I believe the answer is (4.2)(10⁻⁵)
Answer:
$420
Step-by-step explanation:
Given that the students save$20 every week this can be written as;
1 week= $20 saved
For 21 weeks, you perform multiplication
1w=$20
21weeks=?------------perform cross multiplication
21*20=$420
Answer:
The dimensions are <u>15 x 6</u>
Step-by-step explanation:
Length (L) Width (W)
Perimeter = (W x 2) + (L x 2)
L = (W x 2) + 3
L x 2 = (W x 4) + 6
42 - 6 = 36
36 ÷ 6 = 6
6 x 2 + 3 = 15
<u>Perimeter = (6 x 2) + (15 x 2) = 42</u>
The probability of landing on the shaded region of the figure is 0.10
<h3>How to find the probability of landing on the shaded region?</h3>
The probability of landing on the shaded region can be calculated as follows;
area of the bigger circle = πr² = 3.14 × 25² = 1962.5 cm²
area of the smaller region = πr² = 3.14 × 8² = 200.96 cm²
Therefore,
the probability of landing on the shaded region of the figure = 200.96 / 1962.5
the probability of landing on the shaded region of the figure = 0.10
