Answer:
(10t + u)(10u + t) = 4,930
100tu + 10t^2 + 10u^2 + tu = 4,930
101tu + 10t^2 + 10u^2 = 4,930
10t^2 + (101u)t + (10u^2 - 4,930) = 0
(101u)^2 - 4(10)(10u^2 - 4,930)
= 10,201u^2 - 400u^2 + 197,200
= 9,801u^2 + 197,200
We see that u = 5 gives 442,225.
√442,225 = 665
(10t + 5)(50 + t) = 4,930
500t + 10t^2 + 250 + 5t = 4,930
10t^2 + 505t - 4,680 = 0
2t^2 + 101t - 936 = 0
t = (-101 + √(101^2 - 4(2)(-936)))/(2×2)
= (-101 + √17,689)/4
= (-101 + 133)/4 = 32/4 = 8
So the numbers are 58 and 85.
58 + 85 = 143
Hi, This is Part B to the previos question i was offering 50 points for, Im now offering 30 points for this question. I need an answer and explanation please.
Part A ending answer: 3 cups.
1/4 of a gallon=4 cups
If I understand this correctly, there was a total of 7 cups before it was poured, adding the original answer to this one.
7 cups would equal .43 gallons, a bit less than half a gallon. If that's so, then .43 would equal 43 percent, and 43% of 128 fluid ounces would be 55.04 fluid ounces. Now the further solution, with more numbers past the decimal, it would be equal to approximately 56.
Therefore, my answer, if I understood correctly, would be 56.
Round to the nearest ten, then estimate the product. 82 x 78 = ___

Answer: The probability of not choosing a black shirt is 8/10 or 80%.
Step-by-step explanation: You add up the number of total shirts and then subtract the number of black shirts.
Answer:
20% probability of not choosing the black shirt
Step-by-step explanation:
There are 10 shirts on the shelves. Each has a 10% chance of not being chosen. There are 2 black shirts which have 10% chance each of not being chosen. if you sum it up ( 10% ×2) you will get a 20% probability of the black not being chosen.
Therefore there is a 20% probability of not choosing the black shirt

Answer:
x < 4
Graph: open dot on 4 and arrow pointing left.
Step-by-step explanation:
x + 5 < 9
Subtract 5 from both sides.
x < 4
You solved the inequality correctly.
To graph it, place an open dot on 4 and an arrow going left.
Answer:
The answer is an open circle to the left
Step-by-step explanation:
Closed circle means atleast and open means more or less than. THe equation is that 4 is more than a number. So that means it will go to the left and the circle would be open because it doesn't say at least, it's just <.
I hope this helps, I'm kind of bad at explaining.

what is the approximate radius of a sphere with a volume of 113cm cubed
a 2cm
b 4cm
c 5cm
d 3cm
Answer:
D- 3cm
Step-by-step explanation:
I looked it up
simplify
10m + – 8 + 9m + – 10m
Answer:
9m-8
Step-by-step explanation:
you need to group like terms and solve
Answer:
9m - 8
Step-by-step explanation:
We know that,
( - ) × ( - ) = ( + )
( + ) × ( + ) = ( + )
( - ) × ( + ) = ( - )
Accordingly, let us solve it now.
10m + ( – 8 ) + 9m + ( – 10m )
Solve the brackets.
10m - 8 + 9m - 10m
Combine like terms.
9m - 8
