Answer:
w=20/9 or w=2 2/9
Step-by-step explanation:
Multiply each side by 5/3. Then reduce the numbers with the greatest common divisor which is 5 do the same with 3. then multiply the fractions and thus the answer of 20/9 you can simplify the improper fraction if you want the answer is still the same. Hope this helps.
Answer:
Step-by-step explanation:
7/10 × 4/21
1/5 *2/3 =2/15
reduce them down
We have by the intermediate value theorem that if a continuous function takes values both above and below zero at 2 points, there is a zero of the function in-between. We have that polynomials are continues. Let's calculate f(-6) and f(-5). f(-6)=-36 while f(-5)=-1. Thus, we cannot conclude that there is a root between them.
F(-2)=8, f(-1)=-1, so there is a flip; a zero must exist between them.
F(1)=-1, f(2)=20, so again there is a change of signs.
f(-5)=-1, f(-4)=14 so there is a root still.
We have that the only choice that does not have a root between the integers is choice a.
Answer:
8784 mm²
Step-by-step explanation:
15 cm = 150 mm
Surface area
= 2( 150 x 12) + 2(150 + 12)x16
= 3600 + 5184
= 8784 mm²
