Answer:

A

Step-by-step explanation:

If 7 out of 9 voted to plant, that means 2 voted against

so the ratio we are looking at here for vote for and vote against is 7:2

So let the total that voted be x

7/9 * x = 119

x = (9 * 119)/7

x = 153

9514 1404 393

Answer:   The slope is 5/4  and the  y intercept will  be 2

Step-by-step explanation:

First convert the equation to slope intercept form ( y = mx+b)  where m will be the slope and b will be the y intercept.

5x - 4y = -8      Subtract 5x from both sides

-5x             -5x

  -4y =  -5x - 8     Divide both sides by -5

y =  5/4x  + 2

Answer:

[tex]V(x) = -\frac{340}{3}x +2220[/tex]

[tex]V(8) = 1313.3[/tex]

Step-by-step explanation:

Given

Let x represent years and V represents the value.

So, we have:

[tex](x_1,v_1) = (0,2220)[/tex]

[tex](x_2,v_2) = (6,1540)[/tex]

Solving (a): The linear function

First, we calculate the slope (m)

[tex]m = \frac{v_2 - v_1}{x_2 - x_1}[/tex]

This gives:

[tex]m = \frac{1540-2220}{6-0}[/tex]

[tex]m = \frac{-680}{6}[/tex]

[tex]m = -\frac{340}{3}[/tex]

The linear function is calculated using:

[tex]v - v_2 = m(x - x_2)[/tex]

Where:

[tex](x_2,v_2) = (6,1540)[/tex]

[tex]m = -\frac{340}{3}[/tex]

So, we have:

[tex]v - 1540 = -\frac{340}{3}(x - 6)[/tex]

Open bracket

[tex]v - 1540 = -\frac{340}{3}x +\frac{340}{3}* 6[/tex]

[tex]v - 1540 = -\frac{340}{3}x +680[/tex]

Make v the subject

[tex]v = -\frac{340}{3}x +680+1540[/tex]

[tex]v = -\frac{340}{3}x +2220[/tex]

So, the function is:

[tex]V(x) = -\frac{340}{3}x +2220[/tex]

Solving (b): When x = 8

Substitute 8 for x in [tex]V(x) = -\frac{340}{3}x +2220[/tex]

[tex]V(8) = -\frac{340}{3}*8 +2220[/tex]

[tex]V(8) = -\frac{340*8}{3} +2220[/tex]

[tex]V(8) = -\frac{2720}{3} +2220[/tex]

Take LCM

[tex]V(8) = \frac{-2720+2220*3}{3}[/tex]

[tex]V(8) = \frac{-2720+6660}{3}[/tex]

[tex]V(8) = \frac{3940}{3}[/tex]

[tex]V(8) = 1313.3[/tex]

Hence, its value after 8 years is 1313.3

Answer:

The inequality describes all possible value of x is 14 < x < 32 ⇒ D

Step-by-step explanation:

In any triangle:

In the given figure

∵ ABC is a triangle

∵ AC = 9 and BC = 21

∵ AB is the third side of the triangle

→ By using the rules above

∴ BC - AC < AB < BC + AC

∵ AB = x - 2

→ Substitute their values in the inequality above

∵ 21 - 9 < x - 2 < 21 + 9

∴ 12 < x - 2 < 30

→ Add 2 to the 3 terms

∴ 12 + 2 < x - 2 + 2 < 30 + 2

∴ 14 < x < 32

∴ The inequality describes all possible value of x is 14 < x < 32

Answer:

y = 10

Step-by-step explanation:

Use the substitution method since you already know what x equals.

4y - 9(y - 3) = -23

Simplify:

4y - 9y + 27 = -23

Combine like terms:

-5y + 27 = -23

Isolate y by subracting 27 from both sides:

-5y = -50

Divide by -5 to get y by itself:

-5/-5 = y

-50/-5 = 10

Answer:

≈ 77 cm²

Step-by-step explanation:

The area of the shaded portion is calculated as

area of outer sector - area of inner sector

= (πR² - π r²) × [tex]\frac{60}{360}[/tex] ( R is the outer radius, r is the inner radius )

= (π × 14² - π × 7² ) × [tex]\frac{1}{6}[/tex]

= (196π - 49π ) ÷ 6

= 147π ÷ 6

≈ 77 cm² ( nearest whole number )

Answer:

[tex]A_s=76.97\ cm^2[/tex]

Step-by-step explanation:

Circular Sector

It's the portion of a circle enclosed by two radii and an arc. The area of a sector is calculated as follows:

[tex]\displaystyle A=\frac {r^{2}\theta }{2}[/tex]

Where r is the radius and θ is the central angle expressed in radians. The central angle will be converted to radians:

[tex]\theta=60*\frac{\pi}{180}=1.0472\ rad[/tex]

The shaded region in the figure can be obtained by subtracting the smaller sector A2 area from the larger sector area A1:

[tex]A_s=A_1-A_2[/tex]

The larger area is calculated with a radius of r1=14 cm:

[tex]\displaystyle A_1=\frac {14^{2}*1.0472 }{2}[/tex]

[tex]\displaystyle A_1=102.626\ cm^2[/tex]

The smaller area is calculated with r2=7 cm:

[tex]\displaystyle A_2=\frac {7^{2}*1.0472 }{2}[/tex]

[tex]\displaystyle A_2=25.656\ cm^2[/tex]

The shaded area is:

[tex]A_s=102.626\ cm^2-25.656\ cm^2[/tex]

[tex]\boxed{A_s=76.97\ cm^2}[/tex]

Step-by-step explanation:

Answer:

A)

Side DF=3

Side EF=6/5

Bye

The values of DF and EF are 3 and 6/5 respectively. (option A)

When two triangles are similar, then their corresponding angles are congruent and corresponding sides are in equal proportion.

Given that, Δ ABC ~ Δ DEF

The proportion = AB/DE = BC/EF = AC/DF = 5/3

2/EF = 5/3

EF = 6/5

5/DF = 5/3

DF = 3

Hence, The values of DF and EF are 3 and 6/5 respectively. (option A)

Answer:

(3,-5)

Step-by-step explanation:

its the last answer

Answer:

(3,-5)

Step-by-step explanation:

Hi there!

Since the dot is in the fourth quadrant, our x value will have to be positive. If the value was negative, it would be in the third quadrant.

If you think about the dot’s relation to the y axis, it is below the point of origin, or y = 0, so the y-value will have to be negative.

The only answer that fits this criteria is (3,-5)
