Answer: See explanation

Step-by-step explanation:

Let the base be represented by x.

Therefore, the height will be = 3 × x = 3x

Since Area of a triangle = 1/2 × base × height

1/2 × x × 3x = 73.5

3x²/2 = 73.5

3x² = 73.5 × 2

3x² = 147

x² = 147/3

x² = 49

x = ✓49

x = 7

Base = 7cm

Height = 3 × 7 = 21cm

beks73 [17]

Answer:

(mxt) miles

Step-by-step explanation:

$speed = m \: miles \: per \:minute \\ time \: = t \: minutes \\ speed = \frac{distance}{time} \\ m = \frac{d}{t} \\ m \times t \: = d \\ d = (m \times t)miles$

hope that this is helpful.

Probably really simple but my dumb butt don’t know it :/

The answer is: 454 miles. You have to divide 2951 miles by 6.5 hours so 2951/6.5=454.

Answer:

Step-by-step explanation:

Let's solve your equation step-by-step.

(y+4)(3y−5)=0

Step 1: Simplify both sides of the equation.

3y2+7y−20=0

Step 2: Factor left side of equation.

(3y−5)(y+4)=0

Step 3: Set factors equal to 0.

3y−5=0 or y+4=0

y=5 /3

or y=−4

We need to use the following formula of distance .

Distance= speed * time .

For the first time

distance = 6r

And let the average rate for the second time be s

So distance = 5s

Since distance remains same, so we get

6r=5s

Now we have to solve for s. And for that we need to get rid of 5, by dividing both sides by 5, that is

$s =\frac{6r}{5}$

And that's the required average rate for the second trip .
