Answer:
the answer is 0 to 1 and 3 to 4
Answer:
C
Step-by-step explanation:
Okay, so this is what I came to. I think that you might need to look through the placement of the problem again and your x's, but other than that, here it is!
Step 1: Simplify both sides of the equation.<span>425=<span><span>−<span>250<span>x2</span></span></span>+<span>6250x
</span></span></span>Step 2: Subtract -250x^2+6250x from both sides.<span><span>425−<span>(<span><span>−<span>250<span>x2</span></span></span>+<span>6250x</span></span>)</span></span>=<span><span><span>−<span>250<span>x2</span></span></span>+<span>6250x</span></span>−<span>(<span><span>−<span>250<span>x2</span></span></span>+<span>6250x</span></span>)</span></span></span><span><span><span><span>250<span>x2</span></span>−<span>6250x</span></span>+425</span>=0
</span>
Step 3: Use quadratic formula with a=250, b=-6250, c=425.<span>x=<span><span><span>−b</span>±<span>√<span><span>b2</span>−<span><span>4a</span>c</span></span></span></span><span>2a</span></span></span><span>x=<span><span><span>−<span>(<span>−6250</span>)</span></span>±<span>√<span><span><span>(<span>−6250</span>)</span>2</span>−<span><span>4<span>(250)</span></span><span>(425)</span></span></span></span></span><span>2<span>(250)</span></span></span></span><span>x=<span><span>6250±<span>√38637500</span></span>500</span></span><span><span>x=<span><span>252</span>+<span><span><span><span>110</span><span>√15455</span></span><span> or </span></span>x</span></span></span>=<span><span>252</span>+<span><span><span>−1</span>10</span><span>√15455

Given data:
Volume of the prism A = 2080
Let us find the ratio of the volume of prisms given in the diagram:
Since the condition is:
The volume of Prism A = The volume of Prism B
Therefore,
The ratio of their volumes should be 8.
Since Volume of A = 2080
Plug-in the value, you would get:
Ans: Volume of B = 260
Answer:
i) 9
ii) 19 pens, 7 pencils, 3 erasers
Step-by-step explanation:
i) 171 = 3² x 19
63 = 3² x 7
27 = 3³
Highest Common Factor/HCF (171, 63, 27) = 3² = 9
Largest no. of bags = 9
ii) In each bag,
No. of pens = 171 / 9 = 19
No. of pencils = 63 / 9 = 7
No. of erasers = 27 / 9 = 3
