PLEASE HELP ON MY LAST GEOMETRY PROBLEM!!
Answer:
area of circle having radius 3
is πr²=π*3²=9π square units
area of circle having radius 2
=πr²=π×2²=4π square units
again
area of big circle having radius [3+2]=5 units
=πr²=π×5²=25π square units
Now
area of shaded region=25π-4π-9π=12π or 37.7square units.
Answer:
12π units² or 37.7 units²
Step-by-step explanation:
Find the area of the 3 circles and subtract the areas of the two smallest ones.
Biggest circle area: π((3(2)+2(2))/2)² = π((6+4)/2)² = π(5²) = 25π units²
2nd Biggest circle area: π(3)² = 9π units²
Smallest circle area: π(2)² = 4π units²
Shaded area: 25π - (9π + 4π) = 25π - 13π = 12π units² or 37.7 units²

help What is the area, in square centimeters, of the trapezoid below?
Answer:
115.15 cm²
Step-by-step explanation:
The area of a trapezoid = 1/2 (b1 + b2)h
Where:
b1 = first base = 8.2 cm
b2 = Second base = 15.3 cm
h = height = 9.8 cm
Hence, Area of the trapezoid =
1/2 (8.2 + 15.3) × 9.8
= 1/2 × (23.5) × 9.8
= 115.15 cm²
Therefore, the area, in square centimeters, of the trapezoid below is 115.15 cm²
Rona was driving on an asphalt road that had a 35 mile per hour speed limit posted. A lrr r deer jumped out from the side of the road causing Rona to slam on her brakes. Her tires left three skid marks of lengths 70 ft., 72ft., and71ft. The road had a drag factor of .78. Her brakes were operating at 95% efficiency. The police gave Rona a ticket for speeding. Rona insisted that she was driving under the speed limit. Who was correct (the police or Rona)
Answer:
The answer is "The cops were correct because the average speed would have been about 39.73 miles per hour as per the calculations."
Step-by-step explanation:
Finding the average skid distance:
[tex]Average=\frac{70+71+72}{3}=\frac{213}{3}=71[/tex]
Calculating the skid:
[tex]S=\sqrt{30 \times D \times f\times n}\\\\[/tex]

Ms. Blue wants to build a garden in her back yard. She first builds a scale model. Find the area of the real garden.
Answer: Hello! I believe your answer would be 162.
Step-by-step explanation: So the formula for Area on a rectangle is WxL. So length will be 9. But if you notice on the scale rectangle the width is the length times two. So the length on the real garden is 18.

Answer: x+(x+1)+(x+2) = 63
This is because x is the smallest number, so x+1 is the next value up, and x+2 is the value after that. The parenthesis are optional. I used them to separate out the three expressions. We can simplify the left side to 3x+3, which means that equation in bold is the same as 3x+3 = 63. So there are few ways we can form the equation.
You have the correct answers for the other boxes:
20+21+22 = 63
Nice work.
20, 21, 22
Step-by-step explanation:
Let x = the smallest integer of the three consecutive ones
(x + 1) = the next consecutive integer after x
(x + 2) = the next consecutive integer after (x + 1)
The sum of these three should add up to 63 so
x + (x + 1) + (x + 2) = 63
This simplifies to
3x + 3 = 63
Solving for x, we get
x = 20
Therefore, the three consecutive integers whose sum add up to 63 are 20, 21 and 22.

(4h + 6)(4h − 7)
16h2 − 52h + 42
16h2 + 4h − 42
16h2 + 52h + 42
16h2 − 4h − 42
Answer:
16h^2-4h-42
Step-by-step explanation:
4h times 4h is 16h^2
4h times -7 is -28h
4h times 6 is 24h
6 times -7 is -42
Combine like terms to get 16h^2-4h-42

Quadrilateral ABCD is a parallelogram such that ∠A=2x and ∠B=x+6. What is the measure of ∠B?
Problem 1
Angles A and B are adjacent in parallelogram ABCD. For any parallelogram, adjacent angles are supplementary.
A+B = 180
2x+(x+6) = 180
3x+6 = 180
3x = 180-6
3x = 174
x = 174/3
x = 58
Use this x value to find angles A and B
angle A = 2x = 2*58 = 116 degrees
angle B = x+6 = 58+6 = 64 degrees
Answer: 64 degrees
================================================
Problem 2
Let y be the measure of the unknown angle that's supplementary to the 42 degree angle. This must mean that,
y+42 = 180
y = 180-42
y = 138 degrees
Answer: D) 138 degrees
The measure of ∠B is 64 degrees.
The angle that is supplement ot the angle 42 degrees is 138 degrees.
What are supplementary angles?
Supplementary angles are angles that sum up to 180 degrees. When two angles sum up to 180 degrees, they are supplementary angles.
Therefore,
Adjacent angles of a parallelograms are supplementary.
Hence,
∠A + ∠B = 180
2x + x + 6 = 180
3x + 6 = 180
3x = 180 - 6
3x = 174
x = 174 / 3
x = 58
Therefore,
∠B = 58 + 6 = 64°
The other angle that is supplement to 42 degrees is as follows;
42 + y = 180
y = 180 - 42
y = 138°

9. For each scenario, would you gather data by using a survey, an experiment, or an observational study? Why?
A) You want to know if playing certain types of music affects the way plants grow.
B) You want to know what kind of plants people prefer to grow in your town.
C) You want to know if using a certain kind of fertilizer will help the dying tree in your yard.
PLEASE PLEASE EXPLAIN WHY
Answer:
A) experiment B) Survey C) observational study
Step-by-step explanation:
A could either be experiment or observation but you are experimenting with different types of music and plants so experiment makes more sense to me.
B is a survey because you are asking a group about a topic and recording the answer which is essentially a survey.
C is an observation because you are checking to see improvement, no improvement, or stays the same ie: meaning you have to observe what happens before and after

Step-by-step explanation:
The given equation is :
[tex]s=ut+\dfrac{1}{2}at^2[/tex]
Where
s is displacement
u is the initial velocity
a is acceleration
t is time
If u = 0, the above equation become,
[tex]s=\dfrac{1}{2}at^2\\\\t^2=\dfrac{2s}{a}\\\\t=\sqrt{\dfrac{2s}{a}}[/tex]

Answer:
$52
Step-by-step explanation:
Given data
Price of blender= $65
Coupon = 20%
Let us find the amount of the coupon
=20/100*65
=0.2*65
=$13
Hence the amount of the coupon is $13
The total price Nathan pays is
=65-13
=$52

Angle E = 37 degreesAngle G = 37 degrees============================================================
Explanation:
Angles E and G are congruent base angles of the isosceles triangle. The base angles are opposite the congruent sides EF = FG
Let x be the measure of angle E and angle G.
Adding all three angles of any triangle always gets us 180 degrees.
E+F+G = 180
x+106+x = 180
2x+106 = 180
2x = 180-106
2x = 74
x = 74/2
x = 37
Angles E and G are 37 degrees each
Answer:
37 degrees for both angles
Step-by-step explanation:
Any triangle is equal to 180 degrees
therefore, 180 - 106 = 74
74 / 2 = 37
I divided by 2 because you need an amount of 2 angles.
Thus, angles m<E and m<G are both equal to 37 degree
To check:
106 + 37 + 37 = 180
