there are 8 knives and 12 forks in a package of plastic utensils. Which ratio is equivelent to 8/12?

Answer:

width is 47 and the length is 90

Step-by-step explanation:

Hello!

You find the perimeter by adding all the sides

l + l + w + w = p

The perimeter is 274

l + l + w + w = 274

It says the length is 4 less than double the width

l = 2w - 4

We can put this into the original equation

2w - 4 + 2w - 4 + w + w = 274

Now we solve

Combine like terms

6w - 8 = 274

Add 8 to both sides

6w = 282

Divide both sides by 6

w = 47

We can put w into the orginal equation to find l

l + l + 47 + 47 = 274

Combine like terms

2l + 94 = 274

Subtract 94 from both sides

2l = 180

Divide both sides by 2

l = 90

The answer is the width is 47 and the length is 90

Hope this helps!

Answer:

lenght: 90 yards

width: 47 yards

Step-by-step explanation:

perimeter = 2(length + width)

274 = 2(h + w)

h = 2w - 4

h = length

w = width

then:

274 = 2((2w-4) + w)

274/2 = 2w - 4 + w

137 = 3w - 4

137 + 4 = 3w

141 = 3w

w= 141/3

w = 47 yd

h = 2w - 4

h = 2*47  - 4

h = 94 - 4

h = 90 yd

probe:

274 = 2(47 + 90)

274 = 2(137)

Answer:

Step-by-step explanation:

1 pound of raisins = $2

1 pound of almonds = $5

Let the number of raisins be represented by a

Let the number of almonds be represented by b

We are told in the question that:

Six pounds of a trail mix contains 2 more pounds of raisins than almonds.

a + b = 6 pounds

Hence, Almonds = 2 pounds

Raisins = 4 pounds

The cost of the 6 pounds of trail mix

= 4 × $2 + 2 × $5

=$8 + $10

= $18

  d = √((x2 -x1)^2 +(y2 -y1)^2) = √((-3-6)^2 +(-2-2)^2) = √(81 +16) = √97

The distance between the points is √97 ≈ 9.85 units.

Answer:

The amount each took home was 20 unit currency.

Step-by-step explanation:

We are given that Seven apple women, possessing respectively 20, 40, 60, 80, 100, 120, and 140  apples, went to market and sold all their apples at the same price, and each  received the same sum of money.

Formula  : [tex]a \times n + (n - 1)[/tex], [tex](a + b)\cdot n + (n - 2)[/tex], [tex](a + 2 \cdot b) \cdot n + (n - 3)[/tex], [tex](a + 3 \cdot b) \cdot n + (n - 4)[/tex], [tex](a + 4 \cdot b) \cdot n + (n - 5)[/tex], [tex](a + 5 \cdot b) \cdot n + (n - 6)[/tex], [tex](a + 6 \cdot b) \cdot n + (n - 7)[/tex]

[tex]a \cdot n + (n - 1) = 20[/tex]

[tex](a + b) \cdot n + (n - 2)=40[/tex]

[tex](a + 2 \cdot b) \cdot n + (n - 3) = 60[/tex]

[tex](a + 3 \cdot b) \cdot n + (n - 4) = 80[/tex]

[tex](a + 4 \cdot b) \cdot n + (n - 5) = 100[/tex]

[tex](a + 5 \cdot b) \cdot n + (n - 6) = 120[/tex]

[tex](a + 6 \cdot b) \cdot n + (n - 7) = 140[/tex]

On solving :

n = 7, a = 2, b = 3

So,

[tex]2 \times 7 + 6 = 20[/tex]

[tex]5 \times 7 + 5=40[/tex]

[tex]8 \times 7 + 4 = 60[/tex]

[tex]11 \times 7 + 3 = 80[/tex]

[tex]14 \times 7 + 2 = 100[/tex]

[tex]17 \times 7 + 1 = 120[/tex]

Based on market pricing if groups of apples are sold at 1 unit currency for 7, and extras are sold for 3 unit currency per extra 1, we have the amount :

2×1 + 6×3 = 20

5×1 + 5×3=20

8×1 + 4×3 = 20

11×1 +  3×3 = 20

14×1 + 2×3 = 20

17×1 + 1×3 = 20

20×1 = 20

Therefore, the amount each took home was 20 unit currency.

Answer:

B

Step-by-step explanation:

Given

3(- n + 4) + 5n = 2n ← distribute and simplify left side

- 3n + 12 + 5n = 2n

2n + 12 = 2n ( subtract 12 from both sides )

2n = 2n - 12 ( subtract 2n from both sides )

0 = - 12 ← not possible

This indicates the equation has no solution

Comparing the types of solutions

A n = 3

Indicates that there is only one unique solution to the equation.

B no solutions

This is indicated when you solve and obtain a ridiculous statement, similar to the one obtained in part A, that is

0 = 12

Answer:

height =  h = 13.4 cm

volume =  V = 602.8 cm³

Step-by-step explanation:

area of a square base = 15 cm x 9 cm = 135 cm²

slant height of pyramid = 16m

solving height:   (see attached image)

first step is to take the diagonal base:

side of base 15 =  15 / 2 = 7.5cm

side of base 9 = 9 / 2 = 4.5m

diagonal base = sqrt ( 7.5² + 4.5²) = 8.75 cm

therefore

height² = slant height² - diagonal base²

h² = 16² - 8.75²

h = 13.4 cm

solving the volume:

V = 1/3 * area of square base * h

V = 1/3 * 135 * 13.4

V = 602.8 cm³

Answer:

w = V / lh

Step-by-step explanation:

V = ℓwh

Where,

V=volume of a rectangular prism

l= length of the rectangular prism

w= width of the rectangular prism

h= height of the rectangular prism

Rearrange the quantities in this formula to give a new formula for the width of the rectangular prism.

V = ℓwh

It can be written as

V = l * w * h

w = V ÷ l * h

= V / lh

w = V / lh

Width of a triangular prism equals Volume of the rectangular prism divided by length of the rectangular prism times height

Question: Given that BE bisects ∠CEA, which statements must be true? Select THREE options.

(See attachment below for the figure)

m∠CEA = 90°

m∠CEF = m∠CEA + m∠BEF

m∠CEB = 2(m∠CEA)

∠CEF is a straight angle.

∠AEF is a right angle.

Answer:

m∠CEA = 90°

∠CEF is a straight angle.

∠AEF is a right angle

Step-by-step explanation:

Line AE is perpendicular to line CF, which is a straight line. This creates two right angles, <CEA and <AEF.

Angle on a straight line = 180°. Therefore, m<CEA + m<AEF = m<CEF. Each right angle measures 90°.

Thus, the three statements that must be TRUE are:

m∠CEA = 90°

∠CEF is a straight angle.

∠AEF is a right angle

The correct statements from the given diagram is m∠CEA = 90°, m∠CEF = m∠CEA + m∠BEF and m∠CEB = 2(m∠CEA)

From the given diagram, we have the following information

∠CEF is a straight angle.

∠AEF is a right angle.

Line AE is perpendicular to line CF, which is a straight line. This creates two right angles, <CEA and <AEF.

Since the angle on a straight line is 180 degrees, hence;

<CEA + m<AEF = m<CEF

Hence, the three statements that must be TRUE are m∠CEA = 90°, ∠CEF is a straight angle and ∠AEF is a right angle

Answer:

B.   183 degrees.

Step-by-step explanation:

m arc MN = 360 - 107 - 177

= 360 - 284

= 76

m NMK =   76 + 107

= 183

The measure of the arc NMK will be 183°. Then the correct option is B.

The circle is at equidistant of points drawn from the center. The radius of a circle is the distance between the center and the circumference.

The measure of the angle ∠MLK is 35°.

The major and minor arc is 117x and 107x.

We know that the angle ∠MLK is the half of the difference of the major arc to minor arc.

∠MLK = (arc KN – arc KM) / 2

    35° = (177x - 107x) / 2

    70° = 70x

        x = 1°

Then the measure of the arc KN will be

Arc NK = 177 x 1

Arc NK = 177°

We know that the sum of the arc KN and KMN will be 360°.

mNK + mNMK = 360°

 177° + mNMK = 360°

           mNMK = 360° – 177°

           mNMK = 183°

The measure of the arc NMK will be 183°.

Then the correct option is B.

Answer:

The answer is 24

Step-by-step explanation:

If the restaurant fee is $7.5 and the price is $14 per pizza, she has $52.5 to spend on the pizzas after we deduct the restaurant fee.

That means she can get 52.5 / 14 = 3.75 pizzas.

I hope this answer helps.

The total slices she can afford is 30 and this can be determined by using the unitary method and forming the linear equation.

Given :

The following steps can be used to determine the total slices she can afford:

Step 1 - Total cost to order one pizza is given by:

= 7.5 + 14

= $21.5

Step 2 - Let the total number of pizzas she can order be 'x'. So, the delivery fee plus the cost of the pizzas under $60 is represented by the equation:

14x + 7.5 = 60

14x = 52.5

x = 3.75

Step 3 - Now, according to the given data if one pizza contains 8 slices then 3.75 pizza contains:

[tex]= 3.75\times 8[/tex]

= 30 slices

The total slices she can afford is 30.

Step-by-step explanation:

Marissa has a Master's degree and earns annual salary of $80,400.

She works 40 hours per week for 48 weeks per year.

Her sister has a Bachelor's degree and earns an average of $58,000 per year.

She works 40 hours per week for 52 weeks per years.

Marissa works for a total of 40 × 48 = 1920 hours a year.

Her hourly wage = [tex]\frac{80,400}{1920}[/tex] = $42 (rounded up to nearest dollar).

Her sister works for a total of 40 × 52 = 2080 hours

Her hourly wage = [tex]\frac{58,000}{2080}[/tex] = $28 (rounded up to nearest dollar)

So Marissa's hourly wage is $42 - $28 = $14 more than her sister's hourly wage.

Answer:

The amount Trevor's family pay per minute on shower water is $0.005.

Step-by-step explanation:

The cost of water is,

Cost = $0.20/liter

Amount of water used over the entire month:

Amount of water used = 72 liters

Compute the total water cost as follows:

Total water cost = Amount of water used × Cost

                           = 72 × 0.20

                           = $14.4/liter

The average number of minutes each person showered is:

Average number of minutes = 480 minutes.

The number of people in Trevor's house:

N = 6

Compute the total amount of time the 6 person showered as follows:

Total amount of time = Average number of minutes × N

                                   = 480 × 6

                                   = 2880 minutes

Compute the pay per minute on shower water as follows:

Pay per minute on water = Total water cost ÷ Total amount of time

                                          = $14.4 ÷ 2880

                                          = $0.005

Thus, the amount Trevor's family pay per minute on shower water is $0.005.
