2.8 is greater than 2.78 :)

If you look in the tens place and compare the two numbers, you will see that 8 is greater than 7. That’s how you know that 2.8 is greater than 2.78

2.8 is greater than 2.78 because 2.8 would basically be 2.80 so you can just add 0 at the end cause that wouldn’t change anything. So 2.80 you can see is greater than 2.78 because .80 > .78

In front of a store, there is a row of parking spaces. Cars park parallel to one another, with the front of each car facing the

Gelneren [198K]

The width used for the car spaces are taken as a multiples of the width of

the compact car spaces.

Correct response:

The store owners are incorrect

<h3 /><h3>Methods used to obtain the above response</h3>

Let x represent the width of the cars parked compact, and let a·x represent the width of cars parked in full size spaces.

We have;

Initial space occupied = 10·x + 12·(a·x) = x·(10 + 12·a)

New space design = 16·x + 9×(a·x) = x·(16 + 9·a)

When the dimensions of the initial and new arrangement are equal, we have;

10 + 12·a = 16 + 9·a

12·a - 9·a = 16 - 10 = 6

3·a = 6

a = 6 ÷ 3 = 2

a = 2

Whereby the factor a < 2, such that the width of the full size space is less than twice the width of the compact spaces, by testing, we have;

10 + 12·a < 16 + 9·a

Which gives;

x·(10 + 12·a) < x·(16 + 9·a)

Therefore;

The initial total car park space is less than the space required for 16

compact spaces and 9 full size spaces, therefore; the store owners are

incorrect.

16-5(3t-4)=8(-2t+11) How to Solve

Hunter-Best [27]

16 - 5(3t - 4) = 8(-2t + 11) use distributive property: a(b + c) = ab + ac

16 - (5)(3t) - (5)(-4) = (8)(-2t) + (8)(11)

16 - 15t + 20 = -16t + 88

36 - 15t = -16t + 88 subtract 36 from both sides

-15t = -16t + 52 add 16t to both sides

t = 52

The number of customers for a new online business can be modeled by y = 8x2 + 100x + 250, where x represents the number of month

kenny6666 [7]

The best prediction for the number of customers is 5450.

To find this value, you just need to plug in 20 for x into the expression. Then, evaluate it using the order of operations.

8(20)^2 + 100(20) + 250
8(400) + 100(20) + 250
3200 + 2000 + 250
5450

Answer:

Given -

radius of cylinder = 6 ft
height of cylinder = 14 ft

Now ,

$volume = \pi \: r {}^{2} h \\ = > \frac{22}{\cancel{7}} \times 6 \times\cancel{ 14} \\ \\ = > 22 \times 6 \times 2 \\ = > 264 \: ft {}^{3}$
