Katherine is visiting patients in a hospital. She visits 18 patients in 6 hours. At that rate, how many patients will she visit in 9 hours?
Answer:
Let's find the unit rate first, I like to order my units:
Patients 18 3 patients_________ = ______ = ______________, so 3 patients per hour is the
Hours 6 1 hour-unit rate.
Now let's order them to equal x(unknown patients)/9(hours)
3 patients (x9) x___________ = __________ = 27 patients per 9 hours. So your answer
1 hour (x9) 9is 27 patients.
Answer:
27 patients
Step-by-step explanation:
18patients = 6 hours
18/6 = 3
each hour for 6 hours she attends to 3 patient
6 hours + 3 hours make up 9 hours
since for each hour she attended to three patients we would say
1 hr = 3 patients
1 hr = 3 patients
1 hr = 3 patients
Total: 3 hrs = 9 patients
18 patients + 9 patients = 27 patients
so for 9 hrs Katherine will visit 27 patients.

Suzanne bought a sweater at the sale price of 87.50. Originally, the sweater sold for $140. What was the percent discount? ( please help me! )
Answer:
37.5%
Step-by-step explanation:
the savings on the sweater is 140-87.50, or 52.50
you could create a proportion based on the statement:
52.50 is what percent of 140?
is/of = 'x'/100
52.5/140 = x/100
cross-multiply to get:
140x = 5250
x = 5250/140
x = 37.5

Answer:
65
Step-by-step explanation:
It’s 65 because 65+35=100 then u add 80 to get 180
The measure of the third angle in the triangle is 65°. The correct option is B.
What is geometry?One of the earliest areas of mathematics is geometry, along with arithmetic. It is concerned with spatial characteristics like the separation, shape, size, and relative placement of objects.
Given that Triangle P Q R. Angle Q is 80 degrees and angle P is 35 degrees. Triangle W X Y. Angle W is 35 degrees and angle X is 80 degrees.
The third angle will be calculated as:-
Angle = 180 - 80 - 35
Angle = 65
Therefore, the measure of the third angle in the triangle is 65°. The correct option is B.

Write a quadratic equation with the given solutions below such that the terms of the quadratic contain no common factors.
-3,1
Answer:
x² +2x -3 = 0
Step-by-step explanation:
Given the zeros of a quadratic function the factored form is easily found. There is a factor (x -p) for each zero x = p. Here, the factored form of the function is ...
0 = (x -(-3))(x -1) = (x +3)(x -1)
In standard form, this is ...
x(x -1) +3(x -1) = 0
x² +2x -3 = 0 . . . . . . the terms have no common factors

Answer:
-7n - 3
Step-by-step explanation:
5n-3(4n+1) =
5n -12n -3= 0
-7n - 3
Answer: -7n-3
Step-by-step explanation: first bring the 5n down then multiply -3x4n gives you -12 and multiply 5x1 that gives you 5 so you would write (5n−12n)−3
then remove the parentheses combine like terms like 5 and 12 are alike because of the n's that means subtract because of the - sign 5-12 which gives you -7 and then you bring down -3 because it's outside the parentheses and that's the answer.

Adam drove 918 miles on 27 gallons of fuel. at this rate, how many gallons of fuel would it take to drive 510 miles.
Answer: 15 gallons
Step-by-step explanation:
Here you are going to want to set up a proportion. 918 miles per 27 gallons = 510 miles per x gallons
918/27 = 510/x
Cross multiply and you get 918x = 13770
and you get x = 15
Or you could do 918 miles / 27 gallons = 34 miles / gallon
and divide the 510 miles of distance by how many miles per gallon, so
510 / 34

Manolo says that the solution of the equation g squared equals 36 is g = 6 because 6*6 = 36. Is Manolos reasoning complete? Explain.
Answer: No. Manolo forgot to include that the opposite of squaring a number is square rooting. If you take the square root of 36, you get 6. When you square a number, you multiply it by itself, which is what Manolo did. He multiplied 6 by itself and got the answer of 36.
Step-by-step explanation: Hope this helps!
The Manolos reasoning is not complete because the quadratic equation has two roots and the roots are 6 and -6.
What is a quadratic equation?Any equation of the form [tex]\rm ax^2+bx+c=0[/tex] where x is variable and a, b, and c are any real numbers where a ≠ 0 is called a quadratic equation.
As we know, the formula for the roots of the quadratic equation is given by:
[tex]\rm x = \dfrac{-b \pm\sqrt{b^2-4ac}}{2a}[/tex]
The question is incomplete.
The complete question is in the picture, please refer to the attached picture.
It is given that:
A quadratic equation:
g² = 36
Manolo says that the solution of the equation g squared equals 36 is g = 6 because 6×6 = 36
As we know, the quadratic equation has two roots.
To solve the quadratic equation we can use the identity:
a² - b² = (a + b)(a - b)
g² = 36
g² - 36 = 0
g² - 6² = 0
(g + 6)(g - 6) = 0
g + 6 = 0 ⇒ g = -6
g - 6 = 0 ⇒ g = 6
Thus, the Manolos reasoning is not complete because the quadratic equation has two roots and the roots are 6 and -6.

What is the midpoint m given q(-2, -4) and R(6, 10)
Answer:
(2,3)
Step-by-step explanation:
Answer:
(2, 3)
Step-by-step explanation:
The formula for midpoint is: M = [tex]\frac{(x_{1}+x_{2} )}{2} , \frac{(y_{1} + y_{2}) }{2}[/tex]
Measure the distance between the two end points, and divide the result by 2. This distance from either end is the midpoint of that line. Alternatively, add the two x coordinates of the endpoints and divide by 2. Do the same for the y coordinates.
