Answer:
x= -2/9
Step-by-step explanation:
2(x-2)/5=4x
2(x-2)=4x*5
2(x-2)=20x
x-2=20x/2
x-2=10x
-2=10x-x
9x= -2
x= -2/9
Answer:
5229 mm³
Step-by-step explanation:
Volume of square pyramid

b = base length = 25 mm
H = height
We have to find 'H' using Pythagorean theorem,
slant height (hypotenuse) = 28 mm
leg₁ = base length ÷ 2 = 25÷2 = 12.5
leg₂ = H
H² + (12.5)² = 28²
H² = 784 - 156.25
= 627.75

H = 25.01 mm

= 5229 mm³

Answer:
100 times
Step-by-step explanation:
multiples of 3 on a number cube are 3 and 6
probability of rolling a '3' or '6' is 1/6 + 1/6 = 2/6 or 1/3
1/3 x 300 = 100

Answer:
The answer is negative. Answer choice B
Step-by-step explanation:
Here is the question:
-3^40(5.6/2.1)
According to order of operations, we must do -3^40 first.
Its important to note that -3^40 is different than (-3)^40. In the problem you specified, the ^40 only applies to the 3, not -3. So, first we do 3^40 which is a huge number. And then, we need to add a negative symbol to that huge number. So now we have a massive negative number multiplied by 5.6/2.1, which is obviously positive. Obviously, a negative number multiplied by a positive number is still negative. Therfore, the answer is negative.
