George tells you that when variables are in the denominator, the equation
2/3+5/x=8/9 becomes unsolvable. George explains, "There is a value for x that makes the denominator zero, and you can't divide by zero." Demonstrate to George how the equation is still solvable and explain your reasoning.
Answer:
X can equal 22.5
Step-by-step explanation:
I've set up the equation below:
[tex]\frac{2}{3} +\frac{5}{x} =\frac{8}{9}[/tex]
With this equation, as any addition equation goes, we assume it to be like this:
A + B = C
so
C - A = B
that means,
[tex]\frac{8}{9} -\frac{2}{3} =\frac{5}{x}[/tex]
The easiest thing to do is to make 2/3 have the same denominator as 8/9, we do this by...
[tex]\frac{2}{3} *\frac{3}{3} = \frac{6}{9} \\[/tex]
So...
[tex]\frac{8}{9} -\frac{6}{9} =\frac{2}{9} =\frac{5}{x}[/tex]
We now know that 5 over x equals 2 over nine. We can determine x by cross multiplying as follows:
[tex]\frac{5}{x} =\frac{2}{9} \\2x = 45\\x=22.5[/tex]
So, x is 22.5, making the equation indeed solvable.

Answer:
If figures are similar, corresponding sides have same ratio.
Similar polygonsSide IJ x is corresponding with QR, and side HK with PS:
x/6.5 = 25.5/8.5x = 6.5*3x = 19.5 Similar trianglesRatio of corresponding sides:
x/7 = 18/6x = 7*3x = 21In two similar triangles find the ratio of corresponding sides if the areas are 50cm²and 98cm²
Answer:
5:7
Step-by-step explanation:
The areas of two triangles are 50cm²and 98cm².
We need to find the ratio of corresponding sides. It can be calculated as follows :
[tex]\dfrac{s_1}{2_2}=\sqrt{\dfrac{A_1}{A_2}} \\\\=\sqrt{\dfrac{50}{98}}\\\\=\sqrt{\dfrac{25}{49}}\\\\=\dfrac{5}{7}[/tex]
So, the ratio of corresponding sides are 5:7.

Gerald has a bag of 10 colored balls: 3 green, 3 red, and the rest yellow. He randomly draws two balls, one at a time without replacement. Find the probability of drawing at least one yellow ball.
Answer:
2/3
Step-by-step explanation:
Probability is the ratio of the number of possible outcome to the number of total outcome.
Given that there are 10 balls of which 3 green, 3 red, and the rest yellow
Number of yellow balls = 10 - 3 - 3 = 4
Probability of picking a;
Green ball = 3/10
Red ball = 3/10
Yellow ball = 4/10
If two balls are picked without replacement, the probability that one is at least yellow will be
YR RY YG GY YY
= 4/10*3/9 + 3/10*4/9 + 4/10*3/9 + 3/10*4/9 + 4/10*3/9
=12/90 *5
= 2/3
Look at the two-dimensional net shown.
A rectangular pyramid. The rectangular base has a length of 10 meters and height of 3 meters. 2 triangular sides have a base of 10 meters and height of 6.4 meters. 2 triangular sides have a base of 3 meters and height of 8 meters.
Which statements are true?
Check all that apply.
The solid formed by the net will be a rectangular pyramid.
The solid formed by the net will be a square pyramid.
All four triangular faces have an area of 12 m2.
There are two sets of opposite congruent triangular faces.
The base has an area of 30 m2.
Answer: Pyramid A: Base is rectangle with length of 10 meters and width of 20 meters.
Pyramid B: Base is square with 10 meter sides.
Heights are the same.
Step-by-step explanation: The volume of pyramid A is TWICE the volume of pyramid B.
If the height of pyramid B increases to twice the of pyramid A, (from 10m to 20m),
V of square pyramid = (10m)² * (10*2)/3 = 100m² * 20m/3 = 100m² * 6.67m = 666.67 m³
The new volume of pyramid B is EQUAL to the volume of pyramid A.

A mountain climber took 2 minutes to rappel down 60 feet. Which equation shows the correct calculation to show his movement per minute?
Answer:
–60 ÷ 2 = –30
Step-by-step explanation:
Calculation to determine the equation that shows the correct calculation to show his movement per minute
Using this formula
Speed rate = Distance / Time
Where,
Distance=-60 ft
Time =2 min
Let plug in the formula
Speed rate = -60 ft /2 min
Speed rate = -30
Based on the information given we were told that the climber rappel DOWN which is why the distance was negative.
Therefore the equation that shows the correct calculation to show his movement per minute is –60 ÷ 2 = –30

On one day a pet store sells 2 birds 6 gerbils 3 fish and 3 hamsters whats the data and relative frequency as a percent?
Answer:
Birds [tex]F_b=14.3\%[/tex]
Gerbils [tex]F_g=42.9\%[/tex]
Fish [tex]F_f=21.4\%[/tex]
Hamsters [tex]F_h=21.4\%[/tex]
Step-by-step explanation:
From the question we are told that:
Sales
Number of birds [tex]n_b=2[/tex]
Number of gerbils [tex]n_g=6[/tex]
Number of fish [tex]n_f=3[/tex]
Number of hamsters [tex]n_h=3[/tex]
Generally the frequency for birds [tex]F_b[/tex] is mathematically given b
[tex]F_b=\frac{n_b}{n}*100[/tex]
[tex]F_b=\frac{2}{14}*100[/tex]
[tex]F_b=14.3\%[/tex]
Generally the frequency for Gerbils [tex]F_g[/tex] is mathematically given b
[tex]F_g=\frac{n_g}{n}*100[/tex]
[tex]F_g=\frac{6}{14}*100[/tex]
[tex]F_g=42.9\%[/tex]
Generally the frequency for fish [tex]F_f[/tex] is mathematically given b
[tex]F_f=\frac{n_f}{n}*100[/tex]
[tex]F_f=\frac{3}{14}*100[/tex]
[tex]F_f=21.4\%[/tex]
Generally the frequency for fish [tex]F_h[/tex] is mathematically given b
[tex]F_h=\frac{n_h}{n}*100[/tex]
[tex]F_h=\frac{3}{14}*100[/tex]
[tex]F_h=21.4\%[/tex]

Answer:
112 cm^2
Step-by-step explanation:
Area of a rhombus is equal to half of the product of the diagonals, so it is 14 * 2 * 8 / 2 = 14cm * 8cm = 112 cm^2.
Other point of view: It is the sum of areas of two triangles of area 14*8/2. So the area is 14*8.

On Wednesday 72% of the customers who bought gas at a gas station also bought a hot dog. There were 25 customers in all who bought gas.
Answer:
18 People bought hot dogs
Step-by-step explanation:
The question is not complete, but I’m assuming you need the number of people who bought hot dogs.
25 customers bought gas.
72% of them also bought a hot dog.
So thE number of customers who bought hot dogs are 72% of 25
=> 72/100 * 25
=> 0.72 * 25
= 18 people

The measure of ∠B is 31.6 .
What is trigonometric ratio?Trigonometric ratios are the ratios of the length of sides of a triangle.
These ratios in trigonometry relate the ratio of sides of a right triangle to the respective angle.
The basic trigonometric ratios formulas are given below,
sin θ = Perpendicular/Hypotenuse
cos θ = Base/Hypotenuse
tan θ = Perpendicular/Base
sec θ = Hypotenuse/Base
cosec θ = Hypotenuse/Perpendicular
cot θ = Base/Perpendicular
According to the question
In right angle triangle ACB
Base BC= 22.9
Perpendicular AC = 14.1
now , using trigonometric ratio
tan ∠B = [tex]\frac{AC}{BC}[/tex]
tan ∠B = [tex]\frac{14.1}{22.9}[/tex]
∠B = [tex]tan^{-1} 0.615[/tex]
∠B = 31.6
Hence, The measure of ∠B is 31.6 .
