8. What is the surface area of the pyramid
shown below?

Answer:

7.415 ≤ x < 7.425

Step-by-step explanation:

The number x was rounded to 2 decimal places to give 7.42.

Since rounded off to 2 decimal places, the error interval for x is half of 0.01 subtracted from and added to 7.42.

Thus;

7.42 ± (0.01/2)

(7.42 - 0.005),(7.42 + 0.005)

7.415, 7.425

Now, 7.425 will not be included in the internal because approximating it doesn't give 7.42.

Thus,the error interval is;

7.415 ≤ x < 7.425

Answer: 6.3

Step-by-step explanation:

Answer:

1. sin and cos  2. complementary  3. sinA = cosB  4. 80°  5. 17

Step-by-step explanation:

1. cofunctions: having the same value at complementary angles

sin θ = cos (90 - θ), or  cos θ = sin(90 - θ)

2. complementary: two angles sum to 90°, supplementary: two angles sum to 180°

one of the angle in a right triangle must be a right angle = 90°

180°(sum of angles of a triangle) - 90° = 90°(the sum of the other two angles) => which is complementary

3. sinA = cosB

4. cos θ = sin(90 - θ)

=> cos 10° = sin(90 - 10°)

=> cos 10° = sin(80°)

5. sin θ = cos (90 - θ)

=> sin 73° = cos (90 - 73°)

=> sin 73° = cos (17°)

Answer:

f(-3) = 6

Step-by-step explanation:

This question asks one to evaluate the function (f) for input (-3). It is known that the x-axis represents the input, while the y-axis represents the output. Therefore, find (-3) on the x-axis, and then see where the graph of the line is when it meets the value (-3), this value will be the output. In this case, the output is (6).

Answer:

$183.3

Step-by-step explanation:

Ruth uses healthy credit to finance $2,200 for a hearing aid how much would she have to pay each month to pay back the loan in exactly 1 year

Ruth took a loan of $2,200

1 year = 12 months

Hence, the amount she would be paying monthly is calculated as:

$2,200/12 months

= $2,200/12

= $183.33333333

Approximately = $183.3

Therefore, Ruth would be paying $183.3 monthly.

Answer:

Answer:

a=55

b=55

c=125

d=125

e=55

f=55

g=125

Step-by-step explanation:

Answer:

∠a = 55°, ∠b = 55°, ∠c = 125°, ∠d = 125°, ∠e = 55°, ∠f = 55°, ∠g = 125°

Step-by-step explanation:

straight lines form 180°:

125° + ∠a = 180°

=> ∠a = 55°

verticle angles are congruent:

∠c = 125°

∠b ≅ ∠a => ∠b = 55°

When two line are parallel:

same side interior angles are congruent:

∠g ≅ ∠c => ∠g = 125°

∠e ≅ ∠a => ∠e = 55°

∠d = 125°

∠ f ≅ ∠b => ∠f = 55°

Answer:

The correct answer is 60/100.

Step-by-step explanation:

6 x 10 is 60 so all you have to do is add 100 as the denominator so that's why I got 60/100 Thank you!

A fraction is a way to describe a part of a whole. The fraction is equivalent to 6/10 and has a denominator of 100 is 6/10.

A fraction is a way to describe a part of a whole. such as the fraction ¼ can be described as 0.25.

The fraction is equivalent to 6/10 and has a denominator of 100 will be,

6/10

Multiply both the numerator and the denominator by 10.

Answer:

Each piece of cloth is (1/12) of a yard long.

Step-by-step explanation:

Carlus cut 5/12 of a yard of cloth into 5 pieces of equal length.

To find the length of each piece of cloth, we need to find the quotient between the length of the piece of cloth, and the number of pieces in which we divide it.

This is:

length = [tex]\frac{(5/12)yd}{5} = \frac{5yd}{12*5} = \frac{1yd}{12} \frac{5}{5} = \frac{1 }{12} yd[/tex]

This means that the length of each piece of cloth is (1/12) of a yard long.

Answer:

D

Step-by-step explanation:

Firstly, the question is phrased very very badly as the four answers provided are coordinate points rather than how far apart the cities are in units.

To calculate the distance between two points, we have to use Pythagoras' Theorem as it's just pretty much a right-angle triangle. Please look at the (terribly drawn) image provided.

Keep in mind that these points are only roughly placed on the map.

But firstly, to use Pythagoras' Theorem (a^2 + b^2 = c^2), we must find the length of the two sides.

To find the length of the horizontal line (which from now on I'll refer to as 'a'), we must subtract the smaller x value from the larger one.

47 - 35 = 12

To find the length of the vertical line (which from now on I'll refer to as 'b'), we must subtract the smaller y value from the larger one.

122 - 78 = 44

I assume that the answer you should pick is D. (12, 44)

However, that doesn't exactly answer the question... it's worded a little weirdly.

To solve the rest of the equation, do the following:

Now that we know that the length of a = 12 and the length of b = 44, we can use Pythagoras' Theorem.

a^2 + b^2 = c^2

12^2 + 44^2 = c^2

144 + 1936 = c^2

2080 = c^2

c = [tex]\sqrt{2080}[/tex]

c = 45.61

The answer is 45.61 units.

Answer:

73.12 ft²

Step-by-step explanation:

area = (8 x 6) + [(1/2)(3.14)(4²)] = 73.12 ft²

The average speed of the car for the given distance is 91.97 km/hr.

While both speed and velocity are indicators of how quickly an object is travelling, they serve different purposes. The distance travelled in a given amount of time, independent of direction, is referred to as speed, which is the magnitude of the velocity vector. In contrast, velocity is a vector quantity that accounts for both speed and direction. It is measured in units of distance per unit of time in a particular direction and is defined as the rate of change of position of an item with regard to a frame of reference.

Given that, a car started 35 minutes later that is it started after:

35 minutes = 35/60 = 0.5833 hours

Now the distance is given as:

distance = speed x time

Now, for speed = 65 km/hr:

distance = 65t

For the car the time is (t - 0.5833) thus:

distance = speed x time

130 = speed x (t - 0.5833)

Now for speed we have:

30 = s x (t - 0.5833)

130 = st - 0.5833s

130 + 0.5833s = st

130/s + 0.5833 = t

Now, substituting the value of t in the equation of the van we have:

distance = 65t

distance = 65(130/s + 0.5833)

130/s + 0.5833 = distance/65

130/s + 0.5833 = distance/65

130/s + 0.5833 = 130/65

130/s + 0.5833 = 2

s = 91.97km/hr

Hence, the average speed of the car for the given distance is 91.97 km/hr.
