Work out the value of x
Answers
Answer:
67.5°
Step-by-step explanation:
Given, 90° + x + 3x = 360°
4x = 360° - 90°
4x = 270°
x = 67.5°
Answer:
67.5
Step-by-step explanation:
[tex]3x + x + 90 = 360[/tex]
[tex]4x + 90 = 360[/tex]
[tex]4x = 360 - 90[/tex]
[tex]4x = 270[/tex]
[tex]x = 270 \div 4 = 67.5[/tex]

2100 students were surveyed about whether they went to the Homecoming Dance and the Prom. 1470 students went to the Homecoming Dance. 570 students went to Prom only. 360 students went to both the Homecoming Dance and Prom. P (Went to Prom or None).
Answers
Answer and Step-by-step explanation: The problem can be solved by using a Venn Diagram.
A Venn Diagram shows the relation between a collection of different sets.
The figure below shows:
1) Students who went only to the Homecoming = 1110
2) Students who went only to the Prom = 570
3) Students who went to both = 360
4) Students who went to none = 60
The question asks for the probability of students who went to Prom or None.
Probability of Prom = [tex]\frac{570}{2100}[/tex]
Probability of None = [tex]\frac{60}{2100}[/tex]
As it is asking for "OR", use the "or rule", i.e., add the probabilities:
P(Prom or None) = [tex]\frac{570}{2100}+\frac{60}{2100}[/tex]
P(Prom or None) = [tex]\frac{630}{2100}[/tex]
P(Prom of None) = 0.3
The probability of a student had went to Prom or none of them is 0.3 or 30%.
What is the radius of a hemisphere with a volume of 10470 in?, to the nearest tenth
of an inch?
Answers
Answer:
r ≈ 17.1 in
Step-by-step explanation:
Volume Of Hemisphere: 10,470
Volume Of Sphere: 20,940
Volume Of A Sphere: V = 4/3π(r)^3
20,940 = (4.1887902)r^3 [Evaluate 4/3π In Calc]
20940 = (4.1887902)r^3
4.1887902 4.1887902
4999.0567625 = r^3
∛4999.0567625 = ∛r^3
17.0986841 = r
Final Answer:
r≈17.1 in

The math club has 12 members. Each member pays monthly dues of $13.20. On the first day of the month, 8 members paid their dues. The remaining members paid their dues on the second day of the month. How much money was collected in dues on the second day of the month?
Answers
Answer: $52.80
Step-by-step explanation:
Number of members = 12
Monthly due per member = $13.20
Total amount expected = $13.20 × 12 = $158.40
On the first day of the month, 8 members paid their dues. Total amount paid will be:
= 8 × $13.20
= $105.60
The money that was collected in dues on the second day of the month will be:
= $158.40 - $105.60
= $52.80

3x - 2y = 1
Answers
2x+y=10 for y:
2x+y=10
2x+y+−2x=10+−2x
(Add -2x to both sides)
y=−2x+10
Step: Substitute−
2x+10 for y in 3x−2y=1:
3x−2y=1
3x−2(−2x+10)=1
7x−20=1
(Simplify both sides of the equation)
7x−20+20=1+20
(Add 20 to both sides)
7x=21
7x=21
_ _
7 7
(Divide both sides by 7)
x=3
Step: Substitute
3 for x in y=−2x+10:
y=−2x+10
y=(-2)(3)+10
y=4
(Simplify both sides of the equation)
Answer:x=3 and y=4
