Find the area of the triangle with A = 60°, b = 11 feet, and c = 8 feet. Round to the nearest tenth.

Answers

Answer:

41.25 ft^2

Step-by-step explanation:

Literally all you need to do is Pythagorean Theroem.

a = ?

b = 11ft

c = 8ft

a^2 + b^2 = c^2

a^2 + 11^2 = 8^2

a^2 + 121 = 64

64 - 121 = a^2

a = 7.5

Then area of a triangle formula is (bh)/2

(11 x 7.5)/2 = 41.25

In triangle QRS the measurement of an angle RSQ is 29.1 and the measure of angle QRS is 70 degrees what is the measurement of sqr

Answers

Answer: The measure of ∠SQR= 80.9°

Step-by-step explanation:

Given: In triangle QRS,

∠ RSQ = 29.1° and ∠QRS=70°

To find: ∠SQR

Angles sum property of triangle = Sum of all the angles in a triangle is 180°.

For Δ QRS,

∠SQR + ∠ RSQ +∠QRS = 180°

⇒ ∠SQR + 29.1° + 70° = 180°

⇒ ∠SQR + 99.1° = 180°

⇒ ∠SQR= 180°-99.1

⇒ ∠SQR= 80.9°

Hence, the measure of ∠SQR= 80.9°

Aliza needs to run at a rate faster than 8.8 feet per second in order to exceed her fastest time in a race. After running for 15 minutes, her coach determines that she is running at an average rate of 5.8 miles per hour. He converts the average rate to feet per second as shown below: He concludes that she is not running fast enough to exceed her fastest time. What errors did the coach make? Check all that apply. He used an incorrect time ratio converting hours to minutes. His units do not cancel. He used an incorrect distance ratio converting miles to feet. He incorrectly concluded that she is not running fast enough. He cannot determine her average rate in miles per hour after only 15 minutes.

Answers

Answer:

a.  He used an incorrect time ratio converting hours to minutes.

d. He incorrectly concluded that she is not running fast enough.

Step-by-step explanation:

Looking at the Coach's method of conversion when converting time, he assumed that an hour had 15 minutes instead of 60 minutes. He therefore did not use the correct time ratio to convert hours to minutes.

The coach's calculations yielded an answer of 34 ft/s. This is way faster than 8.8 ft/ s so his deduction that she was not running fast enough to beat her fastest time is incorrect because at that inhumane speed, she did.

Answer: A.)He used an incorrect time ratio converting hours to minutes.

D.)He incorrectly concluded that she is not running fast enough.

Graph the image of the figure after a dilation with a scale factor of 3 centered at (2, −7).

Use the Polygon tool to graph the quadrilateral by connecting all its vertices.

Answers

Answer:

Step-by-step explanation:

Each point moves 3 times the distance from the center of dilation that it was.

You can compute the new coordinates by ...

 L = P - O . . . . . the length from O to P is P-O for some point P and origin O

Then 3 times that distance is

 3L = 3P -3O

We want to find the point P' that is 3L from O, so we add this distance to the coordinates of O. We get ...

 P' = 3L +O = 3P -3O +O

 P' = 3P -2O

So, for the lower left point A(-2, -7), the dilated image point A' is ...

 A' = 3(-2, -7) -2(2, -7) = (-6, -21) +(-4, 14) = (-10, -7)

That is, ...

 A' = 3A +(-4, 14)

The coordinates of the remaining points can be found similarly.

___

On a graph, it is usually fairly easy to count the grid squares in each direction between the point of interest and the center of dilation. The image point is 3 times the distance in each direction (horizontally, vertically).

Jill orders t-shirts on Amazon. Each shirt costs $15.00 including tax. A one-time shipping fee of $3.25 is added to the cost of the order. The total cost of Jill's order is $78.25. How many t-shirts did Jill order? *

Answers

Answer:

5 shirts

Step-by-step explanation:

Step one:

given data

Each shirt costs $15.00 including tax.

A one-time shipping fee of $3.25

The total cost of Jill's order is $78.25

Step two:

let the number of shirts be x

so

y=15x+3.25

for y= $78.25, let us find x

78.25=15x+3..25

collect like terms

75= 15x

divide both sides by 15

x=75/15

Step-by-step explanation:

The perimeter of the rectangle is (20x + 6)inches

The perimeter of a rectangle

The formula for calculating the perimeter of a rectangle is expressed as:

P = 2l + 2w

Given that;

l = 8x - 1

w = 2x + 4

Susbtitute

P = 2(8x - 1) + 2(2x + 4)

Expand

P = 2(8x) - 2(1) + 2(2x) + 2(4)

P = 16x - 2 + 4x + 8

P = 16x + 4x - 2 + 8

P = 20x + 6

Answer:

We conclude that:

m∠XWY = 41°

Step-by-step explanation:

Given

m∠VWX = 139°

m∠YWZ = 23°

To determine

m∠XWY = ?

We know the measure of the angle of a straight is 180°.

As m∠VWX and m∠XWY lie on a straight line.

Thus, the sum of m∠VWX and m∠XWY must be 180°

so we get the equation

m∠VWX + m∠XWY =  180°

Given that m∠VWX = 139°

so substituting m∠VWX = 139° in the equation m∠VWX + m∠XWY =  180°

139° + m∠XWY = 180°

m∠XWY = 180° - 139°

m∠XWY = 41°

Therefore, we conclude that:

m∠XWY = 41°
