tommy likes to run up and down and "up" escalator. Going up, he can cover 30 steps in 6 seconds. Going down, it takes him 15 sec

NemiM [27]

Answer:

3 steps per second.

Step-by-step explanation:

Find the Unit Rates of each going up and down:

--> 30/6 unit rate is 5 steps per second.

--> 30/15 unit rate is 2 steps per second.

Now subtract them to get the amount if the elevator wasn't moving:

--> 5-2= 3.

Geometry math question no Guessing and Please show work thank you

hichkok12 [17]

we will use formula

$\theta=\frac{180(n-2)}{n}$

where

theta is angle

n is number of sides

we are given

n=15

we can plug it

$\theta=\frac{180(15-2)}{15}$

now, we can solve for theta

$\theta=\frac{60(15-2)}{5}$

$\theta=12*13$

$\theta=156$

so,

option-D.........Answer

Graph the image of the given triangle under a dilation with a scale factor of –4 and center of dilation (0,0).

Dvinal [7]

Step-by-step explanation:

Hey there!

The coordinates of a triangle are;

A (1,2)
B (1,-2)
C (-2,-2)
Scale factor = -4 and centre at (0,0)

Now, We have;

P(x,y)----------- P'(kx, ky)

Keep formula;

A(1,2)---------- A'(-4×1 ,-4×2)

= A'(-4, -8)

B(1,-2)------------- B'(-4,8)

C(-2,-2)-------------C'(8,8)

[ The A' should be kept in (-4,-8). There was no place in this graph so, i kept it just below -7. Please while plotting remember to keep it on "-8".]

Hope it helps..

The truth table represents statements p, q, and r. p q r q ∧ r A T T T T B T T F F C T F T F D T F F F E F T T T F F T F F G F F

nignag [31]

Solution:

q ∧ r : q and r

q r q∧r

T T T

T F F

F T F

F F F

p ∨ (q∧r)

p OR (q AND r)

p q∧r p∨(q∧r)

F T∧ T=T T

F F∧T = F F

F T ∧ F=F F

F F ∧ F =F F

If P is false , The row which represents when p ∨ (q ∧ r) is true is →→F T T T

Which is Option E.
