Answer:
Here we want to calculate the 25% of $140.
Well, first we assume that:
$140 = 100%.
Now, assuming that, we can write the equation:
X = 25%
Where X is the 25% of $140.
Then we have the equations:
$140 = 100%
X = 25%
Let's take the quotient between these equations:
$140/X = (100%/25%)
Now let's solve this for X:
X = (25%/100%)*$140 = 0.25*$140 = $35
Then the tip will be of $35
35
you have to split 140 into 4 parts which is division
your expression would be 140 divided by 4
Which best describes the relationship between the 125° angle and angle A?
They are same side interior angles. Angle A measures 55°.
They are alternate interior angles. Angle A measures 125°.
They are vertical angles. Angle A measures 125°.
They are corresponding angles. Angle A measures 55°.
Answer:
A.

Megan's bank account is charged $9.95 per month for an online newspaper subscription how can you represent a change in her account balance after three months of charges
Answer:
T = C - (9.95 * 3)
Step-by-step explanation:
The account balance total can be calculated with the following equation where the variable T represents the final balance while the variable C represents her current balance before the three months...
T = C - (9.95 * 3)
The monthly charge is multiplied by the three months that Megan will be charged and then discounted from her current balance in order to give the new Total Balance after paying the subscription for the three months.
I need help with another one! Thankyou guys this means alot to me
Answer:
9.5 = y
Step-by-step explanation:
You have to use the cosine function equation.
cos(38) = [tex]\frac{y}{12}[/tex]
Multiply 12 on both sides.
12cos(38) = y
Solve.
9.46 = y
Answer:
9.5
Step-by-step explanation:
y is the adjacent side of the given 38 degree angle. You are given the hypotenuse of right angle triangle. So the trig function that you need to use is the Cosine
Cos(38) = y / 12
multiply both sides by 12
12*cos(38) = 12*y/12
12*cos(38) = y
12*0.7880= y
y =9.456

(HELP PLEASE!! answer all the questions) Mr. Smith decorates his U.S. History classroom by putting up pictures of the presidents. The wall is 9.75 feet long. In the center, there is a window that is 5 34feet long.
Each president's picture is 6 inches wide.
If the pictures are placed side by side on either side of the window, how many pictures can he fit on this wall?
Answer the questions to solve this problem.
1. How many feet long is the space Mr. Thuman wants to fill with pictures? Explain how you know.
Write your answer in the space below.
2. Convert this length to inches. (There are 12 inches in 1 foot)
Write your answer in the space below.
3. How many pictures will Mr. Thuman use? Explain how you found your answer.
Write your answer in the space below.
4. How would your answer change if the pictures were 10 inches wide? Explain.
Write your answer in the space below.
9514 1404 393
Answer:
4.00 feet48 inches8 pictures4 picturesStep-by-step explanation:
1. The available wall space is the difference between the length of the wall and the length of the window:
9.75 ft - 5.75 ft = 4.00 feet
__
2. At 12 inches per foot, this is ...
(4 ft)(12 in/ft) = 48 in
__
3. If the pictures are 6 inches wide, Mr. Smith can use ...
(48 in)/(6 in/picture) = 8 pictures
__
4. If the pictures are 10 inches wide, Mr. Smith can use ...
(48 in)/(10 in/picture) = 4.8 pictures
There is room for 4 pictures. Space for a fraction of a picture is not useful. This number is even, so 4/2 = 2 pictures can be placed on either side of the window.
What is the solution to −(6m + 8) = 4(17 − m)?
Answer:
m= -38
Step-by-step explanation:
-(6m+8)=4(17-m)
-6m-8=68-4m
-6m+4m-8=68
-2m-8+8=68+8
-2m=76
-2m/-2=76/-2
m= -38

Answer:
C. x=2.5, DC=7.5, EC=15
Step-by-step explanation:
since the triangles have congruent angles, the sides have a relationship too. Basically, the ratio between the triangle is 4:10 because those sides math up. So, that also means it is 2:5. Therefore, BC:EC=6:15. 15-12.5=2.5, so x=2.5.
Now you can just do 2.5+5=7.5 so DC=7.5
Below are two parallel lines with a third line intersecting them
Answer:
Z is 66. If you want an explanation, I could give it to you, FYI.
Answer:
x=66°
Step-by-step explanation:
Solve for x:
If the two vertical lines are parallel, then the given angles are same side interior angles that are supplementary angles. This means that their values add up to 180°:
∠1+∠2=180°
Substitute known values:
[tex]x+114=180[/tex]
Subtract 114 from both sides to isolate x:
[tex]x+114-114=180-114\\\\x=66[/tex]
The value of x is 66°.
