The measure of ∠CBD is 23, because you can see that angle ABD and angle CBD are complementary angles equaling 90 degrees. And i believe AC is 8 just like BD
Given:
Cards labelled 1, 3, 5, 6, 8 and 9.
A card is drawn and not replaced. Then a second card is drawn at random.
To find:
The probability of drawing 2 even numbers.
Solution:
We have,
Even number cards = 6, 8
Odd numbers cards = 1, 3, 5, 9
Total cards = 1, 3, 5, 6, 8 and 9
Number of even cards = 2
Number of total cards = 6
So, the probability of getting an even card in first draw is:



Now,
Number of remaining even cards = 1
Number of remaining cards = 5
So, the probability of getting an even card in second draw is:


The probability of drawing 2 even numbers is:



Therefore, the probability of drawing 2 even numbers is
. Hence, the correct option is (b).

Answer:</h2>
To solve this system, we will use the graphing method.
Based on the graph shown below, we can conclude that this system has infinite solutions, because they are the same line.
Answer:
57.4g
Step-by-step explanation:
32.8g of sugar is needed to make 4 cakes. How much sugar is needed for 7 cakes?
From the above questions, we know that:
4 cakes = 32.8g
7 cakes = x g
Cross Multiply
4 × xg = 7 × 32.8g
x = 7 × 32.8g/4
x = 57.4 g
Therefore, 57.4g is needed for 7 cakes
