In ΔCDE, the measure of ∠E=90°, the measure of ∠D=50°, and DE = 8. 1 feet. Find the length of CD to the nearest tenth of a foot

Answer:

  12.6 ft

Step-by-step explanation:

Trig functions relate the sides and angles in a right triangle. Here, we're given an angle and an adjacent side, and we're asked to find the hypotenuse. The relevant trig relation is ...

  Cos = Adjacent/Hypotenuse

  cos(50°) = DE/CD = (8.1 ft)/CD

Solving for CD, we find ...

  CD = (8.1 ft)/cos(50°) ≈ 12.601 ft

The length of CD is about 12.6 feet.

natita [175]

Answer:

20

Step-by-step explanation:

Maya has 120 caramel apples to sell.

Each caramel apple is covered with one topping.

1/5 of the caramel apples are covered with peanuts.

1/3 of the caramel apples are covered with chocolate chips.

3/10 of the caramel apples are covered with coconut.

The rest are covered with sprinkles.

find:

How many caramel apples are covered with sprinkles?

120 = (1/5 * 120) + (1/3 * 120) + (3/10 * 120) + sprinkles

120 = 24 + 40 + 36 + sprinkles

sprinkles = 120 - 24 - 40 - 36 = 20

therefore,

there are 20 caramel apples covered with sprinkles.

If the equation below represents the total cost of 3 boxes of cereal and 2 loaves of bread is $15," then x represents
Liula [17]

Answer:

C. The cost of a box of cereal

Step-by-step explanation:

In the question, we are given the number of 3 boxes of cereal, 2 loaves of bread, and that the total cost is $15. We can see these numbers in the equation, and putting it into context, we see that the 15 is on the right side of the equation, which indicates cash. Therefore, the 3 and 2 are accounted for, but their prices are unknown. X is a placeholder for the unidentified cost of a box of cereal, and we know that it's the boxes of cereal and not the loaves of bread because there are 3 and not 2.

What is the domain and range of y=-1/4(x)
LenKa [72]

Domain: (-\infty, \infty)

Range: (-\infty, \infty)

Explanation:

The function is y=-\frac{1}{4} x

The domain of a function is the set of all input values for which the function is well defined. Generally, domain consists of all x-values of the function. Hence, the function y=-\frac{1}{4} x is defined in the interval (-\infty, \infty).

The range of a function is the set of output values obtained by substituting the value of x in the function. Hence, the function y=-\frac{1}{4} x is defined in the interval (-\infty, \infty).

I need helpppppp asap
user100 [1]

Answer:

graph A

Step-by-step explanation:

When looking at a graph, there are two different axes. The vertical values--marked by the center up/down line--are "y-values"; and this is called the "y-axis"

The horizontal values--marked by the left/right line--are "x-values"; and this is called the "x-axis"

For the x-axis, values to the left side of the origin (the place where the y-axis and x-axis intercept) are smaller than 0--they are all negative values.

Values to the right side of the origin are positive--greater than 0.

For the y-axis, positive numbers are on the top half [once again, the midpoint / 0 is where the two lines are both = to 0; the origin] and negative numbers are on the bottom half.

Ordered pairs (points) are written as (x,y)

(x-value, y-value)

We are looking for a graph that decreases (along the y-axis), hits a point below the origin, and goes flat/stays constant.

When a graph is decreasing (note: we read graphs from left to right), the line of the graph is slanted downwards (it looks like a line going down).

So, if we look at the graphs, we can see Graph A descending, crossing the y-axis {crossing the middle line /vertical line / y-axis} at a value of -7, and then staying constant (it is no longer increasing or decreasing because the y-values stay the same)

hope this helps!!
