40°, 50° and 90°
the sum of the angles in a triangle = 180°
sum the parts of the ratio : 4 + 5 + 9 = 18 parts
divide 180 by 18 to obtain 1 part
[tex]\frac{180}{18}[/tex] = 10° ← 1 part

842.72+412.38+1/8+1/2=
the answer will be 1255.725
For this case, we have the following expression:
[tex]x = 842.72+412.38+\frac{1}{8} +\frac{1}{2}[/tex]
We want to find the value of x
Simplifying we have to:
[tex]\frac{1}{8} = 0.125\\\\\frac{1}{2} = 0.5\\[/tex]
Therefore:
[tex]x = 842.72 + 412.38 + 0.125 + 0.5\\\\x = 1255.725\\[/tex]
Answer:
The value of the variable x is given by:

shen baked b cookies. his family ate 11 of them. using b, write an expression for the number of cookies that remained.
Step-by-step explanation:
So, lets write out the equation you have right now.
B - 11 = ?
You can have B be whatever you want. It must be higher than 11 (unless your teacher or whoever your guardian is allows negative numbers). In this case, I will use 15.
B = 15
15 - 11 = ?

What is the Recipical of 8/19?
The question states that we are looking for the reciprocal of 8/19.
Recall what a reciprocal is. A reciprocal, when looking at a number, is what is multiplied with it for it to equal 0. It is commonly regarded as just the fraction flipped. (For example, the reciprocal of 1/2 would be 2, or 2/1. 2 * 1/2 = 1)
But why does flipping a fraction work?This goes back to the simplifying, when multiplying two fractions together.
If you were to multiply two fractions, say [tex]\frac{5}{4}[/tex] and [tex] \frac{4}{5}[/tex], you could look at the numerator of one and the denominator of another, and cancel them out. In this case, the numerator of one is 5, and the other is also 5. Cancelling those out makes both one. If you cancel out 4 and 4 too, you get 1/1 * 1/1, or just 1.
We could go on asking why these methods work forever. Why does cancelling out a numerator and a denominator of separate fractions work? (A simple explanation is when the separate fractions are multiplied together, you could divide both sides by the factor which was originally used to cancel out with, which is what was stated above but simpler.)
Now, we can figure out the answer.Since we know the reciprocal is just the flipped form of the fraction, we can simply flip 8/19 to get our answer.
8/19 flipped is 19/8, which is our answer.
Hope this helped!Drag the correct steps into order to solve the equation -3x – 6 = 18 for x.
The solution to the linear equation -3x - 6 = 18 is x = - 8
What is the solution of the equation?The solution of the linear equation is calculated as follows;
The given linear equation;
-3x - 6 = 18
Move the constant term to the other side of the equation.
-3x - 6 + 6 = 18 + 6
-3x = 24
Divide both sides of the equation by the coefficient of x (-3) to isolate x.
(-3x) / (-3) = 24 / (-3)
x = -8
Thus, the solution to the linear equation -3x - 6 = 18 is x = - 8

Final answer:
To multiply 14 by 25, you multiply each digit of 25 by 14 individually and then sum the results, yielding a product of 350.
Explanation:
The student has asked to multiply 14 by 25 and express the answer in simplest form. Multiplication is a basic arithmetic operation, and it is a straightforward process. To multiply 14 by 25, you can use the following steps:
Multiply the ones digit of the second number by the first number: 5 x 14 = 70.
Multiply the tens digit of the second number by the first number: 2 x 14 = 28. Remember that since this 2 represents 20 in the number 25, the result (28) will actually represent 280 when you include it in the final answer.
Add the results from steps 1 and 2: 70 + 280 = 350.
Thus, the product of 14 and 25 is 350.
Marcus finds that (3x^2-2y^2+5x)+(4x^2+12y^2-7x)=7x^2-10y-2x. What error did Marcus make?
(3x²-2y²+5x)+(4x²+12y²-7x)
This is all about combining like terms.
(7x²+10y²-2x) is what I got.
(7x-10y-2x) is what Marcus got.
Marcus didn't add the squared symbol for 10y and he added a negative sign for 10y. He did -10y but it is +10y² because -2y²+12y²=10y². So, his problem is that Marcus didn't add right.
Hope this helps.

Fifteen percent of an employee’s taxable income is collected each paycheck. Before taxes are removed from each paycheck, $350 of tax-exempt expenses is taken out. If the variable x represents the employee’s pay before tax-exempt expenses and taxes are removed, which expression represents the employee’s take-home pay after these deductions?
Answer:
0.85(x - 350)
Step-by-step explanation:
Here "x" represents the pay before tax.
Take exempted amount = 350.
The taxable amount = x - 350.
The tax rate = 15% = 15/100 = 0.15
Take home pay after the tax deduction = Taxable amount - tax
= (x - 350) - 0.15(x - 350)
Now we have to simplify this.
= (x - 350)(1 - 0.15)
= (x - 350)(0.85)
The employee’s take-home pay after these deductions= $0.85(x - 350).
Thank you.

Jadyn prepares a bag of candy before a road trip. The bag contains individual pieces of Skittles, M&Ms, Life Savers and Sour Patch Kids. Of the candy, 1/2 are Skittles, 1/4 of the remaining pieces are M&Ms and 3/4 of the rest are Life Savers. The remaining pieces are Sour Patch Kids. What percent of the total pieces of candy are Sour Patch Kids?
Given condition is- The bag contains individual pieces of Skittles, M&Ms, Life Savers and Sour Patch Kids.
Let the total number of candies in the bag be = x
Then, Skittles are [tex]\frac{1x}{2}[/tex]
Candies left = [tex]x-\frac{x}{2}[/tex] = [tex]\frac{x}{2}[/tex]
M&Ms are = [tex]\frac{1x}{8}[/tex]
Now remaining candies are= [tex]\frac{3x}{8}[/tex]
Now Life savers are = [tex]\frac{9x}{32}[/tex]
Now adding all these 3 candies
[tex]\frac{x}{2}+ \frac{x}{8}+\frac{9x}{32}[/tex]
=[tex]\frac{29x}{32}[/tex]
Now the remaining candies sour patch will be =
[tex]x-\frac{29x}{32} =\frac{3x}{32}[/tex]
Hence, sour patch kids are [tex]\frac{3}{32}[/tex]

What is Statistics?Statistics is the discipline that concerns the collection, organization, analysis, interpretation, and presentation of data.
Lets compare the dot plots of the two brands.
In Brand A,
The number of candy pieces per bag ranges from 52 to 62, and the dots are relatively evenly spread out across this range.
In Brand B,
the number of candy pieces per bag ranges from 44 to 69, and the dots are more spread out, with a larger range of values.
As we observe the majority of the dots are clustered around 52, 55, 62, 65, and 67, indicating that these values are more common in Brand B than in Brand A.
Brand B has more dots in total than Brand A, suggesting that Brand B generally has more candy pieces per bag than Brand A..
Hence, the number of candies in the bags from Brand B is greater and less consistent than the number of candies in the bags from Brand A is valid statement.

what is the y intercept of -3x-5y=60
Answer: y-intercept = -12
Step-by-step explanation:
[tex]-3x = 60+5y[/tex] Add [tex]5y[/tex] on both side
[tex]-3x-60 = 5y[/tex] Subtract [tex]60[/tex] on both sides
[tex]-\frac{3}{5}x-12=y[/tex] Divide 5 on both sides
The y-intercept of the line -3x - 5y = 60 is equal to -12.
What is the slope-intercept form?In Mathematics and Geometry, the slope-intercept form of the equation of a straight line is given by this mathematical equation;

Swimming pool is generally build as a cuboid.
Volume of cuboid refers to the measurement of the space in the cuboid. It is the product of length, breadth and height of the cuboid.
Therefore the formula to calculate volume of cuboid will be:
[tex]\rm Volume\:of\:cuboid = \rm length\times breadth \times height[/tex]
The volume of the pool will be [tex]\rm 3a^8 b^4[/tex].
To reach the above answer, following calculations are required:
Given:
Dimensions of the pool:
[tex]\begin{aligned} \rm Length &= 3a^6\\\rm Breadth &= a^2\\\rm Height &= b^4\end[/tex]
Therefore, volume of pool will be as follows:
[tex]\begin{aligned} \rm Volume\:of\:cuboid &= \rm length\times breadth \times height\\&= 3a^6 \times a^2 \times b^4 \\&= 3a^{6+2}b^4\\&= 3a^8b^4 \end[/tex]
