Answer:

Length = 75 ft

Step-by-step explanation:

Area = 300 ft²

Height = 4 ft

Finding the length:

Area = Length * Height

Assembling the formula for Length

Length = $\frac{Area}{Height}$

Length = $\frac{300}{4}$

Length = 75 ft

A teacher is four time as old as a student .in 20 years, the student 's age will be half of the teacher 's age. How old are they

notka56 [123]

Let the present age of student be x
Present of teacher will be 4x

After 20 years,
Age of student = x + 20
Age of teacher = 4x + 20

According to the given condition after 20 years,
x + 20 = (4x + 20)/2
x + 20 = 2x + 10
2x - x = 20 - 10
x = 10

So student's present age is 10 years while teacher's is 4 x 10 i.e 40 years.

The distance from Gary's school to the corner market is 47 yards.The distance to the BART station is 12 times as far How far is

andre [41]

Answer:

The distance from Gary's school to the BART station is 564 yards

Step-by-step explanation:

Let

x ----> the distance from Gary's school to the corner market

y ----> the distance from Gary's school to the BART station

we have

$x=47\ yd$

we know that

To find out the distance from Gary's school to the BART station, multiply the distance from Gary's school to the corner market by 12

$y=12x$

substitute the value of x

$y=12(47)=564\ yd$

therefore

The distance from Gary's school to the BART station is 564 yards

if log 2 = ( 0.3010 ), Log 3 = ( 0.4771 ) and Log 5 = ( 0.6990 ) then find the value of the following: Log 24... The answer is (

tekilochka [14]

Answer: 1. 3801

Step-by-step explanation:

Log 24 = Log(8x3)

From the laws of Logarithm

Log ( a xb) = Log a + Log b

so, Log (8x3) = Log8 + Log 3

Also Log 8 can be written as Log $2^{3}$ since $2^{3}$ is still 8 , so the expression becomes

Log $2^{3}$ + Log 3

⇒ 3 Log 2 + Log 3

since the value of Log 2 and Log 3 has been given , substitute into the expression , we have

3 (0.3010) + 0.4771

= 0.903 + 0.4771

= 1.3801
