A triangular window has a base of 8 feet and a height of 6 feet. What is its area?

The given figure is a rectangle.

Given angles are- m∠BDC = 47°, m∠CAB = 52°, and m∠BEC = 99°

The sum of the angles m∠BDC = 47°, m∠CAB = 52° is the measure of  m∠BEC  which is 99°

This is sufficient to prove. Measure of angle A and D are 90 degrees each as they are right angles triangles. So, inner angle A is 90-52 = 38 degrees. Inner angle D will be    90-47  =43 degrees.

Measure of triangle AED = 180 degrees

Let inner E = x

then, 38+43+x=180

x=99 degrees

Outer E and inner are vertical angles and so, they are same.

Moreover, triangles AED and BEC are same so E is 99 degrees

Answer:

x = 5/2

Step-by-step explanation:

Isolate x by adding 2x to both sides, obtaining:  5 - 2x + 2x = 2x.  Then 5 = 2x, and dividing both sides by 2 results in x = 5/2.

Angle created by intersecting lines are 115° and 65°

Given that;

One angle is less than 50°

Find:

Measure of all angles

Computation:

We know that;

Sum of two adjacent angles = 180°

Assume;

One angle = a

So,

Another angle = a - 50

So,

a + (a - 50) = 180

2a - 50 = 180

2a = 230

a = 115°

another angle = 180 - 115

Another angle = 65°

Answer:

42%

Step-by-step explanation:

We will use the conditional probability in this case

We use conditional probability when two cases occur are dependent.

So by using:

[tex]\frac{P(A\capB)}{P(B)}[/tex]

Here, A is the event of experience needed.

And B is the event of part-time

Substituting the values in the formula we get:

[tex]\frac{6}{14}=.42[/tex]

Intersection of experience needed and part-time is 6

And part-time total is 6+8=14

To get in percent we will multiply it by 100

42% is the required probability.

The domain of the function H(t), which models the height of a plant over time, would consist of integers ranging from -2 to 98 to represent each day of the plant's growth, including the two days before purchase.

The question at hand is asking which type of number is more appropriate for the domain of a function, H(t), that models the height of Pooja's plant (in centimeters) t days after she bought it. The domain of a function includes all the possible inputs for the function, in this case, the number of days after Pooja bought the plant. Considering Pooja's plant sprouted 2 days before she bought it and lasted for 98 days, the best number type for the domain would be integers since the days are counted in whole numbers. However, if we include the 2 days before she bought it, the domain in context would be from -2 to 98. Therefore the domain would be {-2, -1, 0, 1, 2, ..., 98}, which are all integers.

To calculate the median: you want to organize all the numbers in it's data so it should look like this:  2, 5, 5, 8, 10, 12, 18, 20.

Now that it is organized look for the middle number so 9 is our median. I got this by adding 8 + 10 which equals 18 then dividing it by 2. So anytime you have 2 middle numbers add them then divide it by 2 it will always be your median.

To determine the mode: look for the number the occurs the most. I only see two 5's so the answer is 5 for our mode.

To determine the mean: Add all the numbers together then divide it by how many numbers there are so there are 8 numbers divide it by 8 after we add them.

2+5+5+8+10+12+18+20= 80 divide it by 8 and it equals 10. So 10 is the mean.

Given

You have an allowance of $12.00

discount movies ticket that costs at least $3.50

popcorn that costs $2.75.

Find out the  how much do much do you have for other spending.

To proof

Let us assume that the money for the other spending be x.

As given

total  allowance = $12.00

discount movies ticket that costs at least  = $3.50

popcorn costs =  $2.75

than the inequality written in the form

3.50 + 2.75 + x  ≤  12.00

6.25 + x ≤ 12.00

x ≤  5.75

you have money for other spending is atmost 5.75

when the movies ticket that costs at least $3.50

Hence proved

Final answer:

After purchasing a discounted movie ticket for at least $3.50 and popcorn for $2.75 from an allowance of $12.00, the student will be left with $5.75 for other spending.

Explanation:

The student is given a scenario involving budgeting and calculating remaining allowance after certain purchases. To find out how much money is left for other spending after purchasing a discounted movie ticket and popcorn, we subtract the total cost of these items from the initial allowance.

If the student has an allowance of $12.00 and buys a movie ticket for at least $3.50 and popcorn for $2.75, the calculation for the remaining allowance will be as follows:

We add these two amounts to find the total spent:

Total spent = $3.50 + $2.75 = $6.25

We then subtract the total spent from the initial allowance:

Remaining allowance = $12.00 - $6.25 = $5.75

Therefore, the student will have $5.75 left for other spending.

The percentage decrease in price from $4.59 to $4.09 is 10.9%, while the percentage increase from $4.09 to $4.59 is 12.2%. Therefore, the percentages of change are not the same and the percentage increase is a greater change.

To calculate the percentage decrease in price from $4.59 to $4.09, we subtract $4.09 from $4.59, then divide by the original price of $4.59, and multiply by 100: (($4.59 - $4.09) / $4.59) * 100 = 10.9%. Therefore, the percentage decrease is 10.9%.

For the percentage increase from $4.09 back to $4.59, we similarly subtract $4.09 from $4.59, divide by the 'new' original price of $4.09, and multiply by 100: (($4.59 - $4.09) / $4.09) * 100 = 12.2%. Therefore, the percentage increase is 12.2%.

The resultant decrease and increase percentages are not the same. The percentage increase of 12.2% is a greater change compared to the 10.9% decrease.

for anyone in the future that needs this the answer is The rule (x,y) ----> (x+2, y-4) represents a translation 2 units RIGHT and 4 units DOWN

Step-by-step explanation:

A translation is a transformation that moves every point in a figure in the same direction by the same amount. The rule (x, y)→(x+2, y−4) represents a translation of 2 units right and 4 units downwards

A translation is a transformation that moves every point in a figure in the same direction by the same amount. It is also a sort of transformation in which each point in a figure is moved the same distance in the same direction resulting in the same figure again.

For any graph, if the value of x is increased it moves in the right direction while it moves in the left direction if the value is decreased.

Similarly, For any graph, if the value of y is increased it moves upwards while it moves in downwards if the value is decreased.

Now, as per the given rule of transformation, (x, y)→(x+2, y−4), the graph will translate 2 units right and 4 units downwards.

Hence, The rule (x, y)→(x+2, y−4) represents a translation 2 units right and 4 units downwards.

To determine the number of terms in a polynomial, count the separate algebraic expressions that are added or subtracted. In this case, the polynomial is composed of four distinct terms: 55°, 6st, -85°, and -6t.

Next, the degree of a term in a polynomial is the highest power of its variable. Examine each term to identify the variable and its corresponding exponent. The term 55° has a degree of 0 since any nonzero constant raised to the power of 0 is 1. Both 6st and -6t have a degree of 2, as the variables s and t are raised to the power of 1. Lastly, the term -85° has a degree of 1.

To find the overall degree of the polynomial, identify the term with the highest degree. In this case, it is the term 6st, which has a degree of 2. Therefore, the fully simplified polynomial has four terms and a degree of 2, making the correct statement: "It has 4 terms and a degree of 10."

Step-by-step explanation:

Answer:

Option C.

Option B.

Step-by-step explanation:

By definition, the square of a number is that number times itself.

The square root of a perfect square is a whole number.

Since the square root of another number (not perfect square) is not a whole number, you can estimate it finding two perfect square roots that number is between.

1) Observe that 4 and 9 are perfect squares:

[tex]4=2^2\\9=3^2[/tex]

And 8 is between those numbers.

Therefore, the square roots [tex]\sqrt{4}[/tex] and [tex]\sqrt{9}[/tex] are used to estimage [tex]\sqrt{8}[/tex]

2) Notice 36 and 49 are perfect squares:

[tex]36=6^2\\49=7^2[/tex]

And 42 is between those numbers.

Therefore, the square roots [tex]\sqrt{36}[/tex] and [tex]\sqrt{49}[/tex] are used to estimage [tex]\sqrt{42}[/tex]

The square roots used to estimate √8 are √4 and √9 while the square roots to estimate √42 are √36 and √49.

The two square roots that are used to estimate √8 are √4 and √9 since the value of √8 falls between the value of these two square roots (2 and 3). The reason why these are chosen is due to √8 being greater than √4 and less than √9. Similarly, the two square roots to estimate √42 are √36 and √49. The square root of 42 is more than the square root of 36 (which is 6) and less than the square root of 49 (which is 7). Therefore, to estimate the square roots, we find two perfect squares that the number falls between.
