How much hot dogs was sold on Wednesday? musiclover10045, This is a question you need to answer...

Answer: Christina weighs 98 pounds.

Step-by-step explanation: The formula to solve this problem is x + 17 + x = 179, where x equals Sarah’s weight.

X + 17 + x = 179

First you need to combine the x values:

2x + 17 = 179

Next, subtract 17 from both sides:

2x = 162

Finally, divide both sides by 2:

X = 81

Sarah’s weight is 81 pounds and Christina weighs 17 pounds more, which is 98 pounds. You can double check your work by adding both of their weights (98 + 81) to make sure that your answer is correct.

Final answer:

By setting up a system of equations with the given information, we can solve for Christina's weight. Christina weighs 125 pounds.

Explanation:

To determine how much Christina weighs, we can set up an equation based on the information given. Let's define Sarah's weight as 's' and Christina's weight as 'c'. According to the question, Christina weighs 17 pounds more than twice Sarah's weight. So we can write the equation as:

c = 2s + 17

The combined weight of Christina and Sarah on the freight scale is 179 pounds. We represent this with another equation:

c + s = 179

Now we have a system of two equations:

Substituting the expression for 'c' from the first equation into the second equation gives us:

(2s + 17) + s = 179

Combining like terms, we have:

3s + 17 = 179

Moving 17 to the other side by subtracting 17 from both sides:

3s = 179 - 17

3s = 162

Dividing both sides by 3 to find Sarah's weight:

s = 162 / 3

s = 54

Now that we know Sarah weighs 54 pounds, we can find Christina's weight using the first equation:

c = 2(54) + 17

c = 108 + 17

c = 125

So, Christina weighs 125 pounds.

Step-by-step explanation:

The perimeter of a rectangle is given by the formula:

[tex]P=2l+2w[/tex]

Where l is the lenght and w is the width.

The perimeter of the original rectangle  is 88 m, then:

[tex]88=2l+2w[/tex]      [EQUATION 1]

Where l is the length of the original rectangle

 You know that if the width were doubled and the length were increased by 12 m, the perimeter would be 152 m. Therefore the new length is:

[tex]l+12[/tex]

The new width is:

[tex]2w[/tex]

Susbtitute into the equation of the perimeter and solve for w:

[tex]152=2(l+12)+2(2w)\\4w=152-(2l+24)[/tex]

 [tex]w=\frac{128-2l}{4}[/tex]      [EQUATION 2]

Substitute the Equation 2 into Equation 1 and solve for the length, as you can see below:

[tex]88=2l+2(\frac{128-2l}{4})[/tex]

[tex]88=2l+2(\frac{128-2l}{4})\\88-2l=\frac{128-2l}{2}\\\\176-4l=128-2l\\176-128=4l-2l\\\frac{48}{2}=l\\\\24=l[/tex]

Therefore, the length of the original rectangle is 24 m.

Answer:

Length  of original rectangle = 24 m

Step-by-step explanation:

Perimeter of rectangle

P = 2(l + b)

l - length and b - width

It is given that,the perimeter of a rectangle is 88 m. If the width were doubled and the length were increased by 12 m, the perimeter would be 152 m

Perimeter of original rectangle = 88 m

2(l + b) = 88

l + b = 44

b = 44 - l

To find length and width

length l = l + 12  and width = 2(44 - l) then,

Perimeter = 152 m

we can write,

2( l + 12 + 2(44 - l)) = 152

l + 12 + 88 - 2l = 152/2 = 76

100 - l = 76

l = 100 - 76 = 24

Therefore length = 24 m

width = 44 - l = 44 - 24 - 20 m

$17.50 per hour and $1,500 bonus at the end of the year, that is, at the ends of the 52 weeks.

If you work 35 hours per week for 52 weeks, with this plan, you gain

[tex]17.50 \times 35 = \$ 612.50[/tex]

Then, after 52 weeks: [tex]\$612.50 \times 52=\$ 31,850[/tex]

So, with the first plan, you make $31,850 + $1,500 = $33,350.

Just $32,000 per year. It's a little bit better than the first situation.

$18.50 per hour.

So, per week would be: [tex]18.50 \times 35 = \$647.50[/tex]

After 52 weeks you make: [tex]\$647.50 \times 52=\$33,670[/tex]

So, with the third plan, you make $33,670.

$30,000 per year with a 5% bonus, which mean

[tex]30,000 + 0.05(30,000)=30,000+1,500=31,500[/tex]

So, with this plane you make $31,500 a year.

Therefore, as you can deduct, the best option is the third plan, $33,670 per year.

Answer:

The value of cosФ = -√5/3

Step-by-step explanation:

∵ sinФ = 2/3

∵ tanФ is less than 0

* Lets think about that:

 the value of sin is positive and the value of tan is negative

 according to ASTC rule:

 - All are positive in the first quadrant

 - sin only positive in the second quadrant

 - tan only positive in the third quadrant

 - cos only positive in the fourth quadrant

∴ Angle Ф lies on the second quadrant

∴ The value of cosФ is less than 0

∵ sin²Ф + cos²Ф = 1

∵ sinФ = 2/3

∴ (2/3)² + cos²Ф = 1

∴ cos²Ф = 1 - 4/9 = 5/9

∴ cosФ = ± √5/3

∵ Angle Ф lies on second quadrant

∴ cosФ = -√5/3

The cosine of the angle θ, given that sine θ is 2/3 and tangent θ is negative, is -√(5/9) since the angle is in the second quadrant.

If the sine of an angle (θ) is 2/3 and the tangent of that angle is less than zero, this indicates that the angle is in the second or fourth quadrant, where tangent values are negative. However, since sine is positive, the angle θ must be in the second quadrant. To find the cosine of θ, we can use the Pythagorean identity: sin² θ + cos² θ = 1. Substituting the sine value, we get (2/3)² + cos² θ = 1, which simplifies to 4/9 + cos² θ = 1. Solving for cosine gives us cos² θ = 1 - 4/9 = 5/9. The cosine value itself will be negative because cosine is negative in the second quadrant, so cos θ = -√(5/9).

The nth term of the sequence can be expressed as:

[tex]T_n = -4n + 23[/tex]

Since term to term rule is to take away 4, thus when we go back in sequence, the rule will be to add 4 term to term.

Thus:

Second term = 4 + third term = 4 + 11 = 15

First term = 4 + second term = 15 + 4 = 19

Since the given sequence has a constant difference of -4 between each adjacent terms, thus it is an arithmetic progression with d = -4

The nth term of an arithmetic progression with difference d is given by:

[tex]T_n = T_1 + (n-1) \times d[/tex]

Since d = -4 and first term is 19, thus we have:

[tex]T_n = 19 + (n-1) \times (-4) = -4n + 23\\T_n = -4n + 23[/tex]

Thus, the nth term of the sequence can be expressed as:

[tex]T_n = -4n + 23[/tex]

The expression for the nth term of the given sequence is 23 - 4n. Starting from the third term which is 11, we find the first term and use the common difference to write the formula.

The student is dealing with a linear sequence and is asked to write an expression for the nth term of the sequence based on the term-to-term rule 'take away 4'. To find the nth term of this arithmetic sequence, we need to use the structure of arithmetic sequences, which follow the pattern a_n = a_1 + (n - 1)d, where a_n is the nth term, a_1 is the first term, n is the term number, and d is the common difference between terms. Because we know that the third term is 11, we can backtrack to find the first term by adding 4 twice (since we have been taking 4 away to move forward in the sequence). Therefore, the first term a_1 is 11 + 4 + 4 = 19. Given the common difference is -4 (since we are taking away 4 each time), our nth term expression is a_n = 19 + (n - 1)(-4) or simplified a_n = 23 - 4n.

Final answer:

The probability of Robert eating two mint sticks consecutively from a bag of candy is 3/95, which is found by multiplying the individual probabilities of selecting a mint stick on the first and second draw.

Explanation:

The question involves calculating the probability that the first two pieces of candy Robert eats are both mint sticks. To find this probability, follow a step-by-step process to consider all possible outcomes.

Step 1: Probability of first mint stick

Initially, Robert has 20 pieces of candy with 4 being mint sticks. So, the probability of picking a mint stick first is:

4 mint sticks / 20 total pieces = 1/5 or 0.20.

Step 2: Probability of second mint stick

After eating one mint stick, there remain 3 mint sticks out of 19 total pieces. Thus, the probability now becomes:

3 mint sticks / 19 total pieces = 3/19.

Step 3: Combined probability

To find the probability of both events happening consecutively, multiply the separate probabilities:

(1/5) * (3/19) = 3/95, which simplifies to 0.0316, or about 3.16% chance.

Therefore, the correct answer is C. 3/95.

Step-by-step explanation:

1.

Area of a circle is given by the formula  A = πr²

where

A is the area,

r is the radius of the circle

From the given diagram, we can see that the radius is 11, hence the area will be:

[tex]A=\pi r^2\\A=\pi (11)^2\\A=121\pi[/tex]

The answer is  [tex]121\pi[/tex] units^2

2.

The unshaded secctor and the shaded sector equals the circle. We know that circle is 360°. The unshaded sector has an angle of 217°. So the shaded part will be 360 - 217 = 143°

The measure of the central angle of the shaded sector is 143°

3.

Area of a sector is given by the formula  [tex]A=\frac{\theta}{360}*\pi r^2[/tex]

Where

[tex]\theta[/tex] is the central angle of the sector (in our case it is 143°)

r is the radius (which is 11)

Plugging in all the info into the formula we have:

[tex]A=\frac{\theta}{360}*\pi r^2\\A=\frac{143}{360}*\pi (11)^2\\A=150.99[/tex]

rounding to the nearest whole number, it is 151 units^2
