Murrr4er [49]

Yo sup??

we know that the sum of all the angles of a triangle is 180

therefore

11x+7x+90=180

18x=90

x=5

exterior angle formed on the ground=180-11x

=180-55

=125

Hope this helps

What is the y intercept of y=4^x

Misha Larkins [42]

Y intercept of a function can be obtained by evaluating the value of the function when x=0, i.e.

y-intercept of f(x) = f(0)

Here, f(x) = 4^(x)

so y-intercept = f(0) = 4^0 = 1

Lisa has 12 more stickers than John, and together they have 60 stickers. What is the ratio of the number of Lisa’s stickers to t

Harman [31]

Answer:

The ratio of the number of Lisa’s stickers to the number of John’s stickers is 3/2

Step-by-step explanation:

Step 1

Let

x ----> the number of stickers that Lisa has

y ----> the number of stickers that John has

we know that

$x+y=60$ ------> equation A

$x=y+12$ ----> equation B

Solve the system by substitution

Substitute equation B in equation A and solve for y

$(y+12)+y=60\\ 2y=60-12\\ 2y=48\\ y=24$

Find the value of x

$x=y+12$ -----> $x=24+12=36$

therefore

Lisa has 36 stickers and John has 24 stickers

Step 2

Find the ratio of the number of Lisa’s stickers to the number of John’s stickers

x/y

substitute

$\frac{36}{24}=\frac{3}{2}$
