Jillian is using integer tiles to add 7 + (negative 2). She uses the steps below. Step 1 7 positive tiles. Step 2 7 positive tiles and 2 negative tiles. Step 3 7 positive tiles and 2 negative tiles. 2 positive and 2 negative tiles are circled. Step 4 7 + (negative 2) = 2 Jillian has made an error. In which step does it occur? Step 1 Step 2 Step 3 Step 4 Mark this and return

Answers

Answer 1

Answer:

Step 4

Step-by-step explanation:

Given the expression 7+(-2)

Let 7 be 7 positive tiles since it is a positive number

Let -2 be 2 negative tiles being a negative number

7+(-2) = 7 positive tiles and 2 negative tiles

note that + * - will give minus sigh (-), the expression will become:

7+(-2) = 7-2

7-2 = 5

Hence the expression gives 5 positive tiles not 2 positive tiles according to Jillian calculations in step 4.

Hence Jillian made an error in step 4

What’s the y-intercept of the line graphed on the grid?

Answers

Answer:

y-intercept is 4.5

Step-by-step explanation:That is when the line intersects the y-axis

Answer:

y intercept = 5.5

Step-by-step explanation:

The y-axis is the vertical (up and down) line in the center of the graph. When the line passes over it, wherever it passes, will be your y intercept.

In this situation it passes in the middle of 5 and 6 so it would be 5.5.

Una tableta contiene 500 mg de paracetamol, ¿cuántas tabletas se obtendrán con 5kg del mismo medicamento? xfavor ayudenme con explicación y todo lo necesito para el sabado

Answers

Answer:

Se pueden obtener 10.000 comprimidos de 500 mg de paracetamol a partir de la cantidad de 5 kg del medicamento

Step-by-step explanation:

La cantidad en masa de paracetamol en una tableta = 500 mg de paracetamol / tableta

El número de comprimidos que contienen 500 mg de paracetamol que se pueden obtener a partir de 5 kg del medicamento (paracetamol) se calcula dividiendo los 5 kg del medicamento por los 500 mg de paracetamol / comprimido de la siguiente manera;

[tex]El \ nmero \ de \ tableta = \dfrac{5 \ kg \ paracetamol}{500 \ mg \ paracetamol/tableta }[/tex]

Observamos que 5 kg = 5,000,000 mg

Por lo tanto;

[tex]El \ numero \ de \ tableta = \dfrac{5,000,000 \ mg \ paracetamol}{500 \ mg \ paracetamol/tableta } = 10,000 \ tabletas[/tex]

Por tanto, podemos obtener 10.000 comprimidos de 500 mg de paracetamol a partir de la cantidad dada de 5 kg del medicamento.

A cookie recipe calls for ¾ cups of sugar. The recipe makes 20 cookies. How much sugar is required to make 80 cookies

Answers

Answer:

So based on the given problem above, it says that, for one batch with 3/4 cup of brown sugar can make 6 dozen big cookies. If we are to make 15 dozen cookies, what we need to do is to divide 3/4 cup of brown sugar by 6 dozen, and we get 0.125. This means that per dozen, it is equivalent to 0.125 cup of brown sugar. If we multiply it by 15 dozens, we get 1.875 cup or 1 and 7/8 cup of brown sugar.

Answer:

3 cups of sugar.

Step-by-step explanation:

80/20 = 4 batches

3/4 cups x 4 = 3 cups of sugar
