Answer:

Step-by-step explanation:

Midpoint = (x₁+ x₂)/2 , (y₁ +y₂)/2

= [(-1)+(-3))/2] , (-2 + 9)/2

= (-4/2) , (-7/2)

= (-2 , -3.5)

Can someone give me the answer?

24 is the correct answer because the question is about triangle similarity so if you divide 15 by 3 then you get 5 which is the base of the smaller triangle.

The point P = (x, - 2/7) lies on the unit circle shown below. What is the value of x in simplest form?

miskamm [114]

Answer: $x = \frac{3\sqrt{5}}{7}\\\\$

Explanation:

The equation of the unit circle is $x^2+y^2 = 1\\\\$

Plug in y = -2/7 and solve for x

$x^2+y^2 = 1\\\\x^2+\left(-\frac{2}{7}\right) = 1\\\\x^2+\frac{4}{49} = 1\\\\x^2 = 1-\frac{4}{49}\\\\x^2 = \frac{49}{49}-\frac{4}{49}\\\\x^2 = \frac{45}{49}\\\\x = \sqrt{\frac{45}{49}} \ \ \text{ ... x is positive}\\\\x = \frac{\sqrt{45}}{\sqrt{49}}\\\\x = \frac{\sqrt{9*5}}{7}\\\\x = \frac{\sqrt{9}*\sqrt{5}}{7}\\\\x = \frac{3\sqrt{5}}{7}\\\\$

A new Youth Sports Center is being built in Hadleyville. The perimeter of the rectangular playing field is 536 yards. The lengt

Aleksandr [31]

Answer:

W = 58 yards, L = 210 yards

Step-by-step explanation:

P = 2 (L + W)

L = 4w - 22

P = 2 (4W - 22 + W)

536 = 8W - 44 + 2W

536 = 10W - 44

10 W = 536 + 44

10W = 580

W = 58 yards

Since L = 4W - 22

L = 4 (58) - 22

L = 232 - 22

L = 210 yards

If a 12-student class averaged 90 on a test, and a 20-student class averaged 80 on the test, then all 32 students averaged

Alexxx [7]

Let the marks of the students in class 1 be

$m_1, m_2, ....., m_1_2$

the average of these 12 marks is 90, so

$\frac{m_1+ m_2+ .....+ m_1_2}{12}=90$

which means

$m_1+ m_2+ .....+ m_1_2=90*12=1080$

similarly, let $n_1, n_2, ....., n_2_0$ be the marks of the students in the second class,

so $\frac{n_1+ n_2+ ..... n_2_0}{20}=80$

which means $n_1+ n_2+ ..... n_2_0=80*20=1600$

The 32 students averaged:

$\frac{(m_1+ m_2+ .....+ m_1_2)+(n_1+ n_2+ ..... n_2_0)}{12+20}= \frac{1080+1600}{32}= \frac{2680}{32}= 83.75$
