Kelly runs a distance of 100 metres in a time of 10.52 seconds.
The distance of 100 metres was measured to the nearest metre.

The time of 10.52 seconds was measured to the nearest hundredth of a second.

(a) Write down the upper bound for the distance of 100 metres.

Answers

Answer 1

The upper bound means the highest number that you can round up to the nearest unit, in this case meters. So the upper bound for the distance of 100 meters is 100.4 meters.

Find the missing side of each triangle. Round your answers to the nearest tenth if necessary. (Please Show)

Answers

Answer:

x = 12.2 mi

Step-by-step explanation:

Given the two sides of the right triangle:

a = 6.1 mi

b = 10.6 mi

c = x

Use the Pythagorean Theorem to solve for the value of the hypotenuse, x:

c² = a² + b²

c² = (6.1)² + (10.6)²

[tex]\sqrt{(c^{2})} = \sqrt{37.21 + 112.36}[/tex]

c = 12.2 mi

Therefore, the value of the hypotenuse is:  x = 12.2 mi

>> Answer

___________

[tex] \: [/tex]

[tex]\boxed{ \rm{answer \: by \: { \boxed{ \rm{☆HayabusaBrainly}}}}}[/tex]

Step by step :

x² = (10,6)² + (6,1)²

x² = 112,36 + 37,21

x² = 149,57

x = 12,22mi

A special type of door lock has a panel with five buttons labeled with the digits 1 through 5. This lock is opened by a sequence of three actions. Each action consists of either pressing one of the buttons or pressing a pair of them simultaneously.

Answers

There are several ways the door can be locked, these ways illustrate combination.

There are 3375 possible combinations

From the question, we have:

[tex]\mathbf{n = 5}[/tex] --- the number of digits

[tex]\mathbf{r = 3}[/tex] ---- the number of actions

Each of the three actions can either be:

Pressing one buttonPressing a pair of buttons

The number of ways of pressing a button is:

[tex]\mathbf{n_1 = ^5C_1}[/tex]

Apply combination formula

[tex]\mathbf{n_1 = \frac{5!}{(5-1)!1!}}[/tex]

[tex]\mathbf{n_1 = \frac{5!}{4!1!}}[/tex]

[tex]\mathbf{n_1 = \frac{5 \times 4!}{4! \times 1}}[/tex]

[tex]\mathbf{n_1 = 5}[/tex]

The number of ways of pressing a pair is:

[tex]\mathbf{n_2 = ^5C_2}[/tex]

Apply combination formula

[tex]\mathbf{n_2 = \frac{5!}{(5-2)!2!}}[/tex]

[tex]\mathbf{n_2 = \frac{5!}{3!2!}}[/tex]

[tex]\mathbf{n_2 = \frac{5 \times 4 \times 3!}{3! \times 2 \times 1}}[/tex]

[tex]\mathbf{n_2 = 10}[/tex]

So, the number of ways of performing one action is:

[tex]\mathbf{n =n_1 + n_2}[/tex]

[tex]\mathbf{n =5 + 10}[/tex]

[tex]\mathbf{n =15}[/tex]

For the three actions, the number of ways is:

[tex]\mathbf{Action = n^3}[/tex]

[tex]\mathbf{Action = 15^3}[/tex]

[tex]\mathbf{Action = 3375}[/tex]

Hence, there are 3375 possible combinations

½x - 5 = -6

Which solution makes this equation true?


1. -12

2. -2

Answers

Answer: -2

Let’s try x = -12

1/2(-12) - 5 = -6

PEMDAS says to multiply first

1/2 x -12 = -6

So

-6 - 5 = -6

-6 - 5 = -11 not -6 so it’s not that

Now let’s do x = -2

1/2(-2) - 5 = -6

Again, you multiply first

1/2 x -2 = -1

-1 - 5 = -6 so it works

the area of the rectangle is 0.1 square meter

Area of rectangle is Length * width

Let's solve the equations
It's clear from the rectangle that the widths are equal.
So 2x-1=x+2
2x-x=2+1
X=3 cm

Let's find y from the heights
2y=3y-1
3y-2y=1
y=1cm

Let's apply the area formula
A= L*W
3*1
= 3 cm ^2

We know 1 meter =100 cm

So 3cm * 1m^2/(100cm )^2
Area in meter = 0.0003 meter^2


Explain why it does not matter which point you choose when writing the
equation of the line in point-slope form, given two points.

Answers

Answer:

because, it will completely change the slope

Step-by-step explanation:

It does not matter which point you choose when writing the

equation of the line in point-slope form because the slope of the line remains same.

What is a slope ?

A slope can be thought of as rate of change of y axis with respect to x axis.

We have been asked in this statement that why it doesn't matter that which point we choose when writing the equation in point slope form.

Let us understand this with an example,Suppose we have two pair of points. (x₁,y₁) = (2,3) and (x₂,y₂) = (5,9).

We know slope(m) is = (y₂-y₁)/(x₂-x₁).

Slope(m₁) = (9-3)/(5-2)

               = 6/3

               = 2.

Now if interchange the points  (x₁,y₁) =  (5,9) and  (x₂,y₂) =  (2,3).

Slope(m₂) = (3-9)/(2-5)

                = -6/-3

                = 2.

So, even when interchanging the points the slope m₁ = m₂ this is the reason why it doesn't matter which point we choose.

Tiffany is filling her daughter's pool with water from a hose. She can fill the pool at a rate of 1/10 gallons per second.

Create at least three equivalent ratios that are associated with the rate. Use a double number line to show your work.

Answers

At first I assumed you were asking for 3 different ratios equivalent to 1/10, which could be 2/20, 10/100, or 5/50. But it seems you are asking for ratios equivalent to 1/10 gallons to second. For this, you could change both the 'gallons' and the 'seconds' to get different unit with the same ratio. 1/10 gallon / second * 60 seconds / 1 minute gallons / minute 1/10 gallon / second * 1 gallon / 4 quarts = 1/40 quarts / second combining these two conversions we can do 1/10 gallon / second * 60 second / 1 minute * 1 gallon / 4 quarts = 3/2% 3D

Final answer: 1/10 gallons / second = 6 gallons / minute = 1/40% 3D quarts / second = 3/2 quarts / minute Hope I helped :)

The three equivalent ratios are 6/1 gallons/minute, 1/40 quarts/second and 360/1 gallons/hour.

What is the ratio?

The ratio is defined as the comparison of two quantities of the same units that indicates how much of one quantity is present in the other quantity.

Given that, Tiffany can fill the pool at a rate of 1/10 gallons per second.

Equivalent ratios are the ratios that are the same when we compare them.

We know that, 60 seconds =1 minute

1/10 × 60 = 6 gallons/minute

1 gallon = 4 quarts

1/10 = 1/10×4 = 1/40 quarts/second

1 hour =60 minute

So, 6 gallons/minute =6×60

= 360 gallons/hour

Here, 6 gallons/minute = 1/40 quarts/second = 360 gallons/hour

Therefore, the three equivalent ratios are 6/1 gallons/minute, 1/40 quarts/second and 360/1 gallons/hour.

Maria started her savings account with $105. she adds $10 to it each month, including the first month. Jana Rae started her account with $0 she adds $25 to it each month. after how many months will the girls have the same amount in their accounts? how much will they have?​

Answers

Answer:

After 7 months, the girls will have the same amount in their accounts. They will have 175.

Step-by-step explanation:

Maria:

Starts with $105

Adds $10 each month

Jana Rae:

Starts with $0

Adds $25 each month

Set up an equation for both Maria and Jana.

m will represent the number of months.

Maria: 105 + 10m

Jana: 0 + 25m

You can do guess and check.

Let’s say m is equal to 6.

Subsitute m with 6 for both equations and check if they both end up having the same answer.

Maria: 105 + 10(6) = 165

Jana: 0 + 25(6) = 150

Is 165 and 150 equivalent? No

Let’s try m = 7 and do that same thing.

Maria: 105 + 10(7) = 175

Jana: 0 + 25(7) = 175

Now is the answer equal? Yes

So therefore, after 7 months, the girls will have the same amount in their accounts. They will have 175.

The windmill was, in fact, Napoleon's own creation. Why, then, asked somebody, had he spoken so strongly against it? Here Squealer looked very sly. That, he said, was Comrade Napoleon's cunning. He had seemed to oppose the windmill, simply as a maneuver to get rid of Snowball, who was a dangerous character and a bad influence. Now that Snowball was out of the way, the plan could go forward without his interference. This, said Squealer, was something called tactics.
