Step-by-step explanation:

You want triangles congruent to triangle 4.

In this exercise, we can determine congruence using SSS congruence: the lengths of the sides in congruent triangles will match. (The order of appearance of the side lengths as you go around the triangle is irrelevant.)

The lengths of the sides are ...

Looking at the other triangles, we see side lengths of ...

All side lengths match: congruent to 4.

All side lengths match: congruent to 4.

One side is 6 grid squares: not congruent.

The number of coins that the pirates collect is A. 10.

From the information, the pirate ship found a treasure chest that contained 127 gold coins and 253 silver coins and there are 38 pirates on the ship.

The number of coins that way person will get will be:

=>Total coins / Number of pirates

= (253 + 127) / 38

= 380 / 38

= 10

Answer:   A) 0.05%

Step-by-step explanation:  Converting the shaded area of the hundredths grid to a fraction would be 5/100 (or 1/20 simplified). Then convert 5/100 to a percentage by calculating 5 ÷ 100, which is 0.005%, therefor the answer is A.

The two triangles are congruent.

The number of candy bar that she bought is 6

The total amount that she spend for soda and candy= $12

The cost of one soda = $3

The cost of one candy bar = $1.50

Number of soda that she bought = 1

Consider the number of candy bar that she bought as x

Then the equation will be

3×1 + 1.50 × x = 12
Multiply the terms

3 + 1.50x = 12

Move 3 to right hand side of the equation

1.50x = 12 - 3

1.50x = 9

Move 1.50 to the right hand side of the equation

x = 9 / 1.50

x = 6

Hence, the number of candy bar that she bought is 6

The quadratic equation whose sum of two real roots is 31 and product is 210 will be [tex]x^{2} -31x+210 = 0[/tex].

According to the question,

We have the following information:

The sum of roots of a quadratic equation = 31

The product of roots of a quadratic equation = 210

We know that the standard form of the quadratic equation is given as follows:

[tex]ax^{2} +bx+c = 0[/tex]

Now, the sum of roots is -b/a and the product of roots is c/a.

So, we have the following expressions:

-b/a = 31

b = -31 and a = 1

c/a = 210

c = 210 and a = 1

So, the equation will be:

[tex]x^{2} -31x+210 = 0[/tex]

Hence, the quadratic equation whose sum of two real roots is 31 and product is 210 will be [tex]x^{2} -31x+210 = 0[/tex].

Answer:

Option (C)

Step-by-step explanation:

To simplify an expression, we can combine like terms. For this expression, there are two pairs of like terms, one-fourth y and five-twelfths y, and the constants negative seventeen and six.

To combine the fractions, we can find the least common denominator, twelve, so we can rewrite the fraction as three-twelfths.

Now combine the like terms to get eight-twelfths y minus eleven, which simplifies to two-thirds y minus eleven.

Additional comment

The standard form equation of a circle is ...

  (x -h)² +(y -k)² = r² . . . . . center (h, k), radius r

Rearranging the given equation to this form, we have ...

  (x -1)² +y² = 8 +1 = 9 . . . . . . . . r²=9 ⇒ r=3

This means the center is (1, 0), and the radius is 3. The point (1, 0) is on the x-axis.

The circle with equation x² + y² = 9 is centered at the origin and has radius 3.

The variable y varies directly with x and the variation equation is (b) y = -1/2x

The graph represents the given parameter

On the graph, we can see that:

The values of x are divided by -2 to get y

This means that the graph represents a direct variation

Recall that we stated that:

The values of x are divided by -2 to get y

This means that the constant of variation is -1/2

The direct variation equation is represented as:

y = kx

Where k represents the constant of variation i.e. k = -1/2

Substitute the known values in the above equation So, we have the following equation

y = -1/2x

Hence, the equation of variation is y = -1/2x

The constant of proportionality for the relationship is 0.002.

We are provided that amount of chlorine needed is directly proportional to the volume of the pool .

So we can formulate the relation as

C = kV ... (1)                   ( where  C = amount of chlorine ,

                                              k = constant of proportionality

                                              V = volume of the pool  )

the sample ratio of chlorine to the the volume of pool , we have :

5 : 2500

10 : 5000

15 : 7500

So taking the first sample value and putting it in eqn (1)

we get

5 = k (2500)

therefore,

k = 5/ 2500

k = 0.002

So the constant of proportionality will be 0.002

Similarly if we take the other values also the constant of proportionality will remain the same.

a ( x- - 2)(x - 5)         sub in the values of the point given (3,6) to calculate 'a'

6  = a (3+2)(3-5)

a = -6 /10 = - 3/5

y = -3/5 (x+2)(x-5)  

Answer:

[tex]\textsf{Intercept form}: \quad y=-\dfrac{3}{5}(x+2)(x-5)[/tex]

[tex]\textsf{Standard form}: \quad y=-\dfrac{3}{5}x^2+\dfrac{9}{5}x+6[/tex]

Step-by-step explanation:

[tex]\boxed{\begin{minipage}{6 cm}\underline{Intercept form of a quadratic equation}\\\\$y=a(x-p)(x-q)$\\\\where:\\ \phantom{ww}$\bullet$ $p$ and $q$ are the $x$-intercepts. \\ \phantom{ww}$\bullet$ $a$ is some constant.\\\end{minipage}}[/tex]

If the x-intercepts are (-2, 0) and (5, 0) then:

Substitute the values of p and q into the formula:

[tex]\implies y=a(x-(-2))(x-5)[/tex]

[tex]\implies y=a(x+2)(x-5)[/tex]

To find a, substitute the given point on the curve P (3, 6) into the equation:

[tex]\implies 6=a(3+2)(3-5)[/tex]

[tex]\implies 6=a(5)(-2)[/tex]

[tex]\implies 6=-10a[/tex]

[tex]\implies a=\dfrac{6}{-10}[/tex]

[tex]\implies a=-\dfrac{3}{5}[/tex]

Substitute the found value of a into the equation:

[tex]\implies y=-\dfrac{3}{5}(x+2)(x-5)[/tex]

Expand to write the equation in standard form:

[tex]\implies y=-\dfrac{3}{5}(x^2-3x-10)[/tex]

The two coordinates on the segment AB due to internal division are (5,0) and (-3,-4).

What is internal division?

When a point P divides the line joining the two points and the potint P lies in between the two coordinates then the division is internal division. If the point lies outside of the given coordinates then the division is known as external division.

The division is internally because point P lies on the line as given in the question.

The formula for the internal division is as follows:

[tex]X=\frac{mx_1+nx_2}{m+n}\\Y=\frac{my_1+ny_2}{m+n}[/tex]

Since points are A(-5,-5) and B(7,1) hence, [tex]x_1=-5,x_2=7,y_1=-5,y_2=1[/tex] and ratio is 1:5 then [tex]m=1,n=5[/tex].

Substute all value to obtain the coordinates.

[tex]X_1=\frac{1(-5)+5(7)}{1+5}\\X_1=5\\Y_1=\frac{1(-5)+5(1)}{1+5}\\Y_1=0[/tex]

Hence, the first cordinate is (5,0).

As given in the question that the ratio in not necessarily in the order of 1:5 so, consider the ratio is 5:1.

Now, m=5 and n=1.

Again substitute all values in to find the new coordinate.

[tex]X_2=\frac{5(-5)+1(7)}{5+1}\\X_2=-3\\Y_2=\frac{5(-5)+1(1)}{5+1}\\Y_2=-4[/tex]

Hence, another coordinate is (-3,-4).

Hence, the two coordinates on the segment AB due to internal division are (5,0) and (-3,-4).
