Answer:
400
Step-by-step explanation:
25 times the length is 1000 m.
Let length = L
25L = 1000
L = 40
10 times the perimeter is 1000 m.
Let the perimeter = P
10P = 1000
P = 100
perimeter = 2L + 2W
2(40) + 2W = 100
80 + 2W = 100
2W = 20
W = 10
The length is 40 m, and the width is 10 m.
A = LW
A = 40 m * 10 m
A = 400 m^2

Patio sets consisting of couches, umbrellas, and a firepit table are sold at a local furniture store, A set with 2 couches, an umbrella and a table are sold for $1875. A set with one couch and a table are sold for $1075. A set with 2 couches and an umbrella are sold for $1275What is the price of the table?
Answer:
[tex]T = 600[/tex]
Step-by-step explanation:
Represent the table with T, couch with C an umbrella with U
We have the following:
[tex]2C + U + T = 1875[/tex]
[tex]C + T = 1075[/tex]
[tex]2C + U = 1275[/tex]
Required
Determine the cost of a table
Make T [tex]the\ subject\[/tex] [tex]in\ the[/tex] first equation
[tex]T = 1875 - (2C + U)[/tex]
In the third equation, we have that: [tex]2C + U = 1275[/tex]
By substituting 1275 for 2C + U
[tex]T = 1875 - (2C + U)[/tex] becomes
[tex]T = 1875 - 1275[/tex]
[tex]T = 600[/tex]
Hence, a table costs $600
You are downsizing. Your new residence will have much less closet space than does your current home. You have 12 pair of long pants, 6 pair of short pants and 17 t-shirts. You plan to give some away.
a. In how many ways can a random selection of 9 pair of long pants, 4 pair of short pants and 13 t-shirts be arranged?
b. You randomly select 25 of the items of clothing to give away. What is the probability you select 10 pair of long pants, 3 pair of short pants and 12 t-shirts?
Answer:
a) there are 7,854,000 number of ways the random selections can be arranged
b) the required probability is 0.0445
Step-by-step explanation:
Given that;
you have 12 pair of long pants, 6 pair of short pant and 17 t-shirt which in total;
Total = 12 + 6 + 17 = 35
a) number of ways a random selection of 9 pair of long pants, 4 pair of short pants and 13 t-shirts can be arranged;
⇒ [ 12 × [ 6 × [ 17
9 ] 4 ] 13 ]
= (12! / (9! 3!)) (6! / (4! 2!)) (17! / (13! 4!))
= (220) (15) (2380)
= 7,854,000
Therefore there are 7,854,000 number of ways the random selections can be arranged
b)
Number of ways of selecting 25 item from 35 items;
⇒ [ 35
25 ]
=
(35! / (25! 10!) = 183.579,396
now number of ways to select 10 pair of long pants, 3 pairs of short pantts and 12 t-shirt;
⇒ [ 12 × [ 6 × [ 17
10 ] 3 ] 12 ]
= (12! / (10! 2!)) (6! / (3! 3!)) (17! / (12! 5!))
= (66) (20) (6188)
= 8,168,160
So, Required probability = 8,168,160 / 183,579,396
= 0.0445
So the required probability is 0.0445

19 more than 9 times a number is less than or equal to 163. Which of the following represents the solution set of this problem?
Answer:
x ≤ 6
Step-by-step explanation:
Let the unknown number be x;
9 times the number is expressed as 9x
9 more than 9 times a number is expressed as 9x + 9
9 more than 9 times a number is less than or equal to 163 is then expressed as;
9x + 9≤ 63
≤ is the less than or equal to sign
Find the solution;
9x ≤ 63 - 9
9x≤54
x ≤ 54/9
x≤ 6
Hence the required solution is x ≤ 6

In the picture lines AB and CD are parallel. Find the measures of the following angles. Explain your reasoning.
Answer/Step-by-step explanation:
1. <ABC and <BCD are alternate interior angles. Alternate interior angles are equal, therefore, since m<ABC = 38°, then m<BCD = 38°
2. m<ECF = m<BCD (corresponding angles)
m<ECF = 38° (substitution)
3. m<DCF + m<ECF = 180° (linear pair)
m<DCF + 38° = 180° (substitution)
m<DCF = 180° - 38° (Subtraction property of equality)
m<DCF = 142°

2×0=0
22+2=24÷8=3
Answer:
1. 0
2. 549662557860
Step-by-step explanation:
Well 2+2+9+9+0+2x0+2 is 0 because anything time 0 is 0 so then you do 0 divided by 8 which is 0. Then 234898529 x 2340 is 549662557860 is you add the commas then... 234,898,529 x 2,340 is 549,662,557,860

Use the transformations on the function f(x) = x| to select the correct graph of
Answer: A
Step-by-step explanation:
The correct graph to the parent function after the transformation is shown in the picture.
What is a function?
It is defined as a special type of relationship, and they have a predefined domain and range according to the function every value in the domain is related to exactly one value in the range.
We have a parent function:
y = |x|
Applying first transformation:
Multiply by 1/3 the graph of the function will stretch
[tex]\rm y = \dfrac{1}{3} |x|[/tex]
Second transformation:
Add 1 to the function, the graph will shift upside by 1 units.
[tex]\rm y = \dfrac{1}{3} |x|+1[/tex]
Thus, the correct graph to the parent function after the transformation is shown in the picture.

I need to find the identity of this equation for pre calc
Expand the left side using the angle sum identity for sine:
sin(x + π/2) = sin(x) cos(π/2) + cos(x) sin(π/2)
cos(π/2) = 0 and sin(π/2) = 1, so the right side reduces to
sin(x + π/2) = cos(x)

Joe’s garden is the shape of a hexagon. The measures of 5 of the angles are: 160°, 90°, 60°, 160°, and 80°. What is the measure of the remaining angle? *
Answer:
1800000000000000000
The solution is 170°, is the measure of the remaining angle.
What is addition?Addition is a way of combining things and counting them together as one large group. ... Addition in math is a process of combining two or more numbers.
here, we have,
given that,
The measures of 5 of the interior angles of a hexagon are: 160°, 90°, 60°, 160°, and 80°.
so, we have,
Sum of all the six interior angles of a hexagon is 720°
now, we get,
The sum of 5 interior angles is = 160°+ 90°+ 60°+ 160°+ 80° degrees
= 550
The missing 6th angle is = 720° - 550degrees
=170
So the remaining angle of hexagon is 170 degrees.
Therefore, the answer is 170°.

THE ANSWERS ARE WRONG. I need help finding the right answers for 30 pts. I will post an additional question after this for 30 points aswell.
Answer:
∠D = 60
∠E = 99; x = 4
x = 32
Step-by-step explanation:
First things first, the sum of angles in a quadrilateral is 360°.
∠D + 120 + 95 + 85 = 360
∠D = 360 - 120 - 95 - 85
∠D = 60
∠E + 86 + 100 + 75 = 360
∠E = 360 - 86 - 100 - 75
∠E = 99
24x + 3 = 99
24x = 99 - 3
= 96
x = 96 ÷ 24
x = 4
89 + 5x - 8 + 51 + 3x + 4 = 360
7x + 136 = 360
7x = 360 - 136
= 224
x = 224 ÷ 7
x = 32

at what x coordinate would a line whose equation is y=2x-3 intersect a perpendicular line whose y intercept is 17
Answer:
Step-by-step explanation:hj
Using linear function concepts, it is found that these lines intersect at x = 8.
The equation of a line is given by:
[tex]y = mx + b[/tex]
In which:
m is the slope, which is the rate of change.b is the y-intercept, which is the value of y when x = 0.If two lines are perpendicular, the multiplication of their slopes is -1.Line perpendicular to y = 2x - 3.
Multiplication of the slopes is -1, thus:
[tex]2m = -1[/tex]
[tex]m = -\frac{1}{2}[/tex]
y-intercept of 17 means that b = 17, thus, the equation of the line is:
[tex]y_p = -\frac{1}{2}x + 17[/tex]
They intersect at the value of x for which:
[tex]y = y_p[/tex]
Then
[tex]2x - 3 = -\frac{1}{2}x + 17[/tex]
[tex]2x + \frac{1}{2}x = 20[/tex]
[tex]\frac{5x}{2} = 20[/tex]
[tex]5x = 40[/tex]
[tex]x = \frac{40}{5}[/tex]
[tex]x = 8[/tex]
