Answer:
38.95
Step-by-step explanation:
[tex] \frac{19}{100} \times 205 = 38.95[/tex]
The 19 percentage of the number 205 is 38.95
What is Percentage?A percentage is a number or ratio expressed as a fraction of 100. It is often denoted using the percent sign, %
The difference between an exact value and an approximation to it is the approximation error in a data value. Either an absolute error or a relative error might be used to describe this error.
Percentage change is the difference between the measured value and the true value , as a percentage of the true value
Percentage change =( (| Measured Value - True Value |) / True Value ) x 100
Given data ,
Let the percentage value of the number be represented as A
Now , let the number be n = 205
Let the percentage be = 19 %
So , the value of A = n ( 19 % )
On simplifying , we get
A = 205 ( 19/100 )
A = 38.95
Therefore , the value of A is 38.95
Hence , the percentage value is 38.95

The measure of angle U in the trapezoid RSTU with congruent diagonals and angle S measuring 112 degrees is 68 degrees, using the properties of an isosceles trapezoid.
To find the measure of in the trapezoid RSTU, with diagonals congruent and the measure of angle S being 112 degrees, we need to use the properties of a trapezoid and the fact that the diagonals are congruent. In an isosceles trapezoid, the base angles are congruent, meaning angles S and U are congruent because diagonals are congruent. Since the sum of angles in a quadrilateral is 360 degrees, we can set up an equation: 2(112) + 2(angle U) = 360.
Solving for angle U, we get:
224 + 2(angle U) = 3602(angle U) = 136angle U = 68 degreesHence, the measure of angle U in the trapezoid RSTU is 68 degrees.

Write a polynomial f (x) that satisfies the given conditions. Polynomial of lowest degree with zeros of -3 (multiplicity 3) 2(multiplicity 1)and with f(0)=270 .
Final answer:
To write a polynomial f(x) with specified zeros and a value for f(0), we first express the polynomial in its factored form, then solve for the coefficient using the given f(0) value. The resulting polynomial is f(x) = -5(x + 3)^3(x - 2).
Explanation:
To write a polynomial f(x) of the lowest degree with zeros of -3 (multiplicity 3) and 2 (multiplicity 1), we use the fact that zero of multiplicity m means the factor corresponding to that zero will appear m times in the factored form of the polynomial. Given these zeros, the polynomial in its factored form is:
f(x) = a(x + 3)^3(x - 2)
We are also given that f(0) = 270. We can use this information to find the value of a:
f(0) = a(0 + 3)^3(0 - 2) = 270
a = 270 / [(-2)(3)^3]
a = 270 / (-54)
a = -5
Now we can write the polynomial with the determined value of a:
f(x) = -5(x + 3)^3(x - 2)
This is the polynomial of the lowest degree that meets the given conditions.
A trapezoid with bases of 18 feet and 12 feet, height of 4 feet, and side length of 5 feet. What statements are true? Check all that apply. The height of the new trapezoid will be 1 ft. The height of the new trapezoid will be 16 ft. The area of the new trapezoid is One-fourth times the area of the original trapezoid. The area of the new trapezoid is StartFraction 1 Over 16 EndFraction times the area of the original trapezoid. The area of the new trapezoid is 4 times the area of the original trapezoid.
Answer:
A and D
Step-by-step explanation:
Got it right :)
Final answer:
The true statement about the new trapezoid is that the area of the new trapezoid is \(1/16\) times the area of the original trapezoid, assuming that all dimensions are scaled down by the same factor.
Explanation:
The area of a trapezoid is given by the formula: [tex]Area = \((base_1 + base_2) / 2\) * height[/tex]. For the original trapezoid with bases of 18 feet and 12 feet and a height of 4 feet, the area is [tex]\((18 + 12) / 2\) * 4 = 60[/tex] square feet. If the dimensions of the trapezoid are scaled down or up, the new height and area can be determined by using the same proportionality principle that applies to triangles. If the height is reduced by a factor of 4, which means the new height is 1 foot, then the area will also be reduced by the same factor squared (since area is a two-dimensional measure). Therefore, the new area will be 1/16 times the original area, which equals 60 / 16 = 3.75 square feet.
Rose lives 3/4 of a mile from her cousin. One day she rode her bike to her cousin's house. When she got 2/5 of the way there, her bike chain broke and she had to walk the rest of the way. What part of a mile did Rose go on her bike before it broke?
Answer: 3/10 of a mile
Step-by-step explanation:
Hi, to answer this question we simply have to multiply the 2/5 of the way that she travelled on her bike before it broke by the total distance (3/4 of a mile)
2/5 x 3/4 = 3/10 of a mile
She travelled 3/10 of a mile on her bike before it broke
Feel free to ask for more if needed or if you did not understand something.
Rose traveled [tex]\( \frac{3}{10} \)[/tex] of a mile on her bike before it broke, found by multiplying 2/5 by 3/4. Equation: Distance on bike = (2/5) × (3/4).
To find out what fraction of a mile Rose traveled on her bike before it broke, we need to find 2/5 of 3/4 mile.
[tex]\[ \text{Distance traveled on bike} = \left(\frac{2}{5}\right) \times \left(\frac{3}{4}\right) \][/tex]
[tex]\[ = \frac{2}{5} \times \frac{3}{4} \][/tex]
[tex]\[ = \frac{2 \times 3}{5 \times 4} \][/tex]
[tex]\[ = \frac{6}{20} \][/tex]
[tex]\[ = \frac{3}{10} \][/tex]
So, Rose traveled [tex]\( \frac{3}{10} \)[/tex] of a mile on her bike before it broke.
The equation for this would be:
[tex]\[ \text{Distance on bike} = \left(\frac{2}{5}\right) \times \left(\frac{3}{4}\right) \][/tex]
Complete Question:
Rose lives 3/4 of a mile from her cousin. One day she rode her bike to her cousin's house. When she got 2/5 of the way there, her bike chain broke and she had to walk the rest of the way.

If a variable does not have a coefficient then it is either a 1 or a -1. true or false
Answer:
True
Step-by-step explanation:
If the coefficient is -1 then the variable will have a negative sign in front of it.
Example: (-x)
If the coefficient is 1 then the variable will stand alone.
Example: (x)
Answer:
True
Step-by-step explanation:
An example of a variable "without" a coefficient is x or -x. There is no number beside x, meaning there is no visible coefficient. And when there is no visible, coefficient, the variable is multiplied by 1 or -1 (the negative sign determines whether the variable is negative or not).

therefore
[tex]x=\£4\\y=\£14[/tex]
Part 2) For 6 metres of fabric
To find out the costs multiply the ratio by the fraction 6/6
so
[tex](\frac{6}{6})\frac{2}{7}=\frac{12}{42}[/tex]
therefore
[tex]x=\£12\\y=\£42[/tex]
Part 3) For 8 metres of fabric
To find out the costs multiply the ratio by the fraction 8/8
so
[tex](\frac{8}{8})\frac{2}{7}=\frac{16}{56}[/tex]
therefore
[tex]x=\£16\\y=\£56[/tex]
Part 4) For 9 metres of fabric
To find out the costs multiply the ratio by the fraction 9/9
so
[tex](\frac{9}{9})\frac{2}{7}=\frac{18}{63}[/tex]
therefore
[tex]x=\£18\\y=\£63[/tex]
