Answer:
4/81 = a
Step-by-step explanation:
The vertex form of a parabola is
y = a (x-h)^2 +k where (h,k) is the is the vertex
y = a (x- -5)^2 -2
y = a (x+5)^2 -2
Substituting the point into the equation
2 = a( 4+5)^2 -2
2 = a( 9)^2 -2
2 = a (81) -2
Add 2 to each side
4 = 81 a
Divide each side by 81
4/81 = a
Answer:
a=4/81

© The ratio of boys to girls in a class is 5:4. There are 36 students in the class. How many
students are girls?
Answer:
16
Step-by-step explanation:
[tex]no \: of \: girls = \frac{4}{5 + 4} \times 36 \\ \\ = \frac{4}{9} \times 36 \\ \\ = 4 \times 4 \\ \\ = 16[/tex]
Answer:
Step-by-step explanation:
let the ratio of boys and girls be 5x and 4x
According to question,
5x+4x = 36
or, 9x= 36
x=4
number of boys = 5x
= 5·4= 20
number of girls = 4x
= 4.4=16
therefore the total no of boys is 20 ans girls is 16

When 17 is divided by K ; where k is a positive integer less than 17 the remainder is 3 .What is the remainder when the sum of the beta possible values of Kivided by 17.
Answer:
The remainder is 4.
Step-by-step explanation:
Note: This question is not correctly stated. It is therefore correctly restated before answering the question as follows:
When 17 is divided by k; where k is a positive integer less than 17, the remainder is 3. What is the remainder when the sum of the possible values of k is divided by 17?
The explanation of the answer is now given as follows:
Since k < 17, it implies that the possible values of k must be from between 1 and 16 inclusive.
Between 1 and 16, only 7 or 14 will give a remainder of 3 when either of them is used to divide 17. Therefore, 7 and 14 are the possible values of k.
Therefore, we have:
Sum of the possible values of k = 7 + 14 = 21
Also, we have:
Sum of the possible values of k divided by 17 = 21 / 17 = 1 with a remainder of 4.
Therefore, the remainder is 4 when the sum of the possible values of k is divided by 17.

A company loses $5,400 as the result of a manufacturing defect. Each of the 8 owners have agreed to contribute an equal amount, x, to help pay for the losses.
Part A
Which expression shows the total loss after the owners contribute some money?
Answer:
x=$5400:8
$5400:8x = total loss after the owners contribution
The expression shows the total loss after the owners contribute some money is 8x = 5400
Equation
An equation is an expression used to show the relationship between two or more numbers and variables.
Let x represent the amount contributed by each owner as loss.
Since there are 8 owners sharing a loss of $5400, hence:
8x = 5400
x = 675
The expression shows the total loss after the owners contribute some money is 8x = 5400

Find the nth term of this quadratic sequence
4,9, 16, 25, 36,
Answer:
[tex]a_{n}[/tex] = (n + 1)²
Step-by-step explanation:
The terms are square numbers with each term shifted to the right by 1
That is 1, 4, 9, 16, 25, 36, .....
Thus to obtain 4 in the first position, then
n = 1 → (1 + 1)² = 2² = 4
To obtain any term add 1 to its position in the sequence, that is
[tex]a_{n}[/tex] = (n + 1)²

I have a half-full bottle of water and it has more than 8 ounces in it. What would be the expression
Answer:
The equivalent expression is [tex]\frac{1}{2}\cdot V_{max} > 8\,oz[/tex].
Step-by-step explanation:
The best approach consists in translating the sentence given in the question into mathematical terms until an expression is complete:
(i) I have a half-full bottle of water
Translation: I use a bottle with a maximum volume capacity [tex]V_{max}[/tex], measured in ounces, a half of it is full of water:
[tex]\frac{1}{2}\cdot V_{max}[/tex]
(ii) And it has more than 8 ounces in it
Translation: The volume occupied by the water is greater than 8 ounces. Hence, we get the following inequation:
[tex]\frac{1}{2}\cdot V_{max} > 8\,oz[/tex]
If y = 80 when x = 32, find x when y = 100.

and 100= x so the answer will be 32*100 divided by 80 is equal to 40 I guess it's 40 the value of x is 40 in my guess
There are 20 sweets in a box.
x of the sweets are red.
The rest of the sweets are yellow.
Tom takes at random a sweet from the box.
Write down an expression, in terms of x, for the probability that Tom takes a yellow sweet.
Answer:
[tex]probability \: of \: getting \: red \: sweets = \frac{x}{20} \\ probability \: of \: getting \: yellow \: sweets \: = \frac{(20 - x)}{20} [/tex]
The probability of getting red sweets is x/20 and the probability of getting yellow sweet is (20-x)/20.
What is a probability?Probability is about estimating or calculating how likely or 'probable' something is to happen.
Given that x is the number of red sweets.
The total number of sweets is 20.
The number of yellow sweets = 20 - x.
The probability of getting a red sweet is given by
P(x) = x/20
The probability of getting a yellow sweet is given by
P(20-x) = (20-x)/20
Hence, x/20 is the probability of getting a red sweet and (20-x)/20 is the probability of getting yellow sweet.

Factors of 2ab: 1, 2, a, and b
Factors of 8b: 1, 2, 4, 8, and b
GCF: (1) (1) (2) (2) (b) (b)
Which best describes the error in Tawanna’s solution?
Tawanna factored one or both pieces of the expression incorrectly.
Tawanna did not include each factor in the GCF.
Tawanna should have used each common factor once.
Tawanna included only one of the variables in her solution.
Mark this and return
Answer:
Tawanna should have used each common factor once.
Step-by-step explanation:
Tawanna is asked to find the GCF of each term in the expression 2 a b + 8 b.
Factors of 2ab: 1, 2, a, and b
Factors of 8b: 1, 2, 4, 8, and b
GCF: (1) (1) (2) (2) (b) (b)
GCF = Greatest common factor
She has calculated the GCF incorrectly as she should use each common factor once only. But she has taken all the common factors twice which is wrong.
Hence, the error in Tawanna’s solution is that "Tawanna should have used each common factor once.". Hence, the correct option is (c).
Answer:
C - Tawanna should have used each common factor once.

What time is it exactly 1,440,000 minutes after 10 pm
Answer:
The answer is 11 PM
Step-by-step explanation:
1,440,000 minutes is the same as 24,000 hours. Then, you add that to 10pm of that day and you get 11 pm. It is the same as multiplying 24 x 1000 hrs. it is like adding 1000 days to that since it is 24 hrs in one day. Hope this helped!!
Answer:
11:00 pm
Step-by-step explanation:
1,440,000 minutes, convert it into hours and you get 24,000 hours. Since 24 hours equal a day 24,000 is 1,000 days. Attach 10:00 pm since its exactly 1,000 days after and you get 11:00 pm.
