Step-by-step explanation:

Answer:

$18

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

Three more than nine times a number is at least five times the number.

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

Answer:

$14

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.

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:

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.

=================================================

Explanation:

Sine is given to be negative, and so is tangent. This only happens in quadrant Q4

Recall that y = sin(theta), so if sin(theta) < 0, then we're below the x axis.

If tan(theta) < 0, then this means cos(theta) > 0

So we have y < 0 and x > 0 which places the angle somewhere in Q4.

--------------------------

Draw a right triangle as shown below in the attached image. We have AC = 25 and BC = 7. Use the pythagorean theorem to find that AB = 24

So this is what your steps may look like

a^2+b^2 = c^2

7^2+b^2 = 25^2

b^2+49 = 625

b^2 = 625-49

b^2 = 576

b = sqrt(576)

b = 24

So because AB = 24, we know that the cosine of the angle is adjacent/hypotenuse = 24/25

---------------------------

As an alternative, you could use the trig identity

sin^2(x) + cos^2(x) = 1

and plug in the given value of sine to solve for cosine. The cosine value result will be positive since we're in Q4.

So,

sin^2(x) + cos^2(x) = 1

(-7/25)^2 + cos^2(x) = 1

(49/625) + cos^2(x) = 1

cos^2(x) = 1 - (49/625)

cos^2(x) = (625/625) - (49/625)

cos^2(x) = (625-49)/625

cos^2(x) = 576/625

cos(x) = sqrt(576/625)

cos(x) = sqrt(576)/sqrt(625)

cos(x) = 24/25

This is effectively a rephrasing of the previous section since the pythagorean trig identity is more or less the pythagorean theorem (just in a trig form)

Step-by-step explanation:

Since, the hiker are walking at different speeds they meet at a point not in the middle.

Let distance travelled by Hiker A (slower) be x at speed s.

So, distance travelled by Hiker B (faster) is (22 - x) at a speed (s + 1.1) .

[tex]speed \: = \frac{distance}{time} [/tex]

Solving equations 1 and 2, we get :

x = 8.8m and s = 2.2mph

Therefore,

Speed of Hiker A = 2.2 mph

Speed of Hiker A = 2.2 mphSpeed of Hiker B = 3.3 mph

Ally sliced 32 kg of watermelon for a party. She divided the watermelon slices equally between 8 large bowls.

How many grams of watermelon did Ally put in each bowl?

Answer:

4000g

Step-by-step explanation:

Given the following :

Mass of water melon sliced = 32kg

Number of bowls water melon was shared equally in = 8

Therefore, mass of water melon on each bowl :

Mass of water melon / number of bowls

= 32kg / 8

= 4kg

Answer:

Step-by-step explanation:

a) The cost of a product is given as:

Cost = a + bx

Where a is the fixed cost, b is the variable cost, x is the independent variable.

In this case, the independent variable is the distance(d), therefore:

Cost (C) = a + bd

C = a + bd

But the variable cost is $10/km, therefore:

C = a + 10d

A 2.5 km trip cost $40, therefore:

40 = a + 10(2.5)

40 = a + 25

a = 40 - 25 = 15

The fixed cost is $15. Therefore the equation for cost is:

C = 15 + 10d  

b) C = 15 + 10d  

For 6.5 km ride:

C = 15 + 10(6.5) = 15 + 65 = 80

It would cost $80 for a 6.5 km drive.

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
