Answer:
B. 4 square feet
Step-by-step explanation:
The formula for area of a triangle is length x height / 2 so 4 x 2 is 8 then divided by 2 is 4.
Answer: 4
Base 4
hight 2
4x2=8 ÷ 2 or 1/2 Equals 4

15 men can build a wall in 20 days. How long will 25 men take to build the
same wall?
Answer:
Step-by-step explanation:
no of men no of days
15 20
25 let be x
it is in indirect proportion
15/25=x/20
do cross multiplication
25*x=20*15
25x=300
x=300/25
x=12
therefore ot will take 12 day to complete the same wall by 25 men.

The OLS residuals in the multiple regression model: A) cannot be calculated because there is more than one explanatory variable. B) can be calculated by subtracting the fitted values from the actual values. C) are zero because the predicted values are another name for forecasted values. D) are typically the same as the population regression function errors.
Answer:
B) can be calculated by subtracting the fitted values from the actual values.
Step-by-step explanation:
'Multiple Regression Model' is characterized as the further augmentation of the 'linear regression model.' which is employed to predict a dependent variable's value on the basis of other provided variables(independent). It also helps in showing the linear association among these variables.
In this model, the OLS residuals can be determined by deducting the adapted values from the real values. Thus, there would be a subtraction of the calculated value from the predicted value to find the value of residual. The 'distinction between the actual and fitted values itself is characterized as the residual.' Therefore, option B is the correct answer.

What is the distance between points L(−5, 7) and M(3, −8)?
Answer:
17
Step-by-step explanation:
√(3-(-5))²+(-8-7)²
√(3+5)²+(-15)²
√8²+225
√64+225
√289
=17
The distance between two points L(-5, 7) and M(3, -8) is 17 units.
What is distance ?Distance is a numerical measurement of how far apart objects or points are. In Physics or everyday usage, distance may refer to a physical length or an estimation based on other criteria.
Here Distance formula = [tex]\sqrt{(x_{2}-x_{1})^{2} + (y_{2}-y_{1})^{2} }[/tex]
Distance = [tex]\sqrt{(3-(-5))^{2} + (-8-7)^{2} }[/tex]
D = [tex]\sqrt{8^2+15^2}[/tex]
D =[tex]\sqrt{64 + 225}[/tex]
D = [tex]\sqrt{289}[/tex]
D = 17 units
Thus, the distance between two points L(-5, 7) and M(3, -8) is 17 units.

The zeros of a parabola are 6 and -5. If (-1, 3) is a point on the graph, which equation can be solved to find the
value of a in the equation of the parabola?
O3 = a(-1 + 6)-1-5)
O 3 = a(-1-6)(-1 +5)
O -1 = a(3+6)(3-5)
O-1 = a(3-6)(3+5)
Answer:
3 = a(-1-6)(-1+5).
Step-by-step explanation:
y = a(x - 6)(x + 5)
When x = -1, y = 3 so we have:
3 = a(-1-6)(-1+5).
Lorenzo wants to know how much it will cost to rent tables and chairs for an event. He investigates renting tables and chairs and decides to use two different companies. Company A $4 per table (seats 4) and a $25 one-time delivery and pickup fee Company B $2 per chair and a $15 one-time delivery and pickup fee Each table seats 4 people, so Lorenzo needs to rent 4 chairs for every table. x = number of tables Cost to rent tables from Company A: f(x) = 4x + 25 Cost to rent chairs from Company B: g(x) = 2(4x) + 15 Which function represents the total cost for Lorenzo to rent x number of tables and the chairs he needs to go with them? 12x 12x2 + 40 12x + 40 8x + 40
Answer:
C: 12x + 40
Step-by-step explanation:
We are told that the Cost to rent tables from Company A is;
f(x) = 4x + 25
Also, we are told that the Cost to rent tables from Company B is;
g(x) = 2(4x) + 15
Thus, total cost for Lorenzo to rent x number of tables and the chairs he needs is;
Total = f(x) + g(x)
Total = 4x + 25 + 2(4x) + 15
Total = 4x + 25 + 8x + 15
Total = 12x + 40

the answer is c

If 6 is added to x, the result is 17. Find the value of x.
Answer:
Step-by-step explanation:
To find x, we need to do opposite operations.
x+6=17
Subtract 6 from both sides, since subtraction is the opposite of addition, thus cancelling the 6 out.
x+6=17
-6 -6
x=11
So x is 11.

1. AC=EC
2.BC=DC
3.AB=DE
Answer:
1. AC = EC
Step-by-step explanation:
As it says that the figure has to be proved by SAS postulate. We know that, SAS stands for Side - Angle - Side, so we need to prove that any two sides and one angle of two triangles are equal/proportional or not.
Given, BC = CD, and angle ACB = angle DCE.
Therefore, the answer is 1. AC = EC.

The area of a rectangle is 14 in. The length of one side is 7 in. What is its perimeter?
Answer:
The answer is 18
hope this helps
have a good day :)
Step-by-step explanation:
Answer:
The perimeter of the rectangle =18 in
Step-by-step explanation:
Given, Area of rectangle= 14 in
Length(l) of one side = 7 in
We know,
Area = lxb
or, 14 = 7xb
or, b = 2 in
then the perimeter of the rectangle = 2x(l+b)
= 2x(7+2)
= 2x9

two objects are 2.4*10^20 centimeters apart. a messages from one object travels to the other at a rate of 1.2*10^5 centimeters per second. how many seconds does it take the message to travel from one object to the other
Answer:
2 · 10¹⁵ seconds
Step-by-step explanation:
1.2 · 10⁵
2.4 · 10²⁰
2.4 · 10²⁰ ÷ 1.2 · 10⁵
2 · 10²⁰ ⁻ ⁵
2 · 10¹⁵
It took the message 2 × 10¹⁵ seconds to travel from one object to the other.
To be able to solve this problem, we need to understand the relation between speed and distance.
What are Speed and Distance?Speed is the change of an object's position with time, the distance is the space covered with a specified range of time.
The relation between Speed and distance can be expressed by using the relation:
[tex]\mathbf{speed = \dfrac {distance}{time}}[/tex]
From the parameters given:
Speed = 1.2 × 10⁵ cm/sDistance = 2.4 × 10²⁰ cm Time = (unknown)???The time it took the message to travel from one object to the other can be determined by making time(t) the subject of the formula from the above equation:
i.e.
[tex]\mathbf {time = \dfrac{distance} {speed}}[/tex]
[tex]\mathbf {time = \dfrac{2.4 \times 10^{20}\ cm} {1.2 \times 10^5 \ cm/s}}[/tex]
time = 2 × 10¹⁵ seconds

Find the quotient of z1 by z2. .Express your answer in trigonometric form.
Answer:
[tex]\frac{z_1}{z_2} = 3(cos(240^o) + isin(240^o))[/tex]
Step-by-step explanation:
Given
[tex]z1 = 12(cos(320^o) + isin(320^o))[/tex]
[tex]z2 = 4(cos(80^o) + isin(80^o))[/tex]
Required
[tex]Quotient = \frac{z_1}{z_2}[/tex]
We have:
[tex]Quotient = \frac{12(cos(320^o) + isin(320^o))}{4(cos(80^o) + isin(80^o))}[/tex]
Divide 12 by 4
[tex]Quotient = \frac{3(cos(320^o) + isin(320^o))}{(cos(80^o) + isin(80^o))}[/tex]
Solve using the following rule:
[tex]\frac{(cos(a) + isin(a))}{(cos(b) + isin(b))} = \cos(a - b) + isin(a - b)[/tex]
So, we have:
[tex]Quotient = \frac{3(cos(320^o) + isin(320^o))}{(cos(80^o) + isin(80^o))}[/tex]
[tex]Quotient = 3(cos(320^o-80^o) + isin(320^o-80^o))[/tex]
[tex]Quotient = 3(cos(240^o) + isin(240^o))[/tex]
Hence:
[tex]\frac{z_1}{z_2} = 3(cos(240^o) + isin(240^o))[/tex]

Their results showed that adolescents who experienced more video game violence were also more hostile and had more frequent arguments with teachers. Is this an experimental or a nonexperimental study? Explain your answer.
Answer: nonexperimental study
Instead, this is a survey

We have a survey being conducted because the researchers are asking the students the questions. It's not an experiment because the students aren't being broken up into two groups (control group vs treatment group) to see the difference between the two if any.

Part b: B 71 degrees.
Step by step explanation: The figure above is a right angle split into two parts, making it a complimentary angle. Since you have the measure of AB which is 19 degrees, you now subtract that from 90 because it is a right angle. 90-19= 71, making B the correct answer.
