Answer:

The length of the rectangle is equal to 6 cm and the width is equal to 4 cm.

Step-by-step explanation:

Given is : The length of the lab is 32 feet and the width of the lab is 48 feet and each 16 feet of the lab equals 2 centimeters on a scale drawing.

So, We will divide the actual length with 16 and multiply by 2 as 16 feet is equal to 2 cm.

So, length will be =  = 6 cm

Width will be =  = 4 cm

Therefore, the length of the rectangle is equal to 6 cm and the width is equal to 4 cm

What is the value of x
Mama L [17]

Answer:

X equals 45

Step-by-step explanation:

The angle all together is 180 degrees so if you do 180 minus 45 you get 135. Now since x is being multiplied by 3 you divide 135 by 3. This is 45. So x is equal to 35. hopefully that made sense. :)

Christine went shopping and bought each of her eighteight nephews a​ gift, either a video costing​ $14.95 or a CD costing​ $16.8
pogonyaev
So I think you should set up an equation like this: 14.95x+16.88y=131.18 , x+y=8

so x=8-y, plug this into the original equation:
14.95(8-y)+16.88y=131.18
Evaluate: 119.60-14.95y+16.88y=131.18
Combine like terms: 119.60+1.93y=131.18
Subtract 119.60 from both sides. You get: 1.93y=11.58
Divide both sides by 1.93. You get y=6

Plug into second equation: x+y=8 ---> x+6=8 and solve for x. x=2

Christine bought 2 video games and 6 CDs. 14.95(2)+16.88(6)=131.18

During the first few years of a tree's life, its growth rate is linear. For example, an oak tree grows at a rate of 1.5 feet per
Pavlova-9 [17]

Answer:

Mostafa's maple tree grows at a slower yearly rate than an oak tree.

Step-by-step explanation:

Given that:

An oak tree grows at a rate of 1.5 feet per year for twelve years;

After 12 year; the oak tree will be = 12 × 1.5 = 18 feet per year.

Now; we are being told that Mostafa plants a maple tree at his backyard and measures its height at 4 feet.

i.e x years  = 4 ft

two years later ; it height is now 6.5 ft

thus;

x year = 4 ft

x + 2 = 6.5 ft

6.5 * x = (x+2)4\\  \\ 6.5 x = 4x + 8\\ \\ 6.5x-4x = 8\\ \\ 2.5x = 8\\ \\ x = \dfrac{8}{2.5}\\ \\ x = 3.2

Thus ; Mostafa first measured the height of the tree when it is 4 ft at the age year of  3.2

So;

if 3.2 year = 4 ft

1 year = x

x  = \dfrac{4 *1 }{3.2}

x  = 1.25 ft

So if an oak tree grows at the rate of 1.5 ft in a year.

Then, Mostafa's maple tree grows at the rate of 1.25 ft in a year.

From the given information in the diagram attached below; we can infer that :

Mostafa's maple tree grows at a slower yearly rate than an oak tree.
