Answer:

the volume of the rectangular prism = 166.336 cubic cm

Hence, option C is correct. 

Step-by-step explanation:

We can determine the volume of the rectangular prism using the formula given below.

The volume of the rectangular prism = Base area x Height

Determining the Base area:

Given

Area of the Base area = l × w

                                     = 3.2 × 4.6

                                     = 14.72 cm²

Thus, the area of the Base area = 14.72 cm²

As the height h = 11.3 cm

Thus,

The volume of the rectangular prism = Base area x Height

                                                             = 14.72 x 11.3

                                                             = 166.336 cubic cm

Therefore, the volume of the rectangular prism = 166.336 cubic cm

Hence, option C is correct.                                                    

Answer:

25% fewer wheels than a car

Step-by-step explanation:

To calculate the percentage of fewer wheels that the autorickshaw has when compared to the car we have to first divide the number of wheels that the autorickshaw has by the number of wheels that the car has. Then we subtract that decimal value from 100 and then multiply that output by 100 to get the percentage value we are looking for. Like so...

333 / 444 = 0.75

100 - 0.75 = 0.25

0.25 * 100 = 25%

Finally, we can see that the percentage value is 25% fewer wheels than a car.

Answer:

Radius of the cylinder=Diameter/2=8/2=4 cm

Volume of the cylinder=π(radius)²(height)

22/7×4×4×15=754 cm³(approx)

Mass of the cylinder=Density×Volume

=1.95g/cm³×754cm³

=1470 grams

Mass of the cylinder is 1470 grams

Hence, the mass of the cylinder is 1469.52 grams

A solid geometric figure with straight parallel sides and a circular or oval cross section.

According to the figure given ,

[tex]r=[/tex] radius of cylinder = diameter of cylinder/2 = 8/2 = 4cm

[tex]h=[/tex] height of cylinder= 15 cm

therefore, by formula:

Volume of Cylinder= [tex]\pi r^2h[/tex]

[tex]=3.14*4*4*15[/tex]

= 753.6 cm^3   ...........................(1)

Now, by the formula:

Density = Mass/Volume

Given, Density of Cylinder = 1.95g/cm^3

and,  from (1)

Volume of Cylinder= 759.6 cm^3

therefore, Density = Mass of Cylinder/Volume of Cylinder

or, Mass Of Cylinder = Density*Volume

hence, Mass of Cylinder = [tex]1.95*753.6[/tex]

                                         =  1469.52 grams

Hence , Mass of Cylinder is 1469.52 grams.

Answer:

Solution,

<TWR = <PWQ = 128° [Vertically opposite angles]

<TWS = 128°-31° = 97° = [tex]\frac{97\pi ^{c}}{180}[/tex] = ∝

Arc TS (l) = ?

Radius (r) = 4.5mm

Now,

[tex]\alpha = \frac{l}{r} \\or, \frac{97\pi ^{c}}{180} = \frac{l}{4.5} \\or, l = \frac{(97\pi)(4.5) }{180} = \frac{436.5\pi }{180}[/tex]≈ 7.61mm

The required measure of the arc TS is given as 7.61 mm.

Orientation of the one line with respect to the horizontal or other respective line is known as a measure of orientation and this measure is known as the angle.

Here,
In the diagram,
∠TWR = ∠PWQ
∠TS + 31 = 128
∠TS = 97°

Now,
Arc = angle × radius
Arc = 97 × π /180 × 4.5
Arc =  7.61 mm

Thus, the required measure of the arc TS is given as 7.61 mm.

Answer:

5cm

Step-by-step explanation:

Assuming the two horizontal legs are parallel, the smaller triangle is similar to the larger one, so that corresponding sides occur in a fixed ratio. In particular, you have

(6 cm) / (4 cm) = (6 cm + b) / (7 cm)

Solve for b :

(6 cm) • (7 cm) / (4 cm) = 6 cm + b

b = (6 cm) • (7 cm) / (4 cm) - 6 cm

b = 9/2 cm = 4.5 cm

Answer:

The best way to measure an angle is to use a protractor. To do this, you'll start by lining up one ray along the 0-degree line on the protractor. Then, line up the vertex with the midpoint of the protractor. Follow the second ray to determine the angle's measurement to the nearest degree.

Step-by-step explanation:

Answer:

21) Angle A = 44 degrees

22) Angle A = 23 degrees

Step-by-step explanation:

The angles inside of every triangle always add up to 180 degrees, you can use this trigonometric identity to solve for x values:

Problem 21)

X + 59 + X + 51 + 84 = 180

2x + 194 = 180

2x = -14

x = -7

now solve for angle A:

Angle A = x + 51 = -7 + 51 = 44 degrees

Problem 22)

The square symbol inside a triangle denotes a 90 degree angle. Setting the angles equal to 180 degrees, you can find angle A again.

90 + x + 37 + x + 67 = 180

2x + 194 = 180

2x = -14

x = -7

now solve for angle A:

Angle A = -14 + 37 = 23 degrees

Step-by-step explanation:

[tex]26 = x + y \\ where \: x \: is \: the \: pack \: of \: pens \: and \: y \: is \: for \: the \: binders \\ but \: x = one \: pack \: of \: pens \\ = 1 \times 4.15 \\ y = 5 \times number \: of \: binders \\ substituting \\ 26 = 1(4.15) + 5x \\ 26 - 4.15 = 5x \\ 21.85 = 5x \\ x = 4.37[/tex]

Jasmine has only $26 to buy her materials, and we found that the highest number of binders she could buy is at 4.37.

The variable is the second x which is the number of binders since she could change the amount of binder she wants to buy. Comparing to the one pack of pens, Jasmine has already decided that she will only buy one not two, not three, etc. Therefore, the pack of pens is not a variable as she cannot change the amount of pack of pens she can buy.

Answer:

she could buy 4 binders and 1 pack of pens and she have 85cents left
