Answer:
20cm
Step-by-step explanation:
for the triangle:
Perimeter = 30cm
a + a + a = 30
3a = 30
hence a = 10cm
For the rectangle:
Perimeter = 30cm
a + a + b + b = 30
but a = 10cm
10 + 10 + b + b = 30
20 + 2b = 30
2b = 10
hence b = 5cm
Perimeter of square = b + b + b + b
= 5 + 5 + 5 + 5 = 20cm
Answer:
8x - 14 = 5x + 34 (alternate exterior angles)
8x - 5x = 34 + 14
3x = 48
x = 48/3
x = 16
5y + 16 + 8x - 14 = 180 (linear pair)
5y + 16 + 8(16) - 14 = 180
5y + 16 + 128 - 14 = 180
5y + 130 = 180
5y = 180 - 130
5y = 50
y = 50/5
y = 10
∠ (8x - 14) = 114 [(8 × 16 -14)=114]
∠ (5x + 34) = 114 [(5 × 16 +34)=114]
∠ (5y + 16) = 66 [(5 × 10 +16)=66]
hope this helps you!
30% times by x is 9. (x is the number we’re trying to figure out) another way to put this equation is 30/100 times x = 9. now let’s multiply both sides by 100 and divide both sides by thirty. we have x = 9 times 100/30. so the answer is 30. the puppy’s full weight is 30 pounds. hope this helps :)
Answer:
625
Step-by-step explanation:
Convert 15300 to a percent,
We can convert it to it's lowest fraction,
120, and to find the percent just multiply it by 5 on top and bottom,
120 ×5×5
which equals, 5100
Then take the percent as a decimal, 0.5 and multiply it by 12500,
12500×0.5 which would give you: 625
