A rectangular playground has a width of 540

Mathematics
1 answer:
Nana76 [90]3 years ago
4 0

Answer: 72cm by 108cm

Step-by-step explanation:

basically, take your numbers so, 4 / 30 in a fraction form, then take a random letter, i'm using n and put n / 540 (this also will be the same for 810!)

n x 30 = 30n, 4  x 540 = 2160, divide that by 30  (which is 72) then do the SAME process but with 810 (which then you get 108) and BAM you got your answer. good luck!

Answer:

Is this what you looking for

Step-by-step explanation:

A management information base (MIB) is a database used for managing the entities in a communication network. Most often associated with the Simple Network Management Protocol (SNMP), the term is also used more generically in contexts such as in OSI/ISO Network management model. While intended to refer to the complete collection of management information available on an entity, it is often used to refer to a particular subset, more correctly referred to as MIB-module.

REBECA HAD 9/10 OF A YARDOF RIBBON. THEN SHE GAVE 7/20 OF A YARD OF FRIEND. HOW MUCH DOES SHE HAVE LEFT?
zzz [600]

Answer:

She has 11/20 yds left

Step-by-step explanation:

We take what she had and subtract what she gave away

9/10 - 7/20

We need to get a common denominator of 20

9/10 *2/2 - 7/20

18/20 - 7/20

11/20

She has 11/20 yds left

What effect does a scale factor equal to 1 have on the dimensions of the image being scaled?
FromTheMoon [43]

The scale factor equal to 1 will have No Effect on the dimensions of the image being scaled .

In the question ,

it is given that ,

the scale factor is = 1.

we have to find the effect of change ;

we know that ,

when the value scale factor is greater than 1 , then dimensions of new image is larger than original .

when the value of scale factor is 1 , then there is no change in the dimensions of the image .

when the value of scale factor is less than 1 , then the dimensions of new image is smaller than the original .

Therefore , if the scale factor is 1 , then there is no change in the dimensions of the image .

What is the best approximation of the length of segment QS? (Note: cos 80° = 0.17)
LuckyWell [14K]

Answer:

Length of the segment QS = 11.76 cm

Step-by-step explanation:

We are given with right angle triangle QRS

Angle S is 80 degree and RS = 2 cm

We need to find out QS

RS is adjacent to angle S, so we use cos formula

Cos (A) = \frac{adjacent}{hypotenuse}

Cos (S) = \frac{RS}{QS}

Plug in the angle and RS

Cos (80) = \frac{2}{QS}

Given cos(80) = 0.17

0.17= \frac{2}{QS}

Multiply by QS on both sides

0.17 * QS = 2

Divide by 0.17 on both sides

QS= 11.76470588

Length of the segment QS = 11.76 cm
