What is the surface area of the right cone below?
Answer:
54 is anwer.
please mark me brainliest and follow me my friend.
because 54 is correct answer.
The value of surface area of the right cone is,
⇒ 54π units²
What is Multiplication?To multiply means to add a number to itself a particular number of times. Multiplication can be viewed as a process of repeated addition.
Given that;
Radius of cone = 3 units
Slant height = 15 units
Now, The formula for the total surface area of a right cone is,
T. S. A = πrl + πr²
Hence, We get;
The value of surface area of the right cone is,
⇒ π x 3 x 15 + π x 3²
⇒ 45π + 9π
⇒ 54π units²
Thus, The value of surface area of the right cone is,
⇒ 54π units²

Answer:
3 3/7 divided by 1 1/7 = 3
16/(-8) = -2
2 2/5 divided by 4/5 = -3
-12.2/(-6.1) = 2
Step-by-step explanation:
Turn the mixed numbers into improper fractions and work from there. Then, make sure to find the reciprocal of the second fraction/number. For example,
3 3/7 = 24/7
1 1/7 = 8/7
24/7 (7/8) = 3

Two sides of a triangle can be represented by the expressions 3x+8 and 2x2-4x+5.If the perimeter of the triangle is 4x2+2x-10, what expression can be used to represent the third side?
Answer:
s = 2x²+3x-23
Step-by-step explanation:
Given that,
First side of a triangle = 3x+8
Second side of a triangle = 2x²-4x+5
The perimeter of the triangle = 4x²+2x-10
We need to find the expression for the third side. Let the third side b s.
Perimeter = Sum of all sides
4x²+2x-10 = 3x+8 + 2x²-4x+5 +s
4x²+2x-10 = 2x²-x+13+s
s = 4x²+2x-10- (2x²-x+13)
= 2x²+3x-23
So, the third side will be 2x²+3x-23.
At a school cafeteria a cold lunch costs $1.80, and a hot lunch costs $3.00. During one school year a school year a teacher spent a total of $288.60 on cold lunches and hot lunches. The number of cold lunches the teacher bought was 1 fewer than twice the number of hot lunches the teacher bought. Which system of equations can be used to find c, the number of cold lunches, and h, the number of hot lunches, the teacher taught during the school year?
Answer:
System of Equations is given as:
c = 2h - 1...... Equation 1
1.8c + 3h = 288.60....Equation 2
Step-by-step explanation:
Let us represent
The number of Cold lunch = c
The number of Hot lunch = h
The number of cold lunches the teacher bought was 1 fewer than twice the number of hot lunches the teacher bought.
Hence:
c = 2h - 1
At a school cafeteria a cold lunch costs $1.80, and a hot lunch costs $3.00. During one school year a school year a teacher spent a total of $288.60 on cold lunches and hot lunches.
Hence:
$1.80 × c + $3.00 × h = $288.60
1.8c + 3h = 288.60....Equation 2
The system of equations can be used to find c, the number of cold lunches, and h, the number of hot lunches, the teacher taught during the school year is given as:
c = 2h - 1...... Equation 1
1.8c + 3h = 288.60....Equation 2
The system of equations that can be used to calculate the number of hot and cold lunches is [tex]\mathbf{1.80c +3.00h = 288.60}[/tex] and [tex]\mathbf{c = 2h - 1}[/tex]
Let h represents hot lunch, and c represents cold lunch.
So, we have:
[tex]\mathbf{1.80c +3.00h = 288.60}[/tex]
[tex]\mathbf{c = 2h - 1}[/tex]
Substitute [tex]\mathbf{c = 2h - 1}[/tex] in [tex]\mathbf{1.80c +3.00h = 288.60}[/tex]
[tex]\mathbf{1.80(2h -1) +3.00h = 288.60}[/tex]
Expand
[tex]\mathbf{3.60h -1.80 +3.00h = 288.60}[/tex]
Collect like terms
[tex]\mathbf{3.60h +3.00h = 288.60 + 1.80}[/tex]
[tex]\mathbf{6.60h = 290.4}[/tex]
Divide both sides by 6.60
[tex]\mathbf{h = 44}[/tex]
Substitute 44 for h in [tex]\mathbf{c = 2h - 1}[/tex]
[tex]\mathbf{c = 2(44) - 1}[/tex]
[tex]\mathbf{c = 83}[/tex]
Hence, the system of equations that can be used to calculate the number of hot and cold lunches is [tex]\mathbf{1.80c +3.00h = 288.60}[/tex] and [tex]\mathbf{c = 2h - 1}[/tex]

Alex constructs a scatter plot. He realizes that he needs to add one more point, which will be an outlier. Which of the ordered pairs does he still need to plot? (14,2) (2,12) (18,10) (10,6)
Answer:
(14,2)
Step-by-step explanation:
Have took the test
(14,2) is an outlier of the constructed scatter plot.
What is scatter plot?A scatter plot is a set of points plotted on a horizontal and vertical axes. Scatter plots are important in statistics because they can show the extent of correlation, if any, between the values of observed quantities or phenomena (called variables).
Given that, Alex constructs a scatter plot. He realizes that he needs to add one more point,
As we know If one point of a scatter plot is farther from the regression line than some other point, then the scatter plot has at least one outlier. If a number of points are the same farthest distance from the regression line, then all these points are outliers.
Here, When we will plot each of the points, and we will find that (14, 2) is the furthest away from the scatter
Hence, (14,2) is an outlier of the constructed scatter plot.

Length of the rectangular sand box is given by the function,
F(x) = 3x³ + 6x - 2
Width of the sand box is represented by the function,
W(x) = 2x² - 4
Area function for the sand box will be,
Area of a rectangle = Length × Width
F(x) × W(x) = (3x³ + 6x - 2)(2x² - 4)
= 2x²(3x³ + 6x - 2) - 4(3x³ + 6x - 2)
= 6x⁵+ 12x³ - 4x²- 12x³- 24x + 8
= 6x⁵- 4x²- 24x + 8
Therefore, Area function will be represented by a polynomial degree of 5.
Option B will be the answer.

Ulio is running in a 13.1-mile race. There are water stops every 2.75 miles along the route from the beginning of the race. What is the distance between the last water stop and the end of the race? Enter your answer in the box.
Answer:
2.1 miles
Step-by-step explanation:
Given that :
Total distance = 13.1 miles
Distance between each water stop = 2.75 miles
Distance between last water stop and end of the race
We need to find the maximum number of water stops :
Total miles / distance between water stops
13.1 / 2.75
= 4.763
Maximum number of water stops = 4
Distance to last water stop = 4 * 2.75 = 11 miles
Hence, distance between last water stop and end of Race :
Total miles - distance to last water stop
13.1 miles - 11 miles
= 2.1 miles
write the equation of a line perpendicular to 2y+x=4 and passes through the point (2,1)
Answer:
Por favor, dame una captura de pantalla de la pregunta No entiendo esto gracias
Answer:
[tex]-2x+y=-3[/tex]
Step-by-step explanation:
Recall perpendicular lines have negative-reciprocal slopes. Since the equation [tex]2y+x=4[/tex] has a slope of [tex]-\frac{1}{2}[/tex] ([tex]y=-\frac{1}{2}x+2[/tex]), any line perpendicular to it will have a slope of [tex]-\frac{1}{-\frac{1}{2}}=2[/tex].
Therefore, we have the line:
[tex]y=2x+b[/tex] where [tex]b[/tex] is the y-intercept.
We can plug in the point it passes through to find the final equation:
[tex]1=2(2)+b,\\b=1-4,\\b=-3[/tex].
Therefore, the equation of the line perpendicular to [tex]2y+x=4[/tex] that passes through the point [tex](2, 1)[/tex] is:
[tex]y=2x-3[/tex] (slope-intercept form)
However, since the initial line given is in standard form, re-write this equation to standard form:
[tex]y=2x-3,\\y-2x=-3,\\\fbox{$-2x+y=-3$}[/tex].
