75.5% of the students at Sarasota Community College are from in state. If 24,950 students are from in state, how many students attend the college?
Answer:
33046 students
Step-by-step explanation:
Find how many students attend the college by dividing 24,950 by 0.755
24,950 / 0.755
= 33046.36
Round down, since the answer has to be a whole number:
33046.36
= 33046
So, approximately 33046 students attend the college
If a picture measures 3 inches by 5 inches and it is dilated by a scale factor of 4, the new dimensions will be ________________________________________.
A. 12 inches by 20 inches
B. 15 inches by 15 inches
C. 7 inches by 9 inches
D. 0.75 inches by 1.25 inches
Answer:
A) 12 inches by 20 inches
Step-by-step explanation:
Dilation of a scale factor means to increase by a factor of 4.
That basically mean multiply the object by 4.
Therefore 3 inches x 4 = 12 inches
And 5 inches x 4 = 20
Angle A is circumscribed about circle O.
What is the measure of
Answer:
\( m\angle O = 134 \degree\)
Step-by-step explanation:
AC and AB are tangents to the circle with center O on points C and B respectively from point A.
Therefore
\( m\angle ACO=m\angle ABO=90\degree \)
\( m\angle CAB=46...(given) \degree \)
\(m\angle O = 360 \degree - (2 \times 90 \degree + 46 \degree) \\ \\ m\angle O = 360 \degree - (180 \degree + 46 \degree) \\ \\ m\angle O = 360 \degree - (226 \degree) \\ \\ m\angle O = 134 \degree\\ \\ \)

The shapes below are drawn on a centimetre grid. Show that the triangle and the square have the same area.
Both figures have an area of 4 units squared, so yea, the area is the same.
How to find the areas?The area of a square of side length S is equal to S squared, for the square, we can see that:
S = 2 units.
Then the area is:
A = (2 units)² = 4 square units.
For the triangle, we know that the area is equal to:
A = B*H/2
Where B = base, H = height.
We can see that:
B = 2 units.
H = 4 units.
Then:
A = (2 units)*(4 units)/2= 4 square units.
So yea, both have the same area.

A cake is made from the ingredients listed below.
500 g flour, 450 g butter, 470 g sugar,
1.8 kg mixed fruit, 4 eggs (70 g each)
The cake loses 12% of its mass during cooking.
What is its final mass?
To make a cake :-
Quantity of flour needed = 500 g
Quantity of butter needed = 450 g
Quantity of sugar needed = 470 g
Quantity of mixed fruit needed = 1.8 kg = 1000 g + 800 g
Quantity of eggs needed = 70 × 4 = 280 g
It's weight after adding all the ingredients =
=500 + 450 + 470 + 1000 + 800 + 280
= 3500 g
Mass that got lost while baking the cake :
= 12 % of 3500\( = \frac{12}{100} \: of \: 3500\)
\( = \frac{12}{100} \times 3500\)
\( =\frac{(12 \times 3500)}{100} \)
\( =\frac{42000}{100} \: g\)
\( = 420 \: g\)
Final mass = Initial mass - mass that got lost
\( = 3500 - 420 \: g\)
\( = 3080 \: g\)
∴ The final mass of the cake is 3080 g .

If ∠1 ≅ ∠2, can you conclude that any of the lines are parallel?
Explain.
A. Yes; lines n and p are parallel because corresponding angles are congruent.
B. No; ∠1 and ∠2 show no relationship.
C. Yes; lines ℓ and m are parallel because corresponding angles are congruent.
D. No; neither angle is formed by the transversal, line q.
A. Yes; lines n and p are parallel because corresponding angles are congruent.
According to the reverse of the comparable angles theorem, lines n and p are parallel if angles 1 and 2 are congruent.
The converse of the corresponding angles theorem is what?
According to the corresponding angles theorem, the corresponding angles on each line that a transversal cuts are congruent if the two lines are parallel to one another.
In contrast, lines that fall on those angles are parallel to one another if two corresponding angles are congruent to one another.
The diagram's angles 1 and 2 relate to one another.
In light of the converse of the equivalent angles theorem, lines n and p are parallel if angles 1 and 2 are congruent.

In triangle PQR, if P(3,4) is a vertex of the triangle and S(3,1) is middle point of QR , fimd the coordinates of centroid of the triangle.
PLS SOLVE THIS AND I WILL MARK U THE BRAINLIEST
Answer:
centroid = (3, 2)
Step-by-step explanation:
The centroid of a triangle is the point of intersection of the medians.
Given that S (3, 1) is the middle point of QR, this indicates that triangle PQR is an isoceles triangle with sides QP = PR and base QR. Therefore, the x-coordinate of the centroir will be x = 3.
Vertical distance between S and P = 3 units
Therefore, centroid will be 1/3 of SP. 1/3 of 3 = 1.
Therefore, y-coordinate of centroid = 1 + 1 = 2.

Acme Movers charges $45 plus $40 per hour to move household goods across town. Hank's Movers charges $55 per hour. For what lengths of time does it cost less to hire Hank's Movers?
The time when Hank's Movers will cost less is the point when the total charges is both Movers are Equal, the time is at 3 hours
Word ProblemGiven Data
Acme Movers charges $45Plus $40 per hour Hank's Movers charges $55 per hourLet x be the time takenFor Acme, the expression for the total charges is
Total = 45+40x ----------1
For Hank, the expression for the total charges is
Total = 55x ----------------2
Equating both expressions we have
45+40x = 55x
collect like terms
45 = 55x-40x
45 = 15x

At a certain bakery, the price of each doughnut is $1.S0. Let the random variable D represent the number of doughnuts a typical customer purchases each day. The expected value and variance of the probability distribution of' D are 2.6 doughnuts and 3.6(doughnuts) respectively. Let the random variable P represent the price of the doughnuts that a typical customer purchases each day. Which of the following is the standard deviation, in dollars, of the probability distribution of P? (A) 1.5(3.6) 1.513.6 Vi.5(3.6) 1.502.6) 1.512.6
The standard deviation of the probability distribution for the given price of each doughnut and the variance is equal to $√1.50 × 3.6.
Price of the each doughnut 'P' = $1.50
Expected value of the probability distribution of the doughnut = 2.6
Variance of the probability distribution = 3.6
Price of the variance of the probability distribution is equal to
= Price of each doughnut × Variance
= 1.50 × 3.6
Standard deviation of the probability distribution is equal to

Eva buys walnuts. The graph shows the relationship between the number of scoops and the cost of the walnuts. Which of the following are true statements about the graph? Choose all the correct answers. ✓ 2 4 Scoops Cost ($) N 0 0 6 8 A The point (2, 4) means that 2 scoops of walnuts cost $4. B Since the line passes through (1, 2), 1 is the constant of proportionality. C The graph is a proportional relationship. D The point (1, 2) means that the unit rate is $2 per scoop of walnuts. E The point (3,6) means that it costs $3 for 6 scoops of walnuts.
E and B cannot be true statements. The line through (1, 2) does not always suggest that 1 is the proportionality constant.
what is proportionality ?The idea of two quantities being associated in a fixed ratio or proportion is known as proportionality. The other way around is to say that if one item is multiplied by a specific factor, the second quantity is also multiplied by the same factor. In mathematics, this relationship is frequently represented as y = kx, where y and x are the two variables and k is the proportionality constant. This equation denotes that y is proportional to x. In many disciplines, including mathematics, physics, economics, and statistics, proportionality is frequently used.
given
Regarding the graph, the appropriate statements are:
Two scoops of walnuts cost $4, as indicated by the point (2,4), and the graph shows a proportional relationship.
D. The point (1,2) indicates that the price per serving of walnuts is $2.
Explanation:
A. The price for two scoops of walnuts is $4 because the point (2,4) is on the line.
C. Because the graph is a straight line that passes through the origin, the number of scoops and the price have a proportional relationship.
D. Because the point (1,2) is on the line, the price for 1 scoop of walnuts is $2. This is the cost per unit, also known as the unit rate.
E and B cannot be true statements. The line through (1, 2) does not always suggest that 1 is the proportionality constant. Also, because the point (3,6) is off the line, it cannot be used as a valid data point for this relationship.

-3(-3x-1) +2x+2=27
Answer:
\(x=2\)
Step-by-step explanation:
So we have the equation:
\(-3(-3x-1)+2x+2=27\)
First, distribute the -3:
\(9x+3+2x+2=27\)
Combine like terms:
\(11x+5=27\)
Subtract 5 from both sides:
\(11x=22\)
Divide both sides by 11:
\(x=2\)
So, the value of x is 2.
And we're done!
Steps to solve:
-3(-3x - 1) + 2x + 2 = 27
~Distribute
9x + 3 + 2x + 2 = 27
~Combine like terms
11x + 5 = 27
~Subtract 5 to both sides
11x = 22
~Divide 11 to both sides
x = 2
