Can two obtuse angles be supplementary? Why or why not?

Answers

Answer 1

Answer:

No.

Step-by-step explanation:

Two Angles are Supplementary when they add up to 180.

Let us consider the least obtuse angle, i.e., >90

Say 91 and add it to itself.

91+91 =182

This is >180

Hence, two obtuse angles can never be supplementary.

A 12-foot ladder is leaning against a wall. The bottom of the ladder is 5 feet away from the bottom of the wall.

Approximately how high up the wall does the top of the ladder reach?

Answers

Answer:

10.9 units

Step-by-step explanation:

Let the hight of the wall be " x ".

( Height = x )

Here,

12 foot ladder is the hypotenuse side.

( Hypotenuse = 12 )

5 feet away is the base side.

( Base = 5 )

Formula : -

Height² + Base² = Hypotenuse²

x² + 5² = 12²

x² + 25 = 144

x² = 144 - 25

x² = 119

x = √119

x = 10.9 approximately

Therefore,

High up the wall does the top of the ladder reach is 10.9 units.

Which is a larger volume, a candle with a height of 6. 3 inches and a radius of 3. 1 inches, or a candle with both a height and a radius of 3. 9 inches?

Answers

Working out:
H = height
R = Radius
A = area

Volume of a cylinder = A x H

Area of circle = Pi x (R^2)

Label the candles, Candle X and Candle Y

(X being the one with 3.1 inches and Y being the one with 3.9)

*CANDLE X*
3.1 x 3.1 = 9.61
9.61 x pi (3.14) = 30.1754
30.1754 x H (6.3) = 190.10502cm^3

*CANDLE Y*
3.9 x 3.9 = 15.21
15.21 x pi (3.14) = 47.7594
47.7594 x H (3.9) = 186.26166cm^3

CANDLE X HAS THE LARGER VOLUME BY 3.84336CM^3

If it is false, explain why you know that it is false and change the statement to a true statement.
{(3,6), (4,6), (5,7), (6,8), (7,10), (8,10)
Statement 1:
The relation is not a function because every y-value has more than one corresponding X-value
Statement 2:
The domain of this relation is 3=< x =< 8.
Statement 3:
The range of this relation is {6, 7, 8, 10}

Answers

Answer:

Statement 1 - false

A function is one-to-one or many-to-one.

One-to-one means each value in the range (y-values) corresponds to exactly one value in the domain (x-values)

Many-to-one means some values in the range (y-values) correspond to more than one (many) value in the domain (x-values).

Therefore, as some y-values correspond to more than one x-value, this is a many-to-one function.

The true statement should be:

The relation is a function because some y-values correspond to more than one x-value.

Statement 2- true

The domain is the set of input values (x-values).  Therefore, the domain is 3 ≤ x ≤ 8 as the smallest x-value is 3 and the highest x-value is 8.

Statement 3 - true

The range is the set of output values (y-values).  Therefore, the range is {6, 7, 8, 10} as these are the y-values of the ordered pairs.

The depth of two lakes is measured at multiple spots. For the first lake, the mean depth is about 45 feet with a mean absolute deviation of 8 feet. For the second lake, the mean depth is about 60 feet with a mean absolute deviation of 27 feet.


Noah says the second lake is generally deeper than the first lake. Do you agree with Noah?



No, I do not agree with Noah because the second lake has greater variability with a higher MAD so even though the mean depth is deeper the data is very spread out away from that mean.


No, I do not agree with Noah. The MAD tells us how deep it is and the 1st MAD is more.


Yes, I agree with Noah. The MAD tells us how deep it is and the second MAD is more.

Two theorems we are proving are:

Line drawn from the center of the circle to bisect a chord is perpendicular to it.Perpendicular drawn from the center of the circle to a chord, bisects it.

How do we solve the given question?

Part A: The image is attached

Part B:

Let there be a circle with the center at O. Let AC be a chord. Let OE be a radius of the chord such that OE bisects AC at B, that is, AB = BC.

To prove: A line drawn from the center of the circle to bisect a chord is perpendicular to it.

Construction: We join OA and OB.

Proof:

In ΔOAB and ΔOCB,

OA = OC (Radius of the same circle)

AB = BC (Given, at B, the chord is bisected)

OB = OB (common side)

∴ ΔOAB ≅ ΔOCB [SSS axiom]

∴ ∠OBA = ∠OBC [Common parts of Congruent triangles]

Let ∠OBA = ∠OBC = x.

Since AC is a straight line,

∠OBA + ∠OBC = 180° [Linear pair]

or, x + x = 180°

or, 2x = 180°

or, x = 90°.

∴ ∠OBA = ∠OBC = 90°.

So, we can say that OB ⊥ AC, hence the theorem is proved.

Part C: The image is attached

Part D:

Let there be a circle with the center at O. Let AC be a chord. Let OE be a radius of the chord such that OE is perpendicular to AC at B, that is, AB ⊥ BC.

To prove: A line drawn from the center of the circle perpendicular to the chord bisects it.

Construction: We join OA and OB.

Proof:

In ΔOAB and ΔOCB,

OA = OC (Radius of the same circle)

∠OBA = ∠OBC = 90° (∵ OB ⊥ AC)

OB = OB (common side)

∴ ΔOAB ≅ ΔOCB [RHS axiom]

∴ AB = AC [Common parts of Congruent triangles]

So, we can say that OE perpendicular to the chord AC bisects it, hence the theorem is proved.

what is an equation of the line that passes through the point (-2,-8) and has a slope of 3?

a) y=3x-2
b) y=3x-22
c) y=3x+2
d) y=3x+22

Answers

Answer:

y = 3x -2

Step-by-step explanation:

General equation of a line in the slope intercept form is

y = mx + b ,

where m is the slope and b is the y-intercept ( where intercepts the y-axis)

y = 3x + b ,

because is given slope is m = 3

For point (x = -2, y = -8) we have

-8 = 3 (-2) + b

-8 = -6 + b

-8 + 6 = b

-2 = b

Mrs. Nigrini picks up some grapefruits that each weigh 1/2 pound. When she checks out she finds her bag of grapefruit weighs exactly 6.5 pounds. Each grapefruit costs $1.29. How much did she spend on grapefruit?

Answers

Answer:

A cube is a rectangular prism where all its sides are the same. The formula to find the surface area of a rectangular prism is A = 2wl + 2lh + 2hw, where w is the width, the l is the length, and the h is the height.

The surface area formula for a cube is 6l²

How to determine the surface area?

A cube has the following features:

6 faces of equal areasEach face has equal side length

The area of a face of a cube is:

Area = l²

Where l represents the side length

The surface area formula for a cube is then calculated using:

Surface area = 6 * Area of a face
