Desmond plays 30 minutes of soccer each day. How many seconds of soccer does Desmond play in 6 days?
Answers
Answer:Desmond will play for 10800 seconds in 6 days
Step-by-step explanation:
In a Day Desmond plays soccer = 30 minutes
In 6 days, he will play = 6 x 30 = 180 minutes
Changing 180 minutes to seconds
we know that 60 second s= 1 minutes
Therefore ?? seconds = 180 minutes
180 x 60 =10800 seconds
Use the drawing and the provided ruler. Each centimeter in the drawing represents 5 feet. The perimeter of the blue perennial bed is ___ feet. The perimeter of the green perennial bed is ___ feet.
Answers
Answer:
Blue bed is 50 feet
Green bed is 35 feet
Step-by-step explanation: If you use a ruler it is 3 centimeters long ways and it is 2 centimeters sideways. 3+3= 6 and 2+2=4 which is 10 added together. If every centimeter represents 5 feet then 5 x 10= 50. Repeat for green and there's your answer :)

What is the inequality that represents the graph shown?
Answers
Given:
The graph of an inequality.
To find:
The inequality that represents the graph shown.
Solution:
From the given graph it is clear that the boundary line passes through the points (0,-1) and (2,0). So, the equation of boundary line is
[tex]y-y_1=\dfrac{y_2-y_1}{x_2-x_1}(x-x_1)[/tex]
[tex]y-(-1)=\dfrac{0-(-1)}{2-0}(x-0)[/tex]
[tex]y+1=\dfrac{1}{2}x[/tex]
[tex]y=\dfrac{1}{2}x-1[/tex]
The boundary line is a dashed line and the shaded portion is below the boundary line so the sign of inequality must be <.
[tex]y<\dfrac{1}{2}x-1[/tex]
Therefore, the required inequality is [tex]y<\dfrac{1}{2}x-1[/tex].

============================================================
Work Shown:
The triangle has the given angles A = 45 and B = 89
Let's find angle C
A+B+C = 180
C = 180-A-B
C = 180-45-89
C = 46
----------------
Segment BA, or side c, is opposite angle C
Segment AC, or side b, is opposite angle B
So we have this known info:
angle B = 89side b = 15angle C = 46Apply the law of sines to find c. Make sure your calculator is in degree mode.
sin(B)/b = sin(C)/c
sin(89)/15 = sin(46)/c
c*sin(89) = 15*sin(46)
c = 15*sin(46)/sin(89)
c = 10.7917406394501
c = 10.8

Step-by-step explanation:
[tex]3(x - y)^{2} - 2(x - y)[/tex]
Lets take [tex](x - y)[/tex] common from the expression.
[tex]=> (x - y) [3(x - y) - 2][/tex]
The factors of the expression 3(x - y)² - 2(x - y) will be (3x - 3y - 2) and (x - y).
What is factorization?It is a method for dividing a polynomial into pieces that will be multiplied together. At this moment, the polynomial's value will be zero.
The definition of simplicity is making something simpler to achieve or grasp while also making it a little less difficult.
The expression is given below.
⇒ 3(x - y)² - 2(x - y)
Simplify the expression, then we have
⇒ 3(x - y)² - 2(x - y)
⇒ (x - y)[3(x - y) - 2]
⇒ (x - y)(3x - 3y - 2)
The factors of the expression 3(x - y)² - 2(x - y) will be (3x - 3y - 2) and (x - y).

The length of a rectangle is 4 centimeters longer than the width of the rectangle. The perimeter of the rectangle is 88 centimeters. What us the area of the rectangle, in square centimeters?
Answers
Answer:
Perimeter P = 2L + 2W = 88
We also have L = W + 4
Now substitute this into the first equation and get
2(W + 4) + 2W = 88
2W + 8 + 2W = 88
4W + 8 = 88
4W = 80
W = 20 cm
L = 24 cm
You have been told to make 144 two ounce chocolate chip cookies for a banquet . The recipe yields three pounds of cookie . By what factor would you need to increase the recipe
Answers
Answer: 6
Step-by-step explanation:
You have been told to make 144 two ounce chocolate chip cookies so the total weight of those cookies is:
= 144 * 2
= 288 ounces
A pound is equivalent to 16 ounces.
The recipe yields 3 pounds of cookies which is:
= 3 * 16
= 48 ounces
For the recipe to make 288 ounces, you need to scale up by:
= 288 / 48
= 6
