Line AB on Circle A measures 7 cm. What is Circle A's circumference?
Answer:
Step-by-step explanation:
The circumference for a circle is found in the formula
[tex]C=\pi d[/tex]
so if the diamteter is 7, then the circumference is
[tex]7\pi[/tex] or if you are told to round to the nearest hundredth or thousandth, multiply pi in as 3.1415 to get that the circumference is 21.9905 cm

The number of students that earn straight A's decreases by half
each year. Currently there are 20 students who have all A's. Write
an equation to represent this scenario.
Step-by-step explanation:
20 ÷ 2 = S
S represents the students that have straight A's the next year. You would simply divide the current number of students by 2 and it will give you half the student number you had before. And those are the students who still are getting straight A's.

Lupita bought 7 pounds of pretzels at a local wholesaler for $16.80. Her friend Charles bought 5 pounds of pretzels at the supermarket for $12.75. Charles thinks he got the better deal because $12.75 is less than $16.80. 8a. Is Charles's reasoning correct? Explain why or why not.
Answer:
Charly has the better buy
Step-by-step explanation:
The unit cost is
=16.8/7
=$2.4
Her friend Charles bought 5 pounds of pretzels at the supermarket for $12.75
Unit cost
=12.75/5
=$2.55
Charly got the best deal because the unit cost per item is less than that of the friend

Suzanne bought 50 apples at the orchard. She bought 4 times as many red apples as green apples. How many more red apples than green apples did Suzanne buy?
Step-by-step explanation:
Let x be the number of Green apples bought.
Then 4x is the number of Red apples bought.
We have x + 4x = 50, so x = 10.
Since there are 10 green and 40 red apples, 40 - 10 = 30 more red apples than green apples.

4. Solve each equation for x. (8 points: 2 points each)
a.) 3x-12y=27
b.) 6x-7y=-2
c.) 4x-k=17
d.) kx+c=9
Answer:
a. x = 9 + 4y
b. x = (7y-2)/6
c. x = (17 + k)/4
d. x = (9-c)/k
Step-by-step explanation:
In each of the equations, we want to make x the formula subject
a) 3x-12y = 27
3x = 27 + 12y
3x = 3(9 + 4y)
x = 9 + 4y
b) 6x-7y = -2
6x = 7y-2
x = (7y-2)/6
c) 4x - k = 17
4x = 17 + k
x = (17 + k)/4
d) kx + c = 9
kx = 9-c
x = (9-c)/k
Rewrite the following equation in slope-intercept form. y - 8 = -8(x + 2)
Step-by-step explanation:
y - 8 = -8(x + 2)
y - 8 = -8x - 16
y = -8x - 8
The slope-intercept form is y = -8x - 8.
Answer:
y = -8x - 8
Step-by-step explanation:
First distribute the -8 into the parentheses
next get the the y by itself
add 8 to both sides and you get
y = -8x - 8

What is the volume of an object with the height of 2cm, a width of 4cm, a mass of 20g, and a length of 5cm?
Answer:
Step-by-step explanation:
.d
The volume of the object is 40cm^3
Let the object in question be a box. The formula for calculating the volume of a box is expressed as:
V = lwhGiven the following paraameters:
length = 5cmwidth = 4cmHeight = 2cmGet the volume of the shape.
V = 5cm * 4cm * 2cm
V = 40cm^3
Hence the volume of the object is 40cm^3

Peter leaves work and drives 10miles due south he then heads east for 11 miles to reach his home how far is Peter home from where he works round answer to nearest tenths place
Answer:
14.9 miles
Step-by-step explanation:
In the image below, the side of the triangle a, represents; "Peter leaves work and drives 10miles due south".
The side of the triangle b represents; "he then heads east for 11 miles to reach his home"
The distance between his work and home is represented by side c of the triangle.
This is a tight angle triangle, hence pythagoras theorem would be applied in solving it.
This theorem states that the square of the hypotenuse of a right angle triangle is equal to the sum of the squares of the other two sides;
This means we have;
c² = a² + b²
c² = 10² + 11²
c = √(100+121)
c = 14.87
Rounding off to the nearest tenths = 14.9
