What is the value of the expression shown below? 7 + (10 - 4 )^2 divided 4 x (1/2)

Answers

i’m pretty sure 21.5 because you do what is in parentheses first which is 10-4=6, then you square to equal 36 then add 7=43 and divide by 2 bc 4(1/2) is 2 and you get 43/2 which is 21.5

Answer:

43 / 2  = 21  1/2 = 21.5

Step-by-step explanation:

7+(10-4)^2/ 4 (12)        you can either multiply by  4(1/2)/4(12) or do the following

Subtract 4 from 10 to get 6.

7+6^2 / 4×(  1/2)  

Calculate 6 to the power of 2 and get 36.

7+36 / 4×(  1/2  )  

Add 7 and 36 to get 43.

43 / 4× 1/2  

 Multiply 4 and    1/2   ​ to get 2.

43 / 2  = 21  1/2 = 21.5

4,6 would be the correct answer

(A) (4, 6)

Step-by-step explanation:

Since the 2nd stage light is above P, then its x-coordinate is also the same as that of P, which is 4. We know that there are 2 units per grid and since the 2nd stage is 8 units above P, the conversion to the number of grids is

[tex]8\:\text{units}×\dfrac{1\:\text{grid}}{2\:\text{units}} = 4\:\text{grids}[/tex]

So count 4 grids above the location of P, which is (4, -2) and you will get the coordinate (4, 6).

Fergus has 3 1/4 cups of oats

= 13/4 cups of oats

Oatmeal bars = 2 2/3

= 8/3 cups of oatmeal used

Therefore cups of oats left = 13/4 - 8/3

= 39/12 - 32/12

= 7/12 cups of oats left

She borrowed 1 cup of oats from neighbour

7/12 + 1/1

= 7/12 + 12/12

= 19/12 cups of oats

Blueberry oats muffin = 1 3/4 cups of oats

= 7/4 cups of oats

Total she will have now = 19/12-7/4

Why are the divisibility rules for 2, 3, and 5 very useful for determining prime and composite numbers

1. They are the smallest odd numbers
2. They add up to 10
3. They are prime numbers with nice divisibility rules
4. They multiply to 30
5. They can be multiplied together to make every number

Answers

Answer:

option 3.

Step-by-step explanation:

alright, ima explain each option.

1. "smallest odd numbers" 2 is an even number. that's out of the playing field.

2. "add up to 10" sure, they do add up to 10, but finding prime and composite numbers are all about division and multiplication.

3. this is true. 2, 3, and 5 are all prime numbers, and they have the nice divisibility rules. [ for 2, it has to be even, for 5, it has to end in 0 or 5, and 3 has to have the sum of its digits being divisible by 3. ]

4. they do multiply to 30, but this does not help break the composite numbers down.

5. we cannot make every number with just these. we can not multiply any other whole number to get 7 for per example, because it's a prime number.

My neighborhood is full of one-way streets. To drive from my house to the grocery store, I have to go 1 block south, then 1 block east, then 5 blocks north, then 2 blocks east. Each block is 1/16 of a mile. How much shorter would my trip be if I could fly like a bird (that is, travel in a straight line)?
I FOUND THE distance for non bird which is 9/16. I wanna apply the pythagoreum theorum and draw a straight line to make it a triangle so I can do so but don't know where to place it

Answers

1/4. . Hope this helps you
Let's suppose that your house is located at (0,0)

1 block south from here puts you at (0, -1/16)

1 block east from here now puts you at (1/16, -1/16)

5 blocks north from here puts you at (1/16, 4/16)

2 blocks east from here puts you at (3/16, 4/16)


You have traveled (1/16) ( 1 + 1 + 5 + 2) = 9 / 16 of a mile

The "straightline" distance between (0, 0) and (3/16, 4/16) =

sqrt [ (3/16^2 + (4/16)^2 ] = sqrt [ 25 / 256] = 5 /16 of a mile

Your trip would be [ 9/16 - 5/16 ] which equals 4/16 simplified equals 1/4 of a mile.

HELP PLEASE! Write an equation with variables on both sides that has a single solution "-1." Explain how to find that solution

Answers

ANSWER : HEY MATE

The solution to the equation 2x + 3 = x + 2, where x = -1, is found by isolating the variable "x" and simplifying the equation step by step

Let's create an equation with variables on both sides that has a single solution of "-1."

Let's call the variable "x."

An equation that meets these criteria is:

2x + 3 = x + 2.

We want to isolate the variable "x" on one side of the equation to find the solution.

Start by simplifying both sides of the equation.

On the left side, we have; 2x + 3;

And, on the right side, we have x + 2.

Now solve the equation as;

2x + 3 = x + 2

Subtract x on both sides;

2x - x + 3 = 2

x + 3 = 2

Subtract 3 on both sides;

x = 2 - 3

x = - 1

So, the solution to the equation 2x + 3 = x + 2, where x = -1, is found by isolating the variable "x" and simplifying the equation step by step.

Gina wants to solve the following proportion.

B. solve the proportion. show your work.

Answers

Step-by-step explanation:

please don't understand the question. will be happy if you take a shot of it.

Thanks

a/5/8 = 3/5 / 2/3

We can take the reciprocal of the denominator, since the denominator itself is a fraction

The above equation can be rephrased as,
(a) / (5/8) = (3/5) / (2/3)

Taking reciprocal

8a / 5 = 3*3 / 5*2

8a / 5 = 9 / 5*2

a = 9 * 5 / 5*2*8

5’s get canceled, 2 and 8 gets multiplied in the denominator.

We will then be left with,

a = 9 / 16
