Answer:

1.166666 ; 1.4 ; James

Step-by-step explanation:

Given that:

Path from bottom to top = distance = 2 miles

Time taken = distance /speed

James :

To climb up:

Time = 2 / 3 = 2/3 hours

Coming down :

Time = 2 / 4 = 1/2 hours

Total time taken = 2/3 + 1/2 = 1.166666 hours

1.166666 * 60 = 70 minutes

Lucas :

To climb up:

Time = 2 / 2 = 1 hour

Coming down :

Time = 2 / 5 = 2/5 hours

Total time taken = 2/3 + 1/2 = 1.4 hours

1.4 * 60 = 84 minutes

James was faster :

1.166666 < 1.4

hope it will help you..........

Answer: X=2.5,  Y= 6.5

Step-by-step explanation:

It seems the triangle on the left is being transformed and a scale factor of 0.5 or 1/2 is being used since the 6 is half of 12. Therefore you divide 5 by 2 to get 2 and the 13 by 2 to get 6.5.

Answer: $191.67

Step-by-step explanation:

When paying back mortgages, the monthly payment has two components: an interest payment component and a principal repayment component.

The interest payment component is based on the total amount of debt still to be paid at the time and the principal repayment component is the rest of the payment after the interest has been deducted.

This interest is in a yearly rate so should be combined to a monthly rate as the payments are monthly:

= 5% / 12

= 5/12%

Interest = Mortgage remaining * interest rate

= 46,000 *  5/12%

= $191.67

Step-by-step explanation:

Temperature at 3pm: 4° F

After the decrease in temperature per hour by 2°F

Temperature at 4pm: 2°F

Temperature at 5pm: 0°F

Temperature at 6pm: -2°F

Temperature at 7pm:-4°F

Hence we can say that the temperature at 7pm is -4°F

Answer:

9.4247

Step-by-step explanation:

c= πd, c=(3.14)d , 3 is the diameter so we put it in the d spot. So c=(3.14)3 and you multiply those together to get the circumference.

Answer:

1.) 2(8x-1)+2(2x+4)

2.) 16x-2+4x+8

3.) (20x+6)

Step-by-step explanation:

The perimeter of the rectangle is (20x + 6)inches

The formula for calculating the perimeter of a rectangle is expressed as:

P = 2l + 2w

Given that;

l = 8x - 1

w = 2x + 4

Susbtitute

P = 2(8x - 1) + 2(2x + 4)

Expand

P = 2(8x) - 2(1) + 2(2x) + 2(4)

P = 16x - 2 + 4x + 8

P = 16x + 4x - 2 + 8

P = 20x + 6

Hence the perimeter of the rectangle is (20x + 6)inches

Answer:

1.6875

Step-by-step explanation:

Step-by-step explanation:

Notice that:

15x = 5 * 3x and 10y = 5 * 2y.

Since there is a common factor of 5,

we can take out the factor.

=> 15x + 10y = (5)(3x) + (5)(2y) = 5(3x + 2y).

Answer:

The answer is 4/3 or 1.33 square units.

Step-by-step explanation:

Length = 1 + 7/9 = 16/9 units.

Width = 3/4 units.

Since area of rectangle = Length * Width

Area = 16/9 * 3/4 = 4/3 square units.

Answer:

Please check explanations

Step-by-step explanation:

Here, we want to interpret the meaning of the slope

The slope generally refers to the change in y values with corresponding change in x value

with respect to this question, we can see that the slope is negative

What this mean is that the rate of change in the level of oxygen measured in liters is decreasing with an increase in the time

This means that as more time elapses, more oxygen is used up leading to a decrease in the liters of oxygen present

Answer:

No

Step-by-step explanation:

we can start by dividing finding how many times 60 goes into 156.

It goes in 2 times with 120 miles.

we can subtract 120 from 156

this leaves us with 36 miles.

36 > (60 * .5)

between 7:30 and 10:00 there are 2.5 hours.

the car ride would take 2.6 hours meaning Kim wouldn't arrive before 10 am.

Answer:

Yes Noah's method will always work

Step-by-step explanation:

Noah's method states that:

To find 20% of a number he divides the number by 5. For example, 20% of 60 is 12.

Noah's method will always work because:

20% = 20/100

Simplifying 20/100 to the least fraction = 20/100 = 1/5

20% of x = 1/5 × x

= x/5 = x ÷ 5

Applying this to the examples

20% of 60 = 1/5 × 60

= 60/5 = 12.

Therefore, Noah's method will always work.

Answer:

Simplifying  the expression: [tex]2(\frac{3}{5}x+\frac{2}{3}y-\frac{1}{4}x-1\frac{1}{2}y +3)[/tex] we get [tex]\mathbf{42x-100y-360}[/tex]

Step-by-step explanation:

We need to simplify the expression: [tex]2(\frac{3}{5}x+\frac{2}{3}y-\frac{1}{4}x-1\frac{1}{2}y +3)[/tex]

First we will solve terms inside the bracket

[tex]2(\frac{3}{5}x+\frac{2}{3}y-\frac{1}{4}x-1\frac{1}{2}y +3)[/tex]

Converting mixed fraction [tex]1\frac{1}{2} y[/tex] into improper fraction, we get: [tex]\frac{3}{2}y[/tex]

Replacing the term:

[tex]2(\frac{3}{5}x+\frac{2}{3}y-\frac{1}{4}x-\frac{3}{2}y +3)[/tex]

Now, taking LCM of: 5,3,4,2 we get 60

Now multiply 60 with each term inside the bracket

[tex]2(\frac{3}{5}x\times60+\frac{2}{3}y\times60-\frac{1}{4}x\times60-\frac{3}{2}y\times60 +3\times60)\\2(3x\times12+2y\times20-1x\times15-3x\times30-3\times60)\\2(36x+40y-15x-90y-180)[/tex]

Now, combine like terms

[tex]2(36x-15x-90y+40y-180)\\2(21x-50y-180)[/tex]

Now, multiply all terms with 2

[tex]42x-100y-360[/tex]

So, Simplifying  the expression: [tex]2(\frac{3}{5}x+\frac{2}{3}y-\frac{1}{4}x-1\frac{1}{2}y +3)[/tex] we get [tex]\mathbf{42x-100y-360}[/tex]
