Answer:
he cross section becomes smaller but stays a trapezoid.
Step-by-step explanation:
First, we want to ask "What number divided by 7 <em>is </em>800?" That'll give us a jumping off point to answer the rest of the question.
If dividing some number by 7 gets us 800, that means that <em>multiplying </em>800 by 7 should get us back that number. We find that 800 x 7 = 5600. The first number higher than 5600 is 5601, which, when divided by 7, gets us about 800.14, a number greater than 800. So the lowest whole number that makes the inequality ? ÷ 7 > 800 work is 5601.
Rewrite the equation:
-2x^2 - 3x + 8 = 0
2x^2 + 3x -8 =0
Where a=2, b=3 and c=-8
Then b^2 - 4ac = 3^2 - 4(2)(-8) = 9 + 64 = 73
A positive discriminant implies that the equation has two different real solutions.
Answer: the discriminant is 73, so the equation has 2 real solution
Answer:
The ratio of her savings to expenditure <u>1 : 7</u>.
Step-by-step explanation:
Given:
Neelam's annual income is Rs. 288000.
Her annual savings amount to Rs. 36000.
Now, to get the ratio of her savings to her expenditure:
So, we get the expenditure first:
Expenditure = Income - Savings.
Expenditure = 288000 - 36000 = Rs. 252000.
Now, <em>the ratio of savings to expenditure:</em>
Thus, Savings:Expenditure = 1:7.
Therefore, the ratio of her savings to expenditure 1 : 7.
