Answer:

1.43 degrees

Step-by-step explanation:

Think of this as a triangle with an x (horizontal) value of 400 and a y (vertical) value of 10.

Using this train of thought, we can use SOHCAHTOA to find that the tan of some angle (we will use Ф to represent this angle) is equal to the opposite (vertical) value divided by the adjacent (horizontal) value.

As an equation, it looks like this: tan (Ф) = 10/400.

We can use the arctan to find Ф from this equation: arctan (10/400) = Ф

Therefore, Ф is about 1.43 degrees.

Answer:

-(3x + 1)/x

Step-by-step explanation:

(x + 2)/x  - 2 - (x + 3)/x  - 1

(x + 2)/x  -  (x + 3)/x  - 2 - 1

(-1)/x - 3

-1/x - 3x/x

(-1 - 3x)/x

-(3x + 1)/x

Answer:

Caleb and Devon each bowled for [tex]10[/tex] hours and spent [tex]\$55[/tex].

Step-by-step explanation:

Equations:

Where:

System of equations:

[tex]\begin{cases}y=4x+15\\y=5x+5\end{cases}[/tex]

Solve for x

Step 1: Substitute the second equation into the first.

[tex]\implies 4x+15=5x+5[/tex]

Step 2: Subtract [tex]5x[/tex] from both sides

[tex]\implies 4x-5x+15=5x-5x+5[/tex]

[tex]\implies -x+15=5[/tex]

Step 3: Subtract [tex]15[/tex] from both sides.

[tex]\implies -x+15-15=5-15[/tex]

[tex]\implies -1x=-10[/tex]

Step 4: Divide both sides by [tex]-1[/tex] .

[tex]\implies \dfrac{-1x}{-1}=\dfrac{-10}{-1}[/tex]

[tex]\implies \boxed{x=10}[/tex]

Solve for y

Step 1: Substitute the found [tex]x[/tex] value into one of the system of equations.

[tex]\implies y=4(10)+15[/tex]

Step 2: Multiply and add.

[tex]\implies y=40+15[/tex]

[tex]\implies \boxed{y=55}[/tex]

Therefore, Caleb and Devon each bowled for 10 hours and spent $55.

Step-by-step explanation:

there are different ways you could do it using the elimination and substitution method.

Answer:

x = 1 and y = -28

(1,-28)

Elimination & Substitution method

8x + 4y = -104 →multiply by 1

4x + y = - 24 →multiply by 4

8x + 4y = -104

16x + 4y = -96

____________-

-8x = -8

x = -8/-8

[tex] \boxed{x = 1}[/tex]

Substitute x

4x + y = -24

4(1) + y = -24

4 + y = -24

y = -24 - 4

[tex] \boxed{y = - 28}[/tex]

Answer:

84.5

Step-by-step explanation:

1: 96 - 13 to get difference = 83

2: 83 - 5 = 78

3: 78 + 3 = 81

4: (83 + 78 + 81 + 93) / 4 = 84.5

Step-by-step explanation:

in the strange US system there is suddenly a metric relationship :

1 ton = 2000 pounds.

FYI - an actual (metric) ton is 1000 kg, which is

2,204.6226218488 pounds.

anyway, as 1 ton = 2000 pounds, then 4 tons = 4×2000 = 8000 pounds.

8000 pounds cost $28,080.00.

1 pound costs therefore

28080/8000 = $3.51

[tex]29 +\sqrt[1/3]{z}[/tex]

Step-by-step explanation:

I think this is it i might be wrong because it might be [tex]29 + \sqrt[z]{1/3}[/tex]

if i got it correct then please mark brainliest i rlly need it

The variable expression for "twenty-nine more than one-third of the square of z" is (1/3) × z² + 29.

Given information:

29 greater than one-third of the square of z

Let's break down the sentence into parts to create a variable expression as follows:

The square of z as show below:

z²

One-third of the square of z given as:

(1/3) × z²

Twenty-nine more than one-third of the square of z as given below:

(1/3) × z² + 29

So, the variable expression for "twenty-nine more than one-third of the square of z" is (1/3) × z² + 29.

Answer:

6

Step-by-step explanation:

2 + 6 = 8

6 + 6 = 12

3 + 6 = 9

? = 6

The value of the center digit which satisfies the given scenario is 6.

A polygon is a closed more than two-sided and can be made up of a finite number of straight line segments and is a type of planar figure in geometry.

Each line of the polygonal circuit's segments are referred to as its edges or sides.

If we observe the given polygon carefully every opposite side has a difference of 6 from the bigger number to the smaller number.

9 - 3 = 6.

8 - 2 = 6.

12 - 6 = 6.

So, In the center of the polygon or a hexagon, the number should be 6.

Answer:

11.625 pounds

Step-by-step explanation:

x = weight of dog

7 3/4 = 2/3(x)

7 3/4 divided by 2/3 = x

x = 11.625 pounds

Answer:

11 5/8

Step-by-step explanation:

let 'd' = dogs weight

7 3/4 equals 2/3d

change 7 3/4 to an improper fraction:  31/4

to isolate 'd', each side needs to be multiplied by 3/2

31/4 × 3/2 = d

93/8 = d

11 5/8 equals dogs weight

Perimeter = 5.67

Step-by-step explanation:

AB = sqrt{-1 - (0)} + (-2 - (-4)}

Multiply -1 by 0

sqrt(-1 + 0 - 2 - (-4)

-1 by -4

sqrt(-1 + 0 - 2 + 4

Add -1 and 0

sqrt(-1 - 2 + 4)

Subtract 2 from -1

sqrt(-3 + 4)

Add

Sqrt(1) > 1

BC = sqrt{5 - (-1)} + {-3 - (-2)}

Multiply -1 by -1

sqrt(5 + 1 - 3 - (-2)

-1 by -2

sqrt(5 + 1 - 3 + 2

Add 5 and 1

sqrt(6 - 3 + 2)

Add 3 and 2

Sqrt(5) > 2.23

AC = sqrt{5 - 0} + {-3 - (-4)}

Multiply -1 by 0

sqrt(5 + 0 - 3 - (-4)

-1 by -4

sqrt(5 + 0 - 3 + 4)

Add 5 and 0

sqrt(5 - 3 + 4)

Subtract 3 from 5

sqrt(2 + 4)

Add

Sqrt(6) > 2.44

Perimeter = AB + BC + AC

Sqrt(1) + Sqrt(5) + Sqrt(6) = 1 + 2.23 + 2.44 = 5.67
