Brums [2.3K]3 years ago
6 0
The unit rate will be in revolutions per second. That means divide number of revolutions by number of seconds.

first convert from mixed fraction.
6 2/5 = 32/5 revolutions
2 2/3 = 8/3 seconds

32/5 ÷ 8/3
flip multiply
32/5 × 3/8 = 12/5 revolutions per second

12/5 = 2 2/5 revolutions per second

When 4(0.5x+2.5y-0.7x-1.3y+4) is simplified, what is the resulting expression?
padilas [110]

Answer:

-0.8x + 4.8y + 16

Step-by-step explanation:

4(0.5x+2.5y-0.7x-1.3y+4) = 4( 0.5x - 0.7x  + 2.5y - 1.3y + 4)

= 4( -0.2x  + 1.2y + 4)

= 4*(-0.2x)  + 4 *1.2y + 4*4

= -0.8x + 4.8y + 16

Jasmine buys 3 T-Shirts and 3 Hats for $11.25. The next day, he buys 4 T-Shirts and 2 Hats for $10. How much does each T-Shirt a
leonid [27]

Answer: Each shirt costs $1.25, and each hat costs $2.5.

Step-by-step explanation:

Let x= Cost per T-shirt, y = Cost per Hat.

As per given,

3x+3y=11.25        (i)

4x+2y=10             (ii)

Multiply 4 to equation (i)

12x+12y=45          (iii)

12x+6y= 30             (iv)

Eliminate (iv) from (iii), we get

6y= 15

⇒ y = 2.5

Put value of y in (i)

3x+3(2.5)=11.25

⇒3x+7.5=11.25

⇒3x= 3.75

⇒x= 1.25

Hence, each shirt costs $1.25, and each hat costs $2.5.

How many times bigger is 3x10^8 then 6x10^7​? Plz put an explanation
myrzilka [38]

Answer:

240000000 times bigger.

If we solve 3x10^8 we get 300000000

Then if we solve for 6x10^7 we get 60000000

Subtract those two using long subtraction to evaluate and we get 240000000

A. A newborn red panda weighs 100 grams. A
77julia77 [94]

Answer:

y=100\cdot (1.07)^d

Step-by-step explanation:

Find the expression to represent how much you would expect a cub to weigh d days after it's born as exponential growth function y=a\cdot b^d, where a is the initial panda's weight and b is the rate of growth.​

A newborn red panda weighs 100 grams, then a=100.

A healthy cub gains about 7% of its newborn weight per day, then

b=1+0.07=1.07

Hence,

y=100\cdot (1.07)^d
