Answer:

Option C is correct

Step-by-step explanation:

In similar triangles corresponding sides are in same ratio.

Notice that  sides b and q are corresponding ( they are opposite equal angles)  and so are a and p

The correct equation from the option is b/q = a/p. Hence, option C is correct.

To make a proportional relationship from the two triangles ABC and PQR given ;

Express corresponding sides as ratios ;

Answer:

Step-by-step explanation:

Simplify 1/3x to x/3

y = -x/3 - 9

Add 9 to both sides

y + 9 = -x/3

Multiply both sides by 3

(y + 9) * = -x

Regroup terms

3(y + 9) = -x

Using the formula, rewrite in standard form

Answer: x + 3y = -27

To convert the equation y = -1/3x - 9 to standard form, you need to eliminate the fraction and rearrange the equation. Multiply both sides of the equation by 3 to get 3y = -x - 27. Rearrange the equation to get x + 3y = -27, which is the standard form.

The equation y = -1/3x - 9 can be written in standard form as Ax + By = C, where A, B, and C are constants. To write the equation in standard form, we need to eliminate the fraction by multiplying both sides of the equation by 3. This gives us 3y = -x - 27. Rearranging the equation, we get x + 3y = -27, which is the standard form.

A is your answer because 4×1=4 so it means that it is thedistributive property

Answer:

60 degree

Step-by-step explanation:

adding 1 both sides of equation

2cos x -1+1 = 0.0068 +1

2cosx = 0.9932

dividing by 2 both sides

cosx = 0.9932 / 2

cosx =0.4966

x= cos^-1(0.4966)

Convert all statistics into percentages:

CA: 3/25=0.12 -> 12%

(A) Out of the three states, California has the largest population

(B) Out of the three states, NY has the smallest population

(C) USA=100%, CA+NY+TX=26%, therefore 74% of USA do not live on those three states.  

The equation is: 7 + (x + 5)

The expression for '7 plus the sum of a number x and 5' is written as '7 + (x + 5)'.

The phrase '7 plus the sum of a number x and 5' can be written as an algebraic expression. This involves taking the sum of the variable x and the number 5, and then adding 7 to this sum. In mathematical terms, this is expressed as 7 + (x + 5).

Let's break it down step by step:

First, identify the sum: x + 5.

Next, add 7 to the result of this sum.

So, if we were to evaluate this expression for x = 4, we would calculate it as follows:

7 + (4 + 5) = 7 + 9 = 16

We are given that

y-scale is a distance in miles

x-scale is a time in hours

and we are given

The graph of the distance a car travels at a constant speed passes through the points (0,0) and (2,136)

so, points would be

(0,0)

x1=0 , y2=0

(2,136)

x2=2 , y2=136

so, slope would be speed

because speed = distance / time

we can use slope formula

[tex]m=\frac{y_2-y_1}{x_2-x_1}[/tex]

now, we can plug values

[tex]m=\frac{136-0}{2-0}[/tex]

[tex]m=68[/tex] miles per hour

You can use the given distance to amount of gasoline used relationship to find how much gasoline is needed for 1 km of traveling. Then use that data to find the amount of gasoline needed to travel 500 km.

The amount of gasoline needed to travel 500 km is 40 L

We can equate the 150 km figure to 12 L use of gasoline on the basis of usage.

Thus,

[tex]\rm 150 \: km = 12 \: L\\\\\\\text{Dividing both quantities in 150 parts}\\\\\\dfrac{150}{150} \: km = \dfrac{12}{150} \: L\\\\1 \: km = 0.08 \: L[/tex]

Thus, there will be use of 0.08 L gasoline for travelling 1 km by that same car.

Using that above derived relationship, we can find the amount of gasoline needed to travel 500 km by that same car.

[tex]1 \rm \: km = 0.08 \: L\\\\\text{Multiplying 500 on both the sides}\\\\500 \: km = 40 \: L[/tex]

Thus,

The amount of gasoline needed to travel 500 km is 40 L

A I think

it could be wrong though

Answer:

5 adult and 3 student tickets were purchased

Explanation:

Let x be the number of adult tickets

Then 8−x is the number of student tickets

7.25x+5.5(8−x)=52.75

7.25x+44−5.5x=52.75

1.75x=8.75

x=5

Therefore, 5 adult and 3 student tickets were purchased.

80 = 3y + 2y + 4 +1

80 = 5y + 5

80 - 5 = 5y

75 = 5y

75 = 5y/5y

75/5 = y

Step-by-step explanation:

Given : The distance from the earth to the sun is 9.3×10 to the 6(power) miles. The distance from earth the moon is 3×10 to the 5th(power) miles.

To find : How many times bigger is the distance from earth to the sun than the distance from earth to the moon?

let y = x^2

4y^2 -21y + 20 = 0

solve for y

then substitute back in to get x

Answer:

4y^2 - 21y + 20 = 0

Step-by-step explanation:

As (4x^4 - 21x^2 + 20=0) being a biquadratic equation, meaning it is a 4-degree equation without the terms of degree 1 and 3.

To solve this particular case you only need to replace the variables of degree 4 and 2 for a new variable of degree 2 and 1 and solve it as regular quadratic equation and then undo the change.

* Using a new variable we can rewrite the equation:

Let y be the new variable;

y= x^2, then y^2= x^4

Then we have;

4y^2- 21y+20=0

Solve for y and then find X which will be the roots for the biquadratic equation.

Given the speed is 200 km /hr

Answer:  C) 55.6 m/s

Answer:

We have

k^2 - 25f^2 + 5kf - 25f^2 =

k^2 - (5f)^2 + 5f( k - 5f) =

( k - 5f )( k + 5f ) + 5f( k - 5f ) =

( k - 5f )( k + 5f + 5f ) =

( k - 5f )( k + 10f );

Step-by-step explanation:

Answer:  The required factored form of the given expression is [tex](k-5f)(k+10f).[/tex]

Step-by-step explanation:  We are given to factor the following quadratic expression :

[tex]E=k^2+5kf-50f^2~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~(i)[/tex]

To factor the given expression, we need two integers with sum 5 and product -50 and those two integers are 10 and -5.

The factorization of expression (i) is as follows :

[tex]E\\\\=k^2+5kf-50f^2\\\\=k^2+10kf-5kf-50f^2\\\\=k(k+10f)-5f(k+10f)\\\\=(k-5f)(k+10f).[/tex]

Thus, the required factored form of the given expression is [tex](k-5f)(k+10f).[/tex]

Because there are 2 minus signs next to each other, we can replace both of them with a single plus sign.

This changes the equation to -7 + 3

Adding to a negative number makes the number appear smaller, so 3 + -7 = -4.

Remove parenthesis

-7=3

Calculate the sum

The expression 6a − 3b = 5b after solving for a:b is 4:3 after using arithmetic operation.

It is described as the comparison of two quantities to determine how many times one obtains the other. The proportion can be expressed as a fraction or as a sign: between two integers.

It is given that:

The expression is:

6a − 3b = 5b

To solve the above expression:

6a = 5b + 3b

6a = 8b

a/b = 8/6

As we know,

The expression can be defined as the combination of constants and variables with mathematical operators.

a:b = 8: 6

a:b = 4: 3

If in the linear expression, one variable is present, then the expression is known as the linear expression in one variabe.
