Parallelogram ABCD is a rhombus. Side BC = 5cm and segment AO = 3.8cm
What is the area of ABCD?
What is the length of diagonal BD?
The area of the rhombus ABCD is 24.7 cm².
The length of diagonal BD is 6.5 cm.
What is the area of a rhombus?A rhombus have equal four sides and the diagonals of the rhombus divides it into four equal right triangles. The area of the rhombus is the sum of individual areas of the four right triangles.
The hypotenuse side of the right triangle = side of the rhombus = BC = 5 cm
One of the legs of the right triangle = AO = OC = 3.8 cmLet the second leg of the right triangle = OB = OD = xThe second leg of the right triangle is calculated as follows;
[tex]x^2 + 3.8^2 = 5^2\\\\ x^2 = 5^2 - 3.8^2 \\\\ x^2 = 10.56\\\\ x = \sqrt{10.56} \\\\ x = 3.25 \ cm[/tex]
The area of one right triangle of the rhombus is calculated as follows;
[tex]A = \frac{1}{2} (3.8)(3.25)[/tex]
The area of the rhombus ABCD is calculated as follows;
[tex]A = 4 \times \frac{1}{2} (3.8)(3.25)\\\\ A = 24.7 \ cm^2[/tex]
The length of diagonal BD is calculated as follows;
[tex]BD = OB \ + \ OD\\\\ BD = x \ + \ x\\\\ BD = 3.25 \ cm \ + \ 3.25 \ cm\\\\ BD = 6.5 \ cm[/tex]

(8c + 2)(5c-7)
Answer:40c^2-46c -14
Step-by-step explanation:
(8c+2)*(5c-7)
8c*(5c-7)+2(5c-7)
40c^2-56c+10c-14
40c^2-46c-14
Answer:
(8c + 2)(5c-7) = 40c²-46c-14Explanation:
(8c + 2)(5c-7) = 40c²-56c+10c-14

Discount 75%, Sale Price $74.75, Original Price-?
Answer:
You will pay $18.69 for a item
Step-by-step explanation:
if you buy an item at $74.75 with 75% discount, you will pay 74.75 - 56.0625 = 18.69 dollars.
Answer:
$299
Step-by-step explanation:
The discount is 75%, so the sale price represents 25% of the original price.
25% : $74.75
(multiply both sides by 4 to get 100%)
100% : $299

In a class of students, the following data table summarizes how many students have a brother or a sister.
We have to determine the probability that a student chosen randomly from the class has a sister.
What is the formula for probability?The probability is the ratio of the number of favorable outcomes to the total outcomes in that sample space. It is expressed as, Probability of an event P(E) = (Number of favorable outcomes) ÷ (Sample space).
Therefore the probability is 5/30 chance of it happening.

The first sequence rule is add 5 starting from 20. The second sequence rule is subtract 7 starting from 56. What is the first number that appears in both sequences?
25
28
42
35
Answer:
35
Step-by-step explanation:
The first number that appears in both sequences is 35.
What is mean by Subtraction?Subtraction in mathematics means that is taking something away from a group or number of objects. When you subtract, what is left in the group becomes less.
Now, The first sequence starts with 20 and adds 5 each time, so the first few terms are:
20, 25, 30, 35, 40, 45, 50, 55, 60, ...
And, The second sequence starts with 56 and subtracts 7 each time, so the first few terms are:
56, 49, 42, 35, 28, 21, 14, 7, 0, ...
Hence, Looking at these lists, we can see that the first number that appears in both sequences is 35.
This is the fifth term in the first sequence as,
⇒ 20 + 5 + 5 + 5 + 5 = 35
And, the fourth term in the second sequence is,
⇒ 56 - 7 - 7 - 7 - 7 = 35
Hence, the first number that appears in both sequences is 35.

Enter your answer, as an exact value, in the box.
Answer:
y=2√3, or 3.46410161513
Step-by-step explanation:
The smaller triangle is a right isosceles triangle, so the other side is also √2. To figure out it’s hypotenuse, you can use the Pythagorean theorem.
√2²+√2²=c²
2+2=c²
4=c²
√4=c
c=2
Now that we know that value, we can look at the bigger triangle. It is a 30-60-90 triangle, which has special properties.
Y would equal the two of the base times the square root of three.
y=2√3, or 3.46410161513
The value of the y is 2√3 if the value of hypotenuse in the triangle with 60-degree angles is 2
What is a right-angle triangle?It is a triangle in which one of the angles is 90 degrees and the other two are sharp angles. The sides of a right-angled triangle are known as the hypotenuse, perpendicular, and base.
From the sin ratio in the triangle with angle 45 degree
Sin45 = √2/x
x = 2
From the triangle with angle 60 degree
y/2 = tan60
y = 2√3
Thus, the value of the y is 2√3 if the value of hypotenuse in the triangle with 60-degree angles is 2

6>w/-2 solve the inequalities
Answer:
w>-12
Step-by-step explanation:
6>w/-2 (Given)
6>-w/2 (Rewrite)
12>-w (Multiply both sides by 2)
-12<w (Remember to flip the sign when dividing or mulitplying by a negative)
w>-12 (Rewrite with w in front)
Therefore, w>-12 is the solution to the inequality.
Answer:
w>-12
Step-by-step explanation:
First, you you need to get rid of the -2 in w/-2 by multiplying -2 by both sides like this.
(-2)6>w/-2(-2)
Then you simplify it like this:
-12>w
However, since you multiplied/divided with a negative, you switch the inequality sign like this:
w>-12
