Answer:

8.02 × 10-³

Step-by-step explanation:

Jeff modeled the number of minutes that he read each day during the first week of the summer. The recursive function, f(x), can be used to determine the number of minutes that he had read after a certain number of days, where x represents the number of days. f(1) = 28 f(x) = f(x - 1) + 8 Use the recursive function to find the number of minutes that Jeff read after 3 days of summer.

Answers

9514 1404 393

Answer:

44 minutes

Step-by-step explanation:

We are given f(1) = 28.

Using the recursive formula ...

f(2) = f(1) +8 = 28 +8 = 36

f(3) = f(2) +8 = 36 +8 = 44

Jeff read 44 minutes after 3 days of summer.

to compound 50% solution in which proportion must 95% sol and 30% sol be mixed to make
500 ml

Answers

Answer:

4/9

Step-by-step explanation:

Let the amount of 95% sol = a ml and

the amount of 30% sol = b ml.

So, the total amount of the compound=a+b=500 ml

As the compound is 50% solution, so

95% of a + 30% of b= 50% of (a+b)

(95/100)a+(30/100)b=(50/100)(a+b) [from equation (i)]

95a + 30b = 50(a+b)

95(a/b)+30 = 50(a+b)/b [dividing both sides by b]

95(a/b)+30 = 50(a/b+1)

95(a/b)+30 = 50(a/b)+50

95(a/b)-50(a/b)=50-30

45(a/b)=20

a/b=20/45

a/b=4/9

Therefore, a:b=4:9

As a+b= 500 ml, so the amount of 95% sol = [tex]\frac {500}{13}\times 4=\frac{2000}{13}=153.85[/tex] ml

and the amount of 95% sol = [tex]\frac {500}{13}\times 9=\frac{4500}{13}=346.15[/tex] ml

Hence, the proportion of 95% sol and 30% sol to make a compound of 50% sol must be 4/9.

What is 9 times 9
It’s so hard

Answers

9x9 is 81 and yes its very hard haha

If you’re having trouble with your nines times table use the finger trick. But it only works for 9x1-9-10 so hold up your hands in front of you and your palms facing towards you. Since you’re using 9x9 put your ninth finger down and the amount of fingers on your left would be the amount of tens so their would be 8 tens meaning 80 and the amount of fingers on the right side of the finger that is down would be the ones so there is one finger on the right. After that, you can just add them up. 80+1= 81 if you need another example just comment on this and say if you’re confused.:)

Kendra has an unlimited supply of unbreakable sticks of length 2, 4 and 6 inches. Using these sticks, how many non-congruent triangles can she make if each side is made with a whole stick

Answers

Answer:

Unlimited number of triangles.

Step-by-step explanation:

Unlimited number of triangles can be made because Kendra has unlimited supply of unbreakable sticks. If she has limited number of sticks suppose 90 sticks so she can be able to made 30 non-congruent triangles from these number of sticks so if the number is not known so we are unable to say about the number of triangles should be made from unlimited unbreakable sticks.

The sum of three consecutive even numbers is 228. What is the 3rd number?

Answers

Answer:

74 , 76 , 78

Step-by-step explanation:

Let the first of your number be x, As you are only looking at even integers, the next consecutive even integer would be x+2 and the consecutive even integer after that would be x+4. The sum of these three even integers results in 228 so we can say that:

[tex]First\ even\ number\ + Second\ even\ number\ + Third\ even\ number\ =228 \\\\x+(x+2)+(x+4)=228[/tex]

[tex]x+x+2+x+4=228\\3x+6=228\\3x=228-6\\3x=222\\x=222/3\\x=74\\[/tex]

so the first even number is 74 then the second consecutive even number is 76 then the third consecutive even number is 78
