Jessica is baking a cake. The recipe says that she has to mix 32 grams

Jessica is baking a cake. The recipe says that she has to mix 32 grams of vanilla powder to the flour. Jessica knows that 1 cup of vanilla powder has a mass of 128 grams. She added ¼ cup of vanilla to the flour. Should she add more vanilla powder to make the exact recipe, did she go over, or did she use the perfect amount? How do you know?

The expression 32/128 equals the amount of vanilla powder she needs to add to the cake because 32 is the amount of grams she needs to add and 128 is the amount of grams in a cup this expression is good because it represents the amount vanilla powder Jessica needs to add in cups since 32/128 simplifies to 1/4 Jessica needs to 1/4 of a cup of vanilla powder.

Answer: she used the perfect amount

Put the 200 dollars away and do some jobs to get money such as yard work

Question
One of Maria and Josie’s early tasks is printing and laminating signs to hang at local businesses around town. Working alone, Maria could print and laminate the signs in 4 hours. Josie, however, has better laminating equipment, so she could get the job done by herself in 2 hours. If each works for the same amount of time, how long will it take them working together to print and laminate the signs? Start by filling in the table with the missing values or expressions. Note that rate of work is a unit rate that describes the amount of the job completed in one hour.
Solution 1
Working together, it takes them 1 1/3 hours to complete the job.

Maria works at a rate of 1/4 of the job per hour, since she completes 1 job in 4 hours.
Josie works at a rate of 1/2 of the job per hour, since she completes 1 job in 2 hours.

Let x be the total number of hours it takes.
1/4x + 1/2x represents the time Maria and Josie work together.  1 will represent the entire job, since it is 100% of the job (100%= 100/100 = 1):

1/4x + 1/2x = 1

Find a common denominator; for this problem, we use 4:
1/4x + 2/4x = 1

Combine like terms:
3/4x = 1

Divide both sides by 3/4:
3/4x ÷ 3/4 = 1 ÷ 3/4
x = 1/1 ÷ 3/4
x = 1/1 × 4/3
x = 4/3 = 1 1/3
Question
A mother shares a box of 20 chocolates in the same ratio as her children's ages . Calculate how many chocolates each child gets if Sibusiso is 2 years old , Dorris is 3 years old and Freddy is 5 years old. Post a FULL explanation plz.
Solution 1
So a box of 20 chocolates is divided between a group of people based on age So the ratio for Sibusiso, Dorris, and Freddy is 2:3:5 Add these together, and you get 10 So to find how much each person gets, divide total amount of chocolates by total age So (20÷10) = 2 So multiply each age term by 2 and you have your answer (4:6:10) So Sibusiso gets 4, Dorris gets 6 and Freddy gets 10
Question
During one week, Josh ran 36 miles, Corey ran 26 miles, Rhona ran 30 miles, and Lyndsay ran 28 miles. What is the mean distance run by the four students? A. 29 miles B. 30 miles C. 36 miles D. 120 miles
Solution 1

The mean distance ran by all four of them is 30.

What are algebraic expressions?

  • In mathematics, an expression or mathematical expression is a finite combination of symbols that is well-formed according to rules that depend on the context.
  • Mathematical symbols can designate numbers (constants), variables, operations, functions, brackets, punctuation, and grouping to help determine order of operations and other aspects of logical syntax.

Given is that during one week, Josh ran 36 miles, Corey ran 26 miles, Rhona ran 30 miles, and Lyndsay ran 28 miles.

  • A mean in math is the average of a data set, found by adding all numbers together and then dividing the sum of the numbers by the number of numbers.
  • Mathematically, we can write -

       ${\displaystyle {\bar {x}}={\frac {1}{n}}\left(\sum _{i=1}^{n}{x_{i}}\right)={\frac {x_{1}+x_{2}+\cdots +x_{n}}{n}}}

We can write the mean as -

m = (36 + 26 + 30 + 28)/4

m = 120/4

m = 30

Therefore, the mean distance ran by all four of them is 30.

Solution 2
B.) 30 miles

You needed to add all the numbers together then divide by the amount of numbers there which is 4. (ex: 36 + 26 + 30 + 28 = 120  120÷4= 30)

Question
What is the circumference of a 12-inch diameter pizza? Leave the answer in terms of π.
Solution 1
Circumference of a circle = 2*π*radius of circle Radius = half of diameter =6in. So circumference = 2*π*6 =2π6
Solution 2
It  would be C=(πr)r. Hope i helped!
Question
If the radius of the circle is 4 cm, find its circumference. [Use 3.14 for π.]
Solution 1
r=4 \ cm \\ \pi=3,14 \\ \boxed{C-?} \\ \bold{Solving:} \\ \boxed{C=d \cdot \pi=2r \cdot \pi} \\ C=2 \cdot 4 \ cm \cdot 3,14=8 \cm \cdot \pi \\ \Rightarrow \boxed{C=25,12 \ cm}
Solution 2
Circumference = 2πr = 2*3.14*4 = 25.12
Question
high school student working part-time as a lifeguard had a gross income of $6596 last year. If his federal tax rate was 10% and his state tax rate was 4.15%, what was the amount withheld from his pay last year in federal tax, state tax, and FICA combined?
Solution 1

1437.93 is the answer here my guy


Solution 2
It should be $933.33 combined, since 14.15(federal tax rate and state tax rate) of 6596 is $
933.33
Question
Your gross income is $4,520.00/month. Your deductions are FICA (7.65%), federal tax withholding (11.75%), and state tax withholding (8.5%). Your fixed expenses are 30% of your realized income. You saved 5 months' worth in an emergency fund, placing 75% in a 60-day CD at a 5.25% APR and the rest in a regular savings account at a 3.8% APR. What is the total amount of your emergency fund?
Solution 1

Answer:

$11,406.20

Step-by-step explanation:

7.65% of 4520 is

0.0765(4520) = 345.78.  This is what is withheld for FICA.

11.75% of 4520 is

0.1175(4520) = 531.10.  This is what is withheld for federal tax.

8.5% of 4520 is

0.085(4520) = 384.20.  This is what is withheld for state tax.

This leaves 4520-(345.78+531.10+384.20) = 3258.92 for realized income.

Your fixed expenses are 30% of this; this means you keep 100-30 = 70% of your realized income.  This is

0.7(3258.92) = 2281.24.  This is the monthly amount you have after fixed expenses.

This means 5 months' worth is 5(2281.24) = 11460.20.


Solution 2
1st we need to calculate the take-home net monthly income, 2nd deduct 30% expenses then × 5 mos, then last calculate the rates for emergency fund (EF).

1) $4,520.00/month - [4520 × (FICA (7.65%) + federal tax (11.75%) + state tax (8.5%))]
= 4520 - [4520 × 0.279] = 4520 - 1261.08
= 3258.92

2) less 30% expenses every month = 3258.92-(3258.92×0.30) = 3258.92×0.70 = 2281.24,
2281.24 × 5 mos = 11,406.22

3) EF = CD + savings acct
75% of 11,406.22 = 8554.67 in 60-day CD
25% × 11,406.22 = 2851.56 in savings acct

If they want to know what this EF is at a certain point in the future, that should have been asked. Otherwise the beginning total amt of the EF after saving for 5 mos = $11,406.22
