Answer:

c=21.6

Step-by-step explanation:

First, find the last angle of the triangle.

The sum of all the angles in a triangle is 180 degrees.

A+90+37=180

A=53

Now find x

The cosine of an angle is equal to the ratio of the adjacent side to the hypotenuse.

cos(B)=adj/hyp

rewrite as

c=a/cos(B)

c=17.3/cos(37)

c=21.66194688

Answer:

B. He used the wrong expression to represent the area of the base of the pyramid.

Step-by-step explanation:

Given

See attachment for pyramid

[tex]Area = (33.2)(34.2) + 4 * \frac{1}{2} * 34.4 * 28.4[/tex]

Required

Vikram's error

The surface area of a square pyramid is:

[tex]Area = Base\ Area + 4 * Area \triangle[/tex]

Where

[tex]Base\ Area = Length * Length[/tex]

[tex]Base\ Area = 34.2 * 34.2[/tex]

[tex]4 * Area \triangle = 4 * \frac{1}{2} * Base * Height[/tex]

[tex]4 * Area \triangle = 4 * \frac{1}{2} * 34.2 * 28.4[/tex]

So:

[tex]Area = Base\ Area + 4 * Area \triangle[/tex]

[tex]Area = 34.2 * 34.2 + 4 * \frac{1}{2} * 34.2 * 28.4[/tex]

By comparing the calculated expression with

[tex]Area = (33.2)(34.2) + 4 * \frac{1}{2} * 34.4 * 28.4[/tex]

Option (b) is correct

Answer:

measure of angle F=    109 degrees

Step-by-step explanation:

I believe by m you are solving for angle F.  So, angle H =71 degrees. GF and HI are parallel. In order to find angle G, Take the supplementary of 71 degrees, so 180-71 = angle G =109 degrees. Because GH and FI are congruent, the angles should be same across the shape, so angle I 71 degrees. Quadrilateral has a total of 360 degrees, so, 360-71-109-71=109 degrees. In general, angke G would equal angle F because of the trapezoid properties that take place when both bases are parallel and two of the sides are congruent, the trapezoid is an isosceles trapezoid

Answer:

The coordinate of the rest stop is: [tex](5,2.5)[/tex]

The distance between the hotel and the stadium is 32 miles

Step-by-step explanation:

Given

[tex](x_1,y_1) = (3,4)[/tex] --- Team hotel

[tex](x_2,y_2) = (7,1)[/tex] --- Stadium

Solving (a): The coordinates of the rest stop

The rest stop is at half way;

So, the coordinate is:

[tex](x,y) = \frac{1}{2}(x_1+x_2,y_1+y_2)[/tex]

This gives:

[tex](x,y) = \frac{1}{2}(3+7,4+1)[/tex]

[tex](x,y) = \frac{1}{2}(10,5)[/tex]

Open bracket

[tex](x,y) = (5,2.5)[/tex]

Solving (b): Distance between the hotel and the stadium

We have:

[tex](x_1,y_1) = (3,4)[/tex] --- Team hotel

[tex](x_2,y_2) = (7,1)[/tex] --- Stadium

The distance (d) is:

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

So, we have:

[tex]d = \sqrt{(3 - 7)^2 + (4 - 1)^2}[/tex]

[tex]d = \sqrt{(-4)^2 + 3^2}[/tex]

[tex]d = \sqrt{16 + 9}[/tex]

[tex]d = \sqrt{25}[/tex]

[tex]d =5[/tex]

From the question, we have:

[tex]1\ unit = 6.4\ miles[/tex]

So:

[tex]d =5 * 6.4\ miles[/tex]

[tex]d =32\ miles[/tex]

Answer:

c=1

Step-by-step explanation:

9c+1 = 10

Subtract 1 from each side

9c+1-1=10-1

9c = 9

Divide by 9

9c/9 = 9/9

c = 1

Answer: 24 2/3

Step-by-step explanation:

Let the total distance of the race be represented by x.

Therefore, based on the information given, we can form an equation which will be:

3/8 of x = 9 1/4

3/8x = 9 1/4

0.375x = 9.25

x = 9.25/0.375

x = 24.67

The distance of the race is 24 2/3

Answer:

3a(c + 2b - 5)

Step-by-step explanation:

Step-by-step explanation: The greatest common factor for the 3 terms here is 3a so factor out a 3a and what we're left with inside the parentheses is each of the terms in the original polynomial divided by 3a.

So we have 3a(c + 2b - 5) which is our final answer.

Answer:

11.5 years

Step-by-step explanation:

Given data

Principal= $400

Rate= 6%

For the compound interest at time t, the expression is given as

A= P(1+r)^t

Substitute

A= 400(1+0.06)^t

A=400(1.06)^t

B. How much money is in Jennifer's account after 5 years

put t= 5

A=400(1.06)^5

A=400*1.338

A=$535.2

C. Approximately when will Jennifer have $800 in her account

A=$800

P=$400

r=6%

t= ln(A/P)/r

t= ln(800/400)/0.06

t= ln(2)/0.06

t= 0.6931/0.06

t=11.551

Hence the time is about 11.5 years

Answer:

Step-by-step explanation:

Perimeter is found by adding all the sides of a figure together. We have 2 lengths that are 10.5 long, and 2 widths that are 8.75 wide. Adding these together:

10.5 + 10.5 + 8.75 + 8.75 = 38.5 cm

this answer for # 2 question

Answer:

21 feet

Step-by-step explanation:

Remember to get feet to yards, multiply the feet by 3 because there are 3 feet in one yard

in this case 7 × 3 = 21

And additionally to get yards to feet, divide by three because 1 yard = 3 feet

f(x) = square root of (-7 + 2) - 6

f(x) =square root of (-5) - 6

f(x) = 2.236 = 2.2 - 6

f(x) = -3.8

F(x) = √x+2 -6

F(x) = √7+2 -6

F(x) = 3-6

F(x) = -3

Answer: $9,500

Step-by-step explanation:

If the value of the car depreciates by 5% in a year it means that the value of the car reduced by 5%.

First find the 5%:

= 5% * 10,000

= $500

Subtract this from the initial value to find the value after a year:

= 10,000 - 500

= $9,500

Answer:

$ 9500

Step-by-step explanation:

From the question given above, the following data were obtained:

Initial value = $ 10000

Depreciation rate = 5%

Value after one year =?

Next, we shall determine the depreciation value. This can be obtained as follow:

Initial value = $ 10000

Depreciation rate = 5%

Depreciation value =?

Depreciation value = Initial value × rate

Depreciation value = 10000 × 5%

Depreciation value = 10000 × 5/100

Depreciation value = $ 500

Finally, we shall determine the value of the car after one year. This can be obtained as follow:

Initial value = $ 10000

Depreciation value = $ 500

Value after one year =?

Value after one year = Initial value – Depreciation value

Value after one year = 10000 – 500

Value after one year = $ 9500

Therefore, the value of the car after one year is $ 9500
