Answer: [tex]1\frac{16}{25}[/tex]
Step-by-step explanation:
1.64 is 1 64/100. Now to get the simplest form find a number you can divide both the numerator and the denominator by, like 4. Now you have 1 16/25. 16 and 25 do not have a common number you can divide both by so it is the simplest form.
A1 plumbing service charges $35 per hour plus a $25 travel charge for a service call. good guys plumbing repair charges $40 per hour for a service call with no travel charge. How long must a service call be for the two companies to charge the same amount
For given charges of plumbing service charges of two companies , the time of service two companies to charge the same amount is equal to 5 hours.
As given in the question,
Let 'h' hours be the time when service two companies to charge the same amount
A1 plumbing service company;
Charges $35 per hour plus a $25 travel charge for a service call
Equation:
y=25 + 35h
Good guys plumbing repair company :
Charges $40 per hour for a service call with no travel charge
Equation:
y=40h
Time when service two companies to charge same amount
25 +35h = 40h
⇒40h -35h=25
⇒5h=25
⇒h=25/5
=5hours
Therefore, for given charges of plumbing service charges of two companies , the time of service two companies to charge the same amount is equal to 5 hours.

Solve 757 ÷ 104 = ________. Use how the placement of the decimal point changes when divided by a power of 10 to help you.
It is important to note that 757 ÷ 104 using the placement of decimal point changes when divided by a power of 10 is not feasible. I believe you may be referring to 757 ÷ 10⁴ the answer therefore, is 0.0757. See explanation below.
How is the placement of decimal used to achieve the answer above?Suppose, as earlier indicated, the question is 757 ÷ 10⁴; that is
757 ÷ (10 x 10 x 10 x 10)
= 757 ÷ 10,000
Using the placement of decimal, we now by the number of zeros that the decimal point will move leftwards of 757 four times.
Note, that the decimal point is moving left because this is a division. In the case of a multiplication, the decimal point of a real number will move to the right.
Hence,
757 ÷ 10000
= 0.0757

Answer:
The height of the triangle is 3 inches.
Explanation:
Given:
[tex]\begin{gathered} \text{Base of the triangle}=3\frac{2}{5}\text{ inches} \\ \text{Area of the triangle}=5\frac{1}{10}\text{ inches} \end{gathered}[/tex]We change the mixed fractions to improper fractions below:
[tex]\begin{gathered} \text{Base of the triangle}=3\frac{2}{5}=\frac{(5\times3)+2}{5}=\frac{17}{5}\text{ inches} \\ \text{Area of the triangle}=5\frac{1}{10}=\frac{(10\times5)+1}{10}=\frac{51}{10}\text{ inches} \end{gathered}[/tex]We want to find the height of the triangle.
Recall that the area of a triangle is calculated using the formula below.
[tex]\text{Area}=\frac{1}{2}\times\text{Base}\times Height[/tex]Substitute the given values:
[tex]\frac{51}{10}=\frac{1}{2}\times\frac{17}{5}\times\text{Height}[/tex]Multiply the numerators and denominators on the right side of the equation.
[tex]\begin{gathered} \frac{51}{10}=\frac{1\times17}{2\times5}\times\text{Height} \\ \frac{51}{10}=\frac{17\times\text{Height}}{10} \end{gathered}[/tex]Multiply both sides by 10.
[tex]\begin{gathered} \frac{51}{10}\times10=\frac{17\times\text{Height}}{10}\times10 \\ \implies51=17\times\text{Height} \end{gathered}[/tex]To solve for the height, divide both sides by 17.
[tex]\begin{gathered} \frac{51}{17}=\frac{17\times\text{Height}}{17} \\ 3=\text{Height} \\ \text{Height = 3 inches} \end{gathered}[/tex]The height of the triangle is 3 inches.
scale factor and dilations
The scale factor here is 3 : 2.
What is meant by scale factor and dilations?The scale factor is defined as the difference between the new image's and the old image's sizes. A fixed point in the plane is the center of dilation. The definition of the dilation transformation depends on the scale factor and the center of dilation.
A stretched image results from a scale factor of higher than 1.
The image shrinks when the scale factor falls between 0 and 1.
The resulting image is consistent with the source image if the scale factor is 1.
As a result of the dilation modifications, the following characteristics of forms don't change:
The figure's angles are all identical.
The figure's midpoints on its sides and the midpoint of the dilated shape are both preserved.

Which is the graph of the function f(x) = x3 + x2 + x + 1?
Answer:
Step-by-step explanation:
Clues to recognize the graph:
-The graph will cross from the first quadrant into the third quadrant.
-The graphs of cubed equations are looking like an S shape.
-The graph must cross at y = 1 because when x is zero y is 1
If x=0 in our equation y= x^3 + x^2 + x + 1 will be y=1
-The graph must have a zero at x= -1 because if we rewrite the equation
y= x^3 + x^2 + x + 1 = (x+1)(x²+1) and here we see that one of the roots or zeros is (x+1) = 0, x= -1
