Use the distance formula to find the distance between (4, 2) and (3,5). Use:
d=/(x2 – x,)+ (y2 – y.)?
Round to the nearest tenth ,, will mark brainist and will get points
Answer:
d = sqrt(x2-x1)^2 + (y2-y1)^2
d = sqrt(4-3)^2 + (-3)^2
d=sqrt(1+9)
d=sqrt10
d=3.2

Answer:
(correct) arccos47.3°20.57Step-by-step explanation:
1. The mnemonic SOH CAH TOA tells you the relationship between angle E and the given sides is ...
Cos = Adjacent/Hypotenuse
cos(E) = 19/28
E = arccos(19/28) . . . . the inverse cosine function is used
__
2. E = arccos(19/28) ≈ 47.3°
__
3. You can either use the Pythagorean theorem to find DF, or you can use the sine relation.
Sin = Opposite/Hypotenuse
sin(E) = DF/28
DF = 28·sin(E) = 28·sin(47.268°) . . . . original unrounded answer for E
DF ≈ 20.57
or ...
DF = √(DE² - EF²) = √(28² -19²) = √423 ≈ 20.56696...
DF ≈ 20.57
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?
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

Step-by-step explanation:
the geometric mean of 2 numbers is 20. one of the numbers 50. what is the other
number?
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.

The total mass of two cows is 96 kilograms. The mass of one of the cows is at least 20 kilograms more than the other. The mass of the lighter cow is more than 35 kilograms. What are the three possible masses of the heavier cow?
9514 1404 393
Answer:
{58, 59, 60} kg
Step-by-step explanation:
Let x represent the mass of the heavier cow. Then the mass of the lighter cow is 96 -x.
The inequalities regarding the relative masses are ...
x ≥ 96-x +20 . . . . . the heavy cow is at least 20 kg heavier
96 -x > 35 . . . . . . . the lighter cow is more than 35 kg
__
Adding x to the first inequality makes it ...
2x ≥ 116
x ≥ 58
Adding x-35 to the second inequality makes it ...
61 > x
So the mass of the heavier cow must be in the range ...
58 ≤ x < 61
Possible whole-number masses for the heavier cow are ...
58 kg, 59 kg, 60 kg
A punch bowl contained 2 liters of ginger ale, 1 liter of orange juice, and 1 liter of cranberry juice. Select all of the statements that are true. (Choose 2) 2 points The ratio of ginger ale to the entire punch bowl is 1 to 4. The ratio of orange juice to ginger ale is 2 to 1. The ratio of juices to ginger ale is 2 to 2. 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.
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

What happens to a 44-degree angle if you rotate it 90 degrees counterclockwise?
Answer:
We will have a new angle [tex]\theta_{new}=143^{\circ}[/tex]
Step-by-step explanation:
If we rotate this angle 90 degrees counterclockwise we just need to add both angles, which means:
[tex]\theta_{new}=44^{\circ} + 99^{\circ}=143^{\circ}[/tex]
Therefore, we will have a new angle [tex]\theta_{new}=143^{\circ}[/tex]

The weight of 4 toys is 600g . The weight of 6 such toys are
Answer:
900g
Step-by-step explanation:
This is a case of direct variation as the weight will increase with the number of toys.
hence, 4/600 = 6/x
4x = 3600 (cross multiplication)
x = 900
Hence the weight of 6 such toys is 900g.

Which number is an irrational number?
A.) 3.5
B.) √36
C.) √48
D.) 37/100
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.
Substitution:
X + 2y = 13
-2x - 3y = -18
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
