Which set of rational numbers are orders from least to greatest? A) -1, -1 1/2, -1 1/4, -1 7/8 B)-1 7/8, -1 1/2, -1 1/4, -1

Semmy [17]

Answer:

-1 7/8, -1 1/2, -1 1/4, -1

Step-by-step explanation:

First note that the negative value closer to zero on the number is greater. an those far from zero will be the least

According to the given option, we can first express the fractions as percentage as shown

-1 7/8 = -15/8 * 100 = -187.5%

-1 1/2 = -3/2 * 100 = -150%

-1 1/4 = -5/4 * 100 = -125%

-1 = -1 * 100 = -100%

Based on the explanation above, the least value is -187.5% and the greatest value is -100%

Rearranging from least to greatest is expressed as -187.5%,-150%, -125%, -100%

According to their respective fractions;

-1 7/8, -1 1/2, -1 1/4, -1

You have to spend money to make money ! You purchase a mix of newspaper ads and online ads. Each newspaper ad cost $18.50 and ea

SpyIntel [72]

Answer:

You buy six newspaper ads & eighteen social media ads.

Step-by-step explanation:

First, we change ads into variables to be more easier to calculate :

Let newspaper = x

Let social media = y

Second, make this variables into an equation, given that you purchase a total of 24 ads :

x + y = 24 (first equation)

Next, given that x = $18.50 & y = $26.50 & spent a total of $588 so you can make another equation :

18.50x + 26.50y = 588 (second equation)

Now, solve this simultaneous equation using elimination or substitution (depends on you) :

substitution =>

x + y = 24 ----------(1)

18.50x + 26.50y = 588 ---------(2)

(1)=> y = 24 - x ------(3)

(3)=>(2) 18.5x + 26.5(24-x) = 588

18.5x + 636 - 26.5x = 588

-8x = -48

x = 6

sub x=6 into(3)

(3)=> y = 24 - 6

= 18

newspaper = x

= 6

social media = y

= 18

f(x) = 3x2 - 2x g(x) = x + 4 When finding f(x) · g(x), what could the first step look like? A) 3x2 + 12x2 - 2x2 - 8x B) 3x2 + 7x

Anna71 [15]

(3x^2 - 2x)(x + 4)

First step would be: distributive property.

3x^3 + 12x^2 - 2x^2 - 8x

Combine like terms.

3x^3 + 10x^2 - 8x is the simplified form of the functions multiplied.

Your answer is D.

Interpret the slope based on the chart.

bogdanovich [222]

Answer:

b. For 100 additional burglaries in California one expects to see an increase of about 3 burglaries in Hawaii.

Step-by-step explanation:

The slope gives the increase in the independent variable per unit increase in the dependent variable. Hence, a reasonable interpretation for the slope would be ;

the rate of change in the number of burglaries in Hawaii per 100 unit change in number of burglaries in California is 3.

Hence, for 100 additional burglaries in California, the rate of change in the number of burglaries in Hawaii is 3.
