Answer:

317.52

Step-by-step explanation:

Label the point where the altitude meets the base P and the end points of the base A and B where m∠A = 27 and m∠B = 41

tan 27 = 102/AP    and tan 41 = 102/PB

APtan 27 = 102            PBtan 41 = 102

AP = 102/tan 27                 PB =  102/tan 41

AP = 200.186                     PB = 117.338

x = AP + PB = 200.186 + 117.338 = 317.52

Answer:

36.24

Step-by-step explanation:

- 3 * 2 = - 6

73 / 76 = 0.96

0.96 * (-6) = -5.76

Answer:

x ≥-4

Step-by-step explanation:

-7x+13 ≥41

-7x ≥28 (subtraction property of equality on both sides-subtract 13)

x ≥-4 (division property of equality on both sides-divide by -7)

5. is completely write though

Hope that helps

Answer:

Question 5: x = 12, Question 6: y = 2[tex]\sqrt{3}[/tex]

Step-by-step explanation:

Use the Pythagorean Theorem to calculate missing sides.

Question 5 explanation: [tex]x^{2} + 9^2 = 15^2[/tex]n:  ⇒ [tex]x^{2} + 81 = 225[/tex] ⇒ [tex]x^{2} = 144[/tex] ⇒ [tex]x=12[/tex]

Question 5 explanation: [tex]y^{2}+6^2 =(4\sqrt{3})^2[/tex] ⇒ [tex]y^{2} + 36 = 48[/tex] ⇒ [tex]y^2 = 12[/tex] ⇒ [tex]y=2\sqrt{3}[/tex]

Answer:

x = -8

Step-by-step explanation:

11x– 1 = -89

Add 1 to each side

11x– 1+1 = -89+1

11x = -88

Divide each side by 11

11x/11 = -88/11

x = -8

Answer:

Step-by-step explanation:

For mixture problems, I like to use a single variable to represent the quantity of the greatest contributor (greatest cost or greatest concentration). Let that variable be x.

1. In this problem, the amount of the greatest contributor is already fixed, so we'll use x for the amount of walnuts. The cost of the mix is ...

  0.80x + 1.25(8) = 1.00(x +8)

  2 = 0.2x . . . . . . . . . . . . . . . . . subtract 0.8x+8, simplify

  10 = x . . . . . . . . . divide by 0.2

10 pounds of walnuts must be used.

__

2. The amount of acid in the mix is ...

  12%(8 -x) +32%(x) = 20%(8)

  20%(x) = 8%(8) . . . . . . . . . . . . subtract 12%(8)

  x = 8(8)/20 = 3.2 . . . . . . . . . . divide by 20%

  8-x = 4.8

3.2 liters of 32% acid must be mixed with 4.8 liters of 12% acid

_____

Comment on mixture problems

The general solution for mixture problems that have a greater contributor (G), a lesser contributor (L), and a mix value (M) is ...

  g/l = (M -L)/(G -M) . . . . . . ratio of quantities of G and L

In the first problem, this becomes ...

  8/l = (1.00 -.80)/(1.25 -1.00) = .2/.25 = 4/5  ⇒  l = 8(5/4) = 10

In the second problem, this becomes ...

  g/l = (20-12)/(32-20) = 8/12 = 2/3  ⇒  g = (2/5)(8) = 3.2; l = (3/5)(8) = 4.8

In this case, we recognize that the ratio of 2 parts to 3 parts means that the greater contributor is 2 of 5 total parts.

Answer:

we have a rule

(x-h)²+(y-v)²=r²

while h is the x intercept

v is y intercept

r is the radius

so the answer will be

x²+y²=400

or

x²+y²=20²

Answer:

38.57 feets

Step-by-step explanation:

Given that:

Height of monument, h = 300ft

Shadow of monument, s = 210 ft

Shadow of tree, s = 27ft

Height of tree, = x

Using the relation :

Height / shadow = height / shadow

Monument = tree

300 / 210 = h / 27

Cross multiply

300 * 27 = 210 * h

8100 = 210h

h = 8100 / 210

h = 38.57 feets
