A square pyramid is shown. What is the surface area of the pyramid? Enter your answer in the box.

Height = 6cm
Length = 2cm
Width = 2cm

Answer:

I don’t know but I know 27 times 630 plus 19 times 680 is 29,930 I’ve tried some other ways but it gets really close but not exact

Step-by-step explanation:

Answer:

a. the error is that he wrote 0.05 instead of 0.2

0.148835 ≈ 0.2

b.

0.2 = 2 × 0.1

0.2 = 2 × 10⁻¹

The mass is about 2 × 10⁻¹ kg

Answer:

Step-by-step explanation:

A = 3M

J = 2A

J = 6M

Marie = M

Andre = 3M

Jane = 6M

6M+3M+M = 840

10M = 840

M= 84 Pounds

Andre = 3M

Andre = 84*3

Andre has 252 pounds of apples.

Here's the solution,

figure 1.

by using trigonometry,

=》

[tex] \sin(60) = \dfrac{5 \sqrt{3} }{y} [/tex]

=》

[tex] \dfrac{ \sqrt{3} }{2} = \dfrac{5 \sqrt{3} }{y} [/tex]

=》

[tex] \dfrac{1}{y} = \dfrac{ \sqrt{3} }{2 \times 5 \sqrt{3} } [/tex]

=》

[tex] \dfrac{1}{y} = \dfrac{1}{10} [/tex]

=》

[tex]y = 10[/tex]

And,

=》

[tex] \cos(60) = \dfrac{w}{y} [/tex]

=》

[tex] \dfrac{1}{2} = \dfrac{w}{10} [/tex]

=》

[tex]w = 5[/tex]

So, values are :

figure 2.

Since, it's an isosceles triangle, w = y,

So, by pythagoras theorem :

=》

[tex] {w}^{2} + {y}^{2} = (7 \sqrt{2} ) {}^{2} [/tex]

=》

[tex] {w}^{2} + {w}^{2} = 98[/tex]

=》

[tex]2 {w}^{2} = 98[/tex]

=》

[tex] {w}^{2} = 49[/tex]

=》

[tex]w = \sqrt{49} [/tex]

=》

[tex]w = 7[/tex]

and we know, w = y, so their values will be equal to 7 units.

Answer:

1 fancy  15 plain

Step-by-step explanation:

F + P = 16

15F +10P = 165

Miltiplu the 1st by  -10:

-10F -10P = -160

15F +  10P = 165

Add both (10p is cancelled)

5F = 5

F =1

16-1 = 15   (15plain)

15 x10 =150

1x15 =15

  150 +15 = 165

Answer:

Parallelograms

Step-by-step explanation:

Answer:

x = 136°

Step-by-step explanation:

The opposite angles of a cyclic quadrilateral are supplementary, that is

x + 44° = 180° (subtract 44° from both sides )

x = 136°

Answer:

75 degrees

Step-by-step explanation:

Complementary angles equal 90 degrees together. That is the case with angle X and Y. Set an equation to describe the situation.

Y=1/5X

X=5Y

Now, set another equation:

X+Y=90

Substitute the first equation into the second one.

5Y+Y=90

6Y=90

Y=15

Substitute this once again:

X+15=90

X=75

Answer: For Mrs. Bhan, she pay 9.75 each visit for ten time so 10 ÷ 97.50

I don’t know how to answer for Mr. Stewart but I answer Mrs. Bhan. Hope this helps!

Answer:

Step-by-step explanation:

a)

eq 1) 97.50 = fee + 10x

eq 2) 83.50=fee +8x

subtract eq 2 from eq 1

14 = 2x

7 =x

each visit costs $7

b)

97.50 = fee + 10(7)

97.5- = fee +70

27.5 = fee

it costs $27.50 to sign up at the gym

( this seems like an expensive gym )

c)

gym costs = 27.50 + 7 per visit

cost = 27.50 +7x

( let's look for a less expensive gym :D  )

Answer:

any number between 83 and 0. [tex]0\leq x\leq 83[/tex]

Step-by-step explanation:

the number 1,548.4484 has the last two digits of 84.

And since the number has to be less than the other number and you can only switch the last two digits in the decimal's place. It has to be less than 84

Hope that helps :)

Answer:

the digit is 4, because that has 4484 but just put 4444

Answer:

6000

Step-by-step explanation:

so you have to divide 3000 and 6 to get 500

next you would do  500 times 6 equals = 3000

so now you would plus them and get 6000

now that is your answer

3428/2

1714 = 1700(rounded)

Answer:

there is a cluster from 1-4

there is a gap from 5-7

The spread is from 1-8

Step-by-step explanation:

These are all true if you look... there is a bunch from 1-4, there is none from 5-7, and all of them are within 1-8, but  the highest amount isn't at 3.

Answer:

m=1/2 & b=-2

Step-by-step explanation:

so in order to find m & b we need to distribute 1/2

y=1/2(x+6)-5

y=1/2x+3-5

y=1/2x-2

y=mx+b so

m=1/2 & b=-2

Answer: i dont know where u got m and b from but y=[tex]\frac{x}{2}[/tex] abd x= 2y+4 :)

Answer:

-4/13

Step-by-step explanation:

(17 , -19)  ; (4 , -15)

Slope = [tex]\frac{y_{2}-y_{1}}{x_{2}-x_{1}}[/tex]

          [tex]= \frac{-15-[-19]}{4-17}\\\\=\frac{-15+19}{4-17}\\\\=\frac{4}{-13}\\\\= \frac{-4}{13}[/tex]

Answer:

12 ft^3

Step-by-step explanation:

Given data

Dimension

Lenght= 2ft

Width= 3ft

Height= 2ft

The expression for the volume is

Volume= L*W*H

Substitute

V= 2*3*2

V= 12 ft^3

Hence the volume of the box is 12 ft^3

f(x) = 3x + 1

f(9) = 3(9) + 1

f(9) = 27 + 1

f(9) = 28

f(9) = 28. I hope this helps! I have a g00gle classroom where I help with algebra including this. If you are interested, please consider joining. I will post the class code in the comments if it would let me. Sorry it wouln't let me type g0ogle properly.

Answer:

28

Step-by-step explanation:

f(9) means when x = 9.

when x = 9,

f(9) = 3(9) + 1

= 27 + 1

= 28

Answer:# of cars: 1 | 0 | 0 | 0 | 2 | 4 | 5 | 3 | 0 | 2 | 2 | 1 |

Note: the answers are from left to right in order

Step-by-step explanation:

So this isn't as hard as it seems. You just count the X's and if there is like for example 1 x on 30 then the answer for 30 is 1 since there is only 1 X.
