A rectangle has an area of 112 square yards. Its width is nine yards less than the length. Write an equation that models this problem
Step-by-step explanation:
L = length
W = width
L = W + 9
A = 112 = LW = (W+9)W
So,
W2 + 9W = 112
W2 + 9W - 112 = 0
Factoring
(W-7)(W+16) = 0
W = 7, -16
We discard W = -16, since a measurement cannot be negative.
W = 7
And since L = W + 9, then L = 7 + 9 = 16
This is a 16x7 rectangle
Zayn puts garland around a square window. He uses 888 meters of garland.
What is the height of the window?
Answer:
222 meters
Step-by-step explanation:
Zayn puts a total of 888 meters of garland around a square window.
Because a square has all equal sides, divide the amount of garland he used by 4 to find how much is used per side:
888 ÷ 4 = 222
So, the height of the window is 222 meters.

I find a graphing calculator shows the zeros of higher-degree polynomials easily. The function graph is attached.
For the purpose here, the vertical scale factor π/3 can be eliminated, as it does not change the values of the zeros. That is, the polynomial we need to solve is x²(x -15) +275 = 0.
It turns out that a reasonable iterator for finding a solution is x' = √(275/(15 -x)). x = 5 is a reasonable starting point. The iterator is what you get by solving for the x outside the parentheses in the above cubic equation.
If the word is a proper noun, choose the answer that begins with a capital letter. If the word is a common noun, choose
the answer that begins with a small letter.

Answer:
$2.60
Step-by-step explanation:
You pay ...
app cost + tax
$2.50 + 4% × $2.50 = $2.50×(1 + 4%) = 1.04×$2.50 = $2.60
You pay $2.60 for the app.

396 students divided by 9 buses=44 students per bus
In slope intercept form y=mx+b, the y-intercept is located at (0,b).
a. What equation results from substituting (0,b) for (x1,y1) in the point-slope form y-y1= m(x-x1)?
b. How are the slope-intercept and the point-slope forms related?
a . When (0,b) is substituted for (x1,y1) in the point-slope form y-y1=m(x-x1). the result is__
( Type an equation )
Please Help asap
Step-by-step explanation:
a. Substituting (0,b) into the point-slope form, we get y = mx + b. Plug in 0 to the x1 value and plug in b into the y1 value. Add b to both sides and you should get y = mx+b.
b. Slope-intercept shows how to get specific x or y values at a point if three of the four variables (y, m, x, or b) are known. Point slope form is used mainly when finding the slope from two distinct points. (Later, you'll learn it's importance in the definition of a derivative :).)
c. y = mx + b. Refer to a.
Answer:
a) y-b=m(x-0)
b) (x1, y1) , point-slope, y, slope-intercept

supsuppose you divide a bar diagram into 25 equal-size sections and shade 5 sections what percent is modeled in the diagram
5 shaded sections are 20% of 25 equal size sections.
Given that, you divide a bar diagram into 25 equal-size sections and shade 5 sections.
What is percentage?Percentage is defined as a given part or amount in every hundred. It is a fraction with 100 as the denominator and is represented by the symbol "%".
Now, 5/25 × 100
= 0.2 × 100
= 20%
Therefore, 5 shaded sections are 20% of 25 equal size sections.

A sample of fish is taken from two different lakes.
Seventy fish are taken from Lake A and the mean length of the
fish is 35 cm.
Thirty fish are taken from Lake B and the mean length of the
fish is 42 cm.
Calculate the mean length of the 100 fish.
Answer:
So, 100 fish taken from Lake A would have a mean length of 50 cm and 100 fish taken from Lake B would have a mean length of 140 cm
Step-by-step explanation:
1 fish from Lake A would be 0.5 cm long you calculate that by dividing 70 from 35 and you calculate the fish from Lake B by dividing 30 from 42 which would be 1.4 cm, (english is not my first language so I hope you understood everything :D)
