Answer:
A. 82.9 yds
Step-by-step explanation:
The missing leg of the right triangle can be found from ...
w²+ l² = d²
w² + 125² = 150²
w² = 150² -125² = 22500 -15625 = 6875
w = √6875 ≈ 82.9
The width of the field is about 82.9 yards.

Answer:
1/3 x 1/3 = ?
3 x 3 = ?
Step-by-step explanation:
3 x 3 = 9 yesyes
1/3 x 1/3 = 1/9
now we add, right? 9/1 ( same as 9 ) + 1/9 = ?
does it want it in fraction, decimal, or whole?
Answer:
9 1/9 is the answer
Step-by-step explanation:
1/3 to the power of 2 becomes 1/9
3 to the power of 2 becomes 9
[tex]\frac{1}{9} + 9[/tex]
whole numbers always go over a 1
[tex]\frac{1}{9} + \frac{9}{1}[/tex]
make 9/1 have the same denominator as 1/9 by multiplying the top and bottom with 9
[tex]\frac{1}{9} + \frac{81}{9}[/tex] [tex]= \frac{82}{9}[/tex]
the simplify 82/9
[tex]\frac{82}{9} = 9\frac{1}{9}[/tex]
The universal set is U = {Monday, Tuesday, Wednesday, Thursday, Friday, Saturday, Sunday}. If A = {Monday, Tuesday,Wednesday, Thursday, Friday} and B = {Friday, Saturday, Sunday}, find the indicated set.
A intersect B '
Answer:
{Monday, Tuesday, Wednesday, Thursday}
Step-by-step explanation:
First we need to get the complement of B i.e B'
B' are the set in the Universal set but that are not in B
B' = {Monday, Tuesday, Wednesday, Thursday}
A= {Monday, Tuesday, Wednesday, Thursday, Friday}
A intersect B ' are the days of the week that are common to both sets;
A intersect B ' = {Monday, Tuesday, Wednesday, Thursday}

Rewrite the equation of the line 5y = -1/4x - 6 in standard form
Answer:
D
Step-by-step explanation:
The equation of a line in standard form is
Ax + By = C
Given
5y = - [tex]\frac{1}{4}[/tex] x - 6 ( multiply through by 4 to clear the fraction )
20y = - x - 24 ( add x to both sides )
x + 20y = - 24 → D
So, Christian has a collection of 18 shark teeth. He identified them as 6 tiger shark teeth, 8 sand shark teeth, and the rest as bull shark teeth, I don’t get the 2nd question, can anyone help??
Answer:
So, the question means that if we add the number of tiger shark teeth and the sand shark teeth and subtract it from the total number of teeth, we will get the number of bull shark teeth. And, the number of bull shark teeth is 4.
Step-by-step explanation:
So, the question means that if we add the number of tiger shark teeth and the sand shark teeth and subtract it from the total number of teeth, we will get the number of bull shark teeth.
Since Christian has 18 shark teeth, and 6 are tiger shark teeth, 8 are sand shark teeth and the rest are bull shark teeth.
Let x represent the number of bull shark teeth.
So, total number of shark teeth = number of tiger shark teeth + number of sand shark teeth + number of bull shark teeth.
18 = 6 + 8 + x
18 = 14 + x
subtracting 14 from both sides, we have
18 - 14 = 14 - 14 + x
4 = 0 + x
4 = x
x = 4
So, the number of bull shark teeth is 4.

Step-by-step explanation:
x is inversely proportional to the square root of y
When x = 12, y = 9
Find the value of x when y= 81
Answer: 4
Step-by-step explanation:
The formula for inverse proportion is x = k / y. Since x is inversely proportional to the square root of y. This will be:
x = k / ✓y
When x = 12, y = 9
We have to calculate the constant of proportionality, k which will be:
12 = k / ✓9
12 = k / 3
k = 12 × 3
k = 36
To find the value of x when y = 81 will be:
x = k / ✓y
x = 36 / ✓81
x = 36 / 9
x = 4
Therefore, x = 4 when y = 81.

Hello Solving Equations Puzzle
Answer:
Pink Trapezium = 30 as 30 x 1 = 30
Purple Diamond = 2 as 2 x 2 = 4
Green Moon = 7.5 as it shares the line with 4 it goes 4 x 7.5 = 30
The weight of the line is dividing line just the same as multiple when we find the numbers from dividing. But work out 2 x 2 first. then use that number to divide into 30 to find 7.5.
When we show the values see below. We have 30 also for the second line so both lines are equivalent
Step-by-step explanation:
I would multiply as addition is just too easy.
Pink Trapezium is 1 x 30 = 30 = 30/1 = 30 value
Purple diamond = 2 x 2 = 4 = 4/2 = 2 value
Green Moon is 30/4 = 7.5 value
The mean of the numbers 22,18,(2y+1),10 and 20 is 15.
find the median.
Answer:
Median is 18
Step-by-step explanation:
Firstly you have to fine y by using your mean
Therefore, 22+18+(2y+1)+10+20 divide it by the number of the mean that is the sum of the number divide by the total number of the mean which is 5 =15
22+18+2y+1+10+20 over 5 =15
71+y over 5 =15
Cross multiple
71+y=75
y=4
22,18,9,10, 20
Rearrange
9,10,18,20,22
The median is 18
