Answer:
A. 3/10
Step-by-step explanation:
So the ratio is saying 2 units to 3 units. What represents 1 unit when 1/5 is two units? We cut it in half which is 1/10.
Now we have 1 unit so we can easily find three by multiplying by three, or even just adding three together. So that's 3/10.
let me knowif you don't quite get it.
We can either convert to standard form first or convert to a common multiplier, kinda like a common denominator. The latter makes more sense if they wanted the result in scientific notation, but let's do it that way anyway.
a)
4.5 × 10⁴ + 3.8 × 10³ = 45 × 10³ + 3.8 × 10³ = 48.8× 10³ = 48,800
Answer: 48,800
b)
4.5 × 10⁴ - 3.8 × 10³ = 45 × 10³ - 3.8 × 10³ = 41.2× 10³ = 41,200
Answer: 41,200
c)
7.2 × 10⁻³ + 6.3 × 10⁻² = 7.2 × 10⁻³ + 63 × 10⁻³ = 70.2 × 10⁻³
= 7.02 × 10⁻² = 0.0702
Answer: 0.0702
Answer:
<h3>83°</h3>
Step-by-step explanation:
Given the parameters
m2 ROC = 31° and
m2 COL = 52°
According to the diagram in the attachment;
m2 ROL = m2 ROC + m2 COL
Substitute the given values into the expression as shown;
m2 ROL= 31°+52°
m2 ROL = 83°
Answer:
z= 104
y=76
x=76
Step-by-step explanation:
z+76= 180. solve for z
z=x
y=76
