Answer:

a) 12 ft for the length and the width

b) 7 ft as the length for each side

Step-by-step explanation:

a) Area = length x width

Since the shape is a square, that means that the length and the width have to be the same.

Because of this you have to square root 144 and you get 12 since 12x12 = 144.

b) For perimeter, this is the sum of all sides. Since a square has 4 sides and all these sides must be the same length since the shape is a square, then you have to do 28 ÷ 4 and you get 7 as your answer

Answer:

n = -1.825

Step-by-step explanation:

8n + 16.2 = 1.6 (Given)

8n = -14.6 (Subtract 16.2 on both sides)

n = -1.825 (Divide 8 on both sides)

Answer:

6.7

Step-by-step explanation:

Theres a formula to figure this out. If you know two sides of a right angle triangle you can find the third.

Use the formula a²=b²+c², where a is the side opposite the right angle and b and c are the other sides.

a²=b²+c²

7²=2²+c²

49=4+c²

49-4=c²

c=√45 or 6.7082039325

Answer:

$25,226

Step-by-step explanation:

We know that one billion is equal to 1,000 millions

So, we first multiply 80.8 by 1,000 so we can use millions as our unit.

Which gives you $80,800

So, East Dakota spent $80,800 million in 2016 for the 3.203 million people. Right now, we just ignore the "million" part and divide 80,800 by 3.203 which is around 25,226.35029659694

Now we just round it to the nearest dollar and since the tens place is only at 3, we round down.

Hence, our answer is $25,226

Answer:

tax = $30.00 * 8% tax = $30.00 * 0.08 tax = $2.40

Step-by-step explanation:

Let the normal speed = x mph

The way to his grandmothers they drove 2x miles

Return trip was 2.25(x-5)

Set those equal and solve for x:

2x = 2.25(x-5)

Simplify:

2x = 2.25x -11.25

Subtract 2.25x from both sides:

-0.25x = -11.25

Divide both sides by-0.25:

X = 45

The usual speed is 45 mph.

So now 2 hours at 45 mph = 90 miles to his grandmothers house

Answer:

90 miles

Step-by-step explanation:

We did this in class when we were going over the hw and decided to help. Sorry if I'm too late.

Given :

A function, f(x) = -6 + 12

To Find :

The value of f(x) when x= -3, x= 0 and x=1.

Solution :

Given function is f(x) = -6 + 12 .

Simplifying above function, we get :

f(x) = 6

Now, the given function is independent of x.

So, for any value of x the the value of functions remains constant.

Hence, this is the required solution.

Answer:

X = 38.7°

Step-by-step explanation:

Reference angle = x

Opposite side length = 8 cm

Adjacent side length = 10 cm

Applying trigonometric ratio formula, we have:

[tex] tan(x) = \frac{8}{10} [/tex]

[tex] x = tan^{-1}(\frac{8}{10}) [/tex]

[tex] x = 38.7 [/tex]

x = 38.7° (to the nearest tenth)

Step-by-step explanation:

Total amount to generate at fundraiser = $8000

Amount donated by Bethany family = $60

The percentage of Bethany's donation towards the fundraiser is :

Let percentage = x

x% of 8000 = 60

x/100 * 8000 = 60

0.01x * 8000 = 60

80x = 60

Divide both sides by des by 80

80x / 80 = 60 / 80

x = 0.75

Answer:

C = 0.475

Step-by-step explanation:

you divide 5.70 by 12 and get that one bagel costs 0.475 cents. hope this helps!

c=40 is the answer

6x55=330 cents

$570-570 cents (570-330)÷(12-)

=240÷6 (division)

=40 cents

Thus, c=40

The unitary method is a method for solving a problem by first finding the value of a single unit and then multiplying the value of a single unit to find the required value.

The unitary method is a procedure that calculates the value of a single unit from the value of multiple units and the value of multiple units from the value of a single unit.

Simply put, the unitary method is used to find the value of a single unit from a given plural. For example, if the price of 40 pens is 400 rupees, the price of one pen would be: This can be done using a uniform method

Answer:

16

Step-by-step explanation:

The distance is given by

d = sqrt( (x2-x1) ^2 + ( y2-y1) ^2)

Since the x values are the same

d = sqrt(  ( y2-y1) ^2)

d = sqrt(  (( -6 - 10)^2))

d =  sqrt((-16) ^2)

d = 16

We can also just find the number of squares between the points since the x value is the same.
