Answer:
x=112, y=28, z=22
Step-by-step explanation:
68°+4y°=180° (adj angles on a str line)
4y=180-68
=112
y=112÷4
=28
x°+68°=180° (int angles)
x=180-68
=112
(5z+2)°=x° (corr angles)
5z+2=x
5z+2=112
5z=112-2
=110
z=110÷5
=22

the price of 10 chairs is equal to that of 4 tables. the price of 15 chairs and two tables together is 4000$ the total price ( in $) of a chair and table is?
Answers
Answer:
$700 for a chair and a table
Step-by-step explanation:
Let t and c represent the price of a table and a chair, respectively. The given relations are ...
10c = 4t
15c +2t = $4000
Divide the first equation by 2 and substitute for 2t:
5c = 2t
15c +5c = $4000
20c = $4000
c = $200
t = 5c/2 = 5($200)/2 = $500
The total price of a chair and a table is ...
$200 +500 = $700 . . . . price of a chair and a table

which is the correct word form of 8.16
a . eight and sixteen tenths
b. eight and sixteen hundredths
c. eight hundred sixteen hundredths
d. eight hundred sixteen thousandths
Answers
The correct word form of 8.16 is b. eight and sixteen hundredths
Since the number is 8.16, we have 8.16 = 8 + 0.16 = 8 + 16/100
Since we have 8 in the units place, it is pronounced eight.
Also, we have our decimal part 0.16 = 16/100 which is pronounced as sixteen hundredths.
So, combining both we have eight and sixteen hundredths.
So, the correct word form of 8.16 is b. eight and sixteen hundredths

An interior designer hangs canvas paintings along a hallway. If the interior designer uses canvas paintings with length measuring
9
inches and places them side by side along the hallway that has a length of
24
feet, how many paintings does the designer hang?
Answers
The number of paintings the designer can hang is 32.
In order to determine how many paintings the painter can hang, the length of the hallway would be divided by the length of the paintings.
Number of paintings = length of hallway / length of paintings
The unit of measurement of the hallway and the paintings have to be the same length,
1 foot = 12 inches
24 feet x 12 = 288 inches
Number of paintings = 288 / 9 = 32 paintings

Does the equation Y equals 2X +3 represent a proportional relationship
Answers
Plug in 0 for x
Y = 2(0) + 3
Y = 3, therefore the point (0,0) cannot work because there’s a y- intercept.
Proportional means you will start at the point of origin (0,0) but this case, that is not possible.

A stone is launched into the air from a height of 240 feet. The height, h, of the stone, in feet, t seconds after launch is given by
the formula h = 16t^2 + 32t+ + 240. After how long will the stone hit the ground?
Answers
A projectile is an object launched into space, and moving under the influence of gravity and momentum. The stone here is an example. Thus, the time taken for the stone to reach the ground is 10 seconds.
On launching of the stone into space, it behaves as a projectile. Thus moving under the influence of gravity and its momentum. Its momentum is the product of its mass and velocity.
The height h, is given as:
h = 16[tex]t^{2}[/tex] + 32t + 240
Differentiating the expression with respect to t, we have;
32t + 32 = 0
t = -1 seconds
Substitute the value of time, t, in the equation for the height;
h = 16 - 32 + 240
= 224
h = 224 m
Total height, S = 240 + 224
= 464
S = 464 m
The total height covered by the stone is 464 m.
From the second equation of free fall,
S = Ut + [tex]\frac{1}{2}[/tex]g[tex]t^{2}[/tex]
S = [tex]\frac{1}{2}[/tex]g[tex]t^{2}[/tex]
464 = [tex]\frac{1}{2}[/tex]*9.8*[tex]t^{2}[/tex]
[tex]t^{2}[/tex] = [tex]\frac{928}{9.8}[/tex]
= 94.694
t = [tex]\sqrt{94.694}[/tex]
= 9.7311
t ≅ 10 seconds
The time taken for the stone to hit the ground is 10 seconds.
Thus option A is the required answer.

can someone write −4 and (6, 4) in standard form. -4 is the slope. I need it as one answer.
Answers
Answer:
y = -4x + 28
Step-by-step explanation:
yeah-ya........ right?
Step-by-step explanation:
what is the standard form for your teacher ?
because that is absolutely not agreed on worldwide (and even between teacher and teacher in the same region).
there are 2 main forms :
the general slope intercept form is
y = ax + b
a is the slope. and is here -4.
b is the y-intercept (the point, where the line crosses the y-axis, meaning the y value when x=0).
we get b by using the point coordinates in the half finished equation :
4 = -4×6 + b = -24 + b
28 = b
so, the equation is
y = -4x + 28
the general slope point form is
y - y1 = a(x - x1)
where a (often called m) is again the slope, and x1, y1 are the coordinates of a given point.
so, we have
y - 4 = -4(x - 6)

Step-by-step explanation:
You add the "columns." The equations are arranged so that like terms are stacked vertically. 3x and 7x are like terms; when you add them, you get 10x.
-y and y are like terms; when you add them, you get 0 (that doesn't appear in the sum).
-5 and 15 are like terms; add them to get 10.
The sum of the two equations is the equation 10x = 10.
