Answer:
C. 6%
Step-by-step explanation:
First we need to divide the amount of people who got the allergic reaction by how many people were there.
So: 12 ÷ 200 = 0.06
Now, we need to multiply 0.06 by a whole percent, the whole percent is 100.
So: 0.06 × 100 = 6
6% of the people had a mild allergic reaction.
Daniel has a coupon for $1.44 off
name-brand flour that usually costs
$9.12. The store-brand flour costs $8.86.
How much will Daniel save by using his
coupon to buy the name-brand flour,
instead of buying the store-brand?
I’m mostly struggling with the problem steps part I can do the first parts but then the other steps I struggle with.
Answer:
Daniel will save $1.18
Step-by-step explanation:
First, find the cost of the name-brand flour with the coupon:
Subtract 1.44 from the original price of 9.12:
9.12 - 1.44
= 7.68
So, the price of the name-brand flour with the coupon is $7.68
Now, find how much he will save by finding the difference between this price and the price of the store brand flour:
8.86 - 7.68
= 1.18
So, Daniel will save $1.18

Triangle PQR is dilated by a scale factor of 1.5 to form triangle P′Q′R′. This triangle is then dilated by a scale factor of 2 to form triangle P″Q″R″. If vertex P is at (3, -4) and vertex Q is at (5, -1), what are the coordinates of vertices P″ and Q″?
Answer:
Answer: The correct option is (D) P″(9, -12) and Q″(15, -3).
Step-by-step explanation: Given that triangle PQR is dilated by a scale factor of 1.5 to form triangle P′Q′R′. This triangle is then dilated by a scale factor of 2 to form triangle P″Q″R″.
The co-ordinates of vertices P and Q are (3, -4) and (5, -1) respectively.
We are to find the co-ordinates of the vertices P″ and Q″.
Case I : ΔPQR dilated to ΔP'Q'R'
The co-ordinates of P' and Q' are given by
Case II : ΔP'Q'R' dilated to ΔP''Q''R''
The co-ordinates of P'' and Q'' are given by
Thus, the co-ordinates of the vertices P'' and Q'' are (9, -12) and (15, -3).
Option (D) is CORRECT.

The 600 mile, Texas Gulf Coast has various barrier islands that protect the coast from storms. If each barrier island is an average of 75 miles in length, how many barrier islands are there?
Answer: 8 barrier island.
Step-by-step explanation:
From the question, we are informed that Texas Gulf Coast is about 600 miles and that it has various barrier islands that helps protect the coast from storms.
We are further told that each barrier island is an average of 75 miles in length. Therefore, the number of barrier islands that are there will be gotten by dividing 600 by 75. This will be:
= 600 / 75
= 8 barrier island

Janna and Travon are creating posters for the school play. Together they will have f(t) posters after creating posters for t hours. f(t) = 5t + 3 The function f represents the fact that every hour —
Answer:
8posters are created
Step-by-step explanation:
Given the function that represents the total number of posters expressed as
f(t)= 5t+3
The total posters every hour occur at t = 1hr
Substitute into the equation
f(1) = 5(1)+3
f(1) = 5+3
f(1) = 8
Hence the function f represents the fact that every hour, 8posters are being created

Answer:
9x² + 16y² - 24xy
Step-by-step explanation:
(3x - 4y)²
⇒ (3x)² + (4y)² - 2 (3x) (4y) {(a - b)² = a² + b² - 2ab}
⇒ 3²x² + 4²y² - 2 (12xy)
⇒ 9x² + 16y² - 24xy

Answer:
The measure of angle Q is 133 degrees
Step-by-step explanation:
(x + 13) + (10x + 13) + (2x - 2) = 180 //There are 180 degrees in a triangle
x + 13 + 10x + 13 + 2x - 2 = 180 //Remove parentheses
13x + 24 = 180 //Combine like terms
13x = 156 //Subtract 24 from each side
x = 12 //Divide to get value of x
10(12) + 13 = Measure of angle Q //We know Q is 10x + 13, since we know what x is 12 from the previous step we'll substitute x for 12
120 + 13 = Measure of angle Q //Multiple 10 and 12
133 = Measure of angle Q
Jesse added two more numbers to his expression, but the sum did not change. What could the two new numbers be? Explain why the numbers you chose would not affect the sum of Jesse’s expression.
Answer:
0 and 0
Step-by-step explanation:
The only number that can be applied to the expression without changing the sum is 0, for example 5 + 10 = 15, adding 2 0's will be 0 + 5 + 10 + 0 = 15 :D

Equation: -2(2x + y) = 28.
Answer:
x=-14-y/2
Step-by-step explanation:
divide both sides by -2
-2(2x+y)/-2=28/2
simplify
2x+y=-14
subtract y from both sides
2x+y-y=-14-y
simplify
2x=-14-y
divide both sides by 2
2x/2=-14/2-y/2
simplfy
x=-14-y/2

Write the equation in slope-intercept form. Do not use any spaces. Make sure your answer looks like y=mx+b. Y + 6 = 3(x - 4) *
Answer:
y = 3x+ 18
Step-by-step explanation:
Given the expression y + 6 = 3(x-4), we are to express in the form y = mx+b
Open the bracket
y + 6 = 3(x-4)
y+6 = 3x-12
Collect the like terms;
y - 3x = -12 - 6
y - 3x = 18
y = 3x + 18
Hence the required equation in slope-intercept form is y = 3x+ 18

A surveyor is studying a map of the community and is using vectors to determine the distance between two schools. On the map, the surveyor determined that school A is at (7, 12), and school B is at (–21, –13). The scale of the map is 1 unit = 100 meters.
Which vector represents the path from school A to school B, and what is the actual distance between them?
a) components: LeftAngleBracket 28, 25 RightAngleBracket, actual distance: about 37.54 meters
b) components: LeftAngleBracket 28, 25 RightAngleBracket, actual distance: about 3,754 meters
c) components:LeftAngleBracket negative 28, negative 25 RightAngleBracket, actual distance: about 37.54 meters
d) components:LeftAngleBracket negative 28, negative 25 RightAngleBracket, actual distance: about 3,754 meters
Answer:
C: <-28,-25>, etc.
Step-by-step explanation:
The vector from A to B is (-28, -25) and the distance between A to B is 3754 meters.
What is Coordinate Geometry?One of the most intriguing ideas in mathematics is called coordinate geometry. By using graphs with curves and lines, coordinate geometry (also known as the analytic geometry) explains how geometry and algebra are related. They can answer geometrical problems because it gives them geometrical aspects of algebra. In this area of geometry, a pair of ordered numbers is used to describe the location of points on a plane.
As per the given data:
Coordinates of school A = (7, 12)
Coordinates of school B = (-21, -13)
Scale of the map is 1 unit = 100 m
For vector representing the path A to B:
Final - Initial coordinates
= (-21 - 7, -13 - 12)
= (-28, -25)
Distance between A and B:
Distance formula = [tex]\sqrt{(x_2 - x_1)^2 + (y_2 - y_1)^2}[/tex]
= [tex]\sqrt{(-21 - 7)^2 + (-13 - 12)^2}[/tex]
= 37.54 units {1 unit = 100 m}
= 3754 meters
Hence, the vector from A to B is (-28, -25) and the distance between A to B is 3754 meters.

Racquel works 4 hours a week at the senior center on the weekends.
She gets paid $10.75 an hour. How much money will Raquel have
earned over the course of 3 weeks?
Answer:
$129
Step-by-step explanation:
First, we'll figure out how much Racquel earns per week by multiplying how much she gets per hour by the number of hours she works per week. We can solve 4x10.75 to find out how much money Racquel earns per week. We can solve that to find out that she earns $43 per week. Then, we can multiply that by 3 to find out how much she earns in 3 weeks. Once we solve 43x3 we will end up with an answer of $129 over the course of 3 weeks.

Which input value produces the same output value for the two functions on the graph?
f)--x1
ot) -x-2
3
g(x)
9514 1404 393
Answer:
x = 3
Step-by-step explanation:
Each line shows you the output value for a given input value. If you want a particular input value to give the same output for both functions, then you need to find the point where the lines cross. This question asks for the input value at that point, the x-coordinate.
The lines cross at (x, y) = (3, -1), so x = 3 produces the same output from both functions.
