What is the approximate 47? Give your answer and explain why it is correct. HELP
Answers
Answer:
7
Step-by-step explanation:
7 is approximate to [tex]\sqrt{47}[/tex] because 7 is [tex]\sqrt{49}[/tex], and 49 is close to 47
Answer:
Step-by-step explanation:
[tex]6^{2} =36\\7^2=49\\therefore,6< \sqrt{47} <7,\\6.5^2=42.25,\\therefore,6.5< \sqrt{47} <7,\\6.75^2=45.5625\\therefore,6.75< \sqrt{47} <7\\6.85^2=46.9225\\therefore,6.85< \sqrt{47} <7\\6.9^2=47.61\\therefore,6.85< \sqrt{47} <6.9[/tex]

Here are 7 7 same-sized cups filled with water which will be used for watering plants. Fred used 1 3 3 1 of each cup of water. Janice used 1 4 4 1 of each cup of water. Approximately how many cups of water remain?
Answers
Answer:
2 11/12
Step-by-step explanation:
total amount fred used = 1/3 x 7 = 7/3
total amount Janice used = 1/4 x 7 = 7/4
total amount used =
7/3 + 7/4
(28 + 21) / 12 = 49 / 12 = 4 1/12

A factory that makes computer monitors produced 247 monitors during 5 working days. Which is closest to the number of working days that should be allowed to fill an order for 1,000 monitors?
Answers
Answer:20 days
Step-by-step explanation:247/5=49.4
That’s the amount they monitor per day 49.4
Then they wanted to monitor 1000
So 1000/49.4=20.24(estimate)
20 days is the answer
I’m not 100% sure it might be 21 because it will take 21 days to monitor at LEAST 1000

Answer: D. Pansy will take $25 per week from her account
Step-by-step explanation:
Based on the information given in the question, the true statement is that Pansy will take $25 per week from her account. This is represented by $25x.
For example, if the number of weeks that he used is 8 weeks. The amount in the savings account will be:
y = $25x + $500
y = $25(8) + $500
y = $200 + $500
y = $700

Vikram has a bucket of three different racquetballs, one blue, one black, and one red. He wants to test each ball to see how well they bounce. He reaches into the bucket and removes one ball without looking. He hits the ball against the wall, catches it, and then drops it back into the bucket. He repeats this process twice more, each time choosing a ball without looking.
Part A:
What is the probability that Vikram hits the blue ball, then the black ball, and then the red ball?
Answer:
Part B:
If Vikram does not drop the balls back into the bucket after he hits them, what is the probability that Vikram hits the blue ball, then the black ball, and then the red ball?
Answer:
Answers
Answer:
A) 33.3%
B) 50 %
Step-by-step explanation:
A) if there are 3 balls always in the bucket you need to see what one balk represent one ball is 1÷3 which is 0.33 so by knowing that if Vikram drops the ball back into the bucket after the hit there would be a 33 % chance he will chose the same or a different ball in order.
B)if he won't put the ball back in the bucket there will be only 2 balls felt so 1÷2 = 0.5 so there is a 50 % chance of Victor getting the balls in the correct order

Answer:
x = y = 15[tex]\sqrt{2}[/tex]
Step-by-step explanation:
Using the sine ratio and the exact value
sin45° = [tex]\frac{\sqrt{2} }{2}[/tex] , then
sin45° = [tex]\frac{opposite}{hypotenuse}[/tex] = [tex]\frac{x}{30}[/tex] = [tex]\frac{\sqrt{2} }{2}[/tex] ( cross- multiply )
2x = 30[tex]\sqrt{2}[/tex] ( divide both sides by 2 )
x = 15[tex]\sqrt{2}[/tex]
The triangle is isosceles (45- 45- 90) , then 2 legs are congruent, so
y = x = 15[tex]\sqrt{2}[/tex]

Given:
[tex]AB=6\ BC=r,\ CD=r,\ AD=12[/tex].
To find:
The value of r.
Solution:
We have,
[tex]AB=6\ BC=r,\ CD=r,\ AD=12[/tex].
We know that the radius is perpendicular to the tangent at the point of tangency
AD is the tangent and CD is the radius. So, CD is perpendicular to AD at point D, i.e., [tex]m\angle D=90^\circ[/tex].
Using Pythagoras theorem, we get
[tex]AC^2=AD^2+CD^2[/tex]
[tex](6+r)^2=12^2+r^2[/tex]
[tex]36+12r+r^2=144+r^2[/tex]
[tex]12r=144+r^2-36-r^2[/tex]
On further simplification, we get
[tex]12r=108[/tex]
[tex]r=\dfrac{108}{12}[/tex]
[tex]r=9[/tex]
Therefore, the value of r is 9.

Answer:
16 units
Step-by-step explanation:
For a right triangle, a²+b²=c², where a and b are leg lengths, and c is the hypotenuse. Given one leg length and the hypotenuse, we can find the other leg length by plugging in our given information:
a²+b²=c²
12²+b²=20²
144+b²=400
b²=256
b=16
Therefore, the missing leg length is 16 units.
