Step-by-step explanation:
diameter = 20 inches
radius = diameter ÷ 2
radius = 20 ÷ 2
= 10 inches
circumference = 2π × radius
= 2 × 3.14 × 10
= 62.8 inches

Help please!! Solve for y.
Answer:
y = 3[tex]\sqrt{7}[/tex]
Step-by-step explanation:
The 2 right triangles inside the right triangle are similar, then ratios of corresponding sides are equal, that is
[tex]\frac{y}{9}[/tex] = [tex]\frac{7}{y}[/tex] ( cross- multiply )
y² = 63 ( take the square root of both sides )
y = [tex]\sqrt{63}[/tex] = 3[tex]\sqrt{7}[/tex]
What is the length of line segment HJ?
Answer:
b = 5√3 (units)
Step-by-step explanation:
To solve this problem, use the pythagorean theorem, where a^2+b^2 = c^2, a and b are the legs of the triangle and c is the hypotenuse.
In this case, we are finding the missing leg, and we were given one of the legs and the hypotenuse.
a^2+b^2 = c^2 (pythagorean therorm)
5^2+b^2 = 10^2 (substitute one leg and the hypotenuse)
25+b^2 = 100 (square the numbers)
b^2 = 75 (subtract 25 from both sides)
b = √75
b = √25 * √3 (factor out√75)
b = 5 * √3 (find square root of√25)
b = 5√3
Hope I was able to help! Good Luck!

Avery's mother wants to order large pizzas for Avery's birthday party. Each pizza will be cut into 8 slices. She needs enough pizza for 18 children and 5 adults. She wants each person to have 4 slices. How many pizzas does she need to order?
Answer:
She would need to order 11.5 pizzas. But of course she wouldn't order 11.5 so she'll just round up and order 12 pizzas.
Step-by-step explanation:
Take 4 pieces of pizza for each person and multiply that by how many people there are in this case 23. The answer would be 92 pieces of pizza would be needed to feed all of the 23 people. So you take 92 and divide it by 4 because each person gets 4 slices and the answer you get is 11.5. If the question is a multiple choice and it gives you the option of 11.5 then that's the answer but if its a fill in then round up to 12 pizzas because if not there will not be enough pizza for everyone.
Hope this helped! :)

Answer:
arc 1 = 108 degrees
angle 2 = 54 degrees
Step-by-step explanation:
180 - 72 = 108 (half circle -72)
draw a line from center of circle to tangent point.
this line is perpendicular to the tangent line.
all radii are equal.
then, triangle made with the new line is isosceles with two equal angles.
those angles are 36 degrees each (180 - 108 = 72, 72/2 = 36)
line drawn from center to tangent point is 90 degrees so:
90 - 36 = 54 degrees

h(7)=-60
Answer:
-60
Step-by-step explanation:
-7x7= -49

Two rival dry cleaners both advertise their prices. Store A’s prices are modeled by the expression 20x - 7, where x is the number of items brought in. Store B’s prices are modeled by the expression 4(5x + 7), where x is the number of items brought in. When do the two stores charge the same rate?
Answer:
Step-by-step explanation:
Store A price is 20x-7
store B price is 4(5x+7)
Where x represents the number of items.
Now, observe that the coefficient of both expressions is 20, because 4(5x+7)=20x+7
Remember that the coefficient of the x-variable is always the constant rate of change. Also, the given expressions can be expressed as linear functions
y=20x-7
y=20x+28
Observe that both Stores have already the same rate, which is 20.
Therefore, they have the same rate at any number of items dry cleaned.
What they have different is their initial condition, -7 and +7 respectively, but the rate is the same..

Orlando has a bank statement balance of $414.25 and $5.90 service charge. His check register shows $374.16 and he has two outstanding checks of $26.54 and $21.78. Orlando should:
Keep the adjusted checkbook balance.
Write the true balance in his checkbook.
Write the balance from the bank statement in his checkbook.
Answer:
$365.93
$368.26
Step-by-step explanation:
The true balance :
Statement balance - outstanding cheques
Statement balance = 414.25
Outstanding cheques = 26.54 and 21.76
414.25−26.54−21.78 = 365.93
Adjusted Chequebook balance
Chequebioknvakance will en adjyat d for service charge :
Chequebook balance - service charge
$374.16 - $5.90 = $368.26
Yuki concluded:
"It's not possible to map AABC onto AFED using a sequence of rigid transformations, so the triangles
are not congruent."
What error did Yuki make in her conclusion?
Answer:
One more transformation — a rotation — would map △ABC onto △FED So the triangles are congruent.

Don has an album that holds 900 coins . Each page of the album holds 9 coins . If 78% of the album is empty, how many pages are filled with ?
Answer: 22% of the pages are filled up
Step-by-step explanation: 900/9= 100 78% of 100 is 78
22+78=100 therefore reaching 100 percent. since 78% is empty that means 22% is being used.

Write the quadratic equation where the roots are -1/3 and 5
Answer:
f(x) = 3x² - 14x - 5
Step-by-step explanation:
multiply the factors: (x + 1/3)(x - 5)
x² - 5x + 1/3x - 5/3
x² -14/3x - 5/3
multiply by 3 to eliminate fractions:
3x² - 14x - 5

Answer:
Y=-2
Step-by-step explanation:
Hope that helps you
Answer:
y=-2
Step-by-step explanation:
first, you have to leave y alone so you have to add 2 on both sides to delete -2
y-2+2=-4+2
now -2+2=0 so that's gone and -4+2 is -2
Now you have the answer UvU
y=-2
is this a corresponding angle, alternate exterior angle, vertical angle, a supplementary angle, or a linear pair?
Answer:
Vertical angles
Step-by-step explanation:
∠[tex]5[/tex] and ∠[tex]7[/tex] are formed by the same lines and are "opposite" to each other, so they are vertical angles by definition. Hope this helps!

A tent has the shape of a triangular prism. Its volume is 25 m cube.
Find one possible whole-number dimension of the prism.
Calculate the surface area of the prism.
Answer:
Step-by-step explanation:
length=1 m
base of triangle=10 m
height=5m
volume= 1/2×10×5×1=25 m cube.
slant height l=√(5²+5²)=√50=5√2
slant surface area=2[5√2×1]=10√2
area of front and back=2×1/2(10×5)=50
total surface area=50+10√2≈50+14.14≈64.14 m²

How many terms of the AP -10,-7,-4,-1,.............must be added to get the sum -104?
pls do this fasttttttstttt
Answer:
The value of n is complex
Step-by-step explanation:
The sequence is an arithmetic sequence
Given
First term a = -10
common diff d = -7-(-10) = -4-(-7) = 3
Sn = -104
get the number of terms n using the formula
Sn = n/2[2a+(n-1)d]
-104 = n/2[2(-10)+(n-1)(3)]
-104 = n/2[-20+3n-3]
-208 = n{3n-23}
-208 = 3n²-23n
3n²-23n+208 = 0
Factorize
n = 23±√23²+4(3)(208)/2(3)
n = 23±√529-2496/6
Since the value of n is a complex number, hence the value of n does not exist
