Answer:

v = - [tex]\frac{39}{20}[/tex]

Step-by-step explanation:

Given

- [tex]\frac{1}{2}[/tex] - [tex]\frac{2}{3}[/tex] v = [tex]\frac{4}{5}[/tex]

Multiply through by 30 ( the LCM of 2, 3 and 5 )

- 15 - 20v = 24 ( add 15 to both sides )

- 20v = 39 ( divide both sides by - 20 )

v = - [tex]\frac{39}{20}[/tex]

Answer:

[tex]v=-\frac{39}{20}[/tex]

Step-by-step explanation:

Given the expression

[tex]-\frac{1}{2}-\frac{2}{3}v=\frac{4}{5}[/tex]

Add 1/2 to both sides

[tex]-\frac{1}{2}-\frac{2}{3}v+\frac{1}{2}=\frac{4}{5}+\frac{1}{2}[/tex]

[tex]-\frac{2}{3}v=\frac{13}{10}[/tex]

Multiply both sides by 3

[tex]3\left(-\frac{2}{3}v\right)=\frac{13\cdot \:3}{10}[/tex]

[tex]-2v=\frac{39}{10}[/tex]

Divide both sides by -2

[tex]\frac{-2v}{-2}=\frac{\frac{39}{10}}{-2}[/tex]

[tex]v=-\frac{39}{20}[/tex]

Therefore,

[tex]v=-\frac{39}{20}[/tex]

Answer:

True

Step-by-step explanation:

Bcuz, some thing's power 0is 1

According to the zero power rule of exponents, 3^0 = 1. The statement 3^0 ≠ 1 is FALSE.

The zero power rule is a property of exponents which simply states that whatever base that is raised to the power of zero would always be equal to one, i.e., x^0 = 1.

We are given that 3^0 ≠ 1. Based on the zero power rule of exponents, this is FALSE because 3^0 = 1.

Answer:

a=15

Step-by-step explanation:

Pythagorean Theorum says that a²+b²=c², so if we square b and c, subtract b² from c², and then square root that answer, it will equal a.

a²+8²=17²

8²=64

17²=225

225-64=225

√225=15

Answer:

C: 13cm

Step-by-step explanation:

Given;

length of the rectangle, L = (x + 4) cm

width of the rectangle, W = [tex]\frac{2}{4}x[/tex] cm

perimeter of the rectangle, P = 35 cm

The perimeter of a rectangle is given as;

P = 2(L + W)

Substitute the givens;

[tex]35 = 2[(x+ 4) + \frac{2x}{4} ]\\\\35 = 2[\frac{6x}{4} +4]\\\\35 = 3x+8\\\\3x = 27\\\\x = \frac{27}{3}\\\\x = 9[/tex]

Then, L = (x + 4) cm

L = (9 + 4) cm

L = 13 cm

Therefore, the length of the rectangle is 13 cm

Answer: 5(x-1)

Step-by-step explanation:

5*x = 5x

5*-1 = -5

therefore the answer is 5(x-1)

5x-5 distributed is 5(x-1).

The common factor of 5x and 5 is 5.

5x divided by 5 is 1x or x.

5 divided by 5 is 1.

So the answer is 5(x-1).

Answer:

  A)  5x+12 = -12x-12

  D)  5x+12 = -5x-12

Step-by-step explanation:

If you subtract the right side expression from both sides, you will get an equation with something equal to zero. If the 'something' has a variable in it, there is exactly one solution.

A: (5x+12) -(-12x-12) = 17x+24 = 0 . . . one solution

B: (5x+12) -(5x-5) = 17 = 0 . . . . no solutions

C: (5x+12)-(5x+12) = 0 = 0 . . . . infinite solutions

D: (5x+12) -(-5x-12) = 10x +24 = 0 . . . one solution

Answer:

It is the second triangle.

Step-by-step explanation:

This is because the area of the square is given as 25^2 as the perpendicular, 144^2 as the base, and the hypotenuse is 169^2.

Length of the perpendicular = 5^2 (Because 25^2 / 5^2)

Length of the base = 12^2

Length of the hypotenuse = 13^2

So, the Pythagoras theorem is,

=> [tex]H^{2} = P^{2} + B^{2}[/tex]

=> [tex]13^{2} =12^{2} +5^{2}[/tex]

This is true, because, 13*13 = 12*12 + 5*5

=> 169 = 144 + 25

=> 169 = 169

2nd option: 0.07

Step-by-step explanation:

100% in decimal form is 1.00. S0, 7 is really 0.07. Hope this helps. Mark brainliest if it does!

The expression which represents the amount of tax on a t-shirt that cost x dollars, if tax is 7% is 0.07x.

The percentage is defined as a given amount in every hundred. It is a fraction with 100 as the denominator percentage is represented by the one symbol %.

The percentage is just like the amount of that value but between 1 to 100 and it is very useful to predict for example if you say 678 then we have to know about the full number also but if you say 80% then it becomes clear.

Given that,

Cost of t-shirt = x dollars

Tax is 7% which means tax is 7% of the cost of the t-shirt

7% of x ⇒ 7/100 × x = 0.007x

Hence "The expression which represents the amount of tax on a t-shirt that cost x dollars, if tax is 7% is 0.07x".

Answer:

[tex]\dfrac{3}{11}[/tex]

Step-by-step explanation:

Given that:

A drawer contains 6 pink and 5 yellow gloves.

Two gloves are randomly drawn without replacement.

To find:

The probability that the two gloves drawn are both pink.

Solution:

First of all, let us have a look at the formula for Probability of an event E:

Formula for probability of an event E can be observed as:

[tex]P(E) = \dfrac{\text{Number of favorable cases}}{\text {Total number of cases}}[/tex]

Here, number of favorable cases are to draw 2 pink gloves out of 6, which is equal to:

[tex]_6C_2 = \dfrac{6\times 5}{2} = 15[/tex]

Here, Total number of cases are to draw 2 gloves out of 11, which is equal to:

[tex]_{11}C_2 = \dfrac{11\times 10}{2} = 55[/tex]

Now, the required probability is:

[tex]P(2\ pink\ gloves) = \dfrac{15}{55}\\\Rightarrow P(2\ pink\ gloves) = \dfrac{3}{11}[/tex]

Therefore, the answer is:

[tex]\dfrac{3}{11}[/tex]
