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.

Answer:

It is the second triangle.

Step-by-step explanation:

This is because the area of the square is given as 25^2 as the perpendicular, 144^2 as the base, and the hypotenuse is 169^2.

Length of the perpendicular = 5^2 (Because 25^2 / 5^2)

Length of the base = 12^2

Length of the hypotenuse = 13^2

So, the Pythagoras theorem is,

=> [tex]H^{2} = P^{2} + B^{2}[/tex]

=> [tex]13^{2} =12^{2} +5^{2}[/tex]

This is true, because, 13*13 = 12*12 + 5*5

=> 169 = 144 + 25

=> 169 = 169

Answer:

a=15

Step-by-step explanation:

Pythagorean Theorum says that a²+b²=c², so if we square b and c, subtract b² from c², and then square root that answer, it will equal a.

a²+8²=17²

8²=64

17²=225

225-64=225

√225=15

Answer:

2x + 5y = 7

Step-by-step explanation:

Here, 2x = 7 - 5y is given

The Standard form of equation is

Ax + By = C

Here, Ax = 2x; By = -5y; C = 7

Now, we get

2x = 7 - 5y

2x + 5y = 7

Here we get Ax = 2x; By = 5y; C = 7

Thus, The Standard form of equation is

2x + 5y = 7

Answer:

C: 13cm

Step-by-step explanation:

Given;

length of the rectangle, L = (x + 4) cm

width of the rectangle, W = [tex]\frac{2}{4}x[/tex] cm

perimeter of the rectangle, P = 35 cm

The perimeter of a rectangle is given as;

P = 2(L + W)

Substitute the givens;

[tex]35 = 2[(x+ 4) + \frac{2x}{4} ]\\\\35 = 2[\frac{6x}{4} +4]\\\\35 = 3x+8\\\\3x = 27\\\\x = \frac{27}{3}\\\\x = 9[/tex]

Then, L = (x + 4) cm

L = (9 + 4) cm

L = 13 cm

Therefore, the length of the rectangle is 13 cm

Answer:-5

Step-by-step explanation:

You need to distribute on both sides so u get

9c-15=20-2c

Move variable to left side and change the sign

-9c+2c-15=20

Move constant to right side and change the sign

-9c+2c=20+15

Connect like terms

-7c=35

Divide

C=-5

Answer:

x=2

Step-by-step explanation:

4(x-1) = 2(6-2x)

x=2

Answer:

x=2

Step-by-step explanation:

4(x-1)=2(6-2x)

4x-4=12-4x

Add 4 to both sides

4x=16-4x

Add 4x to both sides

8x=16

Divide by 8 on both sides

x=2

Answer:

433.4

Step-by-step explanation:

Height will be (14/2)/tan36 which is 9.63, then area for one triangle is 1/2*hb which is .5*9.63*7 is 43.34, times 10 you get 433.4

Answer:

[tex]\dfrac{3}{11}[/tex]

Step-by-step explanation:

Given that:

A drawer contains 6 pink and 5 yellow gloves.

Two gloves are randomly drawn without replacement.

To find:

The probability that the two gloves drawn are both pink.

Solution:

First of all, let us have a look at the formula for Probability of an event E:

Formula for probability of an event E can be observed as:

[tex]P(E) = \dfrac{\text{Number of favorable cases}}{\text {Total number of cases}}[/tex]

Here, number of favorable cases are to draw 2 pink gloves out of 6, which is equal to:

[tex]_6C_2 = \dfrac{6\times 5}{2} = 15[/tex]

Here, Total number of cases are to draw 2 gloves out of 11, which is equal to:

[tex]_{11}C_2 = \dfrac{11\times 10}{2} = 55[/tex]

Now, the required probability is:

[tex]P(2\ pink\ gloves) = \dfrac{15}{55}\\\Rightarrow P(2\ pink\ gloves) = \dfrac{3}{11}[/tex]

Therefore, the answer is:

[tex]\dfrac{3}{11}[/tex]

Answer:

The two numbers are 8 and 5.

Step-by-step explanation:

Let consider x and y to be these two numbers.

So;

(x) * (y) = 40 ---- (1)

x + y     = 13 ----- (2)

From (2), let x =  13 - y

Then;

(13 - y) * y = 40

13y - y² = 40

13y - y² - 40 = 0

-y² + 13y - 40 = 0

Multiply through by (-)

y² - 13y + 40 = 0

By factorization;

(y - 8) (y - 5) = 0

y = 8 or  y = 5

CHECK:

8 * 5 = 40

8 + 5 = 13

Therefore, the two numbers are 8 and 5.

Answer:

10w = 70-40

Step-by-step explanation:

To get to $70, Kristi has to work 10w. She has already earned $30 and needs to earn the remaining in 10w. Thus,

10w = 70-30

10w = 40

w = 4

She needs to work for 4 more weeks to buy the bike.

Answer:

X-Intercept: (-8,0)

Y-Intercept (0, -6)

Step-by-step explanation:

The x intercept is where the line intercepts with the line where y is 0, which is the dark horizontal line on the graph. The y intercept is founf the same way instead on the dark vertical line where x is 0.

Answer:

This relation is a function.

Step-by-step explanation:

This relation is a function because a there should be no repeating x-coordinates in the relation for it to be a function and that is exactly what happens in this relation.

Answer:

It is a function.

Step-by-step explanation:

no two different outputs, y, have the same input, x, meaning it passes the vertical line test.

2nd option: 0.07

Step-by-step explanation:

100% in decimal form is 1.00. S0, 7 is really 0.07. Hope this helps. Mark brainliest if it does!

The expression which represents the amount of tax on a t-shirt that cost x dollars, if tax is 7% is 0.07x.

The percentage is defined as a given amount in every hundred. It is a fraction with 100 as the denominator percentage is represented by the one symbol %.

The percentage is just like the amount of that value but between 1 to 100 and it is very useful to predict for example if you say 678 then we have to know about the full number also but if you say 80% then it becomes clear.

Given that,

Cost of t-shirt = x dollars

Tax is 7% which means tax is 7% of the cost of the t-shirt

7% of x ⇒ 7/100 × x = 0.007x

Hence "The expression which represents the amount of tax on a t-shirt that cost x dollars, if tax is 7% is 0.07x".

Answer:

-25 °F

Step-by-step explanation:

First, we would be multiply 3 by 5 to find the number we would be subtracting from the original

3 * 5 would give us 15

Then we subtract -10 by 15 and get -25 °F

The temperature at 1:00 PM would be -25 °F

Answer:

675

Step-by-step explanation:

8%=$50

Answer:

$675

Step-by-step explanation:

Since tax is an added 8% you are in sense paying for 100% of the DVD and 8% for tax, or 108% of the DVD player. Now convert percent to decimals by dividing by 100 to get 1.08. Now you can multiply 1.08 x $625 and get $675
