Answer:
[tex]22\ km[/tex]
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]
[tex]22=Total\ distance[/tex]

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! :)

Answer:

Step-by-step explanation:
∠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

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.

Find an expression which represents the sum of (-8x+7y)(−8x+7y) and (2x-2y)(2x−2y) in simplest terms.
Answer:
Step-by-step explanation:
(-8x+7y)(-8x+7y)+(2x-2y)(2x-2y)
=64x²-56xy-56xy+49y²+(4x²-4xy-4xy+4y²)
=64x²-112xy+49y²+4x²-8xy+4y²
=68x²-120xy+53y²
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

A prism is filled with 28 cubes with 1/2 unit lengths. What is the volume of the prism in cubic units?
Answer:
3.5 cubic units
Step-by-step explanation:
First, find the volume of one cube
Use the cube volume formula, V = s³, where s is the side length
V = (1/2)³
V = 1/8 cubic units
Now, find the volume of the prism by multiplying this by 28, since there are 28 cubes
28(1/8)
= 3.5
So, the volume of the prism is 3.5 cubic units
2(x+2)-7=6x-4(1+x) solve for x
Answer:
x has no solution
Step-by-step explanation:
2x+4-7=6x-4-4x
2x-3=2x-4
-3=-4
Answer:
No solution
Step-by-step explanation:
2(x+2) -7 = 6x - 4(1+x) (Distribute 1st)
2x + 4 - 7 = 6x - 4 - 4x
2x - 3 = 2x - 4 (Combine like-terms)
2x - 2x = -4 + 3
0 = -1
No solution

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
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
