Answer:

Correct cost for the cell phone monthly plan = 54.2$

Explanation:

Price for monthly plan = 58.95$

Discount = 4.75 $

New cost found out by Sam = 11.45$

Discount considered by Sam = 58.95 - 11.45 = 47.5$

So, Instead of considering discount amount of 4.75$ Sam accidentally considered 47.5$, so he got 11.45$ as new cost for the cell phone plan.

Actual cost = 58.95 - 4.75 = 54.2$

Correct cost for the cell phone monthly plan = 54.2$

c. The number of games that Ella played. (the one I think)

The answer is c the number of games that Ella played, because it says she got 16 points per game.

A.  1 : 6 = 20 : 120 = 5 : 30

1*20 : 6*20 = 20 : 120

1*5 : 6 * 5 = 5 : 30

So they are equivalent ratios

B.  1 : 6 = 4 : 18 = 6 : 36

1*4 : 6*4 = 4 : 24 which is not equivalent to 4 : 18

so, they are not equivalent ratios

C.  1 : 8 = 20 : 120 = 3 : 24

1*20 : 8*20 = 20 : 160 which is not equivalent to 20 : 120

so, they are not equivalent ratios

D.  1 : 8 = 3 : 32 = 5 : 48

1*3 : 8*3 = 3 : 24 which is not equivalent to 3 : 32

so, they are not equivalent ratios

Step-by-step explanation:

Answer:

Step-by-step explanation:

If m∠P = m∠2 then it's an isosceles triangle.

m∠M = 90°, therefore it's an isosceles right triangle.

We know, the sum of measures of angles in a triangle is equal 180°.

Therefore we have the equation:

m∠P + m∠2  + m∠M = 180°

Substitute m∠M = 90° and m∠P = m∠2 = x:

x + x + 90° = 180°      substract 90° from both sides

2x = 90°       divide both sides by 2

x = 45° → m∠P = 45°

Answer: b) 45

Step-by-step explanation:

Answer:

Subtracted 12 times a number from 72 is less than 24.

Step by step solution

Given inequality is [tex]72-12a<24[/tex]

We need to write in word.  

12a means 12 times a number “a”

72-12a means subtract 12a from 72.

72-12a<24 means result is less than 24.  

Inequality shows “Subtracted 12 times a number from 72 is less than 24”

If we solve for number “a”

-12a<24-72

-12a<-24

a>2

All the number greater than 2 satisfy the given inequality.

Answer:

A) She must have used 20% from the $40 instead of the unknown price.

B) No, because: see below explanation.

Step-by-step explanation:

X is the original price.

If $40 is 80% of x, to find 1% of the price, divide $40 by 80.

You will get $0.50 for 1%.

To find the full amount, just multiply that by 100.

0.50*100= 50.

Total: $50.

Hope this helped!

Jane's friend calculated the original price by dividing $40 by 80 and multiplying by 100. However, they made a mistake in their calculations. The correct original price before the 20% discount should be $50.

A) It seems that Jane's friend arrived at $48 by considering $40 as 80% of the original price. Since Jane received a 20% discount, it means she paid 80% of the original price. Thus, her friend might have calculated by dividing $40 by 80 and then multiplying by 100 to find the original price.

B) However, her friend's calculation is incorrect. If we indeed divide $40 by 80 and multiply by 100, we get $50, not $48. This means the original price of the item is $50.

To further illustrate this, let's consider the original price to be 'x'. If Jane received a 20% discount, she paid only 80% of 'x'. So, 0.8x = $40. Solving for 'x', we get x = $40 / 0.8 = $50.

The correct answer is:

(x,y) = (6,2)

Option A would be the correct one.

Answer:

The answer is (6, 2).

Step-by-step explanation:

This is a system of equations so we have to replace one equation in the other one, this is:

[tex]2x-y=10[/tex] Eq. 1

[tex]y=-\frac{1}{2}x+5[/tex] Eq. 2

Replacing the Eq. 2 in the Eq. 1, we have:

[tex]2x-(-\frac{1}{2}x+5)=10[/tex]

[tex]2x+\frac{1}{2}x-5=10[/tex]

[tex]2.5x=10+5[/tex]

[tex]x=\frac{15}{2.5}[/tex]

[tex]x=6[/tex]

Now we have that x=6, we can replace it in the Eq. 2:

[tex]y=-\frac{1}{2} *6+5\\y=-3+5\\y=2[/tex]

Now y=2

From the above we have that the answer is (6, 2) expressed in Cartesian coordinates.

The coefficient in the expression x/3 + 7 is 1/3, as the variable x is being divided by 3, indicating an implied multiplication of 1/3 times x.

In the expression x/3 + 7, the term x/3 has a coefficient which is the number multiplying the variable x. In this case, the coefficient is 1/3 because x can be thought of as 1x and it is being divided by 3, so the coefficient for x is actually 1/3. The number 7 in the expression is a constant and not a coefficient because it does not multiply a variable.

To find a coefficient, you generally look for the number that is directly multiplied by the variable. In the given expression, since there is a division by 3, we treat 1/3 as the coefficient, which is an implied multiplication by x. Therefore, the coefficient of the variable x in the expression x/3 + 7 is 1/3.

Answer:

a) the no of coupons used at a super market cannot be normal as the no of coupons will not be symmetrical about the mean.  In other words, the no of coupons will be increasing and hence curve cannot be bell shaped as in normal.  So not normal

2) The weights of pumpkins that are delivered to a supermarket will be normal provided the number of pumpkins is large.  This is because of central limit theorem that the average weight of pumpkin will follow a normal distribution when sample size becomes large.

3) This is a discrete distribution because no of raisins is countable and hence cannot follow a normal distribution.  Normal distribution is meant for only continuous variables.

You bought 555 apples and 444 oranges and your friend bought 555 apples and 555 oranges. He bought 555-444=111 oranges more than you bought.

You paid $10, he paid $11, then he paid $1 more than you paid.

This means that 111 oranges cost $1.

Thus, 444 oranges cost $4 and 555 apples cost $10-$4=$6.

1. If 111 oranges cost $1, then 1 orange cost [tex]\$\dfrac{1}{111} .[/tex]

2. If 555 apples cost $6, then 1 apple cost [tex]\$\dfrac{6}{555}=\dfrac{2}{185}.[/tex]

Answer:

Each apple costs $1.20 and each orange costs $1.

Step-by-step explanation:

Let x represent the number of apples and y represent the number of oranges.

For the fruit you bought, 5 apples and 4 oranges, we have 5x+4y.  This costs $10.  This gives us the equation

5x+4y = 10

For the fruit your friend bought, 5 apples and 5 oranges, we have 5x+5y.  This costs $11.  This gives us the equation

5x+5y = 11

Together we have the system

[tex]\left \{ {{5x+4y=10} \atop {5x+5y=11}} \right.[/tex]

We will eliminate x by subtracting the bottom equation from the top:

[tex]\left \{ {{5x+4y=10} \atop {-(5x+5y=11)}} \right. \\\\-1y = -1[/tex]

Divide both sides by -1:

-1y/-1 = -1/-1

y = 1

Each orange costs $1.

Substitute this into the first equation:

5x+4(1) = 10

5x+4 = 10

Subtract 4 from each side:

5x+4-4 = 10-4

5x = 6

Divide both sides by 5:

5x/5 = 6/5

x = 1.2

Each apple costs $1.20.

In step 2, multiply what is inside the parentheses by 7 (distributive property):

7 * x = 7x

7 * 3 = 21

In step 3, subtract -7x on both sides of the equation. (Property of subtraction of equality)

Then -7x + 4x = -3x

7x-7x + 21 = 21

In step 4, both sides of the equation are divided by -3.

So (owned by the equality division)

-3x / -3 = x

-21 / -3 = 7

Remember that the division of equal signs results in a positive number.

4x = 7(x-3)                  Given equation

4x = 7x - 21               7 is distributed inside the parenthesis . So the property used here

                                     is distributive property                

-3x = -21                    7x is subtracted from both sides. 4x-7x is -3x. So the property used

                                   here is subtraction property of equality.

x = 7                         -3 is divided on both sides.  -21/3 is 7. So the property used

                                   here is division property of equality.

Answer:

3 units bruh

Step-by-step explanation:

The length of the segment AB is 3 unit.

According to a property of circles, when a line passes through the center of a circle and is perpendicular to a chord, it divides the chord into two equal parts, essentially bisecting it.

We have,

Chord AC = 6 units

Now, we know that when the diameter is perpendicular to the chord bisect the chord and arc

Then, AB = CB

Thus, the length of the segment AB will be:

AC = AB + CB

6 = x + x

2x = 6

x= 3

AB = 3 unit
