Answer:

It $29.75

Step-by-step explanation:

Answer:

Orignal Price: $35

Discount Price: $29.75

Step-by-step explanation:

The original price is $35 since it says 15% off of $35. To get the discount price you would use the equation 35-15%, which would give you $29.75. Your new price is $29.75.

Answer:

Number of trucks = 28

Number of cars = 14

Number of SUVs = 46

Total number of vehicles = 88

Step-by-step explanation:

Let T = the number of trucks, C = the number of cars, and S = the number of SUVs washed.

We are told :

They washed twice as many cars as trucks.

Hence: T = 2C

They washed a total of 28 trucks and cars and SUVs

Number of trucks = 28

Number of Cars =

T= 2 C

C = T/2

C = 28/2

C = 14

The number of trucks washed was 2 fewer than half the total number of cars and SUVs washed.

T = 1/2(C + S) - 2

T = 28

C = 14

Hence:

28 = 1/2(14 + S) - 2

28 = 1/2(14) + 1/2(S) - 2

28 = 7 - 2 +S/2

28 - 7 + 2 = S/2

30 - 7 = S/2

23 = S/2

S = 23 × 2

S = 46

Hence, number of SUVs = 46

Total number of vehicles = 28 + 14 + 46

= 88

Answer:

The answer is 1/9 square yard. I hope this helps!

Answer: C. 1/9 sq yd

Step-by-step explanation:

To find the area of a square, you do the side length squared. (1/3)^2 is the same as (1/3) * (1/3). Multiply the numerators together to get 1 * 1 = 1 and the denominators to get 3 * 3 = 9. This gives you 1/9.

Since triangle LKJ is similar to triangle LNM,

we know that JK / MN = LK / LN.

JK = 40

MN = 25

LK = LN + KN = LN + 12

LN = ?

Sub these values in and solve for LN...

40 / 25 = (LN + 12) / LN

Simplifying and distributing...

1.6 = 1 + 12 / LN

Subtracting 1 from on both sides...

0.6 = 12 / LN

Multiplying both sides by LN...

0.6 * LN = 12

Dividing both sides by 0.6...

LN = 20

Answer:

1/3

Step-by-step explanation:

5/6 - 1/2

note that you could also write 1/2 as 3/6 since when divided you get half once again .

5/6- 3/6 = (5-3)/6= 2/6 = 1/3

Answer:

The answer is

[tex] \huge \frac{1}{3} [/tex]

Step-by-step explanation:

[tex] \frac{5}{6} - \frac{1}{2} \\ [/tex]

To solve this first find the common denominator

From the question the common denominator is 6

So we have

[tex] \frac{5}{6} - \frac{1}{2} = \frac{5 - 3}{6} = \frac{2}{6} = \frac{1}{3} \\ [/tex]

We have the final answer as

[tex] \frac{1}{3} \\ [/tex]

Answer:

y = 7.2

Step-by-step explanation:

Given that y varies directly as x then the equation relating them is

y = kx ← k is the constant of variation

To find k use the condition y = 10 when x = 25, then

10 = 25k ( divide both sides by 25 )

[tex]\frac{10}{25}[/tex] = 0.4 = k

y = 0.4x ← equation of variation

When x = 18, then

y = 0.4 × 18 = 7.2

Answer:

60°

Step-by-step explanation:

Given:

QP and QR are tangent segments

∠PCR = 120°

Find:

∠PQR

Tangent lines always intersect a circle at one point. This means that the line from the center of the circle to the point of intersection would be the radius. This also means that the tangent line is perpendicular to the radius of the circle.

Therefore...

∠CPQ=90°

∠CRQ=90°

Using the diagram, we can conclude that Figure CPQR is a quadrilateral. We need to find the sum of the interior angles of the Figure CPQR.

The formula to find the sum of the interior angles of a figure is...

[tex](n-2)\times180[/tex]

Note that n represents the amount of sides the figure has.

In this case Figure CPQR has 4 sides therefore...

[tex](4-2)\times180=2\times180=360^{\circ}[/tex]

Now let's set up an equation to find ∠PQR...

∠PCR + ∠CPQ + ∠CRQ + ∠PQR = 360°

Substitute the measures of the known angles into the equation:

120° + 90° + 90° + ∠PQR = 360°

        120° + 180° + ∠PQR = 360°

                  300° + ∠PQR = 360°

Subtract 300° from both sides

∠PQR = 60°

Answer:

h = 2.5 cm

Step-by-step explanation:

the volume (V) of a prism is calculated as

V = Al ( A is the area of triangular base and l the length )

A = [tex]\frac{1}{2}[/tex] bh = [tex]\frac{1}{2}[/tex] × 4 × h = 2h and l = 7

given V = 35 , then

2h × 7 = 35

14h = 35 ( divide both sides by 14 )

h = 2.5 cm

A two-way frequency table for these 82 students is shown in the table attached below.

A two-way frequency table can be defined as a table that is used for the graphical representation of frequencies or relative frequencies that are associated with two (2) categorical variables.

This ultimately implies that, a two-way frequency table is mainly used to show, analyze, and examine the relationships between two (2) categorical variables.

Generally, one of the two (2) categorical variables is represented by rows while the other is represented by columns.

Answer:

Step-by-step explanation:

Vertices of the quadrilateral are (-4, 1), (-3, 2), (-1, 2) and (-2, 1).

If the given quadrilateral is dilated by ta scale factor of 1.5 about the origin.

Rule for the dilation,

(x, y) → (kx, ky) [k = scale factor]

New vertices of the quadrilateral after the transformation will be,

(-4, 1) → (1.5×4, 1.5×1)

        → (-6, 1.5)

(-3, 2) → (-4.5, 3)

(-1, 2) → (-1.5, 3)

(-2, 1) → (-3, 1.5)

Now the new points are rotated by 90° clockwise about the origin,

Rule for the rotation of the points,

(x, y) → (y, -x)

So the new vertices will be,

(-6, 1.5) → (1.5, 6)

(-4.5, 3) → (3, 4.5)

(-1.5, 3) → (3, 1.5)

(-3, 1.5) → (1.5, 3)

We can plot these points on the graph to form a new (image) quadrilateral.
