At union station, you notice that three subway lines just arrived at the same time. How long must you wait until all three lines

Dmitry_Shevchenko [17]

Answer:

You must wait 60 minutes for all three lines to arrive at Union Station at the same time again.

Step-by-step explanation:

The complete question in the attached figure

Step 1

Find the least common multiple (LCM) of the three numbers

List the prime factors of each number

$10=(2)(5)\\12=(2^2)(3)\\15=(3)(5)$

Multiply each factor the greatest number of times it occurs in any of the numbers to find out the LCM

The LCM is equal to

$(2^2)(3)(5)=60$

therefore

You must wait 60 minutes for all three lines to arrive at Union Station at the same time again.

Explain why 1/2 ab sin(theta) gives the area of a triangle with sides a and ???? and included angle theta.

Jet001 [13]

Answer:

Please find the attachment.

Step-by-step explanation:

We are asked to explain why $\frac{1}{2}ab\cdot \text{sin}(\theta)$ gives the area of a triangle with sides a and b and included angle theta.

We know that area of a triangle is equal to half the product of base and height of the triangle.

$\text{Area of triangle}=\frac{1}{2}\cdot bh$

Upon looking at our given triangle, we can see that the base of the triangle is equal to 'a'.

The height of the triangle can be determined using sin(theta) as sine relates opposite side of right triangle with its hypotenuse.

$\text{sin}=\frac{\text{Opposite}}{\text{Hypotenuse}}$

$\text{sin}(\theta)=\frac{h}{b}$

$h=b\cdot \text{sin}(\theta)$

Upon substituting our given values in area formula, we will get:

$\text{Area of triangle}=ab\cdot \text{sin}(\theta)$

Hence, proved.

IS IT (A , B ) CAN SOMEONE HELP PLEASE !!!!!!!!!!!!!!!!!

Answer: 1% is your answer

It's (1/100) * 100 or 1% is the percentage strength of a 1:100 solution.

Step-by-step explanation:

l NOTE:

l To change ratio strength to percent strength, it is

sometimes convenient to "convert" the last two zeros in

a ratio strength to a percent sign (%),

l change the remaining ratio to a common fraction, and

then to a decimal fraction in expressing percent.

l Examples:

l 1:100 =1/1% = 1%

l 1:200 = ½% = 0.5%

l 3:500 = 3/5% = 0.6%

l 1:2500 = l/25% = 0.04%

l 1:10,000 = 1/100% = 0.01%
