why is the square root of (-5)^2 25 but the square root of -5^2 is -25?
Step-by-step explanation:
So, we call 5 the “square root” of 25 and write √25=5 because 52=25 . ... Since (−5)2 also equals 25 it is also a “square root” of 25 , but we write −√25=−5 because it is not the principal square root. Not all whole numbers have a whole number square root. For instance √2=1.414213562…A rate is a ratio? ( sometimes, always or never true?)

Graham's car gets 25 miles per gallon in the city and 30 miles per gallon on the highway. Graham drives in the city and on the highway for 200 miles. He uses 7 gallons of gasoline. How many miles did he drive in the city?
А 25
B 50
С 75
D 100
Answer:
B
Step-by-step explanation:
Let c represent the amount of gallons used in the city and h represent the amount of gallons used on the highway.
Graham drove a total of 200 miles. Since his car gets 25 miles per gallons in the city and 30 miles per gallon on the highway:
[tex]\displaystyle 25c + 30 h = 200[/tex]
And he used a total of seven gallons. In other words:
[tex]c + h = 7[/tex]
This yields a system of equations:
[tex]\displaystyle \left\{ \begin{array}{l} 25c + 30h = 200 \\ c + h = 7\end{array}[/tex]
Since we want to determine the number of miles Graham drove in the city, we will solve for c using substitution. From the second equation, solve for h:
[tex]\displaystyle h = 7 - c[/tex]
Substitute:
[tex]\displaystyle 25 c + 30 ( 7 - c) = 200[/tex]
Solve for c:
[tex]\displaystyle \begin{aligned} 25c + (210 - 30c) &= 200 \\ -5c &= -10 \\ c &= 2\end{aligned}[/tex]
Therefore, Graham used a total of two gallons in the city.
Since his car gets 25 miles per gallon in the city, Graham drove a total of:
[tex]\displaystyle \frac{25 \text{ mi}}{\text{gal}} \cdot 2\text{ gal} = 50\text{ miles}[/tex]
Or 50 miles in the city.
In conclusion, our answer is B.
Step-by-step explanation:
Let
Gallon in city = x
Gallon in highway = y
25x + 30y = 200 (i)
x + y = 7 (ii)
Multiplying ii by 30
30(x + y) = 30(7)
30x + 30y = 210 (iii)
On subtracting
30x + 30y - 25x - 30y = 210 - 200
5x = 10
x = 10/5
x = 2

Sophia used the Order of Operations to simplify 4(5 - 2) to 4x3.
Jose used the Distributive Property to simplify 4(5 - 2) to 20 - 8.
Are they both correct? Explain.
Answer:
YesStep-by-step explanation:
Order of operations, use the operation within the parenthesis:
1) 5 - 2 = 32) 4*3 = 12Distributive property, a(b + c) = ab + ac:
1) 4*5 - 4*2 = 20 - 82) 20 - 8 = 12Both ways are correct and lead to same result
Which answer gives statements that should be used to prove angles 2 and 7 are supplementary angles?
Answer:
Angles 2 and 6 are congruent as corresponding angles
Angles 6 and 7 form a linear pair.
Angles 2 and 6 are congruent as corresponding angles; angles 6 and 7 form a linear pair thus 2 and 7 will be supplementary angles so option (B) will be correct.
What is an angle?An angle is a geometry in plane geometry that is created by 2 rays or lines that have an identical terminus.
The identical endpoint of the two rays—known as the vertex—is referenced as an angle's sides.
In the given figure lines m and n is parallel.
So,
Angle 2 = Angle 6 (Congruent)
Now,
Angle 6 and 7 are on a straight line so they will be linear pairs.
∠2 + ∠3 = 180
∠6 + ∠7 = 180
So,
(∠2 + ∠3) + (∠6 + ∠7) = 360
(∠2 + ∠7) + (∠3 + ∠6) = 180 + 180
Each corresponding pair will be the same because of congruent.
So,
(∠2 + ∠7) = 180
Hence "Angles 2 and 6 are congruent as corresponding angles; angles 6 and 7 form a linear pair thus 2 and 7 will be supplementary angles".

Step-by-step explanation:
The attached shows the long division tableau. The "Hints" column shows how the quotient terms are developed, and how the expression is found that is subtracted from the dividend.
The overall form of this work matches that of numerical long division. The difference is that there are no carries from one power of n to another the way there is in numerical long division from one power of 10 to another. I find polynomial long division to be simpler.

3.There is a 30% chance of rain tomorrow.
What are the odds in favor of it raining?
10:3
7:3
3:10
3:7
Answer:
For Question 1 it's the first option
For Question 2 it is 7 percent
for the third question it is 3:10
1. Test results indicate that a patient has cancer when, in fact, he does not is False statement.
2. The probability of drawing a Queen, placing it back in the deck, and drawing any face card is 2%.
3. The odds in favor of it raining are 3:7.
1. The example of a false positive is:
Test results indicate that a patient has cancer when, in fact, he does not.
2. To find the probability of drawing a Queen, placing it back in the deck, and drawing any face card, we multiply the probabilities together.
There are 4 Queens in a deck of 52 cards.
So the probability of drawing a Queen is 4/52 = 1/13.
There are 12 face cards (4 Kings, 4 Queens, and 4 Jacks) in a deck of 52 cards.
So, the probability of drawing a face card is 12/52 or 3/13.
Now, the probability of both events happening, multiply the probabilities:
= (1/13) * (3/13)
= 3/169.
= 0.01775
Now, Converting 3/169 to a percentage and rounding to the nearest whole number, 2%.
Therefore, the probability of drawing a Queen, placing it back in the deck, and drawing any face card is 2%.
3. Given that there is a 30% chance of rain.
So, the probability of rain is 30/100 or 3/10.
The probability of no rain is the complement of the probability of rain, which = 1 - 3/10
= 7/10.
Therefore, the odds in favor of it raining are 3:7.

A farmer builds a fence for his chickens in the shape
of a pentagon, as shown. Each of the 5 sides has equal
length, but the fence along the highway costs twice as
much as any one of the other 4 sides. If the total cost
of fencing was $1800, how much did the highway
fence cost?
Answer:
The highway fence cost $600.
Step-by-step explanation:
Since the highway fence is twice as cost as the one of the other 4 sides, this means that the highway fence = 2 normal fence.
Therefore, we use
$1800 / highway fence(2 normal fence) + 4 normal fence
$1800 / (2 + 4) = $300
This means that every normal fence cost $300.
Which then we get the highway fence is $600 because it costs double of the normal fence.

1. In the given figure O is the centre and PQ is the diameter of the circle. if the chord PR is produced to S and QR is joined the what will be the value of the angle QRS?
Answer:
90°
Step-by-step explanation:
since PQ is the diameter of the circle, m L PRQ = ½ × 180° = 90°.
so, as a supplementary to L PRQ, the value of angle QRS = 180 - m L PRQ = 180-90 =90°
