An empty lot is being covered into a park with a playground area. The shape of the playground is shown below. This area will be covered with recycled rubber chips. Find the area of the figure given to determine how many square feet of rubber chips will be needed.
**SEE ATTATCHED DIAGRAM***
To solve for the area, find the area of an entire theoretical parallelogram. Then subtract the difference (the small triangle added).
Area = 1020 centimeters squared
If you need the answer in square feet, you have to convert.
(1 cm)^2 = (0.3937008 inches)^2
1 cm ^2 ≅0.155 in ^ 2 (or square inches)
A = 1020 * 0.155 ≅ 158.1 square inches
1 square inch = 0.006944444 square feet
158.1 square inches ≅ 1.097 square feet
Given that the measure of ∠x is 73°, and the measure of ∠y is 40°, find the measure of ∠z.
Hi,
In a triangle, all angles must add up to 180*.
73 + 40 = 113
180 - 113 = 67
Thus, the measure of Z is equal to 67

A certain television is advertised as a 45-inch TV (the diagonal length). If the width of the TV is 36 inches, how many inches tall is the TV?
The TV is 27 inches tall.
Step-by-step explanation:
Given,
The diagonal length of the TV = 45 in
The width of the TV = 36 in
To find the length the the TV.
Formula
By Pythagoras theorem,
h²=l²+b², where h be hypotenuse, b be base and l be height.
Now,
Putting, h=45, b= 36 we get,
45²=l²+36²
or, l²= 45²-36²
or, l²= 729
or, l = √729
or, l = 27
Hence,
The TV is 27 in tall.

{40, 54, 22, 30, 55, 13, 33}
A) 32
B) 33
C) 40
D) 42
Step-by-step explanation:
Arranging in ascending order, we get
13 , 22 , 30 , 33 , 40 , 54 , 55
no of data (N) = 7
Now Position of Median
= {(N +1 ) / 2}th item
= {(7+1) / 2 } that item
= 4 that item
So now exact median = 33
Answer:
The answer is 33
Step-by-step explanation:
By arranging the numbers in order of smallest to largest you get: ----------------> 13, 22, 30, 33, 40, 54, 55. Cross off a number from each side until you get one or two left in the middle. Cross out 13 and 55 then 22 and 54 then 30 and 40. Now you have 33 left in the middle, that is your median
Terry is going to make some concrete mix. He needs to mix
cement, sand and gravel in the ratio 2 . 3 : 5 by weight. He
estimates he needs to make 220 kg of concrete mix.
Terry has:
• 50 kg of cement
• 90 kg of sand
• 100 kg of gravel
Does Terry have enough cement, sand and gravel to make the
concrete mix?
Answer:
No
Step-by-step explanation:
Sum the parts of the ratio, 2 + 3 + 5 = 10 parts
Divide 220 Kg by 10 to find the value of one part of the ratio.
220 Kg ÷ 10 = 22 Kg ← value of 1 part of the ratio, thus
2 parts = 2 × 22 = 44 Kg ← quantity of cement needed
3 parts = 3 × 22 = 66 Kg ← quantity of sand needed
5 parts = 5 × 22 = 110 Kg ← quantity of gravel needed
He has the required amounts of cement and sand but not of gravel.
Thus he cannot mix the concrete
Terry requires 44 kg of cement, 66 kg of sand, and 110 kg of gravel for the concrete mix. He has enough cement and sand but is short of gravel by 10 kg, so he cannot make the complete mix with the materials he currently has.
Explanation:First, we calculate the total parts of the mix by adding the ratio numbers: 2 (cement) + 3 (sand) + 5 (gravel) = 10 parts in total. Next, we find out how much each part weighs: 220 kg ÷ 10 parts = 22 kg per part. Then we multiply the number of parts for each material by the weight per part: Cement needed = 2 parts × 22 kg/part = 44 kg, Sand needed = 3 parts × 22 kg/part = 66 kg, Gravel needed = 5 parts × 22 kg/part = 110 kg. Now, let's compare these requirements with what Terry has:
Cement: needs 44 kg, has 50 kg — enoughSand: needs 66 kg, has 90 kg — enoughGravel: needs 110 kg, has 100 kg — not enoughIn conclusion, Terry does have enough cement and sand, but he does not have enough gravel for the mix.

an arc subtends a central angle measuring 2pi/3 radians. what fraction of the circumference is this arc?
Answer:
1/3
Step-by-step explanation:
The fraction of the circumference that the arc subtends is 1/3.
Explanation:An arc that subtends a central angle measuring 2π/3 radians is a fraction of the circumference. To find the fraction, we can use the formula:
Fraction of circumference = (angle/2π) x 1
Substituting the given angle into the formula, we have:
Fraction of circumference = (2π/3 /2π) x 1
Simplifying the expression, we get:

Find the volume of the composite figure. Round to the nearest tenth. The base of each pyramid is a square with a side length of 5 inches and each pyramid has a height of 9 inches.
Answer:
[tex]75[/tex] cubic inches
Step-by-step explanation:
Given:
The base of each pyramid is a square with a side length of 5 inches
Height of of pyramid is 9 inches.
To find: volume of the pyramid
Solution:
As the base of each pyramid is a square with a side length of 5 inches,
length of the pyramid (l) = base of the pyramid (b) = 5 inches
Height of of pyramid (h) = 9 inches
Volume of the pyramid [tex](V)=\frac{lbh}{3}[/tex]
On putting values of l, b and h, we get
[tex]V=\frac{5\times 5\times 9}{3}=75[/tex] cubic inches

The table shows two x-intercepts and it changes from increasing to decreasing.
The correct option is D.
Sebastian use in his deduction the table shows two x-intercepts and it changes from increasing to decreasing.
CONCULSION-The curve is definitely not logarithmic because it has two x-intercepts.The curve will cut the x-axis at two points and hence, it will have two x-intercepts.There is no sign of any y-intercept based on the data available in the table.

Sebastian used the information 'The table shows two x-intercepts and it changes from increasing to decreasing' for his deduction. This could suggest that he might be dealing with a quadratics or an inverted expressive function.
Explanation:Based on the choices provided, it appears that Sebastian used the information that 'The table shows two x-intercepts and it changes from increasing to decreasing' in his deduction. An x-intercept in a function table happens where the y-value equals zero. Two x-intercepts imply that there are two points where the function crosses the x-axis. A function's pattern shifting from an increasing pattern to a decreasing pattern is indicative of a maximum point. This suggests that Sebastian may be working with a quadratics or an inverted expressional function.

A planet follows an elliptical path described by 256 x squared plus 16 y squared equals 4096.256x2+16y2=4096. A comet follows the parabolic path y equals x squared minus 16.y=x2−16. Where might the comet intersect the orbiting planet?
Final answer:
To find the intersection points of the comet and the planet's orbits, we need to solve the system of equations formed by their respective path equations.
Explanation:
To find where the comet might intersect the orbiting planet, we need to find the common points between the equation of the planet's elliptical path and the equation of the comet's parabolic path.
By substituting the expression for y in the equation of the planet into the equation of the comet, we get 256x^2 + 16(x^2 - 16) = 4096.
Simplifying this equation and solving for x will give us the x-coordinates where the comet may intersect the planet's orbit. Substituting these x-values back into either the planet's or comet's equation will give us the corresponding y-coordinates.

While at a bakery, Chad decides to purchase some cupcakes and brownies to share with his friends. He can spend no more than $13, and the bakery charges $3 for a cupcake and $2 for a brownie. Select the inequality in standard form that describes this situation. Use the given numbers and the following variables.
x = the number of cupcakes
y = the number of brownies
Answer:
13 divided by 6
Step-by-step explanation:
Final answer:
The situation where Chad is buying cupcakes and brownies with a budget of $13 is represented by the inequality 3x + 2y ≤ 13, where x is the number of cupcakes and y is the number of brownies.
Explanation:
To express Chad's purchasing situation at the bakery within his budget constraint in inequality form, we need to consider the cost per cupcake and brownie and how many of each he can buy without exceeding his budget of $13. Given that a cupcake costs $3 and a brownie costs $2, the inequality in standard form will reflect the price of each item multiplied by the quantity purchased.
The inequality representing this situation is 3x + 2y ≤ 13, where 'x' is the number of cupcakes and 'y' is the number of brownies. This inequality means that the total cost of cupcakes and brownies combined must not exceed $13, which corresponds to Chad's budget constraint.
