Answer:
axis of symmerty = x coordinate of vertex = -b/2a
-6/2 = -3 = x
vertex = (-3,y)
-3^2 +6(-3)

Answer:
x ≈ 17.32, y = 20
Step-by-step explanation:
sin (30°) = 10/y
=> y = 10/sin (30°)
=> y = 20
x = [tex]\sqrt{20^{2} - 10^{2}}[/tex]
=> x ≈ 17.32

Our club has 10 members, and we need to appoint a president, a vice president, and a secretary. How many ways can we do this if: Each member can hold at most one office. Members can hole any number of offices
Answer: 720
Step-by-step explanation:
Given
A club has 10 members and needs one president, a vice president, and a secretary
There are 10 positions for president i.e. 10 ways to select a member for it
Similarly, there 9 persons left to choose a position for vice president
likewise 8 persons for secretary
Total no of ways to do it are
[tex]\Rightarrow 10\times 9\times 8\\\Rightarrow 720\ \text{ways}[/tex]

volume of triangular prism
Answer:
48 cm^2
Step-by-step explanation:
The area of one of the triangular ends is A = (1/2)(4 cm)(3 cm) = 6 cm^2.
Multiply this "base area" by 8 cm, the length of the prism. We get:
volume of triangular prism = (6 cm^2)(8 cm) = 48 cm^2
(2^3//4^2)^5 What is the equivelant expression?
Answer:
A
Step-by-step explanation:
This is the same as ((2^3)/(4^2))*((2^3)/(4^2))*((2^3)/(4^2))*((2^3)/(4^2))*((2^3)/(4^2)) which is equal to (2^(3+3+3+3+3)/4^(2+2+2+2+2)), so its (2^15/4^10)

All four-sided figures are parallelograms true or false
pls explain why
Answer:
True
Step-by-step explanation:
Squares are quadrilaterals with 4 congruent sides and 4 right angles, and they also have two sets of parallel sides. Parallelograms are quadrilaterals with two sets of parallel sides. Since squares must be quadrilaterals with two sets of parallel sides, then all squares are parallelograms.
A rectangle has all the properties of a parallelogram, plus the following: The diagonals are congruent.
Squares are quadrilaterals with 4 congruent sides and 4 right angles, and they also have two sets of parallel sides.
Parallelograms are quadrilaterals with two sets of parallel sides. Since squares must be quadrilaterals with two sets of parallel sides, then all squares are parallelograms. This is always true. (actually is true)
hi can someone pls pls plsss! Help with this, I have a test and it’s due on Tuesday so I have time but for now can you pls help because this is apart of the test/practice so it’d be rlly helpful thanks!<333 have a good day!
Answer:
16 square feet is left uncovered.
Explanation:
Essentially, you’re trying to find the difference between the area of the door and the area of the poster. The area formula for a basic rectangle is l • w (length times width.) We have both of those dimensions for the separate shapes, so you can go ahead & do that math separately (as shown in the attachment!) Then, you subtract the area of the poster from the area of the door, and you have your answer. As always, I hope this is accurate & helpful! Good luck on your test, friend. Best wishes <3

Explanation:
Multiply the fractions 9/10 and 2/5 to get
(9/10)*(2/5)
(9*2)/(10*5)
18/50
9/25
---------------------
Here's a visual way to see what's going on. Start by drawing a rectangle of any size or shape. Cut the rectangle vertically into 10 equal slices. Then shade 9 of those slices to represent the fraction 9/10, which is how far (in miles) Lewis walked. See the diagram below. Specifically, refer to figure 1.
The friend walked 2/5 of this shaded amount. Draw 4 horizontal lines to split each vertical bar into 5 equal pieces. So we'll be forming a grid of smaller rectangles. For any given column, you'll shade exactly 2 smaller rectangles out of the 5 total. Hence the 2/5. This is shown in yellow in figure 2. The yellow region is 2 units tall by 9 units across, so we have 2*9 = 18 yellow rectangles in all. This is out of 5*10 = 50 smaller rectangles overall.
That's how we get to the fraction 18/50 which reduces to 9/25 when you divide both parts by the GCF 2.

Answer:
150 ft²
Step-by-step explanation:
area for triangle A=bh/2
A= (10)(6)/2
A= 30 ft²
area for a rectangle A=bh
A= (10)(12)
A= 120 ft²
together
120 + 30 = 150 ft²

EL 5% DEL 20% DEL 60% DE LA MITAD DE UN NUEMRO ES 24 . HALLAR EL NUMERO es para hoy ayudenme por favor les dare coronita
Answer:
El número inicial es 8000.
Step-by-step explanation:
A continuación procedemos a convertir la oración en una expresión matemática:
El 5 % del 20 % del 60 % de la mitad de un número es 24. [tex]x[/tex] sea el número de la expresión:
[tex]\frac{1}{2}\times \frac{5}{100}\times \frac{20}{100}\times \frac{60}{100}\times x = 24[/tex]
[tex]\frac{6000}{2000000} \times x = 24[/tex]
[tex]\frac{6}{2000}\times x = 24[/tex]
[tex]\frac{3}{1000}\times x = 24[/tex]
[tex]x = 8000[/tex]

URGENT MARKING BRAINLIEST
Answer:
for the first questions: 36%
Step-by-step explanation:
To answer the first question: What percent of people chose Mexican food?
Number of people who choose mexican food: 27
Total number of people who took the survey: 24 + 27 + 9 + 15 = 75
So, 27 out of 75 people choose mexican food, or in other words 27/75. If you divide 27/75, you get the decimal 0.36. This decimal is the same thing as 36%.
The steps for the other three questions are the same.

The telephone company offers two types of service. With Plan A, you can make an unlimited number of local calls per month for $18.50. With Plan B, you pay $6.50 monthly, plus 10 cents for each min. Of calls after the first 40 min. At least how many min would you have to use the telephone each month to make Plan A the better option?
Answer:
This is telling me that plan B is the better choice
for a certain number of minutes, but after that,
plan A is better.
Let +n+ = number of minutes of calls
with plan B
-----------------------------------------
Set up an equation that makes the 2 plans equal
and then add 1 more minutes to +n+
-----------------------------------------
plan A = plan B
+18.5+=+6.5+%2B+.1%2A%28+n+-+40+%29+
Step-by-step explanation:
Answer:
Plan A is better if you talk at least 121 minutes per month
Step-by-step explanation:
1. Plan B is $6.50 plus 10 cents for each minute
2. Plan A is $18.50
3. For plan A to be better, one need to spend over $12 extra
4. Each minute cost 10 cents, so $12 would be 120 minutes of talk
5. Plan A is better if you talk at least 121 minutes
