If the perimeter of the rectangle is 6x+c what is the value of c

What would the first step be in solving the inequality: -y (less than or greater than sign) 136

Alex73 [517]

"-y (less than or greater than sign) 136" translates into two separate inequalities:

-y < 136 and -y > 136.

You want to solve for y in each case. To do this, multiply each inequality by "-1" and then immediately change the direction of the inequality sign.

For example: -1(-y < 136) => y > -136.

There are 63 students in band. This represents 30% of the grade. How many students are in the entire grade

almond37 [142]

So, the question is 63 is 30% of what number?

That can translate to the equation

63 = 30% · x or 63 = 0.3x

Divide by 0.3 and you get x = 210.

There are 210 students in band.

6. a) Calculate the areas of the three squares. b) Is the triangle a right triangle? Explain. 3 cm 4 cm 2 cm

viktelen [127]

Answer

The total area of the squares = 29 square cm

The triangle is not a right-angled triangle

Step-by-step explanation:

We are given three squares

The first square has a length of 4cm

The second square has a length of 3cm

The third square has a length of 2cm

Part A

Total area = Area of square 1 + Area of square 2 + Area of square 3

Area of a square = l^2

Where l is the length of the square

Area of a square 1 = 4^2

Area of a square = 16 square cm

Area of square 2 = 3^2

Area of square 2 = 9 square cm

Area of square 3 = 2^2

Area of square 3 = 4 square cm

Total area of the square = 16 + 9 + 4

The total area of the square = 29 square cm

Hence, the total square of the figure is 29 square cm

Part B

$\begin{gathered} \text{ To proof if the triangle is a right angled triangle} \\ \text{ We n}eed\text{ to appy Pythagora's theor}em \\ \text{Hypotenus}^2=perpendicular^2+base^2 \\ \text{Hypotenus = 4}cm \\ \text{Perpendicular =3cm} \\ \text{Base = 2cm} \\ 4^2=3^2+2^2 \\ 16\text{ = 9 + 4} \\ 16\text{ }\ne\text{ 13} \\ \text{ Since the hypotenus is not equal to the summation of the perpendicular and base} \\ \text{Hence, the triangle is a not right angled triangle} \end{gathered}$
