Please help with 45. I know the answer i just on't know how to explain it. Please and Thank you!!!

Answer:

1 hour

Step-by-step explanation:

First of all you multiply 20 by 5 to calculate the distance he travelled, which is 100 then you add 5 to 20 to get the new speed which is 25 finally you divide his distance by the new speed 100/25 which is 4 and as 5-4=1 he would have saved 1 hour.

Would be amazing if you marked brainliest :)

Answer:

Step-by-step explanation:

To find the number of bananas, we need to determine the proportion of bananas in the total number of fruits based on the given ratio.

Let's assume that the ratio of oranges, apples, and bananas can be represented by 8x, 5x, and 2x, respectively, where x is a common multiplier.

The sum of the parts in the ratio is 8x + 5x + 2x = 15x.

We know that the total number of fruits is 120. Therefore, we can set up the following equation:

15x = 120

To solve for x, we divide both sides of the equation by 15:

x = 120 / 15

x = 8

Now that we know the value of x, we can find the number of bananas by multiplying it by the corresponding part of the ratio:

Number of bananas = 2x = 2 * 8 = 16

So, there are 16 bananas in total.

We can add all the parts to the ratio and get 15. Out of 15 parts, 2 are bananas. Now we can calculate how many fruits are in one part. One fifteenth of 120 is 8, so there are 8 fruits in one part. 2 parts are bananas, so multiplying 8 with 2 gives us our answer, 16.

Answer:

Step-by-step explanation:

Let’s mark the Triangle Points as Point A, Point B, Point C.

Point A = 1x°

Point B = 2x°

Point C = 3x°

We know that the Angle Sum of a Triangle is equal to 180°.

So, Point A + Point B +Point C = 180°

   = 1x° + 2x° + 3x° = 180°

   = (1 + 2 + 3)x° = 180°

   = 6x° = 180°

   = x° = (180/6)°

   = x° = 30°

|   Point A = 1 * 30° = 30°    |         ⇒

Answer:

The monthly cost (in dollars) of a long-distance phone plan is a linear function, which means that the cost is proportional to the total calling time (in minutes). To calculate the monthly cost for 66 minutes of calls, we can use the following equation:

Cost = m * Minutes + b

Where m is the slope of the line, and b is the y-intercept. To find m and b, we can use the two given points: (51, $17.32) and (79, $20.96).

Using the slope formula: m = (20.96 - 17.32)/(79 - 51) = 0.44

We can then use the y-intercept formula: b = 17.32 - 0.44*51 = -4.64

Now we can plug in 66 for Minutes and solve for Cost: Cost = 0.44*66 - 4.64 = $17.12

Therefore, the monthly cost for 66 minutes of calls is $17.12.

Answer:

\(60\) times

Step-by-step explanation:

There are \(6+4+3+2=15\) marbles in total. Out of those, \(3\) are blue, so the probability of pulling a blue marble is \(\frac{3}{15}=\frac{1}{5}\). However, this is only the probability of pulling a blue marble when \(1\) marble is pulled at random. Therefore, we can expect a blue marble to be pulled \(\frac{1}{5}*300=60\) times if \(1\) marble is pulled \(300\) times at random. Hope this helps!

Answer:

7. Answer is 1236.25$

8. Answer is 143.75$

9. Answer is 16.485$

10. Answer is 6.825$

11. Answer is 31.25%

12. Answer is 0.125 for the decimal section and 12.5% for the percent section.

Step-by-step explanation:

7. 7.5 percent of 1150 is 86.25 and 86.25 + 1150 is 1236.25.

8. 15 percent of 125 is 18.75 therefore 125 + 18.75 is equal to 143.75.

9. 3.50 + 2.25 + 9.95 + 15.7 and 5 percent of 15.7 is 0.785 and 15.7 + 0.785 is 16.485.

10. 4.25 plus 2.25 is 6.50 and 5% of 6.50 is 0.325 and 6.50 plus 3.25 is 6.825.

11. 63 plus 25 is 88 so 88 is 68.75 percent of 128 and 100 minus 68.75 is 31.25 so 31.25 is the answer.

12. 1/8 is 12.5 percent so for the percent section it is 12.5 and for the decimal section 0.125

Answer:

-4/35

Step-by-step explanation:

Considering area (A) of garden as 30 square feet:

30 = x(2x+7)

Now we need to expand it:

x(2x+7) = 2x^2 + 7x

2x^2 + 7x = 30

Adding this into an Algebra calculator gives us 5/2 or 2.5

So x = 2.5

To prove this:

2(2.5) + 7 = 12

14 * 2.5 = 30

Add up those values

10+24+25+26+30+30+32+33+40+45+46 = 341

Then divide over n = 11 which is the sample size.

341/11 = 31 is the arithmetic mean.
