Answer:

i think 7

Step-by-step explanation:

Option B: SEVEN

The number that goes not belong in the following series is SEVEN

Given :

The numbers in the series is

2 - 5 - 7 - 14 - 41 - 122 - 365 - 1094 - 3281

First number is 2

[tex]2 \cdot 3 -1=5\\[/tex]

Lets multiply the previous term by 3  and subtract 1 to check the other terms

[tex]5 \cdot 3 -1= 14\\14 \cdot 3 -1= 41\\41 \cdot 3 -1= 122\\122 \cdot 3 -1= 365\\365 \cdot 3 -1= 1094\\1094 \cdot 3 -1= 3281\\[/tex]

From the series we can see that 7 does not belong to the series .

So,  SEVEN does not belong to the series .

Step-by-step explanation:

Answer:

45 degrees

Step-by-step explanation:

42 degrees is 42 “points” away from zero (picture a number line). -3 degrees is 3 points away from zero on the number line, but in the opposite direction. The two numbers are 45 “points” away from each other.

When they say find the difference, it’s a subtraction equation.

42 - (-3) = 42 + 3 = 45

Answer:

The length can be 5 and the width 10.

Step-by-step explanation:

perimeter is equal to 2L + 2W

area is equal to L * W

you get 2 equations:

30 = 2L + 2W

50 = L*W

we'll solve by substitution.

you can use either equation to solve for either variable.

we'll use the second equation to solve for L.

second equation is:

50 = L*W

divide both sides of this equation by W to get:

L = 50/W

we now have a value of L that we can substitute in the first equation which we can then use to solve for W.

the first equation is:

30 = 2L + 2W

replace L with 50/W to get:

30 = 2*(50/W) + 2W

simplify to get:

30 = 100/W + 2W

multiply both sides of this equation by W to get:

30W = 100 + 2W^2

subtract 30W from both sides of this equation to get:

2W^2 - 30W + 100 = 0

factor this equation to get:

(2W - 20) * (W - 5) = 0

solve for W to get:

W = 10 or W = 5

if W = 10, then use the equation of 50 = L*W to get L = 5

if W = 5, then use the equation of 50 = L*W to get L = 10

you have 2 possible solutions.

L = 5 and W = 10 or:

L = 10 and W = 5

both are plausible so we'll test them both out.

when L = 5 and W = 10:

the first equation becomes 2*5 + 2*10 = 10 + 20 = 30

the second equation becomes 5*10 = 50

both equations confirm that the solution of L = 5 and W = 10 is good.

when L = 10 andW = 5:

the first equation becomes 2*10 + 2*5 = 20 + 10 = 30

the second equation becomes 10*5 = 5

both equations confirm that the solution of L = 10 and W = 5 is good.

the ticket can have either:

a length of 5 and a width of 10 or:

a length of 10 and a width of 5.

since the length is usually longer than the width, you are free to choose that the ticket most likely has a length of 10 and a width of 5.

alternatively, you can simply say that the dimensions are 5 by 10 and let the recipient of that information determine which is the length and which is the width.

mathematically, the length can be 10 and the width 5 or the length can be 5 and the width 10.

Answer:

$3.50

Step-by-step explanation:

to find the range you take the highest number and the lowest number and subtract them

so with that, let us do just that-

$5.75, $3.75, $3.25, $2.25

$5.75-$2.25

=$3.5

and since we're dealing with money we must add a '0' to the end of the decimal- $3.50

good luck :)

Answer: hope this helps ♡

Lily had 16 stamps and Mackenzie had 20 stamps.

Step-by-step explanation:

Lily gives 4 stamps to Mackenzie

(Mackenzie)     m + 4 = 2(L - 4)      (Lily)

Solve for Lily:

m + 4 = 2L - 8

m + 4 + 8 = 2L

(m + 12) ÷ 2 = 2L ÷ 2

(m + 12) ÷ 2 = L

L = (m + 12) ÷ 2 (we will substitute this value for L in the second equation)

Mackenzie gives 4 stamps to Lily

(Mackenzie)     m - 4 = L + 4      (Lily)

m - 4 = ((m + 12) ÷ 2) + 4

m × 2 - 4 = ((m + 12) ÷ 2 × 2) + 4

2m - 4 + 4 = (m + 12) + 4 + 4

2m - m = (m - m + 12) + 8

m = 12 + 8

m = 20 (we will substitute this value of m in the next equation)

L = (m + 12) ÷ 2

L = (20 + 12) ÷ 2

L = 32 ÷ 2

L = 16

Answer:

12.56

Step-by-step explanation:

So, the circumference will be 4(3.14), which is 12.56. So, now you can solve for area. By the way, the formula is: C = pi(d) (Just saying)

Anyways, A = pi(r)2. So, with the radius being half of the diameter, you will cut 4 in half. You are now ready to solve.

A = 3.14 (2) (2), which is 12.56 .

Hope this helps! :)
