In a group of students, 50% like tea, 70% like coffee, 10% don't like both and 120 like both. By using Venn diagram, find the total number of students.
Answer:
Since 10% like neither, then 90% must like tea(T), coffee(C) or both(B). So what % like both? That % would have to be deducted from both the tea and coffee likers to arrive at tea only (TO), coffee only (CO) and those liking both and the three would have to sum to 90%, since 10% like neither. So whatever % the 120 represents it must be deducted from both the tea and coffee likers. I don’t know how to add graphics but in equation form
50-x + 70-x + x + 10 = 100, 130-x = 100, -x = -30, X = 30%,
120/30% = 400, 50%(T)-30%(B)=20%(TO) or 80, 70%-30%=40% or 160, 30% or 120, and 10% or 40
80+160+120+40=400
Answer:
Step-by-step explanation:
50% 70% 10%
like tea like coffee don't like both
100%-10% =90%
like coffee,tea or both
50% + 70% =120% - 90% = 30%
like tea + like coffee = - = like both
LIKE BOTH 30%=`120
means 1%=4
100%=400

5. INDIRECT MEASUREMENT A lighthouse casts a 128-foot shadow. A nearby lamppost that
measures 5.25 feet casts an 8-foot shadow.
Write a proportion that can be used to determine the height of the lighthouse. What is the height of the lighthouse?
MGSE9-12.G.SRT 5
b. 5.25
a. 1285.25; 195 ft
X 128
8 ; 84 ft
128
c. 5.25" 8 ; 672 ft
X 128
d. 3 5.25; 195 ft
Using proportions, it is found that the height of the lighthouse is of 84 ft.
This question is solved by proportions, using a rule of three.For a height of 5.25 feet, the shadow is of 8 feet. What is the height when the shadow is of 128 feet?The rule of three is:
5.25 feet - 8 feet
x feet - 128 feet
Applying cross multiplication:
[tex]8x = 5.25(128)[/tex]
[tex]x = \frac{5.25(128)}{8}[/tex]
[tex]x = 84[/tex]
The height of the lighthouse is of 84 ft.

Answer:
9
Step-by-step explanation:
To calculate the value of x we must first understand the total value of all angles in a triangle.
Sum of all angles in a triangle = 180 degrees
That said, we need to write an equation for the total number of degrees in the triangle and solve for x
This will be as follows:
(13x+2)+(5x-7)+(3x-4)=180
The we combine the like terms. This will be as follows:
(13x+5x+3x)+(2-7-4)=180
Simplify further to get
21x-9=180
Simplify further by collecting all like terms on one side of the equal. This will entail the addition of 9 on each side of the equal sign as follows:
21x-9+9=180+9
you will find 21x=189
Simplify further by dividing both sides of the equal sign by 21 to solve for x
21x/21=189/21
Therefore x=9

What is the exponential form of the logarithmic equation?
4=log0.7(0.2401)
The exponential form of the logarithmic equation 4 = [tex]log_{0.7} (0.2401)[/tex] is
0.7⁴ = 0.2401
4 = [tex]log_{0.7} (0.2401)[/tex]
The exponential form of the logarithmic equation can be represented below:
Using logarithm rules,
logₐ b = x
Can be represented in exponential form as follows:
aˣ = b
Therefore,
4 = [tex]log_{0.7} (0.2401)[/tex]
using the logarithm rule described above can be represented in exponential form as follows:

what multiplication fact can you double to find 4 x 7?
Answer:
2 x 7
Step-by-step explanation:
4 x 7 = 28
Since you want doubled, we have to half to find start.
28/2 = 14
Only solid equation that equals 14 is 2 x 7
And since 4 is a double of 2, the answer checks out
The multiplication fact that can be doubled to find 4 x 7 is
2 x 7.
What is an expression?An expression is a way of writing a statement with more than two variables or numbers with operations such as addition, subtraction, multiplication, and division.
Example: 2 + 3x + 4y = 7 is an expression.
We have,
4 x 7 = 28
Now,
The multiplication of 2 x 7 = 14.
If 2 x 7 is double we get,
2 x (2 x 7) = 2 x 14 = 28
Thus,
The multiplication fact is 2 x 7.

Step-by-step explanation:
The triangle is isosceles. The measure of the two internal angles J and K are equal; The misure of the external K angle (2) is half a circle minus the internal K (1). The internal angle in R is calculated by difference between 180 and twice the internal K angle (1).
