Answer:
4
Step-by-step explanation:
Let the numbers be 2x,5x and 7x respectively.
2x+5x+7x=28
14x=28
x=28/14=2
Therefore the numbers are 2(2)=4,5(2)=10 and 7(2)=14
The smallest number is 4

Eight students got a B for the final test.If the ratio of the students that got A to the students who got B is y:x how many students got a A?Write a formula to give the number of students who got A, if x or y is given
Answer:
Number of students who got grade A = [tex]\frac{8y}{x}[/tex]
Step-by-step explanation:
Number of students who got grade B = 8
Ratio of the students that got A to the students who got B = [tex]y:x[/tex]
That is
Number of students who got grade A : Number of students who got grade B =
[tex]y:x[/tex]
Number of students who got grade A : 8 = [tex]y:x[/tex]
Therefore,
Number of students who got grade A = [tex]\frac{8y}{x}[/tex]
f(x) = - 4x ^ 2 + 4x - 4 Find f(3)
Need help
Answer: f(3) = - 28
Step-by-step explanation:
f(x) = - 4x² + 4x - 4
f(3) = - 4(3)² + 4(3) - 4 [We are solve for f(3), where x is equal to 3, we plug 3 for the x]
f(3) = - 36 + 12 - 4
f(3) = - 24 - 4
f(3) = - 28

X-9 _< 18 - 2x
X+2x _< 18+9
3x _< 27
x _< 27/3
x _< 9
Answer:
A
Step-by-step explanation:
Given
x - 9 ≤ 2(9 - x) ← distribute parenthesis
x - 9 ≤ 18 - 2x ( add 2x to both sides )
3x - 9 ≤ 18 ( add 9 to both sides )
3x ≤ 27 ( divide both sides by 3 )
x ≤ 9 → A

What are the x-intercepts for x2 - 5x + 6 = 0? (hint: factor
first)
Answer:x-intercepts (0,2) ; (0,3)
Step-by-step explanation:
x^2 - 5x + 6 =0
(x-2)(x-3) = 0
[-2 and -3 was the factors of 6, which make them equal to -5 when them add].
x-2=0 x-3=0

Answer:
3.9x+0.8y
Step-by-step explanation:
4x−5.2y+6y+7.9x−8x
Combine −5.2y and 6y to get 0.8y.
4x+0.8y+7.9x−8x
Combine 4x and 7.9x to get 11.9x.
11.9x+0.8y−8x
Combine 11.9x and −8x to get 3.9x.
3.9x+0.8y
It can also be converted to fraction form:

Hey guys I need some help. Question in the image below
Answer:
15 students at school
Step-by-step explanation:
So there is 50 students in total
First subtract that much with how much students have the flu
1/10 = 5/50
So 5 students have the flu
That leaves 45 students
Then subtract that much with the amount of students that are remaining are on the field trip
45 divided by 3 = 15
so 2/3 = 30/45 (they can both be multiplied and divided by 15)
so 30 of the 45 students are on the field trip
45 - 30 = 15
That means there are 15 students left over at school

Three squares each have sides of length 6 units and overlap each other as shown below. The points where the sides cross are midpoints. Find the area of the gray figure in square units.
Answer:
90
Step-by-step explanation:
Partition the figure by extending the sides of the ``middle'' square as shown at the right. Each original square contains four $3 \times 3$ small squares. The shaded figure consists of ten $3 \times 3$ squares, so its area is $10 \times 9 = \boxed{90\text{ square
units}}$.
In this exercise we have to use the knowledge of areas to calculate the area of the square in gray, so we have that:
[tex]A=90[/tex]
First it is informed that one side of the square is 6, so every square has exactly:
[tex]l^2=6^2=36[/tex]
Adding that we have 3 squares with the same value of sides:
[tex]36*3=108[/tex]
However, there are areas that are being calculated twice in the central square, these areas are smaller squares that have side values equal to 3, so:
[tex]l^2=3^2=9\\9*2=18\\108-18=90[/tex]

Solve for x in the diagram below.
Answer:
x = 20
Step-by-step explanation:
The sum of the two angles is 90 degrees
x+3x+10 = 90
Combine like terms
4x+10 = 90
Subtract 10 from each side
4x+10-10 = 90-10
4x= 80
Divide each side by 4
4x/4 = 80/4
x = 20
Answer:
x = 20
Step-by-step explanation:
x and 3x + 10 form a right angle, then
x + 3x + 10 = 90
4x + 10 = 90 ( subtract 10 from both sides )
4x = 80 ( divide both sides by 4 )
x = 20

what is the measure of x? someone actually help im confused
Answer:
angle x = 28 degrees
Step-by-step explanation:
Because of vertical angles, angle IAK and angle BAC are equal, and angle GCJ and angle ACB are also equal due to vertical angles
Since KL is perpendicular to FG, angle ABC is 90 degrees
ABC is a right triangle and acute angles in a right triangle are equal to 90 degrees
This means that angle BAC + angle ACB = 90 degrees
angle BAC = 62 degrees and angle ACB = x degrees
62 + x = 90
x = 28 degrees

Given cot A = 63/16 and that angle A is in Quadrant , find the exact value of sin A in simplest radical form using a rational denominator.
Answer:
sin(A) = 16*Cos(A)/63
Step-by-step explanation:
You didn't state what quadrant it was in.
The sine of angle A is 16 / 65
What is the sine of an angle?In a right-angled triangle, the sine of an angle is equal to the ratio of the side opposite to the angle (also called perpendicular) and hypotenuse.
Give that, cot A = 63/16 and that angle A is in Quadrant, (refer to the figure attached)
Since, we know that, cotangent of an angle is ratio of adjacent side to opposite side.
Using Pythagoras theorem, we get,
63²+16² = 4255
√4225 = 65
Therefore, the hypotenuse = 65
sine of an angle = opposite side / hypotenuse
sinA = 16 / 65
Hence, the sine of angle A is 16 / 65

find two numbers that have the given product and the given sum 36,16
Answer:
-2 and 18 is the answer
Step-by-step explanation:
Answer:
It differs by 4
16 - 12 = 4
4 = 4
Their product is 192
(16) (12) = 192
192 = 192
Step-by-step explanation: The sum of two numbers is 60 and their product is 576. Find the numbers. Let x and y are the two consecutive integers
The sum of two numbers is 60
x + y = 60 ---- (1)
Product of two numbers = 576
xy = 576
y = 576/x ----- (2)
Now we apply the value of x in (1)
x + (576/x) = 60
(x2 + 576) / x = 60
x2 + 576 = 60x
x2 - 60x + 576 = 0
(x - 12) (x - 48) = 0
x - 12 = 0
x = 12
If x = 12
y = 576 / 12
y = 48
x - 48 = 0
x = 48
If x = 48
y = 576 / 48
y = 12
So the required integers are 18 and The sum of two numbers is 60
48 + 18 = 60
60 = 60
The product is 576
48 (18) = 576
576 = 57648.
Two positive numbers differ by 4 and their product is 192. Find the numbers.
Let x and y be two positive numbers
It differs by 4
x - y = 4
x = 4 + y --- (1)
Their product is 192
xy = 192
y = 192/x --- (2)
By applying the value of y in (1), we get
x = 4 + (192/x)
x = (4x + 192)/x
x2 = 4x + 192
x2 - 4 x - 192 = 0
(x - 16) (x + 12) = 0
x - 16 = 0
x = 16
x + 12 = 0
x = -12
If x = 16
Then,
y = 192/16
y = 12
Since it is positive number we have to choose 16 for x.
