a rectangle of side 48cm by 60cm is divided into squares of side x cm.find the greatest value of x and find the area of the area.
Answer:
greatest value of X = 12
Area of square = 144 cm²
Step-by-step explanation:
The greatest value of X will be the highest common factor of 48 and 60 since we are told that the rectangle is divided into squares.
Factors of 48: 1, 2, 3, 4, 6, 8, 12, 16, 24, 48
Factors of 60: 1, 2, 3, 4, 5, 6, 10, 12, 15, 20, 30, 60
The highest common factor between both factors of 48 and 60 is 12.
Thus,
greatest value of X = 12
Area of square = 12 × 12
Area of square = 144 cm²
I need helppppppppppp
Answer:
b.)36
Step-by-step explanation:
Formula for area of a trapezoid = [tex]\frac{a+b}{2} h[/tex]
where a and b = bases and h = height
The sign has the following dimensions
Base 1 = 6ft
base 2 = 12ft
height = 4ft
Using these dimensions we plug in the values into the formula
[tex]A=\frac{6+12}{2} 4\\6+12=18\\\frac{18}{2} =9\\9*4=36[/tex]
Hence the area of Mr. Wash's sign is 36 square feet.
Answer:
b) 36 sq ft.
Step-by-step explanation:
6 x 4 = 24 (multiply to find the square after splitting it)
12 - 6 = 6 x 4 = 24 / 2 = 12 (you divide by two because it's a triangle)
24 + 12 = 36

Sarah's dad bought her a scooter that cost $89.95. He figures he can spend up to $30.05 on a helmet before he spends too much money in all. Let x represent how much money Sarah's dad wants to spend in all. Which inequality describes the problem?
Answer:
x - 89.95 ≤ 30.05= x ≤ 120
add 89.95 to both sides of the equation. Since on the right side 89.95 is already there it cancells eachother out leaving x. After adding 89.95 to 30.05 you should get an answer of 120.
The money Sarah's dad wants to spend in all if Sarah's dad bought her a scooter that costs $89.95, He can spend up to $30.05 on a helmet, which is less than or equal to $120, x ≤ 120.
What is inequality?Inequality is a relationship that compares two numbers or other mathematical expressions in an unequal way. Inequalities are the name given to certain algebraic mathematical expressions.
Given:
Sarah's dad bought her a scooter that cost $89.95,
He can spend up to $30.05 on a helmet,
Assume the x is the money Sarah's dad wants to spend in all,
Write the inequality as shown below,
x - 89.95 ≤ 30.05
Solve the inequality by adding 89.95 on both sides,
x - 89.95 + 89.95 ≤ 30.05 + 89.95
x ≤ 120

A helicopter pad has a circumference of 47.5 yards. Find the approximate diameter of the helicopter pad. Use 3.14 for π.
The approximate diameter of the helicopter pad is 15.13 yards.
We can use the formula for a circle's circumference, C = πd , where C is the circumference, d is the diameter, and π is a constant equivalent to roughly 3.14, to determine the estimated diameter of the helicopter pad.We can use the method to solve for the diameter if we know the helicopter pad's circumference to be 47.5 yards. After rearranging the equation, we get d = C/π.Thus, using the provided values as a substitute, we obtain d = 47.5/3.14 = 15.13 yards. (rounded to two decimal places).As a result, the helicopter pad's estimated diameter is 15.13 yards.

Answer:
Package 3
Step-by-step explanation:
Package 1,
No. of plates = 5
Cost = $38.75
Cost of 1 plate = [tex]\dfrac{38.75}{5}=\$7.75[/tex]
Package 2,
No. of plates = 8
Cost = $58
Cost of 1 plate = [tex]\dfrac{58}{8}=\$7.25[/tex]
Package 3,
No. of plates = 14
Cost = $94.5
Cost of 1 plate = [tex]\dfrac{94.5}{14}=\$6.75[/tex]
The cost of 1 plate in package 3 is the least. It means she should buy package 3.

A rectangular prism with a square base has a volume of 980 inches. If the height of this rectangular prism is 5 inches, what are the dimensions of its base?
Answer:
14 inches
Step-by-step explanation:
Since the rectangular prism has a square base, we know that the width and length are equal.
Using the formula for calculating the volume of a rectangular prism, we can set up an equation:
(width^2)*height = 980 cubic inches or
(width^2)*5 in. = 980 cubic inches, simplify the equation by dividing each side by 5 inches, and the result is:
width^2 = 196 sq.in., simply by taking the square root of each side of the equation, and the result is:
√width (inches) = √196 square inches = width = 14 inches
each side of the prism's base is 14 inches
Answer:
980 in

Maria had $22.45 to spend on groceries. After buying 3 bags of chips, she had $10.60 left. If each bag of chips costs the same amount, what is the price of one bag of chips
Answer:
$3.95
Step-by-step explanation:
Take the amount she has to spend and subtract the amount left ($10.60) and that will leave you with $11.85. So this is how much was spent on the 3 bags of chips. To find how much each bag cost, divide $11.85/3 bags = $3.95 per bag.
Which of the following could be the equation of the function below?
y=0.5cos(2(x-pi/2))+2 y=0.5cos(4(x+pi/2))-2 y=0.5cos(4(x+pi))+2 y=0.5cos(2(x-pi))-2
Answer:
D y=0.5cos(2(x-pi))-2
Step-by-step explanation:
The Equation of the function is y=0.5 cos (4(x+π/2))-2
The correct option is B.
As, y=a cos (b(x+c))+d
Here, y max=-1.5 and y min=-2.5
So, d=(max + min)/2
d=(-1.5+(-2.5))/2
d=(-1.5-2.5)/2
d=(-4.0)/2
d=-2.0
and, the horizontal axis is
y=-2
Then, y= a cos(b(x+c))+(-2)
y=a cos (b(x+c))-2
The amplitude (a) is
a = max-d = d- min
a=-1.5-(-2)=-2-(-2.5)
a=-1.5+2=-2+2.5
a=0.5.
We have the period is π/2
P=2π/b
π/2=2π/b
πb=4π
b=4
Now, y=0.5 cos (4(x+c))-2
Thus, the required function is y=0.5 cos (4(x+π/2))-2.

Step-by-step explanation:
Given
[tex]y\ \alpha\ \ x[/tex]
[tex]y=24; x =16[/tex]
Required
Find y when [tex]x = 50[/tex]
We have:
[tex]y\ \alpha\ \ x[/tex]
Express as equation
[tex]y = kx[/tex]
Solve for k
[tex]k = \frac{y}{x}[/tex]
When [tex]y=24; x =16[/tex]
[tex]k = \frac{24}{16}[/tex]
[tex]k = \frac{3}{2}[/tex]
When [tex]x = 50[/tex], we have:
[tex]y = kx[/tex]
[tex]y = \frac{3}{2} * 50[/tex]
[tex]y = 75[/tex]
