The local ice cream shop surveyed their costumers to see wich flavor of ice cream is most popular.125 people chose chocolate as their favorite flavor,wich represents 25% of the costumers surveyed.How many total costumers were surveyed?

Answers

Answer: The total costumers were surveyed = 500

Step-by-step explanation:

Let x = total costumers were surveyed.

Given : 125 people chose chocolate as their favorite flavor, which represents 25% of the costumers surveyed.

25% of x = 125

[tex]\Rightarrow\ \dfrac{25}{100}\times x = 125\\\\\Rightarrow\ \dfrac{1}{4}x=125\\\\\Rightarrow\ x=125\times4\\\\\Rightarrow\ x= 500[/tex]

Hence, the total costumers were surveyed = 500

Layla emptied out her change jar to buy a new binder for school. She found 147 coins consisting of dimes and nickels that totaled $11.65. Write a system of equations that could be used to determine how many dimes, d, and how many nickels, n, Layla had in her change jar.

Answers

Answer:

d + n = 147

0.10d + 0.05n = 11.65

d = 86, n = 61

Step-by-step explanation:

Let

Number of dimes = d

Number of nickels = n

Total coins = 147

Total value = $11.65

d + n = 147 (1)

0.10d + 0.05n = 11.65 (2)

From (1)

d = 147 - n

Substitute d = 147 - n into

0.10d + 0.05n = 11.65

0.10(147 - n) + 0.05n = 11.65

14.7 - 0.10n + 0.05n = 11.65

- 0.10n + 0.05n = 11.65 - 14.7

-0.05n = -3.05

n = -3.05 / -0.05

= 61

n = 61

Substitute n = 61 into

d + n = 147

d + 61 = 147

d = 147 - 61

d = 86

Question 4 of 5
Find the length of side a.

A. 9
B. 34 square root
C. 2
D. 3

Answers

The answer is D.3
You would need to set up the pythagorean theorem
a^2+4^2=5^2
next you would have
a^2+16=25
now subtract 16 from both sides and you are left with
a^2=9
now take the square root of both sides
a=3

how to solve using Substitution or Elimination?
y=3x-1

y=2x+2

Answers

By elimination:

y = 3x - 1

y = 2x + 2

Subtract the second equation from the first

0 = x - 1

y = 2x + 2

Subtract the first equation from the second

0 = x - 1

y = x + 3

Subtract the first equation from the second again

0 = x - 1

y = 4

Subtract x from both sides of the first equation

- x = - 1

y = 4

Divide the first equation by (-1)

x = 1

y = 4

So, the solution is x = 1 and y = 4 {or: (1, 4)}

Answers

Answer:

63 centimeters

Step-by-step explanation:

What we know:

A cricle has a diameter of 20 cm.

To find circumference, use πd or 2πr.

3.14(10 * 2)

3.14(20)

62.8 cm, which rounds to 63 cm.

The sum of two numbers is 59 and the difference is 21. What are the numbers?
Larger number:
Smaller number: 0
2.

Answers

Answer: The larger number is 40.

The smaller number is 19

Step-by-step explanation:

x + (x-21) = 59 This is the number and the number difference add to 59.

x + x = 59 + 21 Add 21 to both sides. Combine like terms.

2x = 80 divide both sides by 2

x= 40 This is the first number. Subtract 21 to get the second number

40 - 21 = 19

The difference between 40 and 19 is 21.

19 + 40 = 59

Answers

Answer:

25/3

Step-by-step explanation:

Set the equations equal to each other since the lines are parallel.

(x+20)=(4x-5)

-x +5 -x +5

25/3 = 3x/3

x = 25/3

Since these equations are consecutive interior angles, they will add up to 180.
The equation will be (x+20)°+(4x-5)°=180.

(x+20)+(4x-5)=180
5x+15=180
5x=165
165/5x
=33°

You can make sure your answer is correct by putting your x back into the equation.
(33+20)+(4•33-5)
53+132-5
53+127
180
