length of ribbon required to cover the edge of a circular cloth of radius 35 cm
Mrs. Womack wants to make 22 mini pizzas for her favorite math class party. She
has 18 cups of flour and each mini pizza takes 4 cup of flour. Does she have enough
flour? If not, how much more flour does she need? If so, how much flour will she
have left over?
Answer:
She can only make 4 whole mini pizzas and needs 70 more cups of flour and will not have any leftover after that.
Step-by-step explanation:
18/4= 4.5
22*4=88
88-18= 70
Answer:
No
Step-by-step explanation:
Mrs. Womack need 22 mini pizzas and each requires 4 cups and when you do the math 22 times 4 is 88, and she only has 18 cups so she would only have enough to make 4 full pizzas. So in total she needs 88 cups meaning she needs 70 more.
22x4=88
88-18=70
18÷4= 4.5
Answer:70 more cups are needed

The table shows the temperature (y) at different altitudes (x). This is a linear relationship. Use the equation y = −0.004x + 79 to determine the temperature at an altitude of 5,000 feet.
Altitude (ft), x 0 2,000 4,000 6,000 8,000 10,000 12,000
Temperature (°F), y 79 71 63 55 47 39 31
The temperature at an altitude of 5,000 feet is
°F.
Answer:
59 degrees
Step-by-step explanation:
you plug in 5000 as x and solve
Eliminate the parameter, t, in the parametric equations, x = 2cos(t) and y = 2sin(t).
A) 4 x2 + 4 y2 = 4
B) x2 + y2 = 2
C) 2 x2 + 2 y2 = 4
D) x2 + y2 = 4
Answer:
D: [tex]x^2+y^2 = 4[/tex]
Step-by-step explanation:
Square each one, and add them together. Then collect 4 from both.
[tex]x^2 = 4 cos^2t; y^2 = 4sin^2 t \\x^2 + y^2 = 4( cos^2t+sin^2t) \rightarrow x^2+y^2=4[/tex]
Katie brought a birthday treat to school. She has 40 pieces of candy to share equally with the students in her class. If there are n students in the class, which expression shows how many pieces of candy each student will get?
Answer:
Step-by-step explanation:
Pieces = 40/n
Pieces = the number of pieces each student will get
n = the number of students in the class.
n
n has an upper limit of 40. Each student will get exactly 1 piece of candy
Other values of n could be
1 2 4 8 5 10 20 40
Answer:
2 candie each because if there 20 and 40 candie it well be 2:)`

Kim's school is selling tickets to a play. On the first day of ticket sales the school sold 5 senior citizen tickets and 6 child tickets for a total of $148. The school took in $189 on the second day by selling 7 senior citizen tickets and 7 child tickets. Find the price of a senior citizen ticket andthe price of a child ticket.
Answer:
Child $13 and Adult $14
Step-by-Step
x=cost of child tix
y=cost of adult tix
first day: 5y+6x=148
2nd day: 7y+7x=189
series of equations so solve for one variable
7y=189-7x
y=27-x
then plug into other equation
5(27-x)+6x=148
135-5x+6x=148
x=148-135
x=13
then plug into y equation
y=27-13
y=14

9month to 3/2 year express the following in ratio
Answer:
1 : 2
Step-by-step explanation:
in ratios both numerator and denominator should be in same units/measurement
so 3/2 year = 3/2 * 12 months
= 3 * 6
= 18 months
ratio is 9 : 18
1 : 2

Need Help?
Read It
If x terminates in the fourth quadrant, then we know that sin(x) < 0 and cos(x) > 0. Given that sec(x) = 8, we immediately have
cos(x) = 1/sec(x) = 1/8
Recall the Pythagorean identity,
cos²(x) + sin²(x) = 1
Then it follows that
sin(x) = -√(1 - cos²(x)) = -3√7/8
Now recall the double angle identities,
sin(2x) = 2 sin(x) cos(x)
cos(2x) = cos²(x) - sin²(x)
Then
sin(2x) = 2 (-3√7/8) (1/8) = -6√7/64 = -3√7/32
cos(2x) = (1/8)² - (-3√7/8)² = -62/64 = -31/32
By definition of tangent,
tan(x) = sin(x)/cos(x)
Then
tan(2x) = sin(2x)/cos(2x) = (=3√7/32) / (-31/32) = 3√7/31

In a school of 600, a survey was conducted with 10% of the population. The survey was conducted to narrow the choices for the new mascot. What was the frequency of Bears, if the following was the result of the survey?
Bears=22
Panthers=15
Beavers=2
Jaguars=21 no virus file answers
Answer:
36.67%
Step-by-step explanation:
So if 600 kids in total and 10% participate, then we have 60 kids to work with. Panthers plus beavers plus jaguars = 2 + 15 + 21 = 38. 38 + 22 = the total 60 kids. 22 is 36.67% percent of 60 because that's what 22/60 equals.

What is the question?
Step-by-step explanation:
how do you find the vertex of a quadratic equation in standard form?
Answer:
Step-by-step explanation:
The standard form of a quadratic equation is ax² + bx + c, where a ≠ 0.
Given that the axis of symmetry occurs at x = h, then we can assume that the h coordinate of the vertex is the same as the x-coordinate in an ordered pair, (x, y).
In order to find the vertex, (h, k), use the following formula to solve for the value of h:
[tex]h = \frac{-b}{2a}[/tex].
Example:To demonstrate this concept, let's say that we're given the following quadratic equation: 2x² + 8x + 8, where a = 2, b = 8, and c = 8. Substitute the values of a and b into the given equation for solving the x-coordinate (h) of the vertex:
[tex]h = \frac{-b}{2a}[/tex]
[tex]h = \frac{-8}{2(2)} = \frac{-8}{4} = -2[/tex]
Therefore, h = -2.
Next, substitute the value of h = -2 into the given quadratic equation in order to solve for its corresponding y-coordinate (k ) of the vertex:
k = 2x² + 8x + 8
where: a = 2, b = 8, and c = 8
k = 2(-2)² + 8(-2) + 8
k = 2(4) - 16 + 8
k = 8 - 16 + 8
k = 0
Therefore, the vertex of the quadratic equation, 2x² + 8x + 8 is (-2, 0).
