Answer:

The area is 6\(\sqrt{45}\)

Step-by-step explanation:

Using the Pythagorean Theorem, you'll get that half the base is \(\sqrt{45}\), so the entire base is \(2\sqrt{45}\). Multiply that by the height and divide by two, you'll get that the area of this triangle is 6

The total number of workers that were studied can be found to be 139,340,000.

The percent of workers unemployed would be 5. 4 %.

Percentage of unemployed men is 5. 6 % and unemployed women is 5. 1%.

Number of employed workers :

= 74,624,000 + 64, 716, 000

= 139,340,000

Percentage unemployed :

= ( 4, 209,000 + 3,314,000 ) / 139,340,000

= 5. 4 %

Percentage of unemployed men :

= 4,209,000 / 74,624,000

= 5.6 %

Percentage of unemployed women:

= 3,314,000 / 64, 716, 000

= 5. 1 %

Answer:

To find the length of AB, we can use the property that two tangents to a circle from the same external point are equal. This means that AB = AD. Substituting the given values, we get:

8x = x + 9

Solving for x, we get:

x = 1.5

Therefore, AB = 8x = 8(1.5) = 12.

To check our answer, we can use the Pythagorean theorem on triangle ABD, since AB is perpendicular to BD at the point of tangency. We have:

AB^2 + BD^2 = AD^2

Substituting the values, we get:

12^2 + BD^2 = (1.5 + 9)^2

Simplifying, we get:

BD^2 = 56.25

Taking the square root of both sides, we get:

BD = 7.5

Hence, the length of AB is 12 and the length of BD is 7.5.

Using proportions, we can say that 42 models of 100 are needed to model 4200.

Ratio and fractions are the main bases on which proportion is explained. A fraction is written as a/b, while a ratio is represented as a:b, and a proportion states that two ratios are equal. In this case, a and b can be any two integers. The ratio and proportion are important building blocks for understanding the numerous ideas in science and mathematics.

In the question, we are asked for the number of models of 100 we need to model 4200.

The given problem can be shown as a proportion with the ratio of the number of models of 100, to the model.

We know that 1 model of 100 makes a model 100.

We assume that n models of 100 makes a model 4200.

By proportion, we can show that:

n/4200 = 1/100,

or, n = 4200/100,

or, n = 42.

Thus, using proportions, we can say that 42 models of 100 are needed to model 4200.

Answer:

{-2/3, 10/3}

Step-by-step explanation:

Let's solve your equation step-by-step.

|3x−4|=6

Solve Absolute Value.

|3x−4|=6

We know either3x−4=6or3x−4=−6

3x−4=6(Possibility 1)

3x−4+4=6+4(Add 4 to both sides)

3x=10

3x/3 = 10/3

(Divide both sides by 3)

x=10/3

3x−4=−6(Possibility 2)

3x−4+4=−6+4(Add 4 to both sides)

3x=−2

3x/3 = −2/3

(Divide both sides by 3)

x= −2/3

Answer:

1, 3, 5, 7, 9, 11, 13

Step-by-step explanation:

Answer:

The answer should be: 9

Step-by-step explanation:

The terms in the sequence are said to increase by a common difference, d. For example: 3, 5, 7, 9, 11, is an arithmetic progression where d = 2. The nth term of this sequence is 2n + 1.

Answer:

x + x - 45 = 90

2x - 45 = 90

2x = 135

x = 67.5, so x - 45 = 22.5

The other two angles measure 22.5° and 67.5°.

there exists an integer that is greater than 5 and whose square is smaller than 40, express as a mathematical quantifiers ∃x∈ℤ: x > 5 ∧ x² < 40

1.  Start by writing down the equation: x² < 40

2.  Take the square root of both sides of the equation to isolate the variable x: √x² < √40

3.  Simplify both sides of the equation: x < √40

4.  Check that the result makes sense: x < 6.3

5.  Take the integer part of the result: x < 6

6.  Since the requirement is that x is greater than 5, the answer is x = 6.

We start by writing the equation x² < 40 and then take the square root of both sides to get x < √40. We check that the result is reasonable and then take the integer part of the result to get x < 6. Since the requirement is that x is greater than 5, the answer is x = 6. To confirm, we can calculate that x² = 36 which is smaller than 40, and indeed, 6 is greater than 5. Therefore, the integer that is greater than 5 and whose square is smaller than 40 is 6. This can be expressed mathematically as ∃x∈ℤ: x > 5 ∧ x² < 40 which translates to: There exists an integer x such that x is greater than 5 and the square of x is smaller than 40.

Using expected value, it is found that the minimum jackpot would need to be of $584,402,676.

-------------------------

Thus, the number of total outcomes is:

\(T = 26C_{69,5} = 26 \times \frac{69!}{5!64!} = 292201338 \)

The minimum expected value that makes the game fair is 0, thus:

\(\frac{1}{292201338}x - \frac{292201337}{292201338}(2) = 0\)

\(x - 2(292201337) = 0\)

\(x = 584402676 \)

The minimum jackpot would need to be of $584,402,676.

Based on this evidence and reasoning, it is reasonable to conclude that Brianna should get the credit card, as long as she uses it responsibly and pays off her balance in full every month to avoid paying interest charges.

Percent, denoted by the symbol "%", is a way of expressing a fraction or ratio as a portion of 100. It is commonly used in everyday life to express a part of a whole or to compare quantities. Percentages can be used in various contexts, such as in finance to calculate interest rates, in statistics to represent data, and in everyday life to express discounts, tax rates, and tips. It is important to understand percentages to make informed decisions and to effectively communicate information.

Here,

CER stands for Claim, Evidence, and Reasoning, which is a framework for presenting a persuasive argument. Using this framework, we can evaluate whether Brianna should get the credit card in question:

Claim: Brianna should get the credit card.

Evidence:

The credit card has an APR of 24.99%, which is high compared to other credit cards.

The credit card has a yearly fee of $150.00.

The credit card offers 1% cash back on most purchases.

Reasoning:

While the APR and yearly fee are high, Brianna can still benefit from using the credit card to build her credit.

The 1% cash back on most purchases can help offset the cost of the yearly fee and the interest charges if she pays off her balance in full every month.

By using the credit card, such as making payments on time and not carrying a high balance, Brianna can establish a positive credit history, which can help her in the future when she wants to apply for loans or other credit cards.

Certainly! The problem can be solved using the Pythagorean theorem,

which states that in a right triangle, the square of the hypotenuse is equal to the sum of the squares of the other two sides.

In this case, the ladder acts as the hypotenuse, and we need to find the length of the vertical side (height) it reaches up the wall.

The ladder forms the hypotenuse, and its length is given as 12 meters. The distance from the foot of the ladder to the base of the wall represents one side of the triangle, which is 4.5 meters.

By substituting the given values into the Pythagorean theorem equation: (12m)^2 = h^2 + (4.5m)^2, we can solve for the unknown height 'h'.

Squaring 12m gives us 144m^2, and squaring 4.5m yields 20.25m^2. By subtracting 20.25m^2 from both sides of the equation, we isolate 'h^2'.

We then take the square root of both sides to find 'h'. The square root of 123.75m^2 is approximately 11.12m.

Therefore, the ladder reaches a height of approximately 11.12 meters up the wall.

The statement "Δ ABD = Δ ACB by SSS" is true about the diagram.

The statement "Δ ABD = Δ ACB by SSS" is true about the diagram. SSS stands for Side-Side-Side, which is a congruence postulate stating that if three sides of one triangle are congruent to the corresponding sides of another triangle, then the triangles are congruent. In the given diagram, Δ ABD and Δ ACB are congruent because their corresponding sides AB, BD, and AC are equal in length.

This means that the triangles have the same shape and size, but they may be oriented differently. The SSS congruence allows us to conclude that all corresponding angles and other corresponding sides of the two triangles are also congruent. Therefore, we can say that Δ ABD is congruent to Δ ACB based on the Side-Side-Side congruence.
