Wilma has 28 coins, all nickels, and dimes worth $2.05. How many nickels does she have?
Answer:
15 nickels and 13 dimes
Step-by-step explanation:
5n + 10d = 205 cents
n + d = 28
n = 28-d
5(28-d) +10d = 205
140 -5d + 10d = 205
5d = 65
d = 13
n = 28-d = 28-13 = 15
5n = 5(15) = 75
10d = 10(13) = 130
75+130=205
Simplify the expression:
8 ( 5w + 7) + 9 (4w - 7)
Answer:
40
Step-by-step explanation:
Answer: 1.Remove any grouping symbol such as brackets and parentheses by multiplying factors.
2.Use the exponent rule to remove grouping if the terms are containing exponents.
3.Combine the like terms by addition or subtraction.
4. Combine the constants
Step-by-step explanation:
[tex]8(5w+7) + 9 ( 4w- 7)[/tex]
The first thing we do is distribute
[tex]8(5w+7)& 9(4w-7)[/tex]
We distribute what is outside the parenthesis to everything that is inside the parenthesis
so for 8(5w+7) we do [tex]8x5w = 40w[/tex] and [tex]8x7 = 56[/tex]
so for 9 So 9(4w−7) turns into 36w+63
so now we have 40w+56+36w+−63
now combine like terms
(40w+36w)+(56+−63)=?
Find the measure of angle b.
62°
65°
A) 45°
C) 54°
B) 59°
D) 53
Answer:
D) 53°
Step-by-step explanation:
I am assuming that you are talking about a triangle and those two numbers, 62 and 65 , are the degrees of the two angles.
The sum of the measures of the interior angles of a triangle is 180°.
62 + 65 + b = 180
180 - 127 = 53°

The equation x(x + 12) = 0 have 2 solutions.
What is an equation?Two algebraic expressions having same value and symbol '=' in between are called as an equation.
Given:
An equation,
x(x + 12) = 0
To find the solution:
x = 0 and x = -12.
Therefore, x = 0 and x = -12 are the solutions.

This question is incomplete, the complete question is;
A fair coin is tossed three times and the events AA, BB, and CC are defined as follows: A:{A:{ At least one head is observed }} B:{B:{ At least two heads are observed }} C:{C:{ The number of heads observed is odd }} Find the following probabilities by summing the probabilities of the appropriate sample points (note that 0 is an even number): a) P(B) =, b) P(A or B) =
Answer:
a) probability of B is 0.5
b) probability of (A or B) is 0.875
Step-by-step explanation:
Given the data in the question;
The coin is tossed 3 times.
so let S represent the sample space with the probabilities;
S = [ HHH, HHT, HTH, THH, HTT, THT, TTH, TTT ]
so n(S) = 8
now let A be the set where at least one head is observed;
A = [ HHH, HHT, HTH, THH, HTT, THT, TTH, ]
n( A) = 7
let B be the set where at least two head is observed;
B = [ HHH, HHT, HTH, THH, ]
n(B) = 4
let C be the set where number of heads are odd;
C = [ HHH, HTT, THT, TTH ]
n(C) = 4
so
a) P(B) = ?
probability of B will be;
P(B) = n(B) / n(S)
we substitute
P(B) = 4 / 8 = 0.5
Therefore, probability of B is 0.5
b) P(A or B) = ?
the favorable number of cases to event A∪B is
A∪B = [ HHH, HHT, HTH, THH, HTT, THT, TTH, ]∪[ HHH, HHT, HTH, THH, ]
A∪B = [ HHH, HHT, HTH, THH, HTT, THT, TTH, ]
n(A∪B) = 7
Now the probability of A or B will be
P( A∪B ) = n(A∪B) / n(S) = 7/8 = 0.875
Therefore, probability of (A or B) is 0.875
