6. $1 \frac{1}{2} = \frac{6}{4}$ since $\frac{1}{4} = 4$ feet. Then 6*4=24 So the answer is C

7. 1200 m/8 cm = C. 1 cm = 150 m

8. A. Since 1 in = 3 feet then 6 inches = 18 feet (6*3=18) and 4 inches = 12 feet (4*3=12) so the dimensions of her room are 16'x12'.

B. A=lxw so 16*12= 216 $m^{2}$

Hope that helps

the parabola y=x^2 is shifted up by 2 units and to the right by 3 units. what is the equation of the new porabola

Juli2301 [7.4K]

Up 2 units = y shifted up by 2:
y = x^2 + 2
to the right 3 units = x shifted right (+) by 3:
y + 3 = x^2 +2
new equation:

How tall is a building that casts a 78-ft shadow when the angle of elevation of the sun is 30 degrees?

Marta_Voda [28]

Answer: $45.03\ ft$

Step-by-step explanation:

Given

The length of the shadow is 78 ft

the angle of elevation is $\theta =30^{\circ}$

Suppose the height of the building is $h$

From the figure, we can write

$\tan 30^{\circ}=\dfrac{h}{78}\\\\h=78\tan 30^{\circ}\\\\h=45.03\ ft$

The height of the building is 45.03 ft
