What Is The Value Of Y?Enter Your Answer In The Box.

Answers

Answer 1
When dealing with the angles of triangles, they are always going to equal 180 degrees. 
So, 79 + 37 + x = 180
116 + x = 180
-116         -116
-------------------
x = 64 degrees

To check that you can just add them all together and see if you get 180.
64 + 79 + 37 = 180
Answer 2
y= 64°

79°+37°+?°=180°   so you do it backwards.....
180°-79°-37°=64°

Hope this helps :)

Brandon is shopping at Old Navy during a sale. All shorts are $16 each and all t-shirts are $10 each.He has $100 to spend and would like to purchase at least 2 pairs of shorts.
a) Write a system of linear inequalities to represent
this situation, then graph.
b)Using your graph, give two possible combinations
of shorts and Brandon can buy.

Answers

Let
x = the number of shorts bought
y =  the number of t-shirts bought

A pair of shorts costs $16 and a t-shirt costs $10. Brandom has $100 to spend.
Therefore
16x + 10y ≤ 100
This may be written as
y ≤ - 1.6x + 10                 (1)

Brandon wants at least 2 pairs of shorts. Therefore
x ≥ 2                               (2)

Graph the equations y = -1.6x + 10 and  x = 2.
The shaded region satisfies both inequalities.

Answer:
Two possible solutions are
(a) 3 pairs of shorts and 4 t-shirts,
(b) 4 pairs of shorts and 2 t-shirts.

Two possible solutions are (a) [tex]3[/tex] pairs of shorts and [tex]5[/tex] t-shirts

                                             (b) [tex]4[/tex] pairs of shorts and [tex]3[/tex] t-shirts.

[tex]x=the\; number\; of shorts\\y=the\; number\; of\ t-shirt\; bought[/tex]

So equation formed is

[tex]16x+10y\leq 100[/tex]

[tex]10y\leq 100-16x\\y\leq 10-1.6x[/tex]---Eq [tex]1[/tex]

Bradon wants at least [tex]2[/tex]  pair of shorts.Therefore

[tex]x\geq 2[/tex]--Eq [tex]2[/tex]

Now put,

[tex]x=3 \\y=10-1.6(3)\\y=10-4.8\\y=5\\[/tex]

Hence [tex]3[/tex] shorts and [tex]5[/tex] t-shirts

Now put,

[tex]x=4 \\y=10-1.6(4)\\y=10-6.4\\y=3\\[/tex]

Now graph the equation,

Solve for x

Answers

if you subtract 2x from each side you get 5x-0.15=0.6 because the subtraction of 2x on the right of the equal sign cancels out. Then, if you add 0.15 to both sides you will get 5x=0.75. Finally, if you divide both sides by 5 you get x = 0.15.

Hi there,

This question is a bit weird lol, but anyway here is how to do it and the answer:

What is the common term for the set of all points with x- coordinate zero?

A. X axis

B. Y axis

C. Coordinate plane

D. Origin

Answers

I think the correct answer would be option B. The common term for the set of all points with the x-coordinate that is zero is the y-axis. All of the points that is found in the y-axis contains zero as the x-coordinate of the point. So, it should be the y-axis the correct answer.

Answer:

Option B is the correct answer.

Step-by-step explanation:

We have X axis, Y axis and origin in coordinate plane.

Origin is the point for which both x and y coordinate is zero.

X axis is the set of all points with y- coordinate zero.

Y axis is the set of all points with x- coordinate zero.

Here we are asked to find the common term for the set of all points with x- coordinate zero.

That is Y axis

Option B is the correct answer.

The difference of the squares of two positive consecutive even integers is 20 . find the integers. use the fact​ that, if x represents an even​ integer, then xplus 2 represents the next consecutive even integer.

Answers

If x is the first number, x+2 is the next consecutive even integer. The difference (subtraction) of their squares equals 20. Therefore:
(x+2)²-x²=20...expand this:
x²+4x+4-x²=20 
x²+4x+4-x²=20
4x+4=20
4x=16
x=4. Therefore the next consecutive even integer is x+2=6.

Multiplying the second equation by 4/3 and adding it to the first, we get 36=9x and by dividing both sides by 9, we get x=4. Next, we can plug that into the second equation (it doesn't matter which equation) to get 3*4-3y=18=12-3y. Subtracting 12 from both sides, we get 6=-3y and by dividing both sides by -3 we get y=-2

A certain roller coaster can accommodate 1600 riders per hour a digital sign states that there are 345 people in line if you get in line about how many minutes will it take you to get to the front of the line

Answers

Given that the roller coaster can accommodate 1600 riders per hour, thus the roller coaster can accomodate 1600 / 60 = 26.67 riders per minute.

Given that there are 345 people in the line, the number of minutes it will take for the 345 persons to get into the roller coaster is given by 345 / 26.67 = 12.94 minutes.

Therefore, it will take you 12.94 minutes to get to the front of the line.

The ranges of the diameter of the wheels that the company manufactures can be calculated by adding or subtracting the given tolerance from the desired diameter. The lower limit is calculated by subtracting the allowance while the upper limit is obtained by adding the allowance. 
                     lower limit = 70 cm - 0.02 cm = 6.98 cm

Answers

First calculate the future value of the annuity
The formula to find the future value of an annuity ordinary is
Fv=pmt [((1+r/k)^(kn)-1)÷(r/k)]
Fv future value?
PMT quarterly payment 1500
R interest rate 0.12
K compounded quarterly 4
N time 4 years
Fv=1,500×(((1+0.12÷4)^(4×4)
−1)÷(0.12÷4))
=30,235.32

Now compare the amount of the annuity with amount of the gift
30,235.32−30,000=235.32
So as you can see the amount of the annuity is better than the amount of the gift by 235.32

Second offer is better

A jet plane, flying 120 mph faster than a propeller plane, travels 3520 miles in 3 hours less time than the propeller plane takes to fly the same distance. how fast does each plane fly?

Answers

Final answer:

The propeller plane flies at a speed of 880 mph, and the jet plane flies at a speed of 1000 mph.

Explanation:

Let the speed of the propeller plane be represented by x mph. Since the jet plane is flying 120 mph faster, its speed can be represented as x + 120 mph.

We know that the distance traveled by both planes is the same, so we can set up the equation:

x * t = (x + 120) * (t - 3)

where t is the time taken by the propeller plane.

Simplifying the equation, we get:

x * t = xt + 120t - 3x - 360

Rearranging the terms, we have:

120t - 3x = 360

Since we have two variables, we need another equation. We can use the formula for distance, which is given by:

Distance = Speed * Time

For the propeller plane, we have:

D = x * t

For the jet plane, we have:

D = (x + 120) * (t - 3)

Since the distance is the same, we can equate these two equations:

x * t = (x + 120) * (t - 3)

x * t = xt + 120t - 3x - 360

Rearranging the terms, we get:

120t - 3x = 360

Solving the system of equations, we find that x = 880 mph and x + 120 = 1000 mph.

Step-by-step explanation:

Distance traveled in [tex]1[/tex] day = [tex]113 km[/tex]

Distance traveled in [tex]1[/tex] week = [tex]113*7 = 791 km[/tex]

Mileage of car = [tex]41.0 mi/gal = \frac{41*1.60}{3.78} = 17.35 km/liter[/tex]

Total gas consumed = [tex]\frac{791}{17.35} = 45.49liter[/tex]
