Answer:

9

Step-by-step explanation:

Using PEMDAS, we do what inside the parentheses first.

Multiplication before subtraction:

9-6 = 3.

Finally, 3^2 = 9

Answer:

2 pt + 1c

Step-by-step explanation:

There are 2 cups in a pint. So, 2c = p, dividing 2 from both sides, we get

c = (1/2)p

Replace c with 1/2 p in the equation

5 pt - (2pt + (1/2)p)

= 5pt - 2pi - (1/2)p

= 3pt  - (1/2)p

= 2pt  + (1/2)p

Replace back (1/2)p for c

2pt  + (1/2)p =

2 pt + 1c

Answer:

[tex]x<12[/tex] or [tex]x > 27[/tex]

Step-by-step explanation:

Given

[tex]Lower\ Bound = 20[/tex]

[tex]Upper\ Bound = 35[/tex]

[tex]Height = 8[/tex]

Required

Represent as a compound inequality

Let the pole height be x:

So, the combine height of the pole and the sign is [tex]x + 8[/tex]

The height must be less than 20ft.

So, we have:

[tex]x + 8 < 20[/tex]

Subtract 8 from both sides

[tex]x + 8 - 8 < 20 - 8[/tex]

[tex]x < 20 - 8[/tex]

[tex]x<12[/tex]

or The height must be less than35ft

So, we have:

[tex]x + 8 > 35[/tex]

Subtract 8 from both sides

[tex]x + 8 - 8 > 35 - 8[/tex]

[tex]x > 35 - 8[/tex]

[tex]x > 27[/tex]

So, the compound inequality is:

[tex]x<12[/tex] or [tex]x > 27[/tex]

Answer:

103 ft.

Answer:

For figure 1:

Area of rectangle = 7x + 21

For figure 2:

Area of rectangle = [tex]\mathbf{p^2-9p }[/tex]

Step-by-step explanation:

We need to find area of rectangle

The formula used is: [tex]Area\:of\:rectangle=Length\times Width[/tex]

For figure 1:

Length = 7

Width = x+3

Putting values in formula and finding area of rectangle

[tex]Area\:of\:rectangle=Length\times Width\\Area\:of\:rectangle=7\times (x+3)\\Now,\: multiply\:7\:with\:terms\;inside\:the\:bracket\\Area\:of\:rectangle=7(x)+7(3)\\Area\:of\:rectangle=7x+21\\[/tex]

So, area of rectangle = 7x + 21

For figure 2:

Length = p

Width = p-9

Putting values in formula and finding area of rectangle

[tex]Area\:of\:rectangle=Length\times Width\\Area\:of\:rectangle=p\times (p-9)\\Now,\: multiply\:p\:with\:terms\;inside\:the\:bracket\\Area\:of\:rectangle=p(p)-p(9)\\Area\:of\:rectangle=p^2-9p\\[/tex]

So, area of rectangle = [tex]\mathbf{p^2-9p }[/tex]

Answer:

[tex]\huge\boxed{y=-\frac{1}{7}x+ 10}[/tex]

Step-by-step explanation:

In order to find the equation of this line, we need to note two things.

So first, let's find the opposite reciprocal of 7 which will be the slope to this equation.

So the slope of this line will be [tex]-\frac{1}{7}[/tex]. The y-intercept will change, and we can substitute what we know into the equation [tex]y=mx+b[/tex].

[tex]y = -\frac{1}{7}x+b[/tex]

Now, we can substitute a point on the graph (14, 8) into this equation to find b.

Now that we know the y-intercept, we can finish off our equation by plugging that in.

[tex]y = -\frac{1}{7}x + 10[/tex]

Hope this helped!

Answer:

1.2 years

Step-by-step explanation:

The value of a certain account after t years is given by :

B = 600 × 1.2t dollars ....(1)

We need to find how long will it take for the value of the account to increase to $900 i.e. we need to find the value of t.

Put B = $900 in equation (1).

[tex]900=600\times 1.2t\\\\t=\dfrac{900}{600\times 1.2}\\\\t=1.2\ \text{years }[/tex]

So, it will take 1.2 years of the account to increase to $900.

Answer:

420 students

Step-by-step explanation:

965-541=424

round to the nearest ten and you get 420

i hope this helped, please mark this as brainliest! thanks

Answer:

The answer is 420

Step-by-step explanation:

You first do the equation 965 - 541. The answer to that is 424, but when you round it to the nearest ten, the answer would be 420.

Did the diagnosic

Answer:

x = 4.99°

Step-by-step explanation:

Reference angle = x

Opposite side to x = 20 cm

Hypotenuse = 230 cm

Applying trigonometric ratio formula, we would have the following equation:

[tex] sin(x) = \frac{Opp}{Hyp} [/tex]

Plug in the values

[tex] sin(x) = \frac{20}{230} [/tex]

[tex] x = sin^{-1}(\frac{20}{230}) [/tex]

x = 4.99° (approximated to nearest hundredth)

The answer is C hope it helps
