Mhanifa please help! Solve each proportion. Round your answer to the nearest hundreth
Marianna [84]

Answer:

  • 5) m/5 = 7/2 ⇒ m = 5*7/2 ⇒ m = 35/2
  • 6) 7/4 = r/5 ⇒ r = 5*7/4 ⇒ r = 35/4
  • 7) 7/6 = 5/x ⇒ x = 5*6/7 ⇒ x = 30/7
  • 8) 6/5 = 2/(5n) ⇒ 5n*6 = 5*2 ⇒ n = 10/30 ⇒ n = 1/3

Find the measure of angle y. Round your answer to the nearest hundredth. (please type the numerical answer only)
Eduardwww [97]

Given:

The figure of a right triangle. PO=12,m\angle O=y^\circ and perpendicular = 12.

To find:

The measure of angle y.

Solution:

In a right angle triangle,

\sin\theta=\dfrac{Perpendicular}{Hypotenuse}

In the given right angle triangle,

\sin y^\circ=\dfrac{7}{12}

y^\circ=\sin ^{-1}\dfrac{7}{12}

y^\circ=35.685335^\circ

y^\circ\approx 35.69^\circ

Therefore, the measure of angle y is y^\circ =35.69^\circ.

Using the numbers 1 through 9 only once in the boxes, what is the largest value of x you can get?
aliina [53]

Using the numbers 1 through 9 only once in the boxes, the largest value of x you can get is <u>7</u>.

<h3>What are mathematical operations?</h3>

Mathematical operations refer to the calculation of values using operands and mathematical operators.

Mathematical operations are formed like functions to take zero or more input values (operands) to a well-defined output value.

Some of the mathematical operators perform addition, subtraction, multiplication, division, exponentiation, and modulus operations.

<h3>Data and Calculations:</h3>

Mx + y = z

Let m = 1

x = 7

y = 2

1 x 7 + 2 = 9

7 + 2 = 9

9 = 9

Thus, using the numbers 1 through 9 only once in the boxes, the largest value of x you can get is <u>7</u>.
