What is the length of a car if the length on the scale model car is 17cm and the scale is 2cm : 50cm?

Answer:

A 3 cm

Step-by-step explanation:

Volume is lxwxh, 6x9= 54, and 54x3=162

Answer: 3

Step-by-step explanation:

The equation for volume of a rectangular prism is lwh. We have the lh and 6 times 9 is 54. Now we just divide 162 and 54 and that's the width which is 3. And to double check 3 times 9 times 6 is 162 :)

Answer:

8: 73.2 cm

10: 738 mm

Step-by-step explanation:

8: A= 12.2 (4.5 + 7.5) / 2 --> 146.2 / 2 = 73.2 cm

10: A= 36 (22 + 19) / 2 --> 1,476 / 2 = 738 mm

Answer:

8: 73.2

10: 738

Step-by-step explanation:

Area of a trapezoid = [tex]A=\frac{a+b}{2} h[/tex]

where a and b = base lengths and h = height

For #8

These are the given dimensions

Base 1 = 4.5

Base 2 = 7.5

Height = 12.2

All we have to do is plug in the values into the formula

So....

[tex]A=\frac{4.5+7.5}{2} 12.2\\4.5+7.5=12\\\frac{12}{2} =6\\6*12.2=73.2[/tex]

Hence the answer is 73.2cm²

For #10

Once again all we have to do is plug in the values into the formula

[tex]A=\frac{22+19}{2} 36\\22+19=41\\\frac{41}{2} =20.5\\20.5*36=738[/tex]

Hence the answer is 738

Answer:

7/2 feet

Step-by-step explanation:

Volume of Right Rectangular Prism: V = w * h * l

You are given the volume, and the base (which would include l and w)- and are told to find h.

70 7/8 cubic feet = 4 1/2 feet * h * 4 1/2 feet (simplify the right side)

70 7/8 cubic feet = 81/4 feet squared * h (divide both sides by 81/4)

7/2 feet = h

The height will be 7/2

Answer:

Jasraj walked 4 kilometers all together

Step-by-step explanation:

First, add.

1,500 + 500 = 2,000

Then, multiply by 2.

2,000 × 2 = 4,000

Now, we have to convert to kilometers.

1 kilometer = 1000 meters

4,000 ÷ 1,000 = 4

So, Jasraj walked 4 kilometers!

Have a wondeful day! :)

Answer:

5/8

Step-by-step explanation:

1/4 is equal to 2/8.2/8 +3/8 is 5/8 add them together you get 8/8.

Answer:

8.88

Step-by-step explanation:

I believe it is 8.88 becuase this question is asking to find 90% pf that number.  

What do you need to do?

you have to make a proportion.

8/x 90/ 100

You would now cross multiply. 90* x = 90x 8*100= 800

the equation you would need is 90x = 800. divide them and you get 8.88.

ROUNDED: you get 9.

I believe this is correct sorry if it was incorrect.

Step-by-step explanation:

Step-by-step explanation:

I don’t really wanna help, so thanks for the points! Don’t scroll down! I’m warning you!!!

Figure 1 and Figure 4 have the same areas because the area of a parallelogram is just length times width.

Figure 1: 15×4=60 cm

Figure 2: 18×3=54 cm

Figure 3: 11×6=66 cm

Figure 4: 12×5=60 cm

As you can see, figure 1 and figure 4 have the same areas. So, C is the correct answer.

Answer:

5200

Step-by-step explanation:

30% of 4000 is 1200

4000+1200

Answer:

5200  

Step-by-step explanation:  

200×20=4000  

30% of 4000 is 1200

4000+1200=5200

Answer:

Step-by-step explanation:

Circumstance of a curcle C=2*pi*r

So if you want to find r from this equation you come up with r=C/2*pi. That's exactly what they give you in the problem.

Now you know that C= 26.69 so replacing what we know in the formula r=C/2*pi you get

r=26.69/2*3.14 =4.25

So looking at the figure you they said r=4.25

That means that the figure is has to be a circle.

Hope that makes sense.

Answer:

A = (1/2)Pa = Pa/2

You can multiply both sides by 2 to eliminate the fraction on the right side:

2A = 2(Pa/2) = Pa

Then divide both sides by a (or multiply both sides by 1/a) to leave P alone on the right side:

(2A)(1/a) = 2A/a = (Pa)(1/a) = P

Rewriting:

P = 2A/a

You could also have divided by a first then multiplied by 2; which you should do first does not matter in this example.

Step-by-step explanation:

The greatest possible length of each piece is 2 cm.

The highest common factor is defined as the set of numbers with the highest common multiple. The highest positive integer with more than one factor in the set is HCF.

Three ropes of length 2 m 84 cm, 4 m 26 cm, and 7 m 10 cm are to be cut into small pieces of equal length.

We have been given the lengths of the ropes as

2 m 84 cm = 284cm

4 m 26 cm = 426cm

7 m 10 cm= 710 cm

We have to determine the greatest possible length of each equal part So that there is no wastage

So the greatest possible length of each piece will be the HCF of the length of the ropes.

⇒ 284 = 2× 142

⇒ 426 = 2 × 213

⇒ 710 = 2 × 355

Hence, the HCF of the 284, 426, and 710 is 2.

Therefore, the greatest possible length of each piece is 2 cm.
