Answer:

A.) 7

Step-by-step explanation:

If we know that angle 6 = angle x - 3 , and angle 12 = angle x + 1, and that 12 is twice as much as six. We can conclude 7 has the be the answer because that would make x - 3 = 4 if x = 7 and x + 1 = 8 if x = 7 as well. That would fit the criteria that angle 8 is also twice as much as 4, so 7 should be the answer !

For the arithmetic sequence 42, 32, 22, 12... find the 18th term.

Stella [2.4K]

Answer:

The18th term of the given sequence is -128

Explanation:

To find the 18th term of the sequence:

42, 32, 22, 12, ..., we need to find the nth term of the sequence first.

The nth term of a sequence is given be the formula:

$T_n=a+(n-1)d$

Where a is the first term, and d is the common difference.

Here, a = 42, d = 32 - 42 = -10

$\begin{gathered} T_n=42+(n-1)(-10) \\ =42-10n+10 \\ T_n=52-10n \end{gathered}$

To find the 18th terem, substitute n = 18 into the nth term

$\begin{gathered} T_{18}=52-10(18) \\ =52-180 \\ =-128 \end{gathered}$

Can someone help me with this?

aivan3 [116]

Step-by-step explanation:

The formula for the volume of a sphere is V = 4/3 πr³.

Given

Volume (v) = 57ft³

$v = \frac{4}{3} \pi {r}^{3}$

$57 = \frac{4}{3} \times 3.14 \times {r}^{3}$

$57 = \frac{12.56}{3} \times {r}^{3}$

$57 = 4.19 \times {r}^{3}$

${r}^{3} = \frac{57}{4.19}$

${r}^{3} = 13.6$

$r = \sqrt[3]{13.6}$

Therefore r = 2.4 ft

I gave my answers by rounding off. so if you don't round off then it's answer is 2.3 ft

Explain and show your work, please.

ArbitrLikvidat [17]

It is given that aiden has purchased a 2 lb package, a 3 lb package, and a 4 lb package
The first step is to add these packages together
2+3+4 is 9
each turkey burger needs 1/3 lb of turkey, which also means that every pound of turkey aiden has can make 3 turkey burgers

Aiden has 9 pounds of turkey, so he can make 27 turkey burgers (3*9)

Hope this helped! If you still need help I can answer in comments

docker41 [41]

Answer:

y = 3/4x - 8/3

Step-by-step explanation:

y = 3/4x + b

1/3 = 3/4(4) + b

1/3 = 3 + b

-8/3 = b
