3Directions: Use the information in the charts to answer the questions. Type of Fruit Cost Estimated Cost apple $1.75/pound 8.75 orange $2.35/pound 9.40 banana $1.50/pound 4.50 Annie bought 5 pounds of apples, 4 pounds of oranges, and three pounds of bananas. a. Round the prices to the nearest whole dollar to estimate how much money she spent. b. How much money did Annie actually spend? Write a numerical expression to represent the amount of money that Annie spent. Was your estimation an overestimation or underestimation? Why do you think that might be?
Estimates are used to make prediction about an actual value
Annie estimated spending $52Annie actually spent $48.25Your estimation is an overestimationThe chart is given as:
Fruit Cost Estimated
Apple $1.75/pound 8.75
Orange $2.35/pound 9.40
Banana $1.50/pound 4.50
The number of pounds of each fruit Annie bought are:
[tex]Apples= 5[/tex]
[tex]Orange = 4[/tex]
[tex]Banana = 3[/tex]
(a) The estimated amount
To do this, we make use of the estimated column.
So, we have:
[tex]Estimated = \sum Cost \times Pounds[/tex]
[tex]Estimated =1.75*5+8.75*4+1.50*3[/tex]
Approximate the prices
[tex]Estimated =2*5+9*4+2*3[/tex]
[tex]Estimated =52[/tex]
Hence, Annie estimated spending $52
(b) The actual amount spent
To do this, we make use of the cost column.
So, we have:
[tex]Actual = \sum Cost \times Pounds[/tex]
[tex]Actual =1.75*5+8.75*4+1.50*3[/tex]
[tex]Actual =48.25[/tex]
Hence, Annie actually spent $48.25
(c) The decision
By comparison, the estimated spending is greater than the actual amount spent.
Hence, your estimation is an overestimation

Hector took out a small loan of $900 for 18 months. The simple interest rate on the loan was 10.5%. How much will he pay in interest on the loan?
Answer:
The answer would be $1.89 in interest.
Step-by-step explanation:
First, change 10.5% into a decimal. To do this, you divide 10.5÷100. This equals 0.105
next, you multiply 0.105 with 12 (12 months in a year)
This equals 1.26
But, Hector still has 6 months left he has to pay for.
So, one way you can do this is divide 1.26 by 2, which equals 0.63.
THEN, you add 0.63 with 1.26, giving you the answer, 1.89
So, the answer for this equation would be 1.89.

Answer:
61 Nickels and 39 Dimes
Step-by-step explanation:
you have $3 and 5 cents in nickels and 3$ and 90 cents in Dimes
it all equals 100 coins all together
The number of dimes is 39 dimes
The number of nickels 61 nickels
What is an Equation?
Equations are mathematical statements with two algebraic expressions flanking the equals (=) sign on either side.
It demonstrates the equality of the relationship between the expressions printed on the left and right sides.
Coefficients, variables, operators, constants, terms, expressions, and the equal to sign are some of the components of an equation. The "=" sign and terms on both sides must always be present when writing an equation.
Given data ,
Let the number of dimes be = x
Let the number of nickels be = y
So , total number of coins = 100
x + y = 100 be equation (1)
And , the total amount = $ 6.95
The cost of one dime = $ 0.10
The cost of one nickel = $ 0.05
So , total cost = 0.10x + 0.05y = 6.95 be equation (2)
Now , on simplifying equation (1) and equation (2) , we get
x + y = 100
10x + 5y = 695 be equation (3)
Divide equation (3) by 5 , we get
2x + y = 139 be equation (4)
Now , Subtracting equation (1) from equation (4) , we get
x = 39
Therefore , the number of dimes is 39 dimes
Substituting the value of x in equation (1) , we get
x + y = 100
y + 39 = 100
Subtract 39 on both sides of the equation , we get
y = 61
Therefore , the number of nickels is 61 nickels
Hence ,
The number of dimes is 39 dimes
The number of nickels 61 nickels

when,

b = -1
c = -4
= [- |a + b| / 2 ]- c

= [ - | 15/8 - 1 | / 2 ] + 4
= [ - | (15-8)/8 | / 2 ] + 4

= { -7/(8 x 2) ] + 4
= -7/16 + 4

Give an equation for the result of shifting the graph of up by 4 units, and left by 2 units.
An equation is written as two expressions connected by the equal sign
Enter an equation for the shifted graph:
We define transformations as operators that act on functions by modifying them in some given way. One type of transformation is a translation, which will move the whole graph of the function in some give direction.
For a general function f(x), we will find that the equation for the result of shifting the graph up by 4 units and left by 2 units is:
g(x) = f(x + 2) + 4
----------------------------------
Let's see how to solve this.
We need to start by defining the two most common translations (also known as shifts).
Horizontal translation:
For a given function f(x), an horizontal translation of N units is written as:
g(x) = f(x + N)
where if N is positive, the translation is to the left.
If N is negative, the translation is to the right.
Vertical translation:
For a given function f(x), a vertical translation of N units is written as:
g(x) = f(x) + N
Where if N is positive, the translation is upwards.
If N is negative, the translation is downwards.
Here for an unknown function f(x), we want to write the equation that gives a shift up of 4 units and left by 2 units.
The shift up of 4 units is written as:
g(x) = f(x) + 4
The shift of 2 units to the left is written as:
g(x) = f(x + 2)
These two together give:
g(x) = f(x + 2) + 4.
This is the equation we wanted to get.
