Answer:
The correct answer is 47 degrees.
Step-by-step explanation:
Use cosine.
cos(x)= adj/hyp
cos(x)=19/28
x=arccos(19/28)
Use a calculator
x is approximately 47 degrees.
Answer:
y = 3x+4
Step-by-step explanation:
The slope intercept form of a line is
y = mx+b where m is the slope and b is the y intercept
y = 3x+4
Step-by-step explanation:
x= number of lawns Jonas needs to mow
40x+650=6750
Now Solve!!!
First subtract 650 from both sides
40x=6100
Now divide by 40
x=152.5 lawns
Jonas can't mow 1/2 a lawn, so he would have to mow 153.
Answer:
C. 2:5
Step-by-step explanation:
You can divide both side of the ratio 20:50 by 5 which leaves you with 4:10. You can simplify it again by dividing it by 2 and get 2:5
Rectangle Z is not a scale drawing of Rectangle Y.
This is because there is no equal sides where it makes up the constant proportionality.
6/4 (= 3/2) in the left and right sides of the rectangle (Y/Z)
4/3 in the top and bottom sides of the rectangle (Y/Z)
As you can see 3/2 is not equal to 4/3 of scaling, so therefore it is not a scaling.
