Answer:

  7 1/8 yd

Step-by-step explanation:

The perimeter is the sum of the three side lengths. They are all the same, so we can use multiplication to find their sum.

  P = 3·(2 3/8 yd) = 6 9/8 yd  . . . . .  9/8 = 1 1/8

  P = 7 1/8 yd

The perimeter is 7 1/8 yards.

Answer:

[tex]perimeter \: of \: the \: triangle \\ = 2 \frac{3}{8} +2\frac{3}{8} + 2 \frac{3}{8} \\ = 3 \times 2 \frac{3}{8}\\= 3 \times \frac{19}{8} \\ = \frac{57}{8} \: yd \\ = 7 \frac{1}{8} \: yd[/tex]

Answer:

Jane spend 4 hours in a day sleeping, and 28 hours in a week.

Step-by-step explanation:

In 1 day, there are 24 hours. 24 multiplied by 1/6 is 4. I know this because 24 x 1/6 = 24/1 x 1/6 = 24/6 = 4/1 = 4.

In 1 week, there are 168 hours. 1/6 multiplied by 168 is 28. I know this because 168 x 1/6 = 168/1 x 1/6 = 168/6 = 28/1 = 28

Answer:

Let's solve for f.

x=5+4(x−4)f(7)

Step 1: Flip the equation.

28fx−112f+5=x

Step 2: Add -5 to both sides.

28fx−112f+5+−5=x+−5

28fx−112f=x−5

Step 3: Factor out variable f.

f(28x−112)=x−5

Step 4: Divide both sides by 28x-112.

f(28x−112)28x−112=x−528x−112

f=x−528x−112

Answer:

f=x−528x−112

Answer:

$113.90

Step-by-step explanation:

Find the cost of the meal with sales tax:

90 x 0.075 = 6.525

Add that to the original cost of the meal:

90 +  6.525 = 96.525

Find the cost of the tip:

96.525 x 0.18 = 17.3745

Add the tip to the meal price:

96.525 + 17.3745 = 113.8995

The solution is Option G.

The value of the equation A = ( 2/3 ) x 15% x $ 2000 = $ 200

Equations are mathematical statements with two algebraic expressions flanking the equals (=) sign on either side.

It demonstrates the equality of the relationship between the expressions printed on the left and right sides.

Coefficients, variables, operators, constants, terms, expressions, and the equal to sign are some of the components of an equation. The "=" sign and terms on both sides must always be present when writing an equation.

Given data ,

Let the equation be represented as A

Now , the value of A is

Substituting the values in the equation , we get

A = ( 2/3 ) x 15% x 2000   be equation (1)

On simplifying the equation , we get

A = ( 2/3 ) x ( 15/100 ) x 2000

A = ( 2/3 ) x ( 15 ) x ( 20 )

On further simplification , we get

A = ( 2/3 ) x 300

A = 2 x 100

A = $ 200

Therefore , the value of A is $ 200

Hence , the equation is A = $ 200

Answer:

y less than or equal to 2x+1

Step-by-step explanation:

Move the slope to the other side and cancel the 4 on the y to get only y. Whatever you do on one side you must do on the other.

Answer:

y≤2x+1

Step-by-step explanation:

slope intercept form= y=mx+b

-8x+4y<=4

-8x+4y≤4

Add 8x to both sides

4y≤8x+4

Divide both sides by 4.

y≤2x+1

Answer: $14160

Step-by-step explanation:

Simple interest would be calculated as:

= PRT/100

where,

P = Principal = $12000

R = Rate = 6%

T = Time = 3 years

Simple interest = ($12000 × 6 × 3)/100

= $216000/100

= $2160

The amount that Tobias owe in all would be:

= $12000 + $2160

= $14160

Step-by-step explanation:

Answer:

0.172 ; 0.0884 ; 0.9115

Step-by-step explanation:

Proportion or those who feel secure, p = 0.45

Sample size, n = 8

Using the binomial distribution formula :

P(x =x) = nCx * p^x * (1 - p)^(n - x)

A.) p(x = 5)

P(x =5) = 8C5 * 0.45^5 * 0.55^3

P(x = 5) = 56 * 0.0184528125 * 0.166375

P(x = 5) = 0.1719248540625

P(x = 5) = 0.172

B.) P(x > 5)

P(x > 5) = P(x = 6) + P(x = 7) + P(x = 8)

P(x > 5) = 0.0703 + 0.0164 + 0.0017

P(x > 5) = 0.0884

C.) P( ≤ 5) = P(x = 0) + P(x = 1) + P(x = 2) + P(x = 3) + P(x = 4) + P(x = 5)

Using the binomial probability calculator to obtain a direct solution :

P( ≤ 5) = 0.9115

Answer: x=11 or x=-11

Step-by-step explanation:

Answer:x=11 or x=-11

Step-by-step explanation:  First, Use the FOIL method.

(x+5)(x+4)=9x+141

First: [tex]x^{2}[/tex]

Outer: 4x

Inner:  5x

Last:  5x4=20

Combine Like terms and write in standard form: [tex]x^{2}[/tex]+9x+20

Set up new equation:[tex]x^{2}[/tex]+9x+20=9x+141

Subtract 9x from both sides: [tex]x^{2}[/tex]+20=141

Subtact 20 from both sides: [tex]x^{2}[/tex]=121

Sqr root 121: [tex]\sqrt{121}[/tex] =11

Remeber a sqr root of a positive number can be positive and negative so x= 11 or -11
