Answer: D. 7 divided by 4

Step-by-step explanation:

Hi, the options are:

<em>A.4/7  </em>

<em>B. 1/7 of 4  </em>

<em>C. 4 divided by 7  </em>

<em>D. 7 divided by 4 </em>

So, to answer this we simply have to divide the number of yards (4) by the number of sections (7).

Mathematically speaking:

4 yards /7 sections = 7/4 = 0.57 yards of fabric per section.

So, options A and C are equal to the expression we deducted.

B is also correct. Because 1/7 x 4 = 0.57

So, the expression that does not give the amount of fabric each section will have is option D =7 divided by 4

Answer:

See below.

Step-by-step explanation:

To find the amount in each section, divide the number of yards by the number of sections.

4/7 is the 4/7 yards per 1 section.

4/7 = 0.57 yards per 1 section.

etc.

Choose the option which DOES not represent these values.

<h3>Answer:</h3>

761680

<h3>Explanation:</h3>

\sf \boxed{\sum _{n=1}^{44}\:60\left(1.2\right)^{n-2}}

<u>Identify the following's</u>:

First Term [a]  =  60(1.2)ⁿ⁻² = 60(1.2)¹⁻² = 50

Common ratio [r]  =  1.2

Total Terms [n] =  44

===========================

\sf Geometric \ Sum \ of  \ Terms = \dfrac{a(r^n - 1)}{r-1}

===========================

Solving Steps:

<em />\rightarrow \sf \dfrac{a(r^n - 1)}{r-1}<em />

<em />

<em />\rightarrow \sf \dfrac{50(1.2^{44} - 1)}{1.2-1}<em />

<em />

<em />\rightarrow \sf 761679.5808<em />

<em />

\rightarrow \sf 761680 \ \ \  (rounded \ to \ nearest \ integer)

Identify the transformation that maps the figure onto itself <br><br> Please help
Lapatulllka [165]

Answer:

  B.  Rotate 180° clockwise around (8, 4) and reflect across the line x=8.

Step-by-step explanation:

The figure is symmetrical (order 2) about the point (8, 4), and about the lines x=8 and y=4.

Hence, rotation 180° about the point (8, 4) makes the figure look unchanged. Since the figure is also symmetrical about the line x=8, reflecting it across that line will also leave the figure unchanged.

__

Any of the other transformations have the effect of translating the figure somewhere else.
