Answer:

1, 4/5,2/5

Step-by-step explanation:

y = 5x

Let y = 5

5 = 5x

Divide by 5

5/5 =5x/5

1=x

Let y=4

4 =5x

Divide by 5

4/5 =5x/5

4/5 =x

Let y=2

2 =5x

Divide by 5

2/5 =5x/5

2/5 =x

Jana planted 30 tulips. A total of 2/3 of those tulips have bloomed. How many of the tulips that Jana planted have bloomed?

20 tulips. 2/3=20/30 when you multiply both the denominator and numerator by 10.

(4/9)^-1= A. -4/9 B. 9/4 C. -9/4

Romashka-Z-Leto [24]

Answer: 9/4

Step-by-step explanation: Think of $(\frac{4}{9})^{-1}$ as $\frac{4^{-1} }{9^{-1}}$ .

Now, we can change 4⁻¹ to 4¹ by moving it to the denominator and

we can change 9⁻¹ to 9¹ by moving it to the numerator.

So we have 9¹/4¹ which simplifies to 9/4.

A car advertisement claims that a certain car can accelerate from rest to 70 km/hr in 7 seconds find the car acceleration

iVinArrow [24]

Answer:

acceleration $\approx 2.78\,\,\frac{m}{s^2}$

Step-by-step explanation:

The acceleration is the change in velocity per unit of time.

Therefore to have this rate in appropriate units that can combine, we re-write the change from 0 to 70 km/h in meters per second using:

$70 \frac{km}{h} = \frac{70000}{3600} \frac{m}{s}$

so in this case the acceleration becomes:

$accel=\frac{change\,\,vel}{change\,\,time} =\frac{70000m}{3600\,*7\,s^2} \approx 2.78\,\,\frac{m}{s^2}$
