please please please please help what is the area of trapezoid ABCD enter your answer as a decimal or whole number do not round at any steps help

Answer 1

Answer:

Answer:

A = 62.5

Step-by-step explanation:

I would break this up into two easier cases. the square at the top where three vertices are A,B, and C. and then the triangle for the rest of the area. we can use the distance formula to find the side length of the square.

sqrt((y2-y1)^2 + (x2-x1)^2)

sqrt((5-2)^2 + (-1-3)^2)

sqrt(3^2 + (-4)^2)

sqrt(9 + 16)

sqrt ( 25)

so the area of the square is 5^2 =25

now for the triangle. the formula for the area of a triangle is (1/2)bh.

so we can plug in our b=5, but we need to find h.

we use the distance formula between point A and D to find the distance to be 20, but we have to subtract the 5 we already counted in the area of the square. so the height is 15.

so The triangle has area (1/2)×5×15

37.5.

add the two areas together and we get our answer

25+37.5 = 62.5

Mrs. Matthews drew a hexagon with a perimeter of 60 centimeters on a sheet of paper. She used the photocopier in her office to make copies of her drawings. The length of each side of the hexagons on the photocopies is 1 and 1/2 times the length of each side of the hexagon on the drawing. What is the perimeter in centimeters of each hexagon on the photocopies?A. 40
B. 90
C. 69
D. 150

Answers

B. 90 because original is 60cm so it is 60cm /2 = 30
cm (1/2 of original is 30 cm) so 60cm(original) + 30cm = 90

Tasha sells gift boxes and cookies at her bakery. Gift boxes sell for $26.00 each. Cookies sell for $1.50 each. Tasha would like her total sales to be at least 50.00 from the sale of one gift box and some cookies. Which inequality describes the number of cookies (x) that Tasha needs to sell? Question options:

x ≥ 2

x ≥ 8

x ≥ 16

x ≥ 24

Answers

hi there hope it helps

1 gift box=26 dollar

1 cookie=1.50 dollar
Total amount of money=50 dollar

first she needs to buy a new gift box that is 50-26=24 dollar

then from 24 dollars she needs to buy cookies
you know that

1 cookie = 1.50 dollar
24/1.50=16x ≥ 16

There are 26 students in an algebra class. The number of girls in the class is one less than twice the number of boys. How many boys are in the class.

Answers

g = girls in class

b= boys in class

g = 2b-1

girls + boys =26

g+b=26

substitute g = 2b-1

2b-1 +b =26

combine like terms

3b-1 =26

add 1 to each side

3b -1+1 = 26+1

3b = 27

divide each side by 3

3b/3 = 27/3

b = 9

There are 9 boys

Whats longer 3 hours or 175 minutes

Answers

3 hours is longer than 175 minutes. An hour is 60 minutes long, so just multiply that by 3 and compare your answer to 175.

60 x 3 = 180
180 > 175

Therefore, 3 hours is longer than 175 minutes.

Hope this helps!

3*60=180 minutes
3 hours is longer

What is the value of 60 tens

Answers

The value of 60 tens is 600.

What is the place value?

The value of each digit in a number is known as place value. Every digit in a number has a distinct value depending on where it is located. The value of a digit depends on its position in the number, which might result in a number having two comparable digits with distinct values.

Given that, 60 tens.

Tens is the position two spaces to the left of the decimal point in a number written using the Arabic numeral system.

Here, 60×10

= 600

Therefore, the value of 60 tens is 600.
