Answer:
4 pt = 8 cups
28 qt = 7 gallons
Step-by-step explanation:
We know, from your chart, that 1 p = 2 c
4 p is four times 1 p
so, to scale up 1 pint to 4 pints, we multiply by 4
to figure out what the corresponding number of cups would be, we also have to multiply that value by 4
if 1 p = 2 c
then 4 p = 8 c
(1 x 4) (2 x 4)
8 cups
--------
If we have 28 quarts, and we know that 4 quarts is 1 gallon, we can divide 28 / 4 to find how many gallons are in 28 quarts (or, how many gallons can be made of 28 quarts)
28 / 4 = 7
7 gallons

Answer:
-7/8
Step-by-step explanation:
Quadratic formula is ax^2 + bx + c
In this case, x = -b/2a, which is -7/(2(4)) = -7/8
Answer:
x = - [tex]\frac{7}{8}[/tex]
Step-by-step explanation:
given a quadratic in standard form
f(x) = ax² + bx + c (a ≠ 0 )
then the equation of the axis of symmetry is
x = - [tex]\frac{b}{2a}[/tex]
f(x) = 4x² + 7x + 6 ← is in standard form
with a = 4 and b = 7
then equation of axis of symmetry is

Answer:
y=2x-5
explanation
m is gradient so rise over run and b is the y intercept which is -5
Answer: y = 2x - 5
Step-by-step explanation:
Method I:
▪︎ Slope: m = (y2 - y1) / (x2 - x1)
▪︎ b is where the graph crosses the y-axis
▪︎ Points: (1, -3), (2, -1)
▪︎ m = (-1 - (-3)) / (2 - 1) = (3 - 1) / (1) = 2
▪︎ b = -5
▪︎ => y = 2x - 5
Method II:
▪︎ y = mx + b
▪︎ Points: (1, -3), (2, -1)
▪︎ System of equations:
-3 = m*1 + b,
-1 = m*2 + b
-3 = m + b,
-1 = 2m + b
m = -b - 3,
-1 = 2(-b - 3) + b
m = -b - 3,
-1 = -2b - 6 + b
m = -b - 3,
-1 + 6 = -2b + b
m = -b - 3,
5 = -b
m = -(-5) - 3,
b = -5
m = 2,
b = -5
▪︎ => y = 2x - 5

Answers
Using proportions, it is found that 96,734 more obese people were there in evansville than in boulder.
What is a proportion?A proportion is a fraction of a total amount, and the measures are related using a rule of three.
For Evansville, the proportion of obese people is given by:
189/(311+189) = 189/500.
Hence, out of 358,676 people:
oE = 189/500 x 358676 = 135580.
For Boulder, the proportion is given by:
16/(16 + 109) = 16/125
Hence, out of 303,482 people:
oB = 16/125 x 303482 = 38846.
Hence the difference is given by:
135580 - 38846 = 96734

Answers
The number of the blue cubes is 35 and the number of the red cubes is 20.
What is the ratio?The ratio is defined as the representation of the one number with respect to the other number. or one number is how many times the other number.
Given that:-
In a bag, there are red and blue cubes in the ratio of 4: 7I add 10 more red cubes to the bag. Now there are red and blue cubes in the ratio of 6: 7The number of the blue cubes are calculated as:-
The two equations will be formed by the given data in the question.
[tex]\dfrac{r}{b}=\dfrac{4}{7}[/tex]
7r = 4b
[tex]\dfrac{r+10}{b}=\dfrac{6}{7}[/tex]
7r + 70 = 6b
Solving the above equation we will get the value of b.
4b + 70 = 6b
6b - 4b = 70
2b = 70
b = 35
7r = 4b
7r = 4 x 35
r = 20
Therefore the number of the blue cubes is 35 and the number of the red cubes is 20.

Step-by-step explanation:
First, get the area of the rectangle then subtract the triangle, the result will be the shaded area:
area rec = 18 * 11
area rec = 198 cm²
small side of tri = 11 - 5
small side of tri = 6 cm
area tri = (height * width) / 2
area tri = (6 * 18) / 2

Quadrilateral abcd has the vertices a(-6,4) , b(-4,5) , c(-3,3) , d(-5,1) . determine if quadrilateral abcd is a rhombus
Answers
Answer:
No
Step-by-step explanation:
The defining property of a rhombus is that it has equal side lengths.
=============================================================
Finding all side lengths :
AB
⇒ √(-4 + 6)² + (5 - 4)²
⇒ √2² + 1²
⇒ √5 units
BC
⇒ √(-3 + 4)² + (3 - 5)²
⇒ √1² + (-2)²
⇒ √5 units
CD
⇒ √(-5 + 3)² + (1 - 3)²
⇒ √(-2)² + (-2)²
⇒ √8 units
DA
⇒ √(-6 + 5)² + (4 - 1)²
⇒ √(-1)² + 3²
⇒ √10 units
As all side lengths of the quadrilateral are not equal, ABCD is not a rhombus.

Answer:
Option C is correct. The system of linear equation -5.9x - 3.7y = -2.1 and 5.9x +3.7y = 2.1 have infinitely many solutions.
What is system of linear equation?
The system of linear equations is "a set of two or more linear equations or variables is called system of linear equation".
What is infinitely many solutions?
An equation has infinitely many solutions only if "the two lines are coincident and having the same y-intercept".
According to the question,
The system of linear equation,
-5.9 x - 3.7y = -2.1 → (1)
5.9 x + 3.7y = 2.1 → (2)
The equation (1) is same as the equation (2) only the difference equation (1) is multiplied by (-1). Both equation give the same line. To check if above equations have same y-intercept, the equation can be written in slope intercept form y = m x +c where 'm' is the slope of the line, 'c' is the 'y-intercept'.
y = - (5.9/3.7) x + 2.1 [From equation (1)]
y = -(5.9/3.7) x + 2.1 [From equation (2)]
The both equation have same y-intercept. Therefore, the system of linear equations have infinitely many solution.
Hence, the system of linear equation -5.9x - 3.7y = -2.1 and 5.9x +3.7y = 2.1 have infinitely many solutions.
