Answer:

x = 1.5

y = -0.75

Step-by-step explanation:

4x - 2y = 6

<u>First</u> do 6 divided by 4 = 1.5 so x = 1.5

<u>Then</u> do 1.5 divided by -2 = -0.75 so y = -0.75

Craig is standing on his apartment balcony and locates his car in the street-level parking lot below. The angle of depression of

murzikaleks [220]

Answer:

B. 147 feet

Step-by-step explanation:

We can easily imagine a right triangle for this problem. The height of the triangle is what we're looking for (x), at the bottom of x, we have the right angle formed by the building and the ground. The other side of that right angle is the distance to the car (300 ft). On top of the x side, we have the angle of 63 degrees looking down, since Craig is looking down by 27 degrees (90 - 27 = 63).

We can easily apply the Law of Sines that says:

$\frac{a}{sin(A)} = \frac{c}{sin(C)}$

Then we can isolate c and fill in the values:

$c = \frac{a * sin(C)}{sin(A)} =\frac{300 * sin(27)}{sin(63)} = 153$

So, we know Craig's eyes are 153 feet above ground... since Craig is 6 feet tall, the balcony sits at 147 feet high (153 - 6 = 147).

Four times a number increased by one is between a negative seven and thirteen. Find all numbers.

aleksley [76]

Answer:

Step-by-step explanation:

Let the number be x.

four times the number:

If the exprression is increased by 1, it will become:

4x+1

If the value is between -7 and 13, the value of x will be within the range [-6, 12]

Equating the resulting expression to each end point.

At end point of -6

4x+1 = -6

4x = -6-1

4x = -7

x = -7/4

At the end point of 12:

4x+1 = 12

4x = 12-1

4x = 11

x = 11/4

Hence all the numbers will be within the range [-7/4, 11/4] or -7/4≤x≤11/4

How many centimeters are there in 1 foot? There are 12 inches in 1 foot. the ratio of centimeters to inches by the number of inc

Darya [45]

Answer:

There are 0.0328 centimeters in 1 foot.

Step-by-step explanation:

Given : There are 12 inches in 1 foot.

To find : How many centimeters are there in 1 foot?

Solution :

1 foot = 12 inches

and 1 inch = 2.54 centimeter

So, 12 inches = $12\times 2.54$ centimeter

12 inches = 30.48 centimeter

i.e. 1 foot = 30.48 centimeter

Then, 1 centimeter = $\frac{1}{30.48}$ foot

1 centimeter = 0.0328 foot

Therefore, there are 0.0328 centimeters in 1 foot.
