Answer:
a = -⅓
b = 3
Step-by-step explanation:
-3a + b = 4
3a + b = 2
b = 4 + 3a = 2 - 3a
6a = -2
a = -2/6
a = - ⅓
-> b = 4 + 3(-⅓)
b = 4 - 1
b = 3
If we are scaling up the surface area by a factor of 10 means that the two dimensions of area are each being increased by 10 times the original size. Therefore, the surface area is increased by a factor of 10 x 10, or by a factor of 100.
Answer:
Step-by-step explanation: 100 divided by 20 is 5 therefore, each question is worth 5%. take how many questions she got right and multiply by 5. then determine if her score is less than or greater then 90%.
Answer:
17
Step-by-step explanation:
2c + d^3 - 3e +4f
=2(3) + (5^2) - 3(6) + 4(1)
=6+25-18+4
=17
Answer:
The new volume of an enlarged tank is 4000m³
Step-by-step explanation:
The scale factor has to be multiplied by the width, length and height so we will have to multiply it 3 times
h * w * l = 32 m³
(h*5) * (w*5) * (l*5)
if we rearrange the multiplications
(h * w * l) * 5 *5 * 5 =
v * 5 * 5 * 5 =
32m³ * 5 *5 *5 = 4000m³
