Answer:
Step-by-step explanation:10
Answer:
B
Step-by-step explanation:
Sin 64=23/a. Let use trig identities to find other points
First, since sin and cos like are complementary angles we can use this formula
sin 64=23/a
So cos 26=sin 64 so B is a answer
The answer is $45
Let's make the system of equations.
x - the cost of the car
y - the amount Matthew has
<span>Matthew currently has enough money to buy 45 toy cars:
y =45x
</span><span>If the cost of each car was 10 cents less, Matthew could buy 5 more cars:
y = (x - 10)*(45 + 5)
45x = (x - 0.10) * 50
45x = 50x - 5
5 = 50x - 45x
5 = 5x
x = 5 / 5
x = 1
y = 45x = 45 * 1 = $45</span>
