Hey there! I'm happy to help!
We want to put this 0.002 into scientific notation, where you put it as a one digit number multiplied by 10 raised to a certain power.
If we move the decimal to the right 3 times, we will have 2. We will multiply this 2 by to show that it is still equal to 0.002.
So, the mass of the mustard seed is 2×.
Now, we multiply this mustard seed mass by the number of mustard seeds to find the weight of all of the mustard seeds combined.
(2×)×(4.3602×)
Let's round 4.3602 to the nearest whole number, which is 4. We multiply those two together.
2×4=8
And we multiply the two exponents. When multiplying them, you add the numbers in the exponent. -3 and 4 combined gives us 1, and 10 the first power is just 10.
So, a good estimate for the mass of the mustard seeds is 80 grams, which is the same as (2×)×(4×)=8×
Have a wonderful day! :D
A = 3.125
Sorry I only know A.
You would divide 500 by 160.
Answer: ∠DOB: 48°
Step-by-step explanation:
1. we need an equation first. the sum of all angles (108°, n°, 2n°) is equal to 180°. we can depict this with the equation: 108°+2n°+n°=180°
2. now we can solve for the missing variable, n.
108°+3n°=180° → subtract both sides by → 3n°=72° → divide both sides by 3 → n=24°
3. now that we know that n=24°, we can solve the value of ∠DOB. we can see that ∠DOB is 2n° which we just plug the number we got for n into the equation. 2*24=48° meaning ∠DOB is 48°
hope this heped! ♡
Answer:
1 unit
Step-by-step explanation:
We have the following formula to find the length of an arc that subtends an angle of radians is:
S = rΘ where:
- r is the radius
- Θ is the subtended central angle given in radians
Given the information in this question, we have:
=> the length of an arc in this question is:
1*1 = 1 unit
Hope it will find you well
Answer:
-5
Step-by-step explanation:
Let x be the number.
4*(x-3)=3+4x+3x
4x-12=3+4x+3x
-12-3=3x
-15=3x
x=-5
