Step-by-step explanation:
Given y varies inversely as x, and y = 5 when x = 9. *Write the inverse function
Answer:
y = 45/x
Step-by-step explanation:
Here, we want to write an inverse relationship
for an inverse relationship, the product of both variables will be equal to the constant term
Let us have the constant term as k
Thus, we have it that;
xy = k
9 * 5 = k
k = 45
So the inverse function is;
xy = 45
or y = 45/x
if y is a function of x, we can have it as;
f(x) = 45/x

1. Find the area of parallelogram ABCD.
Round to the nearest tenth.
A 55.4 m2
C 69.3 m2
B 60 m2
D 80 m2
2. The area of the parallelogram DEFG is 143 square units.
Find the height. Round to the nearest tenth if necessary.
Fll units
H 22 units
G 14.3 units
J 44 units
3. The base of a triangle is three times its height.
If the area of a triangle is 54 square inches, find its height.
A 18 in.
C3 in.
B 6 in.
DI in.
4. Find the area of quadrilateral PQRS.
F 34.1 units
G 65 units?
H 130 units?
J 360 units
Answer:
1: C =69.3 m2
2: F = ll units
3. C: 3 in.
4. G =65 units
Step-by-step explanation:
1: C =69.3 m2
We see from the figure that height of the parallelogram ABCD is not known and the base is 10 m
Taking the right angled triangle the height is given by
Sine theta= height/hypotenuse
height = hypotenuse* sine theta
= 8* sine 60
= 8* 0.866= 6.928
Area of parallelogram= base * height
= 10 * 6.928
= 69.28
=69.3 m²
2: F = ll units
We see from the figure that height of the parallelogram DEFG is not known and the base is 13 cm
Area of parallelogram= base * height
143 = 13 * height
Height = 143/13= 11 units
3. C: 3 in.
The area of the triangle = 1/2 * base * height
Let the height be x then the base is 3x
54= 1/2*x*3x
54= 3x²/2
27= 3x²
x²=27/3
x²= 9
x= 3
The height is 3 inches
4. G =65 units
Area of the quadrilateral = 1/2 *PR*QO + 1/2 *PR*OS
= 1/2*13*4+ 1/2*13*6
=26+ 39
= 65 units
These measurements are given in the diagram .

Mrs. James is making snow cone cups using a special-coated paper to sell at a school
fundraiser. The snow cone cups have a diameter of 4 inches across the widest part of the
snow cone and are 5 inches tall.
What value most closely represents the amount of coated paper in square inches that Mrs.
James will need to make 150 snow cone cups?
Answer:
6957 inches squared
Step-by-step explanation:
surface area of a cone = πr × (r + √[h² + r²])
h = height
r = radius = 4/2 = 2 inches
the diameter is the straight line that passes through the centre of a circle and touches the two edges of the circle.
A radius is half of the diameter
(3.14 x 2) x (2 + √5² + 2²) = 6.28 x 7.39 = 46.38 inches squared
the amount of coated paper needed for 1 cup is 46.38 inches squared
Amount needed for 150 cups = 46.38 x 150 = 6957

In order for Tim to simplify the expression below, what step will he need to use for each variable's exponent? 6 x y^2 z^4 2 x^2 y^5 z A Divide the exponents B Multiply the exponents C Add the exponents D Subtract the exponents
Answer:
C. Add the exponents
Step-by-step explanation:
The given expression is presented as follows;
6·x·y²·z⁴·2·x²·y⁵·z
The expression can be rearranged by according to like terms as follows;
6·2·x·x²·y²·y⁵·z⁴·z = 3·2·2·x·x²·y²·y⁵·z⁴·z
By the law of indices, we add the exponents of the like terms to simplify the expression as follows;
3·2·2·x·x²·y²·y⁵·z⁴·z = 3·2⁽¹⁺¹⁾·x⁽²⁺¹⁾·y⁽⁵⁺²⁾·z⁽⁴⁺¹⁾ = 3·2²·x³·y⁷·z⁵
In order to simplify the expression the step Tim needs to use for each variable's exponent is to add the exponents.

–9,45 − 6,1v = –2,8v + 13,98
Answer:
V would equal -7.1.
Step-by-step explanation:
It appears you have set the decimal points as commas. Let's remove that and replace it with decimal points. (AkA ".")
First, we move every term with "V" in this problem to the left.
-9.45 - 3.3v = 13.98
Next, we add -9.45 to 13.98 which equals 23.43.
We then make 3.3v negative.
-3.3v = 23.43
We then divide 23.43 and 3.3v by 3.3.
We cancel out 3.3v to leave 23.43/3.3.
We can now divide 23.43 by 3.3 to get -7.1.
V = -7.1
Answer:
V would equal -7.1.

which of the following mean the same as x-intercept?
Answer:
(A), (D), and (E)
Step-by-step explanation:
In a quadratic function, the solutions are always on the x-axis, which means that it can be another word for x-intercept. Also, a zero and a root are the same thing, and they are both x-intercepts. Hope this helps!
Solve (3^p times 81 = 9) for p
Answer:
p = -2
Step-by-step explanation:
Start by dividing both sides by 81 to get the power by itself.
[tex]3^p \cdot 81 = 9\\\\3^p=\frac{9}{81}=\frac{1}{9}[/tex]
Write the fraction using a power of 3.
[tex]3^p=\frac{1}{3^2}\\\\3^p=3^{-2}\\\\p=-2[/tex]
This assumes you know about negative exponents: [tex]a^{-n}=\frac{1}{a^n}[/tex]

[tex]x^{2}[/tex]+8x+7
Answer:
(x + 1)(x + 7)
Step-by-step explanation:
Assuming you require the expression factored
x² + 8x + 7
Consider the factors of the constant term (+ 7) which sum to give the coefficient of the x- term (+ 8)
The factors are + 1 and + 7 , since
1 × 7 = 7 and 1 + 7 = 8 , then
x² + 8x + 7 = (x + 1)(x + 7) ← in factored form
Which of the following equations can be used to find the missing angle, x, in the triangle below?
Answer:
x+84=180
Step-by-step explanation:
a triangle has a total angle degrees of 180
Answer:
x + 84 = 180
Step-by-step explanation:
The sum of all the interior angles of a triangle is 180. So basically, x plus the other two angles would have to equal 180.

7x+2y=24
8x+2y=30
What is the solution to the system of equation in number 1? Write the y-value or the y- coordinate.
Answer:
X = 6, y=-9
Step-by-step explanation:
7x + 2y =24 equation 1
8x + 2y=30 equation 2
-1(7x + 2y)=-1(24) multiply equation 1 by -1 to eliminate y
-7x-2y=-24 equation 1 multiplied by -1
8x+2y=30 equation 2
x+0=6 add above 2 equations
x=6
solve for y
7x + 2y=24
7(6) + 2y=24
42 + 2y =24
2y=-18
y=-9
check answers
8x + 2y=30
8(6) + 2(-9)=30
48-18=30
30=30
7x + 2y = 24
7(6)+2(-9)=24
42-18=24

Two more than the quotient of a number and 5 is equal to 8
Answer:
30
Step-by-step explanation:
We can start by writing an equation:
2 + x / 5 = 8
We are adding 2 since we are asking for two more than the quotient, and it is set equal to 8 as given by the problem.
We can subtract 2 from both sides to isolate the x term:
2 + x / 5 = 8
-2 -2
x / 5 = 6
Now, we can multiply by 5 to cancel out the division by 5:
x / 5 = 6
* 5 * 5
x = 30
So, the number is 30.
The requried number is 30, and the equation model is x/5 + 2 = 8.
What are equation models?The equation model is defined as the model of the given situation in the form of an equation using variables and constants.
Here,
In the question, we have given a statement, and using that we have to model an equation,
To model an equation 1 step is to assign a variable.
So let the number be x.
According to the quesiton,
Two is more than the quotient of a number and 5 is equal to 8
x/5 + 2 = 8
x/5 = 8 - 2
x /5 = 6
x = 5 × 6
x = 30
Thus, the requried number is 30, and the equation model is x/5 + 2 = 8.
