Need help with these 3

Tamiku [17]

Answer:

1.) x = 110

$\frac{3}{22} =\frac{15}{x}$

So for 3 to become 15 it would have to be multiplied by 5 because 3 x 5 = 15. And if I multiply the numerator by anything I always have to do the same to the denominator. So I multiply 22 x 5 = x. x = 110

$\frac{3 * 5}{22*5} =\frac{15}{110}$

2.) x = 72

$\frac{x}{16} =\frac{9}{2}$

For 16 to become 2 it has to be divided by 8 because 16 ÷ 8 = 2. And I have to do the same to the numerator of course, so i have to find x ÷ 8 = 9. I know the answer by memory, but for some it's easier to rewrite this as 9 × 8 = x. x=72

$\frac{72}{16} =\frac{9}{2}$

3.) c = 24

$\frac{3}{5} =\frac{c}{40}$

For 5 to become 40 it must be multiplied by 8 because 5 × 8 = 40. I have to multiply 8 by the numerator as well and 3 × 8 = 24. c = 24

$\frac{3*8}{5*8} =\frac{24}{40}$

Need help with a math question

Mekhanik [1.2K]

Answer:

$z =3\sqrt{13}$

Step-by-step explanation:

In the figure you can identify up to 3 straight triangles.

To solve the problem, write the Pythagorean theorem for each triangle.

Triangle 1

$13^2 = z^2 + x^2$

Triangle 2

$z^2 = y^2 + 9^2$

Triangle 3

$x^2 = y^2 + 4^2$

Now substitute equation 2 and equation 3 in equation 1 and solve for y.

$13^2 = y^2 + 9^2 + y^2 + 4^2$

$13^2 = 2y^2 + 9^2 + 4^2$

$169 = 2y^2 + 81 + 16$

$2y^2 =72$

$y^2 =36$

$y =6$

substitute the value of y in the second equation and solve for z

$z^2 = 6^2 + 9^2$

$z^2 = 36 + 81$

$z^2 = 117$

$z = \sqrt{117}$

$z =3\sqrt{13}$

Write the equation of a line that has a slope of 1/3 and a y intercept at (0,4)

Rus_ich [418]

Answer:

y = 1/3x + 4

Step-by-step explanation:

The slope intercept form is y=mx+b so what we need to do is fill in the blanks. M is the slope and we know the 1/3 is the slope. (0,4) is basically meaning that the x-value is 0 and the y-value is 4, and when that's the case it means 4 is the y-intercept. Now we can put the information together y = 1/3x +4 is the equation.

Hope this helps and have a great day!
