3) There are 12 inches in a foot, so 144/12 equals 12 feet- the distance above the floor. 12 goes into 40 about 3 times. 3 feet + 12 feet equals about 15 feet.

4) When you want to find the percentage of something, you would take the percentage and move the decimal place two spaces to the left. So 45% becomes .45. Then you would multiply that by the number of houses. .45 times 36 equals 16.2. Rounded to the nearest whole number, 16 houses display holiday lighting.

Solve the following formula for t.<br> A= J(1 + rt)
Lubov Fominskaja [6]

Explic

Pasos para resolver una ecuación linea

A=J(1+rt)

Usa la propiedad distributiva para multiplicar J por 1+rt.

A=J+Jrt

Intercambie los lados para que todos los términos de las variables estén en el lado izquierdo.

J+Jrt=A

Combina todos los términos que contienen J.

(1+rt)J=A

La ecuación está en formato estándar.

(rt+1)J=A

Divide los dos lados por 1+rt.

rt+1(rt+1)J=rt+1A

Al dividir por 1+rt, se deshace la multiplicación por 1+rt.

J=rt+1A

A community group is picking up trash along a portion of the highway that is 1.48 miles long. In one hour they can clean a secti
aleksklad [387]

Answer:

12 if im correct

Step-by-step explanation:

first we have to see that they are doing 1/8 of a mile per hour so if we divide 1.48 by 1/8 it should give us the time

first we convert 1/8 to a decimal which is .125 and we divide 1.48 by .125

giving us 11.84

since it is time, 11 hrs would be too little of a time so we need to round up to 12

Hope thats right

The number of exports is shown as g(x). Use the data in the table below, representing both functions, to explain to your boss th
siniylev [52]

Step-by-step explanation:

Given the table:

Month              f(x) = Number of imports    g(x) = Number of exports

January (1)                3                                                1

February (2)             4                                                3

March (3)                  5                                                5

April (4)                     6                                                7

From the table, it is clear that:

Number of imports = number of month + 2

so

f(x) = x + 2

also

Number of exports  = 2(number of month) + 1

so

g(x) = 2x - 1

Therefore, number of imports equals the number of month plus one. i.e. f(x) = x + 2, which is a linear function.

If we compare it with slope-intercept form of the line

y=mx+b

Then,

slope = m = 1

y-intercept = 2

Also number of exports equals is also a linear function.

i.e. g(x) = 2x - 1

Here,

slope = m = 2

y-intercept = -1

Ms. Fox loves to eat cereal and she notices that she only has 1/3 of the box of cereal left. If she spread that amount across 5
IceJOKER [234]

Answer:

1/15

Step-by-step explanation:

Ms. Fox loves to eat cereal and she notices that she only has 1/3 of the box of cereal left. If she spread that amount across 5 days, how much cereal will she have for each day?

The amount of cereal she would have per day is calculated as:

5 days = 1/3 of the box

1 day = x

Cross Multiply

5 days × x = 1 day × 1/3 of the box

x = 1/3 ÷ 5

x = 1/3 × 1/5

x = 1/15 of the box
