Answer:
[tex] \huge \boxed{c = 4 \sqrt{2} }[/tex]
Step-by-step explanation:
Since the triangle is a right angled triangle we can use Pythagoras theorem to find the missing side x
Using Pythagoras theorem we have
c² = a² + b²
where
c is the hypotenuse
So from the question we have
[tex] {c}^{2} = {4}^{2} + {4}^{2} \\ c = \sqrt{16 + 16} \\ c = \sqrt{32} \: \: \: \: \: \: \: \: \: \\ \\ \\ c = 4 \sqrt{2} \: \: \: \: \: \: \: \: [/tex]

At 6:00 am, there was 1 inch of snow on the ground. By 11 am, there were 4 inches of snow on the ground. What is the average rate of change?
If the snow continues to fall at the same rate, how much snow will be on the ground by 1:00 pm.
Answers
Answer:
0.6 inches per hours
5.2 inches on the ground by 1:00 pm
Step-by-step explanation:
Let x = number of hours after midnight
Let y = height of snow (in inches)
Information presented as ordered pairs (x, y):
(6, 1)
(11, 4)
[tex]\mathsf{rate \ of \ change=\dfrac{change \ in \ y}{change \ in \ x}=\dfrac{4-1}{11-6}=\dfrac35 \ inches \ per \ hour}[/tex]
Written as a linear equation:
[tex]y-1=\dfrac35(x-6)[/tex]
[tex]\implies y=\dfrac35x-\dfrac{13}{5}[/tex]
1:00 pm = 13 hours after midnight
Therefore, when x = 13:

A rock sample has a mass of 16 grams and a volume of 8 cubic centimeters. 'When the
rock is cut in half, what is the volume and density of each piece?
Answers
Answer:
Volume= 4 cm³
Density= 2 g/cm³
Step-by-step explanation:
We have the following data:
volume= V= 8 cm³
mass= m= 16 g
The density is the mass per volume of a substance, so the density of the rock is:
density= d= 16 g/8 cm³= 2 g/cm³
When we cut the rock in half, we have a half volume and a half mass:
V= 8 cm³/2= 4 cm³
m= 16 g/2= 8 g
But the density is not altered because it is an intrisic property - it does not change with the amount of subtance. Thus, the density of a half rock is:
d = m/V= 8 g/4 cm³= 2 g/cm³

What is the median of the following dataset? (1,5,6,3,4,5,6,8,9)
Answers
Answer:
The median would be the second 5
Therefore our answer would be 5
Step-by-step explanation:
The median is the value separating the higher half of a data sample, a population, or a probability distribution, from the lower half. In simple terms, it may be thought of as the "middle" value of a data set. For example, in the data set {1, 3, 3, 6, 7, 8, 9}, the median is 6, the fourth number in the sample. The median is a commonly used measure of the properties of a data set in statistics and probability theory

Answers
Answer:
Given that m∠ABC = m∠CBD, and m∠ABD = m∠ABC + m∠CBD BC bisects m∠ABD (Definition of angle bisector)
Step-by-step explanation:
The given information are;
m∠ABC = m∠CBD
To prove that Ray BC bisects m∠ABD
The description is therefore;
Three lines (AB, BC, and BD) that meet at a point
The content of Box A = m∠ABC = m∠CBD
The content of Box B = m∠ABC ≅ m∠CBD
The content of Box C = Ray BC bisects m∠ABD
Therefore, we have;
m∠ABD = m∠ABC + m∠CBD (Angle addition postulate)
m∠ABC = m∠CBD (Given)
∴ m∠ABC ≅ m∠CBD (Definition of congruent angles)
m∠ABC is adjacent to m∠CBD (Description of the angles)
Line BC is common to m∠ABC and m∠CBD (Description of the angles)
Therefore, given that m∠ABC = m∠CBD, and m∠ABD = m∠ABC + m∠CBD BC bisects m∠ABD (Definition of angle bisector).

Three positive integers a, b, and x form an O'Hara triple (a,b,x) if and only if √a+√b=x. For example, (1,4,3) is an O'Hara triple because √1+√4=3. If (36,25,x) is an O'Hara triple, determine the value of x.
Answers
Work Shown:
[tex]\sqrt{a} + \sqrt{b} = x\\\\\sqrt{36} + \sqrt{25} = x\\\\6+5 = x\\\\11 = x\\\\x = 11[/tex]
The required value in (36,25,x) is an O'Hara triple, of x is 11.
Three positive integers a, b, and x form an O'Hara triple (a,b,x) if and only if √a+√b=x. For example, (1,4,3) is an O'Hara triple because √1+√4=3. If (36,25,x) is an O'Hara triple, To determine the value of x.
In mathematics, it deals with numbers of operations according to the statements.
From example,
(1,4,3) is an O'Hara triple because √1+√4=3, in the example sum of the square roots of the first two numbers is equal to the third number. so the value of x in (36,25,x) can be determined in the same manner.
Following the example,
√36+√25=x
6 + 5 = x
x = 11
Thus, the required value in (36,25,x) is an O'Hara triple, of x is 11.

Determine the number and type of solutions of the quadratic
equation.

O one imaginary solution
O two real solutions
O one real solution
O two imaginary solutions
Answers
Step-by-step explanation:
the degree of a polynomial determines 1:1 the number of solutions.
a quadratic equation (degree 2) has 2 solutions.
the general solution is
x = (-b ± sqrt(b² - 4ac))/(2a)
in our case
a = -4
b = -4
c = -1
so,
x = (4 ± sqrt((-4)² - 4×-4×-1))/(2×-4)
when we look at the square root
16 - 16
we see that it is 0.
the square root of 0 is 0, and there is no difference between -0 and +0.
so, we get only one (real) solution : 4/-8 = -1/2
but : formally, there are still 2 solutions (as this is a quadratic equation). they are just identical.
so, I am not sure what your teacher wants to see in this case as answer.
my answer would be 2 real identical solutions.
The line shown represents the amount of money left on a gift card, y, after Mina buys lattes. After buying 2 lattes, she has $2 left. What is an equation of the line in point-slope form?
Answers
Answer:
[tex]y-2 = -3(x-2)[/tex]
Step-by-step explanation:
Find the diagram to the question attached.
The standard equation of a line in point-slope form is expressed as:
[tex]y-y_0 = m(x-x_0)[/tex] where:
m is the slope of the line
[tex](x_0, y_0)[/tex] is coordinate point on the line
First is to get the slope of the line.
[tex]m = \frac{y_2-y_1}{x_2-x_1}[/tex]
If after buying 2 lattes, she has $2 left, hence one of the coordinate of the line is (2, 2). We can get the other coordinates from the graph. From the graph, it can be seen that when x = 0, y = 8. Hence the other coordinates is (0, 8)
[tex]m = \frac{8-2}{0-2}\\m = \frac{6}{-2}\\m = -3[/tex]
Hence the slope is -3
Substitute m = -3 and the point (2, 2) into the formula to get the required equation (note that any of the points can be used)
[tex]y-y_0 = m(x-x_0)\\y-2 = -3(x-2)[/tex]
Hence the equation of the line in point-slope form is [tex]y-2 = -3(x-2)[/tex]

Step-by-step explanation:
- 8x + 2y = - 4 → (1)
- 7x + y = - 8 ( add 7x to both sides )
y = 7x - 8 → (2)
substitute y = 7x - 8 into (1)
- 8x + 2(7x - 8) = - 4 ← distribute parenthesis and simplify left side
- 8x + 14x - 16 = - 4
6x - 16 = - 4 ( add 16 to both sides )
6x = 12 ( divide both sides by 6 )
x = 2
substitute x ;= 2 into (2)
y = 7(2) - 8 = 14 - 8 = 6
