A coin is flipped 20 times. The coin lands on HEADS 12 times. Write the ratio for landing on heads in fraction and percent form.

Answers

Answer 1

Answer:

12/20

60%

Step-by-step explanation:

A fraction has a numerator and denominator

The numerator is the total number of heads

The denominator is the total number of times the coin was flipped

[tex]\frac{12}{20}[/tex]

To express in percent form, multiply by 100

[tex]\frac{12}{20}[/tex] x 100 = 60%

Answer:

x = 11.4 m

y = 21 m

man's shadow = 9.6 m

Step-by-step explanation:

measure of third angle must be 50 degrees (180 - (40 + 90))

you can take tan50° = 15/y and 'y' will equal approx. 21

to find 'x' you can take tan21° = (21-x) /25 and 21 - x = 25 · tan21°

21 - x = 9.6

-x = -11.4

x = 11.4

man's shadow is the difference of 21 and 11.4, which is 9.6

what is the least perfect squared number that is divisible divisible by

12

16

20

24

NOTE : the first one who answers gets branilast

Answers

The lowest perfect squared number that is divisible by 12,16,20,24 is 3600
1. Let's find the L.C.M
12 = 2×2×3
16 = 2×2×2×2
20 = 2×2×5
24 = 2×2×2×3
The L.C.M is 2×2×2×2×3×5 = 240
2. Now, the L.C.M 240 is not a perfect square.
3.Therefore to obtain a lowest perfect square the given number should be should have another 3 and 5 as the factor.
4. So, multiplying 240 by 15 we, get 3600 which is a perfect square and it can be divided by 12,16,20,24.
5. 3600 is the square of 60.
6.Therefore, the lowest perfect square that is divisible by 12,16,20,24 is 3600

Carlos bought 3 gallons of ice cream for $9.50. Which proportion
can be used to find the cost of 7 gallons of ice cream?

Answer:

Cost of 7 gallon ice cream = 22.167 (Approx.)

Step-by-step explanation:

Given:

Cost of 3 gallon ice cream = $9.50

Find:

Cost of 7 gallon ice cream

Computation:

Cost of 1 gallon ice cream = 9.50 / 3

Cost of 1 gallon ice cream = $3.1667 (Approx.)

So,

Cost of 7 gallon ice cream = 7 x 3.1667

Cost of 7 gallon ice cream = 22.167 (Approx.)

What are the slope and y-intercept of the graph of this equation?
y = 2x - 5

Answers

Answer:

In this equation, y = 2x - 5, it is already in that form and so the cumber in front of the x is the slope (2) and the constant number is the y-intercept (-5) - it's negative because of the minus sign in front of the number. So, the slope is 2 and the y-intercept is -5.

11. X=32

12.Y=40

Step-by-step explanation:

Answer:

7. [tex]a=48[/tex]

8. [tex]b=30[/tex]

9. [tex]c = 188[/tex]

10. [tex]d = 18[/tex]

11. [tex]x = 32[/tex]

12. [tex]y = 40[/tex]

Step-by-step explanation:

Let's do something called cross-multiplication. It's exactly what it sounds like, we multiply the top number with the denominator across the multiplication.

[tex]\frac{33}{a} = \frac{11}{16}[/tex]

[tex]11 a = 33(16)[/tex]

[tex]11a = 528[/tex]

Now we can simplify.

[tex]a=48[/tex]
