Lyndsay is baking cookies. If one batch of cookies uses 1/3 cup of sugar, and she has 1/2 cup of sugar in her cupboard, how many batches of cookies can she make? (Note: It's possible to make a fraction of one batch.)

Answers

Answer: 1¹/₂ batches

Step-by-step explanation:

Lyndsay is making cookies and 1/3 cup of sugar can make a batch of cookies.

This means that ratio wise, the following is true:

1 batch        :         1/3 cups of sugar

If she had only 1/2 cups however, the number of batches she could make using direct proportion is:

1          :        1/3

x         :         1/2

1/3x = 1/2

x = 1/2 ÷ 1/3

x = 1/2 * 3/1

x = 3/2

x = 1 1/2 batches

x= 1¹/₂ batches

Help ASAP. This one is also vital to my math grade. I will award 100 points and brainly to whoever can solve this. This is slope intercept form. There is 2 parts to this, will post second part to this when I get the answer for the first part and unlock the second part

Answers

Answer:

Slope: 1

Step-by-step explanation:

(9,0) and (0, -9)

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

m= (-9 - 0)/ (0 - 9)

m= (-9)/(-9)

m = 1

Answer:

Solution given:

coordinates are

(x1,y1)=(9,0)

(x2,y2)=(0,-9)

we have

Slope =[tex] \frac{y2 - y1}{x2 - x1} [/tex]

[tex] = \frac{ - 9 - 0}{0 - 9} [/tex]=1

The slope of a line is 1.

Write the slope-intercept form of the equation of a line with a slope of -5/8 that passes through the point (-14,6)

Answers

Answer:

y = -5/8x - 11/4

Step-by-step explanation:

Since we already know the slope which is -5/8. This will be the m in the equation.

To find the y-intercept, plug the coordinates into the equation, which is

y= -5/8 + b

6 = -5/8(-14) + b

6 = 35/4 + b

= -11/4 = b

Answer:

1) x = 20

2) Try it yourself based on #1

3) D. BE (it a a segment, it is on the hypotenuse, and it is adjacent to AB)

Step-by-step explanation:

I'll do the first one and you can try the second one

1) Since the two triangles are similar, corresponding parts are similar (CPSP - corresponding parts of similar polygons)

2) Since the corresponding sides are similar, [tex]\frac{AX}{AB} = \frac{XY}{BC}[/tex]

3) We know that AX is 12, AB is 20 (AX+XB=12+8 because of pwp -> part whole postulate), XY is 17, and BC is x

4) Substitute these values into the equation from step 2

[tex]\frac{12}{20} = \frac{12}{x}[/tex]

5) Cross-multiply to get 12x = 12(20)

6) Solve

12x = 240

x = 20
