the ratio of picnic tables to garbage cans in a new national park should be 5:2. the park design shows plans for 30 picnic tables in a small campground and 110 picnic tables in a large camp ground how many garbage cans should there be in each campground
Answers
Answer:
Small campground = 12 garbage cans
Large campground = 44 garbage cans
Step-by-step explanation:
Picnic tables : garbage cans
= 5 : 2
Small campground = Picnic tables : garbage cans
= 30 : x
5 : 2 = 30 : x
5/2 = 30/x
Cross product
5 * x = 2 * 30
5x = 60
x = 60/5
= 12
5 : 2 = 30 : 12
large camp ground = Picnic tables : garbage cans
5 : 2 = 110 : x
5/2 = 110/x
Cross product
5 * x = 2 * 110
5x = 220
x = 220/5
= 44
5 : 2 = 110 : 44
Therefore, there are 12 garage cans in the small campground and 44 garbage cans in the large campground
Mr. Drew wants to build a square sandbox for his children. The area of the sandbox will be 104 ft2. To the nearest tenth, what is the total length of Mr. Drew wants to build a square sandbox for his children. The area of the sandbox will be 104 ft2. To the nearest tenth, what is the total length of wood Mr.drew needs to make the sides of the sandbox
Answers
Answer:
26 ft.2
Step-by-step explanation
Divide 104 by 4 because the sandbox is a square. With a square all sides are equal length, so you just divide by the amount of sides.

Find a polynomial F(x) of degree 3 with real coefficients and the following zeros. 4,1-i help fast please?
Answers
Answer:
f(x) = x³ - 6x² + 10x - 8
Step-by-step explanation:
Complex zeros occur as conjugate pairs, thus
Given x = 1 - i is a zero then x = 1 + i is also a zero
Given the zeros are
x = 4, x = 1 - i, x = 1 + i then the corresponding factors are
(x - 4), (x - (1 - i) ), (x - (1 + i ) ), that is
(x + 4), ( x - 1 + i), (x - 1 - i)
f(x) is then the product of the factors, that is
f(x) = (x - 4)((x - 1) + i)((x - 1) - i ) ← distribute the complex factors
= (x - 4)((x - 1)² - i² ) → i² = - 1
= (x - 4)(x² - 2x + 1 + 1)
= (x - 4)(x² - 2x + 2) ← distribute
= x³ - 2x² + 2x - 4x² + 8x - 8 ← collect like term
f(x) = x³ - 6x² + 10x - 8
The required polynomial is f(x) = x³ - 6x² + 10x - 8 which has a degree is 3 with real coefficients.
What is a polynomial?A polynomial is defined as a mathematical expression that has a minimum of two terms containing variables or numbers.
The required polynomial F(x) of degree 3 with real coefficients and the following zeros. 4, 1-i
This means i.e.
x = 4, x = 1 - i, and x = 1 + i
As per the fundamental of algebra, the corresponding factors are (x - 4), (x - (1 - i) ), (x - (1 + i ) ),
The factors are (x + 4), ( x - 1 + i), and (x - 1 - i)
If the above corresponding factors are multiplied then we can find f(x)
f(x) = (x - 4)((x - 1) + i)((x - 1) - i )
f(x) = (x - 4)((x - 1)² - i² ) → i² = - 1
f(x) = (x - 4)(x² - 2x + 1 + 1)
f(x) = (x - 4)(x² - 2x + 2)
f(x) = x³ - 2x² + 2x - 4x² + 8x - 8
f(x) = x³ - 6x² + 10x - 8
Thus, the required polynomial is f(x) = x³ - 6x² + 10x - 8.

Answer:
For #21, x = 35, y = 85
Step-by-step explanation:
For these types of problems, you will simply use to facts. The sum of the measure of a line is 180 degrees, and alternate angles of crossing lines are equivalent. With that being said, let's work #21.
We can see that there are two lines, and we are given 2 values to find with 3 possible equations.
[1] ( 2x + 25 ) + y = 180
[2] y + ( 3x - 10 ) = 180
[3] 2x + 25 = 3x - 10
Using any of these equations, we can solve for the variables. Let's use the 1st and 3rd equations to find x and y.
2x + 25 = 3x - 10
2x + -2x + 25 + 10 = 3x + -2x + -10 + 10
35 = x
Now plug in the value of x to find y:
( 2x + 25 ) + y = 180
( 2(35) + 25 ) + y = 180
( 70 + 25 ) + y = 180
95 + y = 180
y = 85
We can check these values by plugging into the 2nd equation
x = 35 ; y = 85
y + ( 3x - 10 ) = 180
(85) + (3(35) - 10) = 180
85 + ( 105 - 10) = 180
85 + 95 = 180
180 = 180
Thus, we have validated our results and found the values of x and y.
Cheers.

earned $155 in interest. How much had Mr. Y invested
in the account paying 7%?
Answers
Answer:
He invested approximately $2,215
Step-by-step explanation:
Mr Y invested $2000 in two accounts.
One pays 7%, and the other pays 5%.
At the end of one year, Mr Y earned $155 in interest. We want to know how much Mr Y invested in the account paying 7%.
Let the amount he invested be X, then
7% of X = 155
(7/100)X = 155
0.07X = 155
X = 155/0.07
= 2,215
He invested approximately $2,215
