Mariulka [41]3 years ago

5 0

Answer:

Okays so for 100 guests we can make the equation $5000 ÷ 100 = $50.00

For 100 guests at the wedding it would cost <u>$50.00</u> per plate

For 45 guests we can make the equation $2750 ÷ 45 = $61.111111111111, it would be a repeating decimal

For 45 guests at the wedding, it would cost <u>$61.111111111111</u>

I hope that this can help you! ^‿^

What is the 101st term for the sequence 13, 9, 5, 1... ?

NeX [460]

Step-by-step explanation:

a=13
d=13-9=4

${:}\longrightarrow$ $\sf S_n={\dfrac {n}{2}}\left [2a-(a-1)d\right]$

${:}\longrightarrow$ $\sf S_101={\dfrac {101}{2}}\left [26 (12)4\right]$

${:}\longrightarrow$ $\sf 50.5×1248$

${:}\longrightarrow$ $\sf S_101=63504$

${:}\longrightarrow$ $\sf a_n=a+(n-1)d$

${:}\longrightarrow$ $\sf a_101=13+(101-1)-4$

${:}\longrightarrow$ $\sf a_101=13+100(-4)$

${:}\longrightarrow$ $\sf 13-400$

${:}\longrightarrow$ $\sf a_101=-387$

Find the missing side length

sasho [114]

Answer:

Missing side length = 54

Step-by-step explanation:

If both the triangles given in the picture are similar their corresponding sides will be proportional.

By applying this rule in the given similar triangles,

$\frac{35}{30}=\frac{49}{42}=\frac{63}{6x-6}$

$\frac{7}{6}=\frac{7}{6}= \frac{63}{6x-6}$

$\frac{7}{6}= \frac{63}{6x-6}$

$\frac{1}{6}= \frac{9}{6x-6}$

$\frac{1}{6}= \frac{9}{6(x-1)}$

$1=\frac{9}{x-1}$

$x-1=9$

$x=10$

Therefore, missing side length = $6x-6$

= $6(x-1)$

= $6(10-1)$

= $6\times 9$

= $54$

3/2+(-6/5) what does this equal? Please help

34kurt

Answer:

3/10

Step-by-step explanation:

The first thing that you need to do is to find the common denominator of the two fractions. The least common multiple of 2 and 5 is 10, so we can express the new equation as 15/10-12/10=3/10. Hope this helps!
