Mathematics

4 0

Ummmm that’s a triangle but I guess I’ll solve for both 7x7= 49/2= 24.5 triangle. Polygon is different but I guess if the perimeter and line to the center is both 7 okay 7x5= 35x7= 245/2= 122.5 cause triangle is wxL /2 and polygon is AxP/2 soooo I hope this helped

What is the 8th term of the geometric sequence 8,16,32
ratelena [41]

the 8th term of the geometric sequence 8, 16, 32 is 1024

<h2>Explanation</h2>

<u>we know that</u>

geometric sequence 8, 16, 32

<u>the </u><u>question</u><u> </u><u>is</u>

the 8th term

<u>the </u><u>answer </u><u>is</u>

first we have to find the ratio

\sf r=  \frac{ U_2}{U_1}  \\  \sf r=  \frac{ 16}{8} \\  \sf r = 2

than, we have to find the 8th term

\sf U_n = ar^{n-1} \\ \sf U_8 = 8 \times 2^{8-1} \\ \sf U_8 = 8 \times 2^7 \\ \sf U_8 = 8 \times 128 \\ \bold {\sf U_8 = 1024}

Someone please help me on this I'm unsure if my answer is correct
mafiozo [28]

Answer:

A. length = 23 cm; width = 5 cm

Step-by-step explanation:

So if 4 times the width would be 4w and 3 more than would be + 3, the equation would be l = 4w + 3. If the perimeter is 56, then the new equation, 2(4w + 3) + 2(w) = 56 can be formed. This simplifies to 8w + 6 + 2w = 56, then to 10w + 6 = 56, then to 10w = 50, and finally, w = 5. So the width is 5, and now plug it into the first equation.

l = 4(5) + 3, becomes l = 20 + 3, becomes l = 23.

So the dimensions are: length = 23 cm, width = 5 cm.

*And just to be sure, 2(23 + 5) = 2(28) = 56 which is correct.

Last year, Mr. Engle's total income was $52,000, while his total expenses were $53,800. Use the expression I-E/12, where I repre
olga55 [171]
Given Mr. Engle’s total income, I = $52,000 and total expenses, E = $53,800, solving for average difference between income and expenses per month:
(I-E)/12 = ($52,000 - $53,800)/12
(I-E)/12 = - $1,800/12
(I-E)/12 = -$150
This means that Mr. Engle’s expenses exceed his income by an average of $150 each month in the said year.
