Step-by-step explanation:
15/y = 20/10
Cross multiply
150=20y
y=15/2
The value of y will be;
⇒ y = 7.5
What is Multiplication?
To multiply means to add a number to itself a particular number of times. Multiplication can be viewed as a process of repeated addition.
Given that;
The expression is,
⇒ 15 / y = 20 / 10
Now,
Solve the expression for y by using reciprocal property as;
The expression is,
⇒ 15 / y = 20 / 10
Apply reciprocal property;
⇒ y / 15 = 10 / 20
⇒ y = 15 × 10/20
⇒ y = 15 × 1/2
⇒ y = 7.5
Thus, The value of y will be;
⇒ y = 7.5

y = -1/6(x -3)^2 +6y = -1/6(x +3)(x -9)y = -1/6x^2 +x +9/2Step-by-step explanation:
1) The point at (3, 6) is on the vertical line that is halfway between the zeros at x=-3 and x=9, so it represents the vertex of the function. That knowledge, with any of the other points, lets you write the vertex form of the equation.
y = a(x -3)^2 +6
Using the point (0, 4.5), we can find the value of 'a':
4.5 = a(0 -3)^2 +6
-1.5 = 9a
-1.5/9 = a = -1/6
So, the vertex form of the equation is ...
y = -1/6(x -3)^2 +6
A graph of this is shown in the attachment.
__
2) Now that we know the leading coefficient is -1/6, we can write the equation in "intercept form" (factored form) as ...
y = -1/6(x +3)(x -9)
In this form, each zero (p) gives rise to a factor (x-p).
The second attachment shows the graph of this.
__
3) We can also write the equation in standard form, by expanding the one in (2) above:
y = -1/6(x^2 -6x -27)
y = -1/6x^2 +x +9/2
The third attachment shows the graph of this.

A rectangle is four times as long as it is wide. The perimeter is 40 cm. Find the length of each side.
Answer:
W=4 l=16
Step-by-step explanation:
Let w = width
Let l = length
Since the length is 4 times the width, l=4w
Perimeter of rectangle = 2l + 2w
= 2(4w)+2w
=10w
The perimeter of the rectangle =40, so
40=10w and w=4
Plug w into the length equation : l=4w=4(4)=16
Roger has $5000 more invested at 7 1/4% then he has at 6%. If his total profit at the end of the year $659.30, how much has he invested at each rate?
Answer:
You have the number of nickels and the number of quarters both expressed in terms of the number of dimes. So let your variable be the number of dimes. Call this D. Then the number of nickels is 4D, and the number of quarters is D+6. The total value is
0.10(D) + 0.05(4D) + 0.25(D+6) = 4.25
Solve this for D, and use D to find 4D and D+6.

A plant nursery is having a sale. Potted begonias are marked down 27%, and tomato seedlings are marked down 35%. If you pay $6.57 each for two potted begonias and $2.60 each for three tomato seedlings, how much did you save?
a. $3.83
b. $5.31
c. $6.92
d. $9.06
Answer:
D) $9.06
correct on edge :)
The total amount of money saved from purchasing the plants at a marked down price is $9.06
How much was saved?The first step is to determine the original price of one potted begonias: $6.57 / (1 - 0.27) = $9
The first step is to determine the original price of one tomato seedling: $2.60 / ( 1 - 0.35) = $4
The amount saved on potted begonias = ($9 - 6.57) x 2 = $4.86
The amount saved on tomato seedlings = (4 - 2.60) x 3 = $4.20
Total amount = $9.06

PLease answer ASAP!!!
Answer:
-57
Step-by-step explanation:
Use BOMASB- brackets
O- of
M- multiplication
A- addition
S - subtraction
-3[1+2(4+5)]
first solve what is in the brackets
(4+5) = 9
place 9 in the brackets
-3[1+2(9)]
now multiply the 2 and 9
2*9 = 18
-3[1+18)]
1+ 18 = 19
now multiply the (-3) with 19
= -57
Answer:
-57
Step-by-step explanation:
To solve this problem, you need to use the acronym PEMDAS.
P = parenthesis (if there is any in the expression) or brackets
E = exponents (if there is any in the expression)
D/M = Divide or Multiply or both
A/S = Add or Subtract or both
In the problem, you need to simplify the parentheses ( ) inside the brackets first. For example: -3 [1 + 2(4 + 5)]. That will equal to -3 [1 + 2(9)]. Next, you can solve the brackets now. Since there is both a addition and multiplication problem inside these brackets, you must do the multiplying first. For example,
-3 [1 + 2(9)]. That equals to -3 [ 1 + 18}. Next, do the addition inside of the brackets and then multiply that answer to -3. For example, -3 [1 + 18}. That equals to -3 [19]. Do the multiplication by a calculator or by hand. if you are doing by hand, ignore the signs of the numbers until the very end.
If doing by hand, first you need to multiply 9 by the 3 to get 27. Keep the 7 and borrow a 2 on top of the ones places which is 1. Multiply the 1 by the 3 which gets 3 and add 2 to the 3 to get 5. You got the 2 from multiplying 9 by 3 which is 27. Since the 3 in this problem is negative, that will leave your answer with a negative number. Since a negative times a postive will always be negative. If the number of negatives is odd in the problem, then it will a negative answer. If the number of negatives is even, the answer will be positive. Same thing applies to division. You get -57 as your answer.

11. REINFORCE In the circle below, the distance CN equals 3x - 10 and the distance CK
equals x2 - 20. Find the distance CP.
Answer:
5 units
Step-by-step explanation:
Here, we want to find the distance CP
the distance from the center of the circle to the circumference is referred to as radius.
Hence CP is the radius of the circle
Also CN is another radius and also CK is another radius
Thus, mathematically; CN = CK
This means that;
x^2 -20 = 3x -10
x^2 -20 -3x + 10 = 0
x^2 -3x -10 = 0
x^2 -5x + 2x -10 = 0
x(x-5) + 2(x-5) = 0
(x-5)(x+2) = 0
x = 5 or -2
To get CP , we can substitute for x in any of the given expressions
Let’s use 3x-10
Using x = 5
3(5) -10 = 15-10 = 5
Using x = -2
3(-2) -10 = -6-10 = -16
But since length cannot be negative , 5 units is our answer
Suppose you launch a model rocket with an upward starting velocity of v ft/s. You can use the equation to find the rocket's altitude, h represents height in feet, t seconds after launch and represents initial height. Suppose the upward starting velocity is 315 ft/s and the initial height is 3 ft. When will the rocket hit the ground?
Answer:
The rocket will hit the ground at 64.2 seconds.
Step-by-step explanation:
The time at which the rocket will hit the ground can be calculated using the following equation:
[tex] Y_{f} = Y_{0} + V_{0}y*t - \frac{1}{2}gt^{2} [/tex]
Where:
[tex]Y_{f}[/tex]: is the final height = 0
[tex]Y_{0}[/tex]: is the initial height = 3 ft
[tex]V_{0}[/tex]: is the initial speed = 315 ft/s
t: is the time =?
g: is the gravity = 9.81 m/s²
[tex] 3 + 315*t - \frac{1}{2}9.81*t^{2} = 0 [/tex]
Solving the above quadratic equation for t, we have the following values:
t₁ = -0.0095 s
t₂ = 64.2 s
Taking the positive value, we have that the rocket will hit the ground at 64.2 seconds.
I hope it helps you!
