solve for all real numbers of x. x^2+4=0

Step-by-step explanation:

You start with milk : water = 7 :3

Total volume = 800 mL

Volume of milk = 7/10*800 = 560 mL

Volume of water = 3/10*800 = 240 mL water

Volume of milk must remain constant at 560 mL which is 2 parts

Therefore 3 parts water = 3/2*560 = 840 mL water final volume

You need to add 840 mL - 240 mL = 600 mL water .

Hope it helps

The number of 5ths that equals 9 is gotten bus using multiplication property of equality by multiplying 9 by 5 to give; 45

We want to find the number of 5ths that equals 9. We can express this as;

¹/₅x = 9

Where x is the number that is multiplied with one - fifth to equal 9.

To solve it, we will apply multiplication property of equality by multiplying both sides by 5 to get;

x = 45

Thus, the number of 5ths that equals 9 is 45.

Answer:

(-5)^3 = -125

Step-by-step explanation:

(-5)^3

= (-5) × (-5) × (-5) = -125

= (-5)^3 = -125

(-5) to the power of 3 is just (-5) multiplied by itself 3 times so (-5) to the power of 3 is (-5)^3 which is -125

Step-by-step explanation:

it's quite easy to go around this problem.

first you gotta consider the negative (-) sign..

you know when a negative sign multiplies another negative sign you'll get a positive sign.

example

-5*-5= ?

since you know the negative sign would turn to a positive sign when they multiply each other.

and be mindful of problems with different signs like

−6×9, you'll definitely get a negative answer

Now to your question.

(−5)^3, if you're struggling with composite expression,all you need is to break it down to simplified form

since it's -5 raised to the power of 3

you can as well write it as -5*-5*-5 (pay attention to the negative sign). then go through with your calculations

if you do it correctly, you'll arrive at the answer

-125

Answer:

m = -1

Step-by-step explanation:

3(m + 2) = -( 6- m) + 10​

Distribute

3m +6 = -6+m +10

Combine like terms

3m+6  = m+4

Subtract m from each side

3m-m+6 = m+4-m

2m+6 = 4

Subtract 6 from each side

2m+6-6 = 4-6

2m = -2

Divide by 2

2m/2 = -2/2

m = -1

430m+142m=h

The original height of the helicopter would be 142m higher than what it just descendet to.

Answer oor the question

12x+20y

sup

210 - 210 x 16% = 210 x 84% = 176,40

so x^2-10=0

we add 10 to both sides of the equation  x^2 = 10

then take the square root of both sides of the equation to eliminate the exponent on the left side  x = ± √10

The complete solution is the result of both the positive and negative portions of the solution. x = √10 ,−√10

the result can be shown in multiple forms

Exact Form :x=√10,−√10x=10,-10

Decimal Form: x=3.16227766…,−3.16227766

Answer:

let [tex]x[/tex] = height of rectangle

Given:

Therefore,

Shaded area = area of rectangle - area of circle

Area of rectangle = length × height

                             = [tex]3x \times x[/tex]

                             = [tex]3x^2[/tex]

Area of circle = [tex]\pi r^2[/tex]

                       [tex]=\pi \left(\dfrac{1}{2}x\right)^2[/tex]

                       [tex]=\dfrac14\pi x^2[/tex]

[tex]\implies \textsf{shaded area}=3x^2-\dfrac14\pi x^2[/tex]

If the radius = 2 cm, then the diameter ([tex]x[/tex]) = 4 cm

Substituting [tex]x = 4[/tex] into the equation:

[tex]\implies \textsf{shaded area}=3(4)^2-\dfrac14\pi (4)^2[/tex]

[tex]\implies \textsf{shaded area}=48-4\pi[/tex]

[tex]\implies \textsf{shaded area}=4(12-\pi) \textsf{ cm}^2[/tex]

Answer:

Step-by-step explanation:

Goal: For each spot you need to find the value associated with the column name.

Radius: half the maximum width of a circle

Height: The measure of how tall the cylinder is

Base Area: Can be found using the equation BA = π*r²

To find volume in terms of pi:

Only square the radius. Do not multiply the r² value by π. After squaring the radius, multiply it by the height of the cylinder.

Equation for Volume of a Cylinder = h*BA = h*π*r² =Volume

This can also be done in reverse if you know the volume and either the Base Area, the radius, or the height.

Simply do:

[tex]\sqrt{ \frac{V}{h*pi}} =r[/tex]

to find the radius

OR

[tex]\sqrt{ \frac{V}{BA}} =h[/tex]

to find the height

OR

[tex]\frac{V}{h} =BA[/tex]

to find the Base Area

Answer:B At least 4 pounds but less than 6 pounds.

Step-by-step explanation:

Using histogram Option: D more than 4lbs but less than 6lbs is correct.

Histogram is virtual way to "display frequency data using bars and graphical representation of grouped frequencies".

According to the question,

A researcher weighed cantaloupes grown across a certain region the weight of cantaloupes and frequency is given in the histogram.

In order to find the third bin representation see the histogram's third bar it shows weight of the cantaloupes at least 4lbs but less than 6lbs.

Hence, Option: D more than 4lbs but less than 6lbs is correct.
