Answer:
im pretty sure that the answer your looking for is 90
Step-by-step explanation:
Answer:
90
Step-by-step explanation:
STEP 1 27 = 30% × Y
STEP 2 27 = 30/100 × Y
Multiplying both sides by 100 and dividing both sides of the equation by 30 we will arrive at:
STEP 3 Y = 27 × 100/30
STEP 4 Y = 27 × 100 ÷ 30
STEP 5 Y = 90
Finally, we have found the value of Y which is 90 and that is our answer.

(8x+6) (10x+9y) 73° 110°
Answer:{x,y}={-1,-4}
Step-by-step explanation:
[2] 8x = 4y + 8
[2] x = y/2 + 1
// Plug this in for variable x in equation [1]
[1] 10•(y /2+1) - 9y = 26
[1] - 4y = 16
// Solve equation [1] for the variable y
[1] 4y = - 16
[1] y = - 4
// By now we know this much :
x = y/2+1
y = -4
// Use the y value to solve for x
x = (/2)(-4)+1 = -1

Last week the price of apples at a grocery store was $1.60 per pound this week apples at the same grocery store are on sale at 10% discount what is the total price of four and
1/2 pounds of apples this week at the grocery store
Answer:
0.72
Step-by-step explanation:
first you take 1.60 and find 10 percent of it once you find that you times it by 4.5.
Answer:
$6.48
Step-by-step explanation:
10 = 0.16
1.60-0.16=1.44
1.44x4=5.76
1.44/2=0.72
5.76+0.72=6.48
50 pencils cost €7 . how much would 5 pencils cost
Answer:
5 pencils will cost €0.7
Step-by-step explanation:
We can set up a proportion to solve. We will have the cost on the top and the number of pencils on the bottom. I will have 50 pencils on the left, and 5 pencils on the right.
[tex]\frac{7}{50}=\frac{x}{5}[/tex]
Now we will cross multiply.
7 * 5 = 50 * x
35 = 50x
Divide both sides of the equation by 50.
0.7 = x
x = 0.7
5 pencils will cost €0.7

Find the inverse of the rational function
F(x)= 2x/x+3, x≠-3
as you already know, to get the inverse of any expression we start off by doing a quick switcheroo on the variables and then solving for "y", let's do so.
[tex]\stackrel{f(x)}{y}~~ = ~~\cfrac{2x}{x+3}\implies \stackrel{\textit{quick switcheroo}}{x~~ = ~~\cfrac{2y}{y+3}}\implies xy+3x=2y\implies xy-2y+3x=0 \\\\\\ xy-2y=-3x\implies \stackrel{\textit{common factoring}}{y(x-2)=-3x}\implies y=\cfrac{-3x}{x-2}\implies \stackrel{f^{-1}(x)}{y}=\cfrac{3x}{2-x}[/tex]
Jessica needs at least 60 units of vitamin A, 40 units of vitamin B, and 140 units of vitamin C each week. She can choose between Costless brand or Savemore brand vitamins. A Costless vitamin costs 5 cents and contains 3 units of vitamin A, 1 unit of vitamin B, and 2 units of vitamin C. A Savemore vitamin costs 7 cents and contains 1 unit of A, 1 of B, and 5 of C. Determine the minimum cost for Jessica to purchase all the vitamins she needs.
Answer:
$2.40
Step-by-step explanation:
Let x be the number of Costless vitamins and let y be the number of Savemore vitamins. Since we are trying to minimize cost, our objective function represents the cost of buying both Costless and Savemore vitamins. This function is defined by
C(x,y)=0.05x+0.07y
The first constraint is that Jessica needs 60 units of vitamin A and we know that Costless vitamins have 3 units of vitamin A and the Savemore vitamin has 1 unit of Vitamin A. This translates into the following inequality.
3x+y≥60
The second constraint is that Jessica needs at least 40 units of vitamin B and we know that Costless and Savemore vitamins each have 1 unit of vitamin B. This translates into the following inequality.
x+y≥40
The third constraint is that Jessica needs at least 140 units of vitamin C and we know that the Costless vitamin has 2 units of vitamin C and Savemore vitamins has 5 units of vitamin C. This translates into the following inequality.
2x+5y≥140
The fact that x and y must be positive numbers is represented by the following two constraints:
x≥0,y≥0
Using all of this information, our problem is as follows.
Minimize: C(x,y)=0.05x+0.07y
Subject to: 3x+y≥60
x+y≥40
2x+5y≥140
x≥0
y≥0
The corner points are:
(0,60),(70,0),(10,30),(20,20)
To minimize cost, we will substitute these points in the objective function to see which point gives us the lowest number. The results are listed in the table below.
The point (20,20) gives lowest cost: $2.40 .

Solve the inequality: −2x > −6
Answer:
[x < 3]
Step-by-step explanation:
-2x > -6
To solve inequalities, you need to get x alone.
Simply, divide both sides by -2,
-2x > -6
x > 3
When we divide a number by a negative during solving, we have to flip the inequality sign, therefore:
[x < 3]
Answer:
x<3
Step-by-step explanation:
Change signs on both sides of an inequality:
2x<6
x<3
A square patio has a perimeter of (16x + 12) feet. What is the length of the patio?
Solution:
Note that:
Squares always have equal sides and angles.Perimeter of square patio: (16x + 12) ft.Factorize the perimeter.
16x + 12=> 4(4x + 3) ft.Find the length of the patio.
4(4x + 3)/4=> 4x + 3 ft.The length of the square patio is 4x + 3 ft.
Find the surface area of rectangular prism
Edit: I misread the question
Answer:
392 inches sq.
Step-by-step explanation:
To find the surface area, find the area of all side first and then add them together at the end. Area = (length)(width)
The problem gives you the length, width, and height of the prism which is all you need to find the dimensions of each side.
The area of the side facing us would be (9)(14)=126 in. sq. There's two of these sides, one is just hidden. So we would do (126)(2)=252 in sq to get the total area of these two sides.
Moving on to the side on the side, we would do (3)(9)=27, then (27)(2)= 54 in sq.
The side on top would be (14)(3)=42 and then (42)(2)= 84 in sq.
Now, for the final surface area we would just add these all together! 252+54+84=392, so the surface area would be 392 in sq.

Which function has a vertex at (2, -9)?
O f(x) = -(x - 3)2
O f(x) = (x + 8)2
O f(x) = (x - 5)(x + 1)
f(x) = -(x - 1)(x - 5)
The function [tex]f(x)=\left(x-5\right)\left(x+1\right)[/tex] has a vertex at (2, -9).
Quadratic functionThe quadratic function can be represented by a quadratic equation in the Standard form: [tex]ax^2+bx+c[/tex] where: a, b and c are your respective coefficients. In the quadratic function the coefficient "a" must be different than zero ([tex]a\neq 0[/tex]) and the degree of the function must be equal to 2.
For solving this question, you should find the vertex of quadratic equation (h,k). Where, [tex]h=-\frac{b}{2a}[/tex] . On the other hand, the value of the k-coordinate will be found when you replace the value of h in the equation of your question.
1. [tex]f(x)=-(x-3)^2[/tex]
Write this equation in Standard form:
[tex]f(x)=-(x^2-6x+9)\\ \\ f(x)=-x^2+6x-9[/tex]
Find h, using the formula [tex]h=-\frac{b}{2a}[/tex]
[tex]h=-\frac{b}{2a} =-\frac{6}{2*(-1)} =-\frac{6}{-2}=-(-3)=3[/tex]
Find k, replacing x for the value of h
[tex]-x^2+6x-9\\ \\ -(3)^2+6*3-9=-9+18-9=-18+18=0[/tex]

Find h, using the formula [tex]h=-\frac{b}{2a}[/tex]
[tex]h=-\frac{b}{2a} =-\frac{16}{2*1} =-\frac{16}{2}=-8[/tex]
Find k, replacing x for the value of h
[tex]x^2+16x+64\\ \\ (-8)^2+16*(-8)+64=64-128+64=128-128=0[/tex]
The vertex of quadratic equation is (-8,0). Incorrect Option.
3. [tex]f(x)=\left(x-5\right)\left(x+1\right)[/tex]
Write this equation in Standard form:
[tex]f(x)=(x^2+x-5x-5)\\ \\ f(x)=(x^2-4x-5)[/tex]
Find h, using the formula [tex]h=-\frac{b}{2a}[/tex]
[tex]h=-\frac{b}{2a} =-\frac{-4}{2*1} =-\frac{-4}{2}=-(-2)=2[/tex]
Find k, replacing x for the value of h
[tex]x^2-4x-5\\ \\ 2^2-4*2-5=4-8-5=-4-5=-9[/tex]
The vertex of quadratic equation is (2,-9). Correct Option.
4. [tex]f(x)=-\left(x-1\right)\left(x-5\right)[/tex]

Ann found an orange caterpillar and a green caterpillar in her backyard. The green caterpillar was 3/4 of an inch long and the orange caterpillar was 2/3 of an inch long. How much longer was the green caterpillar than the orange caterpillar? *
Answer:
[tex]\huge\boxed{\sf \frac{1}{12} \ in.}[/tex]
Step-by-step explanation:
Length of green caterpillar = 3/4 in.
Length of orange caterpillar = 2/3 in.
To find how much longer was the green caterpillar than the orange one, we will subtract the length of orange caterpillar from the green one.Solution:
[tex]\displaystyle = \frac{3}{4} - \frac{2}{3} \\\\LCM = 4 \times \ 3 = 12\\\\= \frac{(3 \times 3 ) - (2 \times 4)}{12} \\\\= \frac{9-8}{12} \\\\= \frac{1}{12} \ in.\\\\\rule[225]{225}{2}[/tex]
The band will play for 60 minutes. If the members want to play 5 songs of equal
length, how many seconds will each song have to be?
Answer:
12 minutes per each song.
Step-by-step explanation:
If they want to play 5 songs in a duration of 60 minutes, we would have to divide the total amount of minutes by how many songs they have to play.
Total Duration / Total Songs = Duration Per Song
60 / 5 = 12
Answer: Each song lasts 720 seconds, or 12 minutes each song.
Step-by-step explanation:
60 times 60 = 3600 sec.
3600 sec. divided by 5 equals 720
Each song lasts 720 seconds, or 12 minutes each song.
What is m<4 if m<5 = (2x) and m<4 = (x + 9)º?
Please
m∠4= 2x°
m∠5 = (x+9)°
case one: If both lie on the same plane then,
m∠4+ m∠5 = 180°
2x+x +9° = 180°
3x+9° = 180°
3x=171°
x= 171°/3
x= 57°
so,
m∠4 = 57° x 2° = 114°
m∠5= 57°+9° =66°
case two : If the angles are on opposite side of each other then,
m∠4=m∠5
2x= x+9°
2x-x=9°
x=9°
so,
m∠4m= 2x9 = 18°
∠5= 9+9= 18°
1.) m∠4 = 2x°
[tex]→m∠4+ m∠5 = 180°[/tex]
[tex]→2x+x +9° = 180°[/tex]
[tex]→3x+9° = 180°[/tex]
[tex]→3x=171°[/tex]
[tex]→x= \frac{171°}{3}[/tex]
[tex]→x= 57°[/tex]
So,
[tex]m∠4 = 57° × 2° = 114°[/tex]
[tex]m∠5= 57°+9° =66°[/tex]
2.) m∠5 = (x+9)°
[tex]→m∠4=m∠5[/tex]
[tex]→2x= x+9°[/tex]
[tex]→2x-x=9°[/tex]
[tex]→x=9°[/tex]
So,
[tex]m∠4m= 2×9 = 18°[/tex]
[tex]∠5= 9+9= 18°[/tex]
