Find the surface area of a square pyramid if the area of the base is 324 cm^2 and the height is 40 cm.

-56 is the whole number

0.5 is the fraction part (0.5 = 1/2)

If we put them back together, we get;

-56 1/2

Best of Luck!

Hey there!

[tex](x-8)^2=25[/tex]

To solve this equation, you will need to simplify both sides.

[tex]x^2-16x+64=25[/tex]

Now we will need to minus(subtract) 25 from both sides of the equation.

[tex]x^2-16x+64-25=25-25=x^2-16x+39=0[/tex]

Now we will need to factor out the left side.

[tex](x-3)(x-13)=0[/tex]

In our last step, we will need the set factors equal to zero.

[tex]x-3=0\\x-13=0\\x=3(ANSWER)\\x=13(ANSWER)[/tex]

Hope this helps!

Answer:

The price would be decreased by 18 bozats

Step-by-step explanation:

The following information is given in the question

x = number of kilograms of snig sold

P = Price per kilogram

And, the equation is

p = 300 - 18x

Now if an extra kilogram is sold so it should be x+1

Now the new price is

New price = 300 - 18(x + 1)

= 300 - 18x - 18

Therefore the price would be decreased by 18 bozats

Given that:

Price-demand equation is

[tex]p=300-18x[/tex]

where, x is the number of kilograms of snig sold, and p is the price per kilogram of snig in the local currency, the Boat.

To find:

The price which needs to decrease to sell an additional kilogram of snig,

Solution:

We have,

[tex]p=300-18x[/tex]

If x=1, then

[tex]p=300-18(1)[/tex]

[tex]p=300-18[/tex]

[tex]p=282[/tex]

It means, the price is 282 if 1 kg of snig sold.

Similarly,

If x=2, then

[tex]p=300-18(2)[/tex]

[tex]p=300-36[/tex]

[tex]p=264[/tex]

It means, the price is 264 if 2 kg of snig sold.

Change in price if sales increased by 1 kg is

[tex]264-282=-18[/tex]

Here, negative sign means decrease in price.

Therefore, the price needs to decrease by 18 to sell an additional kilogram of snig.

Answer: [tex]tan(\frac{13\pi }{4})-cos(\frac{\pi }{3})=\frac{1}{2}[/tex]

Step-by-step explanation:

To find [tex]tan(\frac{13\pi }{4})-cos(\frac{\pi }{3})[/tex], we first need to understand the unit circle. Let's find the value of tan and cos before we subtract them.

[tex]tan(\frac{13\pi }{4} )[/tex] is the same as [tex]tan(\frac{5\pi }{4} )[/tex]. The point for [tex]\frac{5\pi }{4}[/tex] is (-0.5,-0.5). Tangent is [tex]\frac{sin}{cos}[/tex]. Since sin and cos are both -0.5, we can divide them.

[tex]\frac{-0.5}{-0.5} =1[/tex]

Now, we know that [tex]tan(\frac{13\pi }{4} )=1[/tex]. All we have to do is find [tex]cos(\frac{\pi }{3})[/tex].

[tex]cos(\frac{\pi }{3})=\frac{1}{2}[/tex]

Now that we know the values of both, we can directly subtract them.

1-0.5=0.5

Therefore, [tex]tan(\frac{13\pi }{4})-cos(\frac{\pi }{3})=\frac{1}{2}[/tex].

Answer:

7 is greater than -3

Step-by-step explanation:

7 is positive meaning is more than any negative number

Answer:

7 is greater

Step-by-step explanation:

Graph it on a number line. 7 is on the positive side and -3 is the negative side, and positive numbers always are bigger than negative numbers.

Answer:

The term that best describes a figure formed by three segments connecting three non-collinear points is:

Triangle.

Step-by-step explanation:

Step-by-step explanation:

We know that with the help of just one point we can't form any figure.

With the help of two points a line segment can be formed.

And with the help of three points if the three points are collinear a triangle can be formed.

Hence, the term that best describes a figure formed by three segments connecting three non-collinear points is:

Triangle.

Answer:

Perfect cube

Step-by-step explanation:

5 x 5 x5 = 125

5x5= 25

25x5 =125

Answer:

It is a perfect cube with sides of 5.

Step-by-step explanation:

If 125 was a perfect square, there would be a whole number A which, squared, would give us 125.

[tex]A^2 = 125\\A = \pm 11.18...[/tex]

We can see that the roots are not whole numbers.

(Tip: without a calculator, we can find this by testing [tex]10^2 \ 11^2\ 12^2[/tex] to see if any give us 125. We get 100, 121, 144 respectively. None of them is 125.)

If it was a perfect cube, there would be a whole number B which, cubed, would give us 125.

[tex]B^3 = 125\\B = \sqrt[3]{125} \\B = 5[/tex]

As we can see, there IS a whole number B: 5 !

(Without a calculator, like the previous one, we could try [tex]4^3\ 5^3\ 6^3[/tex] and we'd find that [tex]5^3[/tex] = 125)

Answer: It is a perfect cube with sides of 5.

Answer: i have no idea

Step-by-step explanation:

Answer:

y = (13/6)(b - 12)

Step-by-step explanation:

b = 6/13 y + 12

Subtract 12 from both sides.

b - 12 = 6/13 y

Multiply both sides by 13/6.

(13/6)(b - 12) = y

y = (13/6)(b - 12)

Answer:

60 & 55

Step-by-step explanation:

1. the sum of the angles 1; 2 and 3 is 180°, then

m∠1=m∠2=m∠3; ⇒m∠3=60°;

2. m∠3=m∠r; ⇒ m∠r=60°;

3. m∠α= 180-(m∠r+65°)°; ⇒ m∠α=55°

all the details are in the picture.

Answer:

5.63

Step-by-step explanation:

Angle NLM is equal to KLM - KLN.

Since KLM = 137° and KLN = 47°, NLM = °90. (Maybe it doesn't look like a right angle, but the math doesn't lie.)

Since NLM = 16y, then 90 = 16y.

Dividing both sides by 16, we find that:

y = 5.625

Answer:

y = 5.63

Explanation:

This answer is 5.23 because ∠KLN plus ∠NLM are equal to ∠KLM or 137°.

If you subtract 47 from 137 you will get 90. If you divide 90 by 16 you will get 5.625 which is rounded to 5.63.

Answer:

35x+72y

Step-by-step explanation:

well you are subtracting the terms 3x and -11y from the terms 38x and 61y. so to start you multiply 3x and -11 by negative one to get rid of the parentheses. you then you combine like terms.

Answer:

[tex]\frac{\left(t-h\right)}{k}\\[/tex] = g

Step-by-step explanation:

Subtract the h

t = h+kg

-h  -h

you get:

t-h=kg

now divide the k from both sides

[tex]\frac{\left(t-h\right)}{k}\\[/tex] = [tex]\frac{\left(kg\right)}{k}[/tex]

so,

[tex]\frac{\left(t-h\right)}{k}\\[/tex]=g
