Answer:

x=16

Step-by-step explanation:

angle TVQ = angle VWS (if they are parallel they can be said as corresponding angles)

5x-22 = 3x+10

5x-3x = 10+22

2x = 32

x = 32/2

x = 16

Answer:

B

Step-by-step explanation:

If PQ and RS are to be parallel, then

∠ TVQ = ∠ VWS ( corresponding angles ) , that is

5x - 22 = 3x + 10 ( subtract 3x from both sides )

2x - 22 = 10 ( add 22 to both sides )

2x = 32 ( divide both sides by 2 )

x = 16

For PQ and RS to be parallel then x = 16

Answer:

Step-by-step explanation:

If cost is directly proportional to speed, then the equation for this is

£ = ks, where k is the constant of proportionality. We need to solve for this first.

400 = k4 so

100 = k. Now we will use that k value in the next equation to find the cost of a 6GHz processor:

£ = (100)(6) so

£ = 600

Answer:

s(t) = -4.9t² + 39.2t

Step-by-step explanation:

Given the projectile motion of an object can be modeled using s(t) = gt2 + v0t + s0, where g is the acceleration due to gravity, t is the time in seconds since launch, s(t) is the height after t seconds, v0 is the initial velocity, and s0 is the initial height. The acceleration due to gravity is –4.9 m/s²

Given

g = -4.9m/s²

v0 = 39.2m/s

s0 = 0m (the initial height)

On substituting into the formula;

s(t) = gt² + v0t + s0

s(t) = -4.9t² + 39.2t + 0

s(t) = -4.9t² + 39.2t

This gives the equation that models the height

Answer:

C

Step-by-step explanation:

Answer:

option c is correct

Step-by-step explanation:

y = 2x +5

5 = 2*0 +5

5 = 0 +5

5=5

y = 2x +5

9 = 2*2 + 5

=9 = 4 +5

9=9

y = 2x +5

13 = 2*4 +5

13 = 8 + 5

13 = 13

therefore option c is correct because it satisfies all the elements of x and y of the given function when we substitute the values.

Answer:

14

Step-by-step explanation:

(f - g)(x)

= f(x) - g(x)

= 3x² + 1 - (1 - x)

= 3x² + 1 - 1 + x

= 3x² + x

Then

(f- g)(- 2)

= 3(- 2)² + 2

= 3(4) + 2

= 12 + 2

= 14

Answer:

x = -6

Step-by-step explanation:

[tex]x+\frac{2}{3}=\frac{8}{9}x\\\\x = \frac{8}{9}x - \frac{2}{3}\\\\x - \frac{8}{9}x= -\frac{2}{3}\\\\\frac{9}{9}x-\frac{8}{9}x=\frac{2}{3}\\\\\frac{1}{9}x=-\frac{2}{3}\\\\x=-\frac{2}{3}*\frac{9}{1}\\\\x=(-2)*3\\\\x = -6[/tex]

Answer:

x = [tex]\frac{2}{9}[/tex]

Step-by-step explanation:

Given

x + [tex]\frac{2}{3}[/tex] = [tex]\frac{8}{9}[/tex] ( multiply through by 9 to clear the fractions )

9x + 6 = 8 ( subtract 6 from both sides )

9x = 2 ( divide both sides by 9 )

x = [tex]\frac{2}{9}[/tex]

Step-by-step explanation:

Adjacent angles sit next to each other, and don't overlap.

Answer:

w = 10

Step-by-step explanation:

6w+18-9w = -12

Combine like terms

-3w + 18 = -12

Subtract 18 from each side

-3w +18- 18 = -12 -18

-3w = -30

Divide each side by -3

-3w/-3 = -30/3

w = 10

Answer:

w = 10

Step-by-step explanation:

6 w + 18 - 9 w = - 12

combine like terms

6 w - 9 w + 18 = - 12

- 3 w + 18 = - 12

subtract each side by 18

- 3 w + 18 - 18 = - 12 -18

- 3 w = - 30

Divide each side by - 3

- 3 w / - 3 = - 30 / - 3

w = 10

Step-by-step explanation:

We need to find the side of the square garden.

Area of square garden = 484 sq.feet

side²   = 484

[tex]side = \sqrt{484}\\\\side = \sqrt{2*2*11*11} \\\\side = 2 * 11 = 22 feet[/tex]      

Answer:

111 m²

Step-by-step explanation:

A rectangle is a quadrilateral (has four sides and four angle) with two pairs of parallel sides. Opposite sides of a rectangle are equal to each other. Also all the angles of a rectangle are 90° each.

The area of a rectangle = length * width

For rectangle 1, length = 12 m, width = 3 m

Therefore area of rectangle 1 = length * width = 12 m * 3 m = 36 m²

For rectangle 2, length =(12 m - 3 m - 3 m) = 6 m, width =(15 m - 10 m) =5 m

Therefore area of rectangle 2 = length * width = 6 m * 5 m = 30 m²

For rectangle 3, length = 15 m, width = 3 m

Therefore area of rectangle 3 = length * width = 15 m * 3 m = 45 m²

Area of composite shape = Area of rectangle 1 + Area of rectangle 2 + Area of rectangle 3

Area of composite shape = 36 m² + 30 m² + 45 m² = 111 m²

Answer:

x = 70

Step-by-step explanation:

The two angles are same side interior angles and same side interior angles add to 180

45+ (2x-5) = 180

Combine like terms

2x +40 = 180

Subtract 40 from each side

2x+40-40 =180-40

2x =140

Divide by 2

2x/2 = 140/2

x = 70

Answer:

x=70

Answer: [tex]6.2\ cm[/tex]

Step-by-step explanation:

Given

The volume of the sphere is [tex]V=996\ cm^3[/tex]

Volume of sphere is given by [tex]V=\dfrac{4}{3}\pi r^3[/tex]

Insert the values

[tex]\Rightarrow 996=\dfrac{4}{3}\times \dfrac{22}{7}r^3\\\\\Rightarrow r^3=\dfrac{996\times 21}{88}\\\\\Rightarrow r=6.2\ cm[/tex]

Thus, the radius of the sphere is [tex]6.2\ cm[/tex]

Answer:

1.06 or 1 1/15

Step-by-step explanation:

So, basically what we need to do is reverse the steps.

So now it goes like this:

We start with 1 5/6(1.83)

Then we add 7/18(0.389)

Then we multiply by 1 1/5(1.2)

Then finally, we divide by 2 1/2(2.5)

This will get us our answer. So:

1.83+0.389 = 2.219

2.219*1.2 = 2.6628

2.6628/2.5 = 1.06

This is 1.06 in decimal form, or 1 1/15 in fraction form

Hope this helps!

This can also be double checked, if you plug it into the orginal equation:

1.06, then you multiply by 2.5: 1.06*2.5= 2.6628

2.6628, then you divide by 1.2: 2.6628/1.2= 2.219

Then finally, 2.219 and subtract 7/18: 2.219-0.389= 1.83

So we have double checked, and our answer is still 1.06.

Answer: B) 0.50x+15=25

Step-by-step explanation:

So we know she earns 15 dollars each week and she wants to get 25 dollars.

So far our equation is ?+15=25

For every customer on her paper route she gets $0.50. For 1 customer she'd get $0.50. For 2 she'd get $1. As you can see the customers she gets is multiplied by 0.50 to see how much money she makes. So, for x customers she'd get 0.50x dollars.

So now we can add that to our equation

0.50x+15=25

Answer:

(x-2)^2 +(y+5)^2=4^2

Step-by-step explanation:

x minus 2 squared + y plus 5 squared = radius squared

Answer:

(x-2) ^2 + ( y+5)^2 = 16

Step-by-step explanation:

The equation for a circle is given by

(x-h) ^2 + ( y-k)^2 = r^2 where (h,k) is the center and r is the radius

(x-2) ^2 + ( y- -5)^2 = 4^2

(x-2) ^2 + ( y+5)^2 = 16
