Triangles MNQ and MOP are similar. What is the slope of segment MO?
asambeis [7]

Answer:

D. 3/2

Step-by-step explanation:

The scale factor is 1/2 from OP / NQ = 1/2. Because of that, MQ is equal to half of MP and QP is equal to half of MP. Therefore, QP = MQ = 2. The slope of MO is rise over run which is 6 / 4 or 3 / 2.

You should use the ratio so 

2/ 4  = 6.5 / n  

n= 6.5 x 4  / 2 =  13 inches 


2- for two hours ------> four inches of snow 
for x hours -----> y inches of snow 
the equation is 
2/4 = x/ y 

x= 2y / 4 
 for x is the hours and y is the inches

5 gr granula ----------------------> 1750 calories 
2 gr granula ----------------------> n ?? calories 

by cross multiplication 
n = 2 x1750 / 5 =  700 calories .

2-
she wants to eat 175 calories so 
u put granula under granula  and calories under calories to make this cross 

<span>5 gr granula ----------------------> 1750 calories 
</span>??? m granula ---------------------> 175 calories 
<span>by cross multiplication </span>
m = 175 x 5 / 1750 =  0.5 gr of granula

Type the correct answer in each box. The reflection of point S across the y-axis is point . The reflection of point Q across the
tresset_1 [31]

Answer:

S' = (-5,-5)

Q"=(-5,-5)

Step-by-step explanation:

Given

S = (5,-5)

Q= (5,5)

Solving (a): Reflect S across y-axis

The rule to reflect across y-axis is:

(x,y) \to (-x,y)

So, we have:

S(5,-5) \to S'(-5,-5)

Hence:

S' = (-5,-5)

Solving (b): Reflect Q across x and y-axis

The rule to reflect across x-axis is:

(x,y) \to (x,-y)

So:

Q(5,5) \to Q'(5,-5)

The rule to reflect across y-axis is:

(x,y) \to (-x,y)

So:

Q'(5,-5) \to Q"(-5,-5)

Hence:

Q"=(-5,-5)

Is 1044 divisible by 2,3,5,6,9 or 10
Travka [436]
1044 is divisible by 2 as it is an even number
To check whether it divides by three, just add all the digits and see if that is divisible by three, so 1+0+4+4 is 9 and 9/3= 3, so 1044 is divisible by three
Not divisible by 5 because it does not end in 5 or 0
Divisible by 6, 1044/6= 174
Divisible by 9, 1044 /9 gives 116
Not divisible by 10 because it does not end in 0
