Ibrahim has 33 more stickers than Rosie

An equation is an expression used to show the relationship between two or more variable and numbers.

Given the ratio:

Rosie: Matilda: Ibrahim = 4 : 7 : 15

Let x represent the total number of stickers

Ibrahim = (15/26)x

Matilda = (7/26)x

Given:

(15/26)x = (7/26)x  + 24

x = 78

Ibrahim = (15/26)*84 = 45

Rosie = (4/26)*84 = 12

Ibrahim has 33 (45 - 12) more stickers than Rosie

Step-by-step explanation:

yes its a right triangle

Step-by-step explanation:

The triangle inequality theorem is not followed,  no triangle can be formed.

In Geometry, a triangle is a three-sided polygon that consists of three edges and three vertices.

The triangle inequality theorem describes the relationship between the three sides of a triangle.

According to the triangle inequality theorem, the sum of any two sides must be greater or equal than the length of the third side.

Here, the sides are 4.72 yds, 6.31 yds, and 1.67 yds.

4.72 + 6.31 = 11.02  >  1.67  (theorem followed)

4.72 + 1.67 = 6.39  > 6.31    (theorem followed)

6.31 + 1.67 = 7.98 > 4.72 (theorem not followed)

Since the triangle inequality theorem is not followed,

Hence, no triangle can be formed.

Luke left out a number while putting the numbers in order. The correct answer is 16.

Numbers given are 16, 24, 12, 7, 30, 11, 22.

Let us arrange the numbers in ascending order, starting from left to right,

The correct order is 7, 11, 12, 16, 22, 24, 30.

While Joe arranged them in the following manner:

x x 16 22 24 30 (left out a number)

He got the median as the average of the middle numbers.

Joe got (16+22)/2 = 19 as answer.

The median is the middle number in a sorted, ascending, or descending, list of numbers and can be more descriptive of that data set than the average.

Since the total number of observations is odd so median will be the middle number.

So, the median is 16.

Hence, Luke left out a number while putting the numbers in order. The correct answer is 16.

Answer:

(3x^2 - 1)(3x^2 + 1)(9x^4 + 1).

Step-by-step explanation:

Using the identity for the difference of 2 squares;

a^2 - b^2 = (a - b)(a + b)  

we put a^2 = 81x^8 and b^2 = 1  giving

a = 9x^4 and b = 1, so:

81x^8 − 1 =   (9x^4 - 1)(9x^4 + 1)

Applying the difference of 2 squares to 9x^4 - 1:

= (3x^2 - 1)(3x^2 + 1)(9x^4 + 1).

Answer:

The answer is (3x^2 - 1)(3x^2 + 1)(9x^4 + 1).

Answer:

A) car 1: exponential

   car 2: linear

B) car 1: [tex]f(x)=18500(0.94)^{x-1}[/tex]

    car 2: [tex]f(x)=-1000x+19500[/tex]

C) Yes, there will be a significant difference of $1,100.40 which is approx 10% of the value of the cars after 10 years.

Step-by-step explanation:

Part A

Car 1: exponential as the projected value is not decreasing by the same amount each year

Car 2: linear as the projected value decreases by the same amount each year ($1000)

Part B

Car 1

General form of exponential function: [tex]y=ab^x[/tex]

a = initial value = 18500

b = growth factor = [tex]\dfrac{17390}{18500}=0.94[/tex]

[tex]\implies f(x)=18500(0.94)^{x-1}[/tex]

NB We have to change x to "x-1" since we are told in the table that after 1 year the car's value is 18500.

Car 2

General form of linear function:  [tex]y=mx+b[/tex]

[tex]m=\dfrac{\textsf{change in} \ y}{\textsf{change in} \ x}=\dfrac{17500-18500}{2-1}=-1000[/tex]

[tex]y-y_1=m(x-x_1)[/tex]

[tex]\implies y-17500=-1000(x-2)[/tex]

[tex]\implies f(x)=-1000x+19500[/tex]

Part C

Car 1 after 10 years: [tex]\implies f(10)=18500(0.94)^{10-1}=\$10,600.40[/tex]

Car 2 after 10 years: [tex]\implies f(10)=-1000(10)+19500=\$9,500[/tex]

Difference = 10600.40 - 9500 = 1100.40

Yes, there will be a significant difference of $1,100.40 which is approx 10% of the value of the cars after 10 years.

The time it'd take for the element to have 15 g of mass is approximately 68 min.

Step-by-step explanation:

The radioactive decay of a substance is given by the following formula:

Since the element has a half life of 12 minutes, this means that after this time the mass of the element will be half of it was originally, therefore:

Therefore the mass of the element is given by:

If the initial mass is 760 g and the final mass is 15 g, we have:

The time it'd take for the element to have 15 g of mass is approximately 68 min.

Step-by-step explanation:

Element X take 32.6 minutes to decay to 87 grams.

Mathematical expression is defined as the collection of the numbers variables and functions by using operations like addition, subtraction, multiplication, and division.

Given that;

Element X decays radioactively with a half life of 15 minutes.

And, there are 400 grams of Element X.

Now, By the given information, we can formulate;

⇒ [tex]y = x (0.5)^{t/h}[/tex]

Substitute all the values we get;

⇒ 400 = 87 × [tex](0.5)^{t/15}[/tex]

⇒ 400 / 87 =  [tex](0.5)^{t/15}[/tex]

⇒ 4.6 =  [tex](0.5)^{t/15}[/tex]

Take log both side,

⇒ ln 4.6 = t/15 (ln 0.5)

⇒ 1.52 = t/15 x 0.7

⇒ t = 32.6 minutes

Thus, Element X take 32.6 minutes to decay to 87 grams.

The experimental probability that Hilda pulled a red marble is 0.11752 or 11.752%.

Probability means possibility. It deals with the occurrence of a random event. The value of probability can only be from 0 to 1. Its basic meaning is something is likely to happen. It is the ratio of the favorable event to the total number of events.

For a class experiment, Hilda places different colored marbles in a bag. She pulls a marble at random from the bag, records its color, and then puts the marble back in the bag. She repeats this process 25 times.

The overall results are shown in the table.

Blue, Red, Yellow, Orange Frequency 6, 4, 8, 7 respectively.

P(red) will be 1/4 and P(not red) will be 3/4.

The number of trials (n) is 25.

Frequency of the red (r) = 4

Answer: $50

Step-by-step explanation:

All 12 of the televisions have extended warranties 12*30=360

Answer:

1/16

Step-by-step explanation:

Since no cards are removed between each shuffle, the chance of drawing a spade both times remains the same, meaning it is 1/4 both times. 1/4 * 1/4 =1/16

The probability of drawing two spades in two draws if the first card is returned to the deck between draws will be 1 / 16.

Probability is defined as the ratio of the number of favourable outcomes to the total number of outcomes in other words the probability is the number that shows the happening of the event.

Probability = Number of favourable outcomes / Number of samples

Given that the chance of drawing a spade from a deck of cards is 1/4. If the deck is shuffled between draws.

The probability will be calculated as,

Probability = 1 / 4 x 1/ 4

Probability = 1 / 16

Hence, the probability will be equal to 1 / 16.

Answer:

80 units²

Step-by-step explanation:

To find the area, we will need to use the formula A = b * h.

We know the height is 8 and the base is 10. We ignore the length of 11 since it is not relevant.

So what the equation would look like, when plugging in the 8 for height and 10 for base is:

A = 10 * 8 = 80 units²

So the area of the parallelogram is 80 units²

The area of a parallelogram is the product of the length of the parallel side and the distance between the parallel sides. Then the area of the parallelogram is 80 square units.

It is a polygon that has four sides. The sum of the internal angle is 360 degrees. In a parallelogram, opposite sides are parallel.

The area of the parallelogram will be given as

Area = bh

Where b is the length of the parallel side and h is the distance between the parallel sides.

Area = 10 × 8

Area = 80

The area of the parallelogram is 80 square units.
