Answer:

.25

Step-by-step explanation:

.5 times .5 or half of half is .25

(½)²  is 1²/2² so the answer is 1/4.

When we multiply a number by it self once the number is squared.We add 1 to the exponent.We must also remember squares of numbers from 1 - 20 for us to solve questions related to squares and square roots.

For example - (5)² is 25. { 5² is 5 multiplied by it self once (5×5)}.

Also square root of 25 is 5.We can find square root of any given perfect square number by prime factorisation.

According to the given question we have find what is the square of half.

(1/2)²

= (1×1)/(2×2)

= 1²/2²

= 1/4.

So, square of half is one fourth.

Answer:

x=-14.5

Step-by-step explanation:

5x-5=3x -9 –1 –2 1 –3

group like terms

5x-3x=-9 –1 –2 1 –3+5

2x=-29

divide by two

x=-14.5

Step-by-step explanation:

4.37

28.17-23.8=4.37

$145.60 / 7 hours = $20.8 / hour

$83.20 / $20.8 = 4 hours

Jose would have to work 4 hours to make $83.20

X → first

X + 2 → second

X + 4 → third

X + 4 → fourth

x + x + 2 + x + 4 + x + 6 = 100

4x + 12 = 100

4x = 88  

x = 22

x + 2 = 24

x + 4 = 26

x + 6 = 28

So your integers are 22, 24, 26, and 28.

A consecutive number is a number directly following another number.

For instance, 1 and 2 are consecutive numbers

So x + (x + 1) = 71 is the only correct choice

The cost of milk powder is $3 per bottle

An equivalent expression for the total cost of Will's beverages during this month is 60 - m dollars

Step-by-step explanation:

The given information are;

The items Will buys every weekday after tennis practice = A carton of milk or a bottle of powder drink

The number of milk purchased during the month = m

Will's total cost for beverages in dollars last month = 2·m + 3·(20 - m)

1) Therefore, given that the total amount is factored in dollars, we have;

2·m and 3·(20 - m) are dollar amounts, while, m is a quantity;

Therefore;

Where;

2·m = The total cost of the cartons of milk, then the factor 2 represents $2.00 which is the cost per carton of milk

Similarly, 3·(20 - m) can be said to represent the total cost of the powder drink then the factor 3 represents $3.00 which is the cost per powder drink and the factor (20 - m), represents the number of powder drink Will buys for the month

From which we found the cost of milk powder = $3.00 per bottle

2) The expression, 2·m + 3·(20 - m) simplifies to 2·m + 60 - 3·m, which gives;

2·m + 60 - 3·m = 60 - m which is an equivalent expression for the total cost of Will's beverages for the month.

Answer:

Step-by-step explanation:

We need to create an equation to represent how many air fresheners the teacher can buy.

Teacher has $10 and a $3 discount coupon which would give her an extra $3 to spend. Each air freshener is $3.50.

x = number of air fresheners

($10 + $3) / $3.50 = x        can be written as $13/$3.50 = x

We add $10 and $3 because that gives us the total amount she has to spend.

We divide by $3.50 because that is the cost of each air freshener. The result is the number of air fresheners she can buy.

In this case.

$13/$3.50 = x

3.71 = x   BUT we can't buy part of an air freshener, so she can purchase 3 air fresheners.

Hey there!!!!

We generally sum up all the angles to get 360° as per given in our question.

Here, in your question, we have values as,

x, 2x, 100°, 110°.

(We have 360° as the sum quadrilateral).

So, x° + 2x° + 100°+110° = 360°

3x°+210°= 360°

3x° = 360° - 210°

or, 3x° = 150°

[tex]x = \frac{15 0 }{3} [/tex]

Therefore the measure of 2x is (2×50)°=100°.

Hopeit helps...

Answer:

X=50; 2x=2×50=100

Step-by-step explanation:

sum of angles in a quadrilateral is 360°

Therefore; x+2x+100+110=360;

3x+210=360;

3x=360-210;

3x=150;

divide both sides by the co-efficient of x;

3x/3=150/3;

x=50;

therefore 2x=2×50;

2x=100.

Answer:

D: All real numbers or (-∞, ∞)

R: (-∞, 2] or y ≤ 2

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

Domain:

The graphed function has arrows on both ends, meaning that it will extend to -∞ and ∞. Therefore the Domain is:

D: All real numbers or (-∞, ∞)

Range:

The graph extends downward infinitely, so the graph will extend to y = -∞ as x ⇒ -∞ and x⇒ ∞.

The graphed function has a maximum, or greatest y-value at y = 2, therefore:

R: (-∞, 2] or y ≤ 2

Answer:

Zero

Step-by-step explanation:

First you do (3-2) which is one then you multiply that by five which gives you 5. Then you will subtract 5 from each side and that leaves you with 15a=0. Divide both sides and you’ve got zero

Answer:

Step-by-step explanation:

1. add 8 to both sides to get d=25

2. subtract 12 from both sides to get v=-17

3. add 2 to get b=-9

4. subtract m to get -16-m=71 then add 15 to get -m=87 then divide both sides by - to get m by itself so m=-87

5. subtract a then subtract 29 to get -a=-105 then divide it by - to get a=105

6. add 14 to both sides to get y=12

hope this helps :)

Answer:

For ax^2+bx+c=0,

x^2+x(-2-k)+4=0,

So, b=-2-k,

a=1, c=4, so

(-2-k)^2-(4*1*4)>0,

4+4k+k^2-16>0,

k*2+4k-12>0,

(k+6)*(k-2)>0,

the points of interest are

k=-6, k=2, so

look at k<-6, -6<k<2, and

k>2.

Just plug in values for each

interval and you will see

that k<-6 and k>2.

Answer:

x = 26 and y = 17

Step-by-step explanation:

x is the larger number and y is the smaller number

the difference is 9 ⇒ x - y = 9

Five times the smaller is 7 more than 3 times the larger ⇒ 5y - 3x = 7

x - y = 9 ⇒ x = 9 + y (1)

substitute x = 9 + y in  5y - 3x = 7

5y - 3(9 + y) = 7

5y - 27 - 3y = 7

2y = 7 + 27

2y = 34

y = 34/2

y = 17

x = 9 + 17

x = 26
