someone answer this please

Answer:

2 hours and 45 minutes

Step-by-step explanation:

This problem can take a while if you cannot observer the answer quickly.

First of all we can see that 32=2*2*2*2*2=2^5

243, if you don't know its actually is 3^5

Now we can see that this turns into...

- 2^5/3^5

since the 5th power doesn't change the sign of the original number, we can put the negative in the ( ), if you don't know what I mean look below

(-3)^2=9 Positive

(-3)^3=-27 Negative since its to the odd power it keeps the sign.

This problem can be simplified to.

(-2/3)^5

And this is the answer :D

Answer:

m is equal to -1 ± 2√3, which is approximately equal to 2.46 and -4.46

Step-by-step explanation:

-4m² + 2m - 11 = -5m²

m² + 2m - 11 = 0

m² + 2m + 1 = 12

(m + 1)² = 12

m + 1 = ± √12

m = -1 ± 2√3

Answer: D

Step-by-step explanation: its best you can get to the a quotient (from Latin: quotiens "how many times", pronounced) is a quantity produced by the division of two numbers. The quotient has widespread use throughout mathematics, and is commonly referred to as the integer part of a division (in the case of Euclidean division), or as a fraction or a ratio (in the case of proper division). For example, when dividing 20 (the dividend) by 3 (the divisor), the quotient is 6 in the Euclidean division sense, and 62/3 in the proper division sense.

Step-by-step explanation:

This has to do with correctly using the distributive property to distribute a negative multiplier.

Answer:

Slope = 2 Y-Intercept = (0, 3)

Step-by-step explanation:

Slope : [tex]\frac{Rise}{Run}[/tex]  which is [tex]\frac{y2 - y1}{x2 - x1}[/tex] from two points: point1 (x1 , y1) and point2 (x2, y2).

For the purpose of getting the slope I will be using point (0, 3) as point 1

and point (-3, -3) as point 2.

If you plug in 0 as x1, 3 as y2, -3 for x2, and -3 for y2:

[tex]\frac{-3 - 3}{-3 - 0}[/tex] = [tex]\frac{-6}{-3}[/tex] = 2

Y-Intercept: The y intercept is the point where the line is touching the y axis. Which in this graph, there is only point (0,3).

Answer:

0.006 L

Step-by-step explanation:

Mass of water = 6kg

Using the relation :

Density = mass / volume

Density of water = 100kg/m³

1000 kg/m³ = 6kg / volume

1000kg/m³ * volume = 6kg

Volume = 6kg / 1000 kg /m³

Volume = 0.006

Answer:

[tex]L_c=25.12ft[/tex]

Step-by-step explanation:

From the question we are told that

Width of circular path [tex]w_c=4ft[/tex]

Inner Diameter [tex]d_i_n=550ft[/tex]

Outer diameter [tex]d_{out}= 550 +2*4[/tex]  (inner diameter +  2 circular path width)

[tex]d_{out}= 550 +8\\d_{out}= 558ft[/tex]

Generally the equation for inner circumference of the circle [tex]C_1[/tex] is mathematically given by

[tex]C_1=\pi d_{in}[/tex]

[tex]C_1=3.14*550[/tex]

[tex]C_1=1727ft[/tex]

Generally the equation for outer circumference of the circle [tex]C_2[/tex] is mathematically given by

[tex]C_2=\pi d_{out}[/tex]

[tex]C_2=3.14*558[/tex]

[tex]C_2=1752.12ft[/tex]

Generally the difference in length of the two circumference [tex]L_c[/tex] is mathematically given by

[tex]L_c=C_2-C_1[/tex]

[tex]L_c=1752.12-1727[/tex]

[tex]L_c=25.12ft[/tex]

The length of the ramp that is on the ground is 72 inches.

An expression is a way of writing a statement with more than two variables or numbers with operations such as addition, subtraction, multiplication, and division.

Example: 2 + 3x + 4y = 7 is an expression.

We have,

Ramp scale drawing dimension:

Height = 1 in

Length = 12 in

Now,

1 in = 6 inches

12 in = 6 x 12 = 72 inches

Thus,

The length of the ramp is 72 inches.

Answer:

24/42

Step-by-step explanation:

42÷7=6

4x6/7x6=24/42

Answer:

Please give brainlliest thanks! :)

so it's a square which means all of the sides are equal.

that means x+7=3x+1

      subtract 1 from both sides

x + 6 = 3x

      subtract x from both sides

6 = 2x

      divide both sides by 2

3 = x

you can do the same for y

2y - 1 = -3y + 14

    add 3y to both sides

5y - 1 = 14

     add 1 to both sides

5y = 15

      divide both sides by 5

y = 3

Answer:

The surface area is 286.5in.

Step-by-step explanation:

7.5 * 11.5 = 86.25 * 2 = 172.5in for two big rectangles

7.5 * 3 = 22.5 for little rectangle

11.5 * 3 = 34.5 * 2 = 69 for two medioum rectangles

7.5 * 3 = 22.5 for the smallest rectangle

22.5 + 69 + 22.5 + 172.5 = 286.5 in SA

Answer: m∠E = 55°

Step-by-step explanation: If a triangle has two equal sides, it is called Isosceles. Another characteristics of this type of triangle is that the angles opposite the equal sides are also congruent.

Triangle ΔEFG has two sides with approximately the same length:

[tex]\overline{GE}[/tex] ≈ [tex]\overline{FG}[/tex]

So, it is an isosceles.

Therefore the opposite angles are m∠E and m∠F.

m∠E = m∠F

m∠E = 55°

Angle at vertex E is 55°.
