Banana Cupcakes
makes 10 cupcakes
1 cup granulated sugar
cup vegetable oil
1 large egg
4 tablespoons sour cream
2 medium-sized ripe bananas, mashed
1 cups all-purpose flour
1 teaspoon baking soda
teaspoon salt
1 teaspoon vanilla extract
pinch of nutmeg
You will use the recipe above to answer the following questions:
This recipe serves 10, but you need to serve 30. What number will you need to multiply the amount of each ingredient by to adjust the recipe? How did you determine this number?
How much vegetable oil do you need for 30 cupcakes?
How much flour do you need for 30 cupcakes?
What is the difference in the amount of vanilla extract you would need for 30 cupcakes?
What is the difference in the amount of salt you would need for 30 cupcakes?
In the real world, even though you make adjustments to a recipe to accommodate the number of people you need to serve, you sometimes round the amount of an ingredient instead of using an exact amount. Which ingredient would it make more sense to round rather than coming up with the exact amount? Why?
Answers
Answer: Hey give me 1 hour and ill answer it I'm doing odessyware rn so Ill get back to you later appreciate yo patients.
Step-by-step explanation:
Then, if we want to make 30 servings, we need to use that recipe 3 times. (because x*10 = 30, then x = 30/10 = 3)
This would be equivalent to multiply each ingredient by 3.
for 30 cupcakes we need:
3 cups of vegetable oil.
3 cups of all-purpose flour
(because for each one of these ingredients we needed only 1 cup to make 10 cupcakes).
for 10 cupcakes we need 1 teaspoon of vanilla.
for 30 cupcakes we need 3 teaspoons of vanilla, the difference is 3 - 1 = 2.
So the difference is 2 teaspoons.
About which quantities we should round are those where we may have mixed numbers or big numbers.
For example, we have 4 tablespoons of sour cream for 10 servings, then for 30 servings we should have:
3*4 = 12 tablespoons.
We could round this down to 10 tablespoons.

Part B: What would be a better line of best fit for the scatter plot?
Part C: How does the actual line of best fit compare with Jeff's line?
Answers
Answer:
The line of best fit would not be right because there would be a big gap of space. The line should be the cooardinate 7,3 as this covers the line and the cooardinate 7,7 is an outlier. The new line is more accurately placed
Step-by-step explanation:
Answer:
The actual line of best fit would be from (0, 0) to (7, 4), this is because it covers majority of the points. All the other points are just anomalies. Moreover, Jeff's line is NOT the line of best fit because it is not accurate and is out of place. Furthermore, the actualy line of best fit is 3 places lower on the y-axis then Jeff's line of best fit.

What is the height of a cylinder with a radius of 3 and a volume of 189?
Answers
Answer:
6.68 units (2 d.p.)
Step-by-step explanation:
The formula for the volume of a cylinder is:
\(\boxed{V=\pi r^2 h}\)
where:
V is the volume.r is the radius of the circular base.h is the height.Given values:
V = 189 cubic unitsr = 3 unitsTo find the height of the cylinder, substitute the given values into the formula and solve for h:
\(\implies 189=\pi \cdot 3^2 \cdot h\)
\(\implies 189=9\pi \cdot h\)
\(\implies \dfrac{189}{9 \pi}=\dfrac{9\pi \cdot h}{9 \pi}\)
\(\implies \dfrac{189}{9 \pi}=h\)
\(\implies h=6.6845076...\)
Therefore, the height of a cylinder with a radius of 3 units and a volume of 189 cubic units is 6.68 units (2 d.p.).

It takes 17 seconds for a train to pass a 206-meter long bridge at normal speed. It takes 45 seconds for the same train to pass 170-meter long bridge at one-third of the normal speed. What is the length of the train in meters?
Answers
Answer:hello
Step-by-step explanation:sync bien
- L = length of the train in meters
- v = speed of the train in meters per second (normal speed)
- t1 = time taken by the train to pass the 206-meter long bridge at normal speed
- t2 = time taken by the train to pass the 170-meter long bridge at one-third of the normal speed
From the problem statement, we have two equations involving these variables:
Equation 1: L + 206 = v * t1
Equation 2: L + 170 = (1/3)*v * t2
We can solve this system of equations for L by eliminating v. To do this, we can rearrange Equation 1 to solve for v:
v = (L + 206) / t1
Then, we can substitute this expression for v into Equation 2:
L + 170 = (1/3)*[(L + 206) / t1] * t2
Multiplying both sides by 3*t1 and simplifying, we get:
3*L*t1 + 3*170*t1 = (L + 206)*t2
Expanding the right-hand side and simplifying, we get:
3*L*t1 + 510 = L*t2 + 206*t2
Now, we can solve for L by rearranging terms and simplifying:
L = (206*t2 - 3*170*t1) / (3*t1 - t2)
Substituting the given values, we get:
L = (206*45 - 3*170*17) / (3*17 - 45) = 510
The length of the train is 510 meters.

Step-by-step explanation:
Answer:
a. 7.4 cm

a. Apply Pythagorean theorem to find h.
c² = a² + b²
Where,
c = 8 cm
a = 3 cm
b = h cm = ?
Plug in the values
8² = 3² + h²
64 = 9 + h²
64 - 9 = h²
55 = h²
h = √55
h ≈ 7.4 cm
b. Area of the triangle = ½*bh
b = 6 cm
h = 7.4 cm
Area = ½*6*7.4
