Answer:

a. $\frac{3}{4}$ teaspoons

Step-by-step explanation:

You didn't show in the image that each batch makes 12 cupcakes, but I remember that from the other problems of yours that I helped with.

We know that each batch is 12 cupcakes and we want 36 cupcakes. This means that we will have to triple the recipe.

This means that we can triple the value of baking powder which is $\frac{1}{4}$ tsp

$\frac{1}{4} *3=\frac{3}{4}$

Julian calculates the volume of a rectangular prism with the dimensions 3/4ft by 4 feet by 1/2 ft. His work is shown here.

lbvjy [14]

Answer:

He multiplied the denominators incorrectly

Step-by-step explanation:

we know that

The volume of a rectangular prism is given by the formula

V=LWH

we have

L=3/4 ft

W=5/1 ft

H=1/2

substitute

V=(3/4)(5/1)(1/2)= 3x5x1= 15

₋₋₋₋₋₋₋₋ ₋₋₋₋ ft³

4x1x2= 8

therefore

He multiplied the denominators incorrectly

The slope of the line below is -2. Use the coordinates of the labeled point to

Vilka [71]

Answer:

We can express the equation for any linear equation with slope -2 and point (x0,y0) as:

$y=-2x+(y_0+2x_0)\\\\y-y_0=-2(x-x_0)$

Step-by-step explanation:

Incomplete question:

There is no point to complete the equation.

As we have no point to complete the linear equation, we will solve for any given point (x0,y0) and a slope of m=-2.

The linear equation can be written generically as:

$y(x)=mx+b\\\\y(x)=-2x+b$

If a point, like (x0,y0) belongs to the linear equation, it satisfies its equation. Then:

$y_0=-2x_0+b$

Then, we can calculate b as:

$y_0=-2x_0+b\\\\b=y_0+2x_0$

We can express the equation for any linear equation with slope -2 and point (x0,y0) as:

$y=-2x+(y_0+2x_0)\\\\y-y_0=-2(x-x_0)$

Fill in the blanks to make true number sentences.<br><br> 1 3/5 = __ : __

arsen [322]

Answer:

1 6/10

Step-by-step explanation:

you should first turn this fraction into a improper fraction

1 3/5= 8/5

now you multiply the denominator and the numerator by the same number, in this case i am using 2

8/5 times 2/2= 16/10 or 1 6/10

What is the area of this figure?

insens350 [35]

Answer:

54 units squared

Step-by-step explanation:

You have to divide the shape into simpler shapes such as rectangles and triangles that you can easily find the area of. Then, add those areas together. I divided it into one rectangle and three triangles.

Rectangle 1: length=7 width=6 6(7)=42

Triangle 1: base=6 height=2 1/2(6)2=6

Triangle 2: base=3 height=2 1/2(3)2=3

Triangle 3: base=6 height=1 1/2(6)1=3

Area= R1+T1+T2+T3= 42+6+3+3= 54 units squared

Find the product of (3x-4)(2x^2+2x-1)

lapo4ka [179]

Answer:

6x^3 - 2x^2 -11x +4

Step-by-step explanation:

(3x-4)(2x^2+2x-1)

Multiply 3x by the second term

3x* (2x^2+2x-1)

6x^3 +6x^2 -3x

Multiply -4 by the second term

-4*(2x^2+2x-1)

-8x^2 -8x+4

Add these together, lining up the terms

6x^3 +6x^2 -3x

-8x^2 -8x+4

----------------------------------

6x^3 - 2x^2 -11x +4
