What is the surface area of the cone in terms of π?
A cone. The diameter of the base is 8 meters and the slant height of the cone is 15 meters.
Answer:
The surface area of the cone is;
68 π m^2
Step-by-step explanation:
Here, we want to get the surface area of the cone
Mathematically, we have this as ;
S.A = π(r^2 + rl)
where r is the radius and l is the slant height
We are given the diameter, but the radius is half of this
d = 8
r = d/2 = 8/2 = 4 m
l = 13 m
S.A = π(4^2 + 4(13))
= π(16 + 52) = 68 π m^2
Which expression is equivalent to 24x8y 4.5 ? Assume X=and y> 0. 128x+y 473 2x2y 4y2 43 4xy? 4/3x.
Answer:
D. [tex]\frac{\sqrt[4]{3x^2}}{2y}[/tex]Step-by-step explanation:
[tex]\sqrt[4]{\frac{24x^6y}{128x^4y^5} }[/tex] = [tex]\sqrt[4]{\frac{3x^2}{16y^4}}[/tex] = [tex]\sqrt[4]{\frac{3x^2}{(2y)^4}}[/tex] = [tex]\frac{\sqrt[4]{3x^2}}{2y}[/tex]Correct choice is D
[tex]\frac{\sqrt[4]{3x^2}}{2y}[/tex] is the simplification of the given expression.
What is simplification?Simplifying procedures is one way to achieve uniformity in job efforts, expenses, and time. It reduces diversity and variation that is pointless, harmful, or unneeded. Parenthesis, exponents, multiplication, division, addition, and subtraction are called PEMDAS. The order of the letters in PEMDAS informs you what to calculate first, second, third, and so on, until the computation is finished, given two or more operations in a single statement.
It is given an expression [tex]\sqrt[4]{\frac{24x^6y}{128x^4y^5} }[/tex]
Simplifying the given expression using the PEMDAS technique,
[tex]\sqrt[4]{\frac{24x^6y}{128x^4y^5} }\\\\\sqrt[4]{\frac{3x^2}{16y^4} }\\\\\frac{\sqrt[4]{3x^2}}{2y}[/tex]
Therefore, the simplified value of the given expression is [tex]\frac{\sqrt[4]{3x^2}}{2y}[/tex]. Thus, the option D is correct.

This is because we are given an Isosceles Triangle. Isosceles Triangles always have 2 legs/sides that are the same length, and because those two sides have the same length, it means their base angles have the same value as well.
So, Since the angles LKM and KML are the base pairs of this Isosceles Triangle, they are equal to each other.

A gardening store ordered 5,710 potted plants last year. This year, the store ordered 10% fewer potted plants. How many potted plants were ordered this year?
Answer:
5319
Step-by-step explanation:
There are two ways that the answer can be determined
Method 1
Determine 10% of 5710. the answer gotten is subtracted from 57100.1 x 5710 = 571
5710 - 571 = 5319
Method 2
If the plants planted this year are 10% fewer, the plants this year are (100% - 10%) 90% of last year's plant
90% x 5710
0.9 x 5710 = 5319
Running at a constant rate, Miguel ran 12 miles in a time of 120 minutes. How many minutes does it take Miguel to run 6 miles?
Answer:
20
Step-by-step explanation:
120/6
Answer:
60 minutes
Step-by-step explanation:
First, lets write the problem into an equation
12 miles/120 minutes = 6 miles/x minutes
Then, we solve
12/120 = 6/x
12x = 720
x = 60
Therefore, your answer is 60 minutes

The circumference of a circular garden is 119.32 feet. What is the radius of the garden? Use 3.14 for t and do not round your answer.
Answer:
r = 19 ft
Step-by-step explanation:
Circumference, C is given as 119.32 ft
Circumference of a circle is given by the formula, 2πr
This means that,
C = 2πr, we're told to assume that π = 3.14
So therefore,
119.32 = 2 * 3.14 * r
r = 119.32 / 6.28
r = 19 ft

Optional question for brainliest: The quotient of a number y and - 3.6 is less than 6.5
Answer: Expert Answer quotient is a mathematical operation requiring two things, i.e. the quotient of a and b is a ÷ b, or a/b. In this case, the problem mentions y / (-3.6) and goes on to say < 6.5. So you have this inequality: y / (-3.6) < 6.5. or equivalently y > - 117/5.

A camper is flying a kite at the end of a string 250 feet long. If they look up to
the kite at an angle of 43 degrees, what is the approximate height of the kite? (Round
your answer to the nearest foot.).
hypotenuse is 250 feet.
base angle is 43 degrees.
trignometery here I come!
Since we must find the height, aka adjacent side of right triangle, and we have the given hypotenuse
We shall use the sine!
sinθ is sin43
sin43 = A/H = x/250
multiply both sides by 250
250 (sin43) = x

Luis has some nickels, dimes, and quarters. The value of all of the coins, in cents, is represented with the expression shown.

Which part of the expression represents the number of quarters that Luis has?
A. x+2
B. 10x
C. 3x+1
D. 25(3x+1)
B.
10.
C
3.2 +1
D.
25 (3x + 1)
Answer:
The part of the expression that represents the number of quarters is;
D. 25·(3·x + 1)
Step-by-step explanation:
From the question, we have;
The values of the coins Luis has = Nickels, Dimes and quarters
The expression that represents the value of all the coins in cents is given as follows;
5(x + 2) + 10·1 + 25·(3·x + 1)
The value of a nickel = 5 cents
The value of a dime = 10 cents
The value of a quarter = 25 cents
Therefore, the part of the expression representing the number of quarters Luis has, has 25 as a factor
Therefore, the part of the expression that represents the number of quarters = 25·(3·x + 1).

Which is the solution to the system of equations?2x+y=7 and 3x−4y=5
Answer:
X = 3, Y = 1.
Step-by-step explanation:
X = 3 and Y = 1, because 2 times 3 equals 6, and 6 plus 1 equals 7. So that's for the first one, but now we need to make sure that it's the same value for the other equation. 3 times 3 equals 9, 4 times 1 equals 4, and 9 minus 4 equals 5. So X = 3, and Y = 1. Hope this helped :D
Tyrone practices the piano for 120 min each week. Amina practices the piano 45% of the time that Tyrone practices each week. How many minutes does Amina practice the piano each week?
Answer:
Amina practices the piano for 54 minutes each week.
Step-by-step explanation:
45% * 120min = 0.45 * 120min = 9/20 * 120min = 9 * 6min = 54min
If there are 60 seconds in an minute, 60 minutes in an hour, 24 hours in a day, and 7 days in a week, how many seconds are in a week? Hint: Use a calculator to solve this problem.James and Kelly have $10 to spend at a grocery store. If they get 3 avocados which cost $1 each, 4 tomatoes which cost a total of $2 for all 4, and two loaves of bread which cost $2 each, how much change will James and Kelly receive after their purchase?
Answer:
Part a) 60 seconds in a minute, 60 minutes in an hour, 24 hours in a day, and 7 days in a week, how many seconds are in a week
60x60=3600 x 24= 86400 x 7= 604800
So 604,800 seconds in a week
Part b) James and Kelly have $10 to spend at a grocery store. If they get 3 avocados which cost $1 each, 4 tomatoes which cost a total of $2 for all 4, and two loaves of bread which cost $2 each, how much change will James and Kelly receive after their purchase?
So 3 x 1= $3
+ $2
2 x 2= $4
3+2+4= $9
10-9= $1
So they'll get back $1

Ariana bought 5 dozen pears at $36 per dozen . She discovered that 7 were rotten and she sold the rest at $4.50 each . Calculate the profit or loss she made on the sale of all the good pears . don't send in file okay
Step-by-step explanation:
1 dozen = 12 pears
12 pears = $36
1 pear = 36/12 = $3
Total Cost of Pears = No. of pears x price of 1 pear
= (5x12) x 3
= 60 x 3
= $180
Sale of Pears = Price per pear x (Total Pears bought - Rotten Pears)
= $4.50 x (5x12-7)
= $4.50 x 53
= $238.50
Profit/Loss = Sale of Pears - Total Cost of Pears
= $238.50 - $180
= $58.50
Ariana made a profit of $58.50.
Answer:
$58.5 (profit)
Step-by-step explanation:
Ariana bought 5 dozen pears at $36 per dozen.
The value of 1 dozen = $ 36
Her buying amount = $36 * 5 = $180
The value of 1 pear = $ 36/12
= $3
The value of 7 pears= $3 * 7 = $21
She sold the remaining (53) at $4.50 each.
Her, selling amount = $4.50 * 53
= $238.50
Her profit amount = selling amount - buying amount
= $238.50 - $180
= $58.5
