Answer:

18

Step-by-step explanation:

Since this is a multiple choice question, I will employ the guess and check method - meaning I will check each answer one by one.

Variable x = dimes = $0.10

Variable y = quarters = $0.25

Set up a system of equations:

x + y = 38

x(0.10) + y(0.25) = 6.80

Plug in each choice into the second equation. You can find the number of quarters that correspond to each number of dimes by using the first equation.

20 dimes:

20 + y = 38

y = 18

20(0.10) + 18(0.25) = 6.80

2 + 4.5 = 6.80

6.5 does not equal 6.80

Because dimes (x) are worth less than quarters (y), this result tells us the answer will be less than 20 dimes as with 20 or more we have less than $6.80. Another example just to show this is true:

38 dimes:

38 + y = 38

y = 0

38(0.10) + 0(0.25) = 6.80

3.8 + 0 = 6.80

3.8 does not equal 6.80.

Since x is worth less than y, we need more of y rather than x. Adding more x will only mean we will get a lower price. Adding more y will mean we get a higher price which is what we need. So only solve for x that is less than 20.

6

6 + y = 38

y = 22

6(0.10) + 32(0.25) = 6.80

0.60 + 8 = 8.60

8.60 does not equal 6.80.

This result is higher than what we wanted (6.80) which means we need more x. Now we only have to solve for x numbers that are greater than 6 and less than 20.

18

18 + y = 38

y = 20

18(0.10) + 20(0.25) = 6.80

1.8 + 5 = 6.8

6.8 does equal 6.8.

Correct!

Answer:

RMN+117°=180

RMN=63°

Angle RMN is on the straight line with <117 in which the sum of angle on a straight line add up to 180 so we subtract 117 from 180 to get RMN

Answer:

Perimeter = 24 units

Area = 36 square units

Step-by-step explanation:

An archaeologist divides an area using a coordinate plane in which the coordinates are measured in meters. The vertices of a secret chamber are (-4,-1), (2,-1) , (2,5) , and (-4,5) . Find the perimeter and the area of the secret chamber.

We have to find the length of the sides of the rectangle using the formula below

= √(x2 - x1)² + (y2 - y1)² when given vertices (x1, y1) and (x2, y2)

For sides A

(-4,-1), (2,-1)

= √(2 - (-4))² + (-1 -(-1))²

= √(2 + 4)² + (0)²

= √6²

= √36

= 6 units

Side B

(2, -1), (2,5)

= √(2 - 2)² + (5 - (-1))²

= √0² + (5 + 1)²

= √0 + 6²

= √36

= 6 units

For side C

(2,5) , and (-4,5)

= √(2 - (-4))² + (5 - 5)²

= √6² + 0²

= √36

= 6 units

For side d

(-4,-1), (-4,5)

= √(-4 - (-4))² + (5 - (-1))²

= √(-4 +4)² + (5 + 1)²

= √0 + 6²

= √36

= 6 units

From the above calculation, all the sides of the secret chamber are equal to one another

Side a = Side b = Side c = Side d

This means the chamber is has the shape of a square.

The perimeter of the secret chamber =

P = 4a

a = Length of one side = 6 units

P = 4 × 6 units

P = 24 units

The area of the secret chamber

A = a²

a = Length of one side = 6 units

A = ( 6 units)²

P = 36 square units

Answer:

Area = lw

11 x 6 = 66

Answer is 66 cm squared

Answer:

no

Step-by-step explanation:

Using the converse of Pythagoras' identity.

If the square of the longest side is equal to the sum of the squares of the other 2 sides then the triangle is right.

longest side = 30 , then 30² = 900

20² + 23² = 400 + 529 = 929 ≠ 900

Then the triangle is not right.

Answer:

B. -7 is less than or equal to x, which is less than 12

Step-by-step explanation:

-7x -50 </= -1

add 50 to both sides

-7x <= 49

divide both sides by -7. When you divide and inequality by a negative number, the direction of the inequality changes.

x >/= -7

---------------------------------

-6x + 70 > -2

subtract 70 from both sides

-6x > -72

divide both sides by -6, flipping the inequality sign

x < 12

------------------------------

Since the problem says *and*, we can say x is equal than or greater to -7 and less than 12

-7 </= x < 12

Answer:

Option B

Step-by-step explanation:

It's given that p + q has a value of [tex]\frac{12}{5}[/tex]

So the equation representing the relation will be,

p + q = [tex]\frac{12}{5}[/tex] --------(1)

Value of p is [tex]\frac{4}{5}[/tex]

p = [tex]\frac{4}{5}[/tex]

By substituting the value of p in the equation (1),

[tex]\frac{4}{5}+q=\frac{12}{5}[/tex]

q = [tex]\frac{12}{5}-\frac{4}{5}[/tex]

q = [tex]\frac{8}{5}[/tex]

Therefore, Option B will be the correct option.

Answer:

$4895

Step-by-step explanation:

P(winning) = 1 / 1000000 = 0.000001

P(not winning) = 1 - 1/1000000 = 0.999999

Winning amount = 4,900,000,000 - 5 = 4899999995

Amount lost = - 5

__ X: - 5 _________ 4899999995

P(X) : 0.999999 ___ 0.000001

Expected value E(x) = Σx * p(x)

E(x) = - 5(0.999999) + 4899999995(0.000001)

E(x) = - 4.999995 + 4899.999995

E(x) = 4895

Hence, expected value is 4895

Answer: 5/8

Step-by-step explanation:

Probability of getting a red jellybean = 1/8

Probability of getting an orange jellybean = 1/4

Probability of getting a yellow jellybean = 1 - (⅛ + ¼)

= 1 - (1/8 + 2/8)

= 1 - 3/8

= 5/8

Therefore, the probability of getting a yellow jellybean is 5/8
