Title:
<h2>The answer is
.</h2>
Step-by-step explanation:
Let the building contractor bought 1000 cement in total.
70% of 1000 = 700 cements were from A and (1000 - 700) = 300 cements were from B.
The number of undamaged bag from A was 95% of 700 = 
and the number of undamaged bags from B was 70% of 300 = 
.
Total undamaged bags were (665 + 210) = 870.
The probability that an undamaged bag is from A is 
.
Answer:
a) 32100 millimeters
c) 3,210 centimeters
d)3.21 decameters
Step-by-step explanation:
To find which measurements are equal 321 decimeters, we will follow the steps below:
<u>changing 321 decimeters to millimeters</u>
let x be 321 decimeters in millimeters
1 decimeter = 100 millimeters
321 decimeters = x
cross - multiply
x = 321× 100
x = 32100 millimeters
hence, 321 decimeters = 32100 millimeters
<u>converting 321 decimeters to centimeters</u>
let y be 321 decimeters in centimeters
1 decimeters = 10 centimeters
321 decimeters = y
cross-multiply
y = 321× 10
y = 3210 centimeters
Thus, 321 decimeters = 3210 centimeters
<u>converting decimeter to decameters</u>
let z represent 321 decimeters in decameters
1 decameter = 100 decimeter
z = 321 decimeter
cross-multiply
100 z = 321
divide both-side by 100
100z/100 = 321/100
z=3.21 decameters
therefore, 321 decimeters = 3.21 decameters

Step-by-step explanation:
<u>Step 1: Define Systems</u>
-24x - 4y = -164
y = 41 - 6x
<u>Step 2: Solve for </u><em><u>x</u></em>
- Substitute in <em>y</em> [1st Equation]: -24x - 4(41 - 6x) = -164
- [Distributive Property] Distribute -4: -24x - 164 + 24x = -164
- [Addition] Combine like terms: -164 = -164
Here we see that -164 does indeed equal -164.
∴ We have an infinite amount of solutions.
1/2, 4/8, etc. Because they all equal to one half. <span />
Answer:
-4.5
Step-by-step explanation:
I added 3.25 and .5=3.75. Then i did 0.25*-6=1.5. -1.5+3.75=2.25. 2.25*2=-4.5
