Answer:

The number of footballs, basketballs and volleyballs were sold are 75, 36 and 15 respectively.

Step-by-step explanation:

Consider the provided information.

A football costs $35, a basketball costs $25  and a volleyball costs $15.

Let F represents the football, B represents the basketball and V represents the volleyball.

On a given day, the store sold 5 times as many footballs as volleyballs.

[tex]F=5V[/tex]......(1)

They  brought in a total of $3750 that day,

[tex]35F+25B+15V=3750[/tex]......(2)

The money made from basketballs alone was 4 times the money.

[tex]25B=4(15V)[/tex]......(3)

By equation 1, 2 and 3.

[tex]35(5V)+4(15V)+15V=3750[/tex]

[tex]250V=3750[/tex]

[tex]V=15[/tex]

Substitute the value of V in equation 1 and 3.

[tex]F=5(15)=75[/tex]

[tex]25B=4(15\times 15)\\B=36[/tex]

Hence, the number of footballs, basketballs and volleyballs were sold are 75, 36 and 15 respectively.

The system of equations is as follows:

35F + 25B + 15V = 3750

1 F = 5V

25B = 60V

Let's define the variables first:

We are given the following information:

We can write the system of equations as:

35F + 25B + 15V = 3750

F = 5V

25B = 60V

Apple Produce pays employees  38.5 for per bushels of apples picked.

Step-by-step explanation:

Given:

Apple produce pays it's employees by the formula;

[tex]P(b) = \frac{7}{2}b+35[/tex]

[tex]P(b)[/tex] ⇒ Employee's Total daily pay

[tex]b[/tex] ⇒ Number of bushels of apples

We need to find the Rate employees are paid per bushels of apples picked.

Rate employees are paid per bushels of apples picked can be calculated by substituting the value of "b = 1" in above formula.

Substituting the value of b = 1 in above formula we get;

[tex]P(1) = \frac{7}{2} \times 1+35\\[/tex]

Now We will take LCM to make the Denominator common.

[tex]P(1) = \frac{7}{2} +\frac{35\times 2}{2} = \frac{7}{2} +\frac{70}{2} = \frac{77}{2}= 38.5[/tex]

Hence Apple Produce pays employees  38.5 for per bushels of apples picked.

Answer:The remainder can be calculated by doing the following steps;

Step-by-step explanation:

The remainder when f(x) = x⁴ - 5x³ + 3x² - 2x +7 is divided by x - 1 is 4.

Polynomial is an expression that involves only the operations of addition, subtraction, multiplication of variables.

The remainder theorem states that when a polynomial, f(x), is divided by a linear polynomial , x - a, the remainder of that division will be equivalent to f(a).

Given that f(x) = x⁴ - 5x³ + 3x² - 2x +7 is divided by x - 1

x - 1 = 0

x = 1

f(1) = 1⁴ - 5(1)³ + 3(1)² - 2(1) + 7 = 4

The remainder when f(x) = x⁴ - 5x³ + 3x² - 2x +7 is divided by x - 1 is 4.

[tex]x = 2\sqrt{10}[/tex]

Step-by-step explanation:

We have to solve for x from the logarithmic equation as follows:

[tex]\log x^{2} + \log 25 = 3[/tex]

⇒ [tex]\log 25x^{2}  = 3[/tex]  

{Since, using logarithmic property [tex]\log A + \log B = \log AB[/tex]}

Now, converting this logarithmic equation above into exponential equation we get,

[tex]25x^{2}  = 10^{3}[/tex]  

{Since we know that if [tex]\log_{10}a = b[/tex] then, we can write [tex]a = 10^{b}[/tex]}

Para levantar 500 toneladas de mineral a una altura de 90 pies en una hora, se requieren aproximadamente 90.91 caballos de fuerza (HP), calculados utilizando la fórmula de trabajo y potencia.

Para calcular la potencia requerida en caballos de fuerza (HP) para levantar 500 toneladas de mineral hasta una altura de 90 pies en una hora, necesitamos utilizar la fórmula de trabajo y la potencia. La potencia se mide en unidades de trabajo por unidad de tiempo.

Primero, convirtamos la altura a pies a la misma unidad que la tonelada, que es la tonelada-pie (ton-ft). 1 tonelada-pie es igual al trabajo necesario para levantar una tonelada a una altura de un pie.

500 toneladas * 90 ft = 45,000 ton-pie

El trabajo total necesario es de 45,000 toneladas-pie.

Dado que el trabajo se realiza en una hora (3600 segundos), podemos usar la siguiente fórmula para calcular la potencia en HP:

[tex]\[Potencia (HP) = \frac{Trabajo (ft-lbf)}{Tiempo (s)} \times \frac{1}{550}.\][/tex]

Donde 1 HP es igual a 550 ft-lbf/s.

Sustituyendo los valores conocidos:

[tex]\[Potencia (HP) = \frac{45,000 \text{ ton-pie} \times 2,000 \text{ lbf/ton} \times 1 \text{ ft}}{3600 \text{ s} \times 550 \text{ ft-lbf/s}} = \frac{180,000,000 \text{ lbf-ft}}{1,980,000 \text{ ft-lbf/s}} \approx 90.91 HP.\][/tex]

Por lo tanto, se requieren aproximadamente 90.91 caballos de fuerza (HP) para realizar este trabajo en una hora.

Step-by-step explanation:

The cost of the camera if Sharon paid $78 sales tax at a rate of 6.5% is $1200

What was the cost of the camera?

Amount of sales tax = $78

Sales tax rate = 6.5%

Cost of the camera = x

.

Amount of sales tax = Sales tax rate × Cost of the camera

78 = 6.5% × x

78 = 0.065 × x

78 = 0.065x

Divide both sides by 0.065

x = 78/0.065

x = 1200

Therefore, the camera cost $1200

Answer:

The water she need is [tex]7\frac{7}{8} \ cups.[/tex] and strawberry syrup [tex]11\frac{13}{16}\ cups[/tex].

Step-by-step explanation:

Given:

Dina wants to make 15 3/4 cups of strawberry drink by mixing water and strawberry syrup with a ratio of 2 1/4 cup of water for every 3/4 cup of syrup.

Now, to find the quantity of water and syrup she need to use.

As given in question ratio so:

Strawberry syrup = 2 1/4 = 9/4.

Water = 3/4.

Total cups of strawberry drink = 15 3/4 = 63/4.

Let the strawberry syrup be [tex]\frac{9}{4} x[/tex].

And let the water be [tex]\frac{3}{4} x[/tex].

According to question:

[tex]\frac{9x}{4} + \frac{3x}{4}=\frac{63}{4}[/tex].

On adding the fractions:

⇒[tex]\frac{9x+3x}{4} =\frac{63}{4}[/tex]

⇒[tex]\frac{12x}{4} =\frac{63}{4}[/tex]

Multiplying both sides by 4 we get:

⇒[tex]12x=63[/tex]

Dividing both sides by 12 we get:

⇒[tex]x=\frac{63}{12}[/tex]

Dividing numerator and denominator by 3 on R.H.S we get:

⇒[tex]x=\frac{21}{4}[/tex]

Now, putting the value of [tex]x[/tex] on ratios:

Strawberry syrup =  [tex]\frac{9}{4}\times x=\frac{9}{4}\times\frac{21}{4}[/tex]

                             =  [tex]\frac{189}{16}[/tex]

                             =  [tex]11\frac{13}{16}\ cups[/tex]  

Water = [tex]\frac{3}{4}\times x =\frac{3}{4} \times\frac{21}{4}[/tex]

          = [tex]\frac{63}{8}[/tex]

          = [tex]7\frac{7}{8} \ cups.[/tex]

Therefore, the water she need is [tex]7\frac{7}{8} \ cups.[/tex] and strawberry syrup [tex]11\frac{13}{16}\ cups[/tex].

Final answer:

The ratio of legs to ears for Santa's reindeer is 2 legs/ear.

Explanation:

The question is asking for the ratio of legs to ears as it relates to Santa's reindeer. We know that Santa has 9 reindeer and reindeer typically have 4 legs and 2 ears. So the total number of legs would be 9 reindeer * 4 legs/reindeer = 36 legs. And the total number of ears would be 9 reindeer * 2 ears/reindeer = 18 ears. To find the ratio of legs to ears, we divide the number of legs by the number of ears: 36 legs / 18 ears = 2 legs/ear.

Answer:

The Cardboard dimensions are 13cm in length and 12cm in breadth

Step-by-step explanation:

We can use Pythagoras Theorem to find the length the Cardboard (a²+b²=c²). Let A be 5 and B be 12, we find that C is equivalent to 13. The height is 12, thus the breadth of the Cardboard is also 12. Hope this helps :)

Final answer:

The dimensions of the cardboard rectangle are 5 cm by 12√2 cm.

Explanation:

To determine the dimensions of the cardboard rectangle inserted diagonally into a box with given dimensions, we first need to calculate the diagonal of the box that lies in the length-height plane. The box is 12 cm long and 12 cm high.

By using the Pythagorean theorem, we can find the length of the diagonal 'd' using the formula √(l² + h²), where 'l' is the length of the box and 'h' is the height.

In this case, 'd' = √(12² + 12²) = √(144 + 144) = √(288) = 12√2 cm.

Thus, the dimensions of the cardboard rectangle are its width, which is 5 cm (the width of the box), and its diagonal, which is 12√2 cm.

Answer:

- [tex]\frac{24}{25}[/tex]

Step-by-step explanation:

Given 630 < A > 720 then A is in the fourth quadrant where

cosA > 0 and sinA < 0

Given

cosA = [tex]\frac{3}{5}[/tex] = [tex]\frac{adjacent}{hypotenuse}[/tex]

Then the triangle is a 3- 4 - 5 with opposite side 4, thus

sinA = - [tex]\frac{opposite}{hypotenuse}[/tex] = - [tex]\frac{4}{5}[/tex]

Using the trigonometric identity

sin2A = 2sinAcosA

         = 2 × - [tex]\frac{4}{5}[/tex] × [tex]\frac{3}{5}[/tex]

         = [tex]\frac{2(-4)(3)}{5(5)}[/tex] = - [tex]\frac{24}{25}[/tex]

Therefore the simplified given expression [tex]\frac{x^0y^{-3}}{x^2y^{-1}}=\frac{1}{x^2y^2}[/tex]

Step-by-step explanation:

Given expression is  [tex]\frac{x^0y^{-3}}{x^2y^{-1}}[/tex]

To simplify the given expression:

[tex]\frac{x^0y^{-3}}{x^2y^{-1}}[/tex]

Above expression can be written as

[tex]\frac{x^0y^{-3}}{x^2y^{-1}}=\frac{(1)y^{-3}}{x^2y^{-1}}[/tex]

(since [tex]x^0=1[/tex] ,anything variable to the power "0' is 1)

[tex]\frac{x^0y^{-3}}{x^2y^{-1}}=\frac{y^{-3}}{x^2y^{-1}}[/tex]

 [tex]\frac{x^0y^{-3}}{x^2y^{-1}}=\frac{1}{x^2y^{-1}y^3}[/tex]  (since [tex]a^{-m}=\frac{1}{a^m}[/tex] )

[tex]\frac{x^0y^{-3}}{x^2y^{-1}}=\frac{1}{x^2y^{-1+3}}[/tex]  (using the property [tex]a^m+a^n=a^{m+n}[/tex])

[tex]\frac{x^0y^{-3}}{x^2y^{-1}}=\frac{1}{x^2y^2}[/tex]

Therefore [tex]\frac{x^0y^{-3}}{x^2y^{-1}}=\frac{1}{x^2y^2}[/tex]

Therefore Option A) [tex]\frac{1}{x^2y^2}[/tex] is correct.

Therefore the simplified given expression [tex]\frac{x^0y^{-3}}{x^2y^{-1}}=\frac{1}{x^2y^2}[/tex]

There are approximately 275.59 inches in 7 meters.

To find out how many inches are in 7 meters, we will first convert meters to centimeters, and then centimeters to inches.

Since there are 100 centimeters in one meter, we can calculate:

7 meters × 100 centimeters/meter = 700 centimeters

Now, we know there are 2.54 centimeters in one inch, we can convert the 700 centimeters to inches:

700 centimeters × 1 inch/2.54 centimeters ≈ 275.59 inches

To the nearest inch, there are approximately 275.59 inches in 7 meters.
