Find the area of an isosceles triangle with a base length of 10 cm in each of the congruent sides having length of 10 cm.

Answers

Answer 1

Answer:

25√3cm²

Step-by-step explanation:

Area of the triangle = 1/2 * base * height

Base = 10cm

Height is gotten using the pythagoras theorem

h² = 10² - 5²

h² = 100 - 25

h² = 75

h = √75

h = 5√3

Get the area

Area = 1/2 * 10 * 5√3

Area = 25√3cm²

hence the area of the tringle is 25√3cm²

Plz Help The leading brand of cosmetics in the US had about 20% of the total sales in the industry. The total sales were $2.6 billion. What was the leading brands sales? Show your work. I need the shown work, it's an exam.

Answers

Answer:

$0.52 billion

Step-by-step explanation:

Given data

We are given that the total sale in the industry is $2.6 billion

And the leading brand has about 20% of the total sale

Hence the leading brand's sale is

=20/100*2.6

=0.2*2.6

= $0.52 billion

Therefore the leading brand's sale is about $0.52 billion

Giselle spent 7/10 of her money on a book and 10/100 of her money on food. What fraction of her money did she spend altogether?

Answers

Answer:

80/100 or 80%

Step-by-step explanation:

7/10 = 70/100

70/100 + 10/100 = 80/100

Answer:

She spent 80/100 or 8/10 of her money on food.

Step-by-step explanation:

You can multiply 7/10 by 10 to get 70/100, then add it with 10/100. You're finally result would be 80/100. If supposed to be simplifed, choose 8/10

2. Find the area of the regular polygon.
*HINT* - You must solve for the side of the octagon before you can find the area of the figure.

b. What is the area of the figure?

Answers

Answer:

P = 80

A = 480²

Step-by-step explanation:

To solve for the base we use the Pythagorean Theorem

[tex]13^2-12^2=25\\\sqrt{25} =5[/tex]

then we multiply by 2 to get the side length

2x5=10

this is an 8 sided figure with congruent sides so to get the perimeter we multiply 8 and 10

8x10=80 so the perimeter is 80

To find the area of a regular polygon we multiply the apothem (12) and the perimeter (80) and divide by 2

12x80=960

960/2=480

the area is 480²

Can a rhombus be inscribed in a circle? Why or why not?

A.)Yes, any rhombus can be inscribed in a circle, because the consecutive angles of a rhombus are congruent.
B
Yes, a square is the only rhombus that can be inscribed in a circle, because the opposite angles of a square are supplementary

C. No, no parallelogram can be inscribed in a circle, because the opposite angles are not necessarily congruent.

D. No; no rhombus can be inscribed in a circle, because the opposite angles are not necessarily supplementary

Answers

Answer:

b

Step-by-step explanation:

it isn't c because theres a theorem that says that opposite angles in a parallelogram are congruent

it isn't d because if the opposite angles are 90 and 90 they are supplementary

a is correct, but for the wrong reason

A bag holds 6 green, 9 red and 4 blue marbles a marble is selected at random what is the probability of not selecting a red marble?

Answers

Answer:

The probability of not selecting a red marble, P(R)'  = 10/19

Step-by-step explanation:

The probability of an event occurring is equal to the number of ways the required event occurs divided by the number of possible outcomes

The number of ways of an event not occurring is 1 less the probability of the event occurring

The number of green marbles in the bag = 6

The number of red marbles in the bag = 9

The number of blue marbles in the bag = 4

The sum of the marbles in the bag, n = 6 + 9 + 4 = 19

The number of ways of selecting a red marble = 9 ways

The probability of selecting a red marble = 9 ways/19 marbles = 9/19

The probability of not selecting a red marble = 1 - 9/19 = 10/19 = [tex]0.\overline{526315789473684210}[/tex]

The probability of not selecting a red marble P(R)' = 10/19

Answer:

The probability of NOT selecting a red marble is 10/19 (or 52.6%)

Step-by-step explanation:

6 green+ 9 red+ 4 blue = 19 marbles in total. So 19 would be our denominator. The total of marbles that IS NOT red is 10 total (6+4). Now we would put 10 as our numerator. 10/19. We could simplify but 10 and 19 have no common factors. So it would but stay 10/19. Hope this helped
