Step-by-step explanation:

9514 1404 393

Explanation:

If the amount of change due to rounding is the same for both numbers, the original difference and the difference of rounded values will be the same. This will always be the case if the hundredths digits are the same to start with.

Example:

  A = 0.56 ⇒ C = 0.6

  B = 0.66 ⇒ D = 0.7

__

B - A = 0.66 -0.56 = 0.10

D - C = 0.7 -0.6 = 0.10 . . . . . same as B - A, ∴ Dominic is incorrect.

Answer: You do not because the tv costs $464.

Step-by-step explanation:

First find out how much 20% of 580 is:

= 20% * 580

= $116

The television was therefore marked down by $116. The current selling price is:

= 580 - 116

= $464

Since you came with $450, you will not be able to buy the television as you would be short of the $464 required.

Answer:

54 Degrees

Step-by-step explanation:

We know that the interior angles of a triangle add up to 180 degrees.

we also know that angle KLM = 48 degrees

and angle JKM = 78 degrees

since these triangles are on parallel lines we know that their angles must be equal (just inverted)

and thus:

180 - (48+78) = 54

Answer:

25%

Step-by-step explanation:

90 / 120 = .75 or 75%

Verify:  120*.25 = 30

Answer:

∠F=78.58484226°

Step-by-step explanation:

a²=b²+c² - 2bc cosA

DE²=EF²+DF² - 2(EF)(DF)cos∠F

18²=16²+12²-2(16)(12)cos∠F

324=256+144-384cos∠F

324-400=-384cos∠F

76=384cos∠F

0.197916=cos∠F

∠F=cos⁻¹(0.197916)

∠F=78.58484226°

Answer:

I can't place them it is a picture

Step-by-step explanation:

Answer:

ans: (D) 141°

Step-by-step explanation:

since, straight angle has 180°

180 = 39 + N

N = 180 - 39

N = 141°

Answer:

t = 2+x / x-3

Step-by-step explanation:

x = 3t + 2 / t - 1

x * (t-1) = 3t + 2

xt - x = 3t + 2

xt - 3t = 2 + x

t(x - 3) = 2 + x

t = 2+x / x-3

Answer:

12.5 cups used

7.5 cups left

Step-by-step explanation:

Number of batches = 5

Cups of flour per batch = 2 1/2 cups

Initial amount of flour = 20 cup bag

After 5 batches ; number of cup used :

5 * 2 1/2 = 12.5 cups of flour

Change in amount of flour in bag :

(20 cups - 12.5 cups) = 7.5 cups

Answer:

Note that the tangents to the circles at A and B intersect at a point Z on XY by radical center. Then, since∠ZAB=∠ZQA and ∠ZBA=∠ZQB. ∠AZB+∠AQB=∠AZB+∠ZAB+∠ZBA=180°. ∴ZAQB is cyclic.But if O is the center of w, clearly ZAOB is cyclic with diameter ZO, so ∠ZQO is 90° ⇒Q is the mid-point of XY.Then, by Power of a Point, PY· PX = PA · PB = 15 and it is given that PY+PX = 11. Thus,PX=(11±[tex]\sqrt{61}[/tex])/2. So, PQ=[tex]\frac{\sqrt{61} }{2}[/tex], PQ²=[tex]\frac{61}{4}[/tex]. Thus, the answer is 61+4=65.

Step-by-step explanation:

-5x-10+5x-25

Answer:

-5x-10+5x-25

x-10=-25

x=-15

Step-by-step explanation:

you distribute both 5s into the problem. one side will be negative 5x minus 2 becomes 10 because negative times a positive is a negative. you're multiply negative 5 times 2 bring down the plus sign. the second part is positive 5x minus 5 which becomes 5x minus 25. you multiply positive 5 times 5 to get that answer for the second part. you combine like terms. positive 5x and negative 5x cancels out to become x-10=-25. add 10 on both sides and x=-15

Answer:

y=15

Step-by-step explanation:

u can find y int by making the value of x=0

so

0^2-5*0+15=y

y=15

Answer:

x < 5

Step-by-step explanation:

Mark the number as x

Then 3x + 3 < 18

// divide both sides by 3

x + 1 < 6

x < 6 - 1

x < 5

Answer:

Friday's drink will taste more like soda and Saturday's drink will taste more like orange juice.

Step-by-step explanation:

Not sure if this is the exact answer you want, but we can use fractions to determine how much one drink tastes compared to the other.

For Sam's Friday drink, we see that he makes 7 liters of orange soda by mixing 3 liters of orange juice with 4 liters of soda. As such, we know that [tex]\frac{3-liters-of-orange-juice}{7-total-liters}[/tex] and [tex]\frac{4-liters-of-soda}{7-total-liters}[/tex].

For Sam's Saturday drink, we can also approach it the same way: the drink has [tex]\frac{4-liters-of-orange-juice}{9-total-liters}[/tex]  and [tex]\frac{5-liters-of-soda}{9-total-liters}[/tex]

Now, we can just compare the fractions with each other:

[tex]\frac{4-liters-of-orange-juice}{9-total-liters}[/tex]   >  [tex]\frac{3-liters-of-orange-juice}{7-total-liters}[/tex] and

[tex]\frac{4-liters-of-soda}{7-total-liters}[/tex] > [tex]\frac{5-liters-of-soda}{9-total-liters}[/tex].

So we know that the Saturday drink will probably taste more like orange juice than the Friday one. Conversely, we know that the Friday drink will probably taste more like soda than the Saturday one.

Answer:

[tex]-a^{18}[/tex]

Step-by-step explanation:

So we have [tex](-a^{3} ) ^{4} *-a^{6}[/tex]

First what we must do is do the rule of out exponent by in exponent. A.K.A in parenthesis and out parenthesis.

So [tex](-a^3) ^4[/tex]

3 * 4 = 12

[tex]a^{12}[/tex]

Now do the additive property :

[tex]-a^{12} * a^6[/tex]

12 + 6 = 18

[tex]-a^{18}[/tex]

Answer:

In the Alan account is 77$

Step-by-step explanation:

The answer is 77$ because the sum of their savings is $89 and the difference is $12 you have to substract 89-12 and the result is 77$.

The money saved in Alan's savings account is $38.5.

Given that, Kira has more in her savings account than Alan has in his.

A system of linear equations consists of two or more equations made up of two or more variables such that all equations in the system are considered simultaneously. The solution to a system of linear equations in two variables is any ordered pair that satisfies each equation independently.

Let the money in Kira's savings account be x and the money in Alan's savings account be y.

The sum of their savings is $89.

So, x+y=89 --------(I)

The difference is $12

So, x-y=12 --------(II)

Add equation (I) and (II), we get

x+y+x-y=89+12

⇒ 2x=101

⇒ x=$50.5

Substitute x=50.5 in equation (I) and simplify, we get

50.5+y=89

⇒ y=89-50.5

⇒ y=$38.5

Therefore, the money saved in Alan's savings account is $38.5.
