find the areas of the trapezoids

Answers

Answer 1

Answer:

A = 7.5in^2

Step-by-step explanation:

Your a (base) is 4, which is A-P.

Your b (base) is 1, which is T-R.

Your h (height) is 3, which is the distance from the bottom of the trapezoid to the top.

Then you plug it into your formula, A = (a + b) x h/2 (A = (4 + 1) x 3/2)

That equals 7.5.

Answer 2

The answer is 7.5 or 7.5in^2.

A pair of equations is shown below:

y = 7x − 8
y = 5x − 2

Part A: Explain how you will solve the pair of equations by substitution or elimination. Show all the steps and write the solution.

Part B: If the two equations are graphed, at what point will the lines representing the two equations intersect? Explain your answer

Answers

Answer:

Part A) If would probably be smart to use substitution because y is already solved for, so we can substitute the value of y as a function of x into the other equation.

y=7x-8

y=5x-2

7x-8=5x-2

+8 +8

-----------------

7x=5x+6

-5x -5x

----------------

2x=6

/2 /2

-----------

x=3

y=7x-8

y=21-8

y=13

Part B) The lines will intersect at point (3, 13)

Step-by-step explanation:

hope this helps

so sorry if this is wrong

did this for hw

Answer:

Step-by-step explanation:

part a:

substitution

7x - 8 = 5x - 2

2x - 8 = -2

2x = 6

x = 3

y = 7(3) - 8 = 21 - 8 = 13

y = 13

Part b.

A bowl has 3 red beads and 7 blue beads. Two beads are selected at random one at a time. First a red bead is drawn and placed on a table. Next a blue bead is drawn.

What is the probability of this event?

Drag and drop the answers into the boxes to complete the sentences.

Answers

The probability that first a red bead is drawn and next a blue bead is drawn is 7/30,and both events are dependent

How to determine the probability?

The distribution of the beads are:

Red = 3

Blue = 7

Total = 10

The probability of selecting the red bead first is:

P(Red) = 3/10

When the red bead is selected, the number of beads becomes 9

So, the probability of selecting a blue bead is

P(Blue) = 7/9

The probability of the event is then calculated using:

P = 3/10 * 7/9

Evaluate

P = 7/30

Hence, the probability of the event is 7/30

Find the measure of angle x in the figure below:

A) 35
B) 47
C) 51
D) 62

Answers

Answer:

The value of y = 62°

and x = 50°

Step-by-step explanation:

=> 57° + y + 61° = 180°

=> 118° + y = 180°

=> y = 180° - 118

=> y = 62°

Now ,

x° + y° + 67° = 180° { sum of angles of a triangle is 180° }

=> x° + 62° + 68° = 180°

=> x + 130° = 180°

=> x = 180° - 130°

=> x = 50°

100 POINTS AND BRAINLY NO LINKS What is the length of the line segment with endpoints (−3, −8) and (10, −8) ?

Answers

Answer:

13 units

given two points: (−3, −8) and (10, −8)

As the y coordinates are same.

use the method:

|x2| + |x1| where (x1, y1), (x2, y2)

Solve:

|10| + |-3|

10 + 3

Answer:

10 units

Step-by-step explanation:

[tex](x_1,y_1)=(-3,-8)[/tex]

[tex](x_2,y_2)=(10,-8)[/tex]

We are supposed to find the length of the line segment with endpoints (−3,8) and (7, 8)

We will use distance formula : [tex]d=\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}[/tex]

Substitute the values :

[tex]d=\sqrt{(10+3)^2+(8-8)^2}[/tex]

[tex]d=\sqrt{100}[/tex]

[tex]d=10[/tex]

Hence the length of the line segment with endpoints (−3,8) and (7, 8) is 10 units
