Which expression is equivalent to 28+7?

Answer:

5/12

Step-by-step explanation:

No. of times coin landed head up / Total no. of flips

= 125 / 300

= 25*5 / 25*12

= 5 / 12

Answer:

16 / 81

Step-by-step explanation:

Between digits 0 ,1 , 2 , 3 , 4 , 5 , 6 , 7 , 8 , 9

Prob (prime number) = Prime numbers / Total numbers ; Prime numbers = 1,3,5,7. So, Prob = 4 / 9

Prob (composite number) = Composite numbers / Total numbers ; Composite numbers = 2, 4, 6 , 8.  So, Prob = 4 / 9

Prob (Prime & Composite) = 4 / 9 x 4 / 9 = 16 / 81

Answer:

[tex]2^2+3^2[/tex]

[tex]2^2=4[/tex]

[tex]3^2=9[/tex]

[tex]=4+9[/tex]

[tex]=13[/tex]

Answer:

2.796x10^10

Step-by-step explanation:

4.66x10^8 in one second

1 minute is equal to 60 seconds

Multiply 4.66x10^8 by 60

= 2.796x10^10

Answer:

571

Step-by-step explanation:

We solve using z score.

z = (x-μ)/σ, where

x is the raw score = ?

μ is the population mean = 480

σ is the population standard deviation = 70

z = 1.3

Hence,

= 1.3 = x - 480/70

Cross Mulitiply

1.3 × 70 = x - 480

91 = x - 480

x = 480 + 91

x = 571

Therefore, Marulla's raw score is 571

Answer: [tex]\$1450[/tex]

Step-by-step explanation:

Given

Landon earns a 10% commission on his total sales

Suppose his total sales is x to get a commission of $145 i.e.

[tex]\Rightarrow x\times 10\%=145\\\Rightarrow 0.1x=145\\\Rightarrow x=\$1450[/tex]

Therefore, the amount of total sales must be $1450

Answer:

3

Step-by-step explanation:

y = -3x^2 + 5x + 3

                          ↑ this is "the number at the end/constant," and according to the question the number at the end/constant is the y-intercept

Thus, the y-intercept is 3.

Answer:

32 Books

Step-by-step explanation:

You know that the bookshelf is 2 feet long, and you know the book is 3/4 inches thick. To start you have to get a common measurement in this case we will use inches. You already know that 1 foot is 12 inches so 2 feet will be 24 inches. Next all you do is divide the 24 inches by 3/4 inches. This will give you 32 which is the total amount of books that can fit on the bookshelf.

Answer:

D) 26 two-pointers and 15 three-pointers

Step-by-step explanation:

x= 2 pointers

y= 3 pointers

Make a system of equations:

x=41-y

2x+3y=97

Plug In:

2(41-y)+3y=97

82+y=97

y= 15 (three point shots)

Check:

15(3)=45

97-45=52

52/2=26

x=26 (2 point shots)

Answer:

y=-6/5x -8

Step-by-step explanation:

slope is the same as gradient(m) so find the c in the equation y=mx+c using the point (-5,-2) which gives u -8 then substitute values of m and c in that very equation

Answer:

[tex]y=-\frac{6}{5}x-8[/tex]

Step-by-step explanation:

Same process as the other two lol

y= -(6/5)x+b

solve for b by plugging in the required coordinates

-2= -(6/5)(-5)+b

-2= 6+b

-8=b

put it all together

Step-by-step explanation:

volume = [(15×11)+(½×15×8)] x 12

= (165+60) x 12

= 225×12

= 2,700 cm³

Answer:

31350cm^3

Step-by-step explanation:

1/2(5 x 9.5 x 11)

= 261.25

261.25 x 12

= 3135

3135 x 10 =  3135cm^3

Answer:

28 miles per gallon

560/20=28

Step-by-step explanation:

Plz give me brainliest

Number of miles a car travels are 28.

The division is the process of repetitive subtraction. It is the inverse of the multiplication operation. It is defined as the act of forming equal groups. While dividing numbers, we break down a larger number into smaller numbers such that the multiplication of those smaller numbers will be equal to the larger number taken.

Number of gallons of gas = 20

A car with 20 gallons of gas can drive 560 miles

Based on the given conditions,

= [tex]\frac{560}{20}[/tex]

= 28

Hence, number of miles are 28.

Answer:

D. 15 is correct.

I did the quiz.

Answer:

The true statements are:

B and D.

Step-by-step explanation:

First, a linear function can be written as:

y = a*x + b

Such that a is the slope, and b is the y-intercept.

If we know that the graph of the function passes through the points (x₁, y₁) and (x₂, y₂) then the slope is:

a = (y₂ - y₁)/(x₂ - x₁)

Here we have a function that passes through the points (6, 7) and (10, 13), then if this function is linear, the slope is:

a = (13 - 7)/(10 - 6) = 6/4 = 3/2

Then the function will be something like:

f(x) = (3/2)*x + b

Knowing that the function passes through (6, 7), this means that:

f(6) = 7

Then:

(3/2)*6 + b = 7

3*3 + b = 7

9 + b = 7

b = 7 - 9 = -2

The function, if linear, is:

f(x) = (3/2)*x  - 2

Now let's read the statements:

A)  If the graph also contains the point (4, 4) then the function must not be linear.

If the point is a solution of the equation, then the function is linear.

If the point is not a solution of the equation, then the function is not linear.

f(4) = 4 = (3/2)*4  - 2

        4 = 3*2 - 2

        4 = 6 - 2 = 4

Then (4, 4) is a solution, so if the graph also contains the point (4, 4) the function can be linear. Then the statement "A" is false.

Now let's do the same analysis for the other statements:

B)  If the graph also contains the point (12, 16) then the function must not be linear.

F(12) = 6 = (3/2)*12 - 2 = 3*6 - 2 = 18 - 2 = 16

           6 = 16

(12, 16) is not a solution, so if the graph contains this point, the function is not a linear function, the statement is true.

C) If the graph also contains the point (1, 2) then the function could be linear.

f(1) = 2 = (3/2)*1 - 2 = 3/2 - 2 = -1/2

The point (1, 2) is not a solution, so if the graph contains this point, then the function can't be linear, so the statement is false.

D) If the graph also contains the point (8, 10) then the function could be linear.

f(8) = 10 = (3/2)*8 - 2

        10 = 3*4 - 2 = 12 - 2

        10 = 10

The point (8, 10) is a solution of the linear equation, so if the graph contains this point, the function could be linear, so the statement is true.
