53. A=6.

54.we use the Pythagorean theorem =>

8^2=(8:2)^2+x^2

64=16+x^2
x^2=64-16=48

=> A=sqrt(48)= 4*sqrt(3).

3x + 2y ≥ 120

you are asking me to confirm whether the below statement is true

10 * 3 + 45 *2 ≥ 120 ?

30 + 90 = 120

120 ≥ 120

its not greater but its equal which means it is a possible solution

Answer:

1/x^8

Step-by-step explanation:

x^3*x^2 = x^5

x*x*x*x*x*x*x = x^7

x^5 / x^7 = 1/x^2

(1 / x^2)^4 = 1^4 / x^2*4 = 1/x^8

Answer:

[tex]\frac{i\times d}{100}[/tex]

Step-by-step explanation:

To calculate the discount, we multiply the initial amount (i) to the discount (d) and then divide that answer by 100. After we find that answer we then subtract it from the initial price.

For example:

A computer costs $695 and it has a 7% discount. Calculate the total costs of the computer after the 7% discount.

[tex]\frac{695\times7}{100} =695\times7=4865\div100=48.65[/tex]
[tex]695-48.65=646.35[/tex]
[tex]c=646.35[/tex]

The computer (after a 7% discount) costs "$646.35 dollars."

Hope this helps.

Answer:

163

Step-by-step explanation:

What's great about these problems is that when there is a line that is divided by another line, causing 2 angles, the 2 angles must equal 180 degrees.  That means the 163-degree angle + either the x or the z angle would equal 180 degrees.  The second best part about this is that if it is separated how yours is, with 2 lines, opposite angles are equal.  That means that angle x and angle z are equal, as well as the 163 angle is equal to the y angle.  Hope this helps with more than just this problem!

x-Intercept: 600,0

y-intercept:0,450

The x intercept is 600, 0. The y intercept is 0, 450.

Step-by-step explanation:

I got it correct on edge.

0.0455 quarters of paints is not enough to paint the wall. she needs 15 quarters.

She needs 15 quarters of paint  for one wall .

She has 2 1 / 4 gallons left over from painting the other walls and she also has another 5 quarts that her neighbour gave her.

Therefore,

4 quarts = 1 gallon

5 quarts = 5 / 4 gallons

Then,

total gallon = 9 / 4 + 5 / 4 = 14 / 4  = 7 / 2 gallons

Therefore,

1 gallons = 0.01301053418982 quarters

7 / 2 gallons = ?

cross multiply

number of quarters = 3.5 × 0.01301053418982

number of quarters = 0.0455 quarters

Therefore, 0.0455 quarters of paints is not enough to paint the wall. she needs 15 quarters.

Answer:

-5

Step-by-step explanation:

negative times negative is positive so squared can be negative or positive

Answer:

x = -5, x = 5

Step-by-step explanation:

Tangents to a circle drawn to a point outside the circle are equal in length.  Therefore, AB = AC.

Given:

                                              AB = AC

                                      ⇒ x² + 8 = 33

Subtract 8 from both sides:   x² = 25

Square root both sides:          x = ±5

Therefore,                                x = -5, x = 5

Answer:

-2k

Step-by-step explanation:

Answer: You combine like terms

2k^3-2k^4

Answer:

0.750 kg

Step-by-step explanation:

Hi there ,

As you know 1 kg = 1000g

So when we convert g to kg then we divide the given value of grams by 1000.

So in this case we have 750 grams, changing it we have :

[tex]\frac{750}{1000}[/tex]

Since there are 3 zeroes in 1000 we move the decimal point by 3 places to the left leaving the answer as : 0.750 kg or [tex]\frac{750}{1000}[/tex] kg

Answer:

  2.735%

Step-by-step explanation:

The amount due on principal P after t years at rate r is ...

  A = P(1 +rt)

Filling in the given values, we can solve for r:

  20,953.80 = 18000(1 +6r)

  20953.80/18000 -1 = 6r = 0.1641

  r = 0.1641/6 = 0.02735 = 2.735%

Joel's interest rate was 2.735%.
