The lenght of a triangle is 5 centimters greater than its width . the perimeter is 58 centimeters what are demetions of the rect

steposvetlana [31]

Let the width be x.

Length = 5 + x

Perimeter = 58

2(l + w) = 58

2(5 + x + x) = 58

2(5 + 2x) = 58

10 + 4x = 58

4x = 48

x = 12

Hence, the length is 17 cm and the width is 12 cm.

Determine whether quantities vary directly or inversely and find the constant of variation. If 5 bushels of wheat weigh 136 kg,

pentagon [3]

Let the bushels of wheat is b and weight of the wheat is w.

We can say that more the bushels of wheat more will be the weight of the wheat.

Hence, the quantities vary directly.

Therefore, we have

$b=kw$ , where k is the constant of variation.

Now, we have been given that 5 bushels of wheat weigh 136 kg. Thus, we have

$5=136k\\
\\
k=\frac{5}{136}$

Thus, the constant of variation is $\frac{5}{136}$

Now, we have been given 3.5 bushels of wheat. Hence, we have

$3.5=\frac{5}{136} w\\
\\
w=\frac{136\times 3.5}{5} \\
\\
w=95.2$

Therefore, 3.5 bushels of wheat weigh 95.2 kg

Assume that y varies inversely as x. If, y, is 2.4 when x = 5, which is an equation that relates x and y?

Firlakuza [10]

K=y•x
Inverse means 1/variable
y=k•1/x
y=k/x
k=y•x

x=5
y=2.4
k=2.4 • 5
k=12

Answer is:

y=12/x

Good luck.

The vertices of a rectangle are (1, -3), (4,0), (0,4) and (-3,1). What is the area of the rectangle?

motikmotik

Answer:

Step-by-step explanation:

You can use a graphing calculator like desmos or draw your own graph to figure this out. Start by graphing each of those points. Then count the width and height. Multiply them to get the area. The width and height of the rectangle were 6 and 8, so the area is 48
