Mrs. lang has x amount of students in each class. Ms. easter has 4 less students in each class. If both teachers have 5 classes, write an expression that
shows how many students are in all of Ms. easter’s classes.

The interest he earns in 10 years =  $395.42.

What is compound interest?

The interest that is calculated using both the principal and the interest that has accrued during the previous period is called compound interest.

Here the Principal P = $500

Rate of interest= 6% = 6/100 = 0.06

Number of years t= 10 years.

Now using  compound interest formula then,

=> Amount = [tex]P(1+r)^t[/tex]

=> Amount = 500[tex](1+0.06)^{10[/tex] = [tex]500\times1.06^{10[/tex]

=> Amount = $895.42.

Now interest = $895.42 - $500 = $395.42

Hence the interest he earns in 10 years =  $395.42.

The population of Westville increased by approximately 99.95 people from 2015 to 2016.

To find the increase in population from 2015 to 2016 in Westville, we need to use the formula:

Increase in population = (Population density in 2016 - Population density in 2015) x Land area

First, we need to find the population density in 2016. To do that, we can divide the population of 2,000 people by the land area of 84.4 square miles:

Population density in 2016 = 2,000/84.4 ≈ 23.69 people per square mile

Next, we can plug in the values into the formula:

Increase in population = (23.69 - 22.5) x 84.4 ≈ 99.95 people

Answer: C

Step-by-step explanation:

1/2 pound of almonds = 5/6 cup of almond butter

To find out how much almond butter 1 pound of almonds will make, we need to multiply both sides of the equation by 2:

1 pound of almonds = (2 × 1/2) pounds of almonds = 2 × 5/6 cups of almond butter

Simplifying, we get:

1 pound of almonds = 5/3 cups of almond butter

So, a reasonable estimate for the amount of almond butter the recipe makes per pound of almonds is more than 2 cups of almond butter. Therefore, the answer is (c) more than 2 cups of almond butter.

Answer: b) between 1 1/2 and 2 cups of almond butter

Step-by-step explanation:

We can create a proportion to help us solve this question.

         [tex]\displaystyle \frac{\frac{1}{2} lbs\;almonds}{\frac{5}{6}lbs\;butter } =\frac{1lbs\;almonds}{xlbs\;butter}[/tex]

Now we can cross multiply.

         [tex]\displaystyle \frac{1}{2} *x=\frac{5}{6} *1[/tex]

         [tex]\displaystyle \frac{1}{2}x =\frac{5}{6}[/tex]

Next, we will divide both sides of the equation by one-half.

         [tex]\displaystyle x =\frac{5}{6}\div \frac{1}{2}[/tex]

         [tex]\displaystyle x =\frac{5}{6}* \frac{2}{1}[/tex]

         [tex]\displaystyle x =\frac{10}{6}[/tex]

Lastly, we will find which answer option this falls under by creating an improper fraction. This leads us to answer optoin b, b) between 1 1/2 and 2 cups of almond butter.

Answer:

c.) silver bikes

Step-by-step explanation:

Given the bike shop has 11 red bikes, 3 blue bikes, 12 silver bikes

here, the number orange bikes = 4

Given for every 1 orange bike there 3 __ bikes

Divide each number of bikes by the number of orange bikes  

For 11 red bikes

= 11/4 = 2.75    [which means for 1 orange bike 2.75 red bikes ]

For 3 blue bikes

= 3/4 = 0.75    [ which means for 1 orange bike 0.75 blue bikes ]

For 12 silver bikes

= 12/4 = 3        [ which means for 1 orange bike 3 silver bikes ]

For every 1 orange bike, there are 3  silver bikes.

There are 1820 different orders possible for selecting any 4 toppings out of a list of 16 toppings.

To calculate the number of different orders possible for selecting any 4 toppings out of a list of 16 toppings,

we can use the combination formula:

nCr = n! / r!(n-r)!

where n is the total number of items, r is the number of items to be selected, and ! represents the factorial operation.

Substituting the given values, we get:

16C4 = 16! / 4!(16-4)!

16C4 = (16 × 15 × 14 × 13) / (4 × 3 × 2 × 1)

16C4 = 1820

Therefore, there are 1820 different orders possible.

No, any court case should not be based solely on probabilities as probability does not imply certainty.

Compute the probability of another couple being in that area with the same characteristics

CHARACTERISTIC ASSUMED PROBABILITY

Drives a yellow car 1 out of 12

Man over 6 feet tall 1 /10

Man wearing tennis shoes 1/4

Man with beard 1/11

Woman with blond hair 1/3

Woman with hair in a ponytail 1 /13

Women over 6 feet tall 1/100

We will use the multiplication rule as all the characteristics should be present in the couple.

The probability of another couple being in that area with the same characteristics is given as

P(Drives a yellow car) x P(Man with beard) x P(Woman with blond hair) x P(Woman with hair in a ponytail) x P(Woman over 6 feet tall) = 1/12 x 1/11 x 1/3 x 1/13 x 1/100 = 1/514800

Answer:

To calculate how much is deducted from Scott’s paycheck, we need to first find out how much his employer pays for his health insurance premium.

55% of the annual premium is covered by the employer, so we can calculate this as:

0.55 x $20,969 = $11,532.95

Therefore, Scott’s employer pays $11,532.95 towards his health insurance premium.

To find out how much is deducted from Scott’s paycheck, we need to divide the remaining 45% of the premium by the number of pay periods in a year. Since Scott is paid biweekly, he receives 26 paychecks in a year.

45% of the annual premium is not covered by the employer, so we can calculate this as:

0.45 x $20,969 = $9,437.55

To find out how much is deducted from each biweekly paycheck, we can divide $9,437.55 by 26:

$9,437.55 ÷ 26 = $363.75 (rounded to the nearest cent)

Therefore, Scott’s employer pays $11,532.95 towards his health insurance premium and $363.75 is deducted from each of his biweekly paychecks for health insurance.

In mathematics, an equation is a statement that asserts the equality of two expressions, usually separated by an equals sign (=). An equation states that two expressions have the same value, and it provides a way to find the unknown values of variables by manipulating the expression using algebraic operations. Equations are used in a variety of fields, including physics, chemistry, engineering, economics, and many others, to model relationships and solve problems.

Here,

Let's call the length of the fourth side "x".

Since the three sides of the quadrilateral are the same length, we know that they are each equal to "q".

The perimeter of a quadrilateral is the sum of all its sides, so we can write:

q + q + q + x = 40

Simplifying, we get:

3q + x = 40

We also know that the length of the fourth side is 7 inches, so we can substitute that in for "x":

If two  lines intersect  at an angle of 90˚ or are perpendicular to each other, they form a right angle. A right angle is indicated by the symbol ∟Angle is always 90° or a right angle. The  opposite angle of 90° is the hypotenuse. The hypotenuse is always the longest side. The sum of the remaining two interior angles is  90°.  In a right-angled triangle, the side opposite  the 90-degree angle is called the hypotenuse, indicated by the letter "c". The sides adjacent to a 37 degree angle and a right angle are called "ab" and "bc" respectively.  

Using trigonometry, we  find the length of "ab" as follows:

sin(37) = opposite/hypotenuse = ab/c

ab = sin(37) * c

Substituting the given values ​​we get:

ab = sin(37) × 10 cm
