If Pete sells 50 pizzas, he will make a profit of $75. The equation can be used to determine the profit is y = 5.50x - 200.

Pete's Pizzas charges $5.50 per pizza and has spent $200 in supplies to start his business.

We can use the following equation to determine the total profit he will make after he sells x amount of pizzas:

y = 5.50x - 200

where y is the total profit, 5.50 is the revenue per pizza, x is the number of pizzas sold, and -200 is the fixed cost for the supplies.

For example, if Pete sells 50 pizzas, we can plug in the values into the equation:

y = 5.50 * 50 - 200

y = 275 - 200

y = 75

So, if Pete sells 50 pizzas, he will make a profit of $75. The equation can be used to determine the profit for any number of pizzas sold by simply changing the value of x.

He stands 6 feet tall, and his shadow extends 9 feet. if the building's shadow extends for 322.5 feet.

Now 6/9 = X/322.5

9X = 1935

X = 215ft

The Height of the building = 215ft

Consider an object AB of height h such that its shadow of length s is formed and angle of elevation is θ.

The object AB depicts a right triangle in which ∠ABO = 90o.

Now we know that in trigonometry, the tangent ratio for an angle is equal to the opposite side to that angle divided by its adjacent side.

So, for the angle of elevation θ, we have

=> tan θ = AB/OB

Putting AB = h and OB = s, we get

=> tan θ = h/s

=> s/h = 1/tan θ

Answer:x=\frac{b-1}{a-d}

Step-by-step explanation:

Answer:

Jamie has $12.50 of her allowance left if the books cost $2.50 each.

Step-by-step explanation:

To calculate this, first calculate the total cost of the books:

5 books x $2.50/book = $12.50.

Then subtract the cost of the books from the amount Jamie has saved:

$38 - $12.50 = $25.50.

Finally, subtract the cost of the books from the amount Jamie has saved to get the amount she has left:

$25.50 - $12.50 = $12.50.

Answer:

$25.50

Step-by-step explanation:

We know Jamie bought 5 books, each worth $2.50, d. We need to know the cost of all five, so we’ll go ahead and multiply 5 times $2.50 to get $12.50.

Since we know how much the books cost, all we have to do now is subtract the amount she spent from her allowance. $38.00 - $12.50 is 25.50, the amount of money Jamie has left.

A limit describes a function's value as it gets closer to a certain value as its inputs increase. All calculus is based on the concept of a limit.

There are one-sided limits (left- and right-hand limits), infinite limits, and limitations at infinity in addition to regular, two-sided limits.

Let's look at an example to better grasp what limits are. Beginning with the function f (x) = x + 2 f(x) = x + 2 f(x) = x + 2f, left parenthesis, x, right parenthesis, equals, x, plus, 2. The value f approaches as we move closer and closer to x = 3 x=3 x=3, which is the limit of f at x = 3 x=3 x=3.

The values of the two limits are lim x->33- g(x) = -15 and lim x->33+ g(x) = -6.

Option (B) is correct.

What is a limit in calculus?

The limits in mathematics describe the behavior of a function as the input approaches a certain value. The symbols for limits are "lim" followed by the variable and the value that the variable is approaching, with an arrow indicating the direction of the approach.

For the given function g(x), we have the following limits:

lim x->33- g(x) = -15.1

This means that as x approaches 33 from below, the value of g(x) approaches -15.1. We can see this from the values in the table, as x gets closer to 33 from below, g(x) gets closer to -15.1.

lim x->33+ g(x) = -6.1

This means that as x approaches 33 from above, the value of g(x) approaches -6.1. We can see this from the values in the table, as x gets closer to 33 from above, g(x) gets closer to -6.1.

So, the values of the two limits are lim x->33- g(x) = -15.1 and lim x->33+ g(x) = -6.1.

Hence, The values of the two limits are lim x->33- g(x) = -15 and lim x->33+ g(x) = -6.

Note that where in a Rhombus ACDB, m∠CDB = 60 degrees and BC = 10. The diagonals cross at point M. The length of the side of ACDB is 10.

A rhombus is a quadrilateral with four equal-length sides in planar Euclidean geometry. The term equilateral quadrilateral refers to the fact that all of its sides are the same length.

Note that the above-described Rhombus is described accordingly. Since the diagonals are perpendicular to each other and bisect one another each at an inner angle that is 90° each, then we can say that;

∠MDC = 30°
MC = 1/2BC

= 1/2 * 10
= 5

Thus,

DC = MC/Sin30°

The best discrete variable of measurement for the situation is an interval.

Finding the scale of measurement for the variables is the next step in selecting a statistical test after identifying the independent and dependent variables. The dependent variable must be measured using an interval or ratio scale for each of the parametric tests that we have covered so far. Many psychologists also subject variables with roughly interval scales of measurement to parametric tests. You must decide whether to use "scale" or "interval" scores when performing parametric tests of means.

Given the condition about whether the race of the defendant has an impact on jury verdicts,

The best scale of measurement for the condition is an interval.

Although the interval scale has characteristics of nominal and ordered data, it also allows for the quantification of data point differences. The variables' actual positions in the order as well as their differences are both displayed by this form of data. They can be combined or split, but not added to or subtracted from. 

The fact that zero is an existing variable adds another characteristic to this scale. Zero in the ordinal scale indicates that there is no data.

A polygon's vertex is a location where the sides or edges of the item or two rays or line segments meet. Vertex is a noun, whereas vertices is the plural. Vertices are the points at which the edges of the three-dimensional shape converge. Edges are the lines that separate two faces, while faces are flat surfaces.

f(1/7) = 3 3/4 in simplest form.

Step-by-step explanation:

To find the value of f(1/7), we can substitute 1/7 for x in the function:

f(1/7) = -7/4 * 1/7 + 4

f(1/7) = -7/4 * 1/7 + 4

f(1/7) = -7/28 + 4

f(1/7) = 4 - 7/28

f(1/7) = 4 - 1/4

f(1/7) = 3 3/4

So f(1/7) = 3 3/4 in simplest form.

Step-by-step explanation:Let the total daily pocket money of the 35 pupils in the other class "A" and the total daily pocket money of all 80 pupils "B".

The mean daily pocket money of the 35 pupils in the other class is m cents, so:

A = 35 * m

The mean daily pocket money of all 80 pupils is 72.25 cents, so:

B = 80 * 72.25

Since we know the total pocket money of both classes, we can use this information to solve for m:

A + B = 115 * m

35 * m + 80 * 72.25 = 115 * m

35 * m = 115 * m - 80 * 72.25

35 * m = 115 * m - 5780

5780 = 115 * m - 35 * m

5780=80 * m

Finally, we can solve for m:

m = 5780/80

m = 72.25

It CANNOT equal 50, if it were there would not be -10x

20-5x=100-25x

DIVIDE BY 2 to get 50 WOULD GIVE:

20-5x=50-17.5x

Answer:

Yes

Step-by-step explanation:

solve the equation for x , then evaluate and compare both sides

20 - 5x = 50 - 10x ( add 10x to both sides )

20 + 5x = 50 ( subtract 20 from both sides )

5x = 30 ( divide both sides by 5 )

x = 6

then

left side = 20 - 5x = 20 - 5(6) = 20 - 30 = - 10

right side = 50 - 10x = 50 - 10(6) = 50 - 60 = - 10

since both sides are equal then

20 - 5x = 50 - 10x is true

It is important to note that the probability of an exact match at all 16 loci is very low, as even small differences in the number of repeats at each locus can result in different genotypes. This makes it unlikely to find two individuals with an exact match at all loci.

The field of mathematics concerned with probability is known as probability theory. Although there are various distinct interpretations of probability, probability theory approaches the idea rigorously mathematically by articulating it through a set of axioms. The probability is a measure of the possibility that an event will occur. It assesses the event's certainty. P(E) = Number of Favourable Outcomes/Number of Total Outcomes is the probability formula.

Here,

To calculate the probability of an identical match at all 16 STR loci, you would need to determine the frequency of each unique genotype at each locus, and then multiply the frequencies of each unique genotype to obtain the probability of all 16 loci having the same genotype in two individuals.
