Answer:

A. $1.75 + $0.25x ≤ $15

Step-by-step explanation:

This is because if Eddie has 15 dollars, he can only use 15 dollars or less. So in this case, the inequality would have to be less than or equal to 15 dollars.  

Eddie travel $1.75 + $0.25x ≤ $15 miles when he has $15 to spend.

Option A is the correct option.

Here,

Amount of flat fee of taxi cab = $1.75

Amount of charge for each miles = $0.25

The amount Eddie has to spent = $15

We have to find inequality relationship.

What is inequality?

The relationship between two values that are not equal is defined by inequalities.

Now,

Amount of flat fee of taxi cab = $1.75

Amount of charge for each miles = $0.25

The amount Eddie has to spent = $15

Let Eddie travel x miles.

Therefore, the total charge of taxi cab = $1.75 + 0.25x

And this amount should not exceed the $15 as it is the only amount Eddie has.

Hence the inequality relationship be,

$1.75 + 0.25x ≤ $15.

Option A is the correct option.

Answer: 26

Step-by-step explanation:

Two Angles are Complementary when they add up to 90 degrees (a Right Angle). Then

∠A + ∠B = 90

∠A =90- ∠B

∠A  = 26

Answer:

$29.50

Step-by-step explanation:

The price that Rob paid includes a 15% discount.  This means that Rob paid 85% of the original price.

100% - 15% = 85%

Divide the price Rob paid by the percentage the price is of the total.

85% = 0.85

50.15/0.85 = 59

Now, divide the total price by 2 so that you can find the price of one pair of jeans.

59/2 = 29.50

The price of one pair of jeans is $29.50

Answer:

6 hot dogs package assuming she's buying a single package to contains 10 package or approximately 8 rolls if she buys the 8 package containing above 60 rolls of hot dogs.

In my opinion, she needs at least 8 package of hot dog rolls to make hot dogs for her guests.

Step-by-step explanation:

Hello,

There are typically 10 hot dogs in a single package. However some may contain 8 hot dogs rolls in a single pack so we'll solve for both in case which ever one she decides to buy.

My teacher is expecting 30 guests coming to the party and each 1 one them wants to eat 2 hot dogs.

To solve this question, we would first of all know the total number of hot dogs they'll probably eat at the party.

2 hot dogs = 1 person

y hot dogs = 30 people

y = (30 × 2) / 1

y = 60 hot dog.

Therefore, the guest would most likely consume at least 60 hot dogs at the party.

However, in a single hot dog package, it contains 10 hot dogs in it.

Now we'll have to find out the total number of hot dogs package my teacher needs to buy to prepare the hot dogs for her guests.

To do that, we'll have to divide the total number of hot dogs expected to be consumed by the total number of hot dogs in one package.

Number of package = total number of hot dogs expected to be consumed / total number of hot dogs in one package.

Number of package she needs = 60 / 10

Number of package she needs = 6

Therefore, my teacher requires 6 hot dog package.

But some hot dogs comes in 8 rolls per package

Using the same method above,

Number of rolls she needs = 60 / 8

Number of rolls she needs = 7.5 approximately 8 rolls

Answer:

7.855

Step-by-step explanation:

A=pi*r^2=3.142*5^2=3.142*25=7.855

The value of A = 7.855 units.

The area of a circle is π multiplied by the square of the radius. The area of a circle, (A) when the radius 'r' is given is πr2. π is approximately  3.142

Here, given that,

r= 5 units

Then, A=pi*r^2

            =3.142*5^2

            =3.142*25

            =7.855

hence, the value of A = 7.855 units.

Answer:

£151.20

Step-by-step explanation:

20%= 100%divided by 5

To find 100% from 20% you x by 5

so you times 30.24 by 5

30.24x 5 = 151.2

So the answer is £151.20

interest percentage rate would be 1.6754%

The interest rate for the account is 1.68%

The interest rate is the amount a lender charges a borrower and is a percentage of the principal the amount loaned.

Given that,

Sue invests £9000 in an account for one year.

She pays £30.24 at a rate of 20%

So, 20% of the interest = £30.24

Let the interest be x,

X0.2 = 30.24

X = £151.2

The total interest was = £ 151.2

The rate R at which generated this interest =

R = (100 × 151.2)/(1 × 9000)

R = 15120/9000

R = 1.68%

Hence, the interest rate = 1.68%

The function is y = 40 * 2^(x/2)

The graph is in the image attached

Step-by-step explanation:

The function that models this growth is an exponencial function, that can be described with the following equation:

y = a * b^(x/n)

Where a is the inicial value, b is the rate of growth, x is the time and n is the relation between the time and the rate (the rate occurs for every two hours, so n = 2).

Then, using a = 40, r = 2 and n = 2, we have:

y = 40 * 2^(x/2)

If we plot this function, we have the graph shown in the image attached,

It is an exponencial graph, where the value of y increases very fast in relation to the increase of x.

Answer:

she spent £270.

Step-by-step explanation:

First, let us define what a ratio of 9:6 means.

when you have a ratio such as this, you have to add both ratios first:

9+6 = 15

This means that out of every 15 parts, the ratio of the sharing is 9 parts to 6 parts.

Now let us solve the problem

Savings to spending = 9:6

if total amount = m

ratio saved = 9/15 × m

ratio spent = 6/15 × m

Now total amount (m) = £450

∴ ratio saved = 9/15 × 450 = 4050/15 = £270

Therefore she spent £270.

To calculate the amount saved, we simply subtract 270 from 450, or we use (6/15 × 450). You can try it out to see if you get the same answer, which is she spent £180

Answer:

x= 5t - a

Step-by-step explanation:

6x + a = 5(x+t)

If you expand 5(x+t), you will get 5x + 5t

i.e. 6x + a = 5x + 5t

Add the additive inverse of 5x to both sides (The additive inverse of 5x is -5x)

i.e. 6x + a - 5x = 5x + 5t - 5x

     x + a = 5t

Then, add the additive inverse of "a" to both sides (The additive inverse of a is -a)

i.e. x + a - a = 5t - a

x = 5t - a

Reflection across x = -1

The simplest way to calculate the new coordinates is to draw x = -1, count how many units away the point is from x = -1, then count the same number of units from x = -1 in the OPPOSITE direction to find the reflection. (see attachment)

J = (0, 0) is 1 unit to the right of x = -1

J' = (-2, 0) is 1 unit to the left of x = -1

K = (1, 4) is 2 units to the right of x = -1

K' = (-3, 4) is 2 units to the left of x = -1

L = (3, 3) is 4 units to the right of x = -1

L' = (-5, 3) is 4 units to the left of x = -1

Reflection across x-axis

Change the sign of the y-value:  (x, y) → (x, -y)

J' = (-2, 0)           J'' = (-2, 0)

K' = (-3, 4)           K'' = (-3, -4)  

L' = (-5, 3)            L' = (-5, -3)
