Answer: First option.
Step-by-step explanation:
You can use the inverse tangent function to find the value of the angle T:
![\alpha=arctan(\frac{opposite}{adjacent})](https://tex.z-dn.net/?f=%5Calpha%3Darctan%28%5Cfrac%7Bopposite%7D%7Badjacent%7D%29)
You can identify in the figure that:
![\alpha=T\\opposite=RG=8\\adjacent=TR=15](https://tex.z-dn.net/?f=%5Calpha%3DT%5C%5Copposite%3DRG%3D8%5C%5Cadjacent%3DTR%3D15)
Then, knowing these values, you can substitute them into
.
Therefore, you get that the value of the angle T rounded to the nearest degree is:
![T=arctan(\frac{8}{15})\\\\T=28\°](https://tex.z-dn.net/?f=T%3Darctan%28%5Cfrac%7B8%7D%7B15%7D%29%5C%5C%5C%5CT%3D28%5C%C2%B0)
This matches with the first option.
The answer is c. 46<span>
In a human diploid somatic cell (2n), there are 22 chromosomes present in two copies and 1 pair of sex chromosomes. This means there are 23 pairs of chromosomes - 22 pairs of autosomes and 1 pair of sex chromosomes. There are in total 46 chromosomes (23 pairs in 2 copies: 23 </span>× 2 = 46<span>).</span>
Answer
$212
Step-by-step explanation:
to get this answer, you must find what 6% of 200 is, which can be calculated using this little equation here
percentage/100 x original price = sales tax
6/100 x 200= 0.06 x 200= 12
this gives you the sales tax, or the amount of money that was added onto the original price, all that's left to do is to add, so original price + sales tax
200+12= $212
Step-by-step explanation:
Start by creating expressions
t= A tray of tomato plants
3t = $16.47
Solve the equation above
3t/3= 16.47/3
t= 5.49
A tray of tomato plants costs $5.47
Now create the ratios
b= A tray of basil plants
t:b = 3:2
Substitute t
5.49:b = 3:2
Rewrite as fractions
= ![\frac{3}{2}](https://tex.z-dn.net/?f=%5Cfrac%7B3%7D%7B2%7D)
Cross multiply
5.49(2) = 3(b)
10.98 = 3b
10.98/3 = 3b/3
3.66 = b
A tray of basil plants costs $3.66
In total she bought 3 trays of tomato plants, which cost $16.47, and 10 trays of basil plants
T0 find out the cost of the 10 basil plants, multiply 3.66 by 10
3.66 × 10 = 36.6
She bought 10 trays of basil plants for $36.60 and 3 trays of tomato plants for $16.47
Add the 2 values together
36.60+16.47 = 53.07
$53.07 is the total
