What is the area of the shaded region below?
7 m
30 m
7 m
21 m
Answer:
322.28
A
Step-by-step explanation:
Area of the rectangle
L = 30
W = 21
Area = 30 * 21
Area = 630
Area of the circles
Radius = 7 m
Area = pi r^2
Area = 3.14 * 7^2
Area = 153.86 m^2
Area of both circles = 307.72
Area of the Shaded Region
Area of shaded region = area of the rectangle - area of 2 circles.
Area of Shaded Region = 630 - 307.72
Area of Shaded Region = 322.28

Tory sold 50 balloons for School Spirit Day. He raised $37.50. He wrote this equation to show how much he charged for each balloon.
= 37.50
What mistake did Tory make in writing his equation? What is a correct equation and its solution?
A. He divided b by 50 instead of by 37.50. A correct equation is = 50. Its solution is $1,875.
B. He divided b by 50 instead of dividing 50 by b. A correct equation is = 37.50. Its solution is $1.33.
C. He divided b by 50 instead of multiplying b by 50.A correct equation is 50b = 37.50. Its solution is $0.75.
D. He divided b by 50 instead of setting up a proportion. A correct equation is = . Its solution is $1,875.
Answer:
Answer is C $0.75
Step-by-step explanation:
50b = 37.50
divide both sides by 50
50 cancels out b is by itself.
37.50 divide by 50= 0.75
The mistake Tory made is he divided b by 50 instead of multiplying b by 50. A correct equation is 50b = 37.50. Its solution is $0.75.
What does division mean?Division is a mathematical operation that involves the grouping of a number into equal parts using another number. The sign used to denote division is ÷.
The equation that represents the total amount raised: total balloons sold x cost of one balloon
b x 50 = 37.50
b = 37.50/ 5-
b = $0.75

how do nurses utilize a quadratic equation and example
Answer:
Nurses use the quadratic equation for calculating the dosage of the patients, calculating drip rates, conversion between the systems, drug titration, and more.
Step-by-step explanation:
Nurses with an order to "give 750 mg every 4 hours as needed for pain" may receive 250 mg tablets from the pharmacy, requiring them to calculate the number of pills to administer. They also need to calculate the amount of medicine to give when drawing up liquid medicine for injection. In order to give 7.5 mg must be compared to the vial, which states, "5 mg per cc." Some medication orders require the nurse to calculate the dosage based on the patient's weight.
Quadratic equations are applicable in nursing particularly in the aspect of drug and dosage administration.
Dosage of drugs or other medications usually have units of measurement which are to be administered with respect to factors such as time and weight of the patient. Therefore, the required dosage which will be administered with respect to time and weight can be expressed as a quadratic function.A scenario whereby, a nurse is supposed to administer 20 mg of medication to 5 patients weighing 20 pounds above a certain weight. The stipulated weight can be calculated using a quadratic equation.Therefore, quadratic equations are applicable in nursing particularly in dosage administration.

Answer:
Question 1: 11%
Question 2: 89%
Question 3: 43%
Question 4: 11%
Step-by-step explanation:
Looking at picture 1, we need to find the crossing point between -1.2 and 0.05. That has 0.1056, which is the same as 10.56%. 10.56% rounds to 11%, so C is our answer.
Picture 2 has the same chart, but we just need to find the inverse, since the inequality sign is flipped. 100 - 10.56 is 89.44%, which rounds to 89%, so D is the answer for Picture 2.
Picture 3 has two tables. 0.73 has 76.73% and -0.41 has 34.09%. Subtract 34.09% from 76.73% to get 42.64% That rounds to 43%, so A is the answer.
Picture 4 essentially has the same expression as Picture 2 (only the sign has switched): P(z ≥ 1.25). The meeting point is 89.44%. Now, subtract that from 100 to get 10.56%, which rounds to 11%. C is our answer for Picture 4.

y = x + 9
3x + 8y = -5
PLEASE SHOW WORK!!!
Due TODAY!!!!!
Answer:
x=-45/11
y=10/11
Step-by-step explanation:
y = x + 9 eq 1
3x + 8y = -5 eq 2
Re arranging eq 1
x-y=-9
Now multiply eq 1 with 8
8x-8y=-40 now call as eq 3
Add eq 2 and 3
3x+8y=-5
8x-8y=-40
11x=-45
x=-45/11
put value of x in eq 2 for y
3(-45/11)+8y=-5
-135/11+8y=-5
8y=-5+135/11
8y=(-55+135)/11
8y=80/11
y=(80/11)*(1/8)
y=10/11
Check
3*(-45/11)+8*(10/11)=-5
-135/11+80/11=-5
(-135+80)/11=-5
-55/11 =-5

21 and 22 are complementary angles. The measure of Z1 is 60°. The
measure of 22 is 5(x - 1)º. Find the value of x.
Answer:
The value of x is 7
Step-by-step explanation:
Complementary angles have a sum of 90°, therefore the equation to solve for x is:
∠1+∠2=90°
60°+5(x-1)°=90°
5(x-1)=30°
x-1=6
x=7
So the value of x is 7

Answer:
49
Step-by-step explanation:
Alrighty, PEMDAS, lets get started:
9 + 3(10 ÷ 2) + 5²
So we start with the parenthesis:
10 ÷ 2 = 5
Now we do the exponent:
5² = 25
So we now have:
9 + 3 x 5 + 25
we do multiplication first:
3 x 5 = 15
so we have:
9 + 15 + 25 = 49
So 9 + 3(10 ÷ 2) + 5² = 49

The cost of g gallons of gasoline can be modeled by C(g) = 2.25g
How much would it cost to buy 12 gallons of gasoline?
Answer:
C(g) = 27
Step-by-step explanation:
2.25(12) = 27
You just plug in your g value and solve.
It would cost $27 to buy 12 gallons of gasoline. Substitute the value of g (number of gallons) into the cost function C(g).
In the cost function C(g) = 2.25g, the variable g represents the number of gallons of gasoline we want to buy. We want to find out the cost of buying 12 gallons, so we will replace g with 12 in the equation:
C(12) = 2.25 * 12
Perform the multiplication.
Now, we simply calculate the value of 2.25 * 12:
C(12) = 27
So, the result is 27. It means that it would cost $27 to buy 12 gallons of gasoline using the given cost function C(g) = 2.25g. The cost is calculated by multiplying the number of gallons (12) by the cost per gallon (2.25).
