Some loose change (pennies, nickels, dimes, and quarters) found behind the couch. Brianna noticed more than half the coins were pennies. Geofrey noticed that there was at least one coin of each type. Michele noticed that you could not make change for the same amount using fewer coins. In the space below, write the total amount of change, in cents, that was found.
The total amount of change, in cents, that was found is determined as 96 cents.
Total amount of change
The total amount of change is calculated as follows;
let the total = T
there was at least one coin of each type
T = p + n + d + q
more than half of the coins were pennies
[tex]\frac{p+n + d + q }{2} \leq p[/tex]
Value of the coinspennies = $0.01nickels = $0.05dimes = $0.1quarters = $0.25more than half = pennies
next, we have; nickels + dimes + quarters
number of dimesy(dimes) = $0.25
y(0.1) = 0.25
y = 0.25/0.1
y = 2.5 ≅ 3
dimes = 3 coins
number of nickelssince dimes = 3 coins, number of nickels is now calculated as;
x(0.05) = 3(0.1)
x = (0.3)/(0.05)
x = 6 coins
nickels = 6 coins
Total coinsTotal coins = nickels + dimes + quarters + pennies
pennies must greater than 6 coins, since we can't have fewer coins.Total coins = nickels + dimes + quarters + pennies
let pennies = 7
Total coins = 6 + 3 + 1 + 7
Total coins = 17
half of 17 = 8.5
7 is less than half (8.5), number of pennies cannot be 7, since more than half of the coins are pennies.
let pennies = 11
Total coins = 6 + 3 + 1 + 11
Total coins = 21
half = 10.5
11 is more than half (10.5)more than half = number of pennies = 11
Total amount in cents11($0.01) + 6($0.05) + 3($0.1) + 1($0.25) = $0.96 = 96 cents

15. Suppose a kite is being flown with 135 meters of string. If the kite forms
a 47° angle with the level ground as shown in the diagram below, how
high is the kite to the nearest meter?
Answer:
99 m to nearest metre.
Step-by-step explanation:
Hypotenuse = 135, opposite side = ?
- so we need the sine function
sin 47 = x / 135 were x is the height of the kite.
x = 135 * sin 47
= 98.73 m

Find the slope of the graph of C
Step-by-step explanation:
the slope of a line or linear equation is always the factor of the driving variable.
usually in the form of
y = ax + b
x is the variable, and a the slope.
but in our case the variable is called "n".
it does not matter, the same principle applies.
the slope is the factor of n : 1050.
and as the slope is always the ratio y/x, we are looking for a fraction form, and that would be 1050/1.
so, the third answer is correct.
Maria started the year with $235 in the bank and is saving $15 a week. Sergio started with $685 and is spending $35 a week. When will they both have the same amount of money in the bank? Write an equation(s) to represent the situation and then solve. Be sure to define your variable(s) and clearly answer the question.
Answer:
9 weeks
Step-by-step explanation:
let the time when they will both have the same amount be x
since Maria is saving then her money is bound to increase
therefore amount she will have after x weeks=235+15x
Sergio is spending so his money is reducing
therefore amount he will have after x weeks=
685-35x
so
235+15x=685-35x
685-235=15x+35x
450=50x

Answer:
x = 104°
Step-by-step explanation:
The 142° and <DCE form a straight line, and a straight line measures 180°, do the two angles add up to it:
180° = 142° + m<DCE
m<DCE = 38°
The red symbol in <DCE and <CDE mean they are congruent, so m<CDE is the same as m<DCE, which is 38°.
The 142° angle is an exterior angle to triangle, DCE, an exterior angles are the sum of the remote interior angles, which are <CDE and <DEC. Therefore, we can write:
142° = m<CDE + m<DEC
And we can substitute the values we have:
142° = 38° + x
x = 104°

There are two numbers and one is 7 more than twice the other. the sum of the numbers is 43. What are the numbers
By solving a little system of equations we will see that the two numbers are 12 and 31.
How to find the numbers?
Let's define the two numbers as a and b.
We know that one of the numbers is 7 more than twice the other, so we have:
a = 2b + 7
We also know that the sum of the two numbers is 43, so we get:
a + b = 43
Replacing the first equation into the second one we get:
2b + 7 + b = 43
3b = 43 - 7 = 36
b = 36/3 = 12
Now that we know b, we can find a:
a = 2*12 + 7 = 31
So the numbers are 12 and 31.

Answer:
x = 20
y = √3 / 10
Step-by-step explanation:
The cosine ratio gives the ratio between the adjacent side and the hypotenuse.
The sine ratio gives the ratio between the opposite side and the hypotenuse.
Taking cosine ratio to find x :
cos 60° = 10/x
1/2 = 10/x
x = 20
Taking sine ratio to find y :
sin 60° = y/x
√3 / 2 = y/20
y = √3 / 10
Answer:
x= 20 , y= 10√3
Step-by-step explanation:
This question is clearly a trigonometry question
Please bare in mind :
Cos 60 = 1/2
Sin 60 = √3/2
Tan 60 = √3
Side x is the hypotenuse (h)
Side y is the Opposite (o)
And side with length of 10 is adjacent (a)
To find x, we have a, and we need h
So we use C = a/h
Cos 60 = 10/h
h = 10/Cos 60
h = 10/0.5
h = 20 , x=20
To find y, we can use pythagaros as we found the value of x :
10² + y² = x²
10² + y² = 20²
y² = 20²-10²
y² = 300
y = √300
y= √100×3 y=√100 × √3
y = 10√3
This is our y value
Another way to find y is trigonometry :
We have a and we need o so we use :
T = o/a
Tan 60 = o/10
o = 10×tan 60
o = 10×√3
o = 10√3 , y=10√3

The measure of an angle is 5°. What is the measure of its supplementary angle?
Answer:
175 degrees.
Step-by-step explanation:
Supplementary angles add up to 180 degrees
Therefore the answer is:
180 - 5
= 175 degrees.
Hi Student!
The first step to almost any problem is that we must concentrate the important information that is given to us in the problem. This problem gives us information including that the measure of an angle is 5 degrees and that this angle is part of a supplementary pair. Let's define what a supplementary pair or angles are.
Supplementary Angles: These are two angles that are right next to each other on a straight line. These angles combine to a total of 180 degrees.Complementary Angles: These are two angles that are right next to each other but this time they are on a right angle. These angles combine to a total of 90 degrees.Now that we have our definitions and important information, we can move onto the next part which is actually finding the other angle. This step is simple now that we know that supplementary angles add up to 180. We can just create an equation that will help us determine our solution.
[tex]angle_1\ +\ angle_2 = 180\ degrees[/tex]
[tex]5\ degrees\ +\ angle_2 = 180\ degrees[/tex]
[tex]5\ degrees-5\ degrees\ +\ angle_2 = 180\ degrees-5\ degrees[/tex]
[tex]angle_2 = 175\ degrees[/tex]
Therefore, our final solution to the supplementary angle of 5 degrees is 175 degrees which can be found by subtracting the given angle from 180.

Angles ABC and EDC are clearly congruent, since they are both right angles.
The legs AB and ED are parallel, so angles BAC and DEC are congruent alternating interior angles.
Then ∆ABC is similar to ∆CDE by the angle-angle-angle postulate.
b) Because they're similar, corresponding sides occur in a fixed ratio, which tells us that
