Answer:

Imani's rent had a higher percent increase

Step-by-step explanation:

A change from 560 to 600 represents a positive change (increase) of 7.1428571429%

A change from 825 to 875 represents a positive change (increase) of 6.0606060606%

Percent change = New - Old /825 × 100

Answer:

surface area = 245.04 cm² (nearest tenth)

Step-by-step explanation:

Surface area of a closed cylinder = [tex]2\pi r^2+2\pi rh[/tex]

Given:

⇒ surface area = 2 × [tex]\pi[/tex] × 3² + 2 × [tex]\pi[/tex] × 3 × 10

                          = 78[tex]\pi[/tex]

                          = 245.04 cm² (nearest tenth)

Step-by-step explanation:

Answer:

Approximately [tex]58.2\; \text{nautical miles}[/tex] (assuming that the bearing is [tex]{\rm S$29^{\circ}$W}[/tex].)

Step-by-step explanation:

Let [tex]v[/tex] denote the speed of the ship, and let [tex]t[/tex] denote the duration of the trip. The magnitude of the displacement of this ship would be [tex]v\, t[/tex].

Refer to the diagram attached. The direction [tex]{\rm S$29^{\circ}$W}[/tex] means [tex]29^{\circ}[/tex] west of south. Thus, start with the south direction and turn towards west (clockwise) by [tex]29^{\circ}[/tex] to find the direction of the displacement of the ship.

The hypothenuse of the right triangle in this diagram represents the displacement of the ship, with a length of [tex]v\, t[/tex]. The dashed horizontal line segment represents the distance that the ship has travelled to the west (which this question is asking for.) The angle opposite to that line segment is exactly [tex]29^{\circ}[/tex].

Since the hypotenuse is of length [tex]v\, t[/tex], the dashed line segment opposite to the [tex]\theta = 29^{\circ}[/tex] vertex would have a length of:

[tex]\begin{aligned}& \text{opposite (to $\theta$)} \\ =\; & \text{hypotenuse} \times \frac{\text{opposite (to $\theta$)}}{\text{hypotenuse}} \\ =\; & \text{hypotenuse} \times \sin (\theta) \\ =\; & v\, t \, \sin(\theta) \\ =\; & v\, t\, \sin(29^{\circ})\end{aligned}[/tex].

Substitute in [tex]\begin{aligned} v &= 20\; \frac{\text{nautical mile}}{\text{hour}}\end{aligned}[/tex] and [tex]t = 6\; \text{hour}[/tex]:

[tex]\begin{aligned} & v\, t\, \sin(29^{\circ}) \\ =\; & 20\; \frac{\text{nautical mile}}{\text{hour}} \times 6\; \text{hour} \times \sin(29^{\circ}) \\ \approx\; & 58.2\; \text{nautical mile}\end{aligned}[/tex].

Answer:

1:8

Step-by-step explanation:

Answer:

1:8

Step-by-step explanation:

Here , 2.5:20

or 25/10:20

or 25:200(Multiplying by 10)

or 1:8(Dividing both sides with 25)

Answer:

B

Step-by-step explanation:

This is because both the denominator and numerator of 3/4 is negative, so the whole fraction is technically negative. Having that symbol ( - ) in front of it also means the whole fraction is negative. It's the same thing.

Answer:

B

Step-by-step explanation:

Stopping at a stoplight means that Chris's speed would be zero on the graph. The times that his speed is zero are times t = 0, t = 2 min, t = 11 min, and t = 21 min. Because the graph shows his speed from the time he left his house (at t = 0) to the time he arrived at the theater (at t = 21 min), the most likely times he stopped at stoplights are times t = 2 min and t = 11 min.

Answer: to find the answer you need to

Step-by-step explanation:

Create a table with headings n and an where n denotes the set of consecutive positive integers, and an represents the term corresponding to the positive integers. You may pick only the first five terms of the sequence. For example, tabulate the series 5, 10, 15, 20, 25, . . .

Solve the first common difference of a. Consider the solution as a tree diagram. There are two conditions for this step. This process applies only to sequences whose nature are either linear or quadratic.Condition 1: If the first common difference is a constant, use the linear equation ax + b = 0 in finding the general term of the sequence.

Answer:

Step-by-step explanation:

|| ▼ Answer ▼ ||

Option (A) 4 x + 89.95 = 628.35; x = 134 dollars and 60 cents

|| ✪ Solution ✪ ||

Total cost of the trip was $628.35, Anja paid $89.95 as a flat fee, and paid extra for the four tooth fillings, the equation that represents this situation is:

[tex]4x+89.95=628.35-- > (1)[/tex]

The solution to equation (1) is as follows:

[tex]4x=628.35-89.95=538.4[/tex]

[tex]x=\frac{538.4}{4} =134.6[/tex]

[tex]x=134.6[/tex]

x = $134 and 60 cents

Conclusion: The answer is Option (a).

Hope this helps!

Answer:

Undefined

Step-by-step explanation:

It is undefined because the x value equals multiple y values so the slope is undefined :)

Have a great day!!

Please rate and mark brainliest!!

Answer: Choice B

Undefined

Reason:

Vertical lines always have undefined slopes.

This is because slope = rise/run, but run = 0 for vertical lines. The "run" describes how much the line moves to the right, but such a thing doesn't happen since it's stuck on one x value only.

So we could have something like slope = rise/run = 1/0 = undefined. Dividing over zero is not allowed.

Answer: -0.1, 0, 0.8, 1.2, 1.6

Step-by-step explanation:

think of numbers on a line with zero in the middle, the numbers would be to the right, positive and inclining, to the left, negative and decreasing, when you throw decimals into the list, you organize them from least to greatest like normal numbers, but the normal numbers are always.

Answer:

The correct option is;

D. g(-13) = 20

Step-by-step explanation:

The given information are;

The domain of the function, g is given as -20 ≤ x ≤ 5

The range of the function, g(x), is given as -5 ≤ g(x) ≤ 45

g(0) =-2 and g(-9) = 6

Therefore, given that the function increases from -2, to 6 as the input variable decreases from 0 to -9

Therefore, if the variable, x, decrease further, to -13, the function will likely increase further, to about 20, while in the variable, x, increases further, to 7, the function may likely decrease to about -1

Therefore, we can get either;

g(-13) = 20 or g(7) = -1

However, the domain of the function is -20 ≤ x ≤ 5, therefore, 7 is outside the domain, giving g(-13) = 20 as the only statement that could be true

1st question : volume to be filled in liter ?

V cone = 1/3 x base area x h

            = 1/3 x pi x r² x h

            = 1/3 x 3,14 x (30:2)² x 30

            = 1/3 x 3,14 x 15² x 30

V cone = 7,065 cm3 ≈ 7 dm3 ≈ 7 liters

then

we know                         4 liters .............1 minute

we are looking for          7 liters............. n minute

4 x n = 7 x 1

n = 7/4

n = 1,75 min => = 1 min + 0,75x60 = 1 min and 45 sec

Answer:

(x² - 3)(x² + 3)([tex]x^{4}[/tex] + 9)

Step-by-step explanation:

[tex]x^{8}[/tex] - 81 ← is a difference of squares and factors in general as

a² - b² = (a - b)(a + b)

[tex]x^{8}[/tex] - 81

= ([tex]x^{4}[/tex] )² - 9²

= ([tex]x^{4}[/tex] - 9)([tex]x^{4}[/tex] + 9) ← [tex]x^{4}[/tex] - 9 is also a difference of squares

= (x² - 3)(x² + 3)([tex]x^{4}[/tex] + 9)

Answer:B

Step-by-step explanation:

(x2 − 3)(x2 + 3)(x4 + 9)

Answer:

2 cans of paint

Step-by-step explanation:

Surface area of an open cylinder = [tex]2\pi rh[/tex]

(where r is the radius and h is the height)

⇒ SA = 2 × [tex]\pi[/tex] × (15 ÷ 2) × 10 = 150[tex]\pi[/tex] ft²

Surface area of an open cone = [tex]\pi r\sqrt{h^2+r^2}[/tex]

(where r is the radius and h is the height)

⇒ SA = [tex]\pi[/tex] × (15 ÷ 2) × √(4² + 7.5²) = 63.75[tex]\pi[/tex] ft²

Total surface area = 150[tex]\pi[/tex] + 63.75[tex]\pi[/tex] = 213.75[tex]\pi[/tex] = 671.52 ft² (nearest hundredth)

If one can of paint covers approx. 400 ft² then 2 cans of paint needed to cover 671.52 ft²
