Answer:

240  x 15 = 3600

Step-by-step explanation:

Find : 240 x 15

The Distributive Property states that:

A(B +C) = AB + AC

(a) 240 x 5 = 1200

(b) 240  x  ______  = 2400

or, ______  = 2400 / 240 = 10

⇒ 240  x<u>  10 </u>= 2400

c) 12,00  + _____  = _____

⇒  1,200  + <u> 2,400</u>  = <u>3,600</u>

<u />

Now, 240  x 15  = 240 (10 + 5)

                          =  240(10)  + <u>240 (5</u>)          [Using the Distributive Property]

                          =   2400 + <u>1200 </u>   ( from (a), (b) )

                          = 3600   (using (c))

Hence, 240  x 15 = 3600

Guys can u help me asap ?? i need explaination aloong the answer
Alisiya [41]

Answer:

5225 x 5/100 = 261.25

5225 - 261.25 = 4963.75

Step-by-step explanation:

We know that % means a 100 so if they say they allowed a 5% discount then that would be 5/100.

You will take the fraction and multiple it with the original price. It will then give you the discount price, you will then need to subtract the discounted amount from the original sale price which is 5225. Then you will get your final answer.

On a mountain, the temperature decreases by 18°F every 5000 feet. What integer represents the change in temperature at 20,000 ft
attashe74 [19]
<span>To find this answer, use multiples. For every 5000 feet ascended, deduct 18 degrees. For 20,000 feet, which is (4 * 5000), use (4 * -18). In this case, the answer is -72 degrees F, so the integer described would be -72.</span>

plsss helppp need it fastt .. what is the volume of this figure answer your answer in the box . 4ft 3ft 8ft 2ft 6ft
PolarNik [594]

Answer:

e

Step-by-step explanation:

The cube on the top, the one with the width of 4 is Cube 1.

The other one is Cube 2.

The length of the cube is 4, the width 2, and the height 5.

We know the length is 4 because we can look at the side, where both measurements 6 ft and 3 ft can be found.

We know that the height is 5 because for Cube 2, the height is 3. The total height is 8, so we subtract 3 from 8. We get our difference of 5.

V = l x w x h

V = (4)(2)(5)

V = (8)(5)

V = 40.

Cube 2 has a length is 6, the width 2, and the height 3.

V = l x w x h

V = (6)(2)(3)

V = (12)(3)

V = 36

We add the volumes of both cubes.

40 + 36 = 76

probs not right but hope it helped :)

How do u do b??????????
horrorfan [7]

the assumption being that the first machine is the one on the left-hand-side and the second is the one on the right-hand-side.

the input goes to the 1st machine and the output of that goes to the 2nd machine.

a)

if she uses and input of 6 on the 2nd one, the result will be 6² - 6  = 30, if we feed that to the 1st one the result will be √( 30 - 5) = √25 = 5, so, simply having the machines swap places will work to get a final output of 5.

b)

clearly we can never get an output  of -5 from a square root, however we can from the quadratic one, the 2nd machine/equation.

let's check something, we need a -5 on the 2nd, so

\bf \underset{final~out put}{\stackrel{y}{-5}}=x^2-6\implies 1=x^2\implies \sqrt{1}=x\implies 1=x

so if we use a "1" as the output on the first machine, we should be able to find out what input we need, let's do that.

\bf \underset{first~out put}{\stackrel{y}{1}}=\sqrt{x-5}\implies 1^2=x-5\implies 1=x-5\implies 6=x

so if we use an input of 6 on the first machine, we should be able to get a -5 as final output from the 2nd machine.

\bf \stackrel{first~machine}{y=\sqrt{\boxed{6}-5}}\implies y=\sqrt{1}\implies y=1 \\\\\\ \stackrel{second~machine}{y = \boxed{1}^2-6}\implies y = 1-6\implies y = -5
