( brainlies ) Can somebody help me with this?
Gekata [30.6K]

Answer:
(a)

Area: 930 meters(m)

Perimeter: 122 meters(m)

(b)

Area: 616 centimeters(cm)

Perimeter: 116 centimeters(cm)

(c)

Area: 1008 millimeters(mm)

Perimeter: 128 millimeters(mm)

Explanation:

Area = length x width

Perimeter = length+width+length+width

Area for (a) is then 31 times 30 = 930
Area for (b) is then 44 times 14 = 616
Area for (c) is then 36 times 28 = 1008

Perimeter for (a) is 31+30+31+30=122

Perimeter for (b) is 44+14+44+14=116

Perimeter for (c) is 36+28+36+28=128

Bank a charges a six dollar service fee and $.10 for each check written. Bank be charges $5.20 for each check written how many c
Elden [556K]

Answer:

A person needs to write each month 1.17 checks for the two banks to charge the same amounts in fees.

Step-by-step explanation:

You can write an equation in which the amount charged by bank a is equal to the amount charged by bank b. The amount bank a charges is 6 plus 0.10 for the number of checks written and the amount bank b charges is 5.20 for the number of checks written.

6+0.10x=5.20x, where x is the number of checks written

Now, you can solve for x to find the number of checks written where the two banks charge the same amounts in fees:

6=5.20x-0.10x

6=5.10x

x=6/5.10

x=1.17

According to this, the answer is that a person needs to write each month 1.17 checks for the two banks to charge the same amounts in fees.

Help please !!!!!!!!!!!!!!!!!!
Hunter-Best [27]

Answer:

n = 59

Step-by-step explanation:

There's definitely a better way, i just did math randomly but here goes:

First i squared both sides. which gets you:

(\sqrt{n+5}-\sqrt{n-10} )(\sqrt{n+5}-\sqrt{n-10} )=1^2\\\\n+5 -2\sqrt{(n+5)(n-10)} +n-10=1

Cleaning this up gives you:

2n-5 -2\sqrt{(n+5)(n-10)}=1

Now move everything to the other side so we can square this equation again

-2\sqrt{(n+5)(n-10)}=-2n+6

Divide both sides by -2

\sqrt{(n+5)(n-10)}=n-3

square again

(n+5)(n-10)=(n-3)^2\\n^2-5n-50=n^2-6n+9

subtract n^2 from both sides, add 6n, and add 50

-5n-50=-6n+9\\n-50 = 9\\n=59

Put this back into the equation and you get a correct answer!

sqrt(59 + 5) = sqrt(64) = 8

sqrt(59-10) = sqrt(49) = 7

8 - 7 = 1

5 ^6 − 5 ^11 = 5 x ( 1 − 5 y ) what is the value of x and y
Eva8 [605]
Is it 5^6 - 5^11 = 5x × (1-5y)?
5^6 - 5^11 = 5^(6-11) = 5^(-5) = 1/(5^5)
So 1/3125 = 5x - 5(5y)
1/3125 = 5(x-5y)
1/3125/5 = x-5y
0.000064 = x - 5y
