What is the y-value for the solution to the system of equations below? 10x + 8y = -24 5x+6y = 2​

Answers

Answer 1
Y = -1.4

The simplest way to find the answer is to cancel out the x - values. Set both equations equal to zero.
10x + 8y + 24 = 0
5x - 6y - 2 = 0
Multiple the second equation by -2 so the x terms cancel out when you add them together.
10x + 8y + 24 = 0
-10x + 12y + 4 = 0

20y + 28 = 0
20y = -28
Y = -1.4

A player at a basketball camp set a goal to make 55% if his shots. If he has 120 attempts, how many shots would he need to make in order to reach his goal?

Answers

Answer: 66

Step-by-step explanation:

From the question, we are informed that a player at a basketball camp set a goal to make 55% if his shots and that he has 120 attempts.

The number of shots that he would he need to make in order to reach his goal will be 55% of 120. This will be:

= 55% × 120

= 55/100 × 120

= 0.55 × 120

= 66

He would need to make 66 shots

4. The apples bought by Neetu was of weight 3 ¾ kg and the apples bought by Naren was of weight 2 ½ kg. Who bought more apples and by how much more did it weigh?

Answers

Answer:

5/4kg

Step-by-step explanation:

Given data

Weight of apples bought by Neetu=  3 ¾ kg

Weight of apples bought by  Naren=  2 ½ kg

From the numbers/weights above, Neetu bought more apples

=3 ¾ kg to simple fraction

= 15/4 kg

=2 ½ kg kg to simple fraction

= 5/2 kg

The difference is

=15/4-5/2

=15-10/4

= 5/4kg

Hence  Neetus Apples is 5/4kg morethan Narens Apples

8a^3

Step-by-step explanation:

Given that;

2^x = a, we want an expression for 8^(x + 1)

we have this as;

8^(x + 1) = 8^x * 8^1

8^x = (2^x)(3)

8^x is thus same as 2^3x

So replace 2^x by a

Thus, we have a^3

Multiply this by the 8 we had initially; that will give;

An hour before show time, only 105 people have arrived to the concert. According to the statistics, 95% of the people have yet to arrive. How many tickets were sold for the concert?

Answers

Answer: 2,100 tickets

Step-by-step explanation:

105 people have arrived for the concert yet it is said that 95% of people are yet to arrive. This means that the 105 people are 5% of the tickets sold.

Assume the total number of tickets sold is x:

5% * x = 105

0.05x = 105

x = 105 / 0.05

x = 2,100 tickets

Answer:

2100

Step-by-step explanation:

x= 2,100

5% x = 105

0.05x = 105

x = 105/0.05

The base of a regular pyramid is a hexagon.

What is the area of the base of the pyramid?
Enter your answer in the box. Express your answer in radical form.

Answers

Answer:

Step-by-step explanation:

For the single triangle

sin60=h/14, h=14sin60

cos60=b/(2(14)), b/2=14cos60 so the total area is nhb/2 where n is the number of sides

A=n(14sin60)(14cos60), since n=6

A=6(14sin60)(14cos60)

A=114.75cm^2

The hexagon is divided into 6 equal triangles. Then the area of the base of the pyramid is 509 square cm.

What is Geometry?

It deals with the size of geometry, region, and density of the different forms both 2D and 3D.

The base of a regular pyramid is a hexagon.

The hexagon is divided into 6 equal triangles. Then the height of the triangle will be

[tex]\rm a = 14 \sin 60^o\\\\a = 12.12[/tex]

Then the area of the triangle will be

[tex]\rm Area \ of \ triangle = 0.5 \times 14 \times 12.12\\\\Area \ of \ triangle = 84.84 \ cm^2[/tex]

Then the area of the base of the pyramid will be

[tex]\rm Area \ of \ base \ pyramid = 6 \times Area \ of \ triangle\\\\Area \ of \ base \ pyramid = 6 \times 84.84\\\\Area \ of \ base \ pyramid = 509.04 \approx 509 \ \ cm^2[/tex]

Step-by-step explanation:

Multiply numerator and denominator with the conjugate of (4 - √3).  

[tex]\frac{(6+\sqrt{27})(4+\sqrt{3})}{(4-\sqrt{3})(4+\sqrt{3})}[/tex]

= [tex]\frac{4(6+\sqrt{27})+\sqrt{3}(6+\sqrt{27})}{4^{2}-(\sqrt{3})^2}[/tex]

A TV and Washing machine were purchased for Rs 15000 each. If together, they are sold at Rs 35000, What is Profit and Profit%

Answers

Given:

A TV and Washing machine were purchased for Rs 15000 each.

Together, they are sold at Rs 35000.

To find:

The profit and profit%.

Solution:

A TV and Washing machine were purchased for Rs 15000 each. So, the total cost price is

[tex]C.P.=15000+15000[/tex]

[tex]C.P.=30000[/tex]

Together, they are sold at Rs 35000. So, the selling price S.P. is 35000.

Now,

[tex]Profit=S.P.-C.P.[/tex]

[tex]Profit=35000-30000[/tex]

[tex]Profit=5000[/tex]

And,

[tex]Profit\%=\dfrac{Profit}{C.P.}\times 100[/tex]

[tex]Profit\%=\dfrac{5000}{30000}\times 100[/tex]

[tex]Profit\%=\dfrac{50}{3}[/tex]

[tex]Profit\%\approx 16.67[/tex]

Therefore, the profit is Rs. 5000 and the profit percent is 16.67%.
