Suppose a college student pays $700 for tuition fees. However, she also has to pay $400 for her textbooks (ouch!). What percent of her total education costs does she pay for her books? Write your answer to the nearest tenth of a percent, but in decimal form.
Answers
400/1100=0.36363636...
The books cost about 36 percent of her education costs
The student spends approximately 40% of her total education costs on her books, represented as 0.4 in decimal form.
Explanation:The student's total education costs are the sum of the tuition fees ($700) and the cost of her books ($400). This comes to a total of $700 + $400 = $1100. The percent of the total education cost that is spent on books is then given by the cost of the books divided by the total cost, or $400 / $1100. When expressed as a decimal, this works out to be approximately 0.36 or 36%, but since we want to the nearest tenth of a percent in decimal form, it becomes 0.4 or 40% to the nearest tenth. Therefore, the student spends 40% of her total education costs on her books.

Christa went shopping for back-to-school clothes. Before the tax was added on, her total was $176. If the sales tax is 6%, what was the total amount she paid?
Answers
176 * 0.06= 10.56
$10.56 represents the number that needs to be added to get the total
176+10.56= 186.56
So Christ spent $186.56 on back to school clothes
Answer:
$176·1.06 = $186.56
Therefore, the total amount that Christa paid was $186.56.

An angle is 5 times the measure of its complement. find the measure of the larger angle
Answers
Answer:
75°
Step-by-step explanation:
The angle is our unknown, so we will call it x. If x is the angle, then its complement is 90 - x (complementary angles add up to 90). The word "is" means "equals", and "5 times" is multiplying the complementary by 5:
x = 5(90 - x) so
x = 450 - 5x
Combine like terms to get
6x = 450 so
x = 75
The other angle, the complement to that angle, is 90 - 75 = 15
The larger angle is 75°

Find the equation perpendicular to the line y=−3x+5 that passes through point (2, 6).
Answers
Hey there! :)
Perpendicular to y = -3x + 5 ; passes through (2, 6).
Our slope is -3. We know this because it is in the "m" position from slope-intercept form. However, since our equation we're looking for is perpendicular to our given one, we must find the negative reciprocal of -3.
A negative reciprocal is simply a number that is flipped and either given a negative or gets a negative removed.
So the negative reciprocal of -3 is 1/3. This means that our new slope is 1/3.
Now, using point-slope form ( y-y₁=m(x-x₁) ), our new slope (1/3) & (2, 6) , let's find our new equation!
y-y₁=m(x-x₁) y - (6) = 1/3(x - 2)
Simplify.
y - 6 = 1/3x - 2/3

Angle bisectors of the angles ∠A and ∠B of a triangle ∆ABC intersect each other at point M. Find m∠AMB, if m∠A = 58°, m∠B = 96°.
Answers
measure angle B is 96 degrees, this means that the angle bisector divides the angle into two equal angles each of measure 96/2 = 48 degrees
In triangle AMB, we know that the sum of all measure of a triangle is 180 degrees and we have measure angle MAB = 29 degrees and measure angle MBA = 48 degrees
Therefore,
measure angle AMB = 180 - (29+48) = 103 degrees
Answer:
103 degrees
Step-by-step explanation:
Bisectors means you make a line in the middle splitting the angle in half. So you divide A by 2 to get 29 and B to get 48. Then you add them to get 77. And now you only need point m's angle. 180-77 is 103 so the answer they are looking for is 103.

The numerical expression 4[(6 - 1) + 3(5 - 2)] evaluates step-by-step following the order of operations. Operations within the parentheses are performed first, followed by multiplication, resulting in a final answer of 56
The student's question involves evaluating a numerical expression, which is a concept in mathematics. We have the expression 4[(6 - 1) + 3(5 - 2)] and want to calculate its value step by step following the order of operations:
First, perform the operations inside the parentheses: (6 - 1) = 5 and (5 - 2) = 3.Next, multiply by 3 within the parentheses: 3(5 - 2) becomes 3 * 3 = 9.Now, add the results within the square brackets: 5 + 9 = 14.Finally, multiply the result by 4: 4 * 14 = 56.Hence, the correct answer to the expression is 56

A worker currently receives a yearly salary of $20,000.

Answers
do the same for 4% and 6%
And round to the nearest dollar
Hey!
Hope this helps...
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
Because we are finding DOLLAR amounts, and not a total, we are simply going to do this:
Salary * (percent /100) = $Value
20,000 * 3% [or 0.03] = $600
20,000 * 4% [or 0.04] = $800
20,000 * 6% [or 0.06] = $1,200
Now to find his new salary if he were to get a raise, we will add the individual amounts to 20,000 is he were to only get a SINGLE percent raise increase...
If his salary (currently) is $20,000 and gets a 3% raise, his new salary is:
$20,600
If his salary (currently) is $20,000 and gets a 4% raise, his new salary is:
$20,800
If his salary (currently) is $20,000 and gets a 6% raise, his new salary is:
$21,200
If he were to get all THREE raises at the same time (per say) [or one after the other going off of a $20,000 salary], his new salary is:

You can find the corresponding parts of two congruent triangles by aligning them perfectly on top of each other.
What are Congruent Triangles?Transformations change the size or position of shapes. Congruent shapes are identical, but may be reflected, rotated or translated. Scale factors can increase or decrease the size of a shape. Congruent Triangles simply mean the triangles that possess the same size and shape
The three sides are equal (SSS: side, side, side)
Two angles are the same and a corresponding side is the same (ASA: angle, side, angle)
Two sides are equal and the angle between the two sides is equal (SAS: side, angle, side)
A right angle, the hypotenuse and a corresponding side are equal (RHS, right angle, hypotenuse, side)
