Mathematics
1 answer:
posledela3 years ago
7 0

Answer:

40

Step-by-step explanation:

given the fact that mary made 85% of her free throws attempts,

thus she missed the rest 100 minus 85= 15% of the attempts. let the total number of attempts be x. thus:

15% of x=6

15/100 x=6

solve by cross multiplying

x=6  100/15

x=40

hope this helps

Angelo earns $2,080 each month. His total deductions are 30% of his pay. How much is deducted from his pay each month? 
Fofino [41]
C. $693.33. Just round. It helps. Round 2,080 to 2,100. Then whats 30% of 2,100? It's easy just think of 21 divided by 3, which equals 7. So, 700 and the closest answers to that is $693.33. That's just the easy way instead of doing the math out. And it is also common sense that B or D wouldn't be it. So your left with C or A. :)

Maddie biked 8 3/4 miles today, and Chase bikes 3 1/2 miles. How many times the length of Chase’s bike ride was Maddie’s bike ri
borishaifa [10]

Answer: 2.5 times

Step-by-step explanation:

Given : The length of Chase’s bike ride= 8\dfrac{3}{4}\ miles

The length of Maddie’s bike ride=3\dfrac{1}{2}\ miles

In improper fraction : Length of Chase’s bike ride=\dfrac{4(8)+3}{4}\ miles

=\dfrac{35}{4}\ miles

Similarly , Length of Maddie’s bike ride= \dfrac{7}{2}\ miles

The number of times the length of Chase’s bike ride was Maddie’s bike ride= \dfrac{\text{ Length of Chase’s bike ride}}{\text{ Length of Maddie’s bike ride}}

=\dfrac{\dfrac{35}{4}}{\dfrac{7}{2}}\\\\=\dfrac{5}{2}=2.5

Hence, the length of Chase’s bike ride was 2.5 times Maddie’s bike ride.

Please help and show all work so I can fully understand it, thanks.
seraphim [82]

Answer:

\frac{1}{m-4}

Step-by-step explanation:

\frac{\frac{4m-5}{m^4 -7m^3 +12m^2}}{\frac{4m-5}{m^3 -3m^2}}

Factor the equation:

\frac{\frac{4m-5}{m^2(m^2 -7m+12)}}{\frac{4m-5}{m^2(m-3)}}

\frac{\frac{4m-5}{m^2(m-3)(m-4)}}{\frac{4m-5}{m^2(m-3)}}

Rewrite to suit the format of multiplying two fractions. Remember, dividing two fractions is the same as multiplying the first fraction by the reciprocal of the second. A reciprocal of a fraction is when one switches the place of the numerator and the denominator, that is, the value on top (numerator), and the value on the bottom (denominator).

\frac{4m-5}{m^2(m-3)(m-4)}*\frac{m^2(m-3)}{4m-5}

Simplify, take out common terms that are found on both the numerator and denominator

\frac{4m-5}{m^2(m-3)(m-4)}*\frac{m^2(m-3)}{4m-5}

\frac{1}{m-4}

A treasure map says that a treasure is buried so that it partitions the distance between a rock and a tree in a 5:9 ratio. Marin
Tanya [424]
Let the coordinates of the treasure be (x,y).
Let d_{1} =  distance from the rock to the treasure.
Let d_{2} =  distance from the tree to the treasure.
 d_{1} = \sqrt{(x\2 + (y-2)^2}
d_{2} = \sqrt{(16-x)^2 + (21-y)^2}
We want \frac{ d_{1} }{ d_{2} } = 5/9 in order to locate the treasure. 

Note that 5/9 = 0.556 (approx)
Test (11.4, 14.2)
d1 = 14.8, d2 = 8.2, d1/d2 = 1.8           Incorrect
Test (7.6, 8.8)
d1 = 8.2,  d2 = 14.8,  d1/d2 = 0.554    Correct
Test (5.7, 7.5)
d1 = 6.13,  d2 = 16.98,  d1/d2 = 0.36   Incorrect
Test (10.2, 12.6)
d1 = 12.8,  d2 = 10.2,  d1/d2 = 1.255   Incorrect

Answer: The correct answer is (7.6, 8.8)
