Answer:

≈ 66.5 m

Step-by-step explanation:

Using the sine ratio in the right triangle

sin12° = [tex]\frac{opposite}{hypotenuse}[/tex] = [tex]\frac{d}{320}[/tex] ( multiply both sides by 320 )

320 × sin12° = d , then

d ≈ 66.5 m ( to 1 dec. place )

[tex]X\leq 1[/tex]

Because the line show X is 1 or less.

Answer:

X [tex]\leq[/tex] 1

Step-by-step explanation:

Since the dot is solid that means it includes 1

and since the line is going towards negative infinity that is why it is less than

So X is less than or equal to 1 which is the first answer

Answer:

games is 40

Step-by-step explanation:

you know that 20% of games is 8. let's take a look at this from a fractions view. 1/5 of 100 is 20. so if 8 is 1/5 of Games, multiply 8 x 5 to find the whole, which is 40, the answer!

I’m pretty sure it’s 30%

Answer:

Step-by-step explanation:

1)  because there are 10 total boxes in box 1  and they want 2/5 of them color in 4 boxes to make 4/10  which can reduce to 2/5

2) they say make it unlikey that a blue box will be picked.. so color in one box

3) now don't color any of the boxes.. so no matter which boxes is picked.. there isn't any blue ones. :)

Answer:

Yes the amount Greta has budgeted ($1,500) is enough to complete the project which will cost $1,443.75

Step-by-step explanation:

The amount Greta has budgeted to have a concrete patio = $1,500

The cost (per square foot) of the concrete, C/Ft² = $5.50/ft²

From the dimension of the backyard, we have;

The total area, A = The area of a rectangle + The area of a trapezium

The area of the rectangle = 6 ft. × 28 ft. = 168 ft.²

The area of the trapezium = (8 ft. + (28 ft. - 15 ft.))/2 × (15 ft. - 6 ft.) = ((8 ft. + 13 ft.)/2) × 9 ft. = 94.5 ft.²

The total area, A = 168 ft.² + 94.5 ft.² = 262.5 ft.²

The total cost of the concrete, C = A × C/Ft²

∴ C = 262.5 ft.² × $5.50/ft² = $1,443.75

Therefore, given that Greta budgeted $1,500 for the project which is more than the $1,443.75 required, Greta has budgeted enough money to complete the project

Step-by-step explanation:

x + y = 30

2x + 4y = 84

___________

2x+2y=60

2x+4y=84

_________

-2y=-24/-2y

y=12

2x+4(12)=84

2x+48=84

2x=84-48

2x/2=36/2

X=18

Answer:

Yes, she is correct.

Step-by-step explanation:

In the question it is given that Avannah wants to buy food for her dog that may lasts for 2 weeks (or 14 days). Dogs must serve food according to their breed and their weight. The diet of every dog is different. Avannah needs to feed her dog three times a day. So a 20 lb bag of food is enough for her to feed her dog for 2 weeks.

So it is the correct decision to get a 20 lb bag of food for her dog. It will last for 14 days.

Answer:

a) (2, 0.5)  (4, 1)

b) V(n) = 0.25n

c) $2.50

d) # quarters = independent

value = dependent

Step-by-step explanation:

The independent value is the number of quarters and the dependent variable is the value of cents and the  equation that represents this function is,

[tex]v(n)=25\times n\rm \;\;cents[/tex]

Algebraic expression are the expression which consist the variables, coefficients of variables and constants.

The algebraic expression are used to represent the general problem in the mathematical way to solve them.

Steps to write down the simple algebraic expression-

There is total 25 cent is 1 quarter. Thus, when if there are 2 quarters, then the value of cent is 50 and when there are 4 quarters, then the value of cents is 100 cents.

Hence, the two pairs should be as,

(2, 50), (4, 100)

As, v is the value of quarters in cents. There is total 25 cent is 1 quarter. The total quarter is n. Thus, the function can be given as,

[tex]v(n)=25\times n\rm \;\;cents[/tex]

Put the value 10 on the place of n in the above equation as,

[tex]v(10)=25\times (10)\\v(10)=250\rm cents[/tex]

The output when the input is 10 is 250 cents.

The independent value is the number of quarters and the dependent variable is the value of cents.

Hence, the independent value is the number of quarters and the dependent variable is the value of cents and the  equation that represents this function is,

[tex]v(n)=25\times n\rm \;\;cents[/tex]

Answer:

40 yards greater

Step-by-step explanation:

Perimeter of a triangle, P = a + b + c

perimeter of a triangular field with sides that measure 92 yards, 95 yards, and 84 yard

P = a + b + c

= (92 + 95 + 84) yards

= 271 yards

perimeter of a triangular field with sides that measure 85 yards, 90 yards, and 56 yards

P = a + b + c

= (85 + 90 + 56) yards

= 231 yards

perimeter of a triangular field with sides that measure 92 yards, 95 yards, and 84 yard is 40 YARDS GREATER than perimeter of a triangular field with sides that measure 85 yards, 90 yards, and 56 yards

I believe that 95 isn't one of the measures

Answer:

B)  y = -3x+2

Step-by-step explanation:

plug (2,-4) and -3 into y = mx + b to find 'b'

-4 = -3(2) + b

b = -4+6 = 2

Answer:

Step-by-step explanation:

3x = y        ------------(I)

y = 2x + 22 ---------------(II)

Substitute y = 2x + 22 in equation (I)

3x = 2x + 22           {Subtract 2x form both sides}

3x -2x = 22              

      x = 22

Plugin x = 22 in equation (I)

3*22 = y

y = 66

Answer:

Step-by-step explanation:

3x = y

y = 2x + 22

3x = 2x + 22      

3x -2x = 22              

x = 22

3x22 = y

66=y

Answer:

131°

Step-by-step explanation:

to find the total degrees of this polygon, we use the equation

=> n - 2 × 180°                         (n= number of sides)

5 - 2 × 180° = 540°

now by using angle sum property,

540° = 80° + 148° + 81° + 100° + [tex]x[/tex]°

540° = 409° + [tex]x[/tex]°

[tex]x[/tex]° = 540° - 409°

[tex]x[/tex]° = 131°

3) (-1)(-3)

Answer:

3,3,4,6,6

4,4,5,6,7

5,5,6,6,8

Step-by-step explanation:

mode = n

median= n+1

mean = n+2

Range = n+3

let sets:

a,b,c,d,e

mode = n, at least two of them are the same and equal to n

n,n,c,d,e

median belong to the set, in ascending order:

n,n,n+1,d,e

which means d,e ≥ n+1, d≠e

mean is n+2

5(n+2)=n+n+n+1+d+e

2n+9=d+e

Assume e is the maximum:

Range is n+3:

e-n=n+3

e=2n+3

d=6≥n+1

n≤5,

Set is n,n,n+1,6,n+3

n+1≤6≤n+3
