A carpenter is making a brace for a chair. To do so she intersects two pieces of wood to make two sets of vertical angles. The ostuse angles formed are each 145 . What is the measurement of each acute angle formed

Answers

Answer 1
In this question, there are two pieces of wood that crossed together. It will form 2 line that cut each other in the middle, looked like X.
In this case, the angles will be divided into 4 and two of the adjacent angel will result in 180° if you add them. Then the answer to this question would be: 180°-145°= 35°
The acute angle formed will be 35°

Let’s assume that one drop is equal to 50 µl. a total of 2366 drops will fill how many tablespoons?

Answers

First, we have to set the volume in 1 tablespoon. It actually depends on the country you're living. In USA, 1 tablespoon is approximately 14.8 ml. In microliters, that is equal to 14,800 μL. Thus,

Volume of the liquid = 50 μL/drop * 2366 drops = 118,300 μL
Therefore, that is equivalent to
Number of tablespoons = 118,300 μL/14,800 μL = 7.99924 or approximately 8 tablespoons

Write the equation in standard form using integers.
y=4x+9

Answers

y=4x+9 Start with the given equation

1y-4x=4x+9-4x Subtract 4x from both sides

-4x+1y=9 Simplify

-1*(-4x+1y)= -1 *(9)  Multiply both sides by -1 to make the A coefficient positive (note: this step may be optional; it will depend on your teacher and/or textbook)

4x-1y=-9 Distribute and simplify

The original equation y=4x+9 (slope-intercept form) is equivalent to 4x-1y=-9 (standard form where A > 0)

The equation 4x-1y=-9 is in the form Ax+By=C where A=4, B=-1 and C=-9
Final answer:

To convert the equation y = 4x + 9 to standard form, you subtract 4x from both sides to get -4x + y = 9, and then multiply by -1 to obtain 4x - y = -9, which is in the standard form with A, B, and C as integers.

Explanation:

To write the equation y = 4x + 9 in standard form using integers, we need to rearrange the equation so that it has the form Ax + By = C, where A, B, and C are integers, and A should be non-negative. Let's perform the transformation step by step:

Start with the given equation: y = 4x + 9.Subtract 4x from both sides of the equation to move the term with the variable x to the left side: -4x + y = 9.To ensure that the coefficient for x is non-negative, we can multiply the entire equation by -1 to get: 4x - y = -9, which is now in standard form with A = 4, B = -1, and C = -9.

In the process of constructing a table or plotting points, you would select values for x, calculate the corresponding y values, and then plot these values on a graph to visualize the line as described in Table A1 and Figure A1. Additionally, understanding that equations like 7y = 6x + 8, 4y = 8, and y + 7 = 3x are all linear equations, and understanding the relationship between independent and dependent variables, such as the year and the number of flu cases, is important in the context of mathematics and linear equations.

2/9 of the people on the restaurant are adults. If there are 95 more children than adults, how many children are there in the restaurant? Please give a simple explanation, with why you did each, Thanks!

Answers


let's call the children "c" and the adults "a"

the total # of people in the restaurant = c+a
so 2/9 of (c+a) = a

therefore 2/9c + 2/9a = a
and a + 95 = c since there are 95 MORE children.

Let's substitute a+95 for c in the equation 2/9(c+a) = a
this gives us 2/9(a+95 + a) = a
then 2/9 a + 2/9(95) + 2/9(a) = a
so 4/9a +190/9 = a
and 190/9 = 5/9 a
so 190 must = 5a
finally a = 38 so c must = 38 + 95 = 133 there are 133 children

4226 times .065=274.69

answer: $274.69 is Sam's commission

The commission of Sam Taylor as an advertising agency will be $274.69.

What is the percentage?

The quantity of anything is stated as though it were a fraction of a hundred. A quarter of 100 can be used to express the ratio. Per 100 is what the term percent signifies. The symbol ‘%’ is used to symbolize it.

The percentage is given as,

Percentage (P) = [Initial value - Final value] / Initial value x 100

Sam Taylor earns a 6 1/2% commission on sales of $4,226 as an advertising agent.

Then the commission of Sam Taylor as an advertising agency will be

P = (6 1/2%) x $4,226

P = 6.5% x $4,226

P = 0.065 x $4,226

P = $274.69

The commission of Sam Taylor as an advertising agency will be $274.69.

The line 3x+4y=24 cuts the x-axis at point A and the y-axis at B. Find
The coordinate of A and B
The length of AB
Point C is on the line such that C is equidistant from x and y-axis.find coordinate of C.

Answers

if line 3x + 4y = 24 cuts the x axis at point A, then point A is ur x intercept of line 3x + 4y = 24. To find the x int, sub in 0 for y and solve for x.
3x + 4y = 24
3x + 4(0) = 24
3x = 24
x = 24/3
x = 8....so point A is (8,0) <===

if line 3x + 4y = 24 cuts the y axis at point B, the point B is the y int. of 3x + 4y = 24. To find the y int, sub in 0 for x and solve for y
3x + 4y = 24
3(0) + 4y = 24
4y = 24
y = 24/4
y = 6......so point B is  (0,6) <===

if point C is equidistant from point A and point B, then it is the midpoint.
midpoint formula : (x1 + x2) / 2, (y1 + y2) / 2
(8,0)....x1 = 8 and y1 = 0
(0,6)...x2 = 0 and y2 = 6
time to sub and solve
m = (8 + 0)/2 , (0 + 6)/2
m = (8/2),(6/2)
m = (4,3) <=== this is point C
Final answer:

The coordinates of A and B are (8,0) and (0,6) respectively. The length of AB is 10 units. The coordinates of point C, which is equidistant from both axes, are (3,3).

Explanation:

To find the coordinates of points A and B, you should find the points where the line intersects the x and y-axes. For the x-axis (y=0), the equation 3x + 4(0) = 24 simplifies to 3x = 24, or x = 8. Therefore, the coordinates of A are (8,0). Similarly, for the y-axis (x=0), the equation 3(0) + 4y = 24 simplifies to 4y = 24, or y = 6. Therefore, the coordinates of B are (0,6).

To find the length of AB, we use the distance formula, √[(x2−x1)²+(y2−y1)²], which results in √[(0-8)²+(6-0)²] = √[64+36] = √100 = 10.

For point C to be equidistant from the x-axis and the y-axis, its coordinates must be the same. Substituting y=x into the equation of the line gives 3x + 4x = 24, or x=3. So the coordinates of C are (3,3).

If 3x - 1 = 11, what is the value of x2 + x?

Answers

Okay. 3x - 1 is 11. Add 1 to both sides and you'll get 3x = 12. Divide both sides by 3, and you'll get x = 4. In this case, the problem will be written out as 4 * 2 + 4. Do order of operations. For this problem, we multiply first. 4 * 2 is 8. Next, we add. 8 + 4 = 12. The value of x2 + x is 12.

The value of x² + x will be 20 when 3x - 1 = 11 .

Given, equation : 3x - 1 = 11

Firstly find the value of x from the equation .

Equation : 3x - 1 = 11

3x = 11 + 1

Twice the difference of a number and 5 is 2.
Use the variable W for the unknown number

Answers

Hey there!

The difference of a number, w, and 5 will be represented by (w – 5). Twice this would simply multiply this expression by 2, making it 2(w – 5). Finally, just set this expression equal to 2. Your equation is 2(w – 5) = 2. 

To solve this, expand the two to the terms in parentheses. Then, solve the rest of the way as you would normally, using addition, subtraction, multiplication, or division to cancel out and move around terms. Remember, what you do on one side must be done to the other!

2(w – 5) = 2
(2*w – 2*5) = 2
(2w – 10) + 10 = (2) + 10
(2w) ÷ 2 = (12) ÷ 2
w = 6

Hope this helped you out! :-)
Final answer:

By converting the verbal statement into an algebraic equation, we establish that the variable W, which represents the unknown number, is 6.

Explanation:

The question involves an algebraic expression, and it can be solved by first translating the verbal statement into an equation. Here, we're told that twice the difference of a number and 5 is 2, with the variable W representing the unknown number. The equation would therefore look like this: 2(W - 5) = 2.

To isolate W, next you divide each side by 2 yielding: W - 5 = 1.

Finally, to get W on its own, simply add 5 to both sides of the equation to get: W = 1 + 5, so W = 6.

angle ABE is equivalent to the whole angle, and it measures 2b. 
while the angle ABF is only a portion of angle ABE, and it measure 7b - 24. 

since we know the measure of the whole angle and a part of the angle, we can then subtract to find the left over angle (angle EBF), so

Angle EBF = Angle ABE - Angle ABF 

Angle EBF = 2b – (7b – 24)
