Answer:

$4.34

Step-by-step explanation:

Given the information:

We can find out the actual price that Diane bought a bunch of balloons that was marked down 20% is:

= the original price (100% - discount rate)

= 5(100% -20%)

= $4

= The actual price*tax rate

= $4*8.5%

= $0.34

=> the total cost of the bunch of balloons :

The actual price + tax price

= $4 + $0.34

= $4.34

Hope it will find you well.

Answer:

  B' = (5, -4)

Step-by-step explanation:

The picture is illegible, but we think B is (1, 4).

After rotation 180°, both coordinates are negated, so the point is ...

  B" = -(1, 4) = (-1, -4)

After reflection across x=2, the x-coordinate is subtracted from 2·2 = 4:

  B' = (4 -(-1), -4)

  B' = (5, -4)

Answer:

25 : 4

Step-by-step explanation:

Given 2 similar figures with ratio of sides = a : b , then

ratio of area = a² : b²

For the given figures the ratio of corresponding sides is

JK : EF = 20 : 8 = 5 : 2 , thus

ratio of areas = 5² : 2² = 25 : 4

Answer:

I believe the answer is four there is twice as many horses so you would double the amount of original goats.

The number of goats that went with 6 pigs and 10 horses is; 4 goats.

Let the number of horses be h.

Let the number of pigs be p

Let the number of goats be g.

We are told that horses vary directly as goats.

Thus;

h ∝ g

Thus; h = k1g - --(eq 1)

Also, we are told that horses varies inversely as pigs squared.

Thus;

h ∝ 1/p²

h = k2/p² - - - (eq 2)

Where k1 and k2 are constant of proportionality.

When there are 5 horses there are 2 goats. Thus;

5 = 2k1

k1 = 5/2

k1 = 2.5

When there are 10 horses, we will have;

10 = 2.5g

g = 10/2.5

g = 4

Answer:

perimeter of ΔDEF  ≈ 32

Step-by-step explanation:

To find the perimeter of the triangle, we will follow the steps below:

First, we will find the length of the side of the triangle DE and FF

To find the length DE, we will use the sine rule

[tex]\frac{sin E}{e} = \frac{sin F}{f}[/tex]

angle E  = 49 degrees

e= DF = 10

angle F = 42 degrees

f= DE =?

we can now insert the values into the formula

[tex]\frac{sin 49}{10}[/tex] = [tex]\frac{sin 42}{f}[/tex]

cross-multiply

f sin 49° = 10 sin 42°

Divide both-side by sin 49°

f = 10 sin 42° / sin 49°

f≈8.866

which implies DE ≈8.866

We will now proceed to find side EF

To do that we need to find angle D

angle D + angle E + angle F = 180°  (sum of interior angle)

angle D + 49° + 42° = 180°

angle D + 91° = 180°

angle D= 180° - 91°

angle D = 89°

Using the sine rule to find the side EF

[tex]\frac{sin E}{e} = \frac{sin D}{d}[/tex]

angle E = 49 degrees

e= DF = 10

ange D = 89 degrees

d= EF = ?

we can now proceed to insert the values into the formula

[tex]\frac{sin 49}{10}[/tex] = [tex]\frac{sin 89}{d}[/tex]

cross-multiply

d sin 49° = 10 sin 89°

divide both-side of the equation by sin 49°

d= 10 sin 89°/sin 49°

d≈13.248

This implies that length EF = 13.248

perimeter of ΔDEF = length DE + length EF + length DF

                                   =13.248   +  8.866  + 10

                                    =32.144

                                     ≈ 32 to the nearest whole number

perimeter of ΔDEF  ≈ 32

Answer:

y=5

Step-by-step explanation:

Pythagorean theorem states that in a right triangle, the square of the hypotenuse is equal to the sum of the squares of the other two sides.

WY is the perpendicular bisector of XZ.

2x + 3 = 3x - 5

x = 8

5y - 2y = 7 + 8

y = 5

The value of y is 5

Pythagorean theorem states that in a right triangle, the square of the hypotenuse is equal to the sum of the squares of the other two sides.

We have,

WY is the perpendicular bisector of XZ.

We see that,

2x + 3 = 3x - 5

3x - 2x = 3 + 5

x = 8

Now,

We have two right triangles.

∠WXY

WY² = WX² + XY² _____(1)

∠WYZ

WY² = WZ² + YZ² ______(2)

From (1) and (2) we get,

WX² + XY² = WZ² + YZ²

(2y + 7)² + (2x + 3)² = (5y - 8)² + (2x + 3)²

(2y + 7)²  = (5y - 8)²

2y + 7 = 5y - 8

5y - 2y = 7 + 8

3y = 15

y = 5

Thus,

The value of y is 5

Answer:

Perimeter = 98 cm

Area = 596 [tex]cm^{2}[/tex]

Step-by-step explanation:

Please refer to the attached image for the resultant figure when a quadrant of circle with radius 7 cm is cut from a rectangle of sides 30 cm and 25 cm.

Perimeter of a figure = Sum of all its sides + Perimeter of circle

Quadrant of a circle is one fourth of a circle and there are 4 such quadrant of a circle, so eventually there is one complete circle in this figure.

The sides of this resultant figure = 30 - 14 = 16 cm

and 25 - 14 = 11 cm

So perimeter of this figure = 16 + 11 + 16 + 11 + Perimeter of circle

[tex]\Rightarrow 54 + 2 \pi r\\\Rightarrow 54 + 2 \times \dfrac{22}{7} \times 7\\\Rightarrow 54 + 44 = 98 cm[/tex]

To find area of this figure = Area of rectangle - Area of circle

Area of rectangle = Length [tex]\times[/tex] Width

[tex]\Rightarrow 30 \times 25 = 750\ cm^{2}[/tex]

Area of circle = [tex]\pi r^{2}[/tex]

[tex]\Rightarrow \dfrac{22}{7} \times 7^{2} = 154\ cm^{2}[/tex]

So, area of figure = 750 - 154 = 596 [tex]cm^{2}[/tex]

Answer:

x = -.4

Step-by-step explanation:

3x + 5.2 = 2 - 5x

Add 5x to each side

3x+5x + 5.2 = 2 - 5x+5x

8x +5.2 = 2

Subtract 5.2 from each side

8x +5.2 - 5.2 = 2-5.2

8x = -3.2

Divide each side by 8

8x/8 = -3.2/8

x = -.4

Answer:

x= -0.4

Step-by-step explanation:

3x+5.2=2-5x

Add 5x to both sides

8x+5.2=2

Subtract 5.2 from both sides

8x= -3.2

Divide both sides by 8

x= -0.4

Answer:

[tex]x = \frac{k + c}{4}[/tex]

Step-by-step explanation:

Given:

[tex]4x - c = k[/tex]

Solve for:

[tex]x[/tex]

Solution:

(1) Let's move all of components that do not contain [tex]x[/tex] (our target) to the right side (notice the change of sign of [tex]c[/tex] from negative to positive):

[tex]4x = k + c[/tex]

(2) Let's divide both sides of equation by 4:

[tex]\frac{4x}{4} = \frac{k + c}{4}[/tex]

(3) Now, we simplify the left side:

[tex]x = \frac{k + c}{4}[/tex]

This is the solution.

Hope this helps!
