Step-by-step explanation:

Answer:

p = 1.2

Step-by-step explanation:

The given equation is :

–4.6p – 6.3p + 3.9 = –9.18

Combining the like terms,

–4.6p – 6.3p = -9.18 - 3.9

−10.9p = −13.08

⇒ [tex]p=\dfrac{-13.08}{-10.9}\\\\p=1.2[/tex]

Hence, the value of p is 1.2

Answer:

The distance between Albany and Buffalo along the I90 is 288.8 mi.

The speed of Fabio is 62 mph.

After 1.5 hours, he is 221 miles from Albany.

Things we can calculate here:

Using the relation:

Distance = time*speed.

We can calculate the number of miles that he moved in that 1.5 hours.

D = 62mph*1.5h = 93mi.

If after 1.5 hours, he was 221 miles Albany, then before that he was 93 miles closer to Albany.

His initial position was:

221 - 93 = 128 miles away from Albany.

Now we also can calculate the time left to arrive at Buffalo.

We know that the distance between Albany and Buffalo is 288.8 mi

And he is 221 mi away from Albany.

Then the distance left to Buffalo is:

288.8mi - 221mi = 67.8mi

And the time left will be:

Distance/speed = time

67.8mi/62mph = 1.1 hours.

He needs to drive for another 1.1 hours to get to Buffalo.

Inequality has a set of solutions there could be infinitely many solutions to inequality.

A mathematical phrase in which the sides are not equal is referred to as being unequal. In essence, a comparison of any two values reveals whether one is less than, larger than, or equal to the value on the opposite side of the equation.

Let's consider inequality,

n > 3 where n is the natural number.

Now 4,5,6,7.... up infinite will be the solution of the inequality.

Therefore, inequality consists of infinitely many solutions.

Hence "Inequality has a set of solutions there could be infinitely many solutions to inequality".

Answer:

Cost of ride ticket = $5

Cost of game ticket = $4

Step-by-step explanation:

Given that:

Let ;

game ticket = g

Ride ticket = r

Jacob :

6g + 3r = 39 - - - (1)

Emily :

2g + 2r = 18 - - - - (2)

Divide (2) b y 2

g + r = 9 - - - - (3)

From (3)

g = 9 - r

Substitute ; g = 9 - r into (1)

6(9 - r) + 3r = 39

54 - 6r + 3r = 39

54 - 3r = 39

-3r = 39 - 54

-3r = - 15

r = 5

Put r = 5 in (g = 9 - r)

g = 9 - 5

g = 4

Hence,

Cost of ride ticket = $5

Cost of game ticket = $4

Step-by-step explanation:

You can say that the tip is ? of of 13.75 and written as

[tex]\frac{?}{13.75}[/tex] and .18 is [tex]\frac{18}{100}[/tex] cross multiply these so

13.75 x 18 = 100?

247.5 = 100?

Answer:

Si se invierten S/10 000 en acciones del tipo A, ¿cuánto de ganancia se obtendrá al cabo de seis meses?

$10,000 x 0.5% x 6 = $300

¿Cuánto se debe invertir en acciones del tipo B para que al cabo de seis meses se obtenga una ganancia de S/876,00?

interes compuesto = 0.9% trimestral

X · (1 + 0.009)² = X + $876

1.018081X = X + $876

0.018081X = $876

X = $876 / 0.018081 = $48,448.65

¿A qué tasa de interés compuesto anual la utilidad en un año es la misma para los dos tipos de acciones?

$1 x 106% = $1 x (1 + i)⁴

$1.06 = $1 x (1 + i)⁴

(1 + i)⁴ = $1.06 / $1 = 1.06

⁴√(1 + i)⁴ = ⁴√1.06

1 + i = 1.01467

i = 0.01467 = 1.467% trimestral

Answer:

3/2

Step-by-step explanation:

Because the problem tells you that the two triangles are similar, the value of a/b would be equivalent for both triangles. The fact that they are right triangles also indicates which sides are which in case the image was not drawn to scale. A is proportional to 2.1 and b is proportional to 1.4. So a/b= 2.1/1.4. This can reduce itself to 3/2 because both are divisible by .7

Answer:

y =  [tex]\frac{5}{6}[/tex]x - [tex]\frac{10}{3}[/tex]

Step-by-step explanation:

Given expression:

               5x  - 6y = 20

To solve this problem, we make y the subject of the expression:

     Solution

              5x  - 6y = 20

      Add -5x to both sides of the expression;

              -5x + 5x - 6y = 20 + (-5x)

                             -6y  = 20 - 5x

     Now, multiply both sides by [tex]-\frac{1}{6}[/tex] ;

              [tex]-\frac{1}{6}[/tex]  x (-6y) =  [tex]-\frac{1}{6}[/tex] (20 - 5x )

                         y  = [tex]-\frac{20}{6}[/tex] + [tex]\frac{5}{6}[/tex]x

                         y =  [tex]\frac{5}{6}[/tex]x - [tex]\frac{10}{3}[/tex]

Answer:

11.7 days

Step-by-step explanation:

Given that:

Filling rate = 8 quarts per hour

150 barrels picked up per trip

One barrel = 15 quarts of waste water

Barrel picked up per trip = 150 barrels

Number of quarts per barrel = 15 quarts

Total quantity of waste water = (150 * 15) = 2250 quarts

Filling rate = 8 quarts per hour

Time taken = quantity / rate

Time taken in days = 2250 quarts /(8*24) = 11.72

11.7 days

Answer:

For example, 2 + 3i is a complex number. ... The real number a is called the real part of the complex number a + bi; the real number b is called its imaginary part. To emphasize, the imaginary part does not include a factor i; that is, the imaginary part is b, not bi.

Answer:

Minimum = 55 F

Maximum = 71 F

Step-by-step explanation:

The temperature is changing by 8 degrees either up or down.

Because you don't know which way it is changing, you add and subtract to find the maximum and minimum, respectively.

63 + 8 = 71. Add for maximum.

63 - 8 = 55. Subtract for minimum.

63 min. 8 max. ?
