[tex]\frac{11}{36}[/tex] yard

Step-by-step explanation:

Length of string Mrs. Ruiz has = [tex]\frac{11}{12}[/tex] yard

Mrs. Ruiz needs to hang 3 banners using the string.

Having known that each banner uses same length of string to be hung we can divide total length of sting into 3 equal parts.

So, we can divide [tex]\frac{11}{12}[/tex] yard by 3 as

⇒ [tex]\frac{11}{12}\div 3[/tex]

Changing the division sing to multiplication by taking reciprocal of divisor.

⇒ [tex]\frac{11}{12}\times \frac{1}{3}[/tex]

We can now multiply numerators and denominators.

⇒ [tex]\frac{11}{36}[/tex] yard

∴  Mrs. Ruiz must used  [tex]\frac{11}{36}[/tex] yard of string for each banner.

Answer: B

Step-by-step explanation:

The common factor missing from both sets of parentheses in the polynomial 10x^3 + 35x^2 - 4x - 14 when factored by grouping is (2x + 7).

To factor the polynomial 10x3 + 35x2 - 4x - 14 by grouping, we must first split the polynomial into two pairs that have a common factor. We can pair the terms as follows: (10x3 + 35x2) and (-4x - 14).

Factoring out the greatest common factor from each pair, we get:

5x2(2x + 7)

-2(2x + 7)

Now, we can observe that both pairs contain the common factor (2x + 7). So, the polynomial can be re-written using this common factor:

5x2(2x + 7) - 2(2x + 7)

Drawn out completely, the factored form of the polynomial using the distributive property (also known as factoring by grouping) thus becomes:

(5x2 - 2)(2x + 7)

Given expression is:

By substituting the value of "b" in the given expression, we get

→ [tex]a + \frac{3}{4} = 21[/tex]

→       [tex]a = 21 - \frac{3}{4}[/tex]

By taking L.C.M, we get

             [tex]= \frac{84-3}{4}[/tex]

             [tex]= \frac{81}{4}[/tex]

Thus the response above is correct.

Step-by-step explanation:

A box of cereal states that there are 93 calories in a three fourths-cup serving. What is the unit rate for calories per cup?

126.7 ~= 127 calories

How many calories are there in 2 cups of the cereal?

127 *2 = 254 calories.

The unit rate for calories per​ cup is 124 calories and 2 cups of the​ cereal contain 248 calories.

The unitary method is a technique for solving a problem by first finding the value of a single unit, and then finding the necessary value by multiplying the single unit value.

Given is a box of cereal which states that there are 93 calories in a

(3/4)th of a cup serving.

We can write -

3/4 cup serving contain → 93 calories

1 cup serving will contain → (93 x 4)/3 which is equivalent to 124 calories

Similarly, we can calculate for 2 cups of serving as -

1 cup → 124 calories

2 cups → (2 x 124) = 248 calories

Therefore, the unit rate for calories per​ cup is 124 calories and 2 cups of the​ cereal contain 248 calories.

Answer:

about $2,557

Actual cost : $2556.97

Step-by-step explanation:

well since all of them are .99 if you round to the hundreths it make another dollar cause it will force the .9 to become 1.0

so it be 1450 for the refrigerator, 490 for the dishwasher, and 617 for the electric range.

add those numbers to get about $2,557

We can see here that the cost of the food bill and tip before sales tax was approximately $253.20.

To find the cost of the food bill and tip before sales tax, you first need to calculate the tip amount and then add it to the food bill.

Given:

Food bill = $214.58

Tip rate = 0.18 (18% expressed as a decimal)

First, calculate the tip amount:

Tip = Food bill × Tip rate

Tip = $214.58 × 0.18

Tip = $38.6244 (rounded to two decimal places)

Tip ≈ $38.62

Now, add the food bill and the tip to find the total cost before sales tax:

Total cost = Food bill + Tip

Total cost = $214.58 + $38.62

Total cost = $253.20

Therefore, the cost of the food bill and tip before sales tax was approximately $253.20.

Answer:

q = 8

Step-by-step explanation:

Given the 2 equations

p + q = 36 → (1)

p - q = 20 → (2)

Add the 2 equations term by term

2p = 56 ( divide both sides by 2 )

p = 28

Substitute p = 28 into (1)

28 + q = 36 ( subtract 28 from both sides )

q = 8

If p + q = 36, and p -q = 20, then q = B

The given question is an example of an algebraic equation that involves the use of BODMAS and the substitution method.

Let

From equation (1)

Let p = 36 - q.

Then we can substitute the value of p into equation (2)

p - q = 20

36 - q - q = 20

36 - 2q = 20

collecting the like terms

-2q = 20 - 36

- 2q = - 16

Divide both sides by (-2)

q = -16/-2

q = 8

Therefore, we can conclude that the value of q = 8

Step-by-step explanation:

5/10 and 1/2 are both equivalent ratios resulting in half of themselves you can multiply these by any numbers but they will stay as half ratios such as 1:2 x 6 it would be 6:12 divide it by 6 and you have a half

Equivalent ratios have a multiplicative relationship, where multiplying both terms of a ratio by the same number results in another equivalent ratio. For example, multiplying the ratio 1:2 by 2 gives the equivalent ratio 2:4, showing that the ratios are proportional to each other.

Understanding Equivalent Ratios through Multiplication

We can explore the concept of equivalent ratios by looking at their multiplicative relationship. For instance, let's consider the ratios 1:2 and 2:4. These two ratios are equivalent because if we multiply both terms of the first ratio by 2, we get the second ratio. Mathematically, this can be expressed as 1x2/2x2 = 2/4, which is the same as the second ratio. Hence, the multiplication of both the numerator and the denominator of the first ratio by the same number (in this case, 2) maintains the ratio's equivalence to the second ratio.

This concept is crucial when dealing with proportions, unit rates, and unit scales. For example, if a map uses a unit scale of 1 inch = 100 feet, doubling the distance on the map to 2 inches would also double the actual distance to 200 feet, showing a direct multiplicative relationship between the two equivalent ratios.

Understanding how to use multiplication to find equivalent ratios is fundamental in solving problems that involve scaling, such as converting units or working with maps and models.

[tex]y = \frac{ - 4}{3} x + 3[/tex]

Step-by-step explanation:

[tex]using \: point \: slope \: form \\ y - y1 = m(x - x1) \\ y + 9= \frac{ - 4}{3} (x - 9) \\ y + 9= \frac{ - 4}{3}x + 12\\ y = \frac{ - 4}{3} x + 3[/tex]

The equation of the line in point-slope form passing through (9, -9) with a slope of -4/3 is y + 9 = -4/3 * (x - 9).

The point-slope form of a line's equation is expressed as y - y1 = m(x - x1). In this equation, 'm' represents the line's slope and (x1, y1) defines a particular point through which the line passes. In this scenario, the slope is given as '-4/3' and the point (9, -9). Consequently, by substituting these parameters into the point-slope form, we obtain the equation y - (-9) = (-4/3)(x - 9) or y + 9 = -4/3 * (x - 9).

Chairs are sold for $100 each, then x chairs cost $100x.

Tables are sold for $550 each, then y tables cost $550y.

Every day, the store can ship at most 21 pieces of furniture, then

7.5 pounds of muscles.

Step-by-step explanation:

Mr. Tan gained 5 pounds of solid fast twitching muscles during his last bulking phase lasting 24 days.

If this rate remains the same, then we can use the unitary method to calculate the amount of muscle he will gain in 36 days bulking phase.

Hence, within 24 days of the bulking phase, he gains 5 pounds of muscles.

So, within 36 days of the bulking phase, he will gain [tex]\frac{5}{24} \times 36 = 7.5[/tex] pounds of muscles. (Answer)

First, we calculated Mr. Tran's rate of muscle gain by dividing the total amount gained by the number of days. We then applied this rate to the asked time frame of 36 days. The result was approximately 7.48 lbs of muscle gain.

To solve this problem, we need to determine the rate of gain. Mr. Tran gained 5 lbs of solid fast twitching muscles in 24 days, so his rate of gain is 5 lbs / 24 days = 0.208 lbs/day. If Mr. Tran continues this rate for an extended period of 36 days, we can calculate the total gain by multiplying his daily rate by the number of days, i.e., 0.208 lbs/day * 36 days = 7.48 lbs. rounded to two decimal places.

So, if Mr. Tran’s bulking phase continues at the same rate for 36 days, he will gain approximately 7.48 lbs of muscle.

The kinetic energy of the roller coaster is 1600000 J.

Step-by-step explanation:

Given:

Mass of the roller coaster is 8000 Newton's and speed 20.0 meters/seconds.

Now, we need to find the kinetic energy [tex]E_{k}[/tex] of the roller coaster.

So, Mass of roller coaster (m) = 8000 N.

Velocity of roller coaster (v) = 20.0 m/s.

Now, putting the formula of kinetic energy:

[tex]E_{k} = \frac{1}{2}\times m\times v^{2}[/tex]

[tex]E_{k}=\frac{1}{2} \times 8000\times 20^{2}[/tex]

[tex]E_{k}=\frac{1}{2} \times 8000\times 400[/tex]

[tex]E_{k}=\frac{1}{2} \times 3200000[/tex]

[tex]E_{k}=1600000[/tex]

Therefore, the kinetic energy of the roller coaster is 1600000 J.
