The area of a right triangle can be found by multiplying half of the length of the base by the height.

The formula for the area of a right triangle is:

Area = (1/2) * base * height

It is important to note that the base and height must be perpendicular to each other, forming a right angle in the triangle. If the triangle is not a right triangle, then the area cannot be found using this formula.

To use this formula, simply measure the length of the base and height and plug these values into the formula. The result will be the area of the triangle, expressed in square units.

It is also worth noting that the height and base of a right triangle can be any two sides that form a right angle, not just the sides that are labeled as the base and height.

Answer:

Area = 200ft²

Step-by-step explanation:

Perimeter of a rectangle = 2(length+width)

Area of a rectangle = length * width

Then:

g = 2w           Eq. 1

60 = 2(g+w)   Eq. 2

g = length

w = width

From Eq. 2

60 = 2g + 2w

60 - 2g = 2w      Eq. 3

matching Eq. 1 and Eq. 3

g = 60 - 2g

g + 2g = 60

3g = 60

g = 60/3

g = 20 ft

From Eq. 1

g = 2w

20 = 2w

20/2 = w

w = 10 ft

Area

area = length * width

area = 20ft * 10 ft

area = 200ft²

The value for A∪B in probability form is 3/4. The value for A∪B in data set form is {5, 6, 8}.

What is probability?

Probability is a way to gauge how likely something is to happen. Many things are difficult to forecast with absolute confidence. Using it, we can only make predictions about the likelihood of an event happening, or how likely it is. Probability can range from 0 to 1, with 0 denoting an impossibility and 1 denoting a certainty.

The event U has data - U = {1, 2, 3, 4, 5, 6, 7, 8}

The event A has data - A = {6, 8, 10}

The event B has data - B = {5, 6, 9, 12}

The event C has data - C = {1, 3, 7}

The probability formula is -

Probability = No. of outcomes that is favorable / Total number of outcomes

The value for A∪B is -

A∪B = 3/4

The value of A∪B in data set is the values that are present in U data set and in A and B data set.

Answer: The probability that no man will be selected is the number of ways that only women can be selected divided by the total number of combinations of candidates for the 2 data analyst positions. There are 2 ways to choose 2 women from the 2 available women, and there are C(4,2) = 6 ways to choose 2 candidates from the 3 men and 2 women, so the probability that no man will be selected is 2/6 = 1/3.

The probability that both men will get selected is the number of ways to choose 2 men from the 3 available men divided by the total number of combinations of candidates for the 2 data analyst positions. There are C(3,2) = 3 ways to choose 2 men from the 3 available men, and there are C(5,2) = 10 ways to choose 2 candidates from the 3 men and 2 women, so the probability that both men will get selected is 3/10 = 3/5.

Answer:

The flagpole is 15 ft tall.

Step-by-step explanation:

In this problem, we are asked to create a proportion of similar triangles to solve for the height of a flagpole.

We are given an equation with the proportion:

[tex]\dfrac{h}{6\text{ft}}=\dfrac{\square}{\square}[/tex]

We can fill in the blanks as follows:

[tex]\dfrac{h}{6\text{ft}}=\dfrac{25 \text{ft}}{10 \text{ft}}[/tex]

Notice that the heights of the triangles compared are both in the numerator, and the lengths of both triangles are in the denominator.

Then, to solve for the height of the flagpole, we can isolate the variable h in the proportion.

[tex]\dfrac{h}{6}=\dfrac{25}{10}[/tex]

↓ multiply both sides by 6

[tex]h = \dfrac{150}{10}[/tex]

↓ simplify the fraction

[tex]h = 15 \text{ ft}[/tex]

So, the flagpole is 15 ft tall.

Step-by-step explanation:

The hare can afford to nap for a maximum time of 3,690 seconds without losing the race if his speed is 15 m/s.

After running for 7 seconds, the hare has covered a distance of:

[tex]distance = speed \times time\\distance = 15 \times 7\\[/tex]

distance = 105m

The hare is now 895 m away from the starting line and 100 m away from the finish line.

The hare needs to cover a distance of 100 m to reach the finish line, while the tortoise needs to cover a distance of 895 m.

calculate the time it would take the tortoise to reach the finish line:

[tex]time = \frac{100}{0.27}[/tex] = 3704 seconds

The maximum speed of the hare is 15 m/s, which means the time it would take the hare to cover the distance is:

[tex]time = \frac{100}{15}[/tex] = 6.67 seconds

so, the time hare have to nap so that he does not lose race = 3704 - (7+6.67) ≅3690 seconds

The measures of angles C and D are 70° and 100°, respectively.

Understanding angles is a fundamental concept in geometry. A quadrilateral is a polygon with four sides, and its angles are essential to determining its properties.

Let's start by labeling the angles in the quadrilateral. We know that two angles measure 100° and 90°, so let's label them as A and B, respectively. The other two angles, which we are trying to find, can be labeled as C and D.

Now, we are given that the ratio of angles C and D is 7:10. This means that we can write the following equation:

C/D = 7/10

We can use this equation to solve for one of the angles. Let's choose angle C. We can rewrite the equation as:

C = (7/10)D

We also know that the sum of the angles in a quadrilateral is 360°. Therefore, we can write another equation:

A + B + C + D = 360°

We can substitute the values we know into this equation and solve for angle D:

100° + 90° + (7/10)D + D = 360°

Simplifying the equation:

(17/10)D = 170°

D = 100°

Now that we know the value of angle D, we can use the equation we derived earlier to find the value of angle C:

C = (7/10)D = (7/10) x 100° = 70°

Figures are nothing but a kind of drawing which we make using lines and arcs. Figures can be 2-D or 3-D. In mathematics these figures are studied by calculating their's area, perimeter, surface area, volume, etc.

In mathematics when we draw a figure using line and arcs and the resultant figure has some specific pre-defined properties then such figures are called shapes.

The coordinates of the given figure ABCD are

A=(-2,2); B=(1,1); C=(1,-1) and D=(-1,0)

As we have to dilate the figure by the factor of 3 from the origin which means we have to enlarge the figure 3 times with same origin, then we simply multiply the coordinates of the given figure by 3.

Dilated coordinates will be

A=(-2×3,2×3)=(-6,6)

B=(1×3,1×3)=(3,3)

C=(1×3,-1×3)=(3,-3)
