Answers:

B = 50

a = 10.9

c = 17.0

================================================

Explanation:

This is a right triangle, so the acute angles are complementary, meaning they add to 90

B+40 = 90

B+40-40 = 90-40

B = 50

Also, because this is a right triangle, we can use trig ratios to compute the missing sides

tan(angle) = opposite/adjacent

tan(40) = a/13

a = 13*tan(40)

a = 10.908

a = 10.9

cos(angle) = adjacent/hypotenuse

cos(40) = 13/c

c*cos(40) = 13

c = 13/cos(40)

c = 17.0

Answer:

The correct option is D.

Step-by-step explanation:

From the given figure it is noticed that the vertices of the parallelogram are F(-6,-1), G(-1,-1), H(-2,-4) and I(-7,-4).

In order to build a scale model of the trail, the drawing is enlarged on the coordinate plane.

Distance formula

[tex]d=\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}[/tex]

[tex]FI=\sqrt{(-7-(-6))^2+(-4-(-1))^2}=\sqrt{1+9}=\sqrt{10}[/tex]

[tex]AD=\sqrt{(1-3)^2+(2-8)^2}=\sqrt{4+36}=2\sqrt{10}[/tex]

The scale factor is

[tex]\frac{AD}{FI}=\frac{2\sqrt{10}}{\sqrt{10}}=2[/tex]

Therefore the length of sides of image is twice of preimage.

The vertices A and D are image of F and I respectively.

The length of FG is

[tex]FG=\sqrt{(-1-(-6))^2+(-1-(-1))^2}=\sqrt{25}=5[/tex]

Therefore the length of AB is 10 units and length of CD is also 10 units.

The point which is on horizontal distance of 10 units from A(3,8), is B(13,8).

The point which is on horizontal distance of 10 units from D(1,2), is C(11,2).

Therefore vertices B and C are image of G and H respectively. The another corner points are (13,8) and (11,2). Option D is correct.

Answer: D) (13, 8)

Answer:

Perimeter≈113.57 and Area= A≈498.84

Step-by-step explanation:

Ok so the Perimeter is approximately 113.57. the formula of a perimeter of a right triangle is P=a+b+√a²+b²

so since a and b are the leg in the right riangle then the value we are gonna be working with are 24 and 41.57

so basically the equation states this: P=24+41.57+√24²+41.57²

so 24+41.57 is 65.57

24²=576 and 41.57²=1728.1(rounded) add that and you get 2304.1. the square root of 2304.1 is 48.00104166 or just 48. add that to 65.57 and you get 113.57

Now for area.

the area of right triangle is ab/2

so 24times 41.57 divided by 2

24 times 41.57= 997.68

divide that by 2 and you get 498.84

The perimeter of the triangle is 113.57 feet and its area is 498.84 square feet.

The perimeter of a triangle is the sum of its sides: 24 feet + 41.57 feet + 48 feet = 113.57 feet. The area of a right triangle is calculated by using the formula 1/2*base*height. In this case the base is 24 feet and the height is 41.57 feet, so the area would be 1/2*24*41.57 = 498.84 square feet.

Answer:

y =-1

Step-by-step explanation:

We are given a point (-2,-1)

Also given that a horizontal line passes through the above point.

We have to find the equation of the horizontal line.

We know that any straight line in xy plane is of the form

y = mx+b where m=slope of line and b = y intercept.

Here given that the line is horizontal and hence the angle it makes with x axis is 0.

Slope of line= m = tan 0 =0

Hence equation of line using point slope form is

y-y1 = m(x-x1) .  Here m =0 and (x1,y1) = (-2,-1)

Hence equaiton of line is

y+1 =0(x+2)

Or y =-1

So option A is right answer.

Answer:

Perimeter = 64.75 ft

Area = 213.91 ft

Step-by-step explanation:

13.875 ÷ 3 = 4.625

4.625 x 5 = 23.125 ft (This is the length of the rectangle)

4.625 x 2 = 9.25 ft (This is the width of the rectangle)

(23.125 x 2) + (9.25 x 2) = 64.75 ft (Perimeter)

23.125 x 9.25 = 213.90625 ft, or 213.91 ft if rounded to 2 d.p (Area)

The perimeter of the rectangle is approximately 64.75 feet and the area is approximately 213.91 square feet.

[tex]\[L = W + 13.875\][/tex]

We can use these two equations to solve for the values of \(L\) and \(W\).

First, let's use the ratio to set up an equation:

[tex]\[\frac{L}{W} = \frac{5}{2} \implies L = \frac{5}{2}W\][/tex]

Next, substitute this expression for L into the second equation:

[tex]\[\frac{5}{2}W = W + 13.875\][/tex]

Solving for w

[tex]\[\frac{3}{2}W = 13.875\][/tex]

[tex]\[W = \frac{2}{3} \times 13.875\][/tex]

[tex]\[W = 9.25\][/tex]

Now, use this value of \(W\) to find the length \(L\):

[tex]\[L = \frac{5}{2} \times 9.25 = 23.125\][/tex]

Now that we have the dimensions, we can calculate the perimeter and area:

1. perimeter of a rectangle with length \(L\) and width \(W\) is given by:

[tex]\[P = 2(L + W)\][/tex]

Substituting the values:

[tex]\[P = 2(23.125 + 9.25) \approx 64.75 \text{ feet}\][/tex]

2. Area of a rectangle is given by:

[tex]\[A = L \times W\][/tex]

Substituting the values:

[tex]\[A = 23.125 \times 9.25 \approx 213.91 \text{ square feet}\][/tex]

So, the perimeter of the rectangle is approximately 64.75 feet and the area is approximately 213.91 square feet.

Answer:

5/8

Step-by-step explanation:

First we need to figure out how many girls  and boys there are.

g = girls

b = boys

g = b+8  ( eight more girls than boys)

b = g-8

There are 32 students)

g+b =32

Substitute b = g-8 into the equation

g + (g-8) = 32

Combine like terms.

2g-8 = 32

Add 8 to each side.

2g -8+8 = 32+ 8

2g = 40

Divide by 2

g = 20

There are 20 girls

The experimental probability of picking a girl is

girls/ total

20/32 = 5/8  

3x + 7y = 48

5x - 7y =-32

8x = 16

 x = 2

3(2) +7y = 48

7y = 42

y = 6

By analyzing the equation and using provided options, we find that the right values for the digits x, y, and z are 1, 2, and 3 respectively. When multiplied together, the product (x)(y)(z) equals 6.

The mathematical problem you've presented is akin to a simple addition of numbers, but with a twist: the digits x, y, and z each represent different unknown digits. Our task is to determine the value of the product (x)(y)(z) given the vertical addition:

Looking at the addition, we can see that when we add the second digit of the second row (2) with the first digit of the third row (x), the result must be a digit with a 1 carried over because there is a 1 in the hundred's place of the result. That means 2 + x has to be equal to 10 or 11 (since x is a digit, the highest value for x could be 9).

Using the option provided (d) x. 1, y. 2, z. 3, we can see that the column with z's would sum to 7 (4z), the column with x's would sum to 11 (since 1 + x = 11, x = 1), and the column with y's would sum to 14 (since y would then be 2) which fits the pattern of the problem provided. Therefore, the values for x, y, and z are 1, 2, and 3 respectively.

The value of (x)(y)(z) is thus 1 × 2 × 3 = 6.

Final answer:

To find the value of (x)(y)(z), we need to solve the equation 4z/27 + x5/y14 = 0. By substituting different values for x, y, and z, we find that (x)(y)(z) = 6.

Explanation:

To find the value of (x)(y)(z), we need to solve the given equation:

4z/27 + x5/y14 = 0

Since x, y, and z each represent a different digit from 0 to 9, we can try different values to solve for (x)(y)(z).

Let's start with the first term: 4z/27. The only possible value for z is 2, because 4z/27 must give us a rational number. So, let's substitute z = 2 into the equation:

4(2)/27 + x5/y14 = 0

8/27 + x5/y14 = 0

Next, let's solve for the second term: x5/y14. To make this term equal to 0, we can set x = 1 and y = 3. Substituting these values into the equation:

8/27 + 15/314 = 0

Now, let's find the value of (x)(y)(z) = (1)(3)(2) = 6.

Sample space--

A sample space is a set which contains the set of all the possible outcomes or results that could occur while performing an experiment.

i.e. the sample space while flipping a coin is: {H,T}

The sample space while tossing a six-sided die is: {1,2,3,4,5,6}

Here it is given that:

A bag has six balls labeled:  A,B,C,D,E,F

        This means that the sample space is given by:

                      Sample space={ A,B,C,D,E,F}

             Then the sample space is:

                      Sample space= {D,E,F}

The sample space of a bag with balls labeled A to F is {A, B, C, D, E, F}. For the event of choosing a letter from A to E, the outcomes are {A, B, C, D, E}.

To answer the student's question about the sample space and the event of choosing a letter from A to E, we must first understand the concept of sample space in probability. The sample space is the set of all possible outcomes of a probability experiment. In this case, since the bag contains six balls labeled A, B, C, D, E, and F, the sample space describing all possible outcomes is {A, B, C, D, E, F}.

Now, the event of choosing a letter from A to E simply means finding all the outcomes within the sample space that meet the criteria of being letter A, B, C, D, or E. Therefore, the outcomes for this event are {A, B, C, D, E}.
