degrees Fahrenheit?
A) 5°F 0°F - 2°F -9°F
B) 0°F - 9°F - 2°F 5°F
С) -2°F– 9°F0°F 5°F
D) -9°F -2°F 0°F 5°F

Answer:

The number line is shown below.

Step-by-step explanation:

We need to represent number that is less than 3 on a number line.

Let x be numbers.

So, [tex]x<3[/tex].

Now, we have a number which represents x<3. Here 3 is not included in the solution set, so there is an open circle on 3 and left side of 3 are in the solution set.

The number line is shown below.

Answer:

(1,1)

Step-by-step explanation:

M=(x1+x2 / 2 , y1+y2 / 2)

M=(-2+4 / 2 , 4+ -2 / 2)

M=(2 / 2 , 2 / 2)

M=(1,1)

Answer:

(400/100)*80 = 320

Step-by-step explanation:

400 = 100%, just divide by 100 and multiply by 80

Answer:

La nota que Víctor no recuerda es 5.2

Step-by-step explanation:

La media es el valor promedio de un conjunto de datos numéricos y es también llamada promedio o media aritmética.

Su cálculo se obtiene al sumar todos los datos disponibles y dividir el resultado por el número total de esos datos:

[tex]Promedio=\frac{x_{1} +x_{2} +x_{3}+...+x_{n} }{N}[/tex]

donde N el número total de observaciones.

En este caso:

[tex]Promedio=\frac{x_{1} +x_{2} +x_{3}+x_{4} }{4}[/tex]

Siendo:

y reemplazando:

[tex]5.5=\frac{6 +6 +4.8+x_{4} }{4}[/tex]

Se obtiene:

5.5*4=6+6+4.8 +x₄

22=6+6+4.8 +x₄

22-6-6-4.8=x₄

x₄=5.2

I think it is a sample space.

A sample space is, according to the dictionary,

"an experiment or random trial is the set of all possible outcomes or results of that experiment"

I'm sorry if I misunderstood.

Answer:

4. 7 hours   6. 8.57

Step-by-step explanation:

Step-by-step explanation:

Since, Carlos completes the work in 5 hours.

So, in one hour she will do [tex] =\frac{1}{5}[/tex] part

Since, Jenny completes the work in 9 hours.

So, in one hour she will do [tex] =\frac{1}{9}[/tex] part

(Carlos + Jenny)'s one hour work together

[tex] =\frac{1}{5}+\frac{1}{9}\\

= \frac{9+5}{5\times 9}\\

= \frac{14}{45}\\[/tex]

Total time taken by Carlos and Jenny together [tex] =\frac{45}{14}= 3\frac{3}{14} \: hours[/tex]

Answer:

Step-by-step explanation:

[tex]-50 = -5x - 3(5x + 15)\\\\-5x-3\left(5x+15\right)=-50\\\\\mathrm{Expand}\:-3\left(5x+15\right):\quad -15x-45\\-5x-15x-45=-50\\\\\mathrm{Add\:similar\:elements:}\:-5x-15x=-20x\\-20x-45=-50\\\\\mathrm{Add\:}45\mathrm{\:to\:both\:sides}\\-20x-45+45=-50+45\\\\Simplify\\-20x=-5\\\\\mathrm{Divide\:both\:sides\:by\:}-20\\\frac{-20x}{-20}=\frac{-5}{-20}\\\\Simplify\\x=\frac{1}{4}[/tex]

Answer:

[tex]x = \frac{1}{4}[/tex]

Step-by-step explanation:

[tex]-50 = -5x - 3(5x + 15)[/tex]

Use -3 to open the bracket

[tex]-3(5x +15)\\\\= -15x -45\\\\ -50 = -5x-15x -45[/tex]

Collect like terms

[tex]-50 +45 =-5x -15x[/tex]

Simplify

[tex]-5 = -20x[/tex]

Divide both sides of the equation by -20

[tex]\frac{-5}{-20} = \frac{-20x}{-20} \\\\1/4 =x\\\\x = \frac{1}{4}[/tex]

Answer:

C. y-1=2(x+2)

Step-by-step explanation:

A. y-7=2(x-6)-point slope form: y-y1=2(x-x1)-coordinate point: (x1,y1)=(6,7)

Now let's check that the other point works-just sub in the coordinates for the x and y variables.

y-7=2(x-6)\\-1-7=2(2-6)\\-8=2(-4)\\-8=-8

So answer choice A. goes through both points, so no.

B. y=2x-5-slope-intercept form, so just sub in both sets of coordinates separately to see if they each work.

y=2x-5\\7=2(6)-5\\7=12-5\\7=7\\equal

y=2x-5\\-1=2(2)-5\\-1=4-5\\-1=-1\\equal

Both work, so no.

C. y-1=2(x+2)-point slope form that gives us first coordinate set--(-2,1)

Except that the point is actually (2,-1) not (-2,1).  That means that answer choice C is not an equation of the line thaat goes through (6,7) and (2,-1), so yes.

D. Anyway, if we check D--y+1=2(x-2)--coordinate point given: (2,-1), which is correct, so no.

Answer:

75

Step-by-step explanation:

Let full marks be x

Then pass marks is 40% of x which is 0.4x

As per given, we have

22= 0.4x - 8

Solving for x

0.4x = 30

x = 30/0.4

x = 75

So full marks is 75

Answer:

B) -2t^2+3t+5

and

C) 4t-7

Answer: -25

Step-by-step explanation:

-9 - 16 = -25  

-9-16   is the same as -9 + -16  which gives you  -25

Unit walking rate in miles per hour = 5 2/3 / 2 2/3 = 17/3 / 8/3 = 17/3 x 3/8 = 17/8 = 2 1/8 miles per hour.

Unit walking rate in hours per mile = 1/ 17/8 = 8/17 hours per mile.

Answer:

[tex] \boxed{ \bold{ \huge{\boxed{ \sf{x = - 11}}}}}[/tex]

Step-by-step explanation:

[tex] \sf{5x + 23 = 2(x - 5)}[/tex]

Distribute 2 through the parentheses

⇒[tex] \sf{5x + 23 = 2x - 10}[/tex]

Move 2x to left hand side and change it's sign

⇒[tex] \sf{5x - 2x + 23 = - 10}[/tex]

Move 23 to right hand side and change it's sign

⇒[tex] \sf{5x - 2x = - 10 - 23}[/tex]

Collect like terms

⇒[tex] \sf{3x = - 10 - 23}[/tex]

Calculate

⇒[tex] \sf{3x = - 33}[/tex]

Divide both sides of the equation by 3

⇒[tex] \sf{ \frac{3x}{3} = \frac{ - 33}{3} }[/tex]

Calculate

⇒[tex] \sf{x = - 11}[/tex]

Answer:

x = 3

Step-by-step explanation:

Step 1: Simplify both sides of the equation.

−2x+25=x+16

Step 2: Subtract x from both sides.

−3x+25=16

Step 3: Subtract 25 from both sides.

−3x=−9

Step 4: Divide both sides by -3

x=3

Answer:

The length of the sides are 3 feet and 4 feet, respectively.

Step-by-step explanation:

Given the fact that triangle is a right triangle, it can be represented by Pythagorean Theorem:

[tex]r^{2} = x^{2}+y^{2}[/tex]

Where:

[tex]r[/tex] - Hypotenuse, measured in feet.

[tex]x[/tex], [tex]y[/tex] - Legs, measured in feet.

In addition, each leg can be determined as functions of hypotenuse:

[tex]x = r-2\,ft[/tex]

[tex]y = r-1\,ft[/tex]

Hence, the Pythagorean identity can be expanded and remaining variable may be solved:

[tex]r^{2} = (r-2\,ft)^{2}+(r-1\,ft)^{2}[/tex]

[tex]r^{2} = r^{2}-4\cdot r +4 + r^{2}-2\cdot r +1[/tex]

[tex]r^{2}-6\cdot r +5 =0[/tex]

[tex](r-5)\cdot (r-1) = 0[/tex]

[tex]r = 5\,ft\,\vee\,r = 1\,ft[/tex]

According to the definition of hypotenuse, it must be longer than any of legs. Hence, there is just one solution that is reasonable:

[tex]r = 5\,ft[/tex]

And length of the sides are, respectively:

[tex]x = 5\,ft-2\,ft[/tex]

[tex]x =3\,ft[/tex]

[tex]y = 5\,ft-1\,ft[/tex]

[tex]y = 4\,ft[/tex]

The length of the sides are 3 feet and 4 feet, respectively.
