Answer:
Wednesday is 45 to 18.
Thursday is 55 to 22
Step-by-step explanation:
Wednesday: The original ratio was 5 to 2 And the info tells us that the new ratio is ? to 18. To find the first part we have to find how we got from 2 to 18. 2 * 9 = 18. So to find out the first part you do 5 * 9 = 45. We multiply 5 because Thats the original 1st part. We multiply 9 because that's how we got to 18 in the 2nd part. So the answer is 45 for Wednesday.
Thursday: The original ratio was 5 to 2 And the info tells us that the new ratio is 55 to ?. To find the first part we have to find how we got from 5 to 55. 5 * 11 = 55. So to find out the 2nd part you do 2 * 11 = 55. We multiply 2 because That's the original 2nd part. We multiply 11 because that's how we got to 55 in the 1st part. So the answer is 22 for Thursday.
The value of the expressions (2.5 × 10⁻³) and (7.1 × 10⁶) in scientific notation is 3.5211 × 10⁻¹⁰. Then the correct option is B.
<h3>What is division?</h3>
The division means the separation of something into different parts, sharing of something among different people, places, etc.
The expressions are 2.5 × 10⁻³ and 7.1 × 10⁶.
We have to divide 2.5 × 10⁻³ from 7.1 × 10⁶.
The value of the expressions (2.5 × 10⁻³) and (7.1 × 10⁶) in scientific notation is 3.5211 × 10⁻¹⁰. Then the correct option is B.

Answer:
No solution
Step-by-step explanation:
A = (b1 + b2)h/2
A = 35 cm²
h = 16 cm
b1 = 25 cm
b2 = ?
35 = (25 + b2)(16)/2
70 = (25 + b2)(16)
70 = 400 + 16b2
16b2 = 330
b2 = 330/16 = -20.625
The answer is a negative number. Since the base of a trapezium cannot have a negative length, there does not exist a trapezium with the given information.
