Answer:

l = 4a and b = 3a

Step-by-step explanation:

Given that,

The area of the rectangle, A = 12a²

Perimeter, P = 14a

The area and perimeter of a rectangle are given by :

A = lb

12a² = lb ....(1)

P = 2(l+b)

14a = 2(l+b) ....(2)

We need to solve equations (1) and (2). After solving we find that.

l = 4a and b = 3a

Hence, the dimensions of this rectangle are 4a and 3a.

Answer:

b = 40km is the answer.

Step-by-step explanation:

a = 9km

b = ?

c = 41km

By using the Pythagoras theorem,

a² + b² = c²

9² + b² = 41²

81 + b² = 1681

b² = 1681 - 81

b² = 1600

b = 40km

∴ b = 40km is the length of the missing leg.

Answer:

  30.85 in

Step-by-step explanation:

The circumference of a circle with a 6" radius is ...

  C = 2πr

  C = 2π(6 in)

Then the curved portion of a semicircle with that radius will have the length ...

  1/2C = 1/2(2π)(6 in) = 6π in . . . . curved length

The straight portion of the boundary of this figure is simply twice the radius, so is ...

  2×6 in = 12 in . . . . straight length

__

The perimeter is the sum of the curved and straight lengths:

  P = (6π +12) in ≈ 30.8496 in ≈ 30.85 in . . . . figure perimeter

Step-by-step explanation:

Answer:

x=30. y=60

Step-by-step explanation:

DG is a straight segment so it sums to 180 degrees. ECG is a right angle so 90 degrees. The rest is described as 2x and x. So 3x=90 degrees. x=30. Eh is also a straight segment. since we know x, we know that ECD is 60 degrees. So y+y=120 degrees. 2y=120. y=60.

Answer:

2

Step-by-step explanation:

The slope of a line is the change in the line. It is often referred to as the ([tex]\frac{rise}{run}[/tex]), the slope of the line can be found using the following formula,

[tex]\frac{y_2-y_1}{x_2-x_1}[/tex]

The graph of the given line gives one the points (7, 2), (9, 6). Substitute these points into the given formula and solve for the slope,

[tex]\frac{6 - 2}{9 - 7}[/tex]

Simplify,

[tex]=\frac{4}{2}[/tex]

[tex]=2[/tex]

12m³ is your answer

Answer:

Given:

length[l]=2m

breadth or width [b]=6m

height [h]=1/2 l=1/2×2=1m

it seems that it is a cuboid

we have

volume of cuboid =l×b×h=2×1×6=12m³

Answer:

Step-by-step explanation:

Use the cosine identity:

cos(x) = adj/hyp.

Here, adj = 2 and and x = 50° and hyp is unknown and what we are solving for.

adj/cos(x) = hyp, 2/cos(50) = hyp.

hyp = 3.11

Answer:

140 Calories and 4 grams of dietary fiber per 1/3-cup serving.  

Step-by-step explanation:

hi you can find this by first doubling the amounts for a 1/2 cup serving

so then it is equal to a full cup serving.

and then divide those by three,

that way it will be equal to 1/3 cup serving.

so

210*2= 420 (lol)

6*2= 12

now divide these numbers by 3

420/ 3 = 140

12/3= 4

so your answers are

140 Calories and 4 grams of dietary fiber per 1/3-cup serving.

I hope this helps! Good luck!

Answer:

5x, 4x and x.

Step-by-step explanation:

Like Terms. "Like terms" are terms whose variables (and their exponents such as the 2 in x2) are the same. In other words, terms that are "like" each other. So say we have 4,5,and 3x. 4 and 5 would be like terms because they are just whole numbers. If we added another number with a coefficient of x, it would be 3x's like term. It's not as simple though, because a number having letters doesn't just make it a like term. It has to be the same letter(s). 4x and 5y are not like terms but 4x and 5x would be. 4xy and 5yz are not like terms but 5yz and 6yz would be like terms.

Answer:

2's volume is 93 3/4 and 3's volume is 40

Step-by-step explanation:

Just use the formula to find volume, length x width x height. For 2, it would be 5x5x3 3/4 to give you a product of 93 3/4. For 3, it would be 3x2x6 2/3 which equals 40.
