Answer:

5 cameras they sell

Step-by-step explanation:

P = 3x² – 3x + 10       p = 70

3x² – 3x + 10 = 70

3x² – 3x - 60 = 0

x² - x -20 = 0

(x + 4) (x - 5) = 0

x can't be negative, x = 5

The no of cameras sold if A camera shop's daily profit is given by P = 3x² – 3x + 10, where x is the total number of cameras sold in the day. If they only had a profit of $70 today is 5.

A mathematical statement that has an "equal to" symbol between two expressions with equal values is called an equation. As in, 3x + 5 Equals 15, instances. Equations come in a variety of forms, including linear, quadratic, cubic, and others.

Given:

The equation, P = 3x² - 3x + 10,

If P = 70 then,

70 =  3x² - 3x + 10

x = 5 and -4 but the number of cameras can not be negative

Therefore, The no of cameras sold if A camera shop's daily profit is given by P = 3x2 – 3x + 10, where x is the total number of cameras sold in the day. If they only had a profit of $70 today is 5.

Answer:

A

Step-by-step explanation:

3x+h=180

h=180-3x

x+15+x+15+180-3x=180

-x+210=180

-x= -30

x=30

Now that we know that x=30 we can easily figure out the values of the other angles

Answer:

Initial amount = 8

Decay rate = 15%

Step-by-step explanation:

Given the exponential function :

y = 8(1 – 0.15)

The general form of an exponential Decay function is :

A = P(1 - r)^t

Where

A = final amout ; P = initial amount ; r = days cay rate ; t = time

Hence, comparing with the equation given :

P = 8 = initial amount

r = 0.15 = 0.15 * 100% = 15% = Decay rate

Hi there!

Fractions can be equivalent to a lot other fractions...

Explanation:

43/12x2 would be 86/24 so that would be equivalent.

Let do another one..

43/12 when doing this, you can decide to divide or not but this is in the simplest form already so we can just multiply 43 and 12 with anything we want so let do... 5.

So 43 multiply by 5 would be..215 and 12x5 would be 60. So another equivalent fractions that’s the same as 43/12 or we can say 86/24 is 215/60.

I also added how I got the equivalent fractions just in case you don’t understand still...

Answer:

[tex]f^-^1(x) = x+11[/tex]

Step-by-step explanation:

- Write as an equation.

y = x - 11

- Interchange the variables.

x = y - 11

- Solve for  y

y = x + 11

- Replace the  y  with [tex]f^-^1(x)[/tex] to show the final answer.

[tex]f^-^1(x) = x+11[/tex]

Answer:

$18.15

Step-by-step explanation:

Yuki is paying tax of 4.6% + 3.65% = 8.25%

Converting to decimal form, that is 8.25/100 = 0.0825

Multiply that by the original sale price. 0.0825 x $220 = $18.15 exactly for tax.

The question asks for the tax, NOT for the total she will pay. Please don't get them mixed up.

Answer:

A reflection of a geometric shape is the mirror image of the shape.

Hope this helps, thank you !!

With the given scale factor, perimeter of polygon's image is 9 units. Therefore, option A is the correct answer.

Given that, the perimeter of a polygon = 12 units and the scale factor = 3/4.

A scale factor is defined as the ratio between the scale of a given original object and a new object, which is its representation but of a different size (bigger or smaller).

The basic formula to find the scale factor of a figure is expressed as,

Scale factor = Dimensions of the new shape ÷ Dimensions of the original shape.

So, 3/4 = Dimensions of the new shape/12

= 3/4 × 12

= 3 × 3

= 9 units

With the given scale factor, perimeter of polygon's image is 9 units. Therefore, option A is the correct answer.

Answer: 15

Step-by-step explanation:

From the question, we are informed that Wezi has sixty-three $5-bills. The total amount that he has will be:

= 63 × $5

= $315

We are further told that he takes the $5-bills to the bank to exchange them for $20-bills. Based on this, the number of $20-bills that Wezi get will be:

= $315 / $20

= 15 3/4

Therefore, he will get 15 $20 bills

Step-by-step explanation:

For a

Let the another angle be x then

x + 51° = 90° {being complementary angles }

x = 90° - 51°

x = 39°

For b

Let the another angle be x then

x + 113° = 180° {being supplementary angles }

x = 180° - 113°

x = 67°
