Marcus is building a fence around his rectangular backyard. The length of his backyard is 75 3/4 ft, and the width is 81 1/4 ft. If the fence is 3/4 finished, how much fencing is left to complete?

Answers

Answer 1

Answer:

Step-by-step explanation:

Answer:

4,923.75ft²

Step-by-step explanation:

The area of the backyard = Length * width \

Area of the backyard = 75 3/4 * 81 1/4

Area of the backyard = 303/4 * 325/4

Area of the backyard = 6,154.6875ft²

If 3/4 of the fence is finished, the area of the finished part is expressed as;

Finished part = 1/5 * 6,154.6875

Finished part = 1,230.9375ft²

Part left unfinished = 6,154.6875-1,230.9375

Part left unfinished  = 4,923.75ft²

Answer 2

Answer: 235.5

Step-by-step explanation:

75 3/4= 75.75 (L). 81 1/4= 81.25 (W)

Perimeter= 314 3/4 of 314 is 235.5

Answer:

a. m<DAB = 36°

b. m<B = 54°

c. m<C = 74°

Step-by-step explanation:

a. m<DAB = m<CAB + m<CAD

m<DAB = 20° + 16° (substitution)

m<DAB = 36°

b. m<B = 180° - (90° + m<DAB)

m<B = 180° - (90° + 36°) (substitution)

m<B = 54°

c. m<C = 180° - (90° + m<CAD)

m<C = 180° - (90° + 16°) (substitution)

m<C = 74°

A square has side length represented by X +4 inches write an expression to represent the area. Express your answer as a trinomial.

Answers

Answer:

[tex]A=(x^2+16+8x)\ \text{inches}^2[/tex]

Step-by-step explanation:

Given that,

The side length of a square, l = (x+4) inches

We need to find an expression to represent the area of the square.

The area of a square is given by :

[tex]A=\text{side}^2[/tex]

So,

[tex]A=(x+4)^2\\\\A=(x^2+16+8x)\ \text{inches}^2[/tex]

So, the area of the square is [tex](x^2+16+8x)\ \text{inches}^2[/tex].

Please could I have the answers or step by step I don’t mind just PLEASEE help asap!!

Answers

Ok first you need to get a common denominator of 3 and 5 the smallest one would be 15 so then you rewrite both but remember if you do something to the bottom u have to do it to the top so you multiplied 3by 5 to get 15 to get your bottom then you have to times 5by 1 to get 5. So 5/15,same process for 3/5




5/15+ 9/15=9+5=14 so 14/15 (you keep the bottom the same) also it doesn’t need to be simplified because nothing can go into 14and 15 evenly





Same process for subtracting just subtract in the end so...

30/35-14/35= 16/35 also can’t be simplified evenly
In the end your answers are

1.14/15
2.16/35

Each TTF site bought a new rope bridge for 4,500. TTF will make monthly payments of $350 until the bill is paid. Write an equation for the unpaid balance B after m monthly payments

Answers

Answer: 4500 - 350m

Step-by-step explanation:

From the question, we are informed that each TTF site bought a new rope bridge for 4,500 and that TTF will make monthly payments of $350 until the bill is paid.

The equation for the unpaid balance B after m monthly payments will be:

= 4500 - 350m

where me = number of months

For example, if the number of months used is 4 months, the unique balance will be:

= 4500 - 350m

= 4500 - 350(4)

= 4500 - 1200

= 3300
