Working alone, it takes Scott 16 minutes to inflate twenty balloons, Ashley can inflate the same twenty balloons in 15 minutes. Find how long it would take them if they worked together.
Answer:
7.74 minutes
Step-by-step explanation:
Scott's rate = 20 /16 = 1.25
Ashley's rate = 20 / 15 = 1.333
Combined rate = (1.25 + 1.3333) = 2.583333
Hence, time it will take to inflate 20 balloons :
Rate = number of balloons / time taken
2.583333 = 20 / time taken
Time taken = 20 / 2.583333
Time taken = 7.7419
It will take them approximately 7.7 minutes to inflate 20 balloons

∠A and \angle B∠B are vertical angles. If m\angle A=(2x+26)^{\circ}∠A=(2x+26) ∘ and m\angle B=(3x+21)^{\circ}∠B=(3x+21) ∘ , then find the measure of \angle B∠B.
Answer:
36degrees
Step-by-step explanation:
If m<A and m<B are vertical angles, hence m<A = m<B (vertical angles are equal)
Given the following
m<A = (2x+26)°
m<B = (3x+21)°
Equating both expressions
2x + 26 = 3x + 21
2x - 3x = 21 - 26
-x = -5
x = 5
Get the measure of m<B
m<B = (3x+21)°
m<B = 3(5) + 21
m<B = 15+21
m<B = 36degrees
Hence the measure of angle B is 36degrees

Step-by-step explanation:
One is given the following information:
[tex]10\frac{1}{1}[/tex] km were covered on Thursday[tex]10\frac{1}{1}[/tex] km were covered on FridayOne is asked to find the total distance covered on both of these days. In order to do so, one must remember in a fraction, any number over (1) is equal to the numerator (number over the fraction bar). Thus one can form the following equation:
[tex](Thursday)+(Friday) = Total\ distance[/tex]
Substitute,
[tex](Thursday)+(Friday) = Total\ distance[/tex]
[tex](10\frac{1}{1})+(10\frac{1}{1}) = Total\ distance[/tex]
Simplify,
[tex](10\frac{1}{1})+(10\frac{1}{1}) = Total\ distance[/tex]
[tex](10+1)+(10+1) = Total\ distance[/tex]
[tex](11)+(11)=Total\ distance[/tex]
[tex]11+11=Total\ distance[/tex]

Find the volume of the cone round your answer to the nearest tenth
Answer:
209.43951 round to the nearest tenth is 209.44
Step-by-step explanation:
A cone with a base radius of 5 units and a height of 8 units has a volume of 209.44 cubed units.
If a cone has a flat bottom, meaning the height and radius meet at right angles, then this formula can be used to find of volume ('V') of that cone (also know as a right circular cone):
V = 1/3(PI*r squared * h )
The volume of a cone can be calculated by taking one-third of the result of the radius squared, multiplied by the height, multiplied by the mathematical constant pi.
Here is a step-by-step case that illustrates how to find to volume of a cone with a radius of 2 feet and a height of 3 feet. Note that in order to save space (and because pi cannot be determine precisely) a limited number of decimal places are used, the symbol ~ denotes that this answer is an approximation.
V = 1/3(pi * r^2 * h)
= 1/3(pi * 2^2 * 3)
= 1/3(pi * 12)
= 1/3(37.7)
~ 12.6 cubic feet

what does 2(3y – 4) =
Let's use the distributive property to simplify this problem.
The first thing we want to do is change the minus to plus a negative.
Now distribute or multiply the 2 by each of the terms inside the parentheses.
So we get 2(3y) + 2(-4) and this simplifies to 6y + -8
Note that if you wrote your answer as 6y - 8, it means the same thing.
find the inverse of the radical function y=-5+2/5√x
Answer:
y = (25/4)(x + 5)^2
Step-by-step explanation:
1. Interchange x and y, obtaining: x = -5 + (2/5)√y
2. Solve this result for y: x + 5 = (2/5)√y
Squaring both sides, we get (x + 5)^2 = (4/25)y
Multiplying both sides by (25/5) cancels out the (4/25) coefficient:
y = (25/4)(x + 5)^2 This is the inverse of the given function.

A baker made 6 pounds of dough. He used 8 9 of the dough to make sandwich rolls. How much of the dough is left over?
Answer:
2/3 pound of dough is left
Step-by-step explanation:
Amount of dough available = 6 pounds
The amount used in making sandwich rolls = 8/9 of the total amount
= [tex]\frac{8}{9} \times6 = 5\frac{1}{3} pounds[/tex]
Therefore, amount of dough left over [tex]= 6- 5\frac{1}{3} = \frac{2}{3} \\[/tex]
Hence, 2/3 pounds of dough is left

A square pyramid has side lengths each measuring 8 centimeters. The height of the pyramid is 3 centimeters What is the lateral area of the pyramid?
20 square centimeters
64 square centimeters
80 square centimeters
84 square centimeters
Answer:
C. 80 square centimeters
Step-by-step explanation:
Edge 2021
The lateral surface area of the given square pyramid is 80 cm².
What is lateral surface area?The lateral surface of an object is its entirety, excluding its base and top (when they exist).
Boundary - layer surface zone equals lateral surface area. This is to be contrasted from the total surface area, which includes the lateral surface area along with the base and top regions.
Given that, a square pyramid has side lengths each measuring 8 centimeters.
The height of the pyramid is 3 centimeters.
The lateral area of a square pyramid = 2al = 2a√[(a²/4) + h²]
= 2×8√[(8²/4) + 3²]
= 16√[(64/4) + 9]
= 16√[16 + 9]
= 16×5
= 80 cm²
Therefore, the lateral area of the pyramid is 80 cm².

2+5x-2x=6x+3x-7 help
Answer:
The value of x in this equation is 3/2.
Step-by-step explanation:
First, let's take the original equation:
2 + 5x - 2x = 6x + 3x - 7
In order to solve for x, we must isolate the variable x on one side of the equation, and the rest of the numbers on the other side of the equation. So we take: 2 + 5x - 2x = 6x + 3x - 7 and use some of the properties of equality:
We start with 2 + 5x - 2x = 6x + 3x - 7 and see that we can minus 2 on both sides of the equation as highlighted below:
2 + 5x - 2x = 6x + 3x - 7
2 + 5x - 2x - 2 = 6x + 3x - 7 - 2
This simplifies the equation to 5x - 2x = 6x + 3x - 9.
Remember, we can arrange the equation like this along as we do on one side what we do on the other. Now, we have 5x - 2x = 6x + 3x - 9, and see that the rest of 6x and 3x needs to go on the left side of the equation. In order to do this, we can minus 6x from both sides of the equation as shown below:
5x - 2x = 6x + 3x - 9
5x - 2x - 6x = 6x + 3x - 9 - 6x
which then simplifies to 5x - 2x - 6x = 3x - 9. Now we can do the same thing by minus 3x from both sides of the equation.
5x - 2x - 6x = 3x - 9
5x - 2x - 6x - 3x = 3x - 9 - 3x
5x - 2x - 6x - 3x = -9
Now, we must simplify the left side of this equation by adding together the variable numbers 5x - 2x - 6x - 3x. This is shown below:
5x - 2x - 6x - 3x = -9
3x - 6x - 3x = -9
-6x = -9
Lastly, we can divide the number -9 by -6 to get the answer of what 1 x equals. This means -9/-6 = 3/2.
X is indeed equal to 3/2
Series:
Use the Arithmetic Series formula to calculate the sum:
-6+(-3)+0+ • • • + 162
(Hint: how many numbers are being added?)
Answer:
Step-by-step explanation:
The common difference is 3.
nth term = -6+(n-1)3
-6+(n-1)3 = 162
(n-1)3 = 168
n-1 = 56
n = 57
162 is the 57th term.
S₅₇ = 57×(a_1+a_{57})/2
= 57×(-6+162)/2
= 57×156/2
= 57×78
= 57×(-6+162)/2
= 4446

Answer:
7pi/theta = radius
Step-by-step explanation:
So we are using the arc length, central angle(in radians), and radius.
We know arc length, which is 7pi.
We don't know theta, which does not matter.
And finally, we don;t know radius, which is what we are looking for.
To find radius, we use:
arc length/theta=radius
Lets plug in our values:
7pi/theta=radius.
So the answer to the khan acadamy question is
7pi/∅
Here are some othr things that may help:
Radian * Radius = arc length
This solves for arc length
Here is another one:
Arc length/radius= radian
This solves for radians
Hope these help! :)
