Answer: 19
Step-by-step explanation:
75 papers need to be marked
He grades 7 papers per hour
To find out how many paper he graded in 8 hours:
7 x 8
(7 is the number of papers graded in an hour)
(8 is the number of hours)
7 x 8 = 56
(56 is the number of papers he graded in 8 hours)
Now, there was a total of 75.
To find the remaining number of test sheets:
75 - 56
(75 is the total number of papers)
(56 is the number of papers graded)
75 - 56 = 19
Therefore, there are 19 papers remaining to grade.
Find the area of the polygon.
Answer: 72
Step-by-step explanation: 6*2=12 6*10=60 Normally you would divide by 2 to get triangles but since there are two of each, you don't.
Answer:
Solution given:
diagonal 1=AC=6+6=12units
diagonal 2=BD=2+10=12units
area of polygon (rhombus)=½*(diagonal 1*diagonal 2)
=½(12*12)=12*6=72square units
Area=72square units

The equation y=250,000(1.1)x closely models the value of his home, y, when x is the number of years since 2002.
Using this equation, what would we have expected to be the value of his condo in the year 2006?
Value in 2006:
Answer:
The value in 2006 is 366,025
Step-by-step explanation:
Here, we want to get the value of y in 2006
what we have to do here is to find and substitute the missing value of x
The missing value x is the difference between the number of years in 2002 and 2006
we have this as 2006-2002 = 4
so we have to substitute 4 here for x
Thus, we have this as;
y = 250,000(1.1)^4
y = 366,025
Use the functions f(x)=10-9/2x, g(x)=|-3x+16|, and h(x)=-x^2+8
Find h(a-4). urgent please answer
The value of h(a -4) is -a² + 8a - 8
What is a function?
A function can be defined as an expression or rule that explains the relationship between a dependent and an independent variable.
Given the functions;
f(x)=10-9/2x g(x)=|-3x+16| h(x)=-x^2+8To determine h(a-4), we substitute the value of x as a - 4 in the h(x) function, we have;
h(a - 4) =- (a - 4)² + 8
expand the bracket
h(a - 4) = - ( a - 4)(a - 4) + 8
h(a - 4) = - (a²- 4a - 4a + 16) + 8
collect like terms
h(a - 4) = - a² + 8a -16 + 8
h(a - 4) = -a² + 8a - 8
Thus, the value of h(a -4) is -a² + 8a - 8

what is the volume of the rectangular pyramid shown
Answer:
80 cm^3 = V
Step-by-step explanation:
The volume of a rectangular pyramid of base area A and height h is
V = (1/3)(base)(height).
Given that the dimensions of the base are L = 10 cm and W = 4 cm, the base area is 40 cm^2.
The height of the pyramid is h = 6 cm.
Therefore the volume of this particular pyramid is
V = (1/3)(40 cm^2)(6 cm), or V = 80 cm^3

Relationship a is defined by the equation y=9x some values of relationship b are (0,0)(3,34.5)(5,57.5)(8,92) both relationships have a direct proportion between x and y. The rate of change of relationship b is how many units greater then the rate of change of relationship a
Answer:
The rate of change of relationship 'b' is 2.5 times greater than the rate of change of relationship 'a'
Step-by-step explanation:
The given parameters are;
The function representing relationship 'a' is y = 9·x
Some values of relationship 'b' are;
(0, 0), (3, 34.5), (5, 57.5), and (8, 92)
For direct proportionality of relationship 'b' we have;
y = k₂·x
∴ k₂ = y/x
∴ k₂ = 34.5/3 = 23/2
57.5/5 = 23/2
92/8 = 23/2
k₂ = 23/2
Therefore, the direct proportionality relationship of relationship 'a' is y = 9·x
∴ k₁ = 9
Therefore, the rate of change of relationship 'b' is k₂ - k₁ = (23/2) - 9 = 2.5 times greater than the rate of change of relationship 'a'.

1. What is the mass of an object if it takes a net force of 25 N to accelerate it at a rate of 0.88 m/s2?
Answer:
28.4 kg
Step-by-step explanation:
F = ma
F is 25 N and a is 0.88 m/s^2
25 = 0.88m
Divide both sides by 0.88
m = 28.4 kg
The mass of an object is 28.4 kg.
It is required to find the mass of an object.
What is force?The capacity to do work or cause physical change; energy, strength, or active power. The push or pull on an object with mass causes it to change its velocity. Force is an external agent capable of changing a body's state of rest or motion. It has a magnitude and a direction.
Given:
Net force = 25 N
Acceleration=0.88 m/s^2
According to given question we have,
F = ma
25 = 0.88m
Divide both sides by 0.88
m = 28.4 kg
Therefore, the mass of an object is 28.4 kg.

Solve for t. You must write your answer in fully simplified form.
−19=7t
Answer:
t=-19/7
Step-by-step explanation:
you need to isolate for t which means you need to get t all alone on one side of the equation. Do do that you can divide both sides by 7. This gives you -19/7=7t/7
we know that anything divided by itself is 1 so we get -19/7=t
This is the simplest for because 19 and 7 are both prime numbers, so you can't simplify them.

The school cafeteria sells two kinds of wraps: vegetarian and chicken. The vegetarian wraps cost $1.00 and the chicken wraps cost $1.50. Today they made $149.00 from the 105 wraps sold. How many wraps sold were vegetarian?
Answer:
17 wraps
Step-by-step explanation:
Given data
let the number of vegetarian wraps be x
and chicken wraps be y
so
x+1.5y= 149------------1
and
x+y= 105----------------2
the systems of equation for the problem is
x+1.5y= 149
x+y= 105
from 2
x= 105-y
put this in 1
105-y+1.5y= 149
105-0.5y= 149
-0.5y= 149-105
-0.5y=44
y= 44/0.5
y= 88
put y = 88 in 2
x+88= 105
x= 105-88
x= 17
point B is the image of the point A when A is rotated 90° counterclockwise around the origin
point B must be the same ________ from the origin as point A
Answer:
distance
Step-by-step explanation:
Point B must be the same distance from the origin as point A.
What is Rotation?Rotation is a kind of geometric transformation where a figure or point is rotated by a certain degrees about a given point.
Given that,
Point B is the image of the point A when A is rotated 90° counterclockwise around the origin.
A point P(x, y) after the rotation of 90°counterclockwise around the origin is P'(-y, x).
So the x coordinate changes to the negative of y coordinate and y coordinate changes to x coordinate.
Distance between P(x, y) from origin (0, 0) is √(x² + y²)
Similarly the distance P'(-y, x) from origin (0, 0) is √((-y)² + x²) = √(x² + y²)
Hence they are at the same distance.

If Amber decides to mail copies of her photo to the 45 residents of her grandmother's assisted living facility, the new function representing her photo shares is f(x) = 3(4)x + 45. How does this graph compare with the original graph of Amber's photo share?
Answer:
We know that Amber decided to mail copies of her photo to the 45 residents of her grandmother's assisted living facility, and after this, the function representing the photo shares is:
f(x) = 3*(4)^x + 45
We do not know the initial function, but with the given information we can assume that the original equation is:
g(x) = 3*(4)^x
Then the new function is:
f(x) = g(x) + 45.
This is a vertical translation, remember that for a function h(x), a vertical translation of N units is written as:
k(x) = h(x) + N
if N is positive, we have a translation of N units up
if N is negative, we have a translation of N units down.
in this case we have;
f(x) = g(x) + 45
This means that f(x) is a vertical translation of 45 units of g(x), then:
the graph of the new function is 45 units above the original function.
