Answer:
It will take [tex]\frac{19}{101}[/tex] hour.
Step-by-step explanation:
The rule of the distance is:
Distance = speed × time
∵ An object is traveling at a steady speed of [tex]10\frac{1}{10}[/tex] km/h
∴ The speed = [tex]10\frac{1}{10}[/tex] km/h
∵ The object will travel [tex]1\frac{9}{10}[/tex] km
∴ The distance = [tex]1\frac{9}{10}[/tex] km
→ We need to find how long will it take it to travel this distance
→ Substitute the values of distance and speed in the rule above
∵ [tex]1\frac{9}{10}[/tex] = [tex]10\frac{1}{10}[/tex] × time
→ To find the time divide both sides by [tex]10\frac{1}{10}[/tex]
∴ The time = [tex]1\frac{9}{10}[/tex] ÷ [tex]10\frac{1}{10}[/tex]
→ Change the mixed numbers to an improper fraction
∵ [tex]1\frac{9}{10}[/tex] = [tex]\frac{(1)(10)+9}{10}=\frac{19}{10}[/tex]
∵ [tex]10\frac{1}{10}=\frac{(10)(10)+1}{10}=\frac{101}{10}[/tex]
∴ The time = [tex]\frac{19}{10}[/tex] ÷ [tex]\frac{101}{10}[/tex]
- Reverse the fraction after the division sign, then change ÷ to ×
∴ The time = [tex]\frac{19}{10}[/tex] × [tex]\frac{10}{101}[/tex]
→ 10 up will cancel 10 down
∴ The time = [tex]\frac{19}{101}[/tex] h
It will take [tex]\frac{19}{101}[/tex] hour.
An electrician charges a base fee of $60 plus $50 for each hour of work. The minimum the electrician
charges is $160. Create a table that shows the amount the electrician charges for 1, 2, 3, and 4 hours of
work. Determine the domain and range of the relation in context and explain whether or not this
represents a function.

The electrician charges $12.50 per hour, or $50 for 4 hours.
This is not a function for the fact that 1, 2, 3, and 4 all go to the same value.

Solve for b:
10abc - 2d = 3d
Answer:
b = d/(2ac)
Step-by-step explanation:
10abc - 2d = 3d
Add 2d to each side
10abc - 2d+2d = 3d+2d
10 abc = 5d
Divide each side by 10ac
10 abc/ (10ac) = 5d/10ac
b = d/(2ac)

Step-by-step explanation:
Kenny had a total of 140 minutes to read, do homework, and play video games.
He spent x minutes reading.
He spent 2(x+5) minutes doing homework
He spent 25 minutes playing video games
How many minutes did Kenny spend reading
Help fast Please
Answer: 35minutes
Step-by-step explanation:
Minutes spent reading = x
Minutes spent doing homework =2(x+5) = 2x + 10
Minutes spent playing video games = 25minutes
Total minutes used = 140 minutes
x + 2x + 10 + 25 = 140
3x + 35 = 140
3x = 140 - 35
3x = 105
x = 105/3
x = 35 minutes

Which expression is equivalent to 32−−√−3x2–√+38–√?
Answer:
8
Step-by-step explanation:
The indices question is not properly written. Find the correct expression in the attachment
[tex]-32^{\frac{3}{5} }[/tex] [tex]= (\sqrt[5]{-32})^3[/tex]
for [tex]\sqrt[5]{-32}[/tex]
we need a value to multiply 5 times that will give us -32;
[tex]\sqrt[5]{-32} = -2[/tex]
substitute the answer in the original expression
[tex]= (\sqrt[5]{-32})^3\\= 2^3[/tex]
Evaluate the resulting indices
[tex]2^3 = 8\\[/tex]
Hence the expression [tex]-32^{\frac{3}{5} }[/tex] is equivalent to 8

y=x^2+9x+3 write graph form
how do you differentiate linear equation from those equatipn which are not linear?
Answer:
the x
Step-by-step explanation:
Looking at the x in an equation can reveal its shape. A linear graph can look like y=x, y=mx, y=mx+b (m being any number).
When you look at graphs that aren't linear, the x doesn't stand alone in the equation.
Parabolas have a y=x^2 equation. Cubic graphs are y=x^3. They have something attached to the x.
To see all the different kinds of equations and what their graphs look like you can search up "parent functions" and all the basic formulas show up.
Complete the statements below that show y = x2 + 2x - 1 being converted to vertex form.
Form a perfect-square trinomial.
y = x2 + 2x +
− 1−
We want to complete the steps to convert the given quadratic equation into vertex form.
Eventually we will get:
y = (x + 1)^2 - 2
Vertex form of a quadratic equation.
For a quadratic equation with the vertex (h, k), the vertex form is:
y = a*(x - h)^2 + k
Here we start with:
y = x^2 + 2x - 1
1) First, we complete the perfect-square trinomial, we need to add and subtract 1 to get that:
y = x^2 + 2x - 1 + 1 - 1
2) Now we rewrite the equation to be able of completing squares:
y = (x^2 + 2x + 1) - 1 - 1
y = (x^2 + 2x + 1) - 2
3) Now we complete squares
y = (x + 1)^2 - 2
And this is the equation in vertex form, where you can see that the vertex is the point (-1, - 2)

[tex]\frac{11}{8}[/tex]Answer:
55 in by 40 in
Step-by-step explanation:
The perimeter (P) of a rectangle is calculated as
P = 2l + 2w ( l is the length and w the width )
Here l = [tex]\frac{11}{8}[/tex] y and w = y with P = 190
2y + (2 × [tex]\frac{11}{8}[/tex] y ) = 190
2y + [tex]\frac{11}{4}[/tex] y = 190 ( multiply through by 4 to clear the fraction )
8y + 11y = 760 , that is
19y = 760 ( divide both sides by 19 )
y = 40
Thus l = [tex]\frac{11}{8}[/tex] × 40 = 11 × 5 = 55 in and w = 40 in
