The product 68 × 43 can be written as the sum ...

... 68 × 43 = 60×40 + 60×3 + 8×40 + 8×3

Of these four partial products, only two are listed in your list of answer choices:

... B. 8 × 3 = 24

... C. 8 × 40 = 320

Quadrilateral A has side lengths 2,3,5 and 6. Quadrilateral B has side lengths 4,5, 8 and 10. Could one of the quadrilaterals be
Makovka662 [10]

Answer:

No

Step-by-step explanation:

Given

Quadrilateral A: 2,3,5 and 6

Quadrilateral B: 4,5, 8 and 10

Required

Determine if one is a scale of another

To do that, we have to divide the corresponding lengths to give ratio.

Considering Side of A = 2 and Side of B = 4

Ratio = \frac{B}{A}

Ratio = \frac{4}{2}

Ratio = 2

Considering Side of A = 3 and Side of B = 5

Ratio = \frac{B}{A}

Ratio = \frac{5}{3}

Ratio = 1.67

There's no need to check further, since the two ratios calculated so far do not have the same value;

<em>Hence, one quadrilateral is not a scale of the other</em>

Find the 11th partial sum of the summation of negative 7i plus 22, from i equals 1 to infinity.
marta [7]
I think you mean,

\sum_{i=1}^{\infty}(7i+22)

You can use the usual formula,

S_{k}=\frac{k}{2}(a_1+a_k)

That in this case is,

S_{11}=\frac{11}{2}(29+99)=704

Where I have used,

a_k=7\cdot k +22
