andy incorrectly solved an equation and showed his work.

step 1: 5 (2r + 5) = 100
Step 2: 10x + 5 = 100
Step 3: 10x = 95
Step 4: x = 9.5

What error did Andy make, and what is the correct solution to his problem?

a: Andy made an error with the distributive property in step 2, x = 7.5

b: Andy made an error with the distributive property in step 2, x= 12.5

c: Andy made an error with the associative property in step 2, x= 7.5

d: Andy made an error with the subtraction property in step 2, x= 12.5​

Answers

Answer 1
the answer is A. this is because when andy distributed the 5 from the outside of the parenthesis to the inside, he multiplied 5•5 to equal 10, and 5•5 is 25.

The driver of a car traveling at 60 ft/sec suddenly applies the brakes. The position of the car is s(t) = 50t - 2t2, t seconds after the driver applies the brakes. How many seconds after the driver applies the brakes does the car come to a stop? (4 points)

Answers

Answer:

t=12.5s

Step-by-step explanation:

s(t) = 50t - 2t^2

v(t) = 50 - 4t

a(t) = -4

When v(t) = 0, the car stops.

v = u +at

0 = 50 + (-4)t

t = 12.5



In the given figure lines AB and CD intersect
ato. If angle AOC + angle BOE = 70 and angle DOB
=40°, find angle BOE and reflex angle EOC.

Answers

Answer:

reflex angle EOC = 250°

Step-by-step explanation:

reflex angle EOC

= angle COA + angle DOA + angle DOB + angle BOE

angle DOB = 40° (given)

angle DOB + angle DOA = 180° (linear pair)

angle DOA = 180° - 40°

angle DOA = 140°

angle COA + angle DOA = 180° (linear pair)

angle COA = 180° - 140°

angle COA = 40°

angle COA + angle BOE = 70° (given)

angle BOE = 70° - 40°

angle BOE = 30°

Now,

we have,

reflex angle EOC = 40° + 140° + 40° + 30°

= 250°

Find the radius of a circle using the Pythagorean theorem, given that the center is at (1, 5) and the point (5, 1) lies on the circle. 32−−√ units 12−−√ units 72−−√ units 50−−√ units

Answers

Given :

Center of circle, C = ( 1 , 5 )

Point on circle, P = ( 5 , 1 )

To Find :

The radius of a circle.

Solution :

We know, radius of circle is the distance between center and point of circle.

Distance between two points A(p,q) and B(r,s) is given by :

[tex]D = \sqrt{(p-r)^2+(q-s)^2}[/tex]

So, distance between the points (1, 5) and (5, 1) is :

[tex]D = \sqrt{(1-5)^2+(5-1)^2}\\\\D = 5.66 \ units[/tex]

Therefore, radius of circle is 5.66 units.

Hence, this is the required solution.

There are 6 people in George's family. How much did George's mom pay for tickets? Show how you found your solution.

Answers

Answer:

$75

Step-by-step explanation:

To find out how much George's mom paid for the 6 tickets, first find the unit rate, that is cost per ticket.

The unit rate/constant of proportionality between cost of tickets (y) and number of tickets (x) can be calculated using the coordinates of any points on the graph.

Using (4, 50), this means that 4 tickets cost $50.

Unit rate/constant of proportionality = y/x = 50/4 = 12.5

This means a ticket costs $12.5.

Therefore, 6 tickets would cost:

6 tickets × $12.5 = $75.

1. Andrew went to FYE to buy music for the band. He spent a total of $112 on 14 music purchases. one Music CDs were on sale for $10 and cassettes were on sale for $3. How much did Andrew pay for each music CD and each cassette tape? Enter your one-sentence interpretation in the space below.​

Answers

Answer:

Total Money spent on Music CDs = 10 [tex]\times[/tex] 10 = $100

Total Money spent on Cassette tapes = 4 [tex]\times[/tex] 3 = $12

Step-by-step explanation:

Given that:

Total money spent = $112

Number of music purchases = 14

Cost of one Music CD = $10

Cost of one cassette = $3

To find:

How much money was paid for each music CD and each cassette.

Solution:

Let the number of Music CDs purchased = [tex]x[/tex]

Money spent on Music CDs = [tex]\$10\times x[/tex]

Then the number of cassette tapes purchased = [tex]14-x[/tex]

Money spent on cassette tapes = [tex]\$3\times (14-x)[/tex]

As per the question statement:

[tex]10x+3(14-x)=112\\\Rightarrow 10x+42-3x=112\\\Rightarrow 7x=112-42\\\Rightarrow 7x=70\\\Rightarrow x =10[/tex]

Therefore, number of Music CDs purchased = 10

Total Money spent on Music CDs = 10 [tex]\times[/tex] 10 = $100

And number of cassette tapes purchased = 14 - 10 = 4

Total Money spent on Cassette tapes = 4 [tex]\times[/tex] 3 = $12

The coordinates of mage of L(5, 10) will be: (11, 3)

So, the 4th (last) option is correct.

Step-by-step explanation:

As we know that Translation means how much a point is moved to the left/right and up/down.

Given the translation maps the point J(1, 4) onto K(7, -3).

As the x-coordinate of the image point K(7, -3) is 7 which is 6 units right to the original point J(1, 4).

Also, the y-coordinate of the image point K(7, -3) is -3 which is 7 units down to the original point J(1, 4)

so it means the translation basically implies that

(x, y) → (x + 6, y - 7)

Hence, the coordinate of the image of L(5, 10) can also be determined by

using the same rule.

(x, y) → (5 + 6, 10 - 7) = (11, 3)

Therefore,  the coordinates of mage of L(5, 10) will be: (11, 3)

So, the 4th (last) option is correct.

so  49.8004 is what it is 0.001 left. 1  x or divide it stay the same

exp: 1[tex]1\sqrt{2}[/tex]

Explanation:

Whenever you divide by a fraction, you multiply by the reciprocal of that fraction, so 49.8004 / 0.001 would be 49.8004 / 1/1000, which would be 49.8004 * 1000/1, which is 49,800.4.

If you think about it, the problem translated into words is "How many 0.001's fit into 49.8004", which is a big number, because a lot of 0.001's can fit inside 49.8004.
