Answer 1

Answer:

30 Degrees

Step-by-step explanation:

all triangles are 180 degrees, therefore 180-130-20=30

Answer 2

It’s 30 degrees, because 130+20= 150 degrees and 180-150= 30 degrees.

FIND THE SURFACE AREA. I WILL MARK YOU A BRAINLEST IF THE ANSWER IS RIGHT

Answers

Answer:

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

I need help with question 18. The answer is53√3 ft^2. But how do I get there?

Answers

Answer:

Hope it helps....

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

= 52√3

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.

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

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

⦁ Convert the vertex form of the equation you wrote above to standard form.

Answers

Answer:

ax^2 + bx + c

Step-by-step explanation:

im pretty sure this answers your question

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

Answers

Answer:

I'll do the dilation for the first point and you will see the answer (please verify the second point)

Step-by-step explanation:

The dilation about the origin is straightforward, you just multiply the coordinates of each point by the scale factor.

so the dilated point for (-4,-4) is -4x3.5= -14 which is the same for the y coordinate.

so the dilated point for (-4,-4) is (-14, -14)

Please verify by computing the dilated point for (-6,4)

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

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
