Answer:

x = 4

Step-by-step explanation:

Given

$\frac{1}{3}$ = $\frac{x}{12}$ ( cross- multiply )

3x = 12 ( divide both sides by 3 )

x = 4

Distance between (-4, 6) and (3, 7)

sweet-ann [11.9K]

Answer: $5\sqrt{2}$

Step-by-step explanation:

$Distance\ formula=\sqrt{(x_2-x_1)^2+(y_2-y_1)^2} }$

plugging in the values we know:

$x_2 = 3,\ x_1=-4,\ y_2=7,\ y_1=6$

Therefore,

$Distance=\sqrt{(3-(-4))^2+(7-6)^2}$

$\rightarrow\ \sqrt{(3+4)^2+(1)^2}$

$\rightarrow\ \sqrt{7^2+1}$

$\rightarrow\ \sqrt{50}$

$\rightarrow\ \sqrt{5\times5\times2}$

$\rightarrow\ \large\boxed{5\sqrt{2}}$

weqwewe [10]

Complete Question:

The deck that Amos is building is in the shape of a parallelogram, DGRY. The measure of D is five-halves the measure of Y. Find the measure of each angle of the deck.

Answer:

$\angle G = \angle Y = 51.43 ^{\circ}$

$\angle D = \angle R = 128.57 ^{\circ}$

Step-by-step explanation:

Given

Shape: Parallelogram DGRY

Dimension: $\angle D = \frac{5}{2}\angle Y$

Required

Find the measure of each angle

D and R are opposite sides & G and Y are also opposite sides.

So, we have:

$\angle D = \angle R = \frac{5}{2}\angle Y$

and

$\angle G = \angle Y$

The sum of angles is given as:

$\angle D + \angle G + \angle R + \angle Y=360^{\circ}$

Substitute values for $\angle D, \angle G \ \& \angle R$

$\frac{5}{2}\angle Y + \frac{5}{2}\angle Y + \angle Y + \angle Y = 360^{\circ}$

Take LCM

$\frac{5\angle Y + 5\angle Y + 2\angle Y+ 2\angle Y}{2}= 360^{\circ}$

$\frac{14\angle Y}{2}= 360^{\circ}$

Multiply both sides by $\frac{2}{14}$

$\frac{2}{14} * \frac{14\angle Y}{2}= 360^{\circ} * \frac{2}{14}$

$\angle Y= 360^{\circ} * \frac{2}{14}$

$\angle Y= \frac{ 360^{\circ} *2}{14}$

$\angle Y= \frac{720^{\circ}}{14}$

$\angle Y= 51.43 ^{\circ}$

So:

$\angle G = \angle Y = 51.43 ^{\circ}$

$\angle D = \frac{5}{2}\angle Y$

$\angle D = \frac{5}{2} * 51.43^{\circ}$

$\angle D = \frac{5* 51.43^{\circ}}{2}$

$\angle D = \frac{257.15^{\circ}}{2}$

$\angle D = 128.57 ^{\circ}$

Hence:

$\angle D = \angle R = 128.57 ^{\circ}$

An arts academy requires there to be 3 teachers for every 75 students and 6 tutors for every 72 students. How many tutors does t

suter [353]

5 teachers and 10 tutors because we can make a proportion:

3/75=x/120, and when you cross multiply and solve for x you will get 4.8, but there can't be 4.8 teachers so we can say 5 teachers (round). Do the same for tutors: 6/72=x/120, x would equal 10.

Hope this helps!
