after [tex]x[/tex] minutes.
He wrote the equation [tex]y =50x+78[/tex] , where [tex]y[/tex] represents the final temperature in [tex]fahrenheit[/tex]. We are supposed to tell the significance of number 50 in the given equation.
As we know that the equation which is in the form of [tex]y=mx+c[/tex], or the slop form equation, m is called the slope or the rate of change of value of [tex]y[/tex] with respect to value of [tex]x[/tex].
And the given equation [tex]y =50x+78[/tex] is also of the form of [tex]y=mx+c[/tex] hence we conclude that 50 is the slope or the rate of change of value of [tex]y[/tex] with respect to value of [tex]x[/tex].
As y is the temperature in Fahrenheit therefore x is the time hence "50 Degrees Fahrenheit change of temperature per unit minute" is the significance of 50.

How do you express without exponents [tex](3a^3)^2[/tex]
Answers
__________________________________________________________
Hello! In this question, we were given an expression and would have to express it without the use of exponents.
__________________________________________________________
Explanation:
In the question, we were given:
(3a³)²
In order to express the expression without the exponents, we would have to first simplify it and then expand the expression.
__________________________________________________________
Solve:
[tex](3a^3)^2[/tex]
Simplify by "squaring" the variable inside the parenthesis, in which in this case we would multiply the "2" to the "3".
[tex]3a^6[/tex]
Now in this step, we would have to expand the expression in a different form to get rid of the exponent.
To get rid of the exponent, we would expand the " [tex]a^6[/tex] " term.
Note that the term [tex]a^6[/tex] is the same thing as a · a · a · a · a · a, it is just the expanded version of the exponent.
This means that our expressed expression without exponents, including our constant "3" would be:
3 · a · a · a · a · a · a
__________________________________________________________
Answer:
3 · a · a · a · a · a · a

2.29 x 106
Answers
2,290,000 in scientific notation is 2.29 x 10⁶.
What is scientific notation?Scientific notation is a way of expressing numbers that are too large or too small (usually would result in a long string of digits) to be conveniently written in decimal form. It may be referred to as scientific form or standard index form, or standard form in the United Kingdom. This base ten notation is commonly used by scientists, mathematicians, and engineers, in part because it can simplify certain arithmetic operations.
Converting a number in these cases means to either convert the number into scientific notation form, convert it back into decimal form or to change the exponent part of the equation.
Now the given number is,
2,290,000
To convert 2,290,000 into scientific notation, 2,290,000 must be converted into into decimal and multiples of 10.
So, factorizing 2,290,000 we get,
2,290,000 = 229 x 10,000
Now converting 10,000 into multiples of 10
Since, 10,000 = 10 x 10 x 10 x 10
So, 2,290,000 can be written as,
2,290,000 = 229 x 10 x 10 x 10 x 10
Multiplying and divide 229 by 100 we get,
2,290,000 = (229 x 100 x 10 x 10 x 10 x 10) / 100
Rearranging we get,
2,290,000 = (229 x 100) / 100 x (10 x 10 x 10 x 10)
Since, (229 x 100) / 100 = 2.29 x 100
2,290,000 = (2.29 x 100) x (10 x 10 x 10 x 10)
And 100 = 10 x 10
Therefore we get,
2,290,000 = 2.29 x 10 x 10 x 10 x 10 x 10 x 10
Since 10 x 10 x 10 x 10 x 10 x 10 = 10⁶
Therefore we get,
⇒ 2,290,000 = 2.29 x 10⁶
this is the required scientific notation of 2,290,000 .
Thus, 2,290,000 in scientific notation is 2.29 x 10⁶.

The banker should invest $ 30,000 at 6 % interest rate to earn an interest of 3800 per year from both the investments.
Principal 1 = $ 50,000
Rate 1 = 4 %
Let principal 2 be x
Rate = 6 %
Time = 1 year
Interest = 3800
Using simple interest, we get that:
SI = p × r × t
3800 = ( 50,000 × 0.04 × 1) + ( x × 0.06 × 1)
3800 = 2000 + 0.06 x
0.06 x = 3800 - 2000
0.06 x = 1800
6 x = 180000
x = 180000 / 6
x = 30,000
Therefore, we get that, the banker should invest $ 30,000 at 6 % interest rate to earn an interest of 3800 per year from both the investments.

In the following triangle, what is the value of n?
Answers
Given that the triangle is a right triangle, the value of sin (n) is √5/5.
Hence, option D)√5/5 is the correct answer.
What is the value of sin(n) in the triangle?Trigonometry is simply a branch in mathematics that looks into the relationships between angles and side lengths of a triangle.
Given the data in the question;
Hypotenuse = 2√5Opposite of angle n = 2Adjacent of angle n = 4To determine the value of sine n, we will use one of six functions of an angle commonly used in trigonometry.
Sine of angle n = Opposite of angle n / Hypotenuse
sin(n) = Opposite / Hypotenuse
Plug in the given values and simplify
sin(n) = Opposite / Hypotenuse
sin (n) = 2 / 2√5
Next, rationalize the denominator.
Cancel out the common factor 2.
sin (n) = 2 / 2√5
sin (n) = 1 /√5
Multiply both the numerator and the denominator by √5.
sin (n) = (1×√5) / (√5 × √5)
sin (n) = √5/5
Given that the triangle is a right triangle, the value of sin (n) is √5/5.

Answer:
Steve: $138

Step-by-step explanation:
If you're doing it so they each get what they sold, you would have to first add the total number of chocolate bars, giving you 35. To see how much each bar costs, you just have to divide $210 ÷ 35, giving you $6 per chocolate bar.
To give each what they gained, you multiply $6 by whichever amount you chose, 23 or 12, which will give you that person's amount. Steve will get $138 and Jenna will get $72.

When two fractions have the same value, they are said to be equivalent, meaning that even though the numbers in the two fractions are different, their overall value is the same.
Fractions that are not equal to one another are referred to as nonequivalent fractions. The same cross multiplication procedure must be used to determine whether two fractions are comparable or not.
Consider these two fractions,
x = ( m / 4n ) and y = ( 2m / 8n )
Now when the fraction x is multiplying and dividing by 2.

What do we mean by media?The median is the value that separates the upper and lower halves of a data sample, population, or probability distribution in statistics and probability theory. It is sometimes referred to as "the middle" value in a data set.

distance = rate*time
rate = distance/time

The total bill for 3.18 pounds of apples, 1.45 pounds of peaches, and 1.71 pounds of pears is $6.78 .
In the given question
The price of 1 pound apple = $0.99
The price of 1 pound Peaches = $1.09
The price of 1 pound Pears = $1.19
Total pounds of apples bought = 3.18 pounds
price of 3.18 pounds of apple = ( pounds of apple bought)*(price of 1 pound apple)
=3.18*0.99
=$3.15 ...(i)
Total pounds of Peaches bought = 1.45 pounds
price of 1.45 pounds of peaches = 1.45*1.09
= $1.59 ...(ii)
Total pounds of Pears bought = 1.71 pounds
price of 1.71 pounds of pears = 1.71*1.19
= $2.04 ...(iii)
Total bill = price of 3.18 pounds of apple + price of 1.45 pounds of peaches + price of 1.71 pounds of pears.
Substituting the values from equation (i),(ii)and (iii) we get ,
Total bill = $3.15 + $1.59 + $2.04
