Identify the vertex of the parabola plssss..!!!!!!

Answer:

13 ounces

Step-by-step explanation:

Since the package ended up costing $5.81, we subtract the starting cost of 6 ounces, which is $4.90.

We end up with $0.91. Since each additional ounce is $0.13, we divide 0.91 by 0.13.

This gives us seven, which is the amount of additional ounces. Since Mrs. Washington paid 4.90 for the first six ounces and then there were an additional 7 ounces, we add 6 plus 7.

The answer is 13 ounces. Hope this helps!

Step-by-step explanation:

No. of classmates who like salsa music = (56÷100)×75 = 42

No. of relatives who like salsa music = (80÷100)×60 =48

How many more relatives like salsa as compared to classmates = 48-42= 6

Answer:

56 times

Step-by-step explanation:

To find the probability of both spinners landing on red, we need to multiply the probability of the spinner A landing on red (0.5) by the probability of the spinner B landing on red (0.6):

P(redA and redB) = 0.5 * 0.6 = 0.3

Then, to find the probability of both landing on blue, we do the same:

P(blueA and blueB) = 0.5 * 0.4 = 0.2

Now, if the number of times that both spinners land on red is 84, to estimate the number of times that both land blue, we just need to multiply this number of times by the ratio of P(blueA and blueB) over P(redA and redB):

84 * 0.2 / 0.3 = 56 times

Answer:

p = 50°.

Step-by-step explanation:

To find the value of 'p', we will need to solve for the measure of the other angles of the triangle using the Supplementary Angles theorem.

Notice 140° at the top of the figure. This angle is supplementary to the top angle of the triangle. We can find this angle by:

180 - 140 = 40°.

Repeat this same step for the other angle.

180 - 90 = 90°.

Since the sum of all 3 sides = 180, we must subtract these from 180 to get the measure of 'p'.

180 - 90 - 40 = 50°.

Therefore, p = 50°.

X=5/6

The value of X is 5/6

hope this helps.

Answer:

x = [tex]\frac{5}{6}[/tex]

Step-by-step explanation:

→Add 6 to both sides:

12x - 6 =4

12x = 10

→Divide both sides by 12:

x = [tex]\frac{10}{12}[/tex]

→Simplify:

x = [tex]\frac{5}{6}[/tex]

Answer:

By adding 4 to both sides.

2= -4 +b

2= b -4

2+4= b-4 +4

6= b

Another way to look at it is to move all the constants to one side. Here we have the constant 2 on the left hand side, and on the right we have the constant -4 and the variable b.

To isolate b, we move the constant -4 to the left hand side. Moving a number to the other side of the equal sign changes the sign of the number. So, -4 becomes a +4 on the left hand side.

2 +4= b

6= b

Step-by-step explanation:

your missing angle is

102 + 12

=114

the sum of triangle is 180 degree

180 - 114

= 66

the missing angle is 66 degree

Answer:

66 Degrees

Step-by-step explanation:

All angles equal 180 degrees so we know that :

180-102-12 =66

so the angle that is missing is 66 degrees.

Answer:

Acute and isoselces

Step-by-step explanation:

Isoseles triangles have two sides of equal length. Acute triangles' angles are all less than 90°.

The best describes the triangle is the acute and isosceles.

We have given that the triangle

We have to describe the given triangle

An isosceles triangle is a triangle that has two sides of equal length. Sometimes it is specified as having exactly two sides of equal length, and sometimes as having at least two sides of equal length, the latter version thus including the equilateral triangle as a special case.

Isosceles triangles have two sides of equal length. Acute triangle angles are all less than 90°.

Step-by-step explanation:

One foot=12 inches, but the teacher eats half, so we are left with only six inches. then, divide the six inches with the number of students, which is 4. if you divide 12 and 1.5, you'll see that there are a total of 8 pieces, so one student gets 1 out of the 8

ap3x

Answer:

84.6%

Step-by-step explanation:

There ae 52 cards in a standard deck there are 4 aces and 4 kings in each deck

therefore

52-8 =44, 44 cards that are not kings or aces

therefore the probability is

44/52 = 0.846153846*100 = 84.615%

There the chances are 44/52 or 84.6%

Answer:

11/13 or 84.62%

Step-by-step explanation:

There are 52 cards in a standard deck. There are 4 aces and 4 kings, 8 total. Subtract 8 from 52 to find the amount of cards that are not aces or kings:

52 - 8 = 44

Therefore, the probability of choosing a card that is not an ace or a king is 44/52, which can be simplified to 11/13. This can also be expressed as a percentage: approximately 84.62%.

Answer:

Adult ticket = $8

Student ticket = $13

Step-by-step explanation:

Hi, to answer this we have to write a system of equations (sales equations)

6x + 12y =204 (first day)

5x +3y =79 (second day)

Where x is the price of each adult ticket and y is the price of each student ticket.

If we multiply the second equation by 4 , and subtract the first equation to the second equation:

20x +12y =316

-

6x + 12y =204

___________

14x = 112

Solving for x:

x =112/14  

x = 8  

Substituting x=8 on any equation:

5x +3y =79

5(8)+3y =79

40+3y =79

3y =79-40

3y = 39

y =39/3

y = 13

The value of f(x) = x² - 2x  at x=4 is 8.

The core concept of mathematics' calculus is functions. The unique varieties of relations are the functions. In mathematics, a function is represented as a rule that produces a distinct result for each input x. In mathematics, a function is indicated by a mapping or transformation

Given:

f(x) = x² - 2x

Replace the x with -4.

f(-4) =  x² - 2x

Next, Evaluate the power.

=  (-4)² - 2(4)

Now, Calculate the rest.

= 16 + 8

= 8

Hence, the value of f(-4) is 8.

Isabella can have 8 full glasses and 0.75(3/4) glasses from the 1.75-liter carton of apple juice.

Fraction number consists of two parts one is the top of the fraction number which is called the numerator and the second is the bottom of the fraction number which is called the denominator.

Isabella buys a 1.75-liter carton of apple juice.

To convert it to milliliter multiply it by 1000

1.75 liter in ml = 1.75×1000 = 1750 ml

Let's suppose the number of glasses she can have is x, so the value of x:

x = 1750/200 = 8.75 glasses.

Thus, Isabella can have 8 full glasses and 0.75(3/4) glasses from the 1.75-liter carton of apple juice.

Answer:

B. 333 in.2

Step-by-step explanation:

The area of the base is 81^2

lateral is 45 x 4 = 180^2  (9x5x4)

180^2 add the 72 pyramid = 252^2 + base of 81^2 = 333^2

Composite figueres i do like this as shown to you a few seconds ago.

The triangle shows us just the height

4 inches

We can see that height is smaller central isosceles height across the center base point.

We also can remember to use the length 9inches but divide by 2 and get each triangle area this way.

4 x 1/2 base = 4x 1/2 4.5 = 4 x 2.25 = 9^2 each right side triangle

9 x 8 = 72^2

we add the areas 72+ 81+lateral 180 = 333 inches^2
