Answer:
12:7
Step-by-step explanation:
Total number of kids = 76
Total number of kids that ordered chicken nuggets = 28
Total number of kids that did not order chicken nuggets = 76 - 28
= 48
The ratio of kids who did not order chicken nuggets to the number of kids who did is:
= 48 : 28
In simplest form :
= 12:7

Step-by-step explanation:
She needs to add one half of a teaspoon of salt, 1 and one fourth teaspoons of Oregano, three fourths of a teaspoon of Basil and half as much pepper as salt. What is the total number of teaspoons of spices in the dish? Express the answer as a decimal.
Answer:
Total number of teaspoons is 2.75
Step-by-step explanation:
Here, we want to know the total number of teaspoons of spices in the dish
we can calculate this by adding together the individual number of spices
That will be ;
1/2 + 1 1/4 + 3/4 + 1/2(1/2)
1/2(1/2) represents half as much pepper as salt
1/2 = 0.5
1 1/4 = 1.25
3/4 = 0.75
1/2(1/2) = 1/4 = 0.25
The total number of tea spoons will be;
0.5 + 1.25 + 0.75 + 0.25 = 2.75

PLEASE HELP!! what is the value of x? what is the value of y?
Answer:
x=36° y=66°
Step-by-step explanation:
3x+6+x+30 = 180° (Supplementary angles)
4x+36 = 180
4x = 180 - 36
4x = 144
x = 36
y+3x+6 = 180° (Supplementary angles)
y+3*36+6 = 180 (plug in the value of x)
y+108+6 = 180
y= 180-108-6
y = 66

You started a new job that pays $9.50 per hour. After 8 hours of work, you will get a bonus. Your boss tells you she
will pay you a total of $100 which includes the hourly pay and the bonus, at the end of the 8 hours. How much is the
bonus that you will receive?
Answer:
$24
Step-by-step explanation:
So because the rate of pay is 9.5 and hour, and they work 8 hours,
9.5 x 8 = 76
and because you make 100 after the 8 hours,
100-76 = 24

Jackrabbits are capable of reaching speeds up to 40 miles per hour. How fast is this in feet per second? Round to the nearest whole number
Answer:
59 feet per second.
Step-by-step explanation:
Firstly, we need to convert miles into feet and hours into seconds.
We know that there are 5280 feet in a mile.
To convert hours into seconds we multiply how many minutes are in an hour by how many seconds there are in a minute (60x60) to get 3600.
We multiply 5280 by 40 to get 211200 feet per hour
Because of the word "PER" we know that this is a divison problem.
211200 divided by 3600 is 58.66 repeating. Rounded to the nearest whole number makes it 59 feet per second.

If a data set is normally distributed, what percent of the data will lie above the mean? 99.7% 95% 68% 50%
The normal distribution is also known as the Gaussian distribution. The percentage of the data that will lie above the mean is 50%.
What is a normal distribution?The normal distribution, also known as the Gaussian distribution, is a symmetric probability distribution about the mean, indicating that data near the mean occur more frequently than data distant from the mean.
As we know that normal distribution is symmetric to the mean, therefore, If a data set is normally distributed, the percentage of the data that will lie above the mean is 50%.

Which values of x are solutions to this equation? |x/-4| = 2
-x = 4 or x = 8
-x = 2 or x = 6
-x = -2 or x = 2
-x = -8 or x = 8
Answer:
Step-by-step explanation:
|x/-4| = 2 corresponds to two different equations:
1) -x/4 = 2 if x/-4 is already positive, and
2) x/4 = 2 if -x/4 is negative, due to the absolute value operator
In case 1, -x = 8, or x = -8
and
in case 2, x = 8
so the solution set is {-8, 8}

Find the least common denominator (LCD) of
7/12 and 3/2
Answer:
12
Step-by-step explanation:
Rewriting input as fractions if necessary:
7/12, 3/2
For the denominators (12, 2) the least common multiple (LCM) is 12.
LCM(12, 2)
Therefore, the least common denominator (LCD) is 12.
Calculations to rewrite the original inputs as equivalent fractions with the LCD:
7/12 = 7/12 × 1/1 = 7/12
3/2 = 3/2 × 6/6 = 18/12

O 16
O 22
O24

Answer: 22
Step-by-step explanation:
6(4)-2
If f(x) = 6x - 2, the value of f(4) is 22. The correct option among the given ones is 2.
What is function?A function in mathematics is a relationship between a set of inputs (also known as the domain) and a set of outputs (also known as the range) that has the property that each input is related to exactly one output.
Functions are widely used in many branches of mathematics and are critical for modelling relationships between variables in fields such as science, engineering, and economics.
They are represented by equations or rules that specify how the output values are obtained from the input values.
The given function is f(x) = 6x - 2.
To find the value of f(4), we substitute x = 4 in the given function and evaluate:
f(4) = 6(4) - 2
f(4) = 24 - 2
f(4) = 22
Thus, the value of f(4) is 22, i.e., the correct option is 2.

Matt was babysitting for friend's parents Saturday morning and was paid an $10 per hour for 3 hours. Later that evening, he was baby sitting for another couple that paid him $20 per hour for 5 hours. What was Matt's average rate of pay per hour for the day?
Answer:
$16.25 per hour
Step-by-step explanation:
Given that:
First babysitting pay :
$10 per hour
Duration = 3 hours
Earning = $10 * 3 = $30
Second babysitting pay:
$20 per hour
Duration = 5 hours
Earning = 20 * 5 = $100
Average rate of pay per hour for the day:
Total amount earned / total hours worked
$(30 + 100) / (3 + 5) hours
$130 / 8 hours
= $16. 25 per hour
