Answer:

60/54 =10/9 or 1 1/9

Step-by-step explanation:

Answer:

Step-by-step explanation:

Use the reciprocal to find the answer, and then simplify. When dividing fractions, you multiply by the reciprocal.

5/6 * 12/9 = 60/54

The simplest form of 60/54 is 1 1/9

Answer:

3:2

Step-by-step explanation:

First, we put 45 females to 30 males into a ratio:

45:30

Now we find the GCF of both 45 and 30 which is 15.

Since it's asking for the simplest form, we would divide 15 on both sides:

45/15 : 30/15

And we end up with our final answer as 3:2

Answer:

It's the last one where x=3 and y=2

Explanation:

Replace x and y with 3 and 2. It then becomes

-4(3) + 8(2) = 4

Solve. -4 × 3 is -12 since a positive times a negative equals a negative. 8 × 2 is 16. Bring down the 4.

-12 + 16 = 4

When solving something like this and you don't know what to do or how to solve it, you can subtract the smaller number from the larger number and then whether the sum is a negative or positive depends on the largest number. So here, 16 is the largest, so the sum will be positive. And 16-12 is 4, so the final answer is positive 4. You can also look at a number line and start from -12 and then add 16 and see which number you end at after adding 16.

Answer:

16 years

Step-by-step explanation:

Principal amount (P) = $600

Rate of interest (R) = 2.75%

Simple interest (S.I.) = $264

Let t denotes time period.

[tex]S.I.=\frac{PRT}{100}[/tex]

[tex]264=\frac{600(2.75)t}{100} \\\\t=\frac{264(100)}{600(2.75)}[/tex]

[tex]t=16[/tex] years.  

Therefore,

interest of $264 will be earned in 16 years.

Step-by-step explanation:

100ft=33 yards

20ft=6 yards

60ft=20 yards

33+6+20=59

Answer:

60 yards

Step-by-step explanation:

100 + 20 + 60= 180 ft

180 feet contributed into yards is 60.

Answer:

let number be x

30=5% of X

3000=5x

Answer:

1. Equation: y = -1.17491x + 81.791 (you may need to round!)

2. Correlation coefficient: -0.8566

3. Strong negative correlation because the correlation coefficient is close to -1

4. Sketch the scatterplot using north latitude as the x value and Jan mean temp as the y value on the graph

Step-by-step explanation:

Step 1: Go to desmos graphing calculator

Step 2: Insert a table

Step 3: Insert values into the table (shown in image) using the north latitude as the x value and jan mean temp as y value

Step 4: Go to line 2, and type "[tex]y_1 = mx_1 + b[/tex]" except replace "=" with ~ as shown in the image. Put the 1s as subscripts

Step 5: Scroll out. Desmos would've graphed the line of best fit and plotted the points. Under statistics, you can see that r is the correlation coefficient

Step 6: The correlation coefficient r will be between -1 and 1. If it is closer to -1 or 1, it is a strong correlation. If it is closer to 0, it is a weak correlation. For example. -0.6 is closer to -1 than it is to 0, so it is a strong negative correlation. You can see that r here is -0.8566, which is strong negative.

Step 7: Lastly, you need to make the equation. It will be in the form y = mx + b. If you look under "parameters", there will be a value for m and b. Plug that in to the equation. Check to see if you need to round.

Step 8: To graph the scatterplots, you can use the graph and the points that desmos plotted as a reference. Good luck!

I hope I did it right, we just finished this at school and I got 100% on the test. Comment with any questions. Best of luck! - brainpop72

Answer:

84

Step-by-step explanation:

8x6=48

2x4=8

4x7=28

48+28+8=84

Step-by-step explanation:

The numbers are given as;

100, 101, 102, 103, 104, 105, 106, 107, 108, 109, 110, 111, 112, 113, 114, 115, 116, 117, 118, 119, 120, 121, 122, 123, 124, 125

What is the probability of getting;

a) A number 108?

Probability = Number of favorable outcomes / Total number of outcomes

Number of favourable outcome = 1

Total number of outcomes = 26

Probability = 1 / 26

B) a number less than 107

Probability = Number of favorable outcomes / Total number of outcomes

Number of favourable outcome = 100, 101, 102, 103, 104, 105, 106 = 7

Total number of outcomes = 26

Probability = 7 / 26

c) A number greater than 120

Probability = Number of favorable outcomes / Total number of outcomes

Number of favourable outcome = 121, 122, 123, 124, 125 = 5

Total number of outcomes = 26

Probability = 5 / 26

Complete question :

Mr. Sawyer drove his car from his home to New York at the rate of 45 mph and returned over the same road at the rate of 40 mph. If his time returning exceeded his time going by 30 min, find his time going and his time returning.

Answer:

T1 = 4

T2 = 4.5

Step-by-step explanation:

Difference in time = 0.5 hour

Time = distance / speed

Let distance = d

Time, T1 = d / 45

Time, T2 = d / 40

d/40 - d /45 = 1/2

(45d - 40d) / 100 = 2

45d - 40d = 900

5d = 900

d = 180

T1 = 180 /45 = 4 hours

T2 = 180 / 40 = 4.5 hours

Answer:

b= 10 miles/hr and c= 5 miles/hr

Step-by-step explanation:

Let it's downstream and upstream speed be d and u respectively

also speed of the boat be b and speed of stream be c.

as per question d = 150/10= 15 miles/hr

and, u= 150/30= 5 miles/hr

also we know d= b+c = 15.....i and u = b-c= 5....ii

solving i and ii we get b= 10 miles/hr and c= 5 miles/hr

Plz Branliesst Answer\

Answer: A = 317

B = 61

Step-by-step explanation:

The following equation can be gotten from the question given. This will be:

A + B = 379 ........ i

A - B = 255 ........ ii

From equation i, make A the subject of the formula

A = 379 - B ...... iii

Put the value of A in iii into equation ii

A - B = 255

(379 - B) - B = 255

379 - B - B = 255

379 - 2B = 255

2B = 379-255

2B = 124

B = 124/2

B = 62 tons

Since A + B = 379

A + 62 = 379

A = 379 - 62

A = 317 tons
