Given that :

Speed limit drops to 15 miles per hour at curve

Driver slows down by 10 miles per hour as he drives around the curve

The driver's speed before reaching the curve is :

Let speed befure curve = x

Lowest speed before curve = 15 +. 10 = 25 mph

Step-by-step explanation:

60/(v+3）=30/(v-3)

2(v-3)=v+3

2v-6=v+3

v=9

Speed is the ratio of distance and time.

It shows how fast an object is moving at a given time.

Speed = Distance / Time

The rate of the rowing team in still water is 9 miles per hour.

Speed is the ratio of distance and time.

It shows how fast an object is moving at a given time.

Speed = Distance / Time

We have,

The speed of the current:

V = 3 miles per hour

Rowed with the current:

Speed = V + 3

Distance = 60 miles

Rowing against the current:

Speed = V - 3

Distance = 30 miles

Rowing with the current and against the current took the same time.

Speed = Distance / Time

Time = Distance / Speed

Now,

Time for rowing with the current = Time for rowing against the current

60 / (V + 3) = 30 / (V - 3)

2 / (V + 3) = 1 / (V - 3)

2 (V - 3) = V + 3

2V - 6 = V + 3

2V - V = 3 + 6

V = 9

Thus,

The rate of the rowing team in still water is 9 miles per hour.

Answer: Alex is 15 years

Step-by-step explanation:

Since Alex is w years old and her sister is three years younger than him. The age of his sister will be:

= w - 3.

We will then multiply their ages and equate to 180. This will be:

w × (w - 3) = 180

w² - 3w = 180

w² - 3w - 180 = 0

w² - 15w + 12w - 180 = 0

w(w - 15) + 12(w - 15) = 0

(w + 12)(w - 15)

w - 15 = 0

w = 0 + 15

w = 15 years

Alex is 15 years, her sister is 12 years.

Answer:

1800litres

Step-by-step explanation:

Let the total litres in the tank be x

If the tank is two - thirds full of water, then the total litres initially will be 2x/3 litres

When 300 litres is used, then the remaining will be 2x/3 - 300

Equating this to half of the tank i.e x/2, we will have:

2x/3 - 300 = x/2

Collect like terms

2x/3 - x/2 = 300

Multiply through by 6

4x - 3x = 300(6)

4x-3x = 1800

x = 1800

This means that the tank can hold 1800litres of water

Answer:

true

Step-by-step explanation:

We can see why this is true by decomposing and rearranging the parallelograms into rectangles. Notice that the side lengths of each rectangle are the base and height of the parallelogram. Even though the two rectangles have different side lengths, the products of the side lengths are equal, so they have the same area!

Answer:

Step-by-step explanation:

AB+BC=AC

12+17=29=AC

Answer:

In order to solve a system of equations using elimination, you will have two equations, for example, 2x+3y=15 and x-3y=3, and for elimination, you want to find two similar terms that can be multiplied to be the same term, so 3y and -3y. YOU WILL NEED ONE TO BE POSITIVE AND ONE TO BE NEGATIVE, so you may have to multiply with a negative to get that. After you have the same terms, with different signs, you will solve, and because one is positive and one is negative, they will cancel out. The work is down below.  

Step by-step explanation:

2x+3y=15

x-3y=3

_________

3x+0=18

3x=18

x=6

in order to solve for y, you will plug x into one of the original equations!

2x+3y=15

2(6)+3y=15

12+3y=15

-12       -12

3y=3

y=1

so your systems of equations are (6,1), i hope this helps!

Answer:

Simple interest is: $2976

Account balance is: $9176

Step-by-step explanation:

First, converting R percent to r a decimal

r = R/100 = 12%/100 = 0.12 per year,

then, solving our equation

I = 6200 × 0.12 × 4 = 2976

I = $ 2,976.00

The simple interest accumulated

on a principal of $ 6,200.00

at a rate of 12% per year

for 4 years is $ 2,976.00.

Answer:

p = 4

Step-by-step explanation:

Replace the p with an 4

4p = 16

4(4) = 16

16 = 16

The equivalent value of the expression is p = 4

Given data ,

Let the equation be represented as A

Now , the value of A is

4p = 16

On simplifying the equation , we get

4p = 16

So , the left hand side of the equation is equated to the right hand side by the value of ( 16 )

Opening the parenthesis on both sides , we get

4p = 16

Divide by 4 on both sides , we get

p = 16/4

On further simplification , we get

p = 16 divided by the number 4

p = 4

Therefore , the value of p = 4

Hence , the expression is p = 4

La inclinación de la Torre de Pisa con respecto al eje vertical es 25.167º.

Step-by-step explanation:

Si tenemos una inclinación de la forma [tex]a^{\circ}\,b'\,c''[/tex] (nótese que ' y '' significan minutos y segundos, respectivamente), podemos expresarlo exclusivamente en grados sexagesimales mediante la siguiente fórmula:

[tex]x = a + \frac{b}{60} + \frac{c}{3600}[/tex] (1)

Si sabemos que [tex]a = 25[/tex], [tex]b = 10[/tex] y [tex]c = 2[/tex], entonces el ángulo expresado exclusivamente en grados sexagesimales:
