Answers
Answer:
no your answer is wrong. the answer is 15.6
Step-by-step explanation:
it is a 30-60-90 degree triangle and as per the property ..
the side opposite to 30 degree angle is half of hypotenuse( I. e half of 18 that is 9)
the side opposite to 60 degree angle is √3/2 the hypotenuse.
that is √3/2 * 18
that is √3 * 9
that is 1.73 multiplied by 9 .....(as value of √3 is 1.73)
that is 15.57
rounding it to the nearest tenth it becomes 15.6
answer is 15.6 not 20.1

Angles 1 and 2 are supplementary. If angle 1 measures (2x +2)°, and angle 2 measures (x - 5)° what is the measure of each angle?
Answers
Answer:
angle 1 is = 124 angle 2 is = 56
Step-by-step explanation:
supplementary angles always add up to 180 so you can set up the equation (2x+2)+(x-5)=180 to find x. After solving you get x = 61 and then once you have x you plug it into the 2 equations you got for the angles to solve for 1 and 2.

Answers
Given:
Last year 80 students signed up for a summer trip to Washington, D.C.
This summer 50 students have signed up to go.
To find:
The percent decrease in the number of students.
Solution:
We have,
Students in last year = 80
Students in this year = 50
Now,
[tex]\text{Decrease}\%=\dfrac{\text{Students in last year - Students in this year }}{\text{Students in last year }}\times 100[/tex]
[tex]\text{Decrease}\%=\dfrac{80-50}{80}\times 100[/tex]
[tex]\text{Decrease}\%=\dfrac{30}{80}\times 100[/tex]
[tex]\text{Decrease}\%=\dfrac{3}{8}\times 100[/tex]
[tex]\text{Decrease}\%=37.5[/tex]

What is a diameter?A straight line that runs through the sideways of a body or figure, particularly a circle or sphere, is called as a diameter of a circle or sphere.
Given:
A rug is circular.
And diameter = 9 feet.
So, the radius of the circle is = 4.5 feet.
The area of floor space will the rug cover,

Solve the system by substitution. x= 2y + 7 3x – 2y = 3 The solution is?
Answers
Hi there! Your answer is x = -2, y = -9/2
In coordinate point, we can write (-2,-9/2)
Please see the explanation below for a clear understand about the problem.
Any questions about the answer, feel free to ask in comment! :)
Step-by-step explanation:
Goal
Solve the system of equations by substitution method.Given
System of Equations[tex]\begin{cases} x=2y+7 \Longrightarrow (1)\\ 3x-2y=3 \Longrightarrow (2) \end{cases}[/tex]
Step 1
Since our x-term is the subject in the first equation, we can simply substitute x = 2y+7 in the second equation.Substitute x = 2y+7 in the second equation.
[tex]3x-2y=3\\3(2y+7)-2y=3[/tex]
We do this so we can solve for the y-term without any problems. (We need to get rid of a variable if there are more than one variable.)
Then we distribute/expand 3 in the expression.
[tex]6y+21-2y=3\\4y+21=3[/tex]
Step 2
Solve the equation for y-termTo solve the equation, we have to isolate the term that we want. For this scenario, we want to know the value of y-term. Therefore, we isolate y-term.
[tex]4y=3-21\\4y=-18\\y=-\frac{18}{4} \\y=-\frac{9}{2}[/tex]
Finally! we know the value of y which is -9/2. But we are not done yet!
Step 3
Substitute the y-value in any given equations.After we solve the equation, we have to substitute the value in any given equations. No need to substitute the value in both equations! Choose an equation to substitute the value in.
For this, I will be choosing an equation with less coefficients which is the first equation.
[tex]x=2y+7[/tex]
Substitute y = -9/2 in the equation.
[tex]x=2(-\frac{9}{2})+7\\x=-9+7\\x=-2[/tex]
We should get x = -2 as the answer. This is our last step for finding an answer. The next few steps are going to be how to check the answer for system of equations. Note that next few steps are optional. If you are not certain that the answer is wrong or right, it is highly advised to check the answer before jumping to a conclusion!
Optional Steps - Answer Check
To check the answer, we can simply substitute both x-value and y-value in any given equations. You can either choose only a single equation to substitute in ONLY if you are certain/sure that the answer is likely correct. Substituting in both equations are recommended for beginners.
Step 3
Substitute x = -2 and y = -9/2 in the system of equations.Step 3.1
Substitute in x = 2y+7[tex]x=2y+7[/tex]
From x = -2 and y = -9/2
[tex]-2=2(-\frac{9}{2} )+7[/tex]
Cancel 2 out.
[tex]-2=-9+7\\-2=-2[/tex]
As you can see, both sides are equal. That means the equation is true for x = -2 and y = -9/2.
Step 3.2
Substitute in 3x-2y = 3[tex]3x-2y=3[/tex]
Substitute x = -2 and y = -9/2 in the equation.
[tex]3(-2)-2(-\frac{9}{2})=3\\-6+\frac{18}{2}=3\\-6+9=3\\3=3[/tex]
Since both equations are true for x = -2 and y = -9/4. We can conclude that:
[tex]\huge\sf{x = -2 \ and \ y = -\frac{9}{2} \ are \ the \ solutions \ to \ the \ system \ of \ equations.}[/tex]
Hence, the answer is x = -2 and y = -9/2.

what are the x and y intercepts for this equation y=−1/4x+2?
(_,_)
Answers
Answer:
(8, 0) is the x-intercept
(0, 2) is the y-intercept
Step-by-step explanation:
The y-intercept = 2 since the equation is in slope-intercept form.
The x-intercept occurs when y = 0
So, 0 = -1/4x + 2
0 = -x + 8
x = 8
(8, 0) is the x-intercept
(0, 2) is the y-intercept

Anthony bought an 8-foot board. He cut off 3/4 of the board to build a shelf, and gave 1/3 of the rest to his brother for an art project. How many inches was the piece Anthony gave to his brother.
Answers
Answer:
8 inches
Step-by-step explanation:
Anthony bought an 8-foot board. He cut off 3/4 of the board to build a shelf
Step 1
The amount of board he used to build the shelf is calculated as:
= 3/4 of 8 foot board
= 3/4 × 8 foot
= 6 foot board.
Step 2
The amount of board left after building the shelf = The rest =
8 foot - 6 foot
= 2 foot
Step 3
We are told that he gave 1/3 of the rest to his brother for an art project
The amount of board he give his brother for an art project =
1/3 × 2 foot
= 2/3 foot
Step 4
How many inches was the piece Anthony gave to his brother?
We convert 2/3 foot to inches
1 foot = 12 inches
2/3 foot = x inches
Cross Multiply
x inches = 2/3 foot × 12 inches
x inches = 8 inches
Therefore, Anthony gave his brother 8 inches of board.

Hi! I hope this helps a bit because I'm just gonna give a few things you can talk about...I'm not writing a whole essay lol...
School impacts us in an extremely large variety of ways. Personally, I think it has more negative effects than positive. For example, at a school environment, there are so many ways to get exposed to profanity by your peers. There are definitely ways to be engaged with people who impact your entire life because of swearing. Similarly, students can learn and get very involved in having horrible behavior. Last but not least, I know that bullying is a huge problem at school. Even if it's being done unintentionally, students can really harm both the physical and mental strength of others.
I hope this helps you out...have a great day ❤

In a shipment of shirts to a clothing store, 2/5 of the shirts are blue and 3/10 of the shirts are red. If there are 20 shirts in the shipment, how many shirts are either blue or red?
Answers
Answer: 14
Step-by-step explanation:
Fraction of blue shirts = 2/5
Fraction of red shirts = 3/10
Number of shirts in the shipment = 20
The number of shirts that are either blue or red will be:
= (2/5 + 3/10) × 20
= (4/10 + 3/10) × 20
= 7/10 × 20
= 14
The number of shirts that are either blue or red is 14
