We base ourselves in the one piece of crucial evidence: She has 2 quarters.
-from the rest of the problem, we know that she has 2 more NICKEL'S than QUARTERS, 

(2 Quarters + 2 = 4 nickels)

she has 3 fewer nickels than dimes, 

DIME - 3 = Nickels

D - 3 = 4

D = 7

7 dimes
(70 cents)

4 nickels
(20 cents)

2 quarters
(25 cents)

115 cents
or $1.15

Pedro bought 8 tickets to a basketball game.he paid a total of $208.write an equation to determine whether each ticket cost $26
Mariana [72]
Pedro bought 8 tickets so
Number of tickets = 8, total cost = 208
Soo the equation is going to be:

8x = 208

Divide both sides by 8

8x/8=208/8

x = 26

Cost of each ticket was $26

a psychologist contends that the number of facts of a certain type that are remembered after t hours is given by the following f
laiz [17]

Answer:

At t=1, Rate of Change=-36.86

At t=10 hours, Rate of Change =-0.0088

Step-by-step explanation:

The function which describes the number of facts of a certain type which are remembered after t hours is given as:

f(t)=\frac{85t}{99t-85}

To determine the Rate of Change at the given time, we first look for the derivative of f(t).

Applying quotient rule:

f^{'}(t)=\frac{-7225}{{\left( 85 - 99\,t\right) }^{2}}

At t=1

f^{'}(1)=\frac{-7225}{(85-99)^{2}}

=-36.86

At t=10 hours

f^{'}(10)=\frac{-7225}{(85-99(10))^{2}}

=-0.0088

The length of the line segment joining the midpoints of sides AB and BC of the parallelogram ABCD is 10. Find the length of diag
solniwko [45]

Answer:

The length of the diagonal AC=20 cm.

Step-by-step explanation:

From ΔOBP and ΔABC, we have

\frac{OB}{AB}=\frac{BP}{BC}( O and P are mid points)

∠B=∠B(Common)

Therefore, by SAS rule,

ΔOBP is similar toΔABC

Thus, \frac{OB}{AB}=\frac{OB}{2OB}=\frac{1}{2}

⇒\frac{OP}{AC}=\frac{1}{2}

⇒AC=2{\times}OP

⇒AC=2{\times}10

⇒AC=20 cm

Thus, the length of the diagonal AC=20 cm.
