Mathematics

leonid [27]3 years ago

Answer:

B, D, and E.

Step-by-step explanation:

20% is 20/100, or 0.2

so, if we put 20/100 instead of 20%, we get 20/100*45

the same goes for the rest of them. (remember, 1/5 is the same as 0.2)

Answer:

B. \: \frac{1}{5} \cdot 45

E.\: 0.2 \cdot 45

D. \: \frac{20}{100}\cdot 45

Step-by-step explanation:

% means /100

20\% = \frac{20}{100} \\\\20/100 =0.2\\= 0.2\cdot 45\\\\\frac{20}{100}=\frac{1}{5}  \\\\= \frac{1}{5} \cdot 45

What is the value of x?
Lunna [17]

Answer:

x = 23 degrees

Step-by-step explanation:

sin theta = opposite side/ hypotenuse

sin x= 9/23

Take the arcsin of each side

arcsin( sinx) = arcsin (9/23)

x = arcsin (9/23)

x=23.03568411

Rounding to the nearest degree

x = 23 degrees

Graph the following lines and write the equation in slope-intercept form. With y intercept of −3 and an x intercept of −4.5.
makvit [3.9K]

Answer:

y=-\frac{2}{3}x-3

Step-by-step explanation:

To write the equation of a line we need 2 points. We know:

  • If the y-intercept of the line is -3 then the point is (0,-3).
  • If the x-intercept of the line is -4.5 then the point is (-4.5,0).

Using these two point, we will find the slope and then substitute it into the point slope form y-y_1=m(x-x_1) with a point.

Slope: m=\frac{0--3}{-4.5-0}=\frac{0+3}{-4.5}=\frac{3}{-4.5}=-0.6667

This decimal is -2/3. We will now substitute -2/3 and (0,-3) into the point slope form.

y--3=-\frac{2}{3}(x-0)\\y+3=-\frac{2}{3}(x)\\y+3=-\frac{2}{3}x\\y=-\frac{2}{3}x-3
