Answer:
1 3/4 = 7/4 = 1.75
Step-by-step explanation:
The process to arrive to the solution is explained in the pictures below.
Tyler needed to convert the mixed fraction
2 1/2 = (4+1)/2 = 5/2
If we multiply by 2 numerator and denominator
5*2/2*2 = 10/4
We substract
10/4 - 3/4 = 7/4 = 1.75
Answer:
$4
Step-by-step explanation:
Trey sold his $80 hockey stick for 25% less. This means that he received 75% of the $80. Convert the percentage to a decimal, so it will be .75. Multiple .75 by $80 and you will get the final answer which is $60.
Brandon sold his $80 hockey stick for 30% less. This means that he received 70% of the $80. Convert the percentage to a decimal, so it will be .70. Multiple .70 by $80 and you will get the final answer which is $56.
Trey received $4 more for his hockey stick.
Answer:
y - 12 = 9(x - 4)
Step-by-step explanation:
The vertex (h, k) is (4, 12) and the point (5, 21) is on the graph. Assuming that this is a vertical parabola, opening up (because the coordinate 21 is greater than the coordinate 12), we insert the knowns into y - k = a(x - h)^2, obtaining
21 - 12 = a(5 - 4), or 9 = a. With a known, we can write the desired equation:
y - 12 = 9(x - 4)
The answer is 110.
The 55 degree angle is related to arc B. The measure of arc B is double the measure of the angle. So, arc B covers 55*2=110 degrees.
