Answer:
20 cm
Step-by-step explanation:
5n × 3n = 2×120
15n²=240
n²=240/15 =16
n=√16 = 4
base = 5× 4 = 20
Step-by-step explanation:
A. Base = <em><u>(-3)</u></em>
B. Exponent = <em><u>5</u></em>
C. (-3)^5
= <em><u>(-3) × (-3) × (-3) × (-3) × (-3) (In expanded notation form)</u></em>
D. Evaluation of equation will be = <em><u>-243</u></em>
GIVEN:
Cost of a taco and a cup of tea = $2.10
Cost of 2 tacos and 3 cup of tea = $5.15
ANSWER:
On solving eq(1), we get
Substitute the value of x in eq(2), we get
- 2(2.10 – y) + 3y = 5.15
- 4.20 – 2y + 3y = 5.15
- y = 5.15 – 4.20
- y = 0.95
So, x = 2.10 – 0.95
Hence, Cost of a taco is $1.15
So, <u>Correct choice</u> - [E] $1.15
If two lines intersect, then there are two possibilities
A) The lines intersect at exactly one point. This happens if the slopes of the two lines are different (the y intercepts may or may not be the same).
B) The lines intersect at infinitely many points. This happens when both slopes are the same and when both y intercepts are the same. In short, the two equations are identical. Often they may be written in different forms. For example, the equation y = 2x+1 and 2y = 4x+2 are the same equation. Divide everything in equation (2) by 2 and you'll get equation (1).
Answer:
I believe 25%
Step-by-step explanation:
There are four equally likely outcomes: HH, HT, TH and TT. Of these, one of these match the criterion given ("the first will come up heads and the second tails”). So the probability is 1/4= 25%.
