Answer:
A = 20 degrees
Step-by-step explanation:
Both legs of the triangles are 2x and equal, so we know that the triangle is isoceles. That means both acute angles are equal as well.
In a triangle there are 180 degrees
180 - 140 = 40
40 remainding degrees/ 2 equal angles
A = 20 degrees
Answer:
angle a = 20
Step-by-step explanation:
So like the person above me said
180-140=40
40 divided by 2 is 20

Find the area of the circle that contains the sector described below. Round to the nearest tenth, if necessary.
One sector has an area of 325 square millimeters and an arc measure of 72°.
__ mm2
Answers
If One sector has an area of 325 square millimeters and an arc measure of 72° then the area of circle is 1625 square mm.
What is Circle?A circle is a shape consisting of all points in a plane that are at a given distance from a given point, the centre.
To find the area of circle we have to know the radius of the circle.
We know Area of sector=(θ/360º) × πr²
325=72/360×3.14r²
325=0.2×3.14r²
325=0.628r²
Divide both sides by 0.628
r²=517.51
Area of circle= πr²
=3.14×517.51
=1625 square mm.
Hence, if One sector has an area of 325 square millimeters and an arc measure of 72° then the area of circle is 1625 square mm.

What is the surface are of the cylinder with a height 7ft and radius 3ft?
Answers
Answer:
Total area, including top and bottom: 67.7 ft²
Step-by-step explanation:
The area of the sides (only) is A = (circumference of base)(height of cylinder), and in this case A = 2(3 ft)(3.14), or
approximately A = 18.8 ft²
If you also want the areas of the base and top of the cylinder, perform the indicated calculations:
A (top and bottom) = 2π(3 ft)² = 48.9 ft²
So that the total surface area is (48.9 + 18.8) ft², or 67.7 ft²
1. Three apples, a, and two peaches, p, sell for $1.25.
Five apples and 1 peach sell for $1.50. What is the
cost of one apple?
Answers
Answer:
$0.25
Step-by-step explanation:
You can use systems of equations to solve this.
3a+2p = 1.25
5a+p = 1.5
Multiply the second equation by 2.
3a+2p = 1.25
10a+2p = 3
Subtract the bottom from the top
-7a= -1.75
Divide by -7
a= 0.25
Each apple is $0.25 (in this case, the peach also costs $0.25)

find the measure of angle 7
Answers
Answer:
63°
Step-by-step explanation:
Knowing that opposite angles are equivalent, we can easily say that ∠3 is equivalent to 63°. ∠1 and ∠4 are the complements of the given angle and ∠3, so their measures are also the same and are equivalent to 180°-63°=117°.
Since the two horizontal lines are parallel, ∠6 is equivalent to ∠3, so it too is 63°. Its complements, ∠5 and ∠8, are thus equivalent to the complements of ∠1 and ∠4, and thus they are 117°. Lastly, since opposite angles are equivalent, ∠6 is equivalent to ∠7, and so ∠7 is also 63°.

the distance a plane travels between two cities is 260 miles. The same trip, in miles, traveled by car is approximately 10% greater due to the route traveled. If the car travel at an average rate of 55 miles per hour, approximately, how long will it take the car to travel between the same two cities?
Answers
Answer:
5.2 hours or 312 minutes
Step-by-step explanation:
The plane route has been given as 260 miles.
We're told that the car/road rouge is 10% longer, and that is 260 * 1.1, which is equal to 286 miles.
Now, the car travels at 55 miles per hour, and we're to calculate how long it will take to travel.
Speed = distance / time
Making time the subject of formula, we know that
Time = distance / speed
Time = 286 miles / 55 miles per hour
Time = 5.2 hours, converting to minute, we have 5.2 * 60 = 312 minutes.
The Marching band enters the gym and marches across the gym without turning. Which of these describes the transformation?
A. Dilation
B. Reflection

Transformation involves changing the position of an object.
The transformation in this scenario is translation
From the question, we understand that:
The marching band marches across the gymAnd they did not turnThe above points simply mean that, they moved across the gym in a straight direction.
A movement on a straight line represents translation.

Josie is picking apples. She has 3 identical baskets that she is trying to fill. One basket is 3/5 full, another is 7/10 full, and the last is 2/3 full. What portion of the 3 baskets has Josie filled? Give you answer as a mixed number and as an improper fraction.
Answers
Answer:
1 29/30 full
Step-by-step explanation:
Basket 1 = 3/5 full
Basket 2 = 7/10 full
Basket 3 = 2/3 full
Total = 3/5 + 7/10 + 2/3
= (18+21+20) / 30
= 59/30
= 1 29/30 full
Therefore, the portion of the 3 baskets Josie has filled is 1 29/30

p=c(1+r)^t
p=4,000(1+.04)^t
p=4,000(1.04)^t
p=4,000(1.04)^4
p=4679.43424
p= the population you are solving for
