Suppose you have budgeted for 3 expenditures, $100, $150 and $50. However the amount that you have spent is $95, $175 and $20. Did you spend more or less than what was budgeted? By how much? (Show Your Work)
Answer:
Spent less than budget by $10
Step-by-step explanation:
→ Work out total budget
100 + 150 + 50 = 300
→ Work out total expenditure
95 + 175 + 20 = 290

in a bag of keys there are 15 silver keys six black keys 11 copper keys and two painted keys of various colors. one key is drawn what is the probability that the key is silver or copper
Answer:
The best thing to do here is to put each of these into fractions, with the total (31) as the denominator.
14/31= silver
6/31= black
8/31= copper
3/31= various colours.
As you're looking for the keys that are silver or copper, you've got to add the two denominators together, which gives you 14+8= 22.
This cannot be simplified further, therefore, the probability of choosing either a silver or copper key is 22/31.
Hope this answer helps you :)

Answer:
Step-by-step explanation:
y= mx+ b helps you find the equations of the lines
y= x+2 is the line with slope m=1, and y-intercept b=2
y= -4x-3 is the line with slope m=-4, and y-intercept b=-3
y > x+2 because is a dotted line
y ≤ -4x-3 because is a solid line

Triangle JKL has the coordinates listed: J (5, -8), K (10, -8), L (7, -4) Where is J’ after a reflection over the y-axis?
The Rule for reflection over the y-axis is given by (x,y) to (-x,y).
so, J' (-10,-8)
✐----------------------
hope it helps...
have a great day!
Answer:
J' Coordinates = (-5, -8)
Step-by-step explanation:
We know that in the coordinate point J (5, -8);
x-value = 5
y-value = -8
In order to reflect J over the y-axis, we will keep the y-value of the coordinate same and then reverse the x-value to it's opposite, Therefore the J' coordinates would be;
x-value = -5
y-value = -8
J' Coordinates = (-5, -8)

Find the area of a circle with the radius of 73 feet
Answer:
Step-by-step explanation:
area of a circle=πr^2
=3.14*(73)^2
=3.14*5329
=16733.06 ft^2
Answer:
A = 5329 pi ft^2
If we approximate pi with 3.14
A = 3.14*5329=16733.06 ft^2
If we use the pi button
A =16741.54725 ft^2
Step-by-step explanation:
The area of a circle is given by
A = pi r^2
The radius is 73
A = pi ( 73) ^2
A = 5329 pi ft^2
If we approximate pi with 3.14
A = 3.14*5329=16733.06 ft^2
If we use the pi button
A =16741.54725 ft^2

Jimmy and Jennifer are selling pies for a school fundraiser. Customers can buy apple pies and blackberry pies. Jimmy sold 10
apple pies and 2 blackberry pies for a total of $80. Jennifer sold 10 apple pies and 3 blackberry pies for a total of $100. Find the
cost each of one apple pie and one blackberry pie.
Answer:
One apple pie is $4 and one blackberry pie is $20
Step-by-step explanation:
Create a system of equations where a is the cost of one apple pie and b is the cost of one blackberry pie:
10a + 2b = 80
10a + 3b = 100
Solve by elimination by multiplying the top equation by -1, then adding the equations together:
-10a - 2b = -80
10a + 3b = 100
Add these together:
b = 20
So, one blackberry pie is $20. Plug in 20 as b into one of the equations, and solve for a:
10a + 2b = 80
10a + 2(20) = 80
10a + 40 = 80
10a = 40
a = 4
So, one apple pie is $4.
One apple pie is $4 and one blackberry pie is $20

Answer:
●{22,28,35} ○{5,12,13}○{25,70,74} ○{48,56,73}Which expression is equivalent to (3x + 4)(2x - 3)?
Answer:
Step-by-step explanation:
If there are choices, you should list them. It's a guess about which is correct. I'll list 2 of them.
(3x + 4)(2x - 3) can be
(2x - 3)(3x + 4) or
F: 3x*2x = 6x^2
O:3x * -3 = - 9x
I : 4 * 2x = 8x
L: 4 * - 3 = - 12
When added, you get
6x^2 -9x + 8x - 12
6x^2 - x - 12

Factorize x^2 -9
Answer:
(x + 3) (x - 3)
Step-by-step explanation:
We know that;
a = 1
b = 0
c = -9
We also know that;
p*q = -9
p + q = 0
In this case, it would make the p value 3, and q value -3
The factorized form would be;
(x + p) (x + q)
=> (x + (3)) (x + (-3))
=> (x + 3) (x - 3)
So therefore, the factorized form;
(x + 3) (x - 3)
Hope this helps!
Answer:
the answer is (x + 3)(x - 3)

Assume the selling price of your house calculate the
commission amount of your house if the commission rate
is 5•/•
Answer:
$14000
Step-by-step explanation:
Given that :
Commission 5% of sale price
Sale price of house = $280,000
Commission = 5% of $280,000
Hence,
Commission = 0.05 * $280,000
Commission = $14,000

Use the given area A of the rectangle to find the value of x . A rectangle with its length labeled left-parenthesis 4 x plus 3 right-parenthesis feet and width labeled left-parenthesis 4 x minus 5 right-parenthesis feet. The area of the rectangle is 209 square feet.
Answer:
x = 4
Step-by-step explanation:
Length = (4x + 3) feet
Width = (4x - 5 )feet
Area = Length x Breadth
209 = (4x + 3)(4x - 5)
209 = 4x( 4x -5) + 3 (4x -5)
[tex]209 = 16x^2 -20x +12x -15\\\\0 = 16x^2 -8x -15 -209\\\\16x^2 -8x -224 = 0[/tex]
[tex]Quadratic \ Equation \ with a = 16, b = -8, c = -224 \\\\x = \frac{-b \pm \sqrt{b^2 -4ac}}{2a}\\\\Substitute \ a, b, c \ in \ the \ equation.\\\\x = \frac{-b + \sqrt{b^2 -4ac}}{2a}, x =\frac{-b \ - \sqrt{b^2 -4ac}}{2a}\\\\x = \frac{8+ \sqrt{64 +14336}}{32}, x = \frac{8- \sqrt{64 +14336}}{32}\\\\x = \frac{8+ \sqrt{14400}}{32}, x = \frac{8-\sqrt{14400}}{32}\\\\x = \frac{8+120 }{32}, x= \frac{8-120}{32}\\\\x = \frac{128}{32} , x = \frac{-112}{32}\\\\x = 4 , x = \frac{-7}{2}[/tex]
Since measure of length or width cannot be negative, we take x = 4
