Compare. Write <, >, or =. Write the strategy you used. 2/3 ------ 7/8

My favorite strategy is the criss cross method. \frac{2}{3} ?  \frac{7}{8}
Take the numerator of the first fraction (2), and the denominator of the second fraction (8) and multiply them. The value 16 is now up on the left side, imaginary. (ALWAYS PUT THE PRODUCT ON THE SIDE WITH THE NUMERATOR) Now multiply the other diagonal. 3(7)=21. The 21 is on the right side. Now do 16 ? 21
Is it <, >, or =? The answer is <

Luba_88 [7]

Answer:

Step-by-step explanation:

Step: 1: Convert mixed fraction to improepr fraction.

Step: 2 : Find the LCM of 4 , 5 = 20

Step 3: Find equivalent fractions with denominator as 20

Step 4: Now subtract.

3\dfrac{1}{4}-1\dfrac{3}{5}=\dfrac{13}{4}-\dfrac{8}{5}

             \sf = \dfrac{13*5}{4*5}-\dfrac{8*4}{5*4}\\\\\\     = \dfrac{65}{20}-\dfrac{32}{20}\\\\\\    = \dfrac{65-32}{20}\\\\\\    = \dfrac{33}{20}\\\\  \\    = 1 \dfrac{13}{20}

Which of the following functions has the largest value when x = 3? c(x) = 3x2 + 5x + 22 j(x) = 12x a(x) = 9x
Olin [163]

To determine the function which has the largest value at x=3,

We will calculate the value of each function by substituting the value of x=3 in each of the given function.

Let us consider the first function,

c(x)=3x^{2}+5x+22

c(3)=3\times 3^{2}+5 \times 3+22

c(3)=27+15+22

c(3)=64

Let us consider the second function,

j(x)=12x

j(x)=12 \times 3 =36

Let us consider the third function,

a(x)=9x

a(x)=9 \times 3=27

Therefore, the function c(x) has the largest value at x=3.

Anarel [89]

Answer:

f(x) = 960730(1.013)^{x}

Step-by-step explanation:

The number of people in Pinellas country has been changing at a rate of 1.3% per year.

If in the year 2016, there were 960,730 people in the country and if x represents the number of years since 2016, then the function that models the number of people in the country after x years since 2016 is

f(x) = 960730(1 + \frac{1.3}{100})^{x}

⇒ f(x) = 960730(1 + 0.013)^{x}

⇒ f(x) = 960730(1.013)^{x} (Answer)
