Answer:

answer is c

Step-by-step explanation:y =

−0.3x

The given equations are in slope-intercept form, y = mx + b, where b represents the y-intercept.

Proportional relationships must pass through the origin. Therefore, the y-intercept for the equation must be 0. The y-intercept for y = −0.3x is 0.

Answer:

Single Equivalent Discount % on final price  = 41.58%

Explanation:

The grill was initially priced at $769.99 and was discounted to $550.54 which is 28.5% ((550.54/769.99)-1)*100

and then further discounted by 18.3% ((449.79/550.54)-1)*100 to $449.79.

but if we want to get the single discount rate for $449.79 (final price), we have to compare it with very first original price of $769.99 so the formula will be:

((449.79/769.99)-1)*100 = 41.58% which shows the actual discount % versus the original price of the grill.

A ramp is used to load a snowmobile onto the back of a pickup truck. The truck bed is 1.3m above the ground. For safety, the ang
kiruha [24]

Answer:

2.02 m

or 2 m 2 cm

Step-by-step explanation:

Imagine a triangle containing the 40° angle and that this angle is at the left.  Then the height of the truck bed is 1.3 m and the "shortest possible length of the ramp" is the hypotenuse of this triangle.  We need to find the length of this ramp, that is, the length of the hypotenuse.  

The sine function relates this 40° angle and the 1.3 m height of the truck bed:

sin 40° = opp / hyp = 1.3 m / hyp

which can be solved for 'hyp' as follows:

              1.3 m

hyp = ----------------- = (1.3 m) / 0.6428)

             sin 40°

                                                                                  1.3 m

Thus, the length of the ramp must be less than -------------- or 2.02 m

                                                                                 0.6428

where this last result is to the nearest cm.

If the ramp is shorter the angle of the ramp will be smaller and the ramp angle considered safer.

Marrrta [24]

Answer:

D, E, and A

Step-by-step explanation:

Because 4 is also equivelent to square root of 16 and square root of 16 times square root of 3 is equal to square root of 48 which is D, and E is also correct because square root 24 x square root 2 is also square root 48 and same concept with A.
