Answer:
my dude that likes crazy hard I feel bad for u cuz I've been trying to figure it out and still can't seem to get it and I even asked 3 adults and they couldn't help me either
Tax
$350x0.07
=$24.50
(0.07 is the 7% tax in decimal form)
Total cost
$350+$24.50
=$374.50
OR
$350x107%
=$374.50
1.07 is the table cost (100%) plus the sales tax (7%)
The table costs $374.50 with tax.
All of these questions will be exponents and variables.
The answer is b. The paired chromosomes overlap of dna
You have two 30-60-90 triangles, ADC and BDC.
The ratio of the lengths of the sides of a 30-60-90 triangle is
short leg : long leg : hypotenuse
1 : sqrt(3) : 2
Using triangle ADC, we can find length AC.
Using triangle BDC, we can find length BC.
Then AB = AC - BC
First, we find length AC.
Look at triangle ACD.
DC is the short leg opposite the 30-deg angle.
DC = 10sqrt(3)
AC = sqrt(3) * 10sqrt(3) = 3 * 10 = 30
Now, we find length BC.
Look at triangle BCD.
For triangle BCD, the long leg is DC and the short leg is BC.
BC = 10sqrt(3)/sqrt(3) = 10
AB = AC - BC = 30 - 10 = 20
