Sheila has 11 1/2 pounds of potato salad. She wants to divide the potato salad into containers, each of which holds 1 3/4 pounds

Mice21 [21]

Hello!

<h2>Answer:</h2>

$\boxed{ \bf Sheila~will~need~about~7~containers.}$

__________________________________________________

<h2>Explanation:</h2>

First, we will need to convert the mixed fractions to improper fractions.

Numerators: (2 · 11) + 1 = 23

(4 · 1) + 3 = 7

Denominators: stay the same.

11 $\frac{1}{2}$ ⇒ $\frac{23}{2}$

1 $\frac{3}{4}$ ⇒ $\frac{7}{4}$

Next, we must divide these two fractions:

$\frac{23}{2}$ ÷ $\frac{7}{4}$

We must flip the divisor into a reciprocal:

$\frac{23}{2}$ ÷ $\frac{4}{7}$

Change the division sign to multiplication and multiply:

$\frac{23}{2}$ × $\frac{4}{7}$ = $\frac{92}{14}$

To find out how many containers will be needed, simply convert this fraction to a decimal by dividing the numerator by the denominator.

92 ÷ 14 = 7 (Rounded)

The sum of 3 consecutive even numbers is 60. What are they?

ASHA 777 [7]

Answer:

18, 20 and 22.

Step-by-step explanation:

Let the lowest number be n, then:

n + n + 2 + n + 4 = 60

3n + 6 = 60

3n = 54

n = 18.

So the other 2 are 20 and 22.

Supppose a rectangle will undergo a rotation about the origin of a coordinate plane and a translation of 6 units down. Which of

Nitella [24]

Options:

The resulting rectangle will be congruent to the original rectangle regardless of the order of the rotation and the translation.

The resulting rectangle will be congruent to the original rectangle only if the rotation occurs before the translation.

The resulting rectangle will be congruent to the original rectangle only if the translation occurs before the rotation.

The resulting rectangle will not be congruent to the original rectangle regardless of the order of the rotation and the translation.

Answer:

The resulting rectangle will be congruent to the original rectangle regardless of the order of the rotation and the translation.

Step-by-step explanation:

<em>See attachment for options</em>

Given

Shape: Rectangle

Transformation

- Rotation

- Translation 6 units down

Required

True statement about the transformation

From the options, we understand that we are to answer the question based on whether or not the image of the transformation will equal the original.

The given transformations are rigid transformations and as such, they do not in any way change the measure of the length and/or angle of the new image, after transformation

So, irrespective of which transformation comes first, both shapes will be congruent.

Hence: (a) is true
