Find the area of the sector:
A=
yd? (Round to one decimal place)
210°
16 yd
Answer:
469.1 yd²
Step-by-step explanation:
The area (A) of the sector is calculated as
A = area of circle × fraction of circle
= πr² × [tex]\frac{210}{360}[/tex]
= π × 16² × [tex]\frac{21}{36}[/tex]
= 256π × [tex]\frac{7}{12}[/tex]
≈ 469.1 yd² ( to 1 dec. place )

b) Solve G(x) = 0.
2) In the adjacent figure ABCD is a square:
a) Express the area of the square and the area
of triangle AEB in terms of x.
b) Calculate x so that the area of the square is equal
to 6 times the area of triangle AEB.
Answer:
In bold.
Step-by-step explanation:
a. (x+5)^2 – 3x(x+5) x+5 is common
= (x + 5)(x + 5 - 3x)
= (x + 5)(5 - 2x)
b. (x + 5)(5 - 2x) = 0
x = -5, 2.5.
2a. Area of the square = (x + 5)^2
Area of triangle AEB
= 1/2 * base * height
I am assuming that H is the centre of AB , so
Area = x*x
= x^2.
2b
6x^2 = (x + 5)^2
6x^2 = x^2 + 10x + 25
5x^2 - 10x - 25 = 0
x^2 - 2x - 5 = 0
x = [-(-2) +/- sqrt(2^2 - 4*1*-5)] / 2
x = -1.45, 3.45.

A rhombus, which is a quadrilateral with 4 equal sides, is plotted on the coordinate plane. The coordinates of the vertices are: (−1,0), (4,0), (2,4), and (7,4). How long is each side of the rhombus?
Answer:
Each side of the Rhombus is 5 units
Step-by-step explanation:
Since the sides of a rhombus area all equal in length;
Then, the length of a side is enough to get the lengths of the other sides
Mathematically, finding the distance between two points out of what we are given will be enough to get the measure of one of the side of the rhombus
We apply the distance formula appropriately to get the distance between the side of the Rhombus
D = √(x2-x1)^2 + (y2-y1)^2
let us use the points (-1,0) and (4,0)
D = √(4 + 1)^2 + (0-0)^2
D = √25
D = 5
Solve the system of linear equations by substitution x-y=2 x+2y=5
Answer:
x = 3
y = 1
Step-by-step explanation:
x - y = 2 ---------------(I)
x + 2y= 5 ----------------(II)
x - y = 2
x = 2 + y _________(III)
Substitute x = 2 + y in equation (II)
2 + y + 2y = 5 {combine like terms}
2 + 3y = 5
3y = 5 -2
3y = 3
y = 3/3
y = 1
Substitute y = 1 in equation (III)
x = 2 + 1
x = 3

Answer:
C = 100 + 40n
The independent variable is n (number of months) and the dependent variable is C ( total cost)
Step-by-step explanation:
Let the total cost of the fitness center = C
Given fixed cost = $100
given cost per month = $40
let number of month = n
The total cost of the fitness center in a given 'n' month is calculated as;
C = 100 + 40n
From the above equation;
the independent variable is n (number of months) and
the dependent variable is C ( total cost)
C = 100 + 40n The independent variable is n (number of months) and the dependent variable is C ( total cost)
The probability that event A occurs is 0.4, and the probability that events A and B both occur is 0.25. If the probability that either event A or event B occurs is 0.6, what is the probability that event B will occur
Answer:
The probability that event B will occur is 0.45
Step-by-step explanation:
Given;
probability that event A occurs, P(A) = 0.4
the probability that events A and B both occur, P(A ∩ B) = 0.25
the probability that either event A or event B occurs, P(A ∪ B) = 0.6
To determine the probability that event B will occur, we use probability addition rule;
P(A) + P(B) = P(A ∩ B) + P(A ∪ B)
0.4 + P(B) = 0.25 + 0.6
0.4 + P(B) = 0.85
P(B) = 0.85 - 0.4
P(B) = 0.45
Therefore, the probability that event B will occur is 0.45
The sum of three numbers is 76. The third number is eight less than the first. The second number is two times the third. What are the numbers?
Step-by-step explanation:
Read the poem. excerpt from “Spring” by Christina Rossetti Frost-locked all the winter, Seeds, and roots, and stones of fruits, What shall make their sap ascend That they may put forth shoots? Tips of tender green, Leaf, or blade, or sheath; Telling of the hidden life That breaks forth underneath, Life nursed in its grave by Death. Which line from the poem contributes most to a hopeful tone? "Telling of the hidden life" "Frost-locked all the winter," "Life nursed in its grave by Death." "What shall make their sap ascend"
The numbers are 25, 34, and 17.
Let x be the first number, y be the second number, and z be the third number. We know that x + y + z = 76, z = x - 8, and y = 2z.
Substituting the second and third equations into the first equation, we get x + 2(x - 8) + (x - 8) = 76.
Simplifying the right side of the equation, we get 4x - 24 = 76.
Adding 24 to both sides of the equation, we get 4x = 100.
Dividing both sides of the equation by 4, we get x = 25.
Substituting x = 25 into the equation z = x - 8, we get z = 25 - 8 = 17.
Substituting x = 25 and z = 17 into the equation y = 2z, we get y = 2 * 17 = 34.
Therefore, the numbers are 25, 34, and 17.

A chemist is using 353 milliliters of a solution of acid and water. If 14.7 of the solution is acid, how many milliliters of acid are there? Round your answer to the nearest tenth
Answer:
The amount of Acid in a solution = 51.9 millimeters
Step-by-step explanation:
Given that the total amount of solution of acid and water = 353 milliliters
Acid percentage = 14.7%
Thus, in order to determine the amount of acid, all we need is to multiply 353 with 14.7% or 0.147.i.e
Amount of Acid = 14.7% of 353
= 0.147 × 353
= 51.9 millimeters
Therefore, the amount of Acid in a solution = 51.9 millimeters

The equation is y =
Please help very urgent! :)
Answer:
y = - 0.05x - 1.9
Step-by-step explanation:
The equation of a line in slope- intercept form is
y = mx + b ( m is the slope and b the y- intercept )
y = 20x ← is in slope- intercept form
with slope m = 20
Given a line with slope m then the slope of a line perpendicular to it is
[tex]m_{perpendicular}[/tex] = - [tex]\frac{1}{m}[/tex] = - [tex]\frac{1}{20}[/tex] = - 0.05 , thus
y = - 0.05x + b ← is the partial equation
To find b substitute (2, - 2) into the partial equation
- 2 = - 0.1 + b ⇒ b = - 2 + 0.1 = - 1.9
y = - 0.05x - 1.9 ← equation of perpendicular line

27/3=9....Salma used a photocopier to dilate the design for a monorail track system. The figure shows the design and its photocopy: Two irregular quadrilaterals ABCD and EFGH are drawn. EFGH is the photocopy of design ABCD. AB measures 15 meters, DC measures 17 meters. No dimensions are shown on EFGH. The ratio of AD:EH is 1:2. What is the length, in meters, of side GH on the photocopied image? 15 17 30 34
Answer:
The answer is 34
Step-by-step explanation:
The ratio of AD:EH is 1:2, so therefore the other line segments have the same ratio. Using this logic, we see that DC is equal to 17 m, and we need to find GH. All we do now is double the measurement of DC since the ratio of the two shapes is 1:2.
Therefore, 17 * 2 = 34

34

a crane lifts a pallet of concrete blocks 7 ft from the back of the truck . the truck driver away and the crane lowers the pallet 12ft what is the final position of the pallet relative to where it started in the back of the truck?
Answer:
4 ft down as per the image attached.
5 ft down as per the question statement.
Step-by-step explanation:
Given that:
A Pallet of concrete blocks is at the back of a truck.
The pallet is lifted by the crane to a height of 8 ft (as per image attached ) or 7 ft (as per question statement) and then the truck moves forward.
Now, the pallet is lowered down to a distance of 12 ft.
To find:
The final position of the pallet relative to the position from the back of the truck?
Solution:
If we closely look at the figure attached, it can be interpreted that the pallet is taken 8 feet above and then 12 feet down.
Therefore, if we subtract 8 feet from 12 feet, we will have our answer.
So, the position of the pallet with respect to its position in the truck is =
12 ft - 8 ft = 4 ft down.
If we consider the question statement:
12 ft - 7 ft = 5 ft down
Answer:
The final position is 5feet below the back of the truck
