what is 340 to nearest hundred
Answer:
300
Step-by-step explanation:
rounding to hundreds place means you look at the middle digit in this case. If the digit is 5 or greater, then you round your first digit up, but in this case the number (4) is less than 5, we round down. By rounding down we would get 300.

what is the simplified form of the product \sqrt(3)*8\sqrt(5)
A. 9\sqrt(3)
B. 24
C. 72
D. 8\sqrt(3)
Answer: Below
Step-by-step explanation:
So let's actually make a readable expression first.
[tex]\frac{8\sqrt{3} }{\sqrt{5} }[/tex]
We first want to rationalize denominators (turning the denominator into an integer),so multiply both the numerator and denominator by sqrt(5). This method is called the big one, and doesn't change an expression since sqrt(5)/sqrt(5) = 1.
[tex]\frac{8\sqrt{3} }{\sqrt{5} } * \frac{\sqrt{5} }{\sqrt{5} } = \frac{8\sqrt{3}\sqrt{5} }{5} = \frac{8\sqrt{15} }{5 }[/tex]
This is our simplified equation.

Under an enlargement transformation point A(1,-4)is mapped onto A¹(2,5)with scale factor 3 find the center of enlargement
Answer:
(1/2, -8 1/2)
Step-by-step explanation:
The enlargement transformation maps point A to one that is 3 times as far from the center of enlargement. If the center is C, then we have the relation ...
(A' -C) = 3(A -C)
__
Solving for C gives ...
A' -C = 3A -3C
2C = 3A -A' . . . . . . . add 3C-A'
C = (3A -A')/2
Filling in the given coordinates for A and A', we find the center of enlargement to be ...
C = (3(1, -4) -(2, 5))/2 = (3 -2, -12 -5)/2 = (1, -17)/2
C = (1/2, -8 1/2)
The center of enlargement is (1/2, -8 1/2).
Quadrilateral PQRS, shown below, is a parallelogram. QS is a diagonal. PQ ║ SR and PS ║ QR.
The measure of ∠PQS is 58° degrees. What is the measure in degrees of ∠QSR?

Answer:
Writing 9/5 as a decimal using the division method. To convert any fraction to decimal form, we just need to divide its numerator by denominator. Here, the fraction is 9/5 which means we need to perform 9 ÷ 5. This gives the answer as 1.8.

Carly typed 180 words in two minutes enter the number of words Carly typed in five minutes at this rate
Answer:
the answer is 450
Step-by-step explanation:

30 POINTS FOR BOTH!!!!!!! + BRAINLIEST PRE ALGEBRA
Answer:
A = 35
B = 100
C = 25
Step-by-step explanation:
All interior angles in a triangle add up to 180 degrees.
x + 65 + x + 25 = 180
2x + 110 = 180
2x = 70
x = 35
Answer (1):
A=45 B=110
Step-by-step explanation (1):
So the inner degrees has to equal 180. So you would do this:
[tex](x+65)+x+25=180\\2x+90=180\\2x=90\\x=45[/tex]
Now substitute 45 for x and check.
[tex]45+65=110\\110+45+25= < ABC\\180= < ABC[/tex]
Answer (2):
126 degrees.
Step-by-step (2):
Like I said before, the inner degrees has to equal 180. We would write another equation. By the way, the red square is for 90 degrees.
[tex](5x-6)+3x+90=180\\8x+84=180\\96=8x\\x=12[/tex]
Now substitute 12 for x.
Also to find the anterior angle, we would add the 90 and the 3x[tex]3(12)=36\\90+36=126\\126+(5x-6)=180\\120+5x=180\\180=180[/tex]

A card is drawn from a standard deck, put aside, and then another card is drawn. What is the probability that the first card is a king and that the second card is a queen?
FRACTION FORM
Answer:
4/663
Step-by-step explanation:
Since the first card is set aside after being drawn, this is dependent probability.
There are 4 kings in 1 deck of 52 cards.
Therefore the probability of choosing a king is 4/52 = 1/13.
But after choosing 1 card from the deck, there are now 51 cards in the deck. There are 4 queens in the deck of 51 cards. Therefore the probability of choosing a queen is 4/51.
To determine the probability of choosing both, multiply the 2 probabilities.
