Find the area of a square with sides of length 1/3 yard. please help fast!
A. 1/3 sq yd
B. 14 sq yd
C. 1/9 sq yd
D. 2/9 sq yd
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.

Decrease £16855.21 by 13.5%
Give your answer rounded to 2 DP.
Answer:
14,579.76
Step-by-step explanation:
New value =
16,855.21 - Percentage decrease =
16,855.21 - (13.5% × 16,855.21) =
16,855.21 - 13.5% × 16,855.21 =
(1 - 13.5%) × 16,855.21 =
(100% - 13.5%) × 16,855.21 =
86.5% × 16,855.21 =
86.5 ÷ 100 × 16,855.21 =
86.5 × 16,855.21 ÷ 100 =

Answer:
C) (0, 2)
Step-by-step explanation:
The y-intercept is the y value when x = 0.
Another way to reword that is when the graph crosses the y-axis.
We see from the graph that it crosses the y-axis at 2. Therefore, our y-intercept is (0, 2).
Suppose y varies directly as x, and y = 10 when x = 25. Find y when x = 18.
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°

A car dealership paid $9,000 for a car. The sticker price is $10,395 for a customer to buy the car. a. What’s the markup in dollars? b. By what percent is the markup?
Answer:
1) To determine how much the change of $9,000 to $10,395, we must subtract 9,000 from 10,395;
10,395 - 9,000 = $1,395 is the change in price (an increase).
Formula to find percentage of change;
Change in price/original amount x 100% (100/100)
Replace those values:
1,935 (change in price/increase) 100
_____ x _____ = %0.215
9,000(original amount) 100

The prism shown has a volume of 35cm³
Work out h, the height of the triangular cross section.
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 high school choir had a car wash to raise money. The number of trucks washed was 2 fewer than half the total number of cars and SUVs washed. They washed twice as many cars as trucks. They washed a total of 28 trucks and cars and SUVs. Let T = the number of trucks, C = the number of cars, and S = the number of SUVs washed. Which ordered triple, (T, C, S) represents the solution to the system below? Verify your answer fully in the box provided.
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

Danielle sold a certain number of tickets to the school play, d. Sara sold 4 more tickets to the school play than the number Danielle sold. Brett sold 3 times as many as Danielle sold. The number of tickets that the 3 students sold altogether can be represented by the expression below. d+d+4+3d
Answer:
5d+4
Step-by-step explanation:
Number of ticket sold by Daniel = d .... 1
If Sara sold 4 more tickets to the school play than the number Danielle sold, the total number sold by Sarah is expressed as d+4 .... 2
If Brett sold 3 times as many as Danielle sold, the amount sold by Brett is 3×d = 3d ..... 3
The number of tickets that the 3 students sold altogether can be gotten by adding equation 1, 2 and 3 together as shown;
d+(d+4)+3d
Collect like terms
= d+d+3d+4
= 2d+3d+4
= 5d+4
Hence the number of tickets that the 3 students sold altogether is represented as 5d+4
Answer:
5d+4

Dilate the figure below with a scale factor of 1.5 centered at the origin and then rotate the figure 90° clockwise about the origin.
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.

What is LN equal to?
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
