Answer:

x = 4[tex]\sqrt{3}[/tex]

Step-by-step explanation:

Using the sine ratio in the right triangle and the exact value

sin60° = [tex]\frac{\sqrt{3} }{2}[/tex] , then

sin60° = [tex]\frac{opposite}{hypotenuse}[/tex] = [tex]\frac{x}{8}[/tex] = [tex]\frac{\sqrt{3} }{2}[/tex] ( cross- multiply )

2x = 8[tex]\sqrt{3}[/tex] ( divide both sides by 2 )

x = 4[tex]\sqrt{3}[/tex]

Answer:

[tex]\frac{1}{9}[/tex]

Step-by-step explanation:

The quantities must be in the same measure

3 feet = 3 × 12 = 36 inches ( 1 foot = 12 inches )

Then

fraction = [tex]\frac{4}{36}[/tex] = [tex]\frac{1}{9}[/tex]

Answer:

Second choice.

Step-by-step explanation:

Option 1: solve the inequality. Add 7 to both sides, and multiply by -3 (don't forget that this makes the inequality switch direction!) to get [tex]x > {27 \over {-3}[/tex] or x > -9

Option 2. Plug 0 in it. You get -7 < 20, which is obviously true. So 0 is in the set of solution and it means B and C are possible solutions. So let's check another easy value. let's say -10. replacing it you get [tex]-3 (-10) -7 < 20[/tex] or [tex]30 -7 <20[/tex]. But 23 is obviously greater than 20, which means -10 is not a part of the solution. Correct answer is B

Answer:  220 miles

Step-by-step explanation:

(150 miles)/(7.5 inches) = 20 miles/inch

(20 miles/inch)*(11 inches) = 220 miles

Answer:

64 ounce bottle of orange juice  has a greater percent of water

Step-by-step explanation:

Case 1) An 80 ounce bottle of apple juice contains 32 ounces of water

Total quantity of bottle = 80 ounces

Amount of water = 32 ounces

So, Percent of water = [tex]\frac{32}{80}[/tex] x 100

                                 = 40%

Case 2) An 64 ounce bottle of orange juice has 48 ounces of water

Total quantity of bottle = 64 ounces

Amount of water = 48 ounces

So, Percent of water = [tex]\frac{48}{64}[/tex] x 100

                                 = 75%

Hence 64 ounce bottle of orange juice  has a greater percent of water

Answer:

x= 7

B= 112

F= 68

Step-by-step explanation:

to find x we set up an equation, (16x)=(4x+84). They are alternate interior angles which are always equal.

calculate it and you'll find x=7.

B and the angle 4x+84 are equal because they are vertical angles, to find it we just put 7 instead of x into 4x+84.

4(7)+84=112

angle f is supplementary to 16x. 16x is also 112 because they are equal, so its just 180-112=68

Answer:

Step-by-step explanation:

Look at the last term, - 28.

It means, the product of roots is a positive number (28).

The polynomial is a degree three so it has 3 possible roots.

Positive product can be obtained if all 3 numbers are positive or 2 negative and 1 positive.

Therefore number of positive roots is one or three.

Further, double check using the graphical solution (see attached), it shows one root only. It means the other roots are complex.

Correct option is A

Answer:

Points ( 0, 13) , ( 30, 18) , ( 90 ,28)

Rate = y2-y1/x2-x1

Rate = 28-13 / 90-0 = 1/6 inches / Mins

Or

Rate = 18-13/30-0 = 1/6 inches / Mins

Answer:

x = 90

Step-by-step explanation:

[tex]\frac{2}{9}x+\frac{1}{5}x=38\\\\\frac{10}{45}x+\frac{9}{45}=38\\\\\frac{19}{45}x=38\\\\x=90[/tex]

Answer: It would take 24 years to double your investment.

Hope this helps!

Sam will have doubled his investment for 33 years.

percentage, a relative value indicating hundredth parts of any quantity.

Given that Sam invests a sum of money into an account that pays 3%

compound interest per annum

We need to find how many years Sam will have doubled his investment.

With C your initial capital, k the interest rate and t the number of years. Since k is given as a simple interest rate, you’re essentially trying to solve :

C(1+tk)=2C

With a little bit of algebra, you should find that:

t=1/k

k=3%=0.03

t=1/0.03=33.33=33 years.

Hence,  Sam will have doubled his investment for 33 years.

In other words, -4 goes in the first blank and 8 goes in the second blank

========================================================

Explanation:

Parallel lines have equal slopes, but different y intercepts.

The slope of y = -4x+1 is m = -4. So our answer will have this slope as well.

Use (x,y) = (2,0) along with that mentioned slope to get...

y = mx+b

0 = -4*2+b

0 = -8+b

0+8 = b

8 = b

b = 8 which is the y intercept

So we have m = -4 and b = 8 take us from y = mx+b to y = -4x+8

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

As a check, plugging x = 2 should lead to y = 0

y = -4x+8

y = -4*2+8

y = -8+8

y = 0

The answer is confirmed.

3 is a prime number - the GCF is 1, and the least common multiple of 3 and 8 is 24.

Answer:

Greatest Common Factor is 1

Least Common Multiple is 24

Step-by-step explanation:

Greatest common factor is the biggest whole number that can be multiplied into the numbers. In this case 1x8=8 and 1x3=3.

Least common multiple is the smallest number each number can multiply into. In this case 3x8=24 and 8x3=24

The sum of the measure of angle ∠AXY and angle ∠YXB is the measure of ∠AXB.

The relationship between ∠AXY and ∠YXB is that they are;

Reasons:

From the diagram in the question, we have;

∠BXC = 90° Given

∠BXC and ∠BXA are linear pair angles

Therefore;

∠BXC and ∠BXA are supplementary angles, which gives;

∠BXC + ∠BXA = 180° definition of supplementary angles

Therefore;

∠BXA = 180° - ∠BXC

∠BXA = 180° - 90° = 90°

∠BXA = 90°

∠AXY + ∠YXB = ∠BXA by angle addition property

Which gives;

Therefore ∠AXY and ∠YXB are;
