WRITE THE RATIO: A cookie recipe calls for 1 cup of flour to make 24 cookies. Create a proportion to show how many cups of flour are needed to make 36 cookies
Answer:
1&(1/2) or 1.5 or 3/2 cups flour needed for 36 cookies
Step-by-step explanation:
Flour : Cookie ratio (Flour needed to make particular cookie) = 1 : 24
1 cup flour make 24 cookies, so 1/2 cup floor make 12 (half) cookies.
So, 1&(1/2) or 1.5 or 3/2 cups would make 24 + 12, ie = 36 cookies
AlternativelyMultiplying numerator & denominator of fractional ratio 1 : 24 with 1.5 each
(1 x 1.5) : (24 x 1.5)
It implies 1.5 : 36 flour cookie ratio

Find the value of x. Round to the nearest tenth. The diagram is not drawn to scale.
Answer:
Cosine 24 = adjacent / hypotenuse (x)
0.91355 = 11 / hypotenuse
hypotenuse = 11 / 0.91355
hypotenuse (x) = 12.0409391933
or x = 12.04 (rounded)

A rectangle has vertices A(0, 0), B(0, 9), C(4, 9), and D(4, 0). What is the perimeter of the rectangle
Answer:
26 units
Step-by-step explanation:
A rectangle has vertices A(0, 0), B(0, 9), C(4, 9), and D(4, 0). What is the perimeter of the rectangle
We have to find the length of the sides of the rectangle using the formula below
= √(x2 - x1)² + (y2 - y1)² when given vertices (x1, y1) and (x2, y2)
For side AB
A(0, 0), B(0, 9)
= √(0 - 0)² + (9 - 0)²
= √0 + 81
= √81
= 9 units
For side BC
B(0, 9), C(4, 9)
= √(4 - 0)² + (9 - 9)²
= √4² + 0²
= √16
= 4 units
For side CD
C(4, 9), and D(4, 0)
= √(4 - 4)² + (9 - 0)²
= √0² + 9²
= √81
= 9 units
For side AD
A(0, 0), D(4, 0).
= √(4 - 0)² + (0 - 0)²
= √4² + 0
= √16
= 4 units
We can see than
AB = CD = 9 units
BC = AD = 4 units
The perimeter of a rectangle = 2(L + W)
From the above calculation
Length = 4 units
Width = 9 units
Perimeter = 2(4 + 9) units
= 2 × 13 units
= 26 units
What is the circumference of a circle with a diameter of 40 in?
Answer:
126 in²
Step-by-step explanation:
C = πd when the diameter is known. If the diameter is 40 in, then the radius is half that, or 20 in.
Then the circumference of a circle with a diameter of 40 in is
C = (40 in)π. This works out to approximately 126 in²

what is the sum of the perimeter in units of the five squares in the design
Answer:
Assuming that the squares are the same size,
the sum of the perimeter of the five squares =
(20 units × side length of each square in units)
If the squares are different sizes, the sum of the perimeter of the five squares =
(4 units × side length of square 1 in units) + (4 units × side length of square 2 in units) + (4 units × side length of square 3 in units) + (4 units × side length of square 4 units) + (4 units × side length of square 5 in units)
Explanation:
The perimeter of a square is 4 × side length because a square has 4 sides and the perimeter of a figure is the surrounding length of the figure.

Step-by-step explanation:
An object is launched from a platform.
Its height (in meters), xxx seconds after the launch, is modeled by:
h(x)=-5x^2+20x+60h(x)=−5x
2
+20x+60h, left parenthesis, x, right parenthesis, equals, minus, 5, x, squared, plus, 20, x, plus, 60
How many seconds after launch will the object land on the ground?
Answer:
6seconds
Step-by-step explanation:
Given the height of an object modeled by the expression
h(x)=-5x^2+20x+60
The height of the object on the ground is zero i.e h(x) = 0
On substituting
h(x)=-5x^2+20x+60
0 =-5x^2+20x+60
Multiply through by -1
5x^2-20x- 60 = 0
Divide through by 5
x^2 - 4x - 12 = 0
x^2 - 6x + 2x - 12 = 0
x(x-6)+2(x-6) = 0
(x-6)(x+2) = 0
x - 6 = 0 and x+2 = 0
x = 6 and -2
Since time cannot be negative, hence it takes 6seconds after launch for the object land to on the ground

The speed that a tsunami (tidal wave) can travel is modeled by the eququation where S is the speed in kilometers per hour, and d is the average depth of the water in kilometers. A tsunami is traveling at 140 km/hr. What is the approximate average depth of the water? 0.133 km 0.145 km 0.155 km
Complete question :
The speed that a tsunami can travel is modeled by the equation s = 356 StartRoot d EndRoot, where S is the speed in kilometers per hour and d is the average depth of the water in kilometers. A tsunami is traveling at 140 km/hr. What is the approximate average depth of the water? 0.133 km 0.145 km 0.155 km
Answer:
0.155 km
Step-by-step explanation:
Given the tsunami speed relation :
S = 356√d
Given a tsunami speed of 140/hr
s = 140km/hr
S = 356√d
Make d the subject
Divide both sides by 356
s / 356= √d
Hence,
140 / 356 = √d
0.3932584 = √d
Square both sides
0.3932584² = d
d = 0.1546 km
d = 0.155 km
Answer:
0.155 km

Carol's car average is 17.1 miles per gallon in City driving and 24.7 miles per gallon in highway driving if she drove a total of 513.0 miles on 26 gallons of gas how many of the gallons were used for City driving
Answer:
the volume of the gas used for city driving is 17 gallons
Step-by-step explanation:
Given;
average speed for city driving, v₁ = 17.1 miles per gallon
average speed for highway driving, v₂ = 24.7 miles per gallon
total distance traveled, d = 513 miles
total gallon of gas used, t = 26 gallons
Let the volume of gas used for city driving = x
Also, let the volume used for highway driving = y
x + y = 26 -------- (1)
17.1x + 24.7y = 513 ------------(2)
From equation (1); y = 26 - x
Substitute the value of y in equation (2)
17.1x + 24.7(26-x) = 513
17.1x + 642.2 - 24.7x = 513
17.1x - 24.7x = 513 - 642.2
-7.6x = -129.2
x = 129.2/7.6
x = 17 gallons
Therefore, the volume of the gas used for city driving is 17 gallons
