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

Answer:

60-11x < 20

Step-by-step explanation:

Let's first set out all the information we know.

So, the first thing that will be in the inequality would be $60. Since you are wasting money, you have to subtract.

The thing that will be subtracted more than once is $11, so it will have the variable "x" added to it.

What we have so far is:

60-11x

Because this is an inequality, we will have a less than sign.

After that, we can conclude that $20 will come next because that is at the end of the problem.

So, the answer is:

60-11x < 20

Answer:

48

Step-by-step explanation:

you first have to take the 3 and 5 and multiply them by 6 individually which will give you 18 and 30 respectively, which so happens to be 12 less than the other, then you add them together and you have your answer

Answer:

The lengths 7, 40 and 41 cannot be sides of a right triangle. The lengths 12, 16, and 20 can be sides of a right triangle.

Step-by-step explanation:

You can test this by using the Pythagorean theorem, which states a^2+b^2=c^2

with 7,40 and 41

7^2+40^2 does not equal to 41^2

but with 12,16, and 20

12^2+16^2=20^2

therefore, the last statement is correct.

The triangles are the same

CA= 8.5

AT=5

DG=12

T=70

O=57

C=53

Step-by-step explanation:

This can be a little brain bending but try to imagine rotating ∆DOG to the left once. The bottom side is now OGD. Now, the triangles will look similar. Here is the rule:

The SAS rule states that: If two sides and the included angle of one triangle are equal to two sides and included angle of another triangle, then the triangles are congruent. An included angle is an angle formed by two given sides.

so, side CA is equal to side DO. Side CT is equal to side DG, and side AT is equal to side OG. The answers to the first column are:

CA=8.5m

AT=5m

DG=12m

Now, because the sides are equal, the angles are equal:

>T is the same as >G. =70°

>A is the same as>O = 57°

The angles of a triangle have to add up to 180°, so

70° + 57° = 127°

180°- 127° = 53°

So, angles D and C equal 53°.

Answer:

1.88261%

Step-by-step explanation:

Use the formula (E - T) / |T| * 100

(92 - 90.3) / |90.3| * 100

1.7 / 90.3 * 100

0.0188261 * 100

And you get a 1.88261 percent error :)

Answer:

Answer:

First number = 60 and another number = 48

Step-by-step explanation:

Let two numbers are 5x and 4x.

The two number are differ by 12. We need to find the numbers.

ATQ,

5x-4x = 12

x = 12

Now first number = 5x

= 5(12)

= 60

Other number = 4x

= 4(12)

= 48

Hence, the numbers are 60 and 48.

Answer:

180° in a triangle

180 = (2x + 3) + (4x + 2) + (2x - 1)

180 = 8x + 4

180 - 4 = 176

176 = 8x

176/8 = x

X = 22

proof:

A = 2 X 22 + 3 = 47

B = 4 X 22 + 2 = 90

C = 2 X 22 - 1 = 43

47 + 90 + 43 = 180°

Answer: 2 and 1/4 cups of oats (9/4 cups of oats)

Step-by-step explanation:

We know that, for the recipe, we need 3/4 cups of oats.

Now, you want to triple the recipe (then you need to use 3 times more ingredients).

This means that, if for the recipe you needed 3/4 cups of oats, when we triple that we have:

3*(3/4 cups) = 9/4 cups

This means that you need to use 9/4 cups of oats.

And we could also write this as:

9/4 cups = 8/4 cups + 1/4 cups = 2 + 1/4 cups of oats.

Answer:

Step-by-step explanation:

add 3u to both sides

7u=35

divide both sides by 7

u=5

Answer:

x= -10

Step-by-step explanation:

So because the angle 55 is part of the same line as one of the unknown angles you can do 180-55 to find that first angle at the top, which is 125.

Next add all three angles (125 + x + 35 + x + 40)=180

Combine the x values to get 2x and subtract the three values from 180

Then 2x= -20, x should be equal to -10

You can plug x back into the values and check your work by adding all the values again, making it all equal to 180 degrees again

Answer:

third option

Step-by-step explanation:

let g(x)=y

(x-1)³/2-3=y

(x-1)³/2-3/1=y

(x-1)³-6/2=y

(x-1)³-6=2y

(x-1)³=2y+6(find cubic root of both sides)

(x-1)=³√(2y+6)

x=³√(2y+6)+1

Replace y with g for the inverse

g^-1(x)=³√(2x+6)+1

Answer:

C

Step-by-step explanation:

The negatives are always the coldest

Answer:

The answer would be C, or -10, -5, 0, 8

Step-by-step explanation:

This is because the least greatest number is -10, which is a negative number, and increases to the positive numbers, which ends with 8.

A, D, and D are incorrect because the numbers aren't listed in order from least to greatest. The bigger the negative number, the least it would be in the list, while the bigger the positive number, the greater it would be in the list.

[tex]8x^{2}y^{4}[/tex]         Answer B and C

Step-by-step explanation:

When a variable gets squared it looks like this (the exponent gets cut in half):

[tex]\sqrt{x^{2} }[/tex]=[tex]x[/tex]

So The square root of 64 is 8:

8

Then the next two exponents cut in half:

[tex]x^{2} y^{4}[/tex]

Then we put it back together:

[tex]8x^{2}y^{4}[/tex]

Letter B is the correct choice along with C because of distributive Property.

Answer:

$14

Step-by-step explanation:

Multiply each mile run by the amount of money for each mile. In this case, you run 4 miles and get $2 for each mile, so that's $8 for you. Your friend runs 3 miles, so that's another $6. Adding $8 plus $6 = $14.

You and your friend raised together 14 dollars for the charity by running.

A numerical expression is a mathematical statement written in the form of numbers and unknown variables. We can form numerical expressions from statements.

Given, You and your friend participate in a charity run. For every mile run, $2 is donated to the charity.

Also given that You run 4 miles and your friend runs 3 miles.

Therefore, The amount in dollars you and your friend raised for the charity

is (2×4) + (2×3) dollars.

= 8 + 6 dollars.

= 14 dollars.

So, Both of them together raised 14 dollars for the charity.
