You want to surround the perimeter of a garden with 35 stones. You need to place a certain number of large and small stones, and for every large
stone, you want to use 4 small stones. Choose the correct equation to find the number of stones for each size. Then solve the equation
OAX + 4x = 35,7 large stones and 28 small stones
O B. X+5x = 35, 7 large stones and 28 small stones
O cx + 4 = 35, 4 large stones and 31 small stones
D. 4x = 35 + x 12 large stones and 23 small stones
Answer: A) x + 4x = 35; 7 large stones and 28 small stones
======================================================
Explanation:
x = number of large stones
4x = number of small stones
x+4x = total number of stones = 35
x+4x = 35 is the equation to solve
-----------
Let's isolate x
x+4x = 35
5x = 35
x = 35/5
x = 7 large stones are needed
4x = 4*7 = 28 small stones are needed

The area is square feet of a rectangular garden can be expressed as the product of the garden's length and
width, or A(x) = 2x2 - 21x + 40. If the width of the garden is (x - 8) feet, what is the length of the garden?
Answer:
(2x-5)feet
Step-by-step explanation:
The area of the rectangular garden A = Length × Width
Given the area A(x) = 2x² - 21x + 40
And the width =x-8 feet
To get the length, we will simply factorise the area function as shown;
You will just factorise the area
Factorizing 2x² - 21x+40
2x² − 21x + 40
2x² -16x - 5x + 40
2x(x - 8) -5(x - 8)
=(2x−5)(x−8)
Hence the length of the garden is
(2x-5)feet
Henry can paint a small house in 3 days, Ruby can paint a small house in 4 days, and Charlie can paint a small house in 5 days. How long will it take for Henry, Ruby and Charlie to paint one small house together? Give your answer as a fraction.
Answer:
So it will take them 1 day 6 hours and 39 minutes to paint one small house.
Step-by-step explanation:
Henry can paint 1 small house in 3 days so he can paint 1/3 or .3333 in a day
Ruby can paint 1 small house in 4 days so she can paint 1/4 or .25 in a day
Charlie can paint 1 small house in 5 days so he can paint 1/5 or .2 in a day
Together, that means they pain .3333 + .25 + .2 of a house per day. That's an daily rate of:
.3333 + .25 + .2 = .78333
The portion of the house they clean in x days is .78333x. We'd like to know how long it will take them to paint 100% or 1 of the house. So:
.78333x = 1 Divide each side by .78333
x = 1/.78333
x ≈ 1.277
Let's convert .277 to hours by multiplying by 24
.277 * 24 = 6.65
Let's convert .65 to minutes by multiplying by 60
.65 * 60 = 39
So it will take them 1 day 6 hours and 39 minutes to paint one small house.
Answer:
1.277 days
Step-by-step explanation:
H paint .3333 a day R paint .25 a day Charlie paint .2 a day
.3333 + .25 + .2 = .78333
x is number of days to paint.
.78333x = 1
x = 1/.78333 = 1.277
1.277 days

Lena's earnings for 19 hours: I dollars
Answer:
[tex]E = 30 \times H[/tex]

Step-by-step explanation:
Given that:
For each hour of tutoring, Lena earns 30 dollars.
E is her earning and
H is the number of hours for which she tutors.
To find:
Equation relating E to H.
Solution:
Let Lena tutors for 1 hour, then the earning = 30 dollars
Let Lena tutors for 2 hours, then the earning = 30+30 OR 2[tex]\times[/tex]30 = 60 dollars
Let Lena tutors for 3 hours, then the earning = 30+30 +30 OR 3[tex]\times[/tex]30 = 90 dollars
If Lena tutors for H number of hours, then the earning, E = 30 + 30 + .... + 30 (H times) i.e.
[tex]E = 30 \times H[/tex]
So, the equation that relates E to H is given as:
[tex]E = 30 \times H[/tex]
Now, it is given that she tutors for 19 hours.
Let us put H = 19 hours in the above equation:
[tex]E = 30 \times 19 \\\Rightarrow E = \$570[/tex]
Therefore, the earning for 19 hours of tutoring is 570 Dollars.

If you deposit $200 into a CD (Certificate of Deposit) with an interest rate of 1% for 3 years, how much simple interest will you earn after
THREE years?
O $1
$5
$6
$25
Answer:
$6
Step-by-step explanation:
A=P(1+i.n)
A=200(1+0.01.x 3)
A=206
Thus 206 - 200 = $6
You will earn $6 in interest.
The interest you will earn per year is:
= Interest rate x Amount deposited
= 200 x 1%
= $2
Because it is simple interest, you will earn the same amount of interest every year. In 3 years you will have:
= Interest per year x number of years
= 2 x 3
= $6
You will therefore earn $6 in interest.

A map is created on the coordinate plan, lori's house is located at ( -3, 7) and Andreas house is located at (-3,-4). Each unit on the map represents 0.2 mile.
Answer: 2.2 miles.
Step-by-step explanation:
I guess that we want to find the distance between Lori's and Andrea's houses.
First, we have the locations:
L = (-3, 7)
A = (-3. -4)
To find the distance (in units) between two coordinate points (a1, a2) and (b1 b2) we can use the formula:
Distance = I (a1, a2) - (b1, b2)I = √( (a1 - b1)^2 + (a2 - b2)^2)
Then in this case we have that:
Distance = √( ( -3 -(-3))^2 + (7 - (-4))^2) = √( 0 + 11^2) = 11
The distance between their houses is 11 units.
And we know that each unit represents 0.2 miles, then 11 units represent 11 times that amount, the distance in miles will be:
D = 11*0.2 miles = 2.2 miles.

Rectangle with width labeled on the right, width equals 4 and 1 over 2 inches. Below the rectangle, it says, length equals question mark. Inside the rectangle, it says area equals 36 and 3 over 4 square inches.
Answer:
length = [tex]8\frac{1}{6}[/tex] inches
Step-by-step explanation:
A rectangle is a quadrilateral which has opposite sides to be equal.
Area of a rectangle = length × width
Given that: Area = [tex]36\frac{3}{4}[/tex] square inches, width = [tex]4\frac{1}{2}[/tex] inches, length = l. Thus;
[tex]36\frac{3}{4}[/tex] = l × [tex]4\frac{1}{2}[/tex]
[tex]\frac{147}{4}[/tex] = l × [tex]\frac{9}{2}[/tex]
divide both sides by [tex]\frac{9}{2}[/tex],
l = [tex]\frac{147}{4}[/tex] ÷ [tex]\frac{9}{2}[/tex]
= [tex]\frac{147}{4}[/tex] x [tex]\frac{2}{9}[/tex]
= [tex]\frac{49}{6}[/tex]
l = [tex]8\frac{1}{6}[/tex]
Therefore, the length of the rectangle is [tex]8\frac{1}{6}[/tex] inches.
Emilio throws a marshmallow into the air from his balcony. The height of the marshmallow (in feet) is represented by the equation h=−16(t−14)2+49, where t is the time (in seconds) after he throws the marshmallow. What is the maximum height of the marshmallow? Enter your answer as the correct value, including units, like this: 42 meters Be sure to use the correct units from the context of the problem.
Answer:
49 ft
Step-by-step explanation:
h=−16(t−14)^2+49
The path of the marshmallow is an inverted parabola. It has symmetry with respect to its vertical axis.
We take the derivative of the height function.
dh/dt = -32(t - 14)
dh/dt = -32t + 448
We set the derivative equal to zero ti find the value of t corresponding to a maximum value of h.
-32t + 448 = 0
-32t = -448
t = 14
Maximum height occurs at t = 14 seconds.
h=−16(t−14)^2+49
t = 14
h=−16(14−14)^2+49
h = 49
Maximum height is 49 feet.
Raphael's Gym has a climbing wall that starts at the gyms basement, 9 feet above the ground level. The wall extends to 21 feet above the ground level. what is the total height of the climbing wall? Represent this situation with a number. Then, explain your answer.
Answer:
The total height of the climbing wall is 12 feet
Step-by-step explanation:
The given parameters are;
The star of the climbing wall = On the gym basement
The height of the gym's basement above the ground level = 9 feet
The height to which the wall extends above the ground level = 21 feet
The total height of climbing the wall = 21 - 9 = 12 feet
The start of the climbing wall is at the gym's basement level which is already 9 feet above the ground level, therefore, given the the height of the wall is 21 feet above ground level, with wall situated already at 9 feet above ground level which gives the total height of the climbing wall will be 21 - 9 feet or 12 feet.
