Xander writes math textbooks that sell x dollars each. he received a bonus of $25,000 for signing a contract, and he receives 8% commission on each book sale. express the total amount of income xander earns from selling y books algebraically
The total amount of income Xander earns from selling y books algebraically is C = 25000 + xy + 0.08y.
What is an equation?An equation is the statement that illustrates the variables given. In this case, two or more components are taken into consideration to describe the scenarios.
In this situation, Xander writes math textbooks that sell x dollars each, he received a bonus of $25,000 for signing a contract, and he receives 8% commission on each book sale.
c = total amount
y = number of books.
The total amount of income will be:
= 25000 + (x × y) + (8% × y)
= 25000 + xy + (0.08 × y)
C = 25000 + xy + 0.08y

Line segment SU is a diameter of circle V.
What is the measure of arc S T?
56°
68°
112°
163° (it is 56!)
Answer:
Answer: 112°
Step-by-step explanation:
Angles in a Circle
An inscribed angle is formed between two chords whose vertices lie on the circumference of a circle. The figure shows three chords: TU, SU, and ST. SU happens to also be a diameter because it goes through the center of the circle V.
ST and SU form an inscribed angle of 34°. The corresponding central angle is TVU and its measure is
[tex]m\angle TVU=2*34^\circ=68^\circ[/tex]
The required measure of the arc ST is the measure of the angle SVT. Note that SVT and TVU are complementary, thus:
[tex]m\angle TVU+m\angle SVT=180^\circ[/tex]
Solving for the measure of SVT:
[tex]m\angle SVT=180^\circ-m\angle TVU[/tex]
[tex]m\angle SVT=180^\circ-68^\circ=112^\circ[/tex]

Answer:
Step-by-step explanation:
we know that the interior angles are supplementary,

2x-10+4x+16=180
6x=180+6
6x=186

A motorboat travels Downstream on a river for 5 hours. The speed of the current is 2 km/h. The river flows into a still Lake and the motorboat continues for two more hours. The distance covered by the boat on the river was 40 km more than the distance that was covered on the lake. What is the speed of the motorboat in still water?
Answer:
I think it is 10 km/hr
Step-by-step explanation:
5 hrs = 40 more with 2 km/hr current
2 hrs= less 40 no current
40-2x5=30
30 without current for three hours
30/3=10 km/hr no current
CHECK
10x2=20
10x5=50+2x5=60
The speed of the motorboat in still water is 10 km/hr
A motorboat travels downstream on a river for 5 hours.
The speed of the current = 2 km/h
The river flows into a still lake and the motorboat continues for two more hours.
The distance covered by the boat on the river was 40 km more than the distance that was covered on the lake.
We have to determine the speed of the motorboat in still water
Let the speed of motorboat in still water = m km/h
Given that
The speed of river current = 2 km/hr
The river runs into a still lake
The motorboat continues to travel for 2 more hours
The distance traveled by the motorboat in two more hours in the lake = 2m km
The distance covered by the boat in the river = (40 +2m) km
Net speed of the boat in the river = (m +2 ) km/hr
Let t be the time spent by motorboat into the river.
[tex]\rm Time = \dfrac{Distance}{Speed}[/tex]
[tex]\rm t = \dfrac{40+2m }{m +2}..........(1)[/tex]
Given that the motorboat travels downstream of the river for 5 hrs
so on putting t = 5 in equation (1).
[tex]\rm 5 = \dfrac{40 +2m }{m+2}\\\\5m +10 = 40 +2m\\5m -2m = 40-10\\3m = 30\\m = 10 km/h[/tex]
So the speed of the motorboat in still water is 10 km/hr

That would be 6x+35.
Step-by-step explanation:
Given that you do not provide a way to determine the value of x, we cannot simply 6x, but we can simplify 21+14 by solving it and getting 35, resulting in the expression 6x+35.

The solution of the inequality is x≥-13 and the graph c represents the inequality, option c is correct.
The given inequality is -1/4(12x+8)≤-2x+11.
Let us solve for x:
Apply distributive property:
-3x-2≤-2x+11
Add 2 on both sides of the inequality:
-3x+2x≤11+2
Combine the like terms:
-x≤13
x≥-13
Hence, the graph of c represents the solution of the inequality.
