Please explain in detail with a proper answer.

A pair of dice is rolled. If you know one of the dies shows a 5, what is the probabiility that the sum is 8.

Answer:

5 days

Step-by-step explanation:

The question above is modeled by the equation :

150 − 8x = 170 − 12x.

After how many days will both have ye same amount :

Number of days = x

Collect like terms

-8x + 12x = 170 - 150

4x = 20

x = 20/4

x = 5 days

The boys will have the same amount in their account after 5 days.

Answer:

x=14

Hope This Helps!

Answer:

x = 22/3, x=14

Step-by-step explanation:

Start by isolating whatever is in the absolute value sign; in this case divide either side by 4

4|1-3/4x + 7| =10,

-----------------   ----

        4            4

|1-3/4x + 7| = 10/4 = 5/2,

now if we apply the absolute value rule we know that 1-3/4x + 7 will be equal to -5/2, and 5/2

1-3/4x + 7 = 5/2 and 1-3/4x + 7 = -5/2

-3/4x + 8 = 5/2,

-3/4x=5/2-8,

-3/4x = 5/2-16/2,

-3/4x = -11/2,

x = -11/2*-4/3 = 44/6 = 22/3

-3/4x+8 = -5/2

-3/4x = -5/2-8

-3/4x = -5/2-16/2

-3/4x = -21/2

x = -21/2*-4/3 = 82/6 = 14

Step-by-step explanation:

Answer:

Undefined

Step-by-step explanation:

To find slope, you need the difference of y over the difference of x.

For example, let's use (-8,8) and (-8,3).

Difference of y: 8-3

Difference of x: -8-(-8) (Note that the order of the x values must be the same as the order of the corresponding y values of the coordinate)

(8-3)/(-8+8)

= 5/0

Now, we see that we have to divide by 0, except it's impossible to divide by 0, so the slope is left as undefined.

Answer:

B. Yes, 3.5

Step-by-step explanation:

Proportional Variables

Two variables x,y are proportional if one of them can be calculated as the other variable time a fixed constant:

y = k.x

Or, equivalently:

k = y/x

k is called the constant of proportionality.

The table gives three points: (13,45.5) (14,49) (15,52.5)

To find out if the values correspond to a proportional relationship, we find the value of k for each pair:

k = 45.5 / 13 = 3.5

k = 49 / 14 = 3.5

k = 52.5 / 15 = 3.5

Since the value of k is the same for all the points, we conclude the table shows a direct proportional relationship and the constant of proportionality is 3.5

Taylor can clean 625 pools in 25 hours

If Taylor can clean pools at a constant rate of 25 pools per hour, this is expressed as:

25 pools = 1hour

We are to calculate the number of pools that Taylor can clean in 25 hours, this is expressed as;

x = 25 hours

Divide both expressions

25/x = 1/25

x = 25 * 25

x = 625 pools

Hence Taylor can clean 625 pools in 25 hours

The length of the base will be: 17 m

Step-by-step explanation:

Given the area of the triangle

[tex]A=102\:m^2[/tex]

Using the formula of Area of a triangle:

[tex]A=\frac{1}{2}\left(b\times h\right)[/tex]

Here,

As the base of a triangle is 7 less than twice its height.

so

[tex]b=2h-7[/tex]

so the formula of Area of a triangle becomes

[tex]102=\frac{1}{2}\left(\left(2h-7\right)\times \:h\right)[/tex]

[tex]204=h\left(2h-7\right)[/tex]

[tex]2h^2-7h=204[/tex]

[tex]2h^2-7h-204=0[/tex]

[tex]\left(2h+17\right)\left(h-12\right)=0[/tex]

[tex]2h+17=0\quad \mathrm{or}\quad \:h-12=0[/tex]

[tex]h=-\frac{17}{2},\:h=12[/tex]

As height can not be negative, so:

[tex]h=12[/tex] m

Hence, the length of the base:

[tex]b=2h-7[/tex]

   [tex]= 2(12)-7[/tex]

    [tex]=24-7[/tex]

     [tex]= 17[/tex] m

Therefore, the length of the base will be: 17 m

Answer:

~10525.41 after 7 years

Step-by-step explanation:

y=a(1+r)^x

That's the equation for exponential growth

a= the starting amount

r= the rate at which it is growing

x=years

with that information

a=7000

r=6% or 0.06

so y=7000(1+0.06)^x -> y=7000(1.06)^x

x=7

y=7000(1.06)^7

y~10525.41

Option c) [tex]0.25[/tex]

Step-by-step explanation:

[tex]p(red \cap truck) = p(red) \times p(truck)[/tex] ([tex]truck[/tex] is referring to pickup truck)

[tex]0.06=p(red) \times 0.24[/tex] (given that the probability of a red pickup truck is 0.06 and the probability of a pickup truck is 0.24)

[tex]p(red)=0.06\div0.24[/tex]

[tex]p(red)=0.25[/tex]

∴ The probability that a vehicle is red is [tex]0.25[/tex].

Answer:

The answer is 46.

Step-by-step explanation:

First, you will have to add up both functions in order to find the new expression for (g + f)(a) :

g(a) + f(a) = (g + f)(a)

(g + f)(a) = 3a + 3 + 2a - 2

(g + f)(a) = 5a + 1

Next, you have to substitute a = 9 into the function :

(g + f)(9) = 5(9) + 1

(g + f)(9) = 46

Answer:

Perimeter of sector is 47.93 cm which is greater than 47.5 cm

Step-by-step explanation:

Mathematically, the perimeter of a sector is length of the arc plus 2 radii

The length of the arc is;

theta/360 * 2 * pi * r

where theta is the angle subtended by the arc at the center of the circle

Thus, we have

135/360 * 2 * 22/7 * 11 = 25.93

Add 2 radii = 25.93 + 2(11) = 47.93 cm

This is greater than what we are asked to calculate and thus we have shown what we are asked to show

Answer:

47.9cm>47.5cm

Step-by-step explanation:

135(angle) /360 x 2 pi r (to give arc of the sector)

135/360 x 2 x 3.142 x 11 = 25.92cm

add 11 + 11 (radius)

25.92 + 22= 47.9cm

Answer:

f(x) = 2x^2 + 12x +10

Step by step solution:

x = 1 x = 5 y = 10

f(x) = a(x+1)(x+5)

f(0) = a(1)(5) = 10

5a = 10

Divide by 5

a = 2

f(x)= 2(x+1)(x+5)

f(x) = 2(x^2 +6x +5)

f(x) = 2x^2 + 12x +10
