HELP WILL GIVE BRAINLIESY​

I think I know this one.

Answer: V = 600 unit 2

Step-by-step explanation:

We have that

the volume of the rectangular pyramid is

V = (1/3) BH

where

B is the area of the rectangular face

H is the height of the pyramid

step 1

Find out B

B = (15)(10) unit 2

step 2

Find the volume

B = 150 unit 2

H = 12 unit

substitute

V = (1/3)(150)(12)

V = 600 unit 2

I hope this help you! :)

why do I have to write for it to send

Answer:

A

Step-by-step explanation:

Its a leg.

Answer:

A

Step-by-step explanation:

both a and b are legs. c would be the hypotenuse because it is across from the right angle.

Answer:

476 ÷ 17 = 28

Step-by-step explanation:

$17 an hour is multiplication. so, just do the opposite.

476 ÷ 17.

Answer:

2x+4y=22

-2x+2y=+8

6y=30

y=5

now

replace the value of y in equ i

2x +4y =22

2x+20=22

x=1

Answer: x = 1 y= 5

Step-by-step explanation:

2x + 4y = 22 -

2x - 2y = -8

--------------------

0+6y = 30

Y= 30/6= 5

Substituting,

2x+ 4*5= 22

2x+ 20 = 22

2x= 22-20 = 2

X=2/2=1

Answer:

No 4: the triangle are similar by congruency SAS(side angle side)

No 5: this is also similar by SAS

No 6: this is similar by AAS ( angle angle side)

No 7: this is similar by RHS ( right angle hypotenuse one side )

No 8: this pair of triangles are not similar

No 9: this is similar by SAS

No 10: this pair of triangles are similar by SAS ( side side side)

No 11: this triangle is similar by SSS

No 12: this triangle is similar by SSS

Answer:

Step-by-step explanation:

the third one

Answer:

18

Step-by-step explanation:

We will try to find the angle on the left side of the small triangle. So we have to use Tan.

SOHCAHTOA

TanФ = 12/8

[tex]Tan^{-1}[/tex] = 12/8   = 56.31°

So the other one is 33.69°  It's the top left one of the smaller triangle.

The top right side of the bigger triangle is 56.31 because they both add up to make 90°

Now that we have an angle of the bigger triangle we will find the x.

Tan 56.31 = x/12

x = 18

Theres probably a easier way but i dunno

Answer:

$3,442.40

$3,057.60

Step-by-step explanation:

The computation of the each investment is as follows:

let us assume the one investment be x

And, the other investment be y

So

According to the question

x + y = $6,500

And,

-7x + 8y = $364

Now multiply by 7 in equation 1

7x +  7y = $45,500

-7x + 8y = $364

15y = $45,864

y = $3,057.60

x = $6,500 - $3,0657.60

= $3,442.40

Answer:

Angle 1= 147

Angle 2= 33

Step-by-step explanation:

(4a+7) + (a-2) = 180

4a+7+a-2=180

5a+5=180

5a=175

a= 35

plug in 35 for A to find measurements

4(35) +7 = 147

(35) -2= 33

Answer:

15

Step-by-step explanation:

Pythagorean theorem: the sum of the squares on the legs of a right triangle is equal to the square on the hypotenuse.

C = the square root of A squared + B squared.

plug in the numbers

C = the square root of 9 squared + 12 squared = 15

Answer:

15

Step-by-step explanation:

[tex] {9}^{2} + {12}^{2} = c ^{2} \\ 81 + 144 = {c}^{2} \\ 225 = {c}^{2} \\ \sqrt{225} = c \\ \sqrt{225} = 15[/tex]

41.12 is the answer

so the perimeter is cirumference of circle + 16

25.12 + 16

41.12 is the perimeter

Answer:

-7  -4  0 1 7

Step-by-step explanation:

x=0

x²-49=0

x²=49

x=±7

x²+3x-4= ² + 4 − − 4= ( + 4 ) − 1 ( + 4 )=(x+4)(x-1)=0

x+4=0

x=-4

x=1

Answer:

This is irrational. Pretty much anything with pi is irrational.

Step-by-step explanation:

Pi is irrational, so this irrational as well.

Answer:

The number π is an irrational number, so it cannot be expressed as a fraction. Since π is irrational, it follows that π/2 is also irrational.

Answer:

A. 2^4 . 2^-3 . 2^4 . 2

Step-by-step explanation:

Option A,

2^4 . 2^-3 . 2^4 . 2

= 2^4 . 2^-3 . 2^4 . 2^1

= 2^( 4 + 4 + 1 - 3 )

= 2^( 9 - 3 )

= 2^6

= 64

So, Option A is the correct answer.

Answer:

3 people

Step-by-step explanation:

If 20 people each bring 3 food dishes to an awards banquet, the total amount of food brought will be (20 * 3) = 60foods

If the dishes are shared equally by 180 people at the banquet, then;

60foods = 180 people

1 food = x

Cross multiply

60* x = 180

60x = 180

x =180/60

x = 3

Hence 3 people will share 1 dish

Answer:600

Step-by-step explanation:

Answer:

20

___ x X = 120

20x = 120

divide by 20 on both sides.

x = 6

Answer:

y = 3x + 1

Step-by-step explanation:

y = 3x + b

-5 = -6 + b

1 = b

Answer:

502.4 cubic unit

Step-by-step explanation:

Given data

The parameter for the cylinder is as follows

Height h= 10units

Radius r= 4 units

We know that the expression for the volume of a cylinder is

V= πr^2h

substitute

V= 3.14*4^2*10

V= 3.14*16*10

V= 502.4 cubic unit

Hence the volume is  502.4 cubic unit
