$0.\overline{5} + 0.19\overline{4}$.
Scilla [17]

Answer:

0.\overline{5} + 0.19\overline{4}=0.75

Step-by-step explanation:

Given expression:

0.\overline{5} + 0.19\overline{4}

To evaluate the expression.

Solution.

The values are

0.\overline{5}=0.555555......  

Let X=0.555555..... -----------1                  

Multiplying 10 both sides.

10X=5.555555....----------2

Subtracting 1 from 2.

 10X=5.555555....

- X=0.555555.....

-------------------------------------------

9X=5.0

Dividing both sides by 9.

\frac{9X}{9}=\frac{5}{9}

X=\frac{5}{9}

0.19\overline{4}=0.194444....

Let Y=0.1944444..

Multiplying both sides by 100

100Y=19.44444..------------3

Multiplying 1000 both sides.

1000Y=194.4444....----------4

Subtracting 3 from 4.

 1000Y=194.4444....

- 100Y=19.44444.....

-------------------------------------------

900Y=175.0

Dividing both sides by 900.

\frac{900Y}{900}=\frac{175}{900}

Y=\frac{175}{900}

So, we can evaluate the given expression as:

⇒ 0.\overline{5} + 0.19\overline{4}

⇒ X+Y    

⇒ \frac{5}{9}+\frac{175}{900}

Taking LCD = 900

⇒ \frac{5\times 100}{9\times 100}+\frac{175}{900}

⇒ \frac{500}{900}+\frac{175}{900}

Adding numerators.

⇒ \frac{500+175}{900}

⇒ \frac{675}{900}

⇒ 0.75 (Answer)

Please help me answer this, I don't get what I'm supposed to do TvT
kompoz [17]

Answer:

You save 86 cents per pound.

Step-by-step explanation:

According to the given problem, grocery store B charges chicken 5 pounds of chicken for $38.20. Consider finding the unit price:

To find the unit price of any item, do the following calculation:

Total Price / Total amount = $$$ per amount.

The unit price of store b is \frac{38.20}{5}=7.64 . In other words, every pound of chicken costs $7.64 at store b.

For store a, we are provided with a table. Given how the question is being asked, we should <u>expect a higher unit price</u>. We can take any charge to find the unit price since the price should be consistent no matter how many pounds you buy. I will calculate the first row:

\frac{12.75}{1.5}=8.5

In other words, every pound of chicken costs $8.50 at store a. <u>This price is higher</u>. You can verify this is the correct unit price by multiplying the unit price with any amount of pounds provided at the table. You should get the total cost.

So, now that we have both unit prices, we can calculate the difference to find out how much we save per pound when choosing store b:

8.50-7.64=0.86.

Which equation represents an exponential function that passes through the point (2, 80)?
Lena [83]

The function f(x) = 5(x)⁴, and f(x) = 5(4)ˣ represents the function that passes through the point (2, 80) option second and fourth are correct.

<h3>What is an exponential function?</h3>

It is defined as the function that rapidly increases and the value of the exponential function is always a positive. It denotes with exponent \rm y = a^x

where a is a constant and a>1

We have; an exponential function that passes through the point (2, 80).

f(x) = 4(x)⁵

Plug (2, 80) in the abovew function:

f(2) = 4(2)⁵ = 128 (false)

f(x) = 5(x)⁴

Plug (2, 80) in the abovew function:

f(2) = 5(2)⁴ = 80 (true)

f(x) = 4(5)ˣ

f(2) = 4(5)² = 100 (false)

f(x) = 5(4)ˣ

f(2) = 5(4)² = 80 (true)

Thus, the function f(x) = 5(x)⁴, and f(x) = 5(4)ˣ represents the function that passes through the point (2, 80) option second and fourth are correct.
