ABDE is an isosceles trapezoid. Name one pair of congruent triangles that could be used to show that the diagonals of an isosceles
trapezoid are congruent.
9514 1404 393
Answer:
ΔABE, ΔBADΔAED, ΔBDEStep-by-step explanation:
Each diagonal divides the figure into two triangles. Either could be used with its counterpart to show congruence of the diagonals.
ΔABE and ΔBAD, orΔAED and ΔBDESulins savings is 75% of Meifens saving. if Sulin save $300, how much does Meifen save?
A) $225
B) $425
C) $325
9514 1404 393
Answer:
D) $400
Step-by-step explanation:
We are given the relations ...
s = 0.75m
s = 300
Then we can find m by equating the expressions for s:
0.75m = 300
m = 300/0.75 = 400
Meifen's savings is $400.

If 2a = 3b, and 4a - 7 = 2b + 9. what is the value of a?
Answer:

Step-by-step explanation:
slove each system of equations using graphing, substitution or elimination. y=2x-3 y=2x+3
y=2x-3
y=2x+3
Since the both expressions 2x-3 and 2x+3 are equal to y, set them equal to each other forming an equation in x.
2x-3=2x+3
Cancel equal terms on both sides of the equation
-3=3
The statement is false for any value of x and y , so there is no solution

The coach took a digital photo of the new cycling team bike. She sent a 4 cm-by-6 cm photo to each team
member.
1. If the photo were enlarged to 150% of its original size, what would be its new length (long side)?
9
2. Suppose you want to make a 2 cm-by-3 cm copy of the original photo.
What percent should you use?
50%
3. What will be the measurement for each angle in the smaller photo?
Answer:
1. 9 cm
2. 50%
3. Assuming the photo is a rectangle, the answer would be 90 degrees on every angle (in a dilation, angle measurements are congruent).
Step-by-step explanation:
1. The long side is clearly the 6 cm side. multiply it by 1.5x (150%) and you get 9.
2. 2 is 50% of 4 and 3 is 50% of 6.
3. Assuming the photo is a rectangle, the answer would be 90 degrees on every angle (in a dilation, angle measurements are congruent).

Step-by-step explanation:
Vary the scale factor n from values less than 1 to values greater than 1. How do the points in the resulting images differ from the corresponding points on the preimage? Describe the general location of the points relative to the center of dilation. What happens to the logo of the sailboat as you vary the scale factor?
PLATO
Answer: For values of n < 1, all the points on the image move closer to the center of dilation and the logo shrinks. For values of n > 1, all the points on the image move farther from the center of dilation and the logo expands.
Step-by-step explanation: PLATO sample answer. hope it helps :)
Answer:
For values of n < 1, all the points on the image move closer to the center of dilation and the logo shrinks. For values of n > 1, all the points on the image move farther from the center of dilation and the logo expands.

9. What is the value to the solution for the system of equations y = -5X-9 and y = 2x + 5.
9514 1404 393
Answer:
(x, y) = (-2, 1)
Step-by-step explanation:
Equate the two expressions for y.
-5x -9 = 2x +5
-14 = 7x . . . . . . . .add 5x-5
-2 = x . . . . . . . . . divide by 7
Then ...
y = 2(-2) +5 = 1
The solution is (x, y) = (-2, 1).
Please help me it would be AMAZING if you can!!!!

Find the measures of the sides of triangle JKL, then classify it by its sides J(-3, 2), K(2,6), L(8, -1)
Given:
The vertices of the triangle JKL are J(-3, 2), K(2,6), L(8, -1).
To find:
The measures of the sides of triangle JKL and classify it by its sides.
Solution:
Distance formula:
[tex]d=\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}[/tex]
Using distance formula, we get
[tex]JK=\sqrt{(2-(-3))^2+(6-2)^2}[/tex]
[tex]JK=\sqrt{(2+3)^2+(4)^2}[/tex]
[tex]JK=\sqrt{(5)^2+(4)^2}[/tex]
[tex]JK=\sqrt{25+16}[/tex]
[tex]JK=\sqrt{41}[/tex]
Similarly,
[tex]KL=\sqrt{\left(8-2\right)^2+\left(-1-6\right)^2}=\sqrt{85}[/tex]
[tex]JL=\sqrt{\left(8-\left(-3\right)\right)^2+\left(-1-2\right)^2}=\sqrt{130}[/tex]
Now,
[tex]JK^2+KL^2=(\sqrt{41})^2+(\sqrt{85})^2[/tex]
[tex]JK^2+KL^2=41+85[/tex]
[tex]JK^2+KL^2=126[/tex]
[tex]JK^2+KL^2\neq JL^2[/tex]
Since, measure of all sides are different and sum of squares of two smaller sides is not equal to the square of largest side, therefore the triangle is scalene triangle.

In 2020, a town was recorded as having a population of 10,000 and is predicted to grow at 5% every year. What will be the population in 2035, to the nearest whole number? *
Answer:
20789
Step-by-step explanation:
The equation of exponential growth is y=A(1+r)^t
A=10,000
r (rate)=0.05 (5% as a decimal)
t (time)=15 (2035-2020=15)
y=10,000(1+0.05)^15
y=20789.2817
you can't have part of a person, so y=20789
out of the 4, which is the solution?
Answer:
x=0
Step-by-step explanation:
You can substitute 2-6y in for x to create
9y +2(2-6y) = 3
9y + 4 -12y = 3
-3y = -1
y=1/3
Then plug in y for x=2 -6y
x= 2-6(1/3)
2-2=x
x=0

Lianne is saving to buy a DVD player that costs 2 1\2 times her weekly allowance. If she spends 3\4 of her allowance on other things, how long will she take to save the money for the DVD player?
Answer:
She will take 10 weeks to save the money for the DVD player
Step-by-step explanation:
Let w = Lianne's weekly allowance.
The DVD player costs 2 1/2 times her weekly allowance, thus
DVD cost = 5/2w
She gets w every week but spends 3/4w on other things, thus the remaining money is
Weekly savings =w - 3/4w = 1/4w
To know the number of weeks needed, we divide the DVD cost by the weekly savings:
[tex]\displaystyle N = \frac{\frac{5}{2}}{\frac{1}{4}}[/tex]
Operating:
[tex]\displaystyle N = \frac{5}{2}*\frac{4}{1}[/tex]
N = 10
She will take 10 weeks to save the money for the DVD player
