One interior angle of a triangle is 60'. The other angle measures are x' and y'. Which of the following could be the values of x
and y? Select all that apply.
A x = 50, y = 90
B. * = 100, y = 20
C. x = 45, y = 45
D. X = 40, y = 80
E. x = 60, y = 60

Answers

Answer:

B. x = 100, y = 20

D. X = 40, y = 80

E. x = 60, y = 60

Step-by-step explanation:

The sum of interior angles of a triangle = 180°

From the above question, one of the angles = 60°

The value for the two other interior angles = 180° - 60° = 120°

Hence, the following options could be the values of x and y is given as x + y = 120

Therefore,

B. x = 100, y = 20

D. X = 40, y = 80

E. x = 60, y = 60

Answers

Answer:

A. (-4, -4)

Step-by-step explanation:

According to the word problem, a dilation of (0.75x, 0.75y) is applied to a triangle.

This means the original coordinates were enlarged/multiplied by 0.75.

We can multiply the coordinates at the bottom by 0.75 to see if we get any of the resulting images' coordinates.

We could divide the resulting images' coordinates by 0.75 to see if we get any of the answers on the bottom.

For instance,

(-3, -3)

-3 / 0.75 = -4 (x-coordinate)

-3 / 0.75 = -4 (y-coordinate)

This means (-4, -4) were the original coordinates of (-3, -3) before the dilation of 0.75.

Step-by-step explanation:

Given :

Using cosine rule :

c² = a² + b² - 2abCosC

c² = 45² + 25² - 2(45)(25) - cos70

c² = 2650 - 2250 * - 0.3420201

c² = 2650 + 769.54532

c² = 3419.5453

c = sqrt(3419.5453)

c = 58.476

A cell phone company expects that every 2 out of 25 cell phones will have some formof defect. At this rate, how many cell phones out of 500 will be expected to have a defect?

Answers

Answer: 40 phones

Step-by-step explanation:

The company expects that every 2 out of 25 phones will have some form of defect.

In percentage terms, this is:

= 2 / 25 * 100%

= 8%

If there are 500 phones therefore, the defected phones would still be the same percentage and the actual number would be:

= 8 % * 500

= 40 phones

find the compound interest on $500 for 8 years. if the interest rate is 3%

Write an equation of the line, in point-slope form, that passes through the points (–7, 2) and (3, –2). Use (–7, 2) as the point (x1, y1)

Answers

Answer:

first use the equation m = y2 - y1 / x2- x1 to get the slope

m = -2 - 2 = -4

m = 3 + 7 = 10 when there is a negative for x1 it turns positive

the slope is -4/10 or -2/5

now plus the info into the point slope equation

y - y1 = m (x-x1)

this is in point slope form y - 2 = -2/5 (x + 7)

This is how to get it in y-intercept form

y -2 = -2/5x + -2.8

now add -2 on both sides to the -2.8

y = -2/5x (Slope) + -0.8 y- intercept

Step-by-step explanation:

Answer:

52√3 ft²

Step-by-step explanation:

sin 60° = (√3) / 2 = h/8

h = 8 x (√3) / 2 = 4√3

cos 60° = 1/2 = a/8

a = 4 b = 15-4 = 11

area = left triangle + right rectangle

area = (4*4√3) / 2 + 11*4√3

= 8√3 + 44√3

The standard form of the vertex form equation is y = 2x² - 12x + 17

How to convert the equation?

The vertex form of a quadratic equation is represented as:

y = a(x - h)² + k

Using the above form, the quadratic equation can be represented as:

y = 2(x - 3)² + 1

Expand

y = 2(x² - 6x + 9) - 1

Further expand

y = 2x² - 12x + 18 - 1

Evaluate the like terms

y = 2x² - 12x + 17

Hence, the standard form of the vertex form equation is y = 2x² - 12x + 17

SA= 222cm ^2

Step-by-step explanation:

Surface area of the prism = (Perimeter of the base of the prism) × height + 2(area of the base)

Perimeter of the base = 5 + 3 + 2 + 2 + 2 + 3 + 5 + 8

= 30

Area of the base = 8×5 - 2×2 = 36 cm²

Surface area of the prism = 30×5 + 2×(36)= 222 cm²

Ok my question says "destiny and carla had a total of 3 gallons of paint to share for a project they had 1 gallon each yellow blue and red paint destiny used 3/8 gallon of yellow paint 1/2 of blue paint 1/4 of red paint carla used 1/4 of yellow 3/8 of blue and 1/4 of red then part a ask how much more paint in gallons did destiny use than carly

Answers

Answer: 1/4

Step-by-step explanation:

Since Destiny used 3/8 gallon of yellow paint, 1/2 of blue paint and 1/4 of red paint, the total paint used will be:

= ⅜ + ½ + ¼

= 3/8 + 4/8 + 2/8

= 9/8

= 1 1/8

Carla used 1/4 of yellow, 3/8 of blue and 1/4 of red. The total paint used will be:

= 1/4 + 3/8 + 1/4

= 2/8 + 3/8 + 2/8

= 7/8

The numybe of paint that Destiny use more than Carla will be:

= 1 1/8 - 7/8

= 2/8

= 1/4

Destiny used 1/4 paint more than Carla

If CosA= sqrt 3/2, what is TanA?

Answers

Answer:

√(3)/3

Step-by-step explanation:

cos(A) = adj./hyp.

adj. = √(3) or √(3)/2

hyp. = 2 or 1

use unit circle:

hyp. = 1

adj. = √(3)/2

use pythagorean theorem c² - b² = a²

1² - (√(3)/2)² = 1 - 0.75 = 0.25

a² = 0.25

a = √(0.25)

a = 0.5

tan(A) = opp./adj.

tan(A) = 0.5/(√(3)/2)

tan(A) = 1/√(3)

rationalize

tan(A) = √(3)/3

The foreign secretary wanted to be certain that this message reached von Bernstorff, so he made arrangements for it to be carried aboard a U-boat to Sweden and from there to Washington through diplomatic channels.As luck would have it, the departure of the sub was delayed. Impatient, Zimmermann turned to his second option: sending the message to his ambassador through the U.S. State Department. Although Wilson considered the United States to be neutral, he allowed messages to be sent to von Bernstorff via the State Department as a courtesy. The telegram sent, Zimmermann waited for a reply. What Zimmermann didn't know was that the British were doing a thorough job of intercepting German wireless transmissions.Why did Zimmermann choose to send the message through the U.S. State Department?The German U-boat was grounded because it needed repairs.The Americans planned to enter the war and side with the Germans.The content of the message was extraordinarily important.The safest way of transmitting messages was by telegram. in a random School sampling of 50 middle school students it was found that 18 students bring their lunch to school everyday if there are 942 students in the school predict how many bring their lunch to school each day The parabola is swached vertically by a factor of 5.
