Answer: 6.5 hours

Step-by-step explanation:

You have to find out how long it’ll take, so you divide the total amount by the speed, so 455/70=6.5

Answer:

The three rules that we have are:

[tex]x^a*x^b = x^{a + b}[/tex]

[tex]\frac{x^a}{x^b} = x^{a - b}[/tex]

[tex](x^a)^b = x^{a*b}[/tex]

Then let's solve the problems:

A) 2^4 = 2^(2*2) = (2^2)^2 = 4^2 = 16.

B) 3^0 = 3^(a - a) = 3^a/3^a = 1. (for any real number a)

From this we can conclude that the power 0 of any number is equal to 1.

C)  4^6*4^(-3) = 4^(6 - 3) = 4^3 = 64

D) (2^3)^2 = 2^(3*2) = 2^6 = 64

Answer:

Step-by-step explanation:

Answer:8

Step-by-step explanation:

Answer:

Step-by-step explanation:

Given

she works $30 for 1 hour

in 40 hours she will earn 40*30= $1200

this means that a week she earns $1200

let the number of  weeks she needs to work be x

40x*(30)<=2000

1200x<=2000

x<=2000/1200

x<=1.66

the number of hours in a week is 40

40*1.66=66.66

67hours

hence she must work for at least 67hours

Answer:

160-24=x

Step-by-step explanation:

The probability that the teacher chooses two girls is 3 / 5.

Probability is defined as the ratio of the number of favorable outcomes to the total number of outcomes in other words the probability is the number that shows the happening of the event.

Probability = Number of favorable outcomes / Number of sample

Given that a teacher chooses two students in a class of 15 girls and 10 boys. The probability is calculated as:-

P = 15 / 25

P = 3 / 5

Hence, the probability is 3 / 5.

Answer:

f(-3)=-17

Step-by-step explanation:

Substitue -3 for t

-2(-3)^2 + 1

Simplify

-2(9) + 1

-18 + 1

Answer: -17

A function is defined as a relation between a set of inputs having one output each.

The value of the function f(t) = -2t² + 1 at t = -3 is -17.

The domain of the function is -17.

The range of the function is -3.

A function is defined as a relation between a set of inputs having one output each.

f(x) = x + 2

At x = 2,

f(2) = 2 + 2 = 4

Domain = 2

Range = 4

We have,

f(t) = -2t² + 1

We need to find for t = -3.

f (-3) = -2 ( -3 )² + 1

[ -3 x -3 = 9 ]

f (-3) = -2 x 9 + 1 = -18 + 1 = -17

Thus the value of the function f(t) = -2t² + 1 at t = -3 is -17.

Step-by-step explanation:

[tex]m = n + \frac{x}{p} \\ \\ \frac{x}{p} + n = m \\ \\ \frac{x}{p }= m - n \\ \\ x = m(p) - n(p) \\ [/tex]

Answer:

p(m - n) = x

Step-by-step explanation:

You want to "solve for x."  To do this, subtract n from both sides (for the purpose of isolating the x/p term):

m - n + x/p

Next, multiply all terms by p:

p(m - n) = x

Given parameters:

Real area = 9000sq yards

Map area = 6sq yards

Unknown:

Scale of the map = ?

Solution:

A scale is the ratio of the map unit to the real world expression. Maps use scales to present the real world in a smaller sample space:

   For this problem;

              6sq yards on map = 9000sq yards on ground

              1sq yards on map = xsq yards on ground

                     6x  = 9000

                         x = [tex]\frac{9000}{6}[/tex]  = 1500sq yards

So,

            1sq yards on map is 1500sq yards on ground
