Answer:
40 ft by 70 ft
Step-by-step explanation:
The 50 ft side of the house can add to the total perimeter of the play area, allowing it to be 170+50 = 220 feet. Then the sum of length and width will be half that, or 110 feet.
Factors of 2800 that have a sum of 110 are 40 and 70.
The play area fence can extend 10 ft either side of the house, out 40 ft, then 70 ft across the back, for a total length of 170 ft. Dimensions of the play area are 40 ft by 70 ft.

Answer:
56
Step-by-step explanation:
By tracing the lines on the tree diagram, we see the probability of both being red is 0.5 × 0.6 = 0.3.
The probability of both being blue is 0.5 × 0.4 = 0.2.
So we would expect to get both blue 2/3 of the times we get both red.
X = 2/3 (84)
X = 56

While flying a kite, 400 ft of string was let out. The string ,when pulled tight, formed a 40 angle with the ground .What was the approximate height of the kite
Answer:
257 ft
Step-by-step explanation:
You know based upon soh that sin=opp/hyp
So drawing a right triangle with a hypotenuse of 400 ft and an angle of 40° with the ground, you can see that sin40=x/400
Multiply both sides to find your x value or height which is 257.

Answer:
A
120
Step-by-step explanation:
With all the parallel lines involved, the central figure is a parallelogram. These 4 sided figures have the odd property of having their opposite angles equal.
What that means, in plain English is that <NRL = <NML
Both of these angles = 120
Here's the cruncher. <NRL and <PRK are vertically opposite. They are therefore equal.
The answer to your question is 120 which is A
the answer is A good luck !
Which system of equations is represented by the graph?
Answer:
C
Step-by-step explanation:
y=x is a line that has slope 1 meaning it go ups (increases) from left to right.
So that puts us at choice A or C.
Both A or C differ by the numerator for the other function.
We can find the x-intercept for A and C by setting the numerator equal to 0 and solving for x.
Let's do that:
A: -x-10=0 C. -x+10=0
-x=10 -x=-10
x=-10 x=10
A says x-intercept -10
C says x-intercept 10
Your graph intercepts the x-axis at 10 so the answer is C.
Solve I = Prt for P when I = 5,480, r = .04, and t = 7.
Answer: P = 19,571.42857142857
Step-by-step explanation:
Plug in the variables.
5480 = x(.04)(7)
.04*7=.28
5480=.28x
.28x/.28=x
5480/.28=19,571.42857142857
19,571.42857142857(.04)(7)=5480
P = 19,571.42857142857
Answer:
19571.43
Step-by-step explanation:
We are asked to solve for P using formula [tex]I=Prt[/tex], when [tex]I=5480; r=0.04\text{ and }t=7[/tex].
Upon substituting our given values in simple interest formula, we will get:
[tex]5480=P*0.04*7[/tex]
[tex]5480=P*0.28[/tex]
Switch sides:
[tex]P*0.28=5480[/tex]
Now, we will divide both sides of our given equation by 0.28 as:
[tex]\frac{P*0.28}{0.28}=\frac{5480}{0.28}[/tex]
[tex]P=19571.42857[/tex]
[tex]P\approx 19571.43[/tex]
Therefore, the principal amount (P) is approximately 19571.43.

question is in the picture, will mark brainliest
Answer:
B
Step-by-step explanation:
h(t)=-4.9t^2+ v_0t+h_0
v_0 represents initial velocity
h_0 represents initial height
we use -4.9 for the coefficient of t^2 because we dealing with meters and seconds
(If it was feet and seconds it would have been -16 instead of -4.9)
Anyways v_0 is 15m/s (We will just put 15 to make it look less complicated)
and from the ground means the initial height was h_0=0
So the answer is B.

2^x=3^x+1 what are the exact approximate solutions
Answer:
d.
Step-by-step explanation:
The goal of course is to solve for x. Right now there are 2 of them, one on each side of the equals sign, and they are both in exponential positions. We have to get them out of that position. The way we do that is by taking the natural log of both sides. The power rule then says we can move the exponents down in front.
[tex]ln(2^x)=ln(3^{x+1})[/tex] becomes, after following the power rule:
x ln(2) = (x + 1) ln(3). We will distribute on the right side to get
x ln(2) = x ln(3) + 1 ln(3). The goal is to solve for x, so we will get both of them on the same side:
x ln(2) - x ln(3) = ln(3). We can now factor out the common x on the left to get:
x(ln2 - ln3) = ln3. The rule that "undoes" that division is the quotient rule backwards. Before that was a subtraction problem it was a division, so we put it back that way and get:
[tex]x(\frac{ln(2)}{ln(3)})=ln(3)[/tex]. We can factor out the ln from the left to simplify a bit:
[tex]x[ln(\frac{2}{3})]=ln(3)[/tex]. Divide both sides by ln(2/3) to get the x all alone:
[tex]x=\frac{ln(3)}{ln(\frac{2}{3}) }[/tex]
On your calculator, you will find that this is approximately -2.709
BRAINLIEST! It would take 4 hours to fill an aquarium using water from 10 taps.
How many hours and minutes would it take if only 6 taps were used?
Please give an explanation of your answer!
Answer:
6 hours and 40 minutes
Step-by-step explanation:
10 taps = 4 hours
( ÷ 10 ) ( × 10 )
1 taps = 40 hours
( × 6 ) ( ÷ 6 )
6 taps = 6.66666666667 hours / 400 minutes
Final answer:
To fill an aquarium initially using 10 taps in 4 hours, using 6 taps would take 6 hours and 40 minutes.
Explanation:
The time it takes to fill the aquarium initially can be calculated by:
Determine the rate of filling using all 10 taps: 1/4 of the aquarium per hour (as 4 hours to fill).
Calculate the rate using 6 taps: 6/10 of the original rate.
Divide the time taken initially (4 hours) by the reduced rate to find the new time.
Therefore, the time it would take to fill the aquarium using only 6 taps is 6.67 hours or 6 hours and 40 minutes.
PLZZZ HURRYYY!!Which graph best represents the solution to the system of equations shown below? y = -4x + 19 y = 2x + 1 A coordinate grid is shown from negative 10 to positive 10 on the x axis and also on the y axis. Two lines are shown intersecting on ordered pair 7, 3. A coordinate grid is shown from negative 10 to positive 10 on the x axis and also on the y axis. Two lines are shown intersecting on ordered pair 3, 7. A coordinate grid is shown from negative 10 to positive 10 on the x axis and also on the y axis. Two lines are shown intersecting on ordered pair negative 3, negative 7. A coordinate grid is shown from negative 10 to positive 10 on the x axis and also on the y axis. Two lines are shown intersecting on ordered pair negative 7, negative 3.
Answer:
Two lines are shown intersecting on ordered pair 3, 7.
Step-by-step explanation:
The first of the two lines has a slope of -4 and a y-intercept of 19 (off the top of the graph). It will decrease 4 units for each 1 unit to the right.
The second of the two lines has a slope of +2 and a y-intercept of +1. It will increase 2 units for each 1 unit to the right.
These two lines must intersect in the first quadrant at a point with an x-value less than 5, eliminating the first and last two choices, leaving only the second choice you have listed here.
You would have to examine the graphs to see which has the lines with proper slope and intercept.
My graphing calculator's solution is attached.

Hilda is putting new tile in an area of her home. Part of the space is rectangular with a length of 10 feet and a width of 6 feet, and part of the space is triangular with a base of
4 feet and a height of 2 feet.How many square feet of tile will Hilda need to cover the space?
Answer:
64 sq feet
Step-by-step explanation:
Given:
Rectangle Length = 10 feet
Rectangle Width = 6 feet
Triangle Base = 4 feet
Triangle Height = 2 feet
Area of rectangle = Length x Width = 10 x 6 = 60 sq feet
Area of triangle = [tex]\frac{1}{2}[/tex] x Base x Height = [tex]\frac{1}{2}[/tex] x 4 x 2 = 4 sq feet
Total area
= Area of Rectangle + Area of Triangle
= 60 + 4 = 64 sq feet
Answer:
64 ft^2
Step-by-step explanation:
The rectangular area is 10 ft by 6 ft, which comes to 60 ft².
The triangular area is A = (1/2)(base)(height) = (1/2)(4 ft)(2 ft) = 4 ft²
The total area of tile will be 4 ft² + 60 ft², or 64 ft².
Julia has saved 108 sand dollars and wants to give them away equally to x friends. Write an expression to show how many sand dollars each of Julia’s friends will receive. Then, find the total number of sand dollars each of Julia’s friends will get if Julia gives them to 12 friends.
Answer:
s = 108/x . . . . s = sand dollars each friend getseach of the 12 friends gets 9 sand dollarsStep-by-step explanation:
The point of a fraction is to express the size of something that has been divided into a number of parts equal to the denominator. For example, 1/3 represents the amount when 1 unit is divided into 3 parts.
Here, Julia has 108 that she wants to divide into x parts. The fraction 108/x will tell the size of each part.
__
When x=12, the fraction becomes 108/12 = 9/1 = 9. Each friend gets 9 sand dollars.
describe the translation y=x^2+5
Answer:
The transformation moves the graph of the function up 5 units
Step-by-step explanation:
If we have a function f(x) then the transformation
[tex]g (x) = f (x) + c[/tex] vertically shifts the graph of f(x) c units
If [tex]c> 0[/tex] the graph moves c units up
If [tex]c <0[/tex] the graph moves c units down
In this case the main function is [tex]f (x) = x ^ 2[/tex]
and [tex]g (x) = f (x) + 5 = x ^ 2 +5[/tex]
Therefore the transformation moves the graph of the function up 5 units
ANSWER
[tex]y = {x}^{2} + 5[/tex]
EXPLANATION
The given function is
[tex]y = {x}^{2} + 5[/tex]
The base of this function is
[tex]f(x) = {x}^{2} [/tex]
The translation is of the form.
[tex]y = f(x) + k[/tex]
where k is a vertical translation k units up.
[tex]y = {x}^{2} + 5[/tex]
Therefore the translation is a shift up by 5 units.

Answer:
The fraction is 7/10 and the decimal is 0.7
Step-by-step explanation:
Each incriment represents 1/10, or 0.1.
Answer:
Decimal: 0.7
Fraction: Simplified - 7/10 ; Non-simplified: 70/100
Step-by-step explanation:
There are 9 dashes in-between 0 & 1, meaning that each dash signifies 0.1, and that you are adding 0.1 each time.
The dot is located 7 dashes away from 0. Multiply 7 with 0.1
7 x 0.1 = 0.7
0.7 is your decimal answer.
Change the decimal to a fraction. To do so, move the decimal point to the right two place values and put it over 100. Add 0's if needed.
0.7 = 70/100
As it does not specify you have to simplify, put 70/100. HOWEVER, if it says you have to simplify, simplify. Divide common factors from both the numerator & denominator:
(70/100)/(10/10) = 7/10
7/10 is your simplified fraction. 70/100 is your non-simplified fraction.
