Answer:

  72 feet

Step-by-step explanation:

Triangle JKM is similar to triangle PQM, so we have ...

  JK/KM = PQ/QM

  JK/(60 ft) = (6 ft)/(5 ft)

  JK = (60 ft)(6/5)

  JK = 72 ft

The height of the cliff is 72 feet.

Step-by-step explanation:

Isolate x.

[tex]\frac{x-2}{3}[/tex] + [tex]\frac{1}{6}[/tex] = [tex]\frac{5}{6}[/tex]

[tex]\frac{x-2}{3}[/tex] = [tex]\frac{5}{6}[/tex] - [tex]\frac{1}{6}[/tex]

[tex]\frac{x-2}{3}[/tex] = [tex]\frac{2}{3}[/tex]

[tex]\frac{x-2}{3}[/tex] × 3 = [tex]\frac{2}{3}[/tex] × 3

x - 2 = 2

Answer:

x=85

Step-by-step explanation:

let's angle c be x

39+56+x=180

95+x=180

x=180-95

x=85

Answer:

85 degrees

Step-by-step explanation:

In similar triangles, corresponding angles are congruent, or have the same measure.

Therefore, angle B must also be 56 degrees. In a triangle, there are 180 degrees.

A+b+c=180

39+56+c=180

c=85 degrees.

Answer: cups of cake mix: 19/24 cups of water: 11/64

Step-by-step explanation:

Because it is not dividing by a fraction all you have to do is multiply its denominator by 8.

The derivative of [tex]y = 3x^4 - 2x^3 - 7x + 5[/tex] with respect to x is

dy/dx = 12x³ - 6x² - 7.

We have,

The power rule states that if we have a term of form a[tex]x^n[/tex], the derivative with respect to x is given by [tex]d/dx(ax^n) = nax^{n-1}.[/tex]

Applying the power rule, we differentiate each term as follows:

[tex]d/dx(3x^4) = 3 \times 4x^{4-1} = 12x^3\\d/dx(-2x^3) = -2 \times 3x^{3-1} = -6x^2\\d/dx(-7x) = -7 \times 1x^{1-1} = -7[/tex]

d/dx (5) = 0 (since 5 is a constant)

Combining these derivatives, we get:

dy/dx = 12x³ - 6x² - 7

Therefore,

The derivative of [tex]y = 3x^4 - 2x^3 - 7x + 5[/tex] with respect to x is

dy/dx = 12x³ - 6x² - 7.

Answer:

2 block east from home

Step-by-step explanation:

Given an expression for how many blocks east Robert is from his home after finding his wallet as the sum 7+​(−​5),

Simplifying the given expression

7+(-5) = 7-5 (note that the product of a plus and minus sign will give a minus sign)

7-5 = 2

Hence Robert will be 2 block east from home

Answer:

The total is $38.1

Step-by-step explanation:

The tax is $2.1, The tip is $6.

Percentage is the part of the whole expressed in the fraction of hundred.

The total cost of the meal after the tip and tax is $38.1.

Percentage of a number or ratio expressed in the form of fraction of hundred.

Given information-

The total cost of meal before tax and tip is $30.

The total sales tax is 7%.

The tip added to the cost of meal is 20%.

As, the total sales tax is 7% and cost of the meal is $30. Thus the total sales tax amount is,

[tex]s_t=30\times\dfrac{7}{100} \\s_t=2.1[/tex]

Thus the amount of sales tax is 2.1.

As the the tip added to the cost of meal is 20% and the cost of the meal is 32.1 after the tax. Thus the amount of meal after the 20 % tip is,

[tex]s_t=30\times\dfrac{20}{100} \\s_t=6.00[/tex]

The amount of the tip of the meal after the tax is $6.00.

The cost of meal after the tip and tax is,

[tex]C=30+2.1+6\\C=38.1[/tex]

Hence the total cost of the meal after the tip and tax is $38.1.

Answer:

You first need to know what number 6 4/5 is, which is 6.8. To figure it out, you multiply 6 by 5 then add 4 and put the number you get on top of the fraction so it would be 34/5 = 6.8

6.9 is the answer

6.9 is bigger than 6.8 and smaller than 7

Answer:

m=10

w=15

Step-by-step explanation:

m + w = 25

3m + 4w = 90

Let's do substitution, first by solving the first equation for m.

m = 25 - w

Substitute!

3(25 - w) + 4w = 90

75 - 3w + 4w = 90

w = 15

m = 25 - 15 = 10

The percent of increase is 10% or 5. If you multiply 20 x 0.1, you get 2. Then, you add 20 and 2 together to result with $22. Therefore, the answer is 10% or a 10% increase.

Answer:

1. 5

2. [tex]\sqrt{85}[/tex]

3. [tex]\sqrt{26}[/tex]

Step-by-step explanation:

1. just count the units: 5 units

2. Find the slope = rise/run = -7/6

you now have a right triangle, one side is 7 units (from the rise), and the other is 6 units (from the run)

use the pythagorean theorem to find the hypotenuse.

[tex]a^{2} +b^{2} =c^{2}[/tex]

[tex]7^{2} + 6^{2} = c^{2}[/tex]

49 + 36 = [tex]c^{2}[/tex]

85 = [tex]c^{2}[/tex]

[tex]\sqrt{85} = \sqrt{ c^{2}[/tex]

[tex]\sqrt{85} = c[/tex]

Simplify the radical, but [tex]\sqrt{85}[/tex] is farthest that it can go, so that is the answer.

3. same process as 2

slope = -1/5

[tex]1^{2} + 5^{2} = c^{2}[/tex]

1 + 25 = [tex]c^{2}[/tex]

26 = [tex]c^{2}[/tex]

[tex]\sqrt{26} = c[/tex]

That is the farthest it can go, so that will be the answer.

Step-by-step explanation:

Okay, this is a standard division problem, so our equation is:

but then we have to covert the mixed number to an improper fraction:

12/5 ÷ 3/4

do the cross thingy:

4/5 x 4/1 = 16/5 = 3 1/5
