Which number from the set {0, 2, 3, 5} is the solution to this equation?
5x − 4 = 3x + 6
A) 0
B) 2
C) 3
D) 5
Answer:
The answer is D: 5
Step-by-step explanation:
5 x 5 = 25 - 4 = 21 and 3 x 5 = 15 + 6 = 21
Answer: 5
Step-by-step explanation: Here, we want to determine which number can be replaced for the variable in this problem so the statement holds true.
5 would be the only number in this set that can work. Let's test it out.
We can do this by simply plugging in 5 for x. If the statement holds true when 5 is plugged in for x, then 5 is a solution.
Plugging in 5 for x, we have 5(5) - 4 = 3(5) + 6.
Simplifying, we have 25 - 4 = 15 + 6 or 21 = 21 which is a true statement.
So 5 is a solution.
33. Calista earns $300 per week for a 40 hour work week plus $12.32 per hour for each hour of
overtime after 40 hours. Write an equation that would be used to determine her weekly wages
where w is her wages, and v is the number of overtime hours worked.
Answer:
w = 300 +12.32v
Step-by-step explanation:
Calista's wages are ...
wages = (straight time earnings) + (overtime pay)
= $300 + (overtime hours)·(overtime pay per hour)
= $300 + (v)($12.32)
Using the symbols required by the problem statement, we have ...
w = 300 + 12.32v
Charles opened a door hinged at O by an angle of 45 degrees. The width of the door was 80 centimeters. Find the area swept by the door. Leave your answer in terms of pie
Answer:
A=800πcm²
Step-by-step explanation:
Knowing that the area of a circular sector is:
[tex]A_{cs}=\frac{\pi\alpha r^{2}}{360}[/tex]
where α is the sweep angle and r in the radio (according to the graph),
then
A=(45° π 80²)/360° = 800πcm²
Final answer:
The area swept by the door is 10π cm and the area of the sector is 200π cm².
Explanation:
To find the area swept by the door, we can first find the length of the arc created by the door when it opens. The arc length formula is given by:
Arc length = r × θ
Where r is the radius (half the width of the door) and θ is the angle through which the door opens. In this case, the radius is 40 centimeters (half of 80 centimeters) and the angle is 45 degrees.
So, the arc length = 40 cm × (45 degrees) = 40π/4 cm = 10π cm
The swept area can be approximated by treating it as a sector of a circle with radius 40 cm and central angle 45 degrees. The area of the sector is given by:
Area = (θ/360) × π × r²
Where θ is the central angle and r is the radius. Substituting the values, we get:
Area = (45/360) × π × (40 cm)² = 1/8 × π × 1600 cm² = 200π cm²

so the hours are the y-axis and you can label them 2,4,6,8 because skip counting by twos are probably the easiest! so for the first question, you would line a dot up on top of 1 and go up and you see 2 and 4 right, cuz you just labeled it... do go between 2 and 4 which is 3 and place the dot there...
and keep doing the same things with other ones too...

y = 75
Solution:
In a straight line, sum of the adjacent angles = 180°
80° + m∠DGF = 180°
Subtract 80° from both sides of the equation.
m∠DGF = 100°
Sum of all the interior angles in a quadrilateral = 360°
m∠DGF + m∠GFE + m∠FED + m∠EDG = 360°
100° + 120° + 65° + y° = 360°
285° + y° = 360°
Subtract 285° from both sides, we get
y° = 75°
Hence the value of y is 75.
−x+4y=−9

Is (2,3)(2,3)left parenthesis, 2, comma, 3, right parenthesis a solution of the system?
The solution of the equation 4y − x + 9 = 0 and y = 6 − 2x will be (11/3, −4/3). Point (2, 3) is not the solution of the system.
What is the solution to the equation?The allocation of weights to the important variables that produce the calculation's optimum is referred to as a direct consequence.
The linear equations are given below.
−x + 4y = −9 ...1
y = −2x + 6 ...2
From equations 1 and 2, then we have
−x + 4(−2x + 6) = −9
−x − 8x + 24 = −9
−9x + 24 = −9
9x = 24 + 9
9x = 33
x = 11 / 3
Then the value of the variable 'y' is calculated as,
y = −2(11/3) + 6
y = −22/3 + 6
y = −4/3
The arrangement of the situation 4y − x + 9 = 0 and y = 6 − 2x will be (11/3, −4/3). Point (2, 3) isn't the arrangement of the framework.

The point (2, 3) does not satisfy either of the given equations, −x + 4y = −9 and y = −2x + 6. Therefore, it is not a solution to the system of equations.
Explanation:To determine if the point (2, 3) is a solution to the system of equations consisting of −x + 4y = −9 and y = −2x + 6, we need to check whether the point satisfies both equations.
For the first equation, substitute x with 2 and y with 3: −(2) + 4(3) = −9 to see if it results in a true statement.For the second equation, substitute x with 2: −2(2) + 6 = 3 to see if it equates to the y-value of 3.
Let's substitute the values into the first equation:
−(2) + 4(3) = −8 + 12 = 4, which does not equal −9. Therefore, the point does not satisfy the first equation.
For the second equation:
−2(2) + 6 = −4 + 6 = 2, which does not equal 3. Hence, the point does not satisfy the second equation either.
Since the point (2, 3) does not satisfy either equation, it is not a solution to the system of equations.

Graph this line using the slope and y-intercept Y=1/2x+9
Answer:
Step-by-step explanation:
I don't have a picture so I'll visually describe it. You start at the point (0,9) because 9 is the y intercept. Now that you have your first point, to get the next point, move up one and 2 to the right. Now, you're at the point (2,10). Continue going up one and 2 to the right until you get to the end of the graph. Then, go back to the point (0,9). This time, go the opposite way. Go one down, and two to the left. Now, you should be at the point (-2,8). Continue going down one, two left until once again, you run out of room on the graph. Then, use a ruler or freehand draw a line connecting your points. Add arrows on the ends on the line. Hope this helped!

congruent triangles, each has a height of
about 6 inches. What is the approximate
area of the hexagon?
Explain please!
Answer:
Approximately 252 inches squared.
Step-by-step explanation:
Answer:
126 in.^2
Step-by-step explanation:
The hexagon is divided into 6 congruent triangles. The area of the hexagon is 6 times the area of one of the triangles.
Now think of each triangle.
The side of the hexagon is the base of the triangle. The side of the hexagon has length 7 inches, so the base of the triangle has length 7 inches.
The height of the triangle is approximately 6 inches.
area of triangle = base * height/2
area of hexagon = 6 * area of triangle
area of hexagon = 6 * base * height/2
area of hexagon = 3 * base * height
area of hexagon = 3 * 7 in. * 6 in.
area of hexagon = 126 in.^2
What is the measure of arc EG?
The measure of arc EG = 16°.
Solution:
Given data:
m∠X = 47° and m(ar FH = 110°)
To find the measure of arc EG:
We know that,
Angle formed by two intersecting secants outside the circle is equal to half of the difference between the intercepted arcs.
[tex]$m \angle X=\frac{1}{2}({arc} \ FH-{arc} \ EG)[/tex]
[tex]$47^{\circ}=\frac{1}{2}\left(110^\circ- {arc} \ EG}\right)[/tex]
Multiply by 2 on both sides.
94° = 110° - arc EG
Subtract 110° from both sides.
-16° = -arc EG
Multiply -1 on both sides, we get
16° = arc EG
Switch the sides.
arc EG = 16°
The measure of arc EG = 16°.
A triangular banner has a base length of 48
inches. The banner has an area of 1,632 square
inches. What is the height of the banner?
Answer:68
Step-by-step explanation:
Area of triangle=1/2×base×height
1632=1/2×48×h
1632×2=48×h
3264=48×h
3264/48=h
68=h
Final answer:
To find the height of a triangle with an area of 1,632 square inches and a base of 48 inches, we use the formula A = (base × height) / 2. Solving for height gives us a result of 68 inches.
Explanation:
To calculate the height of a triangle when its area and base length are known, we use the formula for the area of a triangle: A = (base × height) / 2. Given that the area of the triangular banner is 1,632 square inches and the base length is 48 inches, we can set up the equation:
1,632 = (48 × height) / 2
Multiplying both sides of the equation by 2 to get rid of the denominator:
3,264 = 48 × height
Next, divide both sides by 48 to isolate the height:
height = 3,264 / 48
height = 68 inches
Therefore, the height of the triangular banner is 68 inches.

Answer:
The total area of the field is 7378.8 square meters.
The total area of the field is 8825.0448 square yards.
Step-by-step explanation:
Given : A soccer field (football pitch) has a length of 103.2 m and a width of 71.5 m.
To find : The total area of the field in square meters (m²) and convert this measurement to square yards (yd²) ?
Solution :
The length l=103.2 m
The width w=71.5 m
The area of the field is [tex]A=l\times w[/tex]
[tex]A=103.2\times 71.5[/tex]
[tex]A=7378.8\ m^2[/tex]
The total area of the field is 7378.8 square meters.
We know that,

[tex]7378.8\ m^2=7378.8\times 1.196\ yd^2[/tex]
[tex]7378.8\ m^2=8825.0448\ yd^2[/tex]
The total area of the field is 8825.0448 square yards.
The area of the soccer field is 7378.8 m^2 and 8822.6 square yards.
Explanation:The area of a rectangle (which is the shape of a soccer field) can be found by multiplying the length and the width. So, the area of the soccer field in square meters is 103.2 m (length) times 71.5 m (width), which equals 7378.8 m2.
To convert this area to square yards, you should know that 1 square meter is approximately equal to 1.19599 square yards. So, multiply our previous answer with this value. The area of the soccer field will be 7378.8 m2 times 1.19599 to get 8822.6 yd2.
