Answer:
Width = 11 yards
Length = 9 yards
Step-by-step explanation:
Area = length * width length = x width = w
Area = 99
width = x + 2
length = x
99 = (x) (x+2)
99 = x^2 + 2x
x = 9, or -11
Since we are talking about length we know x can't be -11, so we can rule that answer out.
We now know x = 9, so the length is 9 yards, now we only need to plug in 9 as x in the width equation.
w = 9 + 2
w = 11
The width is 11 yards and the length is 9 yards.

6. Gloves R’ Us was having a great day at their warehouse. Before lunch the store had sold a total of 82 pairs of gloves, and sales were brisk. At the end of the day, Dan, the owner, realized he just had the biggest day in Gloves R’ Us history with a total of 127 pairs of gloves sold. As he was heading back to restock for the next day, he asked his new employee, Mittsy, how many of each (cloth and rubber) they had sold. Poor Mittsy, being new, did not know that she was supposed to keep them separate. All she knew was that the rubber gloves were $8.95 each, the cloth gloves were $6.95 each, and the sales for the day totaled $1070.65. Help Mittsy keep her job by finding out how many of each type of glove was sold so Dan, the glove man, can restock.
Answer:
Step-by-step explanation:
c is the number of cloth gloves sold.
r is the number of cloth gloves sold.
c + r =127
c = 127 - r
6.95c + 8.95r = 1070.65
6.95(127 - r) + 8.95r = 1070.65
882.65 + 2r = 1070.65
r = 94
c = 33
Find the missing height of the solid figure
9514 1404 393
Answer:
5 in
Step-by-step explanation:
The figure's angles are presumed to be right angles everywhere, so the left-side vertical dimension is equal to the right-side vertical dimension.
The right side is marked as 15 inches.
The left side has two vertical segments, one of which is 10 inches. Since the total left-side height must be the same as the right-side height, we have ...
10 in + ? = 15 in
? = 5 in . . . . . . subtract 10 in
The missing height is 5 inches.
Solve the equation and check.
37x + 16 = 6(6x + 6)
Select the correct choice below and, if necessary, fill in the answer box to complete your choice.
O A. The solution is
(Simplify your answer.)
B. The solution is all real numbers.
OC. There is no solution.
Answer:
x = 20.
Step-by-step explanation:
37x + 16 = 6(6x + 6)
Distribute.
37x + 16 = 36x + 36
Subtract 36x from both sides.
x + 16 = 36
Subtract 16 from both sides.
x = 20.
The solution is 20.
Proof
37x + 16 = 6(6x + 6)
37(20) + 16 = 6(6(20) + 6)
740 + 16 = 6(120 + 6)
756 = 6(126)
756 = 756.
On Thursday it snowed 3 ½ inches in 4 hours. On Friday it snowed 8 inches in 9 hours. On which day was it snowing faster?
Answer:
Friday
Step-by-step explanation:
Thursday 7/2 ÷ 4 = 7/8 inches an hour (.875)
Friday 8 ÷ 9 = 8/9 inches an hour (.888)
Friday it was snowing faster
Answer:
Friday
if Thursday snowed 3½ inch 4 hours
then for Friday
9 ÷ 8 = 1.125 inches for one hour
1.125 × 4 = 4.5 inches for 4 hours
1.25 inches more than Thursday. So, the answer is Friday ^^

Find the perimeter RST. Round answer to the nearest tenth. Show all the work !!!
Given:
The figure of a triangle RST on a coordinate plane.
To find:
The perimeter of the triangle RST.
Solution:
From the given graph it is clear that the vertices of the given triangle are R(-2,7), S(-5,1) and T(-7,-5).
Distance formula:
[tex]D=\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}[/tex]
Using the distance formula, we get
[tex]RS=\sqrt{\left(-5-\left(-2\right)\right)^2+\left(1-7\right)^2}[/tex]
[tex]RS=\sqrt{\left(-5+2\right)^2+\left(1-7\right)^2}[/tex]
[tex]RS=\sqrt{\left(-3\right)^2+\left(-6\right)^2}[/tex]
on further simplification, we get
[tex]RS=\sqrt{9+36}[/tex]
[tex]RS=\sqrt{45}[/tex]
[tex]RS=3\sqrt{5}[/tex]
Similarly,
[tex]ST=\sqrt{\left(-7-\left(-5\right)\right)^2+\left(-5-1\right)^2}[/tex]
[tex]ST=2\sqrt{10}[/tex]
[tex]RT=\sqrt{\left(-7-\left(-2\right)\right)^2+\left(-5-7\right)^2}[/tex]
[tex]RT=13[/tex]
Now, the perimeter of the triangle RST is
[tex]Perimeter=RS+ST+RT[/tex]
[tex]Perimeter=3\sqrt{5}+2\sqrt{10}+13[/tex]
[tex]Perimeter=26.032759[/tex]
[tex]Perimeter\approx 26.0[/tex]
Therefore, the perimeter of the triangle RST is 26.0 units.

If a triangle is rotated about the y-axis as shown below, what three-dimensional polyhedral would be formed?
An image of a right triangle centered at the origin is shown with an arrow showing motion about the y axis.
(1 point)
Triangular prism
Cone
Cylinder
Square pyramid
Answer:
Cone
Step-by-step explanation:
I took the test and got it right :)
The triangle is rotated about the y-axis then a cone will be formed.
It is given that the triangle is rotated about the y-axis as shown in the picture.
It is required to find what three-dimensional polyhedral would be formed.
What is the triangle?The triangle can be defined as a three-sided polygon in geometry and it consists of three vertices and three edges. The sum of all the angles inside the triangle is 180°.
We have an image of a right triangle centered at the origin in the picture, if we rotate it about the y-axis we will get a cone because the side which is at the y-axis will be fixed and the base of the triangle will move about the y-axis which will make a circular shape similarly the other side(hypotenuse) will also rotate about the y-axis which will create an outer surface for the cone.
Thus, the triangle is rotated about the y-axis then a cone will be formed.

given the following sequences : -17 -25 -33 -41... write an explicit formula and find the 28th term in this sequence
Answer:
a(n) = -8n -9
a(28) = -233
Step-by-step explanation:
a(n) = a(1) + (n - 1)d
n is the nth term, a(1) is the first term, d is the common difference.
*d = -25 - (-17) = -8
a(n) = -17 + (n - 1)(-8)
= -17 + (-8n + 8)
= -17 - 8n + 8
= -8n - 9
For the 28th term
a(28) = -8(28) - 9
= -224 - 9
= -233

Given point P moving along a curve y = x²-1 and point Q moving along a line y = x-3. Find the coordinate of point Q and distance between P and Q that makes the distance between two points have minimum value. Show your work, thank you!
Answer:
Part A
The coordinates of point Q that makes the distance between the two points have minimum value is (9/8, -15/8)
Part B
The distance between P and Q at the closest point is approximately 1.287 units
Step-by-step explanation:
From the details given in the question, we have;
The curve along which point P is moving is, y = x² - 1
The (straight) line along which point Q is moving is, y = x - 3
The domain of the path of point P = All real numbers
The range of the path of point P = -1 < x ≤ ∞
The domain of the path of point Q = All real numbers
The range of the path of point Q = All real numbers
From the graph of the functions created with Microsoft Excel, we have that from point (0, 0) and moving to the positive x-axis, the slope of the path of P increases from 0 to ∞, while the slope of the path Q is constant and equal to 1
Given that the path of P is convex relative to the path of P, the two paths will be closest when they have equal slopes
Therefore at the closest point, for the path of point P, we have;
d(x² - 1)/dx = 1 (the slope of the path of point Q)
2·x = 1
∴ x = 1/2 on the path of point P at the closest point the path of point P to the path of point Q
∴ y = x² - 1 = (1/2)² - 1 = -3/4
y = -3/4
Given that two paths are parallel at the closest point, distance between the two paths is the perpendicular distance from the line y = x - 3 to the point (1/2, (-3/4)), which is given as follows;
∴ The slope of the line representing the perpendicular distance between the two paths = -1
Therefore, the equation of the line in point and slope form is given as follows;
y - (-3/4) = -1 × (x - 1/2)
y = -x + 1/2 - 3/4 = -x - 1/4
y = -x - 1/4
At the coordinates of point Q that makes the distance between the two points have minimum value, we have;
-x - 1/4 = x - 3
∴ 2·x = 3 - 3/4 = 2 1/4 = 9/4
x = 9/8
y = x - 3 = 9/8 - 3 = -15/8
Therefore, the coordinates of point Q that makes the distance between the two points have minimum value = (9/8, -15/8)
Part B
The formula for the length between two points is
[tex]l =\sqrt{\left (y_{2}-y_{1} \right )^{2}+\left (x_{2}-x_{1} \right )^{2}}[/tex]
The distance, d, between P and Q at the closest point is given as follows;
d = √(((9/8) - (1/2))² + ((-15/8) - (-3/4))²) = √(53/32) ≈ 1.287
The distance between P and Q at the closest point, d ≈ 1.287
