jarak kota a ke kota b adalah 130 km Amir berangkat dari a pukul 8.15 menuju b dengan kecepatan rata-rata 50 km per jam Amir tiba di kota b pada pukul
Answer:
10:51
Step-by-step explanation:
Given that :
Distance from A to B = 130km
Departure time = 8 : 15
Average speed = 50 km/hr
Recall :
Speed = distance / time
Time = distance / speed
Time = (130 km) ÷ (50km/hr)
Time = 130 / 50
Time = 2.6 hours = 2 hours + (0.6 * 60) = 2 hours 36 minutes
Arrival time = (8:15) + (2 hours 36 minutes) = 10:51

help!!! please & explain if can:(
Answer:
x = 15
Step-by-step explanation:
AEB is a right angle, a right angle is 90 degrees
this means 5x+15 needs to equal 90
plug in 15 for x
5 x 15 + 15 = 90

A study done by researchers at a university concluded that 70% of all student-athletes in this country have been subjected to some form of hazing. The study is based on responses from 1800 athletes. What are the margin of error and 95% confidence interval for the study?
Answer:
Step-by-step explanation:
Given that:
The sample proportion [tex]\hat p = 0.70[/tex]
The sample size n = 1800
At 95% confidence interval level:
The level of significance = 1 - 0.95 = 0.05
Critical value: [tex]Z_{0.05/2} = Z_{0.025} = 1.96[/tex]
Thus, the Margin of Error E = [tex]Z_{\alpha/2} \times \sqrt{\dfrac{\hat p ( 1- \hat p)}{n}}[/tex]
[tex]= 1.96 \times \sqrt{\dfrac{ 0.70 ( 1-0.70)}{1800}}[/tex]
[tex]= 1.96 \times \sqrt{\dfrac{ 0.70 ( 0.30)}{1800}}[/tex]
[tex]= 1.96 \times \sqrt{\dfrac{0.21}{1800}}[/tex]
[tex]= 1.96 \times \sqrt{1.16666667\times 10^{-4}}[/tex]
the Margin of Error E = 0.021
At 95% C.I for the population proportion will be:
[tex]= \hat p \pm Z_{\alpha/2} \sqrt{\dfrac{\hat p(1- \hat p)}{n}}[/tex]
= 0.70 ± 0.021
= (0.70 - 0.021, 0.70 + 0.021)
= 0.679, 0.721)

The value of y varies directly with x. If x = 4, then y = 20.
What is the value of x when y = 60?
5
7
12
44
Answer: 12
Step-by-step explanation:
Since value of y varies directly with x, we introduce a constant, k which will give:
y = kx
If x = 4, then y = 20 we then calculate the value of k.
y = kx
20 = 4k
k = 20/4
k = 5
We then find the value of x when y = 60. This will be:
y = kx
60 = 5x
x = 60/5
x = 12
The value of x is 12 when y is 60
i just need the answers, u dont need to show ur work :)
Answer:
10 units
Step-by-step explanation:
Formula to find the distance between two points [tex](x_1,y_1)[/tex] and [tex](x_2,y_2)[/tex] is,
d = [tex]\sqrt{(y_2-y_1)^2+(x_2-x_1)^2}[/tex]
Distance between two points (0, -7) and (-6, 1) will be,
d = [tex]\sqrt{(0+6)^2+(-7-1)^2}[/tex]
= [tex]\sqrt{36+64}[/tex]
= [tex]\sqrt{100}[/tex]
= 10
Therefore, distance between the given points is 10 units.

4 pounds of sugar can make 8 batches of candy corn. How many pounds of sugar are needed if we want to make 12 batches of candy corn?
6
(4=8 so 8+4=12 which means, the answer is 2 because we can´t do 16, which is 8+8. But we can split the 4 in half since 4 is half of 8.)

Step-by-step explanation:
explain three situations under which the President of India can proclaim emergency
Answer:
The President can exercise his emergency powers in three types of emergencies: national emergency, state emergency, and financial emergency.
National Emergency is imposed by the President on request by the Prime Minister’s cabinet of ministers. Article 352 of the Indian Constitution states that an emergency can be called in the event of imminent danger to the national security due to armed rebellion, war or external aggression.
State Emergency is often referred to as President’s Rule. State emergency is declared under Article 356, in the event when the state government collapses and the constitutional machinery fails in a particular state. It can be imposed for a period of six months and can last only for three years with parliamentary consent required every six months. The Governor, the President’s representative in the state, governs the state under emergency in the name of the President.
Financial Emergency is imposed by the President if he reckons financial stability of the country is in danger. Article 360 empowers the President to declare this emergency on the condition that it would be approved by the Parliament within two months of its enforcement.

A popular dance club allows 29 customers to enter per hour. The club has to keep their occupancy below 600 at any time during the day. Currently, the club has 339 customers. If none of the customers leave, how many more hours, x, can the club continue to accept new customers?
Select the number line that includes the largest number of hours the club can continue to accept new customers without exceeding their occupancy.
Answer:
The club can continue to accept customers for 9.66 hours, after which they'll have exceeded 600.
Step-by-step explanation:
339 + 29h = 600
29h = 261
h = 9.66

What is the volume of the geometric solid produced by the triangle below
when it is rotated 360 degrees about the vertical axis YZ? *
Answer:
The volume of the geometric solid produced is 391 cubic cm ⇒ A
Step-by-step explanation:
When a right triangle is rotated about its vertical leg 360°, then it formed a cone its radius is the horizontal leg of the triangle and its height is the vertical lege of the triangle.
The rule of the volume of the cone is V = [tex]\frac{1}{3}[/tex] π r² h, where
r is the radius of its baseh is the length of its height∵ Triangle XYZ is rotated 360° about the vertical side YZ
∴ It formed a cone with a radius = XZ and a height = YZ
∵ [tex]\frac{YZ}{XZ}=tan(60)[/tex]
∵ YX = 6√3
∴ [tex]\frac{6\sqrt{3}}{XZ}=tan(60)[/tex]
∵ tan(60) = √3
∴ [tex]\frac{6\sqrt{3}}{XZ}[/tex] = √3
→ By using cross multiplication
∴ 6√3 = XZ(√3)
→ Divide both sides by √3
∴ 6 = XZ
∵ XZ = r and YZ = h
∴ r = 6 and h = 6√3
→ By using the rule of the cone above
∵ V = [tex]\frac{1}{3}[/tex] (π) (6)² (6√3)
∴ V ≅ 391 cm³
∴ The volume of the geometric solid produced is 391 cubic cm

Step-by-step explanation:
The tax rate as a percent, r, charged on an item can be determined using the formula StartFraction c Over p EndFraction minus 1 equals r. – 1 = r, where c is the final cost of the item and p is the price of the item before tax. Louise rewrites the equation to solve for the final cost of the item: c = p(1 + ). What is the final cost of a $40 item after an 8% tax is applied? $
