Determine which of the following are the solutions to the equation below. x2=13

A. +/13


B.+/26


C.26


D.13

Answer:

4/5 OR 0.8

Step-by-step explanation:

Divide the distance between them by 5,280. You should then get a decimal of 0.8. Not sure if you are looking for decimal or fraction, but 0.8 as a fraction is 4/5. So 4/5 of a mile is in between their two houses. Hope this helps :)

Answer:

4 crickets

Step-by-step explanation:

On the first day, the lizard ate 50% of the 10 crickets it was given. 50% of 10 is 5 (10 times 0.5), so five crickets remain. The next day, the lizard ate 20% of the 5 remaining crickets. 20% of 5 is 1 (5 times 0.2), and 5-1=4, so 4 crickets are left.

Answer:

422[tex]cm^2[/tex]

Step-by-step explanation:

1. Approach

This problem asks one to find the surface area of the given figure. This can be done by splitting the given figure into two similar figures. Then calculate the surface area of each of the similar figures. After doing so, subtract the covered surface areas, the contact point between the two simple figures is not a part of the surface area since it is covered by the other part of the figure. Remember to take away twice the area of this contact point, since it is present on both figures.

2.Find the surface area of the first figure

The surface area of a figure is the two-dimensional space around the figure. In essence, if one were to wrap the figure in paper, the surface area is the amount of paper one would need. Find the 2-dimensional area of each side, this can be done by multiplying all combinations of two dimensions together, adding the results, and then multiplying that value by (2).

(5) * (10) = (50)

(5) * (7) = (35)

(7) * (10) = (70)

Now add thee value together,

(50) + (35) + (70)

= (155)

Double the result,

(155) * (2) = (310)

3. Find the surface area of the other figure

Now repeat the process that was used to find the surface area of the other figure for this figure.

(8) * (4) = (32)

(4) * (3) = (12)

(8) * (3) = (24)

Add the results,

(32) + (12) + (24) = (68)

Double the value,

(68) * (2) = (136)

3. Now subtract the repeated side

Now that one has the value of both simple figures, add up the value and then subtract twice the value of the repeated side.

(310) + (136) = (446)

(446) - ((2)*(4)*(3))

= (446) - (24)

= (422)

Answer:

The bicyclist rides (64) miles in (4) hours.

Step-by-step explanation:

As you can see the 64 is on the Distance side, so that shows how far he or she travels.  Then you can see on the bottom of the graph it shows you time in hours. The point is at 4, so he or she travels 64 miles in 4 hours.

Hope this helped.

Answer:

{4, 13}

Step-by-step explanation:

Represent the integers by I and J.  Then I + J = -17 and I*J = 52.

Let's solve this system using substitution.  Solve the first equation for I as follows:  

I + J = -17 becomes I = -J - 17

Substitute -J -17 for   I   in the second equation:

(-J - 17)*J = 52

Performing the indicated multiplication, we get:

-J^2 - 17J - 52 = 0

Let's solve this using the quadratic formula.  The quadratic coefficients here are {-1, -17, -52}, and so the discriminant, b^2 - 4ac, is

(-17)^2 - 4(-1)(-52), or 289 - 208, or 81.  This result is positive, so we know that the quadratic equation has two real, unequal roots.  They are:

      17 ± √81         17 ± 9

J =  --------------- = ---------------

         2(-1)                  -2

Evaluating this last result, we get J = (17 + 9)/2, or J = 13, and

J = (17 - 9)/2 = 8/2, or J = 4

Answer:

It's the second option

The formula for Area is A= 1/2bh ( b stand for base & h for height)

So it should be A= 1/2 (5) ( 2 1/2)

Answer:

B.

Step-by-step explanation:

We know that (4 + x) is bigger than 6, so we have to find the answer that has more than 4.  Since A and B both have answers that are more than 4, those are our options.  But notice that A has one error, first lets define a closed circle and an open circle.  A closed circle can mean it is greater than or equal to, it can also mean that it is less than or equal to.  But an open circle means that it is either less than, or greater than.  And because the equation has an open circle ( which is this sign >) it means that the answer is option B.

Here is a better picture of what a close circle and open circle look like:

Answer:

8:05 pm (If you round to the nearest tenth place)

Step-by-step explanation:

basically, 4:00 pm and 5:10 pm have a 1 hour and 10 minute difference.

1 hour and 10 minutes divided by 65 miles is 1.6923076 or 1.7 minutes

1.7 minutes times 150 miles is 2 hours and 55 minuets

2 hours and 55 minutes plus 5:10pm is 8:05 pm

I'm so sorry if I'm wrong!

Answer: a) d(t) = [tex]\frac{13}{14}[/tex] (t - 70) + 65   b: 6:41 pm

duration of time passed:

5:10 pm - 4:00 pm = 70 mins

distance = 65 miles

you points to use to make an equation:

(0,0) and (70,65)  ---------------------> ( (0,0) is bc youre beginning the trip and you have no distance )

find the slope of your "future" equation

[tex]\frac{y_2-y_1}{x_2-x_1}[/tex] = [tex]\frac{65}{70}[/tex] = [tex]\frac{13}{14}[/tex] = m

now use point-slope form

y - 65 =  [tex]\frac{13}{14}[/tex] (x - 70)

y=  [tex]\frac{13}{14}[/tex] (x - 70) + 65

and since it wants it in terms of d and t,

d(t) = [tex]\frac{13}{14}[/tex] (t - 70) + 65

part b:

150 =  [tex]\frac{13}{14}[/tex] (t - 70) + 65

85 = [tex]\frac{13}{14}[/tex] (t - 70)

85 = [tex]\frac{13}{14}[/tex] t - 65

150 = [tex]\frac{13}{14}[/tex] t

2100 = 13t

161.54 = t

about 162 minutes

Thennnn:

162/60 = 2 hours and 41 mins

4:00 pm + 2 hours and 41 mins = 6:41 pm

Answer:

2(19[tex]x[/tex]x  -11)

        0R

38x - 22

Step-by-step explanation:

QESTION: 18x – 4(9 – 5x) + 14

Rearrange terms that whould be -: 18x – 4(-5x + 9) + 14

Disterbot the one in brakect and the nagative four: – 4(-5x + 9)

SLOVE:  – 4(-5x + 9) ^^ 4 x 5 = 20 and 4 x 9 = 36 ^^ PUT THE ALL TOGETHER.

What you have now --> 18x + 20x - 36 + 14

Now, it's time to use your PEMDAS, we have Add and Subtract so you are going to do A fisrt (Add).

-36 + 14 = -22

Now you have, 18x + 20x - 22

Combine the like terms: 18x + 20x = 38x (don't forget the - 22)

38x - 22

2 x 19 = 38

2 x 11 = 22

What do you notice? ------- They all have 2 right? YES!, So put 2 in the front with parentheses, then put 19x and -11 in the parentheses.
