Someone please help me answer Number 14, PLEASE!

THE ANSWER: the answer is 58°

Answer:

x = 20

Step-by-step explanation:

We can use ratios to solve

10         16

-----  = -------

12.5       x

Using cross products

10x = 16*12.5

10x =200

Divide each side by 10

10x/10 = 200/10

x = 20

Answer:

Domain: (−∞,∞),{x|x∈R}

Range: (−∞,∞),{y|y∈R}

Find the domain by finding where the function is defined. The range is the set of values that correspond with the domain.

Domain: (−∞,∞),{x|x∈R}

Range: (−∞,∞),{y|y∈R}

Answer:You need to see if the half of the ratio table is equal

Answer:

477 boys would be there.

Explanation:

boys to girls is 2:3

3 units --->  716

1 units ---> (716/3)

then boys ---> (716/3) * 2

                ---> 477 boys

Or basically:

(716/3) * 2

477 boys

Step-by-step explanation:

the angle of elevation is the angle on the ground at the end of the shadow abs aiming towards the sun.

we know one angle : the 90° between the tree and its shadow (on the ground).

so, we can calculate with Pythagoras the length of the line of sight bergen the end of the shadow and the top of the tree, which is the Hypotenuse of this right-angled triangle.

Hypotenuse² = 32² + 35² = 1024 + 1225 = 2249

Hypotenuse = sqrt(2249) = 47.42362281... m

the height of the tree is the sine of the angle of elevation multiplied by the length of the Hypotenuse (as the radius of the virtual circle).

32 = sin(angle) × sqrt(2249)

sin(angle) = 32/sqrt(2249) = 0.6747692...

angle of elevation = 42.43622979...° ≈ 42°

Hi!

The Desmos graph is below.

According to the graph, we can see that one of the points is (1, -5).

Additional information:

In inequalities, each equation will be shaded a certain direction/side, and anything in that shaded region is a solution to the equation. With 2 inequalities, the solutions to the equations will be in the double-shaded region.

Also, inequalities will either have a dotted (- - - - -) line or a solid (───) line. You will use a dotted line for inequality equations with > or < symbols, and solid lines for inequality equations with ≥ and ≤ symbols.

Step-by-step explanation:

screens are measured from corner to corner meaning that from the top left to bottom right the tv is 72 inches

since we know the tv is 36 in tall and 72 across we can use the Pythagorean theorem to find how wide it is by doing 72^2-36^2

so the tv is 62.35 in wide

so it will fit in the 70-inch wide gap

Step-by-step explanation:

Here we will, Provide index power 5 on both the sides, so that we can cancel out the 5th power root in the L.H.S

so we get as,

==> x+7 = (-2)^5

==> x+7 = -32

==> x = -32-7

==> x = -39

hence, x = -39

Answer:

slope = 1

y-intercept = (0 , -4)

x - intercept = (4 , 0)

Step-by-step explanation:

y = mx + b

m = slope

b = y-intercept

Note that there is no number besides the x. When this happens, the slope is to be assumed as 1.

The number (and sign) that replaces the b is the y-intercept. In this case, it is (0 , -4).

The x-intercept is the point in which you intercept the y-line at 0. Plug in 0 for y, and solve for x:

0 = 1(x) - 4

0 = x - 4

0 (+4) = x - 4 (+4)

x = 4

x-intercept = (4 , 0)

Answer: x = 6

Step-by-step explanation:

Because we are given that the two figures are already similar, we can set up a proportional relationship to determine the value of x. Since the larger rectangle has a width of 21 and the smaller rectangle has a width of 7, those values can be used as the numerators in the proportion. Since the larger rectangle's length is x plus the additional 3 units on the smaller rectangle, x+3 and 3 can be used as the denominators in the proportion.

Next, we set up the proportion as follows:

[tex]\frac{21}{x+3} =\frac{7}{3}[/tex]

Then, you cross multiply to get the equation:

[tex]63=7x+21[/tex]

After solving down algebraically, you get the value of x to be 6.

Answer:

The coordinates of point C' are (4, -2)

here's why:

When you reflect a point across the y-axis, the y-coordinate remains the same, but the x-coordinate is taken to be the additive inverse. The reflection of point (x, y) across the y-axis is (-x, y). So if we use this information with the original coordinates, (-4, -2), the new coordinates will be (4, -2).

The population of the United States in 2008 is 298528793.

Gross domestic product (GDP) is the total monetary or market value of all the finished goods and services produced within a country's over a specific time period

GDP per person = GDP / Population

From the question, GDP = $14.204 trillion, GDP per person was $47,580. Hence:

47580 = 14.204 * 10¹² / Population

Population = 298528793

Answer:

The family's average rate of travel for the day was 59.0 MPH.

Step-by-step explanation:

From 10:15AM to 4:45PM, they travelled a distance of 383.5 miles and a total of 6 hours and 30 minutes.

There are 60 minutes in an hour. 30 minutes translates into 1/2 an hour or .5

So, 6.5 hours and a total distance of 383.5 miles.

Velocity (MPH) = Distance (in miles) / Time (in hours)

MPH means Miles Per Hour

Variables:

Velocity (MPH) = x

Distance (in miles) = 383.5

Time (in hours) = 6.5

Plug in the variables into the formula

x = 383.5 / 6.5

Divide

x = 59.0 MPH

Answer:

59 miles/hr

Step-by-step explanation:

To solve this, lets make the time in 24 hours format:

10:15 am = 10 hours and 15 minutes

4:45 pm = 16 hours and 45 minutes

so time taken = ( 16 hours and 45 minutes ) - ( 10 hours and 15 minutes )

                       = 6 hours 30 minutes

                       = [6 + (30/60)] hours

                       = 6.5 hours taken for the journey to complete

Average rate of travel = Total distance / time taken

                                     = 383.5 / 6.5

                                     = 59 miles/hr
