WILL GIVE BRAINLIEST PLEASE HELP!

Multiplying a negative number by a negative number will give you a positive product.

When multiplying two negative integers, it comes out as positive.

For example, we are given the equation -4 * -4.

Using the rule [ -(-a) = a ], the answer for the equation is 16.

Best of Luck!

Question:

Howard is designing a chair swing ride. The swing ropes are 4 meters long, and in full swing they tilt in an angle of 23°. Howard wants the chairs to be 3.5 meters above the ground in full swing. How tall should the pole of the swing ride be? Round your final answer to the nearest hundredth.

Answer:

7.18 meters

Step-by-step explanation:

Given:

Length of rope, L = 4 m

Angle = 23°

Height of chair, H= 3.5 m

In this question, we are to asked to find the height of the pole of the swing ride.

Let X represent the height of the pole of the swing ride.

Let's first find the length of pole from the top of the swing ride. Thus, we have:

[tex] cos \theta = \frac{h}{L} [/tex]

Substituting figures, we have:

[tex] cos(23) = \frac{h}{4} [/tex]

Let's make h subject of the formula.

[tex]h = 4cos(23) = 3.68 [/tex]

The length of pole from the top of the swing ride is 3.68 meters

To find the height of the pole of the swing ride, we have:

X = h + H

X = 3.68 + 3.5

X = 7.18

Height of the pole of the swing ride is 7.18 meters

Answer:

x = 14

Step-by-step explanation:

As the triangle was dilated, all its sides increased by the same ratio.

So, as one side was 3 and then increased to 9, the ratio is:

ratio = 9 / 3 = 3

So, using this same ratio for the other side given, we can find the value of x.

The larger side of length x+1 is 3 times greater than the small side of length 5:

x + 1 = 3 * 5

x + 1 = 15

x = 14

C: 14

Answer:grjjrd

Step-by-step explanation:fdfgdjj

Answer: x = 1

Step-by-step explanation: When we have this kind of setup, we want to put our variables together on one side of the equation and our numbers together on the other side of the equation.

So first, let's put our variables together on the left side

by subtracting 2x from both sides of the equation.

That gives us 3x + 9 = 12.

Now we can move our numbers to the right by

subtracting 9 from both sides and we get 3x = 3.

Now divide both sides by 3 and x = 1.

Answer:

D) as x approaches neg. infinity, y approaches neg. infinity

Step-by-step explanation:

This is because you get to negative x infinity which is towards the right, you see that the y value is going down sharply as well towards the direction of negative infinity in y direction (x direction is right to left and y direction is up and down)

Answer:

s = [tex]\sqrt{81\\[/tex] in.

Step-by-step explanation:

The last two answer don't fit into the given equation, leaving the first two.  For the first one, you do not use the square root of a number that is being squared. That's like saying you're going to fix a car, but the car is just fine and doesn't need fixed.

If you're at all curious about what the square root of 81 is, it's 9.

Step-by-step explanation:

Answer:

4/663

Step-by-step explanation:

1/13 = probability of ace (as 1st card)

4/51 = probability of jack (as 2nd card) -->

4/663

The probability that the first card is an Ace and the second card is a Jack without replacement will be 0.00603318 or 4/663.

The probability of an event occurring is defined by probability.

Probability is also known as chance because, if you flip a coin, the likelihood that it will land on its head or tail is nothing more than the chance that either the head or the tail will occur.

In our daily time, there are several instances in the everyday world where we may need to draw conclusions about how everything will turn out.

Without replacement will be dependent events.

Probability of dependent events

P(A and B) = P(A) × P(B/A).

Probability of the first card as  Ace = 4/52 ( 4 are Aces out of 52 cards)

Probability of the second card as jack = 4/51 ( since 1 ace has been removed)

P( Ace and Jack ) =  4/52 ×  4/51 = 4/663 = 0.00603318

Hence the probability that the first card is an Ace and the second card is a Jack will be 0.00603318.

Step-by-step explanation:

Answer:

y=x-2

Step-by-step explanation:

the equation for slope intercept is y=mx+b, where m is the slope and b is the y intercept. The y intercept is -2, (where the line comes in contact with the x axis) and the slope is determined from the equation y2-y1/x2-x1 (rise over run) With this, we can see the slope is 1. hope this helps

Answer:

a) 0.09

b) 2 ways

Step-by-step explanation:

a) Probability Pedro's shot will score will be given as) :

P(score) = 0.30

The probability he will score in 2 consecutive shots will be calculated as:

P(score) * P(score)

= 0.30 * 0.30

= 0.09

Therefore, probability he will score in 2 consecutive shots is 0.09

b) Jillian has 3 bracelets: X, Y, & Z as a gift. If bracelet Y is chosen first, the number of ways Jillian can give out the bracelets since bracelet Y is chosen first, she will have 2 bracelets remaining. So, number of ways to distribute these 2 bracelets are :

= 2!

= 2 * 1

= 2

Which could be in this order:

YXZ or YZX

Therefore, the number of ways if Y is chosen first is = 2 ways

Answer: A. 0.09

Answer:

the volume of the pipe is 649.98 cubic inches.

Step-by-step explanation:

We have been given that a collar of Styrofoam is made to insulate a pipe. We are asked to find the volume of the given pipe.

We will use volume of hollow cylinder formula to solve our given problem.

[tex]\text{Volume of hollow cylinder}=\pi R^2h-\pi r^2h[/tex]

where,

R = Radius of external cylinder,

r = Radius of internal cylinder.

h = Height of cylinder.

substituting our given values in above formula, we will get:

[tex]\text{Volume of hollow cylinder}=\pi (5\text{ in})^2(\text{23 in})-\pi (4\text{ in})^2(\text{23 in})\text{Volume of hollow cylinder}=\text{23 in}\cdot 3.14 ((5\text{ in})^2-(4\text{ in})^2)\text{Volume of hollow cylinder}=\text{23 in}\cdot 3.14 (25\text{ in}^2-16\text{ in}^2)\text{Volume of hollow cylinder}=\text{23 in}\cdot 3.14 (9\text{ in}^2)\text{Volume of hollow cylinder}=649.98\text{ in}^3[/tex]

Therefore, the volume of the pipe is 649.98 cubic inches.

Answer:

45

Step-by-step explanation

Juan has just completed a 15 kilometer race in 20 minutes.  What was his average speed in kilometers per hour?

Solution

First, 15 kilometers is a distance, so

       d  =  15

Next, we are given 20 minutes and we are asked to present the speed in kilometers per hour rather than kilometers per minute.  We need to convert 20 minutes to hours.  Since there are 60 minutes per hour, we divide by 60 to find out how many hours it took

t  =  20 minutes / 60 minutes per hour =  1/3 hours

Now we can use the d=rt equation:

15  =  (r)(1/3)

If we multiply both sides

(3)(5)  =  (r)(1/3)(3)  or  r  =  45

Juan's average speed was 45 kilometers per hour.

The answer is 75,300,000 hope this helps.

s = 3x - (1/2)y

Step-by-step explanation:

The perimeter of a square is 4s, where s is the side length.  Here,

12x - 2y = 4s, and so s = 3x - (1/2)y

b)there are no like terms to simplify this

Answer:

76[tex]\pi[/tex] or 238.76 [tex]units^{3}[/tex]

Step-by-step explanation:

The volume of a cylinder is V = [tex]\pi r^{2} h[/tex]

Here the radius is  r = [tex]\frac{1}{2} d[/tex] = [tex]\frac{1}{2}(4)=2[/tex]

The height is given as 19 ft

Then plug in all the numbers into the equation

V = [tex]\pi (2^{2})(19) = 76\pi = 238.76 units^{3}[/tex]

Answer:

Option 6

Step-by-step explanation:

To find the volume of a cone you use the formula 1/3*pi*r^2*h which would be pi*9^2*7. Then the volume of a cylinder is pi*9^2*50, so option 6 is right I believe.

Answer:

x= 20

Step-by-step explanation:

a flat angle is, in terms of geometry, the space between an intersection between two lines whose opening measures 180 degrees or 180º. Since the angle is 180º there is no difference between two lines or a line and we can say that the angles in a straight line always add up to 180º.

Step 1

define

according to the graph

3x+80+2x=flat angle=180°

3x+80+2x=180°

Step 2

solve for x

3x+80+2x=180°

5x+80=180

subtract 80 in each side

5x+80-80=180-80

5x=100

divide by 5

(5x)/5=100/5

x=20
