Answer: The student councils savings change by $41.

Step-by-step explanation:

Number of backpacks = 4

Cost of each backpack = $9

Paper and pen costs = $5

Total spending = (Number of backpacks ) x (Cost of each backpack ) + (Cost of paper and pen)

= $ (4 x 9 +5)

= $ 41

Hence, the student councils savings change by $41.

C. A parallelogram
Oxana [17]

If a parallelogram has an area of 7 square units, and the height corresponding to a base is (\frac{1}{4}) units, then the base is 28 units.

As per the question statement, a parallelogram has an area of 7 square units, and the height corresponding to a base is (\frac{1}{4}) units.

We are required to find out the base of the parallelogram.

To solve this question, we need to know the formula to calculate the area of a parallelogram, which goes as

Area of Parallelogram = (Base * Height)

Putting our data obtain from the question statement, in the above-mentioned formula, we can calculate the value of the base of our concerned parallelogram, i.e.,

7=(base*\frac{1}{4})\\or, base=(7*4)\\or, base = 28
Therefore, base of our concerned parallelogram is 28 units.

  • Parallelogram: In Euclidean geometry, a parallelogram is a four-sided, plane, closed figure (Quadrilateral) with two pairs of parallel, opposite sides.

daser333 [38]
On the number line, the distance between negative 11 and positive 7 is <em>18 units</em>.

Choice A:  The absolute value of (-11 - 7) = absolute value of (-18) = 18.

Choice C:  The absolute value of [ 7 - (-11) ] = absolute value of (7+11) = 18.

'A' and 'C' are both the same number, and it's the correct answer to the question.
