Answer:
x = 12 cm
y = 2 cm
Step-by-step explanation:

y = 6 cm / 3 = 2 cm
How many degrees Fahrenheit is -3°C? Help please
Answer:
26.6 degrees
Step-by-step explanation:
Formula
(°C × 1.8) + 32 = °F
(-3°C × 9/5) + 32 = 26.6°F
26.6
To convert temperature readings from celsius scale, formula used is -
[tex]\green{ \underline { \boxed{ \sf{F = \frac{9}{5}C +32 }}}}[/tex]
where
F = temperature in FahrenheitC = temperature in CelsiusPutting Values -
[tex]\begin{gathered}\\\implies\quad \sf F = \frac{9}{5}\times(-3) + 32 \\\end{gathered} [/tex]
[tex]\begin{gathered}\\\implies\quad \sf -\frac{27}{5} + 32 \\\end{gathered} [/tex]
[tex]\begin{gathered}\\\implies\quad \sf -5.4 + 32 \\\end{gathered} [/tex]
[tex]\begin{gathered}\\\implies\quad \sf 26.6\degree F \\\end{gathered} [/tex]
Therefore, 26.6⁰ Fahrenheit is equivalent to -3⁰C.

What is the area of the playground shown? The edges of the playground meet at right angles, except for the edge whose length is not given. Show all work.
Answer:
520,000
Step-by-step explanation:
1400 x 200 = 280000
(400 + 800) x 400 /2 = 240000
240000 + 280000 = 520000
The area of the playground is 520000 square feet.
What is the area?The area is the amount of area occupied by an object's flat (2-D) surface or shape.
Given that the edges of the playground meet at right angles, except for the edge whose length is not given.
And to find the area of the composite figure,
find all the areas separately.
There is a square with a side length of 400 feet.
A rectangle with dimensions 200 feet by 600 feet.
Another rectangle with dimensions 1400- 600 = 800 feet by 200 feet.
And a triangle with a base of 400 feet and a height of 400 feet.
The area of the playground = (400 x 400) + (200 x 600) + (800 x 200) + (1/2 x 400 x 400)
The area of the playground = 160000 + 280000 + 80000
The area of the playground is 520000 square feet.
Therefore, the area is 520000 square feet.

SHADOWS A rectangular billboard casts a shadow on the ground in the shape of a parallelogram. What is the area of the ground covered by the shadow? Round your answer to the nearest tenth.
Answer:
Its still a rectangle, just move the triangles, you get 450
Step-by-step explanation:
If you think of it like a triangle, you can use the base, the 90 degree angle, and the hypotenuse to get the area, do it twice since there are two, and your result is 225 for one triangle, 450 for both.
Long-billed curlews eat many different kinds of insects, including grasshoppers, as a source of food. It has been shown that pesticide use kills many of these insects. How would you expect an increase in pesticide use to affect to the population of long-billed curlews in the same area
An increase in the use of pesticides in the same area would lead to the population of long - billed curlews decreasing.
How will the population of long-billed curlews be affected by pesticides ?An increase in pesticide use that kills many of the insects that long-billed curlews eat, such as grasshoppers, would likely have a negative impact on the population of long-billed curlews in the same area.
Since grasshoppers and other insects are a primary food source for long-billed curlews, a decline in insect populations due to pesticide use could lead to reduced food availability and increased competition for remaining food sources. This could lead to decreased population size and potentially even local extinctions.

Which fraction below represents a terminating decimal?
A.
B.
C.
D.
Answer:
3/10
Step-by-step explanation:
The fraction, 1/12, can be written as 1/4 * 1/3. Since we know that 1/3 = 0.333333... and it doesn't terminate, we know that 1/12 doesn't terminate. Similarly 2/9 = 2/3*1/3 and 2/3 = 2*1/3, and neither of these fractions terminate. But, when dividing 3/10, you get 0.3, which terminates.

The table represents the balance of Sylvia's loan, y, over a period of 24 months, x. She used technology to create the scatter plot shown and
determined the best fit equation to model the data, y=-382.05x +
25,077.40. Determine how long it will take to reach the given balances
Using the given linear function, it is found that:
The balance will be of approximately $17,000 in month 21.The balance will be of approximately $0 in month 66.What is the function for the balance?The balance after x months is modeled by:
y = -382.05x + 25077.4.
Hence, it will be of approximately $17,000 at x for which y = 17000, hence:
17000 = -382.05x + 25077.4
x = (25077.4 - 17000)/382.05
x = 21.
We apply the same logic to find when it will be of approximately 0.
0 = -382.05x + 25077.4
x = (25077.4 - 0)/382.05
x = 66.

Answer:
[tex]y=\frac{x-9}{-8}[/tex]
Step-by-step explanation:
1. change f(x) to y
2. switch x and y
[tex]x= -8y+9[/tex]
3. solve for y
[tex]x-9=-8y[/tex]
[tex]y= \frac{x-9}{-8}[/tex]
Answer: y = (9-x) / 8
Step-by-step explanation:
set f(x) = y
y = -8x + 9
to find inverse repalce all y values with x and x values with y then solve for y again
x = -8y + 9
x - 9 = -8y
y = (x-9) / -8
distribute -1 through the numerator and make 8 positive
y = -x+9/8
y = (9-x)/8

Using simple interest, it is found that her interest charge this month will be of $30.
Simple InterestSimple interest is used when there is a single compounding per time period.

I(t) = Prt
In which:
P is the initial amount.r is the interest rate, as a decimal.In this problem, considering the time in years, the parameters are:
[tex]P = 2000, r = 0.18, t = \frac{1}{12}[/tex]

Amy planted a flower garden with rows of blue flowers, b, and rows of yellow flowers, y. Each row of blue flowers has 5 flowers, and each row of yellow flowers has 7 flowers. Which expression represents the total number of flowers Amy planted?
A. 5 + r + 7 + b
B. 5b + 7y
C. 5 × 7 + b × y
D. 5y + 7b
This problem has two variables, b and y. The b value is the number of rows of blue flowers, and the y value is the number of rows of yellow flowers.
In every row of blue, there are 5 flowers.
In every row of yellow, there are 7 flowers.
