Who can answer this ASAP

Answer:

1. If x and y are supplementary angles, then y is sometimes acute because supplementary angles are angles that add up to 180 degrees. So, y can be acute while x can be obtuse, y can be obtuse while x can be acute, or both can be right angles.

2. If x and y are complementary angles, then x is never obtuse. Complementary angles are angles that add up to 90 degrees, and obtuse angles are angles over 90 degrees, so it's impossible to have an obtuse angle as a complementary angle.  

Step-by-step explanation:

Answer:

1) Sometimes

2) Never

Step-by-step explanation:

1) you could have two angles add up to 180 degrees and one of them could be less than 90

example, x = 140° and y = 40°

2) if two angles are complementary then their sum is 90° so neither angle must be less than 90°, thereby making them both acute angles

Answer:

25.7m

Step-by-step explanation:

Pythagorean Theorem: a^2+b^2=c^2

28^2+b^2=38^2

784+b^2=1444

b^2=660

b=25.6904652 or 25.7m

Answer:

17) see explanation

18) 3850 ft^2

Step-by-step explanation:

17) not sure where area  is being shaded. so i can't help you with that one. if you could clarify i could edit this or send a separate answer for it

18) find the area of the two rooms. both have a 50x40 room so the total area is 4000 ft^2. But, there is an overlap so you need to subtract the aquarium once. the area of the aquarium is 30*5 = 150 ft^2. Subtract 4000ft^2 by 150 ft^2 and you get 3850 ft^2

Answer:

d ≈ 87.85 yards

Step-by-step explanation:

The circumference ( C) of a circle is calculated as

C = πd ( d is the diameter ), then

276 = πd ( divide both sides by π )

[tex]\frac{276}{\pi }[/tex] = d , so

d ≈ 87.85 yards ( to the nearest hundredth )

Answer:the correct answer is C

Answer:

60% are girls

Step-by-step explanation:

80 x 1.5 = 120 which is the amount of girls

120 out of 200 is 12/20 or 3.5 which is 60%

Answer:

  C.  Residuals aren't random; linear is not a good fit

Step-by-step explanation:

The attached graph shows the given points (black) and the best-fit line (red). The residuals are connected by the dashed red line. They are decidedly NOT random. It appears that an exponential fit would work better than this linear fit.

The residual values are not randomly dispersed around the horizontal axis, so a linear fit is not appropriate.

Answer:

10 m building in Patrick's drawing would be of  0.5 cm

Step-by-step explanation:

Scale of Patrick's drawing is

1 inch = 10 meters

or 2.54 cm = 10 meters

1 cm = 3.94 m

In case of  Squidward the scale is 2 cm = 40 meters or

1 cm = 20 meters

So a 10 m building in Patrick's drawing would be of

0.5 cm

Answer:

13.5

Step-by-step explanation:  

Given: Patrick’s drawing uses a scale of 1 inch = 10 meters. Squidward made another scale drawing of the hotel with a scale of 2 cm = 40 meters.  

To find: How tall is the hotel on Squidward’s drawing?  

Formula: Height of the building = y × tan x + measurer's height  

Solution: The height of the building is calculated by using the formula. y = distance of the measurer from the building. x = the angle measured from the clinometer.

Answer:

∠1, ∠5 and ∠8  (a)

Step-by-step explanation:

∠1 because vertical angles are congruent

∠5 because opposite interior angles are congruent

if ∠5 = 70° then ∠8 also equals 70° because of vertical angles

Answer:

1 and 3

Step-by-step explanation:

vertical angles are opposite to each other when angles are created by intersecting lines.

Answer:

1 and 3 our the only vertical angles in this picture HOPE THAT HELPS!

Answer:

4

Step-by-step explanation:

Answer:

[tex]x=4\frac{11}{15}[/tex]

Step-by-step explanation:

- 62 = - 15(x - 1) + 4

- 52 = - 15x + 15 + 4

- 52 = - 15x + 19

- 52 - 19 = - 15x + 19 - 19

- 71 = - 15x

- 15x ÷ - 15 = - 71 ÷ - 15

[tex]x = \frac{71}{15}[/tex]

[tex]x=4\frac{11}{15}[/tex]

Answer:B.

Step-by-step explanation: Got it right on quiz.

Answer:

b.

stabilizing; disruptive

Step-by-step explanation:

Answer:

[tex] \frac{9i}{(9 - r)i} = 3024 \\ (9 - r)i = 9i \div 3024 = 362880 \div 3024 = 120 = \\ = 1 \times 2 \times 3 \times 4 \times 5 = 5i \\ r = 4[/tex]

Profit in 2006:  $7 million

First convert the percent into decimal: 9% = 0.09

Then use the percent increase then multiply by the number using this formula: ( 1 + r ) = ( 1 + 0.09) = 1.09

You only want to find how much profit in 2006, so you do this:

2003: 5.4  

2004: 5.4 (1.09) = 5.886  

2005: 5.886 (1.09) = 6.41574  

2006: 6.41574 (1.09) = 6.99316

Then you take 6.99316 and round to the nearest tenth of a million dollars.

7 million dollars.

Answer:

x = 38

∠P = 26º

Step-by-step explanation:

The sum of the angle in a triangle is 180

x + (x + 78) + (x - 12) = 180

Combine like terms

3x + 66 = 180

Subtract 66 from both sides

3x = 114

Divide both sides by 3

x = 38

-----------------------

∠P = x - 12

∠P = 38 - 12

∠P = 26º

Answer:

Step-by-step explanation:

(x+78)+(x-12)+x=180

3x+66=180

3x=114

x=38

P=26

Answer:

Hello! answer: x = 31

Step-by-step explanation:

This whole thing Will equal 360 we can subtract that by 112 and another 112 because there are two because they are vertical angles so 112 + 112 = 224 360 - 224 = 136 now we divide by 2 since those last two angles will have the same measure 136 ÷ 2 = 68 so now we just have to find out what multiplied by 2 plus 6 = 68 so 2 × 31 = 62 and 62 + 6 = 68 so x = 31 hope that helps! and I showed a visual for you so hopefully this makes more sense!

Answer:

The equation of any straight line, called a linear equation, can be written as: y = mx + b, where m is the slope of the line and b is the y-intercept. The y-intercept of this line is the value of y at the point where the line crosses the y axis.

Step-by-step explanation:

Answer:

Area = 115 yards

Step-by-step explanation:

If we look at this as two rectangles, you can see that the area of one is going to be 10yd multiplied by 9yd, which gives us 90yd. The other smaller rectangle will be 6yd multiplied by 4yd, which gives us 24yd.

Now, add the two areas back together to get the area of the whole shape and you get A=115yd.

Hope this helps!
