3. Jordan cooked a 16 1/5 pound turkey in 5 2/5 hours. How many minutes per

s344n2d4d5 [400]

Answer:

20 minutes per pound

Step-by-step explanation:

we know that

To find the unit rate divide the total time by the total weight

Convert mixed number to an improper fraction

$16\frac{1}{5}\ lb=\frac{16*5+1}{5}=\frac{81}{5}\ lb$

$5\frac{2}{5}\ lb=\frac{5*5+2}{5}=\frac{27}{5}\ h$

Convert hours to minutes

$1\ h=60\ min$

$\frac{27}{5}\ h=\frac{27}{5}(60)=324\ min$

Find the unit rate

$\frac{324}{\frac{81}{5}}=\frac{1,620}{81}=20\ \frac{min}{lb}$

therefore

20 minutes per pound

The length of the major axis of the ellipse below is 12. What is the sum of the lengths of the red and blue line segments

just olya [345]

We know that the major axis of the ellipse is 12 ( 2 a = 12 ).An ellipse is a curve with 2 focal points, such that the sum of the distances to the 2 focal points is constant for every point on a curve.If P is a point on a curve:PF 1 + PF 2 = 2 a( Blue line ) + ( Red line ) = 2 a = 12Answer: The sum of the lengths of the red and blue line segments is 12.

10 Points! Drag the tiles to the correct boxes to complete the pairs.

Oksi-84 [34.3K]

<h2>Hello!</h2>

The answers are:

First box: 7 times the cube of the sum of x and 8

Second box: 8 added to the cube of 7x.

Third box: 8 added to 7 and x cubed.

Fourth box: the cube of the sum of 7x and 8.

We are given the expression and we need to macth to the correct verbal description, so we have:

First box:

$7(x+8)x^{3}$

It's 7 times the cube of the sum of x and 8

Second box:

$(7x)^{3}+8$

We have that "7x" is cubed and then, added to 8, so, it's 8 added to the cube of 7x.

Third box:

$7x^{3}+8$

We have "7" times "x" cubed and added to 8, so it's 8 added to 7 and x cubed.

Fourth box:

$(7x+8)x^{3}$

We have "7x" added to 8, and the expression is cubed, so, it's the cube of the sum of 7x and 8.

Have a nice day!

Rafeal wants to know if there is a single transformation that will move trapezoid JKLM onto trapezoid PQRS Below

aliina [53]

A. A 90° counterclockwise rotation of trapezoid JKLM about the origin will move angle L onto angle R.

Step-by-step explanation:

Since both the trapezoids, trapezoid JKLM and PQRS are congruent, we can do any transformation, may be rotation, reflection and translation.

A 90° counterclockwise rotation of trapezoid JKLM about the origin will move angle L onto angle R is the true statement others are incorrect statements.

When the Preimage is rotated 90° counterclockwise rotation, then its coordinates (x,y) changed into (-y,x)
