Answer:
She needs 32 quarters.
Step-by-step explanation:
d = dime q = quarters
d + q = 28 so d = 28-q
0.1d + 0.25q = 5.50
0.10 * (28-q) + 0.25q = 5.50
2.80 - 0.10q + 0.25q = 5.50
0.15q = 5.50 - 2.80
0.15q = 2.70
q = 2.70 / 0.15
q = 18 quarters (she has)
50-18= 32 quarters (she needs)

Calculate the simple interest on $600 left in account that pays 7% annual interest for 8 years.
Answer:
S = $336
Step-by-step explanation:
Given the following data;
Principal, P = $600
Rate, R = 7
Time, T = 8 years
To find the simple interest?
Mathematically, it is given by the formula;
Simple interest, S = (P*R*T)/100
Substituting into the equation, we have;
S = (600*7*8)/100
Simplifying the equation, we have;
S = 6*7*8
S = $336

MISSING PART OF QUESTION:
Consider the population of four juvenile condors. Their weights in pounds are : 5, 6, 10, 13
Answer:
The unique weights are 5, 6, 10 and 13
Step-by-step explanation:
Given
Weights: 5, 6, 10, 13 pounds
Required
Determine the unique weights of the juvenile
From the question, we understand that the weights of the juveniles could be any of 5 pounds, 6, 10 or 13 pounds
These values are the unique weights of the juveniles.
In other words, any value other than 5, 6, 10 or 13 can not be regarded as weights of the juveniles.
Hence, the unique weights are 5, 6, 10 and 13

if f(x) = a^x. and f(4) = 256 find f(5). assume a>0
Answer:
[tex]f(5)=1024[/tex]
Step-by-step explanation:
We have the function:
[tex]f(x)=a^x[/tex]
Where a>0.
We know that f(4)=256. Therefore:
[tex]\displaystyle f(4)=a^4=256[/tex]
So:
[tex]a^4=256[/tex]
Find the value of a. Take the fourth root of both sides:
[tex]a=\sqrt[4]{256}=4[/tex]
Therefore, our function is:
[tex]f(x)=4^x[/tex]
Hence:
[tex]f(5)=4^5=1024[/tex]

The probability that the photo also has a pet is 0.17
What is the probability?Probability refers to a possibility that deals with the occurrence of random events.
The probability of all the events occurring need to be 1.
We are given that recent survey has shown that 68% of professional photos are of humans, 39% are of pets, and 17% are of both humans and pets.
We need to find the probability that the photo also has a pet.
Therefore,
P(a pet) = 39% = 0.39
P(humans) = 68% = 0.68
P(both humans and pets) = 17% = 0.17
This gives;
P(the photo also has a pet) = 0.17
The probability that the photo also has a pet is 0.17

Write an equation in point-slope form and slope-intercept form for
each line.
the line passes through (4, 7), slope = 2
Answer: y=2x-1
Step-by-step explanation:
Equation of a line that passes through (a,b) and have slope m is given by :-
[tex](y-b)=m(x-a)[/tex] [point slope form]
Given, Point = (4,7) , m= 2
Equation in point slope form : [tex](y-7)=2(x-4)[/tex]
To write in slope intercept form (y=mx+c) , we need to simplify it
[tex]y-7= 2x-8\\\\\Rightarrow\ y-2x=-8+7\\\\\Rightarrow\ y-2x=-1\\\\\Rightarrow\ y=2x-1[/tex]
Hence, y=2x-1

Find the domain of the relation {(0, 0), (1, 1), (2, 0)). Then determine whether
the relation is a function.
Answer:
Domain: 0,1,2
The relation is a Function.
Step-by-step explanation:
hope this helps
A relation may or may not be a function.
The domain of the relation is: [0,2]The relation is a functionThe relation is given as:
[tex]\mathbf{(x,y) = \{(0,0),(1,1),(2,0)\}}[/tex]
List out the x-values
[tex]\mathbf{x = \{0,1,2\}}[/tex]
The above set means that the x-values starts from 0 and ends at 2.
Hence, the domain is: [0,2]
For a relation to be a function, all y-values of the relation must point to different x-values.
So, we can say that, the given relation is a function, because all y-values have unique x values

A dishonest shopkeeper has two false balances. One balance weighs 10% more while
buying the goods and other weighs 10% less while selling the goods. Find his gain
percent just by weighing,
Answer:
Shopkeepers gain just by weighing is 22.22%
Step-by-step explanation:
Explanation:
Assume that the shopkeeper bought x units of goods i.e. actual weight of goods.
As the balance used to buy goods weighs 10% more, he actually bought x×110100=1.1x weight units i.e. although the shopkeeper paid for x units, he actually bought 1.1x units by weight.
Now he has 1.1x units of goods, but for selling he uses another balance, which actually measures 10% less i.e. 1−0.10=0.9 units for each unit weight of goods sold.
So while selling 1.1x becomes 1.1x0.90=1.2222... units.
Hence, shopkeepers gain just by weighing is 22.22%
