Answer:
60%
Step-by-step explanation:
You see how many answers she got got right and to do that you subtract 170-68 and get 102. That's how many she answered correctly. Then you need to find the percentage and to do that you divide 102 by 170 which gives you 0.6, which can be read as 60%. Hope that helps! :)

We can put this as:
√3.6 < r < √3.7, where r is the real number√360/10 < r < √370/10361 = 19² is in the interval:
360 < 361 < 370So,
√360/10 < √361/10 < √370/10√3.6 < 1.9 < √3.7r = 1.9 is the number17+{11-[15-(4+8-3-2)]+1} dau coroana

what is the equalivent decimal for 17/20
Answer:
0.85
Step-by-step explanation:
20•5=100
17•5=x
7•5=35
10•5=50
35+50=85
then put the decimal 2 spots to the left and you will get 0.85 or 85%
Hey there!
• In order to convert a fraction into a decimal you divide the numerator (the number at the TOP) from the denominator (the number at the BOTTOM)
17/20
= 17 ÷ 20
= 0.85
= 85%
The decimal that is equivalent to 17/20 is: 0.85
Answer: 0.85
Good luck on your assignment and enjoy your day!

For what value(s) of k will the relation not be a function? S={(2-|k+1|,4), (-6,7)}
A relation is the relationship between variables. When each input has one output, the relation is a function. When the value of k is 5 or 3, the relation will not be a function.
Given that:
[tex]S= \{(2-|k+1|,4), (-6,7)\}[/tex]
For S, not to be a function, 1 domain element must point to more than one range elements.
This means that:
[tex]2-|k+1| = 6[/tex]
Collect like terms
[tex]-|k+1| = 6 - 2[/tex]
[tex]-|k+1| = 4[/tex]
Multiply by -1
[tex]|k+1| = -4[/tex]
Remove absolute bracket
[tex]k+1 = -4\ or\ k+1 = 4[/tex]
Solve for k
[tex]k =-1 -4\ or\ k= -1+4[/tex]
[tex]k =-5\ or\ k= 3[/tex]
Hence, when k is 5 or 3, the relation will not be a function.

296 divide by 0.08 whats the answer plz answer, and show me how you did it plz
Answer:
Step-by-step explanation:
Ok so u can’t divide a decimal with a whole number so u have to move the decimal poin from the 8 twice so it’s on the other side of the 8 and then there shouldn’t be any zeros before the 8 now divide 296 by 8 and instead of leaving the whole number like that u have to add the decimal point to it. So it should look like this 296.00 and then u can divide which is 3,700 hope this helped <3
|x-3|<2
|4x+1|>0
|x-1|<5
Ayudaaaaaaa pleaseeeee
Recuerda que
• |x| = x si x ≥ 0
• |x| = -x si x < 0
Necesitas considerar dos casos:
• si x - 3 ≥ 0,
|x - 3| < 1 ⇒ x - 3 < 1 ⇒ x < 4
• si x - 3 < 0,
|x - 3| < 1 ⇒ -(x - 3) = 3 - x < 1 ⇒ -x < -2 ⇒ x > 2
Entonces la solución consta de todos los números reales x tales que x > 2 y x < 4, o simplemente 2 < x < 4.
El método para resolver las otras desigualdades es el mismo.
|4x + 1| > 0 ⇒ 4x + 1 > 0 o -(4x + 1) > 0
… ⇒ 4x + 1 > 0 o -4x - 1 > 0
… ⇒ 4x > -1 o -4x > 1
… ⇒ x > -1/4 o x < -1/4
⇒ x ≠ -1/4
|x - 1| < 5 ⇒ x - 1 < 5 o -(x - 1) < 5
… ⇒ x - 1 < 5 o -x + 1 < 5
… ⇒ x < 6 o -x < 4
… ⇒ x < 6 o x > -4
⇒ -4 < x < 6

Answer:
y = -5/4 - 31/5
Step-by-step explanation:
A: (-1,-7) and B: (9,1)
Slope: (-7-1)/(-1-9) = -8/-10 = 4/5
Slope: 4/5. Point (9,1)
y-1 = 4/5 (x-9)
y-1 = 4/5x - 36/5
y = 4/5x - 36/5 + 1
y = 4/5x - 31/5
Perpendicular bisector = Y = - 5/4x - 31/5

2) Jessica went to the mall. She paid $14.57 on shorts and $10.20 on pants
with two $20 bills. She went to 2 shops. How much money did Jessica get in change?
Answer:
15.23
Step-by-step explanation:
First, you add 14.57 with 10.20 which equals 24.77.
then you minus 24.77 from 40 which equals 15.23!
hope this helps you :D
Hello :D
To do this you need to do:
$20 x 2 = $40.00
$14.57 + $10.20 = $24.77
$40.00 - $24.77 = $15.23
The answer is $15.23. I hope this helps :)
