Answer:

X=5or -2

Step-by-step explanation:

x²-3x-10=0

x²-(5-2)x-10=0

x²-5x+2x-10=0

x(x-5)+2(x-5)=0

(x-5)(x+2)=0

either Or

x-5=0 x+2=0

x=5 x=-2

(x-5) = 0 or (x+2)=0
so x could be 5 or -2
i guess, u can check it with calculator

A helicopter hovers at an altitude that is 1000 feet above a mountain of altitude 5210 feet. A second, taller peak is viewed fro
ehidna [41]
Given: 

Height of Mountain A = 5210 feet
Distance of Mountain A from a helicopter above the peak = 1000 feet
Angle of depression:
       Mountain B to helicopter = 43 degrees
       Mountain B to Mountain A = 19 degrees
 
 First, draw an illustration and label the enumerated given values.

Observe that there are two right triangles formed:

From the triangle formed by the helicopter and Mountain B, 

let x = total height of mountain B
     y = leg of first triangle (helicopter and mountain b)
     h = hypotenuse
Use the Pythagorean Theorem:

cos (43) = y / h

From the second triangle formed by mountain b and a,

cos (19) = (1000 + y) / h

solve for h and y

then, solve for the height of Mountain B:

x = 1000 + y + 5210

A bus and a train leave the same station at the same time and travel in the same direction along parallel routes. The train runs
MrMuchimi

Answer:

Smallest rate for the train is 50 mph and largest is 60 mph.

For the bus it is 25 and 30 mph.

Step-by-step explanation:

If the speed of the train is 2x then speed of the bus is x mph, and the train travels twice as far as the bus in a given time.

Distance = speed * time

For the largest rate:

d =  2x * 0.5   for the train

x = d

0.5d  =  x       for the bus

d - 0.5d = 15

0.5d = 15

d = 30

So the rate for the train =  30 / 0.5 = 60 mph.

In a similar fashion we can show that the smallest rate for the train is

25/ 0.5 = 50 mph.

at a basketball game a vendor sold a combined total of 116 sodas and hotdogs. The number of hotdogs sold were 36 less than the n
algol [13]

Answer:  76 Sodas and 40 hot dogs

Step-by-step explanation:

Let S and H represent the numbers of Sodas and Hot dogs.

We are told that:

S + H = 116

We also see that:

H = S - 36

==

Take the second equation's value for H (S - 36) and use it in the first:

S + H = 116

S + (S-36) = 116

2S = 152

S = 76

and therefore H = S - 36, or 40.

76 + 40 = 116  [Checks]

76 Sodas and 40 hot dogs
