The circumference of a circular tablecloth is 160 inches, Will the tablecloth cover
a table with diameter 52 inches?
Answer:
D= 50.92 in
Step-by-step explanation:
Step one:
Given data
The circumference of a circular tablecloth is 160 inches
We want to know if the circular table cloth can also cover a table of diameter 52 in
Step two:
let us solve for the diameter of the table cloth given that the circumference is
160in
circumference
[tex]C= 2 \pi r[/tex]
[tex]160= 2*3.142*r\\\\160= 6.284r[/tex]
divide both sides by 6.284
[tex]160/6.284= r\\\\r=25.46 in[/tex]
The diameter of the table cloth is
[tex]=25.46*2\\\\=50.92 in[/tex]
The Table cloth cannot cover the table because the diameter of the cloth is not up to the diameter of the table

Answer:
Me and my massive brain, among other massive things of mine, believe it to be -1
Step-by-step explanation:
The value of the function F(g(x) will be equal to (7 / 2).
What is a function?A function is defined as the expression that set up the relationship between the dependent variable and independent variable.
Given functions are:-
f(x)=3x-7 g(x)= x +(1/x-1)The function F(g(x) is written as :-
F(g(x) = 3 [ x + ( 1 / ( x-1 )) -7 ]
F(g(x) = 3 [ (3 + (1/2) - 7 ]
F(g(x) = 3 (7 / 2 ) -7
F(g(x) = ( 21/2) - 7
F(g(x) = ( 21-14 ) ( 2 )
F(g(x) = ( 7/2 )
Therefore the value of the function F(g(x) will be equal to (7 / 2).

Gary Sanchez struck out 112 times in 350 at bats. What PERCENTAGE of his at-bats were strike outs?
Given :
Gary Sanchez struck out 112 times in 350 at bats.
To Find :
Percentage of his at-bats were strike outs.
Solution :
We know, percentage hits is given by :
[tex]Percentage = \dfrac{\text{Number of time bats were strike out}}{\text{Total number of bats}}\times 100 \ \%[/tex]
Putting all given values in above equation, we get :
[tex]Percentage = \dfrac{112}{350}\times 100\ \%\\\\Percentage = 32\ \%[/tex]
Hence, this is the required solution.

What is the value of a if a is equal to a×a×a=a+a+a
Answer:
a = ±sqrt(3)
Step-by-step explanation:
a×a×a=a+a+a
Simplifying each side
a^3 = 3a
Divide each side by a
a^3 /a = 3a/a
a^2 = 3
Take the square root of each side
sqrt(a^2) = ±sqrt(3)
a = ±sqrt(3)
Answer:
nope its not equal
a×a×a=a³, but a+a+a=3a
so, a³≠3a

Declan wants to mail 28 drawings to his Grandma. If he can fit 3 drawings in each envelope, how many envelopes will he need to mail all the drawings
Answer:
10 envelopes
Step-by-step explanation:
What we know:
- There are 3 drawings for each envelope
- There are 28 drawings in total
To find out the number of envelopes Declan would need, we divide 28 by 3 (check the picture attached).
28÷3=9 R1
28 divided by 3 gives us 9 with a remainder of 1, which means if Declan had 9 envelopes, he would be able to fit 3 drawings in each with 1 drawing left over. He would need a 10th envelope to use for the last drawing.
Therefore, Declan would need 10 envelopes to mail all the drawings to his grandma.
I hope this helps! Happy holidays :)

Complete question is;
A group of biologists is surveying the mice population in a forest. The equation n=75⋅3t gives the total number of mice, n, t years since the survey began.
what does the number 3 mean in this situation.
1. the common difference
2. the total population
3. the common ratio
4. the slope
Answer:
3 is the common ratio
Step-by-step explanation:
We are given that the equation; n = 75⋅3^(t) gives the total number of mice, n, t years since the survey began.
Normally, formula when calculating population growth takes an exponential function;
n = n_o(e^(rt))
Or in this our case, it can be written as;
n = n_o((e^(r))^(t))
Comparing this with n = 75⋅3^(t), we can see that e^(r) = 3
Where r is the growth rate.
e is exponential constant.
Thus, we can say that 3 is the common ratio

In AWXY, X = 1.2 cm, ZX=45° and Y=108°. Find the length of w, to the nearest 10th
Answer:
The length of w is 0.8 cm
Step-by-step explanation:
In Δ WXY
x is the opposite side to ∠X
w is the opposite side to ∠W
y is the opposite side to ∠Y
∵ m∠X = 45°
∵ m∠Y = 108
∵ The sum of the measures of the interior angle of a triangle is 180°
∴ 45 + 108 + m∠W = 180
→ Add the like terms in the left side
∵ 153 + m∠W = 180
→ Subtract 153 from both sides
∴ m∠W = 27°
Now we can use the sine rule to find the length of w
∵ [tex]\frac{w}{sin(W)}[/tex] = [tex]\frac{x}{sin(X)}[/tex] = [tex]\frac{y}{sin(Y)}[/tex]
→ Use the first 2 ratios to find w
∵ x = 1.2 cm
∵ [tex]\frac{w}{sin(27)}[/tex] = [tex]\frac{1.2}{sin(45)}[/tex]
→ By using cross multiplication
∴ w × sin(45) = 1.2 × sin(27)
∴ w sin(45) = 1.2 sin(27)
→ Divide both sides by sin(45)
∴ w = 0.7704474263
→ Round it to the nearest tenth
∴ w = 0.8 cm
∴ The length of w is 0.8 cm
Solve the equation. Round the answer to the nearest tenth.

Anton has 3 8/7 cups of syrup that he serves with his pancake orders. He uses 2/3 cup of syrup for each pancake order. What is the maximum number of complete pancake orders that Anton can serve with the syrup he has?
Answer:
6 3/14 pancake order s
Step-by-step explanation:
The question above is calculated as:
2/3 cup of syrup = 1 pancake order
3 8/7 cups of syrup = x
Cross Multiply
2/3 × x = 3 8/7 × 1
x = 3 8/7 ÷ 2/3
x = 29/7 ÷ 2/3
x = 29/7 × 3/2
x = 87/14
x = 6 3/14 order
The maximum number of complete pancake orders that Anton can serve with the syrup he has is 6 3/14 pancake orders
