The Previous Owner Recalled That The Area Of Sail B Was 108 Square Feet. What Is The Length Of The Base

Answers

Answer 1

Answer:

Number of small candles = 12

Number of large candles = 16

Step-by-step explanation:

Total candles = 28

x + y = 28 ---------------(I)

Cost of 'x' small candles = 4 *x = 4x

Cost of 'y' large candles = 6 *y = 6y

Total amount = $144

4x + 6y = 144 -------------(II)

Multiply equation (I) by (-4) and then add the equation. So, x will be eliminated and we can find the value of 'y'

(I) * (-4)            -4x - 4y = -112

(II)                    4x  + 6y = 144              {Now, add}

                              2y = 32

                               y = 32/2

y = 16

Plug in y = 16 in equation (I)

x + 16 = 28

      x = 28 - 16

x = 12

D sounds like the most probable choice.

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.

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?

Answers

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

What is the measure of arc S T?

163° (it is 56!)

Answers

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]

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

Answers

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
