Answer:
x=10/3 or x=3 1/3
(Same thing)
Step-by-step explanation:
First, we distribute the 3 to 2x and 5:
6x+15=19+16
6x=20
x=20/6
x=10/3
x=3 1/3
41) Circumference of a circle is 2*pi*radius, or pi*diameter.
Diameter given is 0.5cm, so circumference is 0.5pi, approximately 1.57cm.
It says scale is 1 cm to 2.5ft. Use dimensional analysis. You can multiply by 2.5ft / 1 cm because it equals 1, and multiplying by 1 doesn't change the value (just the units here).
1.57cm * 2.5ft
-------- = 3.925ft
1 cm
C) 4 feet
42) 6% of $900 is 0.06*$900, which is $54.
$900 is including tax, so subtract the tax ($54) to get the price before tax.
$900 - $54 = $846
A) $846
Answer: The required probability is 41%.
Step-by-step explanation:
Since we have given that
Probability that he will be hired in their first 6 month out of college = 59% = 0.59
So, we know that
total probability = 100% = 1
Probability that he will not get hired in the first 6 months out of college would be
Hence, the required probability is 41%.
Answer: the cost of one pair of shoes is $36.99
Step-by-step explanation:
Let d represent the cost of one pair of shoes.
While shopping for his triplet girls, he bought 10 pairs of socks for 2.50$ each and 3 pairs of shoes. The expression for the total cost of his purchase is
(2.5 × 10) + (3 × x)
= 25 + 3x
If he spent a total of $135.97, then the equation would be
25 + 3x = 135.97
3x = 135.97 - 25
3x = 110.97
x = 110.97/3
x = 36.99
