The amount of money in the account after 18 years will be $449.5.
What are congruent triangles?If two triangles have the same size and shape they are called congruent triangles. If we flip, turn or rotate one of two congruent triangles they are still congruent. If the sides of two triangles are the same then the triangles must have the same angles and therefore must be congruent.Given is a parallelogram as shown in the image.
In order to prove ABCD as a parallelogram, we can prove ΔABE and ΔCDE congruent to each other by Angle - Angle - Side congruent property as -
∠BAE = ∠DCE {Alt. int. angles}
∠ABE = ∠CDE {Alt. int. angles}
AB = CD {Given}
Therefore, she can prove ABCD as a parallelogram by proving -
ΔABE ≅ ΔCDE using AAS criteria.

A cylindrical well has a radius of 10 feet and a height of 15 feet. What volume of water will it take to fill the well?
Answer:
volume = 4710 ft³
Step-by-step explanation:
base area = πr² = (3.14)(10²) = 314 ft²
volume = base area x height = 314 x 15 = 4710 ft³

Hi There Answer Nonlinear Association
Step-by-step explanation:
State whether segments of the given lengths can be side of a right angle triangle.
a=7, b=24, and C=25.
Show working to support your answer. *
2 Points
Given:
In a triangle,
[tex]a=7,b=24,c=25[/tex]
To find:
Whether the given segments are the sides of a right triangle or not.
Solution:
In a right triangle the square of largest side is equal to the sum of squares of two smaller side.
[tex]c^2=a^2+b^2[/tex] (Pythagoras theorem)
Three sides are [tex]a=7,b=24,c=25[/tex]. Here, 25 is the largest side.
[tex]25^2=625[/tex]
Now, the sum of squares of two smaller sides is:
[tex](7)^2+(24)^2=49+576[/tex]
[tex](7)^2+(24)^2=625[/tex]
[tex](7)^2+(24)^2=25^2[/tex]
Since the sum of squares of two smaller side is equal to the square of largest side, therefore the given segments are the sides of a right triangle.

Step-by-step explanation:
find the gradient of the line segement between the points (0,-6) and (2,-16)
answer = 5
Slope, sometimes referred to as gradient in mathematics, is a number that measures the steepness and direction of a line, or a section of a line connecting two points, and is usually denoted by m. Generally, a line's steepness is measured by the absolute value of its slope, m. The larger the value is, the steeper the line. Given m, it is possible to determine the direction of the line that m describes based on its sign and value:
A line is increasing, and goes upwards from left to right when m > 0
A line is decreasing, and goes downwards from left to right when m < 0
A line has a constant slope, and is horizontal when m = 0
A vertical line has an undefined slope, since it would result in a fraction with 0 as the denominator. Refer to the equation provided below.
Slope is essentially change in height over change in horizontal distance, and is often referred to as "rise over run." It has applications in gradients in geography as well as civil engineering, such as the building of roads. In the case of a road the "rise" is the change in altitude, while the "run" is the difference in distance between two fixed points, as long as the distance for the measurement is not large enough that the earth's curvature should be considered as a factor. The slope is represented mathematically as:
m =
y2 - y1
x2 - x1

PLEASE HELP ME
Answer:
6Step-by-step explanation:
Plot the points and connect in pairs.
We got a right triangle.
The legs have the length:
1 - (-2) = 3 units and1 - (-3) = 4 unitsThe area of the triangle is:
A = 1/2bh A = 1/2*3*4 = 6 square unitA new field has a perimeter of 220 m and a width of 62 m. A bag of canola seed will cover 185 m2 of ground. How many bags of canola seed are needed to seed the new field?
52
16
53
17
Answer:
17
Step-by-step explanation:
Assuming the field is a rectangle, the perimeter is found through the equation:
[tex]P = 2l + 2w[/tex]
Since we know the perimeter and width, we can substitute and solve for the length.
[tex](220) = 2l + 2(62)\\220 = 2l + 124\\96 = 2l\\l = 48\\[/tex]
Using the length and width, we can find the area.
[tex]A = lw\\A = (48)(62)\\A = 2976[/tex]
The area is 2976 squared meters. We divide by the area a bag of canola seed can cover and round up if necessary to find the total number of bags.
[tex]n = 2976 / 185\\n = 16.09[/tex]
Because we need a whole bag in order to cover for the decimal area, we round up to 17 bags.

The perimeter of a rectangle is represented by the expression 6x + 4. If the width of the rectangle is represented by the expression x – 1, which expression represents the length? 4x + 6 4x – 6 2x + 3 2x + 6
Answer:
2x + 3
Step-by-step explanation:
two sides measure (x-1) which gives 2(x-1) or 2x - 2
subtract 2x - 2 from 6x + 4 to get 4x + 6
4x + 6 represents twice the length so divide it in half to get:
2x + 3
Answer:
The perimeter of a rectangle is represented by the expression 6x + 4. If the width of the rectangle is represented by the expression x – 1, which expression represents the length?

What is circle?A circle is a closed two-dimensional figure in which the set of all the points in the plane is equidistant from a given point called “centre”. The perimeter around the circle is known as the circumference.
here, we have,
we know that,
A secant is a line which intersects a circle at exactly two different points and leaves a chord on joining those two points.
again, we know,
A chord is a line which which terminates on the two different points on the circle.
and, we have,
Radius is the line joining the center to any of the point on the circle.
we know,
Tangent is a line which crosses from the outer periphery of the circle touching at any of its one point.
we get,
Thus the secant in the given diagram is clearly none other than XY.
Hence, The solution is : D. XY, is of the segments below is a secant.

Answer:
[tex]30 + 0.05x < 60[/tex]
The number of texts she can have is less than 600.

Write an inequality to represent the # of texts she can have?
It has to be under 60, so:
[tex]C(x) < 60[/tex]
[tex]30 + 0.05x < 60[/tex]
The solution is:
[tex]0.05x < 30[/tex]

148.877 cubic meters.
Step-by-step explanation:
To find the volume of a cube, multiply the side length by itself 3 times (x^3).
Like this,
5.3 ⋅ 5.3 ⋅ 5.3 = 148.877
148.877 is the product.
Therefore, 148.877 is the volume of this cube.

we have to figure out what "?" equals
120*40= 4800
divide 4800 by 100 becuase that is the maximum percentage
4800/100= 48

All the triangles have 180° total angle measurement.
First question:
114 + 37 + x = 180°
151 + x = 180
x = 180 - 151
x = 29°
Second question:
93 + 46 + x = 180
139 + x = 180
x = 180 - 139
x = 41°
Answer:
In the first question x=29 Because the interior of a triangle adds up to 180.So you will add 114+37=151 , 180-151=29
The second question 93+46=139
180-139=41
x=41
Factor the following trinomials. Place each factor in its own blank. You do NOT need to put
parenthesis, just put one binomial (WITHOUT SPACES) into each blank.
X^2+ 13x + 36
Answer:
(x+9)(x+4)
Step-by-step explanation:
We wish to factor x²+13x+36 into the form of (x+p)(x+q) where p+q=13 and pq=36.
Factors of 36: 1, 2, 3, 4, 6, 9, 12. 18, 36
Notice that 9+4=13 as 9*4=36, which satisfies the values of p and q
This means x²+13x+36 can be factored into (x+9)(x+4)
