Answer:

<em>276 guests were at the wedding. </em>

Step-by-step explanation:

$\frac{1}{3}$ + $\frac{5}{12}$ = $\frac{4+5}{12}$ = $\frac{9}{12}$

1 - $\frac{9}{12}$ = $\frac{3}{12}$ = $\frac{1}{4}$

$\frac{1}{4}$ of the guests are 69 guests ⇒ 69 × 4 = <em>276 guests were at the wedding.</em>

SIZIF [17.4K]

Answer:

The distance you are from the base of plateau = $99.97\ m\approx 100\ m$

Step-by-step explanation:

Given:

Height of plateau = 70 m

Angle of elevation to the top of plateau = 35°

To find the distance you are from the base of plateau.

We will construct a triangle ABC to model the given situation. The triangle would be a right triangle for which we know an angle and its opposite side. We need to find the adjacent side of the triangle.

We will apply trigonometric ratio to find the adjacent side.

$\tan\theta=\frac{Opposite\ Side}{Adjacent\ Side}$

where $\theta$ represents the angle of reference.

Plugging in the values from the triangle.

$\tan 35\° =\frac{BC}{AC}$

$\tan 35\° =\frac{70}{AC}$

Multiplying both sides by AC.

$AC\times \tan 35\° =AC\times \frac{70}{AC}$

$AC\times \tan 35\° =70$

Dividing both sides by $\tan 35\°$

$\frac{AC\times \tan 35\°}{\tan 35\°} =\frac{70}{\tan 35\°}$

∴ $AC=99.97\ m\approx 100\ m$

The distance you are from the base of plateau = $99.97\ m\approx 100\ m$

Devon wants to write an equation for a line that passes through 2 of the data points he has collected. The points are (8, 5) and

ser-zykov [4K]

For this case we have the following equation:
$7x - 10y = 3
$
From here, we must substitute ordered pairs of the form:
(x, y)
If the ordered pair satisfies the equation, then it belongs to the line.
We have then:

For (8, 5):
We substitute the following values:
$x = 8

y = 5

7 (8) - 10 (5) = 3

56 - 50 = 3

6 = 3$
We observe that the equation is not satisfied and therefore, this point does not belong to the line.
Since one of the points does not belong to the line, then the equation is not a good model.

Answer:
It is not a good model. One of the points does not belong to the line.

Custom drapes are being fitted for a large circular window. It is difficult to get these measurements, but the window has an 8 f

Arlecino [84]

Answer: 10 ft.

Step-by-step explanation:

Given: Custom drapes are being fitted for a large circular window.

The window has an 8 ft horizontal shelf with a 2 ft brace that sits in the frame.

Since the brace is extended upward, it would go through the center of the shelf and the circle.

Then the diameter of the circle= the measurement og f horizontal shelf + measurement of brace=8+2=10 ft

Hence, the diameter of the window =10 ft.
