Step-by-step explanation:

first pay 100 = second pay 60

first pay ( 100 / 60 ) = second pay 1

first pay ( 100 / 60 ) * 36 = second pay 36

first pay 60 = second pay 36

[ Note : ( 100 / 60 ) * 36 = 60 ]

the one you have circled is correct

Step-by-step explanation:

Answer:

The fourth answer selection is the correct

Step-by-step explanation:

Yes, the two triangles have to sides and the angle in between congruent, so by the SAS theorem, they are congruent.

Therefore select the fourth option that gives the order of vertices of the second triangle similar to the order of vertices in the first one :

Triangle YXW  by SAS.

Notice that side YX is congruent to side QR,

and side RS is congruent to side SW.

Answer:

The tortoise can walk 0.25 feet per second.

Step-by-step explanation:

Convert inches to feet

Answer:

A tortoise walks 3 inches in 1 second. How many feet per second can the tortoise walk?

To answer the question, you need to write a conversion factor to convert  

inches to feet

The correct conversion factor has the inches in the  

denominator

The correct conversion factor has the feet in the  

numerator

.

The tortoise can walk  

0.25

feet per second.

If the train travels 744 miles in 3 hours then to determine the unit rate the train is traveling per hour you have to divide the miles by the hours, in this case (744 miles)/(3 hours). The final result concludes as 248 miles per hour.

Answer:

Step-by-step explanation:

∠4 + ∠3 = 180

40 + ∠3 = 180

∠3 = 180 - 40

∠3 = 140

Answer:=42 cm

Step-by-step explanation:

Strap=(a+b)*h/2    ( where a and b are trapezoid' s  bases and h is a height)

So   864=(30+b)*24/2

30+b=864*2/24

30+b=864/12

30+b=72

b=72-30

b=42 cm

Answer:

The coefficient of [tex]x^{4}[/tex][tex]y^{3}[/tex] is -280

Step-by-step explanation:

Solving the Binomial expansion using the Pascal's triangle, it would be observed that an expansion to the power of 7 can be solved using;

1  7  21  35  35  21  7  1

Thus;

[tex](x - 2y)^{7}[/tex] = 1. [tex]x^{7}[/tex] + 7.[tex]x^{6}[/tex](-2y) + 21.[tex]x^{5}[/tex][tex](-2y)^{2}[/tex] + 35.[tex]x^{4}[/tex][tex](-2y)^{3}[/tex] + 35.[tex]x^{3}[/tex][tex](-2y)^{4}[/tex] + 21.[tex]x^{2}[/tex][tex](-2y)^{5}[/tex] + 7.x[tex](-2y)^{6}[/tex] + [tex](-2y)^{7}[/tex]

        = [tex]x^{7}[/tex] -14[tex]x^{6}[/tex]y +84[tex]x^{5}[/tex][tex]y^{2}[/tex] -280[tex]x^{4}[/tex][tex]y^{3}[/tex] + 560[tex]x^{3}[/tex][tex]y^{4}[/tex] - 672[tex]x^{2}[/tex][tex]y^{5}[/tex] + + 448x[tex]y^{6}[/tex] - 128[tex]y^{7}[/tex]

Therefore, the coefficient of [tex]x^{4}[/tex][tex]y^{3}[/tex] is -280

Answer:

2 i think

Step-by-step explanation:

Answer:

The types of slope for each pair are:

(2, 4) and (5, 1) => Negative

(3,5) and (-1,2) => Positive

(-7, 8) and (-7,0) => Undefined

(6.-3) and (4, -3) => Zero

Step-by-step explanation:

We will find the slope of each line to check the type of slope.

Slope is given by the formula:

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

Here (x1,y1) are the coordinates of first point and (x2,y2) are coordinates of second point

Now,

(2, 4) and (5, 1)

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

The slope is negative.

(3,5) and (-1,2)

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

The slope is positive

(-7, 8) and (-7,0)

[tex]m = \frac{0-8}{-7+7} = \frac{-8}{0}[/tex]

division by zero makes the slope undefined.

(6.-3) and (4, -3)

[tex]m=\frac{-3+3}{4-6} = \frac{0}{-2} = 0[/tex]

The slope is zero

Hence,

The types of slope for each pair are:

(2, 4) and (5, 1) => Negative

(3,5) and (-1,2) => Positive

(-7, 8) and (-7,0) => Undefined

(6.-3) and (4, -3) => Zero

Answer:b

Step-by-step explanation:

Answer:

x = 45

y = 60

z = 75

Step-by-step explanation:

We can create three different equations with the given variables:

x + y + z = 180

y + z = 3 x

z = y + 15

then we can use this last equation to substitute for 'z" in the second equation:

y + z = 3x

y + y + 15 = 3 x

2 y + 15 = 3 x

x = 2/3 y + 5

Then we can re-write the first equation in terms of y and solve for this unknown:

2/3 y + 5 + y + y + 15 = 180

2/3 y + 2 y = 160

8/3 y = 160

y = 3 * 160 /8

y = 60

Then   x = 2/3 (60) + 5 = 45

so x = 45

and finally:   z = 60 + 15 = 75

so  z = 75

You could say "7328 dollars and 42 cents", but the shorter format is preferred in my opinion.

====================================

Work Shown:

A = P*e^(r*t)

A = 6000*e^(0.04*5)

A = 7328.41654896153

A = 7328.42

The symbol 'e' is a special number in math similar to how pi = 3.14 is another important symbol. If your calculator doesn't have a button labeled 'e', then replace 'e' with 2.718 to use its approximation.

Answer:

3.33in x3.83in

Step-by-step explanation:

Hello there pm34080075, I'm going to assume you are referring to a 19 ft 12in by 22ft 12in. If this is incorrect I will write out the steps so it should be an easy fix. The simplest thing we can do is convert all of our units to inches and then set up a ratio to find the dimensions on the blueprint.

With what we are given it should turn out to be roughly:

19ft 12in= 240in

22ft 12in= 276in

From this we can set up the simple ratio of [tex]\frac{1inch}{72in}[/tex] to find out the appropriate values This can be done by solving for x in:

[tex]\frac{1 inch}{72in}[/tex]  x  [tex]\frac{x}{240in}[/tex]

and

[tex]\frac{1 inch}{72in}[/tex]  x  [tex]\frac{x}{276in}[/tex]

After this is done we find that the dimensions on the blueprint will come out to 3.33in x3.83in

Hope this helps!

Answer:

The answer is C.

Step-by-step explanation:

Answer:

No she isn't. The value of [tex]a[/tex] is [tex]a=-\frac{1}{45}[/tex]

Step-by-step explanation:

We know that all quadratic equation can be written in the following way :

[tex]y=ax^{2}+bx+c[/tex] (I)

Where [tex]a,b[/tex] and [tex]c[/tex] are real numbers.

I will attach a drawing with the quadratic graph to understand the situation.

We know by looking at the drawing and analyzing it that the parabola passes through the points : [tex](0,0) ; (60,80)[/tex] and [tex](120,0)[/tex]

[tex](0,0)[/tex] because we put our coordinates origin there.

[tex](120,0)[/tex] because that's where the golf hole is.

And [tex](60,80)[/tex] because we know that its highest point reaches 80 feet up in the air at the middle of the distance between its roots (property of a negative parabola).

Finally, we work with the three points and the equation (I) in order to find the values of [tex]a,b[/tex] and [tex]c[/tex] ⇒

The parabola passes through [tex](0,0)[/tex] ⇒

[tex]y=ax^{2}+bx+c[/tex] ⇒

[tex]0=a(0)^{2}+b(0)+c[/tex] ⇒ [tex]c=0[/tex]

The parabola passes through [tex](60,80)[/tex] ⇒

[tex]80=a(60)^{2}+b(60)[/tex] ⇒

[tex]80=3600a+60b[/tex] (II)

The parabola passes through [tex](120,0)[/tex] ⇒

[tex]0=a(120)^{2}+b(120)[/tex] ⇒

[tex]0=14400a+120b[/tex]

[tex]120b=-14400a[/tex]

[tex]b=-120a[/tex] (III)

Now if we use (III) in (II) ⇒

[tex]80=3600a+60(-120a)[/tex]

[tex]80=3600a-7200a[/tex]

[tex]3600a=-80[/tex]

[tex]a=-\frac{1}{45}[/tex]    ⇒ [tex]b=\frac{8}{3}[/tex]

Finally the equation of the parabola is

[tex]y=-\frac{x^{2}}{45}+\frac{8}{3}x[/tex]

Where the value of [tex]a[/tex] is [tex]a=-\frac{1}{45}[/tex]
