29 What is the length of a rectangle with width 10 in. and area 45 in.²?
Answer:
l=4.5
Step-by-step explanation:
The area of a rectangle is length times width.
Area = LW
L = length
W = width
L = Area / W
L = 45 / 10
L = 4.5
In the diagram below, the three lines intersect in the same point,
forming six numbered angles
Answer:
A , B, D, F
Step-by-step explanation:
A) ∠1 ≅ ∠ 4 {Vertically opposite angles are congruent}
B) m∠2 + ∠4 + ∠6 = 180° {Straight line angles}
∠6 ≅ ∠3
⇒ ∠2 + ∠4 + ∠3 = 180°
D) ∠2 + ∠3 + ∠4 = 180° {Straight line angles}
f) ∠2 + ∠3 = ∠5 + ∠6 {Vertically opposite angles}

The equation in slope-intercept form of the line passing through the given points is, y = (-1/2)x + 1
A table containing values of x and y is given:
x y
-2 2
0 1
2 0
4 -1
So the points on the line are:
(-2,2), (0,1), (2,0) and (4,-1)
The equation in slope-intercept form of a line is,
y = mx + c,
where m is the slope of the line and c, the y-intercept of the line.
So we need to find the slope and the y-intercept of the line from the given table values.
Let (x₁, y₁) = (-2,2) and (x₂, y₂) = (0,1).
Then slope of the line, m = (y₂-y₁)/(x₂-x₁)
= (1-2)/(0- -2)
= -1/2
The y-intercept of a line is the y-co-ordinate of the point which intersect the y-axis. I.e., it is the y-co-ordinate of the point at which x = 0.
From the table, when x = 0, y = 1.
Hence the y-intercept, c = 1.
So finally, the equation in slope-intercept form of the line is,
y = (-1/2)x + 1

The cookie jar contains three types of coolcies: chocolate chip, sugar and oatmeal. There are 3 times as many chocolate chip as sugar cookies, and 12 more oatmeal than chocolate chip. If there are 54 cookies in the jar, how many oatmeal cookies are there?
By solving equations, we can conclude that there are 30 oatmeals in the jar.
What are equations?A mathematical equation is a formula that uses the equals sign to represent the equality of two expressions. A mathematical statement known as an equation is made up of two expressions joined together by the equal sign. A formula would be 3x - 5 = 16, for instance. When this equation is solved, we discover that the value of the variable x is 7.So, a number of oatmeals are in the jar.
Let, sugar cookies be 'x'.Chocolate chips are '3x'.Oatmeals be '3x + 12'The total number of cookies is 54.
From the equation:
x + 3x + 3x + 12 = 54Now, solve for 'x' as follows:
x + 3x + 3x + 12 = 547x + 12 = 547x = 54 - 127x = 42x = 42/7x = 6Number of oatmeals when "x = 6':
3x + 123(6) + 1218 + 1230Therefore, by solving equations, we can conclude that there are 30 oatmeals in the jar.

Answer: the answer is (0,-8)
Solve the quadratic equation x2 + 3x = 40 using the quadratic formula.
A)
x = –8, x = 5
B)
x = 5, x = 8
C)
x = –5, x = 8
D)
x = –8, x = –5
After solving the quadratic equation x² + 3x = 40 using the quadratic formula, (A) x = –8, x = 5
We can solve this quadratic formula by following a few steps.
The given equation is,
x² + 3x =40
Let's subtract 40 from both sides,
x² + 3x - 40 =40 - 40
Or, x² + 3x - 40 = 0
Now, we have to find a suitable pair of factors of -40 which is capable to generate +3 ( coefficient of x ).
The required pair is 8 and -5, and ( 8 - 5 ) = 3
[ -40 = 8 × -5 ]
Therefore, x² + 3x - 40 = 0
Or, x² + ( 8 - 5 )x - 40 = 0
Or, x² + 8x - 5x - 40 = 0
Or, x ( x + 8 ) - 5 ( x + 8 ) = 0 [ taking x and 5 as common ]
Or, ( x + 8 ) ( x - 5 ) = 0 [ taking ( x + 8 ) as common ]
If the multiplication or product of two or more terms is zero, then we can write each term as zero.
Hence we can write,( x + 8 ) = 0
Or, x = -8 ( by subtracting 8 from both sides )
Again we can write,( x - 5 ) = 0
Or, x = 5 ( by adding +5 with both sides )
Now, we can conclude that x = -8 and 5.

use the graph to determine wither the function is even, oddPlease check photo
EXPLANATION:
Given;
We are given a graph of a function.
Required;
We are required to determine from the graph if the function is even, odd or neither even nor odd.
Solution:
To determine this from a graph, we should note that a function which is symmetrical with the y-axis is an even function. The graph which is symmetrical with the origin after a 180 degree rotation is an odd function.
Observe that if this graph is flipped from left to right (across the y-axis), it would not retain its original shape.
However, if the graph is rotated 180 degrees about the origin, it would retain its original shape.
Therefore, the graph depicted is an odd function

The function is an ODD function

What is a function?A function is a relationship between inputs where each input is related to exactly one output.
A function has an input and an output.
Example:
f(x) = x + 1
f(1) = 1 + 1 = 2
Input = domain = 1
Output = range = 2

3(5-x)-2(5+x)=3(x+1) solve for x
Primarily use the Distributive Property to solve this equation.
3(5 - x) - 2(5 + x) = 3(x + 1)
Distribute the outer terms.
3(5) + 3(-x) - 2(5) - 2(x) = 3(x) + 3(1)
15 - 3x - 10 - 2x = 3x + 3
-3x - 2x + 15 - 10 = 3x + 3
-5x + 5 = 3x + 3
Now, isolate all x terms.
-5x + 5x + 5 = 3x + 5x + 3
5 = 8x + 3
5 - 3 = 8x + 3 - 3
2 = 8x

What is Pythagoras' Theorem?The Pythagorean theorem, sometimes known as Pythagoras' theorem, is a fundamental relationship between a right triangle's three sides in Euclidean geometry.According to this statement, the areas of the squares on the other two sides add to the area of the square whose side is the hypotenuse.In the given triangle,
∠ADC = ∠BDC = 90°
Hence the triangles ΔACD and ΔBCD are right-angle triangles. Thus we can apply Pythagoras' theorem in both triangles.
So in ΔACD,
CB² = BD² + DC²
And in ΔBCD,
CA² = AD²+ DC²
But, CA = 15 and CB = x + 5
So, (x + 5)² = BD² + DC²
15² = AD² + DC²
⇒225 = AD² + DC²
Here, BD = AD as given in the figure
Replacing BD with AD in the first equation we get,
(x + 5)² = AD² + DC²
Now, equate the values of AD² + DC² to obtain the value of x,
(x + 5)² = 225
⇒ x² + 25 + 10x = 225
⇒ x² + 10x - 200 = 0
⇒ x² + 20x - 10x - 200 = 0
⇒x(x + 20) - 10(x + 20) = 0
⇒(x + 20)(x - 10) = 0
Thus x = -20, 10
Hence the value of x is 10.

The percent error of Ming’s estimate is 40%.
What is Algebraic expression ?
Algebraic expressions are the idea of expressing numbers using letters or alphabets without specifying their actual values. The basics of algebra taught us how to express an unknown value using letters such as x, y, z, etc. These letters are called here as variables. An algebraic expression can be a combination of both variables and constants. Any value that is placed before and multiplied by a variable is a coefficient.
here, it is given that :
Estimated number of members in his bicycle club by the end of summer = 21
Actual number of members in his bicycle club by the end of summer = 15
Now, the percent error of Ming’s estimate :
percent error = {(21-15)/15 } x 100
percent error = (6/15) x 100
percent error = 40%
Therefore, the percent error of Ming’s estimate is 40%.
