Answer:

[tex]V=V_{1}+V_{2}=96+36=132\: cm^{3}[/tex]

Step-by-step explanation:

We can divide it into two parts:

First, we can fin the volume of the parallelepiped:

h1 = 16 cm

w1 = 2 cm

d1 = 3 cm

[tex]V_{1}=h_{1}*w_{1}*d_{1}=16*2*3=96\: cm^{3}[/tex]

Now, the volume of the second parallelepiped is:

h2 = (8-2) cm = 6 cm

w2 = 2 cm

d2 = 3 cm

[tex]V_{2}=h_{2}*w_{2}*d_{2}=6*2*3=36\: cm^{3}[/tex]

Finally, the total volume will be the addition of these two volumes.

[tex]V=V_{1}+V_{2}=96+36=132\: cm^{3}[/tex]

Answer:

  (d)  80 square units

Step-by-step explanation:

As with many composite area problems, this can be worked any of several ways. The attached shows trapezoid ABCE, from which triangle CDE can be removed to get the desired area.

The relevant formulas are ...

  A = (1/2)(b1 +b2)h . . . . . . area of a trapezoid

  A= (1/2)bh . . . . . . . . . . . . area of a triangle

__

Here, the trapezoid has bases 12 and 2, and height 12, so its area is ...

  A = (1/2)(12 +2)(12) = 84 . . . . square units

The triangle has a base of 4 and a height of 2, so its area is ...

  A = (1/2)(4)(2) = 4 . . . . square units

Then the area of the desired figure is ...

  84 - 4 = 80 . . . . square units

Answer:

yes, it is true because a supplimentary angle is 180 degrees and if their is an acute angle then it is less than 90 degrees which means you subtract that by 180 and you get a number over 90 and an obtuse angle is over 90 which means the other side of the acute angle is obtuse. And the suppliment to an acute angle is always over 90 degrees

Answer:

b.

Step-by-step explanation:

Answer:

The two trains are closing the initial distance between that of 280 miles by the sum of their two speeds. 80mph + 60mph = 140 mph. With the speed that the distance between the trains is closing, we can divide the starting distance to find out the number of hours until the trains pass. 280 miles / 140 mph = 2 hours. Since the trains left at 3:00 and will pass each other in 2 hours, they will pass each other at 5:00.

Answer:

5x

Step-by-step explanation:

. If the measures of angles A and B of triangle

ABC are each 2x + 5 and the measure of angle

C is 3x – 5, what is the measure of angle exterior

to angle A?​

Using the theorem

The sum of interior angle of a triangle is equal to its exterior

Given the interior angles 2x+5 and 3x-5

Sum= 2x+5+3x-5

Sum = 2x+3x+5-5

Sum = 5x+0

Sum = 5x

Hence the measure of the exterior angle is 5x

Answer:

answer is 1

Step-by-step explanation:

Let's solve your equation step-by-step.

2g−(−1)=3

Step 1: Simplify both sides of the equation.

2g+1=3

Step 2: Subtract 1 from both sides.

2g+1−1=3−1

2g=2

Step 3: Divide both sides by 2.

2g/2 = 2/2

g=1

Answer:

(3a + 2)(a + 3)

Step-by-step explanation:

Answer:

3x^2-6x+3=0

x^2-2x+1=0

x^2-x-x+1=0

x(x-1)-(x-1)=0

(x-1)(x-1)=0

x=1,1

so x has only one answer

so it intersects only one time

Answer:

Answer:

52.36%

Step-by-step explanation:

First, you need to find the radius of the circle. You can do this by using the Pythagorean theorem, which states a^2+b^2=c^2. In this case, a and b are equal to 1.2 and 1.6, and c is the radius of the circle. Plugging in we get 1.2^2+1.6^2=c^2 or 1.44+2.56=c^2 or 4=c^2. Finding the square root of both sides of the equation, we find that 2=c. Now that we have the radius, we can find the area of the circle. The area of a circle is expressed as πr^2, and plugging in 2 for r we get an area of 4π, or ~12.56637. Now all we do is divide 12,56637 by 24 and get what percentage of the area of the triangle the circle covers, which is roughly 0.5236, or 52.36%

Answer:

45/5 or 45

Step-by-step explanation:

5x9=45   45/9=9

so therefore there are 45 , 1/5 in 9

The number of times a fraction number 1/5 is present in the integer number 9 will be 45 times.

Algebra is the study of abstract symbols, while logic is the manipulation of all those ideas.

The acronym PEMDAS stands for Parenthesis, Exponent, Multiplication, Division, Addition, and Subtraction. This approach is used to answer the problem correctly and completely.

The number of times a fraction number 1/5 is present in the integer number 9 is calculated by the division of the number 9 by the fraction number 1/5. Then we have

⇒ 9 / (1/5)

⇒ 9 x 5

⇒ 45

The number of times a fraction number 1/5 is present in the integer number 9 will be 45 times.
