The length of 83,800,000 in scientific notation is 8.38 x 10^7
Answer: 838 x 10^5
Step-by-step explanation: We first have to focus on the Zambezi which is 83,800,000 there are 5 zeros, but we have three options 8.38 x 10^7, 83.8 x 10^6, and finally 838 x 10^5, but scientific notation includes no decimals so it is 838 x 10^5.

A board, 28 cm long is cut into three pieces such that the second piece is twice as long as the first and the third is 3 cm longer than the second. Find the length of the shorter piece.
Answers
Answer:
I found the answer, sorry for the last answer it mustve thrown you off, and I know its late but here we go. So its 5cm because 5cm is one piece, if we double that it is 10cm, this is our second piece. It states that the third piece is 3cm longer than the second, which would be 13cm. So 13cm+10cm+5cm is 28cm, the length of the original board
hope i helped this time
x + y + z = 52
such that the second piece is twice as long as the first
y = 2x
third is 7 cm longer than the second
z = y + 7
So,
z = 2x + 7
x + 2x + 2x + 7 = 52
5x = 45
x = 9
y = 18
z = 25. I think
Divide. Write your answer in simplest form. -5/3 divided by (-1/8)
Answers
Answer:
13 1/3 or 40/3
Step-by-step explanation:
KCF
Keep -5/3 how it is
Change the division sign to a multiply sign
Flip -1/8, meaning make it the reciprocal (-8/1)
Then multiply across, getting 40/3
Lastly, you can change it to mixed for or leave it how it is, depending on the directions.
Dividing two negatives equals a positive:
To divide by a fraction, multiply by the reciprocal of that fraction
Calculate the product
40/3=13 1/3
Convert the improper fraction into a mixed number

Sid has a baseball cap collection. 65% of his caps have sports team symbols. If 26 of the caps have the team symbols, how many total caps does Sid have?
39

Answers
B. 40
As we know Sid has 26 Caps
we also know that 26 is 65% of total
so let total caps = x
to calculate x
we know that percent = (Values*100)/total Values.......... i
and here Value = 26 caps
percentage = 65
So we have
65 = (26*100)/x---------------- (As we know that per = fraction*100)..... from i
65x= 2600x = 2600/65x=40 capsHence Answer is 40

⇒ ∠1 and ∠2 are angles lying on a straight line.
⇒This simply means that the sum of ∠1 and ∠2 since the straight line forms an angle of 180°
∠1+∠2=180°
⇒It is given that the measure of ∠2 is 60° more than ∠1
This means that to get ∠2 you have to add 60° in ∠1
As a conclusion we can say that ∠2=∠1+60°...(second equation to get ∠2)
⇒In the equation ∠1 +∠2=180°
⇒Substitute the value of ∠2 which is (∠1+60°)
∠1+(∠1+60°)=180°
⇒Now simplify to get the value of∠1
∠1+∠1=180°-60°
2(∠1)=120°
Note I got 2(∠1) since ∠1+∠1= 2× (∠1)
\(2( < 1)=120\\\frac{2( < 1)}{2} =\frac{120}{2} \\ < 1=60\)
∠1 =60°
⇒Note from what we have now we can also get the value of∠2 but we were not asked to get it. Therefore we will not.

If there is a common difference between consecutive terms then relationship is linear.
A 7, 12, 18
12 - 7 = 5 and 18 - 12 = 6 ← not common so not linear
B 8, 16, 24
16 - 8 = 8 and 24 - 16 = 8 ← common then linear
C 5, 7, 10
7 - 5 = 2 and 10 - 7 = 3 ← not common so not linear
D 4, 16, 30
16 - 4 = 12 and 30 - 16 = 14 ← not common so not linear
Thus table B represents a linear relationship
Allison rolls a standard number cube 30 times and records her results. The number of times she rolled a 4 is 6. What is the experimental probability of rolling a 4? What is the experimental probability of not rolling a 4?
Answers
Step-by-step explanation:
Experimental prob is what happened : four was rolled 6 out of 30 rolls
= 6/ 30 = 1/5
the rest of the time ( 24 rolls) it was NOT a 4 = 24/30 = 4/5
6/30 rolls were 4 which multiplied by 100 gives you a percentage of 20 and then the same thing was used to find 24/30 being 80%
