a set of two concentric circles is shown above. What is the area of the shaded portion above?
Answer:
The answer is "[tex]44 \ m^2[/tex]"
Step-by-step explanation:
[tex]R=4.5 \ m \\\\r=2.5\ m\\\\[/tex]
The area between two concentrated circles via an exterior circle radius R and an internal circle
[tex]r =\pi(R^2-r^2)[/tex]
The region, therefore, consists of two concentrated circles with radii of 4.5 m and 2.5 m.
[tex]r=\pi(4.5^2 -2.5^2)\\\\[/tex]
[tex]=\frac{22}{7} (20.25-6.25) \\\\ =\frac{22}{7} (14) \\\\=22 \times 2 \\\\ =44 \ m^2[/tex]

Two times the sum of a and b
A. 2(a + b)
B. 2 + ab
C. 2ab
D. 2(a/b)
Answer:
Option A
Step-by-step explanation:
That is your answer
Answer:
a) 2(a+b)
Step-by-step explanation:
the sum of 2 numbers (or more) is always addition
so the sum of a and b would be (a+b)
then, 2 times of a and b;
2(a+b)
^the times sign between the bracket and the 2 isnt needed, whenever there is a bracket and a number next to it, it is automatically a multiplication.
Sana's mother bought produce for Sunday dinner. She bought one more pound of peaches than of tomatoes. She bought 3 times as many pounds of tomatoes than pounds of mushrooms. If peaches cost $6 per lb, tomatoes cost $3 per lb, and mushrooms cost $10 per lb, how many of each did Sana's mother buy for $80?
Please explain how you got the answer like the steps and please dont link any files
1(Identifying):
Tomatoes-x--$3 per lb
Mushrooms- 1/3 x-- $10 per lb
Peaches- x+1-- $6 per lb
2(Equation):
3x+6(x+1)+1/3x*10=80
3x+6x+6+10/3 x=80
12 1/3 x= 74
x=74÷(12+1/3)
Step 3(Final Equations):
74*3/37=6=tomatoes
Meaning...
6+1=7=Peaches
6/3=2= mushrooms
Answer:
7 lb of peaches, 6 lb of tomatoes, and 2 lb of mushrooms
Answer:
7 lb of peaches, 6 lb of tomatoes, and 2 lb of mushrooms

Factor each polynomial using the Greatest Common Factor.
Answer:
–9(3x³ – 8x + 9)
Step-by-step explanation:
–27x³ + 72x – 81
The above equation can be factorised as follow:
–27x³ = –3 * 3 * 3 * x * x * x
72x = 2 * 2 * 2 * 3 * 3 * x
–81 = –3 * 3 * 3 * 3
Common factor = 3 * 3
Greatest common factor = 9
Thus,
–27x³ + 72x – 81 = 9(–3x³ + 8x – 9)
–27x³ + 72x – 81 = –9(3x³ – 8x + 9)

In a right triangle, angle φ has a tangent value of 1.40. The side adjacent to angle φ has a length of 9.0 inches. What is the length of the side opposite angle φ?
a. 6.4 inches
b. 12.6 inches
c. 9.1 inches
d. 54.4 inches
Answer:
b) 12.6 inches
Step-by-step explanation:
tangent is the ratio of the side opposite over adjacent, so if we let x= length of the opposite side, 1.40=x/9, x=12.6 inches
b) 12.6 inches

Find (a) PQ to the nearest tenth and (b) the coordinates of the midpoint of __ pq.
Answer:
a) 5units
b) (4.5, 4)
Step-by-step explanation:
Let the coordinate of P and Q be P(3, 2) and Q(6, 6)
PQ can be gotten using the distance formula;
PQ =√(6-2)²+(6-3)²
PQ = √4²+3²
PQ =√16+9
PQ =√25
PQ = 5units
Midpoint M is expressed as;
M(X, Y) = {(x1+x2)/2, y1+y2/2}
X = x1+x2/2
X = 3+6/2
X= 9/2
X = 4.5
Similarly;
Y = y1+y2/2
Y = 2+6/2
Y = 8/2
Y = 4
Hence the midpoint of PQ is (4.5, 4)

Step-by-step explanation:
What is the theoretical probability of rolling a number less than 5? Write the fraction, decimal and percent.
Given:
Rolling a fair dice.
To find:
The theoretical probability of rolling a number less than 5.
Solution:
The possible numbers of rolling a dice are 1, 2, 3, 4, 5, 6.
Total outcomes = 6
Numbers less than 5 are 1, 2, 3, 4.
Favorable outcomes = 4
Now, the theoretical probability of rolling a number less than 5 is:
[tex]\text{Probability}=\dfrac{\text{Favorable outcomes}}{\text{Total outcomes}}[/tex]
[tex]\text{Probability}=\dfrac{4}{6}[/tex]
[tex]\text{Probability}=\dfrac{2}{3}[/tex]
In decimal form, it can be written as:
[tex]\text{Probability}\approx 0.67[/tex]
In percentage form, it can be written as:
[tex]\text{Probability}=\dfrac{2}{3}\times 100[/tex]
[tex]\text{Probability}\approx 66.67%[/tex]
Therefore, the theoretical probability of rolling a number less than 5 in the fraction, decimal and percent are [tex]\dfrac{2}{3}, 0.67[/tex] and [tex]66.67\%[/tex] respectively.

Solve the equation for all values of x in simplest form:
(x + 1)^2 = 25
Answer:
x =4, x = -6
Step-by-step explanation:
1. Square root the whole equation on both sides
2. You get x+1 = ±5 as the answer.
3. Simplify that to get x = 4 and x = -6.
4. This equation is a quadratic equation, so you should get 2 answers.
Answer:
x=6,−4
Step-by-step explanation:
1.Take the square root of each side of the equation to set up the solution for x
2.Remove the perfect root factor x−1 under the radical to solve for x.
3. Simplify the right side of the equation.
4. The complete solution is the result of both the positive and negative portions of the solution.
5. You get your answer!
x=6,−4

Is (x+4)^2 equivalent to 2x^2+8x+8? Explain or show your reasoning.
answer: no because they have different x values
(x + 4) 2 —> 2x + 8
2 x 2 + 8x + 8 —> 8x + 12
teachers response:
Your answer is correct in that they are not equivalent. But I need you to show me what (x+4)^2 equals. First, you would write it this way: (x+4) (x+4). Now, multiply these binomials…what do you get?

The expression (x + 4)² is not equivalent to the expression 2x² + 8x + 8.
What is an equivalent?The equivalent is the expression that is in different forms but is equal to the same value.
The definition of simplicity is making something simpler to achieve or grasp while also making it a little less difficult.
The expression is given below.
⇒ (x + 4)²
Simplify the expression, then we have
⇒ (x + 4)²
⇒ (x + 4)(x + 4)
⇒ x² + 8x + 16
Thus, the expression (x + 4)² is not equivalent to the expression 2x² + 8x + 8.

Missy and Bill were asked to evaluate the expression -3(-2 + 5).
Answer:
-9
Step-by-step explanation:
Answer:
-9
Step-by-step explanation:
using BODMAS, our mathematical operation begins with the bracket.
it implies that from -3(-2+5), we solve the bracket.
-2+5=3
then our mathematical operation is the 'of' operation.
it implies that -3(3) = -9

plz help me find the area of the kite
Answer:
250 cm squared
Step-by-step explanation:
The formula for an area of a kite is:
A=pq/2
--------
p = 20 and q = 25
Multiply the two together (20 × 25)
Then divide by 2 (500 ÷ 2)
Then you get your answer (250)
Whenever you find the area, be sure to add the ² symbol or squared, or else it will be wrong.
