Answer:
C) 40°
Step-by-step explanation:
The given angles are opposites, so will be equal to each other:
4x +4 = 6x -14
18 = 2x . . . . . . . . . . add 14-4x
9 = x
Then the angle measure is ...
∠ACD = (4(9) +4)°
∠ACD = 40°

Zander uses an on-line store that sells songs for $1 each and movies for $6. He used all of his $20 allowance to buy 10 items. How many songs and how many movies did he buy?
Answers
Answer:
2 movies and 8 songs
Step-by-step explanation:
use the formula 1x + 6x = $20 and x + x = 10. so x has to equal to 10, so 1 times 8 is 8 and 6 times 2 is 12. The x’s (8 and 2) equal 10 which is what you were looking for. i don’t know if that made sense but i hope it did
Which number is an irrational number?
A.) 3.5
B.) √36
C.) √48
D.) 37/100
Answers
Answer:
the answer is c
Step-by-step explanation:
square root of 36 = 6 = 6 / 1D. 37 / 100 is already a fraction. Hence, the only number that cannot be written as a fraction is the square root of 48. The answer is C: the square root of 48 is an irrational number.

the geometric mean of 2 numbers is 20. one of the numbers 50. what is the other
number?
Answers
Answer:
8
Step-by-step explanation:
Let x = the unknown no.
Then
[tex]\frac{50}{20} = \frac{20}{x}[/tex]
50x = 400
x = 8
If the geometric mean of two numbers is 20, one number is 50 then the other number is 8
What is geometric mean?"The geometric mean is the average rate of return of a set of values calculated using the products of the terms."
Formula to calculate geometric mean is
[tex]GM = \sqrt{x_{1}.x_{2} }[/tex]
Here,
GM = 20
[tex]x_{1}=50\\ x_{2} =?[/tex]
Substitute the values in the formula
[tex]20=\sqrt{50.x_{2} }[/tex]
Squaring on both sides
[tex]400=50(x_{2})\\ x_{2} =\frac{400}{50} \\x_{2}=8[/tex]
Hence, the other number is 8.

Witch is better to buy $6.15 for 24 fl oz of dishwashing liquid or $9.60 for 42 fl oz of dishwashing liquid?
Answers
Answer:
$9.60 for 42 fl oz
Step-by-step explanation:
$6.15 x 2=$12.30
$12.30 for 44 fl oz
$12.30-$9.60=$2.70
you would be paying $2.70 for 4 fl oz when 4 fl oz is 93 cent
Answer: 42 fluid ounce unit of dish soap.
Step-by-step explanation: Why? Well, 24 times 2 gives you 48 fluid ounces for $12.30. But for just 4 less fluid ounces of soap, you pay $9.60. This is just over a dollar for every two ounces of soap. So $12.30- $9.60= $2.70. this shows you`d need to buy two 24 ounce bottles. *So if you ONLY BUY ONE 24 OUNCE SOAP* you are getting a bad deal. In order to make a better deal buy two 24 ounce bottles to get four more ounces and pay $2.70 more. Hence you only ask about buying one, so 42 ounces is your go to choice.

The ratio of the entire punch bowl to the juices is 2 to 4. The ratio of orange juice to the cranberry juice is 1 to 1.
Answers
Answer:
The ratio of juices to ginger ale is 2 to 2
The ratio of orange juice to the cranberry juice is 1 to 1
Step-by-step explanation:
Ginger ale = 2 liters
Orange juice = 1 liter
Cranberry juice = 1 liter
Total ratio = 2 + 1 + 1 = 4
The ratio of ginger ale to the entire punch bowl is 1 to 4.
Ginger ale : entire punch bowl
= 2 : 4
= 1 : 2
Not true
The ratio of orange juice to ginger ale is 2 to 1.
Orange juice : ginger ale = 1 : 2
Not true
The ratio of juices to ginger ale is 2 to 2.
juices : ginger ale = orange juice + cranberry juice : ginger ale
= 1 + 1 : 2
= 2 : 2
True
The ratio of the entire punch bowl to the juices is 2 to 4.
Entire punch bowl : juices 4 : 2
Not true
The ratio of orange juice to the cranberry juice is 1 to 1.
Orange juice : cranberry juice = 1 : 1
True

x = 14 ; y = 7√2
Step-by-step explanation:
This is a right triangle. One of the angles is 45. So is the other base angle.
So one of the legs is 7√2. The other leg is also 7√2 because they are opposite equal angles.
The hypotenuse is
a^2 + b^2 = c^2
a = b
2a^2 = c^2
2 (7√2)² = c^2
2 49 * 2 = c^2
4 * 49 = c^2
c^2 = 196
c = 14
Substitution:
X + 2y = 13
-2x - 3y = -18
Answers
Answer:
x = -3
y = 8
Step-by-step explanation:
x + 2y = 13 ------------(I)
x = 13 - 2y -----------(II)
-2x - 3y = -18 ----------(III)
Substitute x = 13 - 2y in equation (III)
-2*(13 - 2y) - 3y = -18
-2*13 - 2y *(-2) -3y = -18
-26 + 4y - 3y = -18 {Combine like terms}
-26 + y = -18 {Add 26 to both sides}
y = -18 + 26
y = 8
Substitute y = 8 in equation (II)
x = 13 - 2*8
= 13 - 16
x = -3
x = -3
y = 8
