Answer:

-16°C

Step-by-step explanation:

The lov temperatures for a week are :

-15°C, -12 , -10°C, -12°C, -18°C, -20°C, and -25°C.

We need to find the mean love temperature for the week.

Total no. of observations = 7

Mean = sum of observations/total no of observations

[tex]M=-\dfrac{15+12+10+12+18+20+25}{7}\\\\M=-16^{\circ} C[/tex]

So, the mean temperature is -16°C.

Answer:

x - 7

Step-by-step explanation:

Given

[tex]\frac{x^2-49}{x+7}[/tex]

x² - 49 is a difference of squares and factors as (x - 7)(x + 7)

= [tex]\frac{(x-7)(x+7)}{x+7}[/tex] ← cancel x + 7 on the numerator/ denominator

= x - 7

Answer:

Formula used: a²-b²=(a-b)(a+b)

[tex] ★\:\:\frac{( {x}^{2} - 49) }{(x + 7)} = \frac{ ({x}^{2} - {7}^{2} ) }{(x + 7)} = \frac{(x - 7)(x + 7)}{(x + 7)} =\boxed{ (x - 7)}[/tex]

Answer:28

Step-by-step explanation:

This is a missing whole problem so you must divide 7 by 25/100

Or multiply it by it's reciprocal 100/25 or 4/1 x 7 = 28

Answer:

Negative

by multiplying that by 2, 6:3/8

Answer:

[tex]4\sqrt{2} =5.66[/tex]

Step-by-step explanation:

The square is in the circle, so the diameter is the diagonal line of the square. This divides the square into two right triangles.

Two sides of the right triangle equal 8. This qualifies it as a special right triangle. This triangle has two sides that = x (in this case 8) and the hypotenuse is [tex]x\sqrt{2}[/tex].

Substitute 8 in for x.

[tex]8\sqrt{2}[/tex] is the diameter, so we divide in half to get the radius = [tex]4\sqrt{2}[/tex]

plz mark the brainliest. if that is adding not multiplying, you will do 3 divide by 8 first and then add 12. I think its a typo and it is multiply so if it is multiply, it is B. plz mark the brainliest

Answer:

108

Step-by-step explanation:

Since B=3, you need to do 4(3)^2*3

Do 3^2, which is 9,

4*9=36,

36*3=108

Answer:

D) 18

Step-by-step explanation:

(9√2)²+(9√2)²=h²

81x2+81x2=h²

162+162=h²

324=h²

√324=h

18=h

angleD=(7b+1)angle E=(2b+1)and angle F=(b+8)

Answer:

<E = 35

Step-by-step explanation:

7b + 1 + 2b + 1 + b + 8 = 180

combine like terms

7 + 2 + 1 = 10

10b

1 + 1 + 8 = 10

10b + 10 = 180

substract 10 from 180

= 170

10b = 170

170 divided by 10

= 17

now plug in for b for angle E

2 (17) + 1

= 35

Answer:

The linear equation is Y=5x+8 where x>0

(you can input this into the Desmos graphing calculator to see the graph if you like!)

Step-by-step explanation:

To get the answer is fairly straight forward. If we know that distance covered is x in the equation and we know that a linear equation follows the template Y=mX+b where m is slope and b is the y-intercept. The first step is to fill in what we know. That would look as such Y=_X+_. We can then attempt to fill in the blanks for m and b. Because we know that it is 5 rupees extra per subsequent kilometre we can put 5 as the multiplier for x and there is our m or slope. We now have Y=5x+_. Now for b. B in this case is quite simple as is showing us where the start of the graph is. It is stated that there is a flat fee of 8 rupees, so the total can never be less than 8. Because b is simply where the line intercepts the y axis, and we want it to intercept at 8, we can just put a plus 8. And there you have it Y=5x+8. One important note is that the graph when drawn should be a ray extending from point (0,8). This is because we want to eliminate all of the areas on the plane that would make the fare negative, as we could not have a negative cab fare. This is as simple as plotting the line starting from point (0,8) on the y axis. Happy to help!  

Answer:

The radius of the sphere will be:

Step-by-step explanation:

Given that a sphere has the same volume as a cube with edge length 5.

[tex]V_c=V_s[/tex]

[tex]\:a^3=\frac{4}{3}\pi r^3[/tex]

[tex]\:r^3=\frac{3\:a^3}{4\pi }[/tex]

[tex]\:\:r=\sqrt[3]{\frac{3\:a^3}{4\pi \:}\:\:}[/tex]

substitute a = 5

[tex]r=\sqrt[3]{\frac{3\:\left(5\right)^3}{4\pi \:\:\:}\:\:}[/tex]

[tex]r=3.1[/tex] units

Therefore, the radius of the sphere will be:

The best unit for measuring distance of Micah apartment from school is kilometers.

Here,

It takes 20 minutes to drive from Micah's apartment to his school.

We have to find the best unit to measuring the distance between Micah's apartment from school.

What is Units in distance?

The most common units of distance are millimeters, centimeters, meters, and kilometers.

Now,

It drive and takes 20 minutes to reach Micha's school from his apartment.

That's mean distance between Micha's school from his apartment is too long.

Hence, we measure the distance from Micah's apartment to his school

in Kilometers.

Because, Meters, centimeter, millimeter all are smaller than kilometer.

So,

The best unit for measuring distance of Micah lives from school is kilometers.

Answer:

2. y= -2x

Step-by-step explanation:

When the line is on an exact point like it is on (-4, 8), we can simplify it by going rise/run

Rise is the same as y (8), and your run is x (-4)

When you divide 8/-4, your answer will be -2

Therefore, the answer is y= -2x
