37 rounded is 40 And 51 rounded is 50 so if you round and add 40+50 or 4+5 (then add a zero) Equals 90

the length of a rectangle is 2 inches more then twice its width. find the widtg of the rectangle if the perimeter is ar least 10

Lelu [443]

Answer:

width = 16 inch.

Step-by-step explanation:

Given,

let the width be x

so, length = 2 in. more than twice its width = 2 + 2x

perimeter = 2l + 2b

we know,

perimeter = 100 in

so, 2l + 2b = 100

after inserting the values we got,

→ 2(2+2x) + 2(x) = 100

→ 4 + 4x + 2x = 100

→ 4 + 6x = 100

→ 6x = 100 - 4 = 96

→ x = 96/6 = 16

therefore, width is x so width of rectangle is 16 inch.

hope this answer helps you dear and may u have a great day ahead.

Answer:

21 of multiple choice and 17 of short answer questions

Step-by-step explanation:

Multiple choice = m
Short answer = s

Equations:

m + s = 38
2m + 3s = 93

Solve for s by eliminating m. Subtract the double of the first equation from the second one:

2m + 3s - 2(m + s) = 93 - 2(38)
3s - 2s = 93 - 76
s = 17

Find the value of m:

m = 38 - 17 = 21

Answer:

200.4 at 0.25%

Step-by-step explanation:

Given data

P= P200

r= 0.25%

t= 1 year

n= 12

A= P(1+ r/n)^nt

substitute

A= 200(1+ 0.0025/12)^12*1

A= 200(1+ 0.00020833333)^12

A= 200(1.0002)^12

A= 200* 1.002

A= 200.4

Hence the amount is 200.4 at 0.25%
