5 The area of a rectangular lawn is 255 m². If its length is 15 m, find its perimeter.​

Answers

Answer 1
Area of a rectangular lawn = l×b

255=15×x

Hence the breadth is 17 m

Hence perimeter =2(l+b)=2(15+17)=64

What is expression?

Expressions is the defined as mathematical statements that have a minimum of two terms containing variables or numbers.

What are Arithmetic operations?

Arithmetic operations can also be specified by the subtract, divide, and multiply built-in functions.

The operator that perform arithmetic operation are called arithmetic operators .

Operators which let do basic mathematical calculation

+ Addition operation : Adds values on either side of the operator.

For example 4 + 2 = 6

- Subtraction operation : Subtracts right hand operand from left hand operand.

for example 4 -2 = 2

* Multiplication operation : Multiplies values on either side of the operator

For example 4*2 = 8

/ Division operation : Divides left hand operand by right hand operand

For example 4/2 = 2

Given expression as :

⇒ m + 5q

where m = 1, and q = 5

Substitute the values of m = 1, and q = 5 in the expression and apply the arithmetic operations

⇒ 1 + 5(5)

⇒ 1 + 25

⇒ 26

Hence, the solution of m + 5q is 26, where m = 1, and q = 5.

Any helppp pLeAsE? T^T

Answers

answer:

c = 7.6 kilometers

step-by-step explanation:

you can use the pythagorean theorem for this since this is a right triangleknow the formula: a^2 + b^2 = c^2

now plug in what we know, also remember:

a = legb = the other legc = hypotenuse

a^2 + b^2 = c^2

3^2 + 7^2 = c^2

9 + 49 = c^2

58 = c^2

c = 7.6157

rounded: c = 7.6 kilometers

Find the value of r so the line that passes through each pair of points has the given slope.
(1, r), (7, 5), m = 2/3

Answers

Answer:

r = 1

Step-by-step explanation:

slope = change in y / change in x, so:

change in y / change in x  = 2/3

5 - r / 7 - 1 = 2/3

5 - r / 6 = 2/3

[tex]\frac{5-r}{6}=\frac{2}{3}[/tex]

now solve this equation.

first, multiply both sides by 6 to get rid of the fraction:

subtract 5 from both sides

Answer:

3 pieces

Step-by-step explanation:

Given: Figure

To find: Number of 8.5 in. ×  11 in. pieces used to cover the floors  of a room and a hallway in  her dollhouse

Solution:

In the given figure, AC = 22 in.

AB + BC = 22 in.

AB + EF = 22 (As BC = EF being opposite sides of rectangle)

AB + 10 = 22

AB = 22 - 10 = 12 in.

Area of rectangle ABGH = AB × AH = 12 × 5 = 60 square inches

(area of rectangle = length × breadth )

CE = CD + DE = AH + GF (As CD = AH and DE = GF)

CE = 5 + 15 = 20 inches

Area of rectangle BCEF = BC × CE = 10 × 20 = 200 square inches

(BC = EF = 10 in.)

Total area of the figure = Area of rectangle ABGH + Area of rectangle BCEF = 60 + 200 = 260 square inches

Area of pieces of felt = 8.5 × 11

So,

Number of pieces required = Total area of the figure / Area of pieces of felt  =   3 pieces

Answer:

[tex]x=\frac{21}{4}[/tex]

Step-by-step explanation:

equation (1): [tex]\frac{1}{2} (2x+y)=\frac{21}{2}[/tex]

equation (2): y=2x

solve the system by substitution

step1: sub (2x) for y in equation 1:

[tex]\frac{1}{2} (2x+y)=\frac{21}{2}[/tex]

[tex]\frac{1}{2} (2x+2x)=\frac{21}{2}[/tex]

step2: simplify the expression:

[tex]2x=\frac{21}{2}[/tex]

(divide by 2 for both sides)

[tex]x=\frac{21}{4}[/tex]

To find the value for y sub 21/4 for x in equation 2:

y=2x

y=2×(21/4)
