58,743
-------------
41,257
The amount that is needed to reach the goal is $41257 if the annual fundraising goal of a college is $100,000. so far $58,743 has been raised.
What is a linear equation?It is defined as the relation between two variables, if we plot the graph of the linear equation we will get a straight line.
If in the linear equation, one variable is present, then the equation is known as the linear equation in one variable.
It is given that:
The annual fundraising goal of a college is $100,000.
Let x be the amount that is needed to reach the goal.
The linear equation in one variable can be framed as follows:
x + 58,743 = 100,000
x = 100,000 - 58,743
x = $41257
Thus, the amount that is needed to reach the goal is $41257 if the annual fundraising goal of a college is $100,000. so far $58,743 has been raised.

GivenCM = MKMidpointNKMAlternate InteriorCMEVerticalASA======================================================
Explanations:
Always start with the given statements and build toward the thing you want to prove. The first line(s) will basically be restating the given facts word for word.
The term "bisect" means to "divide in two equal pieces". Angle ABC is split into the two equal pieces of angles ABD and CBD, hence ABD = CBD. Segment CK is split into the equal pieces of CM and MK, meaning that CM = MK.
The reflexive theorem says any segment is congruent to itself, so BD = BD.
Vertical angles are formed when we intersect two lines to form an X shape. The vertical angles are opposite one another and always congruent.
Alternate interior angles are always congruent when we have parallel lines.
The AAS (angle angle side) congruence theorem says that two triangles are congruent if we have two pairs of congruent angles, and a pair of congruent sides. The congruent sides are not between the angles mentioned. The order matters.
AAS is slightly different from ASA. With ASA, the congruent sides are between the congruent angles.

An empty lorry weighs 3500kg. It weighs 7250 kg when loaded with 50 bags of coffee .What is the average mass of each bag ?
Answer:
The average mass of one coffee bag is 75kg.
Step-by-step explanation:
The lorry on its own weighs 3500kg.
If it weighs 7250kg alongside coffee bags, we can make the assumption that to find the total mass of the coffee bags, we must take the combined total and subtract the lorry's weight from it.
7250kg subtract 3500kg is 3750kg.
There are 50 coffee bags, so this is the mass of all 50.
If we want to find the mass of one coffee bag, we have to divide the mass of 50 coffee bags by 50.
3750kg divided by 50 is 75kg.
The average mass of one coffee bag is 75kg.

In a random sample of 200 items, 5 items were defective. An estimate of the percentage of defective items in the population is Group of answer choices 2.5% 200 5.0% 10.0%
An estimate of the percentage of defective items in the population if 5 of 200 items were defective is 2.5%.
How to calculate percentage?The percentage of a defective item out of a total item can be calculated as follows:
% defective item = no of defective item/total no of items × 100
According to this question, in a random sample of 200 items, 5 items were defective.
% defective item = 5/200 × 100
% defective item = 2.5%
Therefore, an estimate of the percentage of defective items in the population if 5 of 200 items were defective is 2.5%.

Answer:
5x^2 - 4x - 3 = 0
Step-by-step explanation:
For the equation
ax^2 + bx + c = 0
the roots are [-b +/- √(b^2 - 4ac)] / 2a
So comparing the terms to the values in the question:
a = 5
b = -4
c = -3
the fully simplified form of 2ab÷(8a) is:
A) [tex]\frac{2ab}{8a}[/tex] B) [tex]\frac{4}{b}[/tex] C) [tex]\frac{b}{4}[/tex] D) 4b E) 4a
Answer:
b/4
Step-by-step explanation:
After rewriting the quotient as a fraction,
[tex]\dfrac{2ab}{8a}[/tex]
We can look for common factors to reduce it. 8a and 2a both have the common factor 2a, and since 2a = 1 · 2a and 8a = 4 · 2a, we can reduce our fraction down to
[tex]\dfrac{1\cdot2a\cdot b}{4\cdot2a}=\dfrac{1\cdot b}{4}=b/4[/tex]

n (a)–(e), say whether the quantity is changing in a linear or exponential fashion. a. A savings account, which earns no interest, receives a deposit of $723 per month.
Using function concepts, it is found that since the savings account receives no interest, the quantity is changing in a linear fashion.
When is a function changing in linear and in exponential function?If the rate of change is a constant value, the change is linear.If the rate of change involves a proportion or a percentage, the change is exponential.In this problem, the rate of change is a constant of $723 each month, hence the quantity is changing in a linear fashion.

O slope: 2, y-intercept: -20
Oslope: 2, y-intercept: 10
Oslope: 5, y-intercept: -20
O slope: 5, y-intercept: 10
The slope of the line is 2 and y-intercept is -20 and the linear equation can be framed as y = 2x—20 option first is correct.
What is a straight line?A straight line is a combination of endless points joined on both sides of the point.
The slope 'm' of any straight line is given by:
[tex]\rm m =\dfrac{y_2-y_1}{x_2-x_1}[/tex]
Taking two points to find the slope of the line:
(0, -20) and (5, -10)
