Simplify the expression

Answers

Answer:

9/4

Step-by-step explanation:

5×|-2-7(3)|-2×17

5×|-2-21|-34

5×|-23|-34

5×23-34

115-34=81

22+sq rt(7×28) 28=4×7 sq rt= 2×2×7×7

22+2×7=22+14=36

81÷9/36÷9=9/4

So the answer is a, now let me tell you why if you need proof

Starting from the top
So take the seven and multiply it to the 3 to get 21 and then subtract the negative two to the negative twenty one so you should have 5 | -23| -2*17 simply the |-23| so it says it’s absolute value which is 23 so you have 5*23 - 2*17, now just go ahead and multiply the 5 and the 23 to get 115 and the 2 to the 17 to get 34, now you should have 115-34, that’s obviously 81
Now for the bottom
22 + √7*28, now you just multiply the 7 to the 28 and you get 196 and the square root of that would be 14 so now you should have 81/22+14 so far, now just add the 22 and 14 to get 36 and simplify the fraction to get 9/4 and that’s A
(if you keep going, you get 2.25)

A square with an area of 250sq.m is inscribed in a circle. Find the diameter of the circle

Answers

Answer:

Area of square = 250 sq m

[tex]Side \: of \: square = \sqrt{250} \: m \\ diagonal \: of \: square \\ = \sqrt{ {( \sqrt{250)} }^{2} + {( \sqrt{250)} }^{2}} \\ = \sqrt{250 + 250 } \\ = \sqrt{500} \: m \\ = 22.3606798 \: m \\ = 22.36 \: m \\ \therefore \: diameter \: of \: circle = 22.36 \: m[/tex]

jordan has 3/8 pond of candy. he gave some to his brother and now he has 1/10 pound left.how much did he give to his brother

Answers

Given :

Amount of candy Jordan have , [tex]A=\dfrac{3}{8}\ pounds[/tex] .

Amount left after giving some to brother , [tex]a=\dfrac{1}{10}\ pounds[/tex] .

To Find :

How much did he give to his brother .

Solution :

Let , amount he gave to his brother is , b .

So ,

[tex]\text{Amount left = Total amount -Amount he give to his brother}\\\\a=A-b\\\\b=A-a\\\\b=\dfrac{3}{8}-\dfrac{1}{10}\\\\b=\dfrac{(3\times 10)-8}{80}\\\\b=\dfrac{22}{80}\\\\b=\dfrac{11}{40}[/tex]

So , amount he give to his brother is  [tex]\dfrac{11}{40}[/tex] .

Hence , this is the required solution .

Step-by-step explanation:

Zeke claims that the function to the left should have three shaded regions for its range because it is a three-piece piecewise function. Is Zeke correct? Yes or No

Answers

Answer:

No

Step-by-step explanation:

The input to a function which is the domain of the function is the x-variable or independent variable, while the output of a function which is the range of the function is the y-variable or dependent variable

In the given function, the outputs or the ranges of the function for the input of piece with x-values -3 ≤ x ≤ -8 completely overlaps the ranges for the piece with x-values 1 < x ≤ 3, therefore, both ranges can be represented by a single shaded region, giving a total of two shaded regions.

The function on the left of the graph should have two shaded regions for its range because the range of the two functions overlaps. Therefore, no the claim of Zeke is incorrect.

Given :

The graph shows the piece-wise function.

The following steps can be used to determine that the Zeke claims is correct or not:

Step 1 - The domain of the graph of the function present in the third and fourth quadrant is:      

[tex]-8\leq x \leq -3[/tex]

Step 2 - The domain of the graph of the function present in the second quadrant is:

[tex]-2< x < -1[/tex]

Step 3 - The domain of the graph of the function present in the first quadrant is:

[tex]1< x\leq 3[/tex]

The function on the left of the graph should have two shaded regions for its range because the range of the two functions overlaps. Therefore, no the claim of Zeke is incorrect.

Step-by-step explanation:

it's actually easy : just do 50÷4 but then u will get something like 12.5 so if you are confused , you can divide by the closest number to 50 and the number which is a multiple of 4

so,

48÷4 = 12 and with the remaining 2 $ she can buy a half flip flop more if she wants because 4/2

Therefore , the total number of flip flops she can buy = 12½ flip flops
