a rectangular window is 36 inches long and 24 in wide. tammy would like to buy a screen for the window. because of the screen is based on the number of square feet the screen is use the fraction to find the area of the window in square feet.
Answer:
144 Sq
Step-by-step explanation:
The area of the rectangle formula is Length x Width. Given 4 ft and 3 ft, we can find the area. The screen would be 12 Sq. Feet since the question is asking for inches we must now convert this.

Answer:
ans is 504m²
Step-by-step explanation:
given = side of square=18m
height of triangle=12m
formula= surface area of square + surface area of 4 triangles
surface area of square = 4 × length
= 4×18
=72m²
surface area of triangle = 1/2×base ×height
= 1/2×18×12 ( the base lies on the side of the squre so the base is also 18m)
= 108m²
therefore, surface area of 4 triangles = 4×108=432m²
therefore the surface area of the given figure= surface area of aquare + surface area of the 4 triangles
surface area of square= 72 +432
=504m²
a ribbon is 4m long. how many pieces each of 30cm long can be cut from the ribbon
9514 1404 393
Answer:
13
Step-by-step explanation:
4 m is 400 cm, so the number that can be cut is ...
(400 cm)/(30 cm/piece) = 13 1/2 pieces
13 pieces can be cut that are 30 cm long.
Answer:
13 whole pieces
Step-by-step explanation:
4m=400cm
400cm÷30cm=13.333333
you can't get 0.33333333(goes on forever) of a ribbon so its 13

What is the equation of the circle, with center (4, 2) and radius 5 units?
Answer:
Step-by-step explanation:
Let us begin by just getting the equation of the circle first.
(x - 4)^2 + ( y - 2)^2 = 5^2
(x - 4)^2 + ( y - 2)^2 = 25
Now I'm going to graph that equation and discuss it here.
I have graphed the second equation above.Notice that the center is at (4,2) just as the question requested.A second point was put at (4,7). That was to show you that the radius is 5 units. You can calculate that it is 5 units by noticing that 7 - 2 = 5 So the distance from the center to (4,7) is 5 units which is the amount of the radius.Notice that the numbers representing the center have been reversed in sign. That is always done for a circle. The center's coordinates are always the negative of the coordinates given. You will be told why later.can anyone help me please

Out of a total of N students at a school, the number of students who have seen a new television program increases at a rate proportional to the product of the number of students who have seen the program and the number of students who have not seen the program. If S denotes the number of students who have seen the program at time t, which of the following differential equations could be used to model this situation, where k is a positive constant?
a. ds/dt = KS
b. ds/dt = kt(N-t)
c. ds/st = KS(N-S)
d. ds/dt = KS(S-N)
Answer:
ds/dt = kN(N-S)
Step-by-step explanation:
Given
Total number of student = N
number of students who have seen the program = S
Number of students who have not seen the program = N-S
The product of the number of students who have seen the program and the number of students who have not seen the program = N(N-S)
If the rate of number of students who have seen a new television program increases at a rate proportional to the product of the number of students who have seen the program and the number of students who have not seen the program, then:
ds/dt = kN(N-S)
k is the proportionality constant
Is this a Percent Increase or Decrease Problem?
Kemyah bought a necklace for $260 that was marked
up by 30%.
Answer:
increase
Step-by-step explanation:
....................
Answer:
Percent Increase
Step-by-step explanation:
Percent Increase because if the necklace was bought for $260, and was marked up by 30%, it means it was originally a lower price, that was multiplied by 130%.
Explanation by algebra:
x + 0.30x = 260
1.3x = 260
x = 260/1.3
x = 200
The necklace was originally $200, and it was marked up by 30$, making it $260.

17. Stella is competing in a diving competition. Her height in feet above the water is
modeled by the function h=-16t? + 8t + 48, where t is the time in seconds after she jumps
from the diving board. At what time will Stella land in the water? (Round to the nearest
hundredth, if necessary.)
9514 1404 393
Answer:
after 2 seconds
Step-by-step explanation:
We want to find t such that h = 0.
0 = -16t² +8t +48
0 = 2t² -t -6 . . . . . . . divide by -8
0 = (t -2)(2t +3) . . . . factor
The only positive solution is t = 2, which makes the first factor zero.
Stella will land in the water at t = 2 seconds.

one step equation
Answer:
x=10
Step-by-step explanation:
x-1 = 9
add 1 on both side
x-1+1=9+1
x=10
Answer:
The answer would be 10
Step-by-step explanation:
1) Add 1 to both sides.
[tex]x = 9 + 1[/tex]
2) Simplify 9 + 1 to 10.
[tex]x = 10[/tex]
Hence, the answer would be 10.

2. Use the distributive property to write an expression that is equivalent to 5(-2x-3)
Answer:
-10x-15
Step-by-step explanation:
So first we start off with 5(-2x-3)
Next, we distribute the 5 to the -2x to get -10x.
Next, we distribute the 5 to the -3 to get -15.
Therefore,
-10x-15 is correct
Answer:
-10x-15
Step-by-step explanation:
It's 10x-15, because you just need to simplify it.
It is the same thing as (5 x (-2x)) - (5 x 3), if you use the distributive property.
that is the same as -10x-15
Determine the amplitude or period as requested . Amplitude of y = - 1/3 * sin x
Answer: amplitude and period are two different things. The amplitude is -1/3, and the period is 360 degrees.
Step-by-step explanation: to find the amplitude, you just look at what number is in front of sin. If there isn't one, an amplitude of 1 is implied (in this case. Keep in mind that different functions have different standards).
To find the period, you take term b (which is what comes after sin). In this case, b is 1 because there's no specific number there. Again, it's implied. Because this is sin and not tan, for example, you take 360/b=period. 360/1=360 degrees.

A diamond retailer buys a ring from his supplier

diamond with a 6% sales tax?
Answer:
nerd is 18
Step-by-step explanation:
xsas
Answer: $1,947.75
Step-by-step explanation: First, the mark up is 110% of the total, which is $875. 110% of 875 is $962.50, which you add to the total ($875) since it is mark up. $962.50 + $875 = $1837.50. Finally, 6% of $1837.50 is $110.25 so you add this to your new price ($1837.50) since the 6% is the sales tax. $1837.50 + $110.25 = $1947.75

Click the score on the graph where you think the
balancing point would be for this data.
Answer:
The balancing point is 23
Step-by-step explanation:
Given
The above graph
Required
Determine the balancing point
This simply means that we calculate the mean.
From the above graph, we have:
[tex]\begin{array}{cc}x & {f} & {21} & {3} & {22} & {5} & {28} & {1} & {29} & {1}\ \end{array}[/tex]
So, the mean is:
[tex]\bar x = \frac{\sum fx}{\sum f}[/tex]
[tex]\bar x = \frac{21*3+22*5+28*1+29*1}{3+5+1+1}[/tex]
[tex]\bar x = \frac{230}{10}[/tex]
[tex]\bar x = 23[/tex]
Hence, the balancing point is 23
The five members of the Roberts family went to a high school soccer game. The total cost was $44.
They paid $10 less because they used a $10 coupon, how much was the cost per person?
Answer:
%6.8
Step-by-step explanation:
The five members of the Roberts family went to a high school soccer game. The total cost was $44.
They paid $10 less because they used a $10 coupon, how much was the cost per person?
members in the family = 5
total cost = $44
cost per person = 44/5
= $8.8
Now, they got $10 coupon so they paid $10 less.
therefore,
New total cost = $44-$10
= $34
New per person cost = $34/5
= $6.8
Answer:
they paid $8.80 cents per person without coupan but with coupon they paid $6.80
Step-by-step explanation:
i divied 44 by 5 to get $8.80 without cupon but woth coupan is subracted 34 divied by 5 and got $6.80.
