Are the fractions 1.3 over 5.2 equal to 12 over 48

Answers

Answer 1

Answer: the answer is yes.
you can find each fraction and see if they are equal or not so in this question you can say:
1.3/5.2 = 0.25 and 12/48 = 0.25 so both of them are equals to 0.25 :)))
I hope this is helpful
have a nice day

Answer 2

Answer: $(1.3)/(5.2)= (1.3*10)/(5.2*10)=(13)/(52)=(13\cdo:13)/(52:13)=(1)/(4)=(1*12)/(4*12)=(12)/(48)$

So, yes. The fractions are equal.

What scale factor was used in the dilation

Answers

4 divide by 10 is 0.4

The answer is 0.4

Divide the image length M'P' over its corresponding preimage length MP

(length of M'P')/(length of MP) = 4/10 = 2/5 = 0.4

Answer: 0.4 which is choice C

The fact that the scale factor is less than 1 and its positive means that the image is smaller than the preimage (aka the figure shrinks). The result is positive because we don't have any reflections going on.

A square painting has a diagonal of 44 in. Lorraine wants to frame the picture. How many inches of frame will she need? Round to the nearest inch.

Answers

The square has a diagonal of 44 inches.
In order to get the side, we need to use the pythagorean equation.

Diagonal (d) ^ 2 = side^2 + side ^ 2
Diagonal (d) ^ 2 = 2side (s)^2

d^2 = 2s^2
44^2 = 2s^2
1936 = 2s^2
2s^2 = 1936
s^2 = 968
s = 31.11 inches

The length of the side is approximately 31 inches.
Perimeter = 4*s
Perimeter = 4 * 31
Perimeter = 124 inches

So she need a total of 124 inches to frame the square.

I am sure the anwser is 124in

I hope this helps let me know! ;)

Simplify; 5a+3b-7a+4b

Answers

Answer:

$- 2 a + 7 b$

Step-by-step explanation:

We are given the following expression and we are to simplify it:

$5 a + 3 b - 7 a + 4 b$

Re-arranging this expression by writing the like terms together to get:

$5 a - 7 a + 3 b + 4 b$

Now simplifying it by adding and subtracting the terms to get:

$- 2 a + 7 b$

Combine like terms:

5a-7a=-2a

3b+4b=7b

-2a+7b

Hope this helps!!

An object has a velocity of 8 m/s and a kinetic energy of 480 J. What is the mass of the object? Formula=1/2mv^2 a(7.5 b(15 kg c(60 kg d(120 kgnevermind i found the answer its (15 kg) because to solve for m its m= K2/v squared

Answers

The Kinetic Energy (K.E) of an object can be calculated as:

$K.E= (1)/(2)mv^(2)$

We are given:
K.E = 480 K
Velocity of the object = v = 8 m/s

Using the values, we get:

$480= (1)/(2)m(8)^(2) \n \n 480= (1)/(2)*64m \n \n 480=32m \n \n m=15$

Thus, the mass of the object will be 15 kg.

So the correct answer is option b

Hello!

An object has a velocity of 8 m/s and a kinetic energy of 480 J. What is the mass of the object ?

We have the following data:

KE (Kinetic Energy) = 480 J

m (mass) = ? (in Kg)

v (speed) = 8 m/s

Formula to calculate kinetic energy:

$\boxed{KE = (1)/(2)*m*v^2}$
