Answer:

39

Step-by-step explanation:

Answer:

39

Step-by-step explanation:

the answer is going up by the numbers 1,2,3,4...

you start with 4 and go up by 2

you then get 6 that's when you count up 3

you get 9 and then count up 4

which is 13 count up 5

18 count up 6

24 count up 7

31 count up 8

Answer:

[tex]134 \frac{6}{5}[/tex]

Step-by-step explanation:

The computation of the distance travelled is shown below:

Total distance would be

[tex]= 52 \frac{4}{ 5} + 14 \frac{ 4}{5}\\\\= \frac{264}{5} + \frac{74}{5}\\\\= \frac{338}{5}[/tex]

Now if the same route would taken again in order to back home

So, the total distance would be doubled

[tex]= \frac{338}{5} \times 2\\\\ = \frac{676}{5} \\\\= 134 \frac{6}{5}[/tex]

Answer:

I think the answer would be 'a'

Answer:

Step-by-step explanation:

[tex]y=-3(x^2+10x+25)-1\\ \\ y=-3x^2-30x-76\\ \\ dy=-6x-30\\ \\ d^2y=-6\\ \\ \text{Since the second derivative is always negative, when the first derivative is equal to zero the function will be at a global maximum.}\\ \\ dy=0=-6x-30\\ \\ x=-5\\ \\ f(-5)=-1\\ \\ \text{So the global maximum occurs at the point (-5,-1)[/tex]

Answer:

3,484 meters squared

Step-by-step explanation:

Since it’s a rectangle, opposite sides are the same length. This means 2 of the sides are 67 meters each, since the length of the rectangle is 67 meters. To find the width, add the 2 sides together that we know the length of (in this case it would be 67+67) and subtract it from the total perimeter (238-[67+67]). Take the result (104) and divide it by 2 (104÷2=52). Now that we know the width is 52 meters, you can find the area by multiplying the length times the width (67*52=3,484 meters)

Remember that the perimeter is the total length around the outside of the shape, and the area is the space inside of the shape

I’m not good at explaining things but I hope this helps!

Answer:

46

Step-by-step explanation:

110+6x=386

Answer: 46 times

Step-by-step explanation:

Since $110 is the constant and 6 is the coefficient because it is changing with each time he rents a tennis ball. The equation is 110+6t=386 where t in this case can represent (return groundstrokes)

110+6t=386 solve for t

6t=276

t=46

So he can return ground strokes 46 times

Answer:

[tex]y = \frac{-3}{4}[/tex]

Step-by-step explanation:

[tex]\frac{y}{2} + \frac{1}{4} = \frac{y}{6}[/tex]

Lets take all the variable terms in L.H.S & all the constant terms in R.H.S.

(While taking a term from one side to another side , it's sign changes )

⇒ [tex]\frac{y}{2} - \frac{y}{6} = -\frac{1}{4}[/tex]

Now in L.H.S. , lets solve the fractions and reduce its numerator and denominator .

⇒  [tex]\frac{3y - y}{6} = -\frac{1}{4}[/tex]

⇒  [tex]\frac{2y}{6} = -\frac{1}{4}[/tex]

⇒  [tex]\frac{y}{3} = -\frac{1}{4}[/tex]

Lets multiplying 3 on both the sides .

⇒  [tex]\frac{y}{3} \times 3 = -\frac{1}{4} \times 3[/tex]

⇒  [tex]y = \frac{-3}{4}[/tex]

Answer:

c.28

Step-by-step explanation:

Given

f(x) = 8x + 10 and g(x) = 6x - 4

f(4) = 8*4 + 10

    = 32 + 10

    = 42

g(3) = 6 * 3 - 4

      = 18 - 4

      = 14

Now

f(4) - g(3)

= 42 - 14

=28

hope it will help :)

Answer:

10 minutes

Step-by-step explanation:

This is somewhat of a trick question and also incomplete.

Assuming he walks his dog 1/6th of an hour each week, he walks his dog 10 minutes per week.

If this is incorrect please tell me the complete question

Answer:

y= 30 x=15

set up your proportions for example 9/6 to y/20 and 9/6 to x/10 and then cross multiply

Answer:

L= 90, M=53, K=37

Step-by-step explanation:

Tilt your phone/computer to the right, and you'll see the 90° angle for L. Now you're left with two more, and just compare which angle is bigger, K or M. M is bigger, so you apply the bigger number out of the you got which is 53. Now no doubts, K is 37.

Answer:

part A: the warmer the city temp was the more lemonade that was sold so a hotter day will sell more lemonade

part B: i used points 40,8 and 90,20 and got m= 25/6 then i did y=mx+b

90=25/6(1)+b

90/1=25/6+b

25/6   25/6

and then B= 21.6

Step-by-step explanation: im not sure if i did it right so i would check i havent done this since like the 6th grade like 4 years or so ago lol
