slope of the lines (-4,-1) and (-5,2)

Answer:

Alice : Belles : Chloe

  5   :       1      :   10

Step-by-step explanation:

If we represent Belles score as x, we can tell the following.

Alice's score will be 5x since her score is 5 times Belles score     (5)(x)

Chloe's score is 10x since her score is 2 times Alice's score         (2)(5x)

Now we can see the following ratio.....

Alice : Belles : Chloe

 5x   :    x      :  10x

(get rid of the x and the get)

Alice : Belles : Chloe

  5   :       1      :   10

The ratio of Alice's score to Belle's score to Chole's score is 1 : 5 : 10.

The relationship between two numbers which shows how much bigger one quantity is than another.

According to the given question

Alice's score was five times Belle's score.

Chloe's score was two times Alice's score.

Let Belle's score be x.

Therefore,

Alice's score = 5x

Chloe's score = 2×5x = 10x

So,

ratio of Alice's score to Belle's score to Chole's score = x : 5x : 10x

⇒Alice's score: Belles's Score: Chole's score = 1 : 5 : 10

Answer:

54.4 ml

Step-by-step explanation:

14.4% of 378 ml =

= 0.144 * 378 ml

= 54.432 ml

Answer: 54.4 ml

We will use substitution to solve the system. Step 1 is partially complete.

[tex]y = -2x - 9\\6x - 5y = -19\\\\6x - 5(-2x - 9) = -19\\\\6x + 10x + 45 = -19\\\\16x + 45 = -19\\\\16x = -64\\\\x = -4[/tex]

We will now use what we got for x to solve for y in one of the original equations.

[tex]6(-4) - 5y = -19\\\\-24 - 5y = -19\\\\-5y = 5\\\\y = -1[/tex]

The solution is (-4, -1).

Given:

A grid with a shaded region.

To find:

The probability that a point chosen at random on the grid will lie in the shaded region.

Solution:

We have,

Total number of small boxes = 100

Number of blue boxes (shaded region) = 36

Now,

probability that a point chosen at random on the grid will lie in the shaded region is

[tex]\text{Probability}=\dfrac{\text{Number of blue boxes (shaded region)}}{\text{Total number of small boxes}}[/tex]

[tex]\text{Probability}=\dfrac{36}{100}[/tex]

To find the probability in percent, multiply it by 100.

[tex]\text{Probability}\%=\dfrac{36}{100}\times 100[/tex]

[tex]\text{Probability}\%=36\%[/tex]

Therefore, the correct option is A.

Domain: 6 </= x < 11

Step-by-step explanation:

Domain refers to the set of possible input values, therefore the domain of a graph consists of all the input values shown on the x-axis.

Remember (this is very important!) :

Closed circles means including that number whereas open circles means not including that number

Domain: 6 </= x < 11

Note: </= means "less than or equal to"

Aops Question

Answer:

120°

Step-by-step explanation:

From the above question, the polygon is and hexagon, this means it has 6 sides.

Hence: Sums of the interior angles of a polygon = Sum = (n-2) × 180°

n = 6

Hence,

Sum of the interior angles = (6 - 2) × 180°

= 4 × 180°

= 720°

Hence:

The measure of an interior angle of a hexagon =

= Sum of the interior angles/Number of sides of the polygon

= 720°/6

= 120°

Answer:

120

I have no clue as to what the options were, but the answer is 61 and three-fifths.

Step-by-step explanation:

Well, the fraction options were a little distorted, so I'll work it out anyway.

7 • 8 4/5

7(8 + 4/5)

7 • 8 is 56, and 7 • 4/5 is 28/5.

56 + 28/5

28/5 as a mixed-number fraction (I think that's what it's called) is 5 3/5.

56 + 5 + 3/5

61 + 3/5

61 3/5 (61 and three-fifths)

There!

(Sorry about not getting the options...)

Answer:

A: 56+ 28/5 = 56 + 5 3/5 = 61 3/5

Answer:

5/7

Step-by-step explanation:

You are adding both fractions together to determine the total of the floor they both cleaned in all.

so 2/7 + 3/7 =    

To add fractions, you need both denominators to be the same. In this case, they are already the same so you don't need to adjust the fraction before adding them.

Now all you need to do is to add the numerators together so

2 + 3 = 5

So you put the numerator total over the common denominator.

* You do not add the denominators, only the numerators.

An equation that models the total cost (C), in dollars, of a taxi cab ride, where m is the number of miles driven is,

C = 0.75 m + 8

The correct option is C.

Two algebraic expressions having the same value and symbol '=' in between are called an equation.

Given:

A taxi cab company charges $8.00 per ride plus $0.75 for each mile driven.

An equation that models the total cost (C), in dollars, of a taxi cab ride, where m is the number of miles driven is,

C = 0.75m + 8

Therefore, C = 0.75m + 8.

Answer:

y=75

Step-by-step explanation:

Alright first off you want to be able to find the ratio to this to be able to find that Y you are looking for.

If you simplify y=45 and x=3 both by 3 you will get:

y=15 and x=1

now, lets turn that X to a 5 just like the other x which equals 5 as well...

but here's the catch when you times our X by 5 to equal 5 we are also going to times our Y by 5 to and do you know what 15 times 5 is it's 75.

now that we know that let's type that out to make it clear:

x=5 and y=75

you see the pattern now ;)

Use the formula,

I = Prt

P = Principal amount = 400

I  = interest = 18

r = annual rate

t = time in years = 9/12 = 3/4

so,

18 = 400*r*3/4

r =  0.06

so the annual interest rate is 0.06 or 6%.
