Step-by-step explanation:
rc = planted rows of carrots
rt = planted rows of tomatoes
h = number of hours
rc = 4h + 1 (starting with 1 already finished row there will be 4 additional rows every hour)
rt = 3h + 8 (staying with 8 already finished rows there will be 3 additional rows every hour).
when will they have planned the same number of rows ?
when rc = rt, of course.
so,
4h + 1 = 3h + 8
h = 7
4×7 + 1 = 28 + 1 = 29 rows
after 7 hours Quincy and his mom will each have planted 29 rows of vegetables.
Using proportions, the value of x that makes the triangle similar is of x = 14.
<h3>What is a proportion?</h3>
A proportion is a fraction of a total amount, and the measures are related using a rule of three.
In this problem, we want the triangles to be similar, hence the lengths of it's sides follow the proportion given next:
Applying cross multiplication:
6x = 12 x 7
x = 2 x 7
x = 14.
The value of x that makes the triangle similar is of x = 14.

Answer:
This is an enlargement.
Step-by-step explanation:
This is an enlargement.
A reduction would be smaller
A rotation would be changing the angle and a reflection would be a mirror image
Step-by-step explanation:
(a) 15% of $ 6000 = 5/100 × 600= &30
value after x years =$ 6000 -$ 30x
(b) value after 6 years = $ 600 - & 180 = $ 5820
Hello from MrBillDoesMath!
Answer:
152 in^2
Discussion:
Surface area =
2 (area of side triangle + area of rectangle face) +
area of bottom rectangle
= 2 ( (1/2) 6*4 + 5*8 ) + 8*6
= 2 ( (1/2) 24 + 40 ) + 48
= 2 (12 +40 ) + 48
= 2(52) + 48
= 104 + 48
= 152
Thank you,
