What is multiplication?

In mathematics, multiplication is a method of finding the product of two or more numbers. It is one of the basic arithmetic operations, that we use in everyday life.

Here, we have,

a model car has a scale of 3 cm : 2 m.

The length of the actual hood of the car is 1 m.

Now,

Set up a proportion:

3cm/2m = x/1m

Cross-multiply:

2x=3

Divide by 2:

x=1.5 cm

Hence, 1.5 cm is the length of the model.

Answers

SA=2(LW+LH+WH)
L=8
W=6
H=4
SA=2(8*6+8*4+6*4)
SA=2(48+32+24)
SA=2(104)
SA=208 yd^2

answer is D

How to find the surface area of Rectangular Prisms:

Find the area of two sides (Length*Height)*2 sides;
Find the area of adjacent sides (Width*Height)*2 sides;
Find the area of ends (Length*Width)*2 ends;
Add the three areas together to find the surface areais .

The surface area of a rectangular prism is 8*6 + 6*4 + 8*4 = 48 + 24 + 32 = 72 + 32 = 104 yd2.

The diagonals of a parallelogram QRST, TR And QS, Intersect at point U, if RS = 10 , ST=12,And RU=9.5 , Find The Perimeter Of The parallelogram QRST.A. 39
B. 44
C. 88
D.100

Answers

Answer:

(B)44

Step-by-step explanation:

It is given that The diagonals of a parallelogram QRST, TR And QS, Intersect at point U, if RS = 10 , ST=12,And RU=9.5.

Now, Since, RS =10, then RS=QT=10 (Opposite sides of parallelogram are equal).

And, ST=12, then ST=QR=12 (Opposite sides of parallelogram are equal)

Thus, The perimeter of the parallelogram QRST is given as:

Perimeter=Sum of all the sides

Perimeter=QR+RS+ST+TQ

Perimeter=12+10+12+10

Perimeter=44

Therefore, the perimeter of the given parallelogram QRST is 44 units.

Hence, option B is correct.

The answer is B. 44
