Find the value of X: 28 507 20 10
Answers
Answer:
Given the information, the value of x is 20.
Step-by-step explanation:
For this problem, we have to find the ratio between the line segments in order to find the value of x.
We are already given two line segments that we can find the ratio for. We are given 30 and 12. In order to find the ratio, then we must divide 12 by 30.
12 ÷ 30 = 0.4
Now that we have our ratio, we can now divide 8 by 0.4 to find the value of x.
8 ÷ 0.4 = 20
So, the value of x is 20 which is the third answer choice in the problem.
12/30=y/25
y=10
10/8=25/x
x=28
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.

The function for the points are y = -15x - 5
How to determine the functionFrom the information given, we have that;
The points are;
(1/3,0) (-2 3/4,0) and (0,-5)
Using the point-slope form of a linear equation, we have;
y - y₁ = m(x - x₁)
Such that;
m is the slope of the liney - y₁ and (x - x₁) are the pointsUsing (1/3, 0) and (0, -5), we have that the slope is;
m = (0 - (-5))/0 -1/3)
expand the bracket
= 5 / (-1/3)
= -15
Now, take any of the given points and substitute the values
Using (1/3, 0), we get;
y - 0 = -15(x - 1/3).
y = -15x - 5.

The function for the points solved by (1/3,0) (-2 3/4,0) and (0,-5) solved by point slope form is \(a=-15b-5\)
We have given the points:
(1/3,0) (-2 3/4,0) and (0,-5)
Using the formula of linear equation
\(a-\)\(a_{1}\)\(=x[b-b_{1}]\)
Where we will consider (1/3,0) = \(a-a_{1}\) and (0,-5) = \(b-b_{1}\)
that is 1/3 = \(a\), 0 = \(a_{1}\) and
0 = \(b\), -5 = \(b_{1}\)
\(x\) refers to the slope of line (take any variable)
Now for finding the value of \(x\),
\(x=a-a_{1}/b-b_{1}\)
inserting the values,
\(x=[0-[-5]]/[0-1/3]\\x= -15\)
Substitute the value of \(x\) in the equation
\(a-0=-15[b-1/3]\)
By simplifying the equation, we get

Robin invests $1500 at 4.85% compounded quarterly, Write an equation to represent the amount of money he will have in n years. How much money will Robin have in 12 years?
Answers
Answer:
A=1500(1+ .0485/4)^4(12)
Step-by-step explanation:
The .0485/4 Is a fraction representing the 4.85% compounded quarterly, and the ^4(12) is the power of 4 multiplied by 12 (# of years).
The amount of money Robin will have in n years is $1500 ( 1.012125)⁴ⁿ.
The amount of money Robin will have in 12 years is $2675.04
What is compound interest?The interest charged on a loan or deposit is known as compound interest. It is the idea that we employ the most frequently on a daily basis. Compound interest is calculated for an amount based on both the principal and cumulative interest. The major distinction between compound and simple interest is this.
Investment amount = $1500.
Quarterly compounded interest rate = 4.85%.
Hence, the amount of money Robin will have in n years:
= $1500 ( 1 + 4.85%/4)⁴ⁿ
= $1500 ( 1 + 1.2125%)⁴ⁿ
= $1500 ( 1 + 1.2125/100)⁴ⁿ
= $1500 ( 1 + 0.012125)⁴ⁿ
= $1500 ( 1.012125)⁴ⁿ
Hence, the amount of money Robin will have in 12 years:
= $1500 ( 1.012125)⁴ ˣ ¹²
= $1500 ( 1.012125)⁴⁸
= $2675.04

A new bank customer with $3,000 wants to open a money market account. The bank is offering a simple interest rate of 1.9%. a. How much interest will the customer earn in 30 years? b. What will the account balance be after 30 years?
pls answer fast due in 10 minutes
Answers
Simple interest = Principal * Rate * Time
Here, the principal (P) is $3,000, the rate (R) is 1.9%, and the time (T) is 30 years.
Simple interest = $3,000 * 0.019 * 30 = $1,710
Therefore, the customer will earn $1,710 in interest over 30 years.
b. To calculate the account balance after 30 years, we can add the interest earned to the principal:
Account balance = Principal + Interest
Account balance = $3,000 + $1,710 = $4,710
Therefore, the account balance will be $4,710 after 30 years.
a. To calculate the interest earned in 30 years, we can use the simple interest formula:
Simple interest = Principal * Rate * Time
Here, the principal (P) is $3,000, the rate (R) is 1.9%, and the time (T) is 30 years.
Simple interest = $3,000 * 0.019 * 30 = $1,710
Therefore, the customer will earn $1,710 in interest over 30 years.
b. To calculate the account balance after 30 years, we can add the interest earned to the principal:
Account balance = Principal + Interest
Account balance = $3,000 + $1,710 = $4,710
Therefore, the account balance will be $4,710 after 30 years.
