Answer:
69
Step-by-step explanation:
to get from 1 to 23 on the denominator, they multiplied it by 23
what you do to the denominator, you must do to the top
3*23= 69
Answer: 480 ft
Step-by-step explanation:
We can use Similarity of Triangles.
| lighthouse
60 ft | ruler
|___________ 3 in |__
x 2 ft
3 inches = 0.25 ft
60/0.25 = x/2
0.25x = 120
x = 120/0.25
x = 480 ft
A) tomatoes : chicken broth = 9:15 or 3:5
Tomatoes : spinach = 9:9 = 1:1
Spinach : chicken broth = 9:15 = 3:5
b) tomatoes : chicken broth = 4.5:7.5 = still 3:5
Tomatoes to spinach is still 1:1
Spinach : chicken broth 4.5:7.5 still = 3:5
Dividing all quantities by 2 doesn’t change the ratio.
Answer:
72.2 = 2x + 40.6
Step-by-step explanation:
Formula for perimeter of a rectangle = 2( width + lenght)
P = 2 ( w + l)
P= 2w + 2l (i)
We have been given that width = x
and lenght = 20.3 inches and P = 72.2 inches
We substitute the values of P, w and l into equation (i)
72.2 = 2x + (2*20.3)
72.2 = 2x + 40.6
Step-by-step explanation:
By the exterior angle theorem,
10x+36+7x=23x
17x+36=23x
36=6x
x=6
So measure of angle MAE is 23(6)=138 degrees
