AB is a straight line. Work out the size of angle k
Answer:
35°
Step-by-step explanation:
180 degrees is the total sum of the angles in a triangle.
180° - 130° = 50°
180° - 85° = 95°
50° + 95° = 145°
180° - 145° = 35°

TOLL ROAD Mr. Espinoza randomly chooses one of five toll booths when
entering a toll road when driving to work. What is the probability he will
select the middle toll booth on Monday and Tuesday?
Answer: Assuming that the selection of the toll booth is a random and independent event, the probability that Mr. Espinoza chooses the middle toll booth on Monday is 1/5 (or 20%), since there are five total toll booths and the middle booth is one of those options. Similarly, the probability that he chooses the middle booth on Tuesday is also 1/5 (or 20%).
To find the probability that he chooses the middle booth on Monday and Tuesday, we can multiply the probabilities of each event.
Probability of selecting middle booth on Monday AND selecting middle booth on Tuesday = (1/5) * (1/5) = 1/25 = 0.04 or 4%
So, Mr. Espinoza will select the middle toll booth on Monday and Tuesday with a probability of 4%. This means that the chance that both events will happen is low and quite rare, but not impossible.

Find the lengths of the diagonals of rectangle WXYZ.
WY = 14x + 10
XZ = 11x + 22
The length of each diagonal is
units.
The length of each diagonal is √(196x^2 + 816x + 324) units.
What is the formula for diagonal length?The diagonal of a rectangle can be estimated using the hypotenuse formula, such as using the Pythagorean theorem calculator.
WX^2 = WY^2 + XZ^2
Given that WY = 14x + 10 and XZ = 11x + 22, we can substitute those values in the equation:
WX^2 = (14x + 10)^2 + (11x + 22)^2
WX^2 = 196x^2 + 816x + 324
WX = √(196x^2 + 816x + 324)
The same goes for the other diagonal, WZ.
WZ = √(196x^2 + 816x + 324)
So, the length of each diagonal is √(196x^2 + 816x + 324) units.

$\%$
b. Show how you could use a polynomial to model the possible gene combinations of the offspring.
The gene combinations could be modeled by the polynomial
Using Punnett square we know that 25%of the possible gene combinations result in albino coloring.
What is Punnett square?The genotypes of a specific cross or breeding experiment are predicted using the Punnett square, a square diagram.
It bears Reginald C. Punnett's name, who developed the method in 1905.
Biologists use the figure to calculate the likelihood that a child will have a specific genotype.
So, there is only one gene combination that could result in albinism.
4 different gene pairings are possible.

For a given recipe, 9 cups of flour are mixed with 18 cups of sugar. How many cups of sugar should be used if 15 cups of flour are used?
Answer:
7.5 cups of sugar
Step-by-step explanation:
You should use proportions to find the answer.
9/18 = 15/x
Cross multiply:
9*15 = 135
135/18 = 7.5
Because half of 18 is 9, you just need to find half of 15, which is 7.5.

what is proportion ?The term "proportionate" refers to relationships that always have the same ratio. For instance, the average number of apples per tree influences how many trees there are in an orchard and how many fruits there are in a harvest of apples. A linear relationship between two numbers or variables is referred to in mathematics as being proportionate. In the same way as the first quantity doubles, so does the other. The other decreases as well when one of the variables is reduced to 1/100th of its previous value. When two quantities are proportional, it means that when one rises, the other rises as well and that the ratio between the two quantities is constant at all values. As an example, consider a circle's diameter and circumference.

Judiyah is the proud new owner of a chair making business. She makes custom wood chairs. She sells her custom chairs for
$150. The cost of rent and the expensive saws and equipment she bought add up to about $50 a chair. The wood she uses is
standard wood and the materials to make one chair cost about $30. She pays one worker to help her move the chairs into people's
home. Everytime she sells a chair, she pays this worker
$10 for the hour of work to transport the homemade chair.
What is judiyah’s profit ?
Answer:
$60
Step-by-step explanation:
Profit = revenue - total cost
cost is total expenses incurred in running the business
total cost = cost of rent and the expensive saws and equipment + cost of wood + amount paid to worker
50 + 30 + 10 = 90
revenue is the amount earned from selling the chairs. it is equal to 150
Profit = 150 - 90 = 60

Tierra is making steps for a doll house. She has cut a piece of wood that measures 1. 5 centimeters wide and 30 centimeters long. Each step will measure 15 millimeters by 4 millimeters. She will make 21 steps for her doll house. Which are the dimensions of the wood that remains after Tierra finishes making the 21 steps?
The dimensions of the wood that remains after Tierra finishes making the 21 steps is 1.185 cm by 21.6 cm
In Mathematics, dimensions are referred to as measures of size such as length, width, and height of an object or a shape.
A square has sides of equal dimensions.
A rectangle has length and width as its dimensions that define the area of a rectangle.
Also, dimension is used widely to term the figure as one-dimensional, two-dimensional or three-dimensional.
Wood = 1.5 cm by 30 cm
Each cut = .15 mm by 4 mm
Steps = 21
The remaining dimension is calculated as:
Remaining = 1.5 cm - 21 * .15 mm by 30 cm - 21 * 4 mm
Express mm as cm
Remaining = 1.5 cm - 21 * .015 cm by 30 cm - 21 * 0.4 cm
Evaluate the difference
Remaining = 1.185 cm by 21.6 cm
Hence, the dimensions of the wood that remains after Tierra finishes making the 21 steps is 1.185 cm by 21.6 cm

If star a is closer to us than star b, then star a's stellar parallax is __________.
O Larger than that of star B
O Larger than that of star A
O Smaller than that of star B
O Smaller than that of star A
If star A is closer to us than star B, then Star A's parallax angle is: Larger than that of Star B.
Hence, option (A) is correct choice.
The parallax of a star at a distance of 10 parsecs would be 0.1′′ since parallax is inversely proportional to distance. The parallax of Proxima Centauri, a star in the triple system of Alpha Centauri, is 0.76813′′, indicating that it is 4.24 light-years away from Earth at a distance of 1/0.76813, or 1.302 parsecs.
The apparent shift in an object's location caused by a change in the observer position is known as parallax. This apparent shift is measured (in arc seconds) is reversed to provide the distance from the background stars (in parsecs).
The definition of an object's absolute magnitude is the apparent magnitude the object would have if it were observed at a distance of precisely 10 parsecs (32.6 light-years), without light extinction.

A standard deck of 52 cards contains four suits: clubs, spades, hearts, and diamonds. Each deck contains an equal number of cards in each suit. Rochelle chooses a card from the deck, records the suit, and replaces the card. Her results are shown in the table. Cards Suit Observed Frequency Clubs 29 Spades 13 Hearts 15 Diamonds 23 How does the experimental probability of choosing a heart compare with the theoretical probability of choosing a heart
The theoretical likelihood of selecting a heart is 1/16 times higher than the actual likelihood.
In the given question, we have to find the experimental probability of choosing a heart compare with the theoretical probability of choosing a heart.
We are aware that a deck's total number of cards= 52
Total number of hearts = 13
Then the theoretical probability of getting a heart = Number of cards have hearts/Total cards
Then the theoretical probability of getting a heart = 13/52
Then the theoretical probability of getting a heart = 1/4
Then the theoretical probability of getting a heart = 0.25
Cards chosen by Rochelle : Clubs 29, Spades 13, Hearts 15, Diamonds 23
Total cards = 80
The experimental likelihood of experiencing a heart attack = Number of cards have hearts/Total cards
The experimental likelihood of experiencing a heart attack = 15/80
The experimental likelihood of experiencing a heart attack = 3/16
The experimental likelihood of experiencing a heart attack = 0.185
Since, 0.25 > 0.1875 so, Theoretical probability > Experimental probability
and,
Theoretical probability = 0.25-0.1875
Theoretical probability = 0.0625
Theoretical probability = 625/10000
Theoretical probability = 1/16
Hence, the theoretical likelihood of selecting a heart is 1/16 times higher than the actual likelihood.
