The circumference of a circle is 22 meters. What is the approximate diameter of the circle?
Answer:
7
Step-by-step explanation:
to find the circumference of a circle the equation is C=πd where C is circumference, d is diameter, and using 3.14 for π
once we plug in the known information we are left with
22=(3.14)d
all that's left is to solve for d
22=(3.14)d
22/3.14=(3.14)/3.14 d
7=1d
7=d

The library has 157 chairs and 14 tables. If the same number of chairs is placed at each table, how
many chairs can be placed at each table? Will there be any extra chairs? If so, how many?
11 chairs at each table. (157/14 = 11.214...)
There will be 3 chairs left over. (14x11 = 154 157-154 = 3)
Answer:
total chair = 157 and total chair = 14 each table would have 18 chair and 5 chair would be extra

Answer:
b = 5.7
A = 51.1°
B = 38.9°
Step-by-step explanation:
a = 7
c = 9
✔️Find b using Pythagorean theorem:
b = √(9² - 7²) ≈ 5.7
✔️Find A using trigonometric function:
Reference angle = A
Opposite = a = 7
Hypotenuse = c = 9
Apply SOH:
[tex] sin(A) = \frac{Opp}{Hyp} [/tex]
[tex] sin(A) = \frac{7}{9} [/tex]
[tex] A = sin^{-1}(\frac{7}{9}) [/tex]
A = 51.0575587° = 51.1°
✔️B = 180 - (90 + 51.1) (sum of triangles)
B = 38.9°

Marco is coaching football 24 out of 30 days in June which decimal is equivalent to the fraction of days until he coach football
Answer:
Since the fraction of this is very obviously 24/30, here's how you can get a decimal out of that:
First, you simplify that fraction.
24/30 = 4/5, since 5x6 is 30 and 6x4 is 24
Now, it's pretty easy to convert 4/5 into a decimal.
This is how I like to do it. You re-convert the fraction one step higher, so it's 8/10, and you just turn it into 0.8, since it's all out of 10.

Answer:
[tex]\bf\Huge 65 [/tex]
Step-by-step explanation:
Given that :A publishing house is selling subscriptions to magazines for 10% off the original price.If a subscription to Time Magazine costs $58.50 with the discount.to find :what was the original price ?explanation :finding the original price
⟼ 100 •/• - 10 •/• = 90•/•
⟼ 90.•/• = $ 58•50
⟼ 1 •/• = $ 58•50 / 90
⟼ 100 •/• = $ 58•50 / 90 × 100
⟼ 100 •/• = $ 5850 / 90
⟼ 100 •/• = $ 585 / 9
⟼ 100 •/• = $ 65.
∴ the original price is $ 65.

Think About the Process If you solve the linear system by adding to eliminate p, which step could you do first? Solve for p and q.
2p +39 = 7
3p + 59 = 10
Which step could you do first?
O A. Multiply the first equation by - 3 and the second equation by - 2.
O B. Multiply the first equation by 3 and the second equation by 2.
O c. Multiply the first equation by - 3 and the second equation by 2.
OD. Multiply the first equation by - 2 and the second equation by 3.
The solution is
(Type an ordered pair.)
Answer:
(23, -1)
Step-by-step explanation:
I think you meant 2p + 39q = 7 , & 3p + 59q = 10
You would do C first, because that will get rid of the P's.
---> -6p - 117q = -21
---> 6P + 118q = 20
Now we get q=-1
If we plug it into the first equation, we get 2p + 39(-1) = 7
Therefpre, 2p - 39 = 7. This means that 2p = 46.
Therefore, p = 23

it's how many times 0.08 goes into 3.16
Answer: 2.53
Step-by-step explanation:
you divide it 0.08÷3.16 and like it would give you a large answer but just multiply it by 100 so you will get 2.53 and if you divide that by 3.16 it would give you 0.08 so the answer is "2.53"
0.08 ÷ 3.16 =0.0253164557 x 100= 2.53

Find the future value of #8000 at 12percent for 3 years
Answer:
Future value using simple interest = $10,880
Future value using Compound interest = $11,240 (Approx.)
Step-by-step explanation:
Given:
Principal Amount = $8,000
Rate = 12% = 0.12
Number of year = 3
Find:
Future value
Computation:
Future value using simple interest
Future value = P + (P)(R)(T)
Future value = 8,000 + (8,000)(0.12)(3)
Future value = 8,000 + 2,880
Future value using simple interest = $10,880
Future value using Compound interest
Future value = P[1+r]ⁿ
Future value = 8,000[1+0.12]³
Future value = 8,000[1.12]³
Future value using Compound interest = $11,240 (Approx.)

cos(alpha + pi/3) = (sqrt(3))/2
Answer:
α = -2 π n_1 - π/2 for n_1 element Z
or α = -2 π n_2 - π/6 for n_2 element Z
Step-by-step explanation:
Solve for α:
sin(-α + π/6) = sqrt(3)/2
Hint: | Eliminate the sine from the left hand side.
Take the inverse sine of both sides:
-α + π/6 = 2 π n_1 + (2 π)/3 for n_1 element Z
or -α + π/6 = 2 π n_2 + π/3 for n_2 element Z
Hint: | Look at the first equation: Isolate terms with α to the left hand side.
Subtract π/6 from both sides:
-α = 2 π n_1 + π/2 for n_1 element Z
or -α + π/6 = 2 π n_2 + π/3 for n_2 element Z
Hint: | Solve for α.
Multiply both sides by -1:
α = -2 π n_1 - π/2 for n_1 element Z
or -α + π/6 = 2 π n_2 + π/3 for n_2 element Z
Hint: | Look at the second equation: Isolate terms with α to the left hand side.
Subtract π/6 from both sides:
α = -2 π n_1 - π/2 for n_1 element Z
or -α = 2 π n_2 + π/6 for n_2 element Z
Hint: | Solve for α.
Multiply both sides by -1:
Answer: α = -2 π n_1 - π/2 for n_1 element Z
or α = -2 π n_2 - π/6 for n_2 element Z
What is the value of y?
Answer:
- 1
Step-by-step explanation:
( x, y ) = ( 2, y )
x = 2
2x - 8y = - 4
Divide 2 on both sides,
( 2x / 2 ) - ( 8y / 2 ) = - 4 / 2
x - 4y = - 2
Substitute x = 2,
2 - 4y = - 2
- 4y = - 2 - 2
- 4y = - 4
y = - 4 / - 4
y = - 1
Find the value of x
Answer:
66
Step-by-step explanation:
EHG is a straight line so it is 180°.
You already know the value of FHG, so you can find the value of 2x.
180° = 48° + 2x
2x = 180° - 48°
= 132
x = 132° ÷ 2
= 66
Answer:
66 should be the answer.
Step-by-step explanation:
2x + 48 = 180
2x + 48 - 48 = 180 - 48
2x = 132
2x ÷ 2 = 132 ÷ 2
x = 66

Will mark brainliest please help Debbie notices that the amount owed on her monthly heating bill varies inversely with the average outdoor temperature. Last month the average outdoor temperature was 35°F, and her bill was $210. If this month's average outdoor temperature is 40°F, what can Debbie expect her bill to be?
Answer:
The bill is $1837.5
Step-by-step explanation:
Given
[tex]B = Bills[/tex]
[tex]T = Temperature[/tex]
[tex]B\ \alpha\ \frac{1}{T}[/tex] --- The variation
T = 35; when B = 210
Required
Find B when T = 40
[tex]B\ \alpha\ \frac{1}{T}[/tex]
Express as an equation
[tex]B = \frac{k}{T}[/tex]
Make k the subject
[tex]k = BT[/tex]
T = 35; when B = 210
[tex]k = 35 * 210[/tex]
[tex]k = 7350[/tex]
When T = 40, we have:
[tex]k = BT[/tex]
[tex]7350 = B * 40[/tex]
Make B the subject
[tex]B = \frac{7350}{4}[/tex]
[tex]B = 1837.5[/tex]
