Here's a recipe for pancakes:
250ml milk
120g flour
60 g butter
Grace makes some pancakes using 480g flour. How much butter does she need? How muck milk does she need?
Answer:
Milk: 1000 ml
Flour: 480 g
Butter: 250 g
Step-by-step explanation:
To calculate the amount of butter you have to figure out more flour she used.
First, 480 ÷ 120 = 4 So she uses 4 times the amount of flour.
Then, 60 × 4 = 240
Next, you need the amount of milk so we also multiply by 4.
250 × 4 = 1000
Lastly, have a great day!
Suppose a man has a mass of 76kg and a density of 0.92g/cm3.
A) Calculate his volume.
b) Calculate the mass of air that he displaces, using the density of air from Table 5.2. The density of air is 1.29kg/m3
c) Calculate the buoyant force on him due to the air he displaces and compare this to his weight in newtons.
Answer:
A) 0.08260 cubic meter
B) 106.554 grams
C) 1.044 Newton
Step-by-step explanation:
A) Volume = mass/density
Substituting the given values, we get -
Volume = [tex]\frac{76000}{0.92} =82608.69[/tex] cubic centimeter
[tex]= 0.08260[/tex] cubic meter
B) Mass = volume * density
Mass of air =
[tex]= 0.08260 * 1.29 \\= 0.106554\\[/tex]Kilogram
[tex]106.554[/tex] grams
C) Buoyant force = density * acceleration due to gravity * Volume
Buoyant force due to air =
[tex]0.08260 * 9.8 * 1.29 \\1.044[/tex]Kg-m/s or Newton
Nicholas has a pepper shaker in the shape of a cylinder. It has a radius of 9 mm and a height of 32 mm. How much pepper will fit in the shaker?
Answer:
8,138.88 mm³
Step-by-step explanation:
Volume of a cylinder = πr²h
Where,
π = 3.14
Radius, r = 9 mm
Height, h = 32 mm
Volume of a cylinder = πr²h
= 3.14 × (9 mm)² × 32 mm
= 3.14 × 81 mm² × 32 mm
= 8,138.88 mm³
Volume of a cylinder = 8,138.88 mm³
Quantity of pepper that will fit in the shaker = 8,138.88 mm³

Tom started an entertainment company. The net value of the company (in thousands of dollars) ttt months after its creation is modeled by v(t)=4t^2-24t-28v(t)=4t 2 −24t−28v, left parenthesis, t, right parenthesis, equals, 4, t, squared, minus, 24, t, minus, 28 Tom wants to know when his company will be at its lowest net value. 1) Rewrite the function in a different form (factored or vertex) where the answer appears as a number in the equation.
Answer:
[tex]v(t) = 4(t -7)(t +1)[/tex]
Step-by-step explanation:
Given
[tex]v(t) = 4t^2 - 24t - 28[/tex]
Required
Rewrite in a different form
To write in a factored form, we have:
[tex]v(t) = 4t^2 - 24t - 28[/tex]
Expand
[tex]v(t) = 4t^2 +4t- 28t - 28[/tex]
Factorize
[tex]v(t) = 4t(t +1)- 28(t +1)[/tex]
Factor out t + 1
[tex]v(t) = (4t -28)(t +1)[/tex]
Factorize 4t - 28
[tex]v(t) = 4(t -7)(t +1)[/tex]

Percy works two part-time jobs to help pay for college classes. On Monday, he works 3 hours at the library and 2 hours at the coffee cart and earns $36.50. On Tuesday, he works 2 hours at the library and 5 hours at the coffee cart and earns $50. His hourly wage at the library, x, and hourly wage at the coffee cart, y, can be determined using the system of equations below.
Answer:
Hourly wage at the library = x = $7.5
Hourly wage at the coffee cart = y = $7
Step-by-step explanation:
Let
Hourly wage at the library = x
Hourly wage at the coffee cart = y
On Monday, he works 3 hours at the library and 2 hours at the coffee cart and earns $36.50.
Hence:
3x + 2y = 36.5.... Equation 1
On Tuesday, he works 2 hours at the library and 5 hours at the coffee cart and earns $50.
2x + 5y = 50...... Equation 2
Combining both Equations
3x + 2y = 36.5.... Equation 1
2x + 5y = 50...... Equation 2
We solve using Elimination method, Multiply Equation 1 by 2 and Equation 2 by 3 which are coefficients of x to eliminate x
6x + 4y = 73 .. Equation 3
6x + 15y = 150...... Equation 4
Subtract Equation 3 from Equation 4
11y = 77
y = 77/11
y = 7
Solving for x using Equation 2
2x + 5y = 50...... Equation 2
2x + 5 × 7 = 50
2x + 35 = 50
2x = 50-35
2x = 15
x = 15/2
x = 7.5
Therefore,
Hourly wage at the library = x = $7.5
Hourly wage at the coffee cart = y = $7

Josephine has a glass pitcher in the shape of a rectangular prism. The pitcher dimensions are 5 inches long, 5 inches wide and 7 inches high. She fills 3 inches of the pitcher with sugar. How many cubic inches are left in her pitcher for lemonade?
Answer:
100 cubic inches
Step-by-step explanation:
If she fills 3 inches of the pitcher with sugar, the height will be reduced from 7 inches to 4.
Find how many cubic inches are left for lemonade by finding the volume
Use the volume formula, V = lwh
V = lwh
V = (5)(5)(4)
V = 100
So, there are 100 cubic inches left for lemonade
Which of these best describes π? A The area of a circle divided by its diameter. B The circumference of a circle divided by its radius. C The circumference of a circle times 3.14 D The ratio of a circle's circumference to its diameter
Answer: D. The ratio of a circle's circumference to its diameter
Step-by-step explanation:
Pi is the ratio of the circumference of a circle to its diameter which means that we get pie by dividing the circumference by the diameter. This relationship is true regardless of the size of the circle because the relationship between the circumference and the diameter does not change regardless of size.
Pi is very useful when calculating measures related to circles such as area and circumference. It also comes in handy for shapes that have circles in them such as cones.

Mr. Autry bought a hat for $99.90. He also bought a pair of boots for $89.90. What was the total cost of the hat and boots including an 8% sales tax
Answer:
$204.98
Step-by-step explanation:
Step 1: Add both item cost
[tex]99.90 + 89.90 = 189.80[/tex]
Step 2: Find the sales tax of the result
[tex]\frac{8}{100}\times 189.8 = 15.184[/tex]
Step 1: Convert 8% to fraction[tex]8\%= \frac{8}{100}[/tex]Simplify[tex]\frac{8}{100} = \frac{2}{25}[/tex]Step 2: Convert 189.80 to a fraction[tex]189.80 = \frac{189.8}{1}[/tex]Step 3: Set it up[tex]\frac{2}{25}\times \frac{189.8}{1}[/tex]Step 4: Cross divide[tex]189.80 \div 25 = 7.592\\2 \div 1 = 2[/tex]Step 5: Multiply the result[tex]7.592 \times 2 = 15.184[/tex]Step 3: Add the result from the total cost of both items
[tex]189.80 + 15.184 = 204.98[/tex]
The total cost of the hats and boots including sales tax is 204.98 dollars

Step-by-step explanation:
a football is kicked at an angle of 60 with initial velocity of 80 ft./s. approximately how far will the ball travel horizontally before it hits the ground?
4ft.
13ft
75ft
173ft
Answer:
75ft
Step-by-step explanation:
We are to find the maximum height reached by the ball. This is expressed as;
H = u²sin²Ф/2g
u is the initial velocity = 80 ft./s.
Ф is the angle = 60degrees
g is the acceleration due to gravity = 32ft/s
Substitute
H =80²sin²60/2(32)
H = 6400sin²60/64
H = 100 (0.8660)²
H = 100*0.749956
H = 74.9956
H ≈ 75ft
Hence the ball has travelled 75ft apprximately

Answer:
The answer is A
Step-by-step explanation:
In mathematics, a radical expression is defined as any expression containing a radical (√) symbol. Many people mistakenly call this a 'square root' symbol, and many times it is used to determine the square root of a number. However, it can also be used to describe a cube root, a fourth root, or higher.
