Step-by-step explanation:
.................b = 37.8
Answer:
To pay attention.
Step-by-step explanation:
Answer:
25/208 or 12.2%
Step-by-step explanation:
P(heart) = 13/52 = 1/4
P(red) = 26/52 = 1/2
because we are not replacing the first card drawn, the deck has 51 cards remaining
P(heart, red) = 1/4 × 25/52
= 25/208 or 12.2%
Answer:
17
Step-by-step explanation:
5-4b ; b=-3
- substitute b= -3 into the expression
5-4×(-3)
- multiply the numbers
(-4×(-3)=+12) 5+12
- add the numbers
(5+12=17)
SOLUTION: 17
The sum of the three angles of a triangle is always 180 degrees. If the triangle is right, which means one of the angles measures 90 degrees, the other two angles should add up to 90 degrees. With this condition and the given above, x + 15 + 2x = 90. Solving for x in the equation gives x = 25. Substituting x to the given expression for the acute angles gives the measurements of 40 and 50 degrees. Thus, the smallest angle of the triangle is <em>40 degrees</em>.
