380/20 = 19
The car can go 19 miles on 1 gallon of gas.
75 * 19 = 1,425
You can drive 1,425 miles on 75 gallons.
Answer:
Yes
Step-by-step explanation:
You can get there a couple of ways. One makes use of the secant rules that tell you ...
PQ × PR = PS × PT
Substituting for PR and PT, you have ...
PQ × (PQ + QR) = PS × (PS + ST)
PQ² + PQ×QR = PS² + PS×ST
Substituting PQ for PS everywhere, we have ...
PQ² + PQ×QR = PQ² + PQ×ST
Dividing by PQ gives ...
PQ + QR = PQ + ST
and subtracting PQ leads us to the conclusion ...
QR = ST
_____
Another way to look at it is to draw the chord QS. Then ΔQPS is an isosceles triangle, and the perpendicular bisector of QS bisects ∠P and also goes through the circle center. Then the figure is symmetrical about that diameter secant, making QR ≅ ST.
The answer is the 3rd question
Option E
The numerator of fraction is 21
<h3><u>Solution:</u></h3>
is to be written as improper fraction in lowest terms
To find: numerator of fraction
An improper fraction is a fraction in which the numerator (top number) is greater than or equal to the denominator (bottom number).
<em><u>To convert a mixed fraction to an improper fraction, follow these steps:</u></em>
- Multiply the whole number part by the fraction's denominator.
- Add that to the numerator.
- Then write the result on top of the denominator.
Thus the numerator of fraction is 21. Option E is correct
