Ng Order of Operations George has $15. He would like to know if he has enough money to see a movie ($9.00) and buy a pretzel ($2.65), a drink ($1.35), and two veggie cups ($1.74 each). George incorrectly used this numerical expression to decide if he had enough money. 15 - 9 + 2.65 + 1.35 + 2(1.74) Use the order of operations to simplify this expression.
Answer:
No, George does not have enough money to buy everything.
The correct expression is:
15 - 9 - 2.65 - 1.35 - 2(1.74)
Step-by-step explanation:
Given that:
Money present with George initially = $15
Money required to see the movie = $9
Money required to buy a pretzel = $2.65
Money required to buy a drink = $1.35
Money required to buy 2 veggie cups = $2(1.74)
To find:
Whether there is enough money with George to complete all the tasks.
Solution:
First of all, let us calculate all the money required and then we can subtract all the money from the initial amount to find whether there is enough money present with George.
If the result is in positive, there is enough money with George.
Total money required for all the activities = $9 + $2.65 + $1.35 + $2(1.74) = $16.48
Expression = $15 - $16.48 = -$1.48
The result is negative, therefore there is not enough money.
The correct expression is:
15 - 9 - 2.65 - 1.35 - 2(1.74)

Is this a square root graph?
Is this graph a reflection of its parent graph?
this graph shifted _
The equation to this graph would transform the parent function f(x) to _
Answer:
Thus, [tex]y=-\sqrt{x+3}[/tex] represents the transformed graph on the attached figure, which is a translated square root graph i.e. vertically reflected across the y-axis and also horizontally translated or shifted 3 units to the left.
Step-by-step explanation:
Consider the function
y = f(x)
The rule of horizontal translation
y = f(x-h)
When 'h' is positive, the function is shifted to the right.
When 'h' is negative, the function is shifted to the left.
The rule of implying vertical reflection across the x-axis
y = -f(x)
Applying the rule:
We know that the square root function is
[tex]y=\sqrt{x}[/tex]
We know that if the graph would be reflected across the x-axis, then
[tex]y=-\sqrt{x}[/tex]
We know that is horizontally translated or shifted 3 units to the left, it implies +
3 inside the radical implies. Then the transformed function becomes .
Please check the attached diagram. From the diagram,
The blue graph shows the parent function [tex]y=\sqrt{x}[/tex].The red graph shows the transformed function i.e. vertically reflected across the y-axis and also horizontally translated or shifted 3 units to the left.Thus, [tex]y=-\sqrt{x+3}[/tex] represents the transformed graph on the attached figure, which is a translated square root graph i.e. vertically reflected across the y-axis and also horizontally translated or shifted 3 units to the left.

Mark takes out a $238,000 mortgage for 30 years. Instead of paying his monthly payment of $1,220.09, he decided to pay $1,420.09. This leads to Mark paying off the entire mortgage in 22 years and 5 months. Mark calculates the percent of the total loan he pays back in interest with and without the extra payments. What is the difference between Mark's calculated percentages?
Answer:
24.04%
Step-by-step explanation:
Given that:
Mortgage = $238,000
Number of years = 30
Monthly payment without extra payment= $1220.09
Monthly payment with extra payment = $1420.09
Total amount paid :
Number of months * monthly payment
12 months = 1year
30 years = (30 * 12) = 360 months (without extra payment)
22 years 5 months = (22 * 12) + 5 = 269 months (with extra payment)
Amount paid without extra payment :
$1220.09 * 360 = $439232.4
Percentage of total loan paid as interest :
((439232.4 - 238000) / 238000) * 100%
= 0.8455142 = 84.55%
Amount paid with extra payment :
$1420.09 * 269 = 382004.21
Percentage of total loan paid as interest :
((382004.21 - 238000) / 238000) * 100%
= 0.6050597 = 60.51%
Difference between percentages:
84.55% - 60.51% = 24.04%
The radio station in North Pole, AK plays Christmas songs all day and night from Thanksgiving through Christmas. They play 12 per hour for 15 hours a day, and 8 songs per hour for the rest of the day. They like to have a mix of traditional and modern songs with a relationship of 9 traditional songs to every 5 modern songs. How many traditional songs and how many modern songs will they play in one day?
Answer:
Traditional = 162
Modern = 90
Step-by-step explanation:
Given that:
12 songs per hour for 15 hours
8 songs per hour for the rest of the day ; (24 - 15) = 9 hours ;
That is ; 8 songs per hour for 9 hours
Total number of songs played per day :
(12 * 15) + (8 * 9) = 252 songs
If songs are mixed using the ratio 9:5 (traditional : modern)
Traditional songs :
(9 * 252) / (9 + 5) = 162
Modern songs :
(5 * 252) / (9 + 5) = 90

Question 2 options:
A)
$10,240
B)
$11,874
C)
$5,892
D)
$9,399
Answer:
$10,240
Step-by-step explanation:
y = 20,000 (.80)^t
y = 20,000 (0.80)^3
0.8^3 = 0.512
0.512 x 20,000 = 10240
Your answer would be A. $10,240.

Tom and Jason both collect marbles Tom has collected 510 marbles and Jason has collected 842 marbles. How many marbles do they on together..?Estimate the total number of marbles nearest to hundred
Answer:
They had 1,352 marbles all together, rounded to the nearest hundred, 1,400.
Step-by-step explanation:
All we have to do is add the number of marbles they collected.
510 + 842 = 1,352
1,352 rounded to the nearest hundred is 1,400.

It's telling you to increase the side lengths by a factor of 3y
4x(3y) + 4x(3y) = 3y * 3y
12xy + 12xy = 9y^2
Perimeter = 24xy + 9y^2

A speed limit is 35 mph. A car is travelling 10 mph over the speed limit. I’d that a sum of 0
Answer:
The car is going 45 mph
Step-by-step explanation:
Since the speed limit is 35 mph and the car is 10 mph over the speed, we can add them to find out how fast the car is going. We can solve 35+10 which will give us 45. So it is not a sum of 0 but instead a sum of 45.
(hope this helped)
Answer:
35+10 =45
Step-by-step explanation:
add 10 to 35 then divide by 2
A spherical balloon is inflated with gas at a rate of 500 cubic centimeters per minute. (a) How fast is the radius of the balloon changing at the instant the radius is 40 centimeters
Answer:
[tex]\mathbf{ \dfrac{dr}{dt} = 0.03730 \ cm/min}[/tex]
Step-by-step explanation:
The rate of the inflation of the balloon with time can be denoted as:
[tex]\dfrac{dv}{dt} = 500 \ cm^3/m[/tex]
To determine; how fast does the radius change with time.
i.e.
[tex]\dfrac{dr}{dt}=???[/tex]
where r = 40 cm and the volume of sphere = [tex]\dfrac{4}{3} \pi r^2[/tex]
∴
[tex]\dfrac{dv}{dt}= \dfrac{4}{3} \pi 2(r^3) \dfrac{dr}{dt}[/tex]
[tex]500= \dfrac{4}{3} \pi \times 2(40^2) \dfrac{dr}{dt}[/tex]
[tex]500= 13404.13 \dfrac{dr}{dt}[/tex]
[tex]\dfrac{500}{13404.13} = \dfrac{dr}{dt}[/tex]
[tex]\mathbf{ \dfrac{dr}{dt} = 0.03730 \ cm/min}[/tex]
If a projectile is fired straight upward from the ground with an initial speed of 64 feet per

Star A is about 3.4 X 10^18 miles from Earth. Star B is 6.8 X 10^16 miles from Earth. Star A is how many times as far from Earth as Star B?
Answer:
Concept: Numerical Analysis
Star A is 3.4 ×10 ^18Star B is 6.8 × 10^16Hence we want how much farther Star A is from Star B.Hence Star A/Star B = 50 times fartherRATE BRAINLISTAnswer:
1/50 as far
Step-by-step explanation:
6.8 x 10[tex]^{16}[/tex] ÷ 3.4 x 10[tex]^{18}[/tex]
Rules state that you divide numbers and subtract exponents
6.8/3.4 = 2
10[tex]^{16}[/tex] ÷ 10[tex]^{18}[/tex] = [tex]10^{-2}[/tex]
whenever exponent is negative, it gets turned into a fraction with 1 as the numerator and the exponent will become positive when placed in the denominator
10^-2 = 1/10^2 which is the same as 1/100
2 multiplied by 1/100 = 1/50
Hey peeps I need help pls! Roger says that 10% of a number will always be less than 25% of any other number.
Complete one inequality to support Roger's claim and one to show that he is incorrect.
PLSSSSSSSSS HELp
Answer: [tex]0.1x-0.25y<0[/tex]
Step-by-step explanation:
Let the two numbers be x and y
10% of the first number will be;
10% of x
[tex]=\frac{10}{100} of x[/tex]
[tex]=0.1x[/tex]
25% of the other number will be ;
25% of y
[tex]0.25y[/tex]
If 10% of the first number is less than 25% of the other number, this is expressed as;
[tex]0.1x<0.25y[/tex]
[tex]0.1x-0.25y<0[/tex]
Hence the required inequality is [tex]0.1x-0.25y<0[/tex]
