Answer:

7) $3.50 8) 24% 9) 45% 10) 291

Step-by-step explanation:

7) Set up as so 25/100 = x/14

25 x 14 = 350

350/100 = 3.5

8)Set up as 19/25=x/100

19 x 100 = 1900

1900/25 = 76

100 - 76 = 24%

9)Set up as 36/80 = x/100

36 x 100 = 3600

3600/80 = 45

10) Set up as x/300 = 3/100

300 x 3 = 900

900/100 = 9

300-9 = 291

So the ration is 4:7

The total of houses is 32 new houses. What I did was I divided 32 by 4:

32/4 = 8

That means that the ratio (4:7) would be multiplied by 8 (only the :7 part):

7 * 8 = 56

There are 56 old houses (the ratio is now 32:56)

Answer:

[tex]\sqrt{143}[/tex]

Step-by-step explanation:

Use pythagorean theorem to find the missing side.

[tex]a^2+b^2=c^2[/tex]

[tex]1^2+b^2=12^2\\1+b^2=144\\b^2=143\\b=\sqrt{143}[/tex]

This can not be simplified any further.

The third side in simpliest radical form is [tex]\sqrt{143}[/tex].

Answer:

The answer is d

Step-by-step explanation:

Start with the y intercept and them go up two places over 1

Answer:

1. A point at (0, -3) and a point at (1, -1) and connect them

2. A point at (0, 4) and a point at (3, 6) and connect them

Step-by-step explanation:

The last number in the slope intercept form is the y-intercept, so that's one point down. Then all you gotta do is use the slope and do rise over run technique to find another point and then connect them!

Answer: Hehe hewo!!!

Step-by-step explanation: Wuv wou :P

Answer:

1 ) y = 2x - 1

slope = 2

y intercept is (0,-1)

2) y = -1/2x + 5

slope = -0.5

y intercept  = (0,5)

Step-by-step explanation:

Answer: D = 8

Step-by-step explanation:

From C to A, you can count the distance, and from C and A are 8 points so the answer is 8 :)

Answer:

D = 8

Step-by-step explanation:

C is at (-4, 3)

A is at (4, 3)

If you count the number of units in between the points then there are 8 units between both points, so your answer would be 8.

3-|4-n|>1

Subtract 3 from both sides:

-|4-n| > -2

Multiply both sides by -1:

|4-n| < 2

Apply the absolute rule:

-2<4-n <2

4-n > -2

n < 6

4-n < 2

N >2

Combine the intervals:

2<n<6

(2,6)

The solution to the inequality is: 2<n<6.

" In mathematics, inequality is a statement of an order relationship—greater than, greater than or equal to, less than, or less than or equal to—between two numbers or algebraic expressions."

Given inequality: 3-|4-n|>1

⇒ - |4 - n| > -2   [by subtracting 3 on either side of the inequality]

⇒ |4-n| < 2        [multiplying by'-1' on either side of the inequality]

⇒ -2<4-n <2     [using absolute rule]

Therefore, 4-n > -2

⇒ -n > -6

⇒ n < 6

Again, 4-n < 2

⇒ -n < -2

⇒ n > 2

By combine two intervals, we can say: 2<n<6

Hence, the value of n lies in between (2,6).

Answer:

Cooking magazine = 27

Baseball magazine = 32

Step-by-step explanation:

Total number of magazine = 59

Cooking magazine = x

Baseball magazine = x + 5

Total number of magazine = Cooking magazine + Baseball magazine

59 = x + (x + 5)

59 = x + x + 5

59 = 2x + 5

59 - 5 = 2x

54 = 2x

Divide both sides by 2

x = 54 / 2

= 27

x = 27

Cooking magazine = x

= 27 magazine

Baseball magazine = x + 5

= 27 + 5

= 32 magazine

Answer:

ok so a way to do this is that

Answer:

Answer A

Step-by-step explanation:

Angle A = 180 - 26 - 90 (90 right angle)

The cosine of an angle is equal to the ratio of the adjacent side to the hypotenuse.

cos ( A)= adj/hyp

Cos (26) = a / 13

a = 13* Cos (26)

a= 11.7
