find tan a in a triangle
a 20/21
b 21/29
c 21/20
d 20/29

Answer:

We are known that Katya and her friends stand in a circle and both neighbors are of same gender this means that the person on the right and the person on the left of anyone in the circle will be of same gender either a girl or a boy.

We are given that there are five boys, we could have considered the circle to be only composed of boys but we are given there is a girl Katya within it and it is also mentioned that 'Katya and her friends' that means there can be more girls in the circle.

Now when we draw a circle on a page and mark points K for Katya and boys B1 and B2 on right and on the left of Katya we will get to know that after each boy there has to be a space vacant because on that space a girl should be positioned only then we will meet the criteria of both gender's same on the neighbor side of each person.

Also we will mark boys B1,B2,B3,B4,B5 as five boys and leave space vacant for girls and with those vacant spaces we get to know there will be 4 vacant spaces and one is Katya herself.

Therefore there will be a total of five girls in the circle one is Katya and other four.

Answer:

x = 144

Step-by-step explanation:

[tex] x^\frac{1}{2} - 4 = 8 [/tex]

Add 4 to both sides.

[tex] x^\frac{1}{2} = 12 [/tex]

Square both sides since x^(1/2) is the same as sqrt(x).

[tex] (x^\frac{1}{2})^2 = (12)^2 [/tex]

[tex] x^{\frac{1}{2} \times 2} = 144 [/tex]

[tex] x^1 = 144 [/tex]

[tex] x = 144 [/tex]

Answer:

x=3

PR=10

Step-by-step explanation:

This is an isosceles triangle, indicated by the black markers on angles P and Q. This also means that sides PR and QR are equal.

That in mind, to solve for x set the two expressions equal to each other and solve for x.

3x+1=5x-5 (subtract 1 from the left side and 5 from the right. Do the same from both sides)

-2x = -6 (divide by -2)

X=3

To find the measurement for PR, simply plug in the value for x into the equation for PR

x^2 + 8x +7

Step-by-step explanation:

x times x = x^2, with 7 times x = 7x and x times 1 = 1x. Add those two common terms together to get 8x. Then lastly 7 times 1 =7 so add that.

Simplify form of (x + 1)(x + 7) is equals to x² +8x +7.

"Simplification in mathematics means to write the given expression in such a way that it is easy to understand."

According to the question,

Simplify the given equation by opening the brackets we get,

  (x + 1)(x + 7)

=  x² + 1x +7x +7

= x² + 8x + 7

Hence, simplify form of (x + 1)(x + 7) is equals to x² +8x +7.

Answer:

no

Step-by-step explanation:

bc the  x intercept is repeating when 100 is going to two numbers.A WAY easier (and faster), way to know if it is a function is to see if there are two of the same x-intercept (which make a vertical line). If there is, then it is NOT a function.

Answer:

[tex]h(x)=12x-9[/tex]

Step-by-step explanation:

We are given the two functions:

[tex]f(x)=4x-2\text{ and } g(x)=-8x+7[/tex]

And we want to find:

[tex]h(x)=f(x)-g(x)[/tex]

So, by substitution:

[tex]h(x)=(4x-2)-(-8x+7)[/tex]

Simplify. Distribute:

[tex]h(x)=(4x-2)+(8x-7)[/tex]

Rearrange:

[tex]h(x)=(4x+8x)+(-2-7)[/tex]

Combine like terms. Hence:

[tex]h(x)=12x-9[/tex]

Answer: 11

Step-by-step explanation:

From the question, we are told to calculate the value when 17 is more than -6​. This question simply means that we should add -6 and 17 together. This would then be:

= -6 + 17

= 11

Therefore, the answer is 11.

Step-by-step explanation:

1 to 9

because 1 chicken has 1 beak so the ratio of beaks is 8

1 sheep has 4 legs while 1 chicken has 2 legs

therefore multiply 4legs by 14 =56 then multiply 2 legs by 8=16

Beaks Legs

8. 72

1. 9

th ratio is therefore 1 : 9

Answer:

The equation of the function is;

y = |x-3| -3

Step-by-step explanation:

Here, we want to give the absolute-value function

For the minimum value to be -3, it means that k is negative

since the domain is the set of all real numbers, then we do not have any undefined value for the range y

So, the equation is ;

y = |x-3| - 3

Answer:

A = 2

Step-by-step explanation:

When there are no solutions for x, both sides x cancel leaving an equation with two distinct numbers equal to each other (e.g. 6 = 0). Therefore, we must find a number A for which that happens.

Lets first simplify the equation, 3Ax - 24 = 5x - 9 + x = 6x - 9.

We want to cancel out the 6x on both sides. This happens when the left side also has 6x, so 3Ax = 6x -> A = 2.

Testing out this works, we get:

6x - 24 = 6x - 9 -> -24 = -9 (which isn’t true)

We get no solutions, which is what we are looking for! Therefore, A = 2 must be our answer!

Answer:

16 cups is equal to 4 quarts

Step-by-step explanation:

Multiply the volume by 4

The required  4 quarts are equal to 16 cups. This means that if you have 4 quarts of liquid, you can pour it into 16 cups and it will completely fill them. Option D is correct.

1 quart is equivalent to 4 cups. This is a standard conversion ratio between quarts and cups. It means that if you have 1 quart of liquid and you want to know how many cups it is, you can simply multiply the number of quarts by 4.

So, to find out how many cups are in 4 quarts, we perform the following calculation:

4 quarts * 4 cups/quart = 16 cups
