Your problem → 5y+5/2 / 25y-20/40y^2-32y

5y+5/2÷25y-20/40y^2-32y

=5⋅y+5/2÷25×y-20/40×y^2-32×y

=5y+5/2÷25×y-20/40×y^2-32y

=5y+5/2×1/25×y-20/40×y^2-32y

=5y+y/10-20/40×y^2-32y

=5y+y/10-y^2/2-32y

=5y×10+y-y^2×5-32y×10 ÷ 10

=50y+y-5y2-320y ÷ 10

= -269y-5y^2 / 10

Answer:

Step-by-step explanation:

We need to find whether the two given triangles are congruent.

The given triangles are congruent.

The distance between two points is given by

[tex]d=\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}[/tex]

A(2,-8) and B(-5,-2)

[tex]AB=\sqrt{(-5-2)^2+(-2-(-8))^2}\\\Rightarrow AB=\sqrt{49+36}\\\Rightarrow AB=\sqrt{85}[/tex]

D(-9,7) and E(-11,12)

[tex]DE=\sqrt{(-11-(-9))^2+(12-7)^2}\\\Rightarrow DE=\sqrt{29}[/tex]

B(-5,-2) and C(-7,3)

[tex]BC=\sqrt{(-7-(-5))^2+(3-(-2))^2}\\\Rightarrow BC=\sqrt{29}[/tex]

E(-11,12) and F(-2,1)

[tex]EF=\sqrt{(-2-(-11))^2+(1-12)^2}\\\Rightarrow EF=\sqrt{202}[/tex]

A(2,-8) and C(-7,3)

[tex]AC=\sqrt{(-7-2)^2+(3-(-8))^2}\\\Rightarrow AC=\sqrt{202}[/tex]

D(-9,7) and F(-2,1)

[tex]DF=\sqrt{(-2-(-9))^2+(1-7)^2}\\\Rightarrow DF=\sqrt{85}[/tex]

It can be seen that [tex]AB=DF=\sqrt{85}[/tex], [tex]BC=DE=\sqrt{29}[/tex] and [tex]AC=EF=\sqrt{202}[/tex].

Since, each side of triangle ABC is equal to one side of triangle DEF they are congruent to each other.

Answer:

Choice B

Step-by-step explanation:

He is currently 40 inches in height.

He needs to be 48 inches in height to ride the roller coaster.

He is growing 1.2 inches per month (m)

So, 40 + 1.2m ≥ 48

40 inches + average gain per month has to be greater or equal to (≥) 48 inches.

Answer:

they sold 210 hot chocolates and 85 coffees

Step-by-step explanation:

We know that they sold $200 worth of drinks

x will be the number of hot chocolates sold

y will be the number of coffees sold

This means that

.75x+.5y=200

We also know that they sold 295 total drinks which means that

x+y=295

This is a system of linear equations which I will solve through substitution

x+y=295

Subtract y from both sides and divide by -1 to get

-x+295=y

Plug y into the first equation and get

.75x+.5(-x+295)=200

Distribute the .5 and simplify to get

.75x-.5x+147.5

.25x+147.5=200

Subtract 147.5 and then divide by .25 to get our x value

x=210

Now we can go back and plug this in into our equation

210+y=295

Subtract 210 to get y

y=85

This means that they sold 210 hot chocolates and 85 coffees

Answer:

Absolute change = 3%

Relative change = 100%

Step-by-step explanation:

Current percentage = 3%

Upcoming percentage = 6%

Absolute change :

Relative change :

Absolute change = (upcoming percentage - current year percentage)

Absolute change = 6% - 3% = 3%

Relative change :

[(upcoming percentage - current year percentage) / current year percentage] * 100%

[(6% - 3%) / 3%] * 100%

(3% / 3%) * 100%

1 * 100%

= 100%

Answer:

It will cost her $27 to drive 336 miles.

Step-by-step explanation:

With the information provided, you can use a rule of three to find how much it will cost to drive 336 miles given that driving 28 miles costs $2.25:

28 miles     →    $2.25

336 miles    →         x

x=(336*2.25)/28= 27

According to this, the answer is that it will cost her $27 to drive 336 miles.

Answer: b and d

Step-by-step explanation:

Answer:

y = x + 1

Step-by-step explanation:

1) First, find the slope of the line between the two points. Whichever option has the same slope would be the right answer. To find this, use the slope formula [tex]\frac{y_2-y_1}{x_2-x_1}[/tex]. [tex]x_1[/tex] and [tex]y_1[/tex] represent the x and y values of one point, and [tex]x_2[/tex] and [tex]y_2[/tex] represent the x and y values of another point.

So, use the points given to answer the question. Substitute 4 for [tex]x_1[/tex], 5 for [tex]y_1[/tex], 8 for [tex]x_2[/tex], and 9 for [tex]y_2[/tex] then solve:

[tex]\frac{(9)-(5)}{(8)-(4)} \\= \frac{9-5}{8-4} \\= \frac{4}{4} \\= 1[/tex]

Therefore, the slope is 1.

2) Any line that is in a "y = a number" format is a horizontal line, and all horizontal lines have a slope of 0 - so the second option can't be the answer.

The rest of the options are in slope-intercept form, or y = mx + b format. Remember that the coefficient of the term with the x is the slope. Knowing this, y = x + 1 would need to be the answer since the coefficient of the term with the x is 1, and we already calculated that the slope is 1.

Answer:

Emmanuel will walk 510 miles in 1.7 hours.

Step-by-step explanation:

Given that Emmanuel walks at an average speed of 5 m/min.

It means:

As there are 60 minutes in 1 hour.

so

1.7 hours = 102 minutes

Thus,

The walking distance in 102 minutes = 5 × 102

                                                             = 510 miles     ∵ 1 min = 5 miles

Therefore, Emmanuel will walk 510 miles in 1.7 hours.

Answer:

If using simple interest, the formula is:

= Amount * ( 1 + rate * time)

= 20,000 * ( 1 + 4% * 5)

= $24,000

Interest = Balance after 5 years - Investment

= 24,000 - 20,000

= $4,000

Using Compound Interest:

= Amount * ( 1 + rate)^time

= 20,000 * ( 1 + 4%)⁵

= $24,333.06

Interest = 24,333.06 - 20,000

= $4,333.06
