Answer:

C, 7 1/2

Step-by-step explanation:

12 is 2/3 of 18, therefore 5 is 2/3 of something, so you divide 5 by 2/3 which is 15/2 which is 7 1/2

Answer: C

7 and 1/2"

Step-by-step explanation:

First, let's figure out what 12 is being multiplied by to get 18. To do this, we divide 18 by 12. We get 1.5. Now, to find x we multiply 5 by 1.5.

5 times 1.5 = 7.5 (AKA 7 and 1/2)

Which system of equations can be graphed to find the solution(s) to 4x2 = x2 + 7?

Darina [25.2K]

Answer:

See explanation

Step-by-step explanation:

To solve the equation $4x^2 =x^2+7$ graphically, we need to consider left and right parts of this equation separately.

Left side gives us the function $y=4x^2.$ The graph of this function is shown with green curve in attached diagram.

Right side gives us the function $y=x^2+7.$ The graph of this function is shown with blue curve in attached diagram.

The x-coordinates of the points of their intersections are the solutions to the equation $4x^2 =x^2+7$

From the graph you can see that the solutions are

$x_1\approx -1.528\\ \\x_2\approx 1.528$

schepotkina [342]

The height of lighthouse is 52.2 yards

Solution:

Given that photographer stands 60 yards from the base of a lighthouse and observes that the angle between the ground and the top of the lighthouse is 41 degree

The diagram is attached below

Consider a right angled triangle ABC

AB is the height of the lighthouse

BC is the distance between the base of a lighthouse and Photographer

As per given, BC = 60 yards

Angle between the ground and the top of the lighthouse is 41 degree

Angle ACB = 41 degree

To find: height of lighthouse i.e AB = ?

We know that,

$tan(\angle ACB) = \frac{Perpendicular}{Base}$

Here Base is BC and perpendicular is AB

$\tan 41^{\circ}=\frac{A B}{B C}$

Substituting the values,

$\begin{aligned}&\tan 41^{\circ}=\frac{A B}{60}\\\\&0.8692=\frac{A B}{60}\\\\&A B=0.8692 \times 60=52.157 \approx 52.2\end{aligned}$

Thus the height of lighthouse is 52.2 yards
