6. Find the perimeter (distance around) each of the foundations in Figure1 and 2.
a. Foundation A perimeter=_________feet
b. Foundation B perimeter=_________feet

Answer:

7.1x + 6.6

Step-by-step explanation:

In order to subtract these two polynomials, you first have to change all the signs in the second parenthesis. Now you should have:

(2.1x + 2.6) - (5x + 4).

Next if you are subtracting vertically (it's easier this way, if you do) line up the like terms, like so⤵⤵⤵:

2.1x + 2.6

+ 5x + 4

7.1x + 6.6

Answer:

Length: 5 ft; width: 4 ft.

Step-by-step explanation:

A = LW     formula for area of rectangle

(2x + 1)(2x) = 20      substitute length, width, and area into formula

4x² + 2x - 20 = 0      use the distributive property to multiply out left side

2x² + x - 10 = 0         divide both sides of equation by 2

(2x + 5)(x - 2) = 0        factor out trinomial

2x + 5 = 0  or  x - 2 = 0        use zero product rule to solve for x

2x = -5  or x = 2       subtract 5 from both sides; add 2 to both sides

x = -5/2  or  x = 2

We discard x = -5/2 since it would give negative length and width, and the length and width cannot be negative.

Length: 2x + 1 = 2(2) + 1 = 5

Width: 2x = 2(2) = 4

Length: 5 ft; width: 4 ft.

Answer:

The equation of a line is written in the form y=mx+b. “m” is the slope and “b” is the y-intercept. To find the slope, use the distance formula. The distance formula is Y2-Y1/X2-X1. You can use any two points on the graph but I will use (0,4) and (3,6).

6-4/3-0

2/3

The slope is 2/3. To find the y-intercept, look at the graph and find the where the line crosses the y-axis. The y-intercept in 4. So, the equation of this line is y=2/3x+4.

Answer:

[tex]y=\boxed{\dfrac{2}{3}}\:\:x+\boxed{4}[/tex]

Step-by-step explanation:

Slope-intercept form of a linear equation:

  [tex]y = mx + b[/tex]

where:

To find the slope of the given line, define two points on the line:

Substitute the two defined points into the slope formula and solve for m:

[tex]\implies \textsf{slope}\:(m)=\dfrac{4-0}{0-(-6)}=\dfrac{4}{6}=\dfrac{2}{3}[/tex]

The y-intercept is y-value of the point at which the lines crosses the y-axis.  From inspection of the graph, the y-intercept is 4.

Therefore, substitute the found slope and y-intercept into the slope-intercept formula to create the equation of the given line:

[tex]\implies y=\dfrac{2}{3}x+4[/tex]

Answer:

C. y=-3x+2

Step-by-step explanation:

Looking at the graph, we see that the line intercepts the y axis at 2 and is decreasing as x increases.

The formula for a linear equation is y=mx+b

where b is the y intercept, which in this case is 2

since the y values decreases as x increases, m must be negative

Answer:

147 hummingbirds are in the sanctuary.

Step-by-step explanation:

The answer can be found using the given percentage. Stating that 35% of the birds in the sanctuary are hummingbirds means that the amount of hummingbirds is 0.35 times the total amount of birds.

[tex]420 \: \times \: 0.35 \: = 147[/tex]

Percentages can always be converted to a decimal number:

(1% = 0.01 ; 10% = 0.10 ; 100% = 1.00; etc.)

Answer:

[tex]u_{n}[/tex] = - 5.6n + 3.2

Step-by-step explanation:

The explicit formula for an arithmetic sequence is

[tex]u_{n}[/tex] = u₁ + (n - 1)d

where u₁ is the first term and d the common difference

To find u₁ use the given recursive formula

u₁ = u₀ - 5.6 = 3.2 - 5.6 = - 2.4

from the recursive formula d = - 5.6 , then explicit formula is

[tex]u_{n}[/tex] = - 2.4 - 5.6(n - 1) = - 2.4 - 5.6n + 5.6 = - 5.6n + 3.2

Answer:

9 fish

Step-by-step explanation:

If each fish costs 4 dollars, and we can spend at most 36 dollars, we can find out that we can buy 9 fish by dividing 36/4, which gives you the answer of 9.

We can model this problem by doing

4x = 36

Divide by 4 on both sides to isolate the x

x = 9

Answer:

4x ≤ 36

x ≤ 9

1 2 and 1/3 least common denominator

What is the least common denominator? LCD in math

The LCD of 1/2 and 1/3 is 6, because LCM(2, 3) = 6;

Knowing the LCD, you can find equivalent fractions to yours 1/2 and 1/3, with the denominator equal to found LCD:

Answer:

12.

Step-by-step explanation:

One way to find the LCD is from the prime factors:

4 =  2*2

6 = 2*3

One '2' occurs in both sets, so we only include one of these 2's, so the LCD

= 2*2*3

= 12.

Answer:

5 miles

Step-by-step explanation:

Answer:

To write the equatipn without any fractions, multiply by a common denominator. The common denominator between 3 and 5 is 15.

15(2/3x-3)=15(2/5)

10x-45=6

So, the rewritten equation is 10x-45=6.
