13/15 × 1 1/39 multiplying/dividing fractions help me ​

Answers

Answer 1

Before multiplying two fractions together, always try to cross-cancel.

So in this problem, the 13 and 39 cross-cancel to 1 and 3.

So we have 1/15 × 11/3 which is 11/45.

Remember, multiply across the numerators and denominators.

Answers

Answer: If they start running at the same time, then it will take 30 minutes until they complete a lap together.

Step-by-step explanation:

Given:  Stephanie can run one lap around a track in 5 minutes. Lisa can run one  lap in 6 minutes.

If they start running at the same time, then the time they will take to complete a lap together = LCM (5,6)

prime factorization: 5=5   , 6 =2 x 3

So, LCM(5,6) = 5 x 2  x 3 = 30

Hence, it will take 30 minutes until they complete a lap together.

Answer:

1/5 = 2/10 = 3/15 = 4/20

= 5/25 = 6/30 = 7/35 = 8/40

= 9/45 = 10/50 = 11/55 = 12/60

= 13/65 = 14/70 = 15/75 = 16/80

= 17/85 = 18/90 = 19/95 = 20/100

= 21/105 = 22/110 = 23/115 = 24/120

= 25/125 = 26/130 = 27/135 = 28/140

= 29/145 = 30/150 = 31/155 = 32/160

= 33/165 = 34/170 = 35/175 = 36/180

= 37/185 = 38/190 = 39/195 = 40/200

= 41/205 = 42/210 = 43/215 = 44/220

= 45/225 = 46/230 = 47/235 = 48/240

= 49/245 = 50/250 = 51/255 = 52/260

= 53/265 = 54/270 = 55/275 = 56/280

= 57/285 = 58/290 = 59/295 = 60/300

= 61/305 = 62/310 = 63/315 = 64/320

= 65/325 = 66/330 = 67/335 = 68/340

= 69/345 = 70/350 = 71/355 = 72/360

= 73/365 = 74/370 = 75/375 = 76/380

= 77/385 = 78/390 = 79/395 = 80/400

= 81/405 = 82/410 = 83/415 = 84/420

= 85/425 = 86/430 = 87/435 = 88/440

= 89/445 = 90/450 = 91/455 = 92/460

= 93/465 = 94/470 = 95/475 = 96/480

You have budgeted $3,200 per month for your total expenses. The cost of rent per month is $1,300 and the cost of food is $350. To stay within your budget, all other costs C must be no more than what amount (in $)?

Answers

Answer:

All other costs must be $1,550 or less

Step-by-step explanation:

1300+350=1650

3200-1650=1550

Using some mathematical operations, we know that to stay within the budget, the other cost will not be more than $1,550.

What exactly are mathematical operations?An operation is a mathematical function that transforms zero or more discrete input values into discrete output values. The complexity of the operation depends on how many operands there are. The rules that specify the order in which specific operations should be carried out in order to solve an expression are referred to as the order of operations. Parentheses, exponents, multiplication, division (from left to right), addition, and subtraction are the order of operations. (Left to Right) PEMDAS (from left to right).

So, cost C must be no more than:

The budget is $3200.The cost of rent and food is $1300 and $350.

Then, the remaining money will be:

3200 - (1300 + 350)3200 - 1,650$1,550

Therefore, using some mathematical operations, we know that to stay within the budget, the other cost will not be more than $1,550.

What is the actual distance between the school and the park?

solution:

        12 cm     =   4 cm                  

          X km            5 km

cross multiply:

On a number line, suppose the coordinate of Ais 0, and AR = 15. What are the possible coordinates of the midpoint of AR?

Answers

Given :

On a number line, suppose the coordinate of A is 0, and AR = 15.

To Find :

the possible coordinates of the midpoint of AR.

Solution :

Their can be two points R which is at a distance of 15 units from the A .

One is -15 and other is 15.

Now, mid-point of A(0) and R(-15) is M (-7/2).

Also, mid-point of A(0) and R(15) is M (7/2).

Therefore, possible coordinates of the midpoint of AR is 7/2 , -7/2.

Hence, this is the required solution.

Before each class, I either drink a cup of coffee, a cup of tea, or a cup of water. The probability of coffee is 0.7, the probability of tea is 0.2, and the probability of water is 0.1. If I drink coffee, the probability that the lecture ends early is 0.3. If I drink tea, the probability that the lecture ends early is 0.2. If I drink water, the lecture never ends early. 1) What’s the probability that I drink tea and finish the lecture early? 2) What’s the probability that I finish the lecture early? 3) Given the lecture finishes early, what’s the probability I drank coffee?

Answers

Answer:

1. Probability of drinking tea and finishing the lecture early = 0.2 * 0.2 = 0.04 or 4%

2. Probability of finishing the lecture early = 50% (0.3 + 0.2).

3. Probability of drinking coffee = 0.21 or 21% (0.7 * 0.3)

Step-by-step explanation:

a) Data and Calculations:

            Probability   Early Ending    Expected Probability

Coffee     0.7               0.3                     0.21

Tea          0.2               0.2                    0.04

Water      0.1                

b) The probability of drinking coffee, tea, or water is the chance that the lecturer drinks either coffee or tea or water.  The combined probability of the three actions is always 1.  The expected probability is the weighing of the probabilities with another event, ending the lecture early.  This is obtained by multiplying their respective probabilities.

Use the quadratic formula, x=−b±b2−4ac√2a, to solve the equation −2x2−6x+3=0. Match each step to the correct method for solving the equation.

Answers

Answer:

[tex]\displaystyle x=\frac{-3+ \sqrt{15}}{2}\approx0.4365\text{ or}\\x=\frac{-3-\sqrt{15}}{2}\approx-3.4365[/tex]

Step-by-step explanation:

We are given the equation:

[tex]-2x^2-6x+3=0[/tex]

And we want to solve it using the quadratic formula:

[tex]\displaystyle x=\frac{-b\pm \sqrt{b^2-4ac}}{2a}[/tex]

First, let's identify our coefficients.

The a is the coefficient in front of the x² term, so a = -2.

b is the coefficient in from of the x term, so b = -6.

And c is the constant so c = 3.

Substitute:

[tex]\displaystyle x=\frac{-(-6)\pm \sqrt{(-6)^2-4(-2)(3)}}{2(-2)}[/tex]

Simplify. -(-6) is just 6. (-6) squared is 36. -4(-2)(3) is 24. And 2(-2) is -4. So:

[tex]\displaystyle x=\frac{6\pm \sqrt{36+24}}{-4}[/tex]

Add:

[tex]\displaystyle x=\frac{6\pm \sqrt{60}}{-4}[/tex]

Simplify the square root:

[tex]\sqrt{60}=\sqrt{4\cdot 15}=\sqrt{4}\cdot\sqrt{15}=2\sqrt{15}[/tex]

So:

[tex]\displaystyle x=\frac{6\pm 2\sqrt{15}}{-4}[/tex]

Simplify by dividing everything by 2:

[tex]\displaystyle x=\frac{3\pm \sqrt{15}}{-2}[/tex]

Move the negative in the denominator to the numerator. The plus/minus sign will not change.

[tex]\displaystyle x=\frac{-3\pm \sqrt{15}}{2}[/tex]

So, our zeros are:

[tex]\displaystyle x=\frac{-3+ \sqrt{15}}{2}\approx0.4365\text{ or}\\x=\frac{-3-\sqrt{15}}{2}\approx-3.4365[/tex]

If a2 = 5 and a8 = 35, what is the value of a30?

Answers

Answer:

a(30) = 145

Step-by-step explanation:

a(n) = a(1) + (n-1)d

d = 5

a(30) = 0 + (30-1)5

a(30) = 0 + (29)5

a(30) = 0 + 145

a(30) = 145

Using the concept of arithmetic sequence, the value of a30, which is the 30th term of the sequence is 145

The common difference, d = 35 / 7 = 5

The nth term of an arithmetic sequence is obtained using the relation :

A(n) = a1 + (n - 1)d

a1 = first term

a1 = a2 - d = 5 - 5 = 0

Hence,

A(30) = 0 + (30 - 1)5

A(30) = 0 + 29(5)

A(30) = 145

Therefore, the value of the 30th term of the sequence is 145.
