Step-by-step explanation:

-1 + 6(-1 - 3x) > -39 - 2x

-1 - 6 - 18x > -39 - 2x

-7 - 18x > -39 - 2x

32 > 16x

Answers

Answer:

x = -3.5

Step-by-step explanation:

−2.4x=8.4

Divide both sides by −2.4.

x= 8.4/-2.4

Expand 8.4/-2.4 by multiplying both numerator and the denominator by 10.

x= 84/-24

Reduce the fraction 84/-24 to lowest terms by extracting and canceling out 12.

Which of the following numbers
could be the absolute value of
another number?
A -425
B 1,200
C -1,300
D-2,525

Answers

Answer:

Step-by-step explanation:

Essentially, recall what an absolute value function is.

When you plug number into an absolute value function, or make it an absolute value, you will ALWAYS get a positive version of that number.

When the question asks, what number could be the absolute value of another number, it's asking you what is a possible outcome of making a number an absolute value.

Since we know that making any number an absolute value, makes that number positive. We can get rid of all of the negative answers.

You are left with B.

Answer:

B. 1200

Step-by-step explanation:

Absolute value is the non-negative version of a number/variable. Whether the sign is negative or positive, the absolute value is always positive.

|-4|=4

The cone shaped roof has the height of 30ft and the radius of 15ft find it's lateral area and the surface area

Answers

Answer:

Lateral surface area of cone is 1580 feet²Surface area of cone is 2287 feet²

[tex]\\[/tex]

Step-by-step explanation:

Given that Height of cone shaped roof is 30 ft and radius is 15 ft.

To calculate the lateral surface area and Surface area of the cone we will use the formula given below:

[tex]\\[/tex]

[tex]\star \: { \underline { \boxed { \purple{ \pmb { \sf{Lateral \: surface \: Area _{(cone)} = \pi rl}}}}}}[/tex]

[tex]\\[/tex]

[tex]\star{\underline{ \boxed{ \purple{ \pmb { \sf{Surface \: area _{(cone)} = \pi rl + \pi {r}^{2} }}}}}}[/tex]

[tex]\\[/tex]

Finding the Slant height of the cone:

[tex]\dashrightarrow \: \:L = \sqrt{ {(r)}^{2} + {(h)}^{2} } \\ [/tex]

[tex] \dashrightarrow \: \: L = \sqrt{225 +900 } \\ [/tex]

[tex] \dashrightarrow \: \: L = \sqrt{1125 } \\ [/tex]

[tex]{ \dashrightarrow \: \: { \pink{ \boxed { \: L = 33.541 }}}}\\ [/tex]

Hence, Slant height of cone is 33.54 feet.

Substituting values in above formula:

[tex]\dashrightarrow \: \: LSA = \pi rl \\ [/tex]

[tex]\dashrightarrow \: \: LSA = \dfrac{22}{7} \times 15 \times 33.54 \\ [/tex]

[tex]\dashrightarrow \: \: LSA = \dfrac{22 \times 15 \times 33054}{7} \\ [/tex]

[tex]\dashrightarrow \: \: LSA = \dfrac{11068.2}{7} \\ [/tex]

[tex]\dashrightarrow \: \:{ \boxed { \pmb{ \sf {\pink{ LSA \: \approx1580 \: {ft}^{2}}}} }} \\ [/tex]

[tex]\\[/tex]

Hence, Lateral surface area of cone is 1580 feet²

Now, Calculating surface area:

[tex]\dashrightarrow \: \:SA = \pi rl + \pi {r}^{2} \\ [/tex]

[tex]\dashrightarrow \: \:SA = \pi (15)(33.54) + \pi {(15)}^{2} \\ [/tex]

[tex]\dashrightarrow \: \:SA = \pi(503.1) + 22 5 \pi \\ [/tex]

[tex]\dashrightarrow \: \: SA = 728.1 \pi \\ [/tex]

[tex]\dashrightarrow \: \:SA = 728.1 \times 3.14 \\ [/tex]

[tex]\dashrightarrow \: \:{ \boxed{ \pmb{ \pink{ \sf{SA \approx2287 \: {ft}^{2} }}}}} [/tex]

[tex]\\[/tex]

Hence, surface area of cone is 2287 feet²

How to write the slope intercept equation for points of (6,0) and (0,-5)?

Answers

Answer:

[tex]y=\frac{5}{6} x -5[/tex]

Step-by-step explanation:

Hi there!

We are given the points (6,0) and (0, -5), and we want to write the equation of the line containing those points in slope-intercept form

Slope-intercept form can be written as y=mx+b, where m is the slope and b is the y intercept

First, we need to find the slope of the line

The formula for the slope can be written as [tex]\frac{y_2-y_1}{x_2-x_1}[/tex], where [tex](x_1, y_1)[/tex] and [tex](x_2, y_2)[/tex] are points

We have everything we need to find the slope, but let's label the points to avoid confusion

[tex]x_1=6\\y_1=0\\x_2=0\\y_2=-5[/tex]

Now substitute these values into the formula

m=[tex]\frac{y_2-y_1}{x_2-x_1}[/tex]

m=[tex]\frac{-5-0}{0-6}[/tex]

Subtract

m=[tex]\frac{-5}{-6}[/tex]

Simplify

m=[tex]\frac{5}{6}[/tex]

The slope of the line is 5/6

Let's plug this value into the formula for the equation of the line in slope-intercept form.

We substitute 5/6 for m in y=mx+b:
y=[tex]\frac{5}{6}x+b[/tex]

Now we need to find b

As stated before, b is the y intercept, which is the value where the line hits the y axis. The value of x at the y intercept is 0.

One of the points we were given is actually the y intercept; that point is (0, -5); notice how the value of x in this point is 0

The value of b is the value of y in this point, which is -5 in this case.

Substitute -5 as b in the formula.

[tex]y=\frac{5}{6} x -5[/tex]

Hope this helps!

A hot air balloon is launched from the ocean beach. As it moves inland, it rises and then falls, having a path given by
p(x)= - 2x^2/2500 +0.7x where x is in metres. The land rises at a rate of 2 vertical metres for each 20 horizontal metres. See the

b. What is the maximum height of the balloon above seal level?
c. What is the maximum height of the balloon above ground level?
m and
d. At what horizontal distance is the balloon 50 m above the ground? List the smaller value first.

Answers

The launching of the hot air balloon is from the ocean beach is an illustration of a projectile motion

The horizontal distance which it attains a maximum height

The function is given as:

[tex]p(x) =-\frac{2}{2500}x^2 + 0.7x[/tex]

Differentiate

[tex]p'(x) =-\frac{4}{2500}x + 0.7[/tex]

Set to 0

[tex]-\frac{4}{2500}x + 0.7 = 0[/tex]

Subtract 0.7 from both sides

[tex]-\frac{4}{2500}x =- 0.7[/tex]

Multiply through by -2500/4

[tex]x =437.5[/tex]

Hence, the horizontal distance which a maximum height is attained is 437.5 meters

The maximum height above the sea level

In (a), we have:

[tex]x =437.5[/tex]

Substitute [tex]x =437.5[/tex] in p(x)

[tex]p(437.5) =-\frac{2}{2500} * 437.5^2 + 0.7 * 437.5[/tex]

Evaluate

[tex]p(437.5) =153.125[/tex]

Hence, the maximum height above the sea level is 153.125 metres

The maximum height above the ground level

In (b), the maximum height above the sea level is 153.125 metres

The ratio of the height on land and sea is given as:

Land : Sea = 2 m : 20 m

For the maximum height, we have:

Land : 153.125 m= 2 m : 20 m

Express as fraction

Land / 153.125 m = 2 /20

Multiply both sides by 153.125

Land = 15.3125

Approximate

Land = 15.3

Hence, the maximum height above the ground level is 15.3 meters

The horizontal distance where the balloon 50 m above the ground

We have:

[tex]p(x) =-\frac{2}{2500}x^2 + 0.7x[/tex]

Substitute 50 for P(x)

[tex]-\frac{2}{2500}x^2 + 0.7x = 50[/tex]

Using a graphing calculator, we have:

x = 78.465 and 796.535

Hence, the horizontal distances where the balloon 50 m above the ground are 78.465 and 796.535 meters

The volume of water contained in this aquarium that is filled halfway through its height is equal to 141,750 cm³.

The volume of a right prism.

Mathematically, the volume of a right prism is calculated by using this formula:

Volume = length × width × height

Given the following data:

Length = 45 cm.Width = 90 cm.Height = 70 cm.

Based on the information, the aquarium is filled halfway through its height. Thus, the height of water is given by:

H = 70 × 0.5

H = 35 cm.

Substituting the parameters into the formula, we have;

Volume = 45 × 90 × 35

Volume = 141,750 cm³.

How to calculate the volume?

Mathematically, the volume of Elisha's swimming pool is given by:

Volume = length × width × height

Volume = 10 × 5 × 1

Volume = 50 m³.

Now, we can calculate the cost of water supply:

Cost = 27.25 × 50 × 10³

Cost = P1,362,500.

How to calculate the volume of water.

Mathematically, the volume of a rectangular prism is given by this formula:

Volume = length × width × height

Volume = 130 × 70 × 110
