Find X. Round To The Correct Number Of Decimal Places.

Answers

Answer 1

Step-by-step explanation:

Using Trigonometry,

Let the height be AD, angle containing 90° be B and the angle containing 65° be C, respectively.

cos 30° = AD/40

AD= 40√3/2 = 20√3.

<DAC = 25°.

cos 25° = AD/AC

0.90 = 20√3/AC

AC = 38.49. is the value of x.

please try to understand the marking accordingly.

hope this helps you.

If the smaller of two numbers is one-half of the larger number and the sum of the 2 numbers is 75. What are the numbers?

Answers

Answer:

25 and 50

Step-by-step explanation:

Answer:

Smaller Number = 25

Bigger Number = 50

Step-by-step explanation:

let the smaller number be x

Let the bigger number be y

x + y = 75

x = 1/2y

Now we can substitute 1/2y for x

1/2y + y = 75

1 1/2 y = 75

y = 50

The bigger number is 50

The smaller number is 1/2 of 50, which equals 25

The equation y=6.5x represents a proportional relationship. What is the constant of proportionality?

Answers

Answer:

The constant of proportionality is 6.5.

Step-by-step explanation:

The constant of proportionality is the same thing as the slope and the equation of a line is y = mx + b, where m is the slope. Therefore, 6.5 is the slope because it is multipying by x.

amelia needs to buy some cat food at the nearest store 2 bags of cat food is 6.50. How much would it be if amelia bought 3 bags?

Answers

Answer:

$9.75

Step-by-step explanation:

We have all we need to solve for Bag #3.

2 bags equal $6.50.

We want 3 bags, not 4. So we need to divide the original cost by 1/2.

$6.50 divided by 1/2 is $3.25

Now we add an additional $3.25 to the original $6.50

First we can multiply both sides of the equation by 2 to get rid of the fraction.

(for the left side, the top doesn't change!)

12w - 20 = 12 - 4w

Then we can solve by adding 20 and 4w to both sides.

16w = 32

Last, divde both sides by 16.

w = 2

So our answer is the third option, w = 2

Answer:

Answer is w = -4

Step-by-step explanation:

[tex] \frac{12w - 20}{2} = 6 - 2w \\ 12w \div 2 = 6 \\ so \: we \: get \: 6 - 2w \\ now \: 6 - 2w = - 4[/tex]

Step-by-step explanation:

i got it right on edge .

The correct expressions that require the use of the distributive property to simplify are √5(√7-√2) and (√5+√2)(-√7)

What is Number system?

A number system is defined as a system of writing to express numbers.

Given the integers A, B, and C.

According to the distributive property;

A(B + C) = AB + AC

From the expression, you can see that A is distributed over B and C

So for distributive property, there must be a factor and the sum of terms in parenthesis.

Based on the given options the correct expressions that require the use of the distributive property to simplify are √5(√7-√2) and

(√5+√2)(-√7)

Hence,  the correct expressions that require the use of the distributive property to simplify are √5(√7-√2) and (√5+√2)(-√7)

I'm confused- how do I form the equation with 2 pts?

Write the equation of the line given the y-intercept and x-intercept.


y-intercept is (0, –6), x-intercept is (–2, 0)

Answers

Answer:

the equation of the line is   y = -3x - 6

Step-by-step explanation:

Note that since (0, -6) is the y-intercept, we can write the slope-intercept equation of the line as y = mx - 6.  The other given point is (-2, 0) (which happens to be the x-intercept also).  Starting with y = mx - 6, replace y with 0 and x with -2:  

0 = m(-2) - 6.  We now solve this for the slope, m:  0 = -2m - 6 becomes

2m = -6, or m = -3.

With m = -3 and b = -6, the equation of the line is   y = -3x - 6

A bad contains 35 colored maebles. There are 6 blue marbles. 7 red marbles. 12 yellow marbles and 10 clear marbles. What is the ratio of blue marbles to clear marbles

Answers

As the other person said 6:10 (6/10 | 6 to 10) however you wanna say it. Easy way to answer, the other variables don’t matter if you are into finding the ration of blue marbles to clear marbles. The variables for each are 6 and 10. They are asking blue first so obviously 6 would be listed for not 10:6. Thats really all, none of the other number matter because it’s only a ratio between two.
