The first sequence rule is add 4 starting from 15. The second sequence rule is add 3 starting from 18. What is the first number

Snezhnost [94]

Answer: 27

Step-by-step explanation:

Given

In the first sequence, the first term is $a_1=15$

Common difference is $d_1=4$

In the second sequence, the first term is $b_1=18$

Common difference is $d_2=3$

The nth term of the sequence is $a_n=a+(n-1)d$

for the same number to appear on both sequence, the nth term must be equal

$\Rightarrow 15+(n-1)4=18+(n-1)3\\\Rightarrow 3=(n-1)\\\Rightarrow n=4$

Put n=4

$\Rightarrow 15+(4-1)4\\\Rightarrow 15+12=27$

Therefore, 27 is the first common term in both sequences.

A large bin of mixed nuts contains peanuts, cashews, almonds, and walnuts. Sheila scoops out a bowl full of nuts and counts how

Diano4ka-milaya [45]

17 + 9 + 12 + 10 = 48 total nuts.....out of those 48, 9 were cashews

9/48 = x / 32....9 cashews to 48 nuts = x cashews to 32 nuts
cross multiply
(48)(x) = (9)(32)
48x = 288
x = 288/48
x = 6.......so there is expected to be 6 cashews out of 32 nuts

Answer:

30°

Step-by-step explanation:

x + 90 = 2 × 60 ( angle at center = 2 × angle at circumference.)

x +90 = 120

x = 120-90

x = 30°
