Final answer:
Kristine bought 12 roses. This was found by subtracting the cost of the vase from the total spent and then dividing by the cost of one rose.
Explanation:
To find how many roses Kristine bought, we can set up the following equation:
$5.99 + $1.25x = $20.99
Here, x represents the number of roses. To solve for x, we can subtract $5.99 from both sides of the equation:
$1.25x = $20.99 - $5.99
$1.25x = $15
Finally, divide both sides of the equation by $1.25 to solve for x:
x = $15 ÷ $1.25
x = 12
Therefore, Kristine bought 12 roses.

A. For each increase of $1000 in private-party value, the trade-in value increases by $1100.
B. For each increase of $1000 in private-party value, the trade-in value increases by $1037.
C. For each increase of $1000 in trade-in value, the private-party value increases by $1100.
D. For each increase of $1000 in trade-in value, the private-party value increases by $1037.
Answers
In the question, they GIVE you the equation for the line:
y = 1.1 x + 1.37 .
When you look at the graph, you notice that the numbers
are actually thousands, so the equation is really
y = (1.1 thousand) x + (1.37 thousand)
or
y = 1,100 x + 1,370 .
The slope of the line is 1,100 .
Choice 'C' says that, because
the slope of any graph = (change in 'y') / (change in 'x') .
because when you see the chart when the trade in value goes up so does the private party value. The chart shows 1,000 in trade in value increasing and then private party value also increase by 11,000.
inscribed angle = 1/2 · (intercepted arc) and
intercepted arc = central angle.
Be sure to use important vocabulary like “inscribed angle,” “central angle”, and “intercepted arc”.
Answers
Answer:
Angle of the intercepted arc is equal to the angle at the centre (central angle) but B is not the centre hence XBY is not 144°.
Angle at the circumference (inscribed angle) is half of the central angle, but XBY is not the central angle, so it's not 2×72.
Hence not 144°

What is the acceptable range for the densitometer reading?
exactly 1.8
from 0 to 3.6
from 1.0 to 2.6
from 1.62 to 1.98
from 1.8 to 1.98
Answers
1.8 * 10/100 = 0.18
If we add this value to the original value,
1.8+0.18 = 1.98
If we subtract this value from the original value,
1.8-0.18 = 1.62
therefore the range will be,
from 1.62 to 1.98

written any more clearly. Sooner or later, you have to stop telling yourself that you have
no clue, settle down, and carefully read the words that are right there on the page.
I'll tell you one more detail that's not in the problem: "breadth" means "width".
Now. The problem clearly tells you all of these things, in this exact order:
=> Area of the walls = (2 x height) x (length + width)
=> length = 8m
=> width = 6m
=> height = 2.5m
Is there a reason you can't take the numbers for length, width, and height,
and write them in the formula for the area ? Do I have to do all the work ?
Area = (2 x height) x (length + width)
Area = (2 x 2.5m ) x ( 8m + 6m )
Do the arithmetic inside the parentheses:
Area = ( 5m ) x ( 14m )
Do the multiplication:
Area = 70 m² .
You will never see a problem that comes any closer to answering itself for you.
