For the following year we have the value is:
((100-15) / (100)) m
Rewriting we have:
((85) / (100)) m
0.85m

PLEASE HELP THIS IS A TIMED QUESTION ON A QUIZ!!!

pantera1 [17]

Answer:

a) 11, d) 25, e) 14, b) 25, c) 28, f) 33

Step-by-step explanation:

<h3>Given</h3>

ΔBDF, with H is the centroid of BDF, DF = 50, CF = 42, and BH = 22

HE , DE , CH, EF, HF, BE

<h3>Solution</h3>

As per definition of the centroid, the points C, E and G are midpoints of respective sides and the length of short and long distances from the centroid have ratio of 1/3 and 2/3 of median

a) HE = 1/2BH = 1/2(22) = 11
d) DE = 1/2DF = 1/2(50) = 25
e) CH = 1/3CF = 1/3(42) = 14
b) EF = DE = 25
c) HF = 2/3CF = 2/3(42) = 28
f) BE =BH + HE = 22 + 11 = 33

What is a rational number between 7.7 and 7.9

Luda [366]

Hey mate ,

here is your answer

**********************

The average between any two rational numbers is also rational.
(7.7 + 7.9)/2 = 7.8
7.8 is rational because it can be written as a fraction with integer numerator and denominator (39/5) and it is also a terminating decimal.

At the movie theatre, child admission is S5.20 and adult admission is $8.30. On Tuesday, 156 tickets were sold for a total sales

Annette [7]

Answer:

So, 89 Adult tickets were sold.

Step-by-step explanation:

So, we first name our variables, say, a for number of adult tickets, and c for child tickets.

Then we write our system of equations, first the total $ sale:

5.2c + 8.3a = 1087.10

Then we write the 2nd equation, the total number of tickets:

c + a = 156

Now, we can solve the system:

We do have different methods, let's to by subsitution.

make some change to the 2nd equation, to make c the subject: c = 156 - a

Now we plug that into the 1st equation:

5.2(156 - a) + 8.3a = 1087.10

811.2 - 5.2a + 8.3a = 1087.10

811.2 + 3.1a = 1087.10

3.1a = 275.9

a = 89
