If 1 bag of soil will covers 5 square feet, the number of bags of soil that will cover Susie's 35 square feet triangular garden is 7 bags.

Option D) is the correct answer.

Area of a triangle is expressed as half base multiply by height.

A = (1/2)base × height

Given that;

A = (1/2)base × height

A = (1/2) × 7ft × 10ft

Area of the triangular garden A = 35ft²

Now, if 1 bag of soil covers 5 square feet. how many will cover 35 square feet?

1 bag covers 5ft²

x bags covers 35ft²

x = 35 / 5

x = 7 bags

Therefore,  if 1 bag of soil will covers 5 square feet, the number of bags of soil that will cover Susie's 35 square feet triangular garden is 7 bags.

Option D) is the correct answer.

Answer:

(a) 64°

(b) Yes, it is safe

Step-by-step explanation:

A fireman needs to get water to a second-floor fire. His ladder is 30 ft long and he leans it against the vertical wall so that the top of the ladder is 27 ft above the ground.

(a) Use trigonometry to find the angle formed between the ground and the ladder. Round to the nearest whole number and show all your work.

We solve the above question using the trigonometric function of Sine

sin θ = Opposite side/Hypotenuse sides

θ = Angle formed with the ground = ?

Opposite side = 27 ft

Hypotenuse side = 30 ft

Hence,

sin θ = 27 ft/30 ftsin θ = 9/10 = 0.9

θ = arc sin (0.9)

θ = 64.158067237°

Approximately to the nearest whole number = 64°

(b) For safety reasons, the fireman wants the angle the ladder makes with the ground to be no more than 70°.Will the ladder be safe the way it is positioned?

From the above calculation, the angle the ladder makes with the ground is 64° and now we want that angle to be 70°

Hence:

64° < 70°

Therefore, the ladder will be safe the way it is positioned.

Answer:

(a) 64°

(b) Yes, it is safe

For the first statement the converse is two angles are equal if the two angles are both obtuse, for second "x = -5 if the equation is  3 - 2x = 13" for third Two angles are not equal if 2 angles are supplementary.

A conditional statement with the antecedent and effect reversed is known as a converse statement.

We have statement:

1. If two angles are both obtuse, the two angles are equal.

Converse: The two angles are equal if the two angles are both obtuse.

2. If 3 - 2x = 13, then x = -5.

Converse: x = -5 if the equation is  3 - 2x = 13

3. If 2 angles are supplementary, then they are not equal.

Converse: Two angles are not equal if 2 angles are supplementary.

Thus, for the first statement the converse is two angles are equal if the two angles are both obtuse, for second "x = -5 if the equation is  3 - 2x = 13" for third Two angles are not equal if 2 angles are supplementary.

The distance between a and b is 5 units.

An equilateral triangle has three sides that have the same length. The triangle is defined as the plane two-dimensional figure with three sides having the sum of the three angles of 180 degrees.

Since the figure is missing in the question so I have attached the figure of the points on the graph for better understanding.

The given coordinates are as follows:-

a (-3, 2)

b (-6, -2)

c (0, -2)

Use the distance formula,[tex]d=\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}[/tex] , to find ab.

ab  = √[(−6−(−3))² + (−2−2)²]

ab  = √25

ab  = 5 units

Therefore the distance between A and B is 5 units.

3:64

4: 77

6: 3

7:12

8: O=110 X:110

Step-by-step explanation:

Number 2 shows what is called a central angle. Central Angles are equivalent to the ark length

Number 3 shows an Inscribed angle. These angles are half of the ark but in your question, it is twice the angle measurement

Number 4 you want to divide the ark length by two when the angle is not given. And when the angle is given you want to mutilate by two

Number 6 is Overlapping Ark which means they are both congruent to each other because the ark is equivalent to each other.

Number 7 is x=12 because 5x+12 is twice the measure of 3x

Number 8 o=110 because a circle has 360 degrees so you want to add them up and then subtract that from 360. x is also 110 degrees because it is a central angle, which is the same amount of degrees as the ark length.

The area of the shaded region or portion in the circle is (25π - 24) cm².

The area of the shaded portion in the circle is found by subtracting the area of the two triangles from the area of the circle.

Therefore,

area of the circle = πr²

where

area of a triangle = 1/ 2 bh

where

Therefore,

r = 5 cm

area of circle = 5²π = 25π cm

area of one triangle = 1 / 2 × 6 × 4 = 12 cm²

The area of the two triangles = 2(12) = 24 cm²

Given:

[tex]\boxed{\text{Midpoint of a line segment:} \ \huge\text(\dfrac{x_1 + x_2}{2} ,\dfrac{y_1 + y_2}{2} \text)}[/tex]

Substitute the endpoints of the line segment in the midpoint:

Simplify the coordinates in the midpoint:

[tex]\implies \huge\text[\dfrac{-2 - 4}{2} ,\dfrac{6 - 9}{2} \text] \implies \huge\text[\dfrac{-6}{2} ,\dfrac{-3}{2} \text]\implies \huge\text[-3 ,-1.5 \text][/tex]

The volume of the stump in cubic inches is 18095.6  if the Ashley measures its height as 1.2 ft and its radius as 20 in.

In geometry, it is defined as the three-dimensional shape having two circular shapes at a distance called the height of the cylinder.

We know the volume of the cylinder is given by:

[tex]\rm V = \pi r^2 h[/tex]

We have h = 1.2 ft = 1.2×12 = 14.4 inches

r = 20 inches

[tex]\rm V = \pi (20)^2 \times 14.4[/tex]

After calculating, we get:

V = 18095.57 ≈ 18095.6 cubic inches

Thus, the volume of the stump in cubic inches is 18095.6  if the Ashley measures its height as 1.2 ft and its radius as 20 in.
