Step-by-step explanation:

A couch was originally priced $500 dollars and on sale for 70% off what is the price for after the discount

Answers

Answer: the answer would be $150

Step-by-step explanation:

Answer:$150.00

Step-by-step explanation:

If you think about a item going down by 70%, it means that you are paying only 30% of the total price.

100%-70%=30%

So 30% of $500 is what you are paying.

30%=30/100=0.3

So you multiply 0.3x500

Which is equal to 150

The length of the rectangular field is two times its breadth. If the perimeter of the field is 300m, find the length and breadth.

Answers

Answer:

Youu can call the breadth x and then, as the length is two times the breadth, it would be 2x.

So now when we call x to the breadth and 2x to the length we can do an equation, as we know the sum of the four sides is 300 meters, so

2x + 2x + x + x = 300

6x = 300

x = 300/6 = 50

We know that the breadth is 50m, and, the length, which is twice the breadth, would be 100m in this exercise.

SO in this case, the breadth is 50 meters and the length is 100 meters..

I need 110g of flour to make something. A 10kg (22lb) bag of four is $12. How much does that 110g cost?

Answers

Answer:

Cost of 110 g bag = $ 0.132

Step-by-step explanation:

As we know ,

1 kg = 1000 g

⇒1000 g = 1 kg

⇒1 g = [tex]\frac{1}{1000} = 0.001[/tex] kg

⇒110 g = 110 (0.001) kg = 0.11 kg

⇒110 g = 0.11 kg

Now,

Cost of 10 kg bag = $12

⇒Cost of 1 kg bag = [tex]\frac{12}{10} = 1.2[/tex]

⇒Cost of 1 kg bag = $ 1.2

⇒Cost of 0.11 kg bag = $ (0.11)(1.2) = $ 0.132

∴ we get

Cost of 110 g bag = $ 0.132

Answers

Answer:

"?" = 3

Step-by-step explanation:

The answer can be gotten by subtracting 4 from 7. The 4 is the exponent in (4a^4b), and the 7 is the exponent in 16a^7b. So:

7 - 4 = 3

Therefore, the "?" = 3

Hope this helps :)

Answer:

?=3

Step-by-step explanation:

Okay so with exponents, when multiplying exponents with the same base, you add them.

In your case, we have a^? * a^4=a^7 (this is the only part you need to solve)

so ?+4=7

?=7-4=3

The ratio of boys to girls in a group is 3:1. If there are 52 more boys than girls, work out how
many people there are in total.

Answers

Answer:

104

Step-by-step explanation:

The ratio of boys : girls = 3 : 1 = 3x : x ( x is a multiplier )

There are 52 more boys than girls , so

3x = x + 52 ( subtract x from both sides )

2x = 52 ( divide both sides by 2 )

x = 26, then

3x = 3 × 26 = 78 ← number of boys

Total number = 78 + 26 = 104

Assume that x = x(t) and y = y(t). Let y = x^2 + 6 and

Find dy/dt when x = 1​

Answers

Answer:

[tex]\frac{dy}{dt}[/tex] = 8

Step-by-step explanation:

Given:

x = x(t) and y = y(t)

Let y = x² + 6

By differentiating the given equation with respect to t,

[tex]\frac{dy}{dt}=\frac{d}{dt}(x^{2}+6)[/tex]

[tex]\frac{dy}{dt}=\frac{d}{dt}(x^{2})+\frac{d}{dt}(6)[/tex]

Since, [tex]\frac{dx}{dt}=4[/tex] when x = 1

[tex]\frac{dy}{dt}=2x\frac{dx}{dt}+\frac{d}{dt}(6)[/tex]

[tex]\frac{dy}{dt}=2(1)(4)+0[/tex] [By substituting the values of [tex]\frac{dx}{dt}[/tex] and x = 1]

[tex]\frac{dy}{dt}[/tex] = 8
