1/2 because you have to add 2+2 = 4 and then put that over 5+3 = 8 which is 4/8 simplyfied as 1/2 or 1:2

pizza palace cuts a medium pizza into 8 slices.the same size pizza at pizza pioneers si cut into 16 slices.Jasmine ate 4 slices of a medium pizza from pizza pioneers.what fraction of the pizza from pizza palace is equal to 4/16. Explain

Answers

Answer:

$(1)/(4)$

Step-by-step explanation:

Given,

Pizza palace cuts a medium pizza into 8 slices,

So, the part of each slice in Pizza palace = $(1)/(8)$

Let x be the number of slice eaten from Pizza palace,

Such that it is equal to $(4)/(16)$ part of the pizza,

$(1)/(8)* x = (4)/(16)$

$(x)/(8)=(4)/(16)$

$16x = 32$

$\implies x = 2$

Hence, $(1)/(4)$ of the pizza from pizza palace is equal to 4/16.

It would be half of the pizza from Pizza Pioneers because 16 is 8 doubled. Therefore, two pieces of pizza from Pizza Palace is equal to 4 pieces from Pizza Pioneers.

Three people are kayaking. They all started at the same point and rowed in the same direction for 20 minutes. Laura rowed 7/8 mile
Daniel rowed 1/2 mile
Annabelle rowed 1/4 mile
Part A:
Did Laura row a distance greater than, less than, or equal to the combined distance of Daniel and Annabelle?

Answers

Answer:

Greater than

Step-by-step explanation:

In order to compare the distances rowed, we need to come up with a common denominator. Our least common denominator is 8 because 2 and 4 are both divisors of 8.

Laura rowed 7/8 mile

Daniel rowed 4/8 mile ( $(1)/(2)* 4$ )

Annabelle rowed 2/8 mile ( $(1)/(4)*2$ )

Daniel and Annabelle rowed a combined 6/8 mile ( $(4)/(8) +(2)/(8)$ ). 7/8 is greater than 6/8. Laura rowed a distance greater than the combined distance of Daniel and Annabelle.

Find the students error in solving the following inequality 2<-3x-4<56<-3x<5
-2>x>-5/3

Answers

Answer:

The student did not add 4 to all sides of the inequality

Step-by-step explanation:

2<-3x - 4<5

Add 4 to all sides

4 + 2< -3x - 4 + 4 < 5 + 4

6< -3x < 9

Divide all sides by the coefficient of x; -3

-2< x < -3

Remember, when dividing an inequality with a negative number, you must flip the sign

So, this becomes;

-2 > x > -3

A telephone company charges a fixed monthly rate plus a rate per minute of usage. The company charges $135 for 100 minutes of usage and $375 for 500 minutes of usage. An equation can be written to show the relationship between the total minutes used (x) and the total monthly charges (y). Which of the following best describes the steps to draw the graph of y against x? Draw a graph which joins the points (135, 100) and (375, 500) and has a slope = 0.6 Draw a graph which joins the points (100, 135) and (500, 375) and has a slope = 0.6 Draw a graph which joins the points (100, 135) and (500, 375) and has a slope = 1.67 Draw a graph which joins the points (135, 100) and (375, 500) and has a slope = 1.67

Answers

Answer:

The graph which describes the relationship between company charges and minutes of usage is the graph containing the points (100,135) and (500,375) and has a slope of 0.6. Where the first coordinate of the points are the minutes and the second coordinate the charges.

Step-by-step explanation:

As the first coordinate of a point always represents the x variable and the second coordinate they value, the possible options to describes this situation are:

The graph join which joins the points (100,135) and (500,375) and has a slope =0.6

The graph join which joins the points (100,135) and (500,375) and has a slope =1.6

The other options are not possible since the order of the coordinates is inverted.

One of the possibilities showing above must be rejected since one have the incorrect slope. To verify the correct slope we calculate the variation of y coordinates and divide by the variation of x coordinates:

$m=((y2-y1))/((x2-x1))$

Assuming the point named '2' as the point (100,135) and the point named '1' as (500,375):

$m=((375-135) \$)/((500-100) minutes)$

$m=((240) \$)/((400) minutes)$

$m=0.6 \$/minutes$

Thus, that the graph joining the points (100,135) and (500,375) and has a slope of 0.6 the only possible action.

The correct answer to this question is letter "B. Draw a graph which joins the points (100, 135) and (500, 375) and has a slope = 0.6." The one on the x axis should be the number of minutes and on the other hand, the one on the y axis should be the amount being charged.
