Answer:

Option (2)

Step-by-step explanation:

Option (1).

Time taken by Tina to walk = 56 minutes

Time taken by her sister to walk the same distance = x minutes

If both the sisters take the same time to walk, then

x = 56 minutes

Option (2).

Let the height of Tina = x inches

and the height of her brother = 56 inches

if Tina is shorter than her brother then,

x < 56 inches

Option (3).

Tina's dog weighed two months ago = 56 pounds

If the dog gained the weight in two months then weight before 2 months will be less than the present weight.

Let the weight of her dog is x pounds now,

x > 56 pounds

Option (4).

Amount with Tina = $x

Cost of the camera = $56

If the money with Tina has enough money to buy the camera, then the amount of money with her will be higher than the cost of the camera.

x > $56

Option (2) will be the answer.

What is the equation of a line in general form that passes through the point (1,-2) and has a slope of 1/3

ser-zykov [4K]

Answer:

(y+2) = (1/3)(x-1)

Answer in point-slope form, you can rearrange this into the form which you need.

Step-by-step explanation:

recall that the general point-slope form of a linear equation looks like :

(y - y₁) = m(x - x₁)

where m is the slope and (x₁,y₁) is any point on the line

here we are given m = 1/3 and (x₁,y₁)=(1,-2)

simply substitute this info into the general equation above

(y - y₁) = m(x - x₁)

(y - (-2) ) = (1/3)(x - 1)

(y+2) = (1/3)(x-1) Answer in point-slope form, you can rearrange this into the form which you need.

June and Armando are each in a hot air balloon. Armando's balloon is at a slightly higher elevation than June's. The two balloon

Mandarinka [93]

Answer:

46.63 ft

Step-by-step explanation:

I've drawn and attached a triangle diagram to represent this elevation and distance of balloons.

Now, from the diagram attached, we can see the angle at which June must look up to see Armando is 25°.

Also, the height of Armando above June is represented by "x".

Thus, using pythagoras theorem, we can find x.

Thus;

x/100 = tan 25

x = 100 × tan 25

x = 100 × 0.4663

x = 46.63 ft
