Answer:
Step-by-step explanation:
X^2+Y^2=16
X^2+4X^2=16
5X^2=16
X^2=16/5
X=+- SQRT(16/5)
X=+- 4SQRT(5)
DISREGARD THE -4SQRT(5) BECAUSE WE ARE DEALING WITH THE FIRST QUADRANT
Answer:
4
Step-by-step explanation:
2-(-2)=2+2=4
Answer:
492 gallons
Step-by-step explanation:
Total gallons of water collected = 4212
Gallons used for watering of plants = 114
Remaining gallons = 4212 - 114
= 4098
She uses 12% of the remaining water to was her laundry.
So that, gallons of water used to wash her laundry = 12% of 4098
= 
× 4098
= 491.76
≅ 492
She uses 492 gallons to wash her laundry.
Any whole number is an integer but here are some examples: 1,5, 8, 97.
Answer:
Surface area of net = 310 cm²
Step-by-step explanation:
Given:
Dimension of two same rectangle = 11 cm by 9 cm
Dimension of single rectangle = 11 cm by 7 cm
Height of two triangle = 5 Cm
Base of two triangle = 7 Cm
Find;
Surface area of net
Computation:
Surface area of net = Surface area of two same rectangle + Surface area of single rectangle + Surface area of two same triangle
Surface area of net = 2[l x b] + [l x b] + 2[(1/2)(b)(h)]
Surface area of net = 2[11 x 9] + [11 x 7] + 2[(1/2)(7)(5)]
Surface area of net = 198 + 77 + 35
Surface area of net = 310 cm²
